Full textAbstract:
This work provides an innovative solution for monitoring fatigue for users behind workstations. A web camera was adjusted to work in near infrared range and a system of 880 nm IR diodes was implemented to create an IR vision system to localize and track the eye pupils. The software developed monitors and tracks eyes for signs of fatigue by measuring PERCLOS. The software developed runs on the workstation and is designed to draw limited computational power, so as to not interfere with the user task. To overcome low-frame rate imposed by the hardware limitations and to improve real time monitoring, two-phases detection and tacking algorithm is implemented. The proposed system successfully monitors fatigue at a rate of 8 fps. The system is well suited to monitor users in command centers, flight control centers, airport traffic dispatches, military operation and command centers, etc., but the work can be extended to wearable devices and other environments.

Full textAbstract:
This thesis documents the design details, development, and field testing of an advanced power system harmonic monitor. It begins by reviewing present harmonic standards and harmonic monitoring equipment. It then goes on to describe the design and field use of the first generation harmonic monitor. From the field use a number of problems with this monitor are identified leading to the second generation harmonic monitor known as CHART II. The acronym CHART means Continuous Harmonic Analysis in Real-Time. The design of the monitor including the data acquisition and computer processing equipment, as well as the display system, is such that it can acquire multiple channels of power system signals from remote locations. It can compute the harmonics of these signals continuously on a cycle-by-cycle basis, and store only the harmonics of interest. Harmonic computation is performed in real-time, with results displayed as they occur. Acquired data can be accurately time stamped for comparison with data from other monitoring sites, enabling simultaneous measurement at remote locations. The key areas of technology involved in implementing such an instrumentation system are: data acquisition from power system equipment, digital fibre optics, real-time digital signal processing, high speed multiprocessing bus systems, real-time multitasking operating systems, global positioning satellite systems, and computer networking. The application of digital signal processing to power system harmonic measurement is covered, and a field trial with the CHART II monitor is documented.

In this work we develop new algorithms for video comparison, for video alignment, and for determining the similarity between entire video clips or detecting similarities between sub-videos. The intent of this work is to develop video-based techniques for autonomous monitoring of systems in industrial, manufacturing, and research environments. We develop an algorithm, Dynamic Time and Space Warping, to determine a model-free similarity between an example and an unknown video. The algorithm optimally shifts space and warps time according to local measures of video similarity. The resulting similarity measure is an optimal path of similarity versus space and time used to optimally align or compare the two video. We demonstrate the applicability of such similarity measures to industrial wear monitoring, failure prediction, and assembly-line feedback control and to non-industrial settings with examples in sports and entertainment. We extend the similarity machinery and introduce a new technique for video event-detection. The local similarity is integrated along the optimal space-time path in order to determine a cumulative similarity.
(cont.) We demonstrate the applicability to content query and surveillance; we identify the temporal and spatial location inside of a large video stream which is similar to a query, or template, video. We explore applications in video classification. We investigate the performance degradation and robustness of the algorithms to noise via distortion of real examples and simulation. We develop techniques to aid engineers in the selection of a video template that is relevant to their monitoring application and locally robust to noise. We explore the structure and computational complexity of the algorithms. We demonstrate that the algorithms are highly-parallelizable and that the fast processing rates necessary for many industrial monitoring applications are achievable.

Full textAbstract:
Prodding is a procedure which is normally employed in the process of demining. Itis performed by probing the ground in order to detect the presence of sub-surfacemines and/or unexploded ordnances.The Swedish Armed Forces via SWEDEC runs a demining school in Eksjö.The demining school educates personnel from amongst others the Swedish PoliceService and the Swedish Armed Forces in courses involving demining. Prodding isa vital part of their training. The school has experienced problems with teachinggroups of students in prodding. This thesis is a system development of a proddingmonitoring system that will facilitate the teaching of the prodding method bysupervising groups of students individual prodding performances. The monitoringsystem is based on equipping prodders with sensors measuring their motion. Themeasured information is continuously and wirelessly sent from the sensors to asoftware system that visualizes and stores it in a database.
Minpikning är en aktivitet som normalt innefattas som en del av en minröjningsprocess. Minpikning innebär att man lokaliserar landminor eller oexploderad ammunition genom att försiktigt känna sig för i marken med ett spetsigt föremål.
Försvarsmakten driver genom SWEDEC amröjskolan i Eksjö. Amröjskolan utbildar personal från bl.a. polisen och försvarsmakten i kurser rörande minröjning och ammunitionsröjning. Ett vitalt moment i utbildningen är att lära ut minpikning, något som de har upplevt svårigheter att lära ut i grupp. Det här examensarbetet är en systemutveckling av ett övervakningssystem som ska underlätta undervisningen i minpikning genom att övervaka en grupp elevers enskilda minpikningsutföranden. Övervakningssystemet bygger på att utrusta minpikar med sensorer som mäter dess rörelser. Den uppmätta informationen förs kontinuerligt och trådlöst från sensorerna till ett mjukvarusystem som visualiserar samt lagrar den i en databas.

The manufacturing industry is constantly looking for ways to reduce production costs and at the same time to increase productivity. Automation of common manufacturing operations is one of these methods. By automating common manufacturing operations; various machines, robots, control systems and information technologies are used to reduce the overall human input requirement (mental and physical). Recent advances in technology have made it possible to now also automate (or facilitate) the maintenance requirement of these machines and tools. Modern tools and machines, which can estimate when it will fail or when failure is imminent have obvious advantages for predictive maintenance purposes. Another function of this technology is to determine how efficiently a tool or machine operates, or what the quality of the produced goods is. Predictive maintenance can decrease manufacturing plant or machine down times – which have a positive effect on cost-savings – has gained considerable importance over the last two decades.

Along with the popularization of the SMS (Short Message Service) as a communication tool among big companies, such as flight and train companies, post offices and banks, a new branch started to take place in the mobile communication industry: bulk-SMS business. The companies send the SMS to their costumers through an aggregator, which in turn send the SMS further to the customers’ mobile phone. The aggregator consequently needs to monitor the SMS traffic constantly so they can assure good quality of their services. In case of an interruption in the system, their support group needs to be notified directly, so the problem can be fixed straightaway. The aim of this project was to develop an application integrated to the intranet of a company that works in the business of bulk-SMS (CLX Networks), in order to replace the current monitoring system, called OpenNMS. The system was developed using Zend Framework (PHP) and MySQL database.The project resulted in an application that allows the administrator to configure alarms and notifications and to add clients and suppliers accounts to the monitoring system. Whereas the interaction between the user administrator and the system is already implemented, the connection between the system and the CDR- and RR-database is still under development.

Full textAbstract:
Wireless Sensor Networks (WSNs) are essential technologies for environmental monitoring. They are composed of small electronic devices, which can monitor, collect and report environmental data autonomously and continuously with respect to energy consumption and accuracy of data. Recently, mobile phones have become integral part of our daily lives. They have been widely used as mobile sensors to monitor the human behaviour and emotion. Mental problem is becoming a global concern in modern society. Some of the psychological problems, such as Seasonal Affective Disorder (SAD), may cause depression and sickness due to the lack of sunlight in long and dark winters. In this master thesis, we design a system, named Seasonal Affective Disorder Monitoring (SADM), to measure human sociability and light exposure to study the SAD psychological problem among people. The goal of this work is to monitor and improve the mental and physical health of people in our society. The system utilizes both stationary sensors and mobile sensors for monitoring light intensity and human activities continuously, which can help us to learn more about their mental and physical health in diff( erent seasons. The results give us a history of the level of the people's activity and also the percentage of light intensity in the environment and light intensity that individuals received in daily life. Using this information, we analyse the relation between human behaviour and seasonal changes.

Full textAbstract:
The aim of this work was to develop sensory devices and data acquisition system to facilitate investigations into the mechanics of the rowing system, comprising the rower(s), boat and oars. As such, the parameters to be measured were: boat and seat position, velocity and acceleration; oar force; foot force; oar angle and rower heart rate.
An oar force sensor was designed that fitted into the cavity of a modified oarlock. This sensor design is cheap, yields sound results and its presence is almost not noticeable to the rower. A review of previously applied methods of oar force measurement, predating 1900, is included.
Foot force is of interest to many different fields of research, thus there is a large amount of literature on the subject of foot force measurement. A comprehensive review of this literature is used to aid in the design of the required sensor. The combination of a non-simple dynamic loading (i.e. time varying spatially distributed normal and shear forces), with static foot position distinguishes the problem of measuring the force under the feet during rowing from most previously considered cases. A strain gauge-based force sensing plate was designed to measure both normal force distribution and unidirectional shear force under the feet. Sample results are presented from a study with international class New Zealand rowers on a rowing ergometer. The sensor, performs well under normal force loadings, but needs modification to measure shear accurately. Possible modifications are suggested.
While only a single oar angle, known as the sweep angle, was required to be measured, a sensor combination capable of measuring the spatial orientation of the oar relative to the boat was conceived. A new method of relative orientation estimation, via approximation of the Rodrigues' vector, which allows relative weighting of sensory data, was derived. Unfortunately, calibration issues prevented the gathering of meaningful data in the time available. A full theoretical development, including a new calibration scheme, which should alleviate the encountered problems, is included.
While the motion of the rower within the boat is an important consideration in the dynamics of the rowing system, few previous researchers have measured it. These previous methods are briefly described, before the sensor used in this study, the optical rotary encoder, is detailed. Differentiation of the encoder signal to obtain seat velocity and acceleration relative to the boat was achieved using a purpose designed simple Kalman filter.
The kinematic parameters of the boat, i.e. position, velocity and acceleration were measured using a combination of accelerometer and submerged impeller. The information from these two sensors was combined using a variant of the Kalman filter used in the differentiation of the encoder signal. The combination of the seat and boat kinematics allows study of the motion of the system centre of mass.
Supplying power to, and collecting data from the above sensory devices was a purpose built data acquisition system dubbed ORAC (On-the-water Rowing Acquisition Computer). ORAC was designed to transmit the collected information, in real-time, to a remote laptop computer via wireless LAN, but the system used proved to have insufficient range, and hence ORAC was used as a standalone computer.

There is a need for flexible, inexpensive metering technologies that can be deployed in many different monitoring scenarios. Individual loads may be expected to compute information about their power consumption. Utility providers, facilities managers, and other consumers will likely find innumerable ways to mine information if made available in a useful form. However, appropriate sensing and information delivery systems remain a chief bottleneck for many applications, and metering hardware and access to metered information will likely limit the implementation of new electric energy conservation strategies in the near future. This thesis presents solutions for two long standing problems in nonintrusive power and diagnostic monitoring. First, a high-resolution, physically windowed sensor architecture that is well-suited for energy score-keeping and diagnostic applications will be discussed. The sensor can track a large-scale main signal while capturing small-scale variations. The prototype system uses digital techniques to reconstruct an observed current with a high effective bit resolution. The sensor measures a small current signal using a closed-loop Hall sensor. and extends the range by driving a compensation current with a high performance current source through an auxiliary winding. The system combines the compensation command and the sampled output of the residual sensor to reconstruct the input signal with high bit resolution and bandwidth. Second, a long-standing problem in nonintrusive power monitoring involves the tracking of power consumption in the in the presence of loads with a continuously variable power demand. Two new techniques have been developed for automatically disaggregating, in real-time. different classes of continuously variable power electronic loads which draw distorted line currents. Experimental results of the proposed power estimator extracting the power consumption of common variable power loads such as a variable speed drive, a computer, and a light dimmer are presented.

Full textAbstract:
Infection control is a key aspect of wound management strategies. An infected wound results in chemical imbalances in the wound and may lead to prolonged healing times and wound surface degradation. Wound dressings changes may result in damage to healing tissues and an increased risk of infection. This thesis presents details of a measurement system based on sensors that can be placed at the wound-dressing interface and potentially monitor the bacteria in real time. Two systems were developed, one to grow bacteria in suspension and the second to encourage biofilms to grow on the electrode surfaces. Both systems allow the electrical impedance to be measured and were used to evaluate the impedance characteristics of bacterial growth with two sensor materials, silver-silver chloride and carbon. The bacteria Staphylococcus aureus and Staphylococcus epidermidis were selected as species commonly isolated from wounds. The growth of bacteria was confirmed by plate counting methods from the suspensions and by microscopy staining techniques of the biofilms. The impedance data was analysed for discernible differences in the impedance profiles to distinguish the absence and/or presence of bacteria. Equivalent circuit modelling was performed to provide further information on the physical processes occurring within the systems. The main findings were that the impedance profiles of silver-silver chloride sensors in bacterial suspensions could detect the presence of high cell densities. However, the electrodes tended to inhibit the growth of bacteria and also prevented biofilms forming on the electrode surfaces. The Staphylococcus aureus strains adhered to the carbon sensors and in at least one strain the impedance profiles had discernible differences. All the strains with carbon sensors produced noticeable differences in the equivalent circuit model analysis. These results show that there is potential to create a real-time infection monitor for wounds.

November 2013Pole mounted transformers (PMT) in rural areas present an opportunity for local utilities to do current monitoring on these systems. These transformers are exposed to abnormal amounts of stress due to the vast power demand in these areas. The aim of this study is to develop a more cost-effective condition monitoring system. Transformer current monitoring can be a dangerous practice if not done by suitably trained utility electricians. Hence this study is partly aimed at the elimination of hazardous working environments associated with manual electrical measurements. An investigation to determine a safe and cost-effective way to obtain the electrical measurements required from PMTs is undertaken. Although current measurements can be done with a current clamp-on meter, these measurements still take place at the phases of the transformer and are unsafe. The possibility of implementing wireless data gathering on current clamp-on meters is therefore investigated. This is made possible by a wireless sensor node (WSN) which gathers information and transmits it wirelessly to a WSN base station. This wireless solution is battery powered, necessitating battery replacements, therefore leading to the investigation of magnetic fields, magnetic materials and magnetic induction. A current clamp able to generate a high voltage (HV) output with minimal magnetic field strength is developed. The magnetic fields produced by the transformer’s phase cables are used to generate an alternating voltage. With the help of a microcontroller and an energy harvesting circuit, this voltage is converted and used to charge supercapacitors. The magnetic fields are also used to determine the current flow in the transformer phase cables when the device is not in energy harvesting mode. The device will then undergo comprehensive laboratory testing to determine its accuracy and durability, and is then used to do ‘real life’ current measurements, the results of which are compared against an off-the-shelf current monitoring device.

Full textAbstract:
Sleep related vehicle accidents have been under publicised but remains as one of the main causes of road traffic accidents, as much as drink driving. This research aims to reduce this worldwide problem by developing a system to monitor fatigue driving. The thesis describes the research into the application of chromatic data processing techniques to detect early physiological and physical indicators of fatigue. Physiological factors that influence drivers are based on the duration of the drive, how much rest they have throughout the journey and the quality of sleep they had prior to the drive. The physiological indicator algorithm of the system is developed to take account of these factors and calculates the tiredness level. The chromatic technique is then used to analyse the results to establish trends and signatures of early fatigue situations where a warning system can be introduced. The chromatic signatures of fatigue have been established using results from 20 road tests conducted by professional drivers. Physical indicators such as early drowsy driving are detected by monitoring the behaviour of the vehicle. Micro sleep (e.g. head nodding, slow eye-blinking) can lead to lane drifting and vehicle swerving. These events are being regarded as early physical signs of sleepy driving. The main sensor for detecting the lateral yaw motion of the vehicle is a miniaturised gyroscope. Chromatic analysis is applied to the gyroscope output to identify and differentiate fatigue related events (e.g. swerves and lane drifting) from normal driving (e.g. left and right turning, roundabouts and bumpy roads) Combining the extracted information of the physiological and physical indicators, a Chromatic Fatigue Driving System can be developed as a tail safe system which monitors and alerts driver during critical fatigue conditions.

Home surveillance is a major concern in this day and age as with the rapid increase in the technology around us. There is a need to get updated with new possibilities to make our lives better and easy. Some cases and situations exhibit the need for home monitoring. So, we set out to discover a solution to this problem of home monitoring. Generally, we have issues with pets and kids alike such as approaching dangerous places like electric switches, stairs, and hot things. Not only a problem with kids and pets but also a chance of burglary and stranger's unusual activities. To overcome this problem we are designing and prototyping a system to keep an eye on kids, pets, and older people. This system is used in other applications like theft monitoring. The device can monitor the field all the time. In this way, this system helps in-home monitoring. The system consists of Arduino, which is the brain of the system, the PIR sensor, ESP32-CAM, and buzzer. The PIR sensor detects motion then gives input to the Arduino. Arduino gives output to the ESP32-CAM and buzzer. The ESP32-CAM can be activated and sends information to the user through the web Interface and the application. The user can see the video streaming on the PC screen or any other display. The buzzer can emit a high volume signal indicating that "there is an alert at the home".

Full textAbstract:
The protection of power distribution and transmission systems is a critical application in ensuring safe, reliable and efficient supply of electricity to the consumers. The protection allows for the mitigation of damage due to various network faults, preventing equipment damage and reducing downtime that can often result.
Within the University there is a collection of digital protective relays manufactured by Schweitzer Engineering Laboratories, where the functionality, requirements and operational knowledge of the available devices remains largely unknown. Thus this thesis was tasked with drawing out this knowledge and providing a means of demonstrating the functions of the available devices.
In order to develop this understanding the project was divided into several components; familiarisation, investigation, Simulator development and operations testing.
The familiarisation and investigation components of the project allowed for acquisition of the required level of knowledge about the devices to enable development of a suitable Simulation platform to demonstrate the functional operations and applications of the available devices. This portion of the project yielded the required details about the scope of the protective functionality, the mechanisms and requirements to program this functionality and the operation requirements. This resulted in the construction of a hardware based Simulation platform, provided through Lab-Volt equipment, demonstrating the functional capability of the Transformer Protection Relay. The testing component provided a mechanism to ensure that the simulation and relay would demonstrate the available functionality as expected.
The simulation platform can be used to demonstrate the overcurrent and differential protection functionality along with providing an operable insight into the relay monitoring and metering capabilities. Hardware limitations prevented a truly realistic simulation being developed and tested, notably the low fault levels and restricted fault types available. However the construction of this Simulator has demonstrated the acquired knowledge of the relays and provided the groundwork to extend the Simulator to incorporate further relays and protective functionality.

Full textAbstract:
Recent large-scale blackouts revealed that power systems around the world are far from the stability and reliability requirement as they suppose to be. The post-event analysis clarifies that one major reason of the interconnection blackout is lack of wide area information. Frequency dynamics is one of the most important parameters of an electrical power system. In order to understand power system dynamics effectively, accurately measured wide-area frequency is needed. The idea of building an Internet based real-time GPS synchronized wide area Frequency Monitoring Network (FNET) was proposed to provide the imperative dynamic information for the large-scale power grids and the implementation of FNET has made the synchronized observations of the entire US power network possible for the first time. The FNET system consists of Frequency Disturbance Recorders (FDR), which work as the sensor devices to measure the real-time frequency at 110V single-phase power outlets, and an Information Management System (IMS) to work as a central server to process the frequency data. The device comparison between FDR and commercial PMU (Phasor Measurement Unit) demonstrate the advantage of FNET. The web visualization tools make the frequency data available for the authorized users to browse through Internet.
The research work addresses some preliminary observations and analyses with the field-measured frequency information from FNET. The original algorithms based on the frequency response characteristic are designed to process event detection, localization and unbalanced power estimation during frequency disturbances. The analysis of historical cases illustrate that these algorithms can be employed in real-time level to provide early alarm of abnormal frequency change to the system operator. The further application is to develop an adaptive under frequency load shedding scheme with the processed information feed in to prevent further frequency decline in power systems after disturbances causing dangerous imbalance between the load and generation.Ph.

The study in this report mainly focuses on the Internet-based Monitoring and Controlling of a Real-Time Dynamic System interfaced via a dedicated local computer. The main philosophy behind this study is to allow the remote user to conduct an Internet-based Remote Operation (I-bRO) for the dynamic system. The dynamic system has been defined as the system which has its parts interrelated in such a way that a change in one part necessarily affects other parts of the system [I]. In order to achieve this goal, the study has been conducted in a form of an on-line and real-time Virtual Laboratory (VL). Through this form of laboratory, a user can carry out the experiment, perform real-time monitoring and controlling operations of the experiment and collect real and live data from the experiment through the network link as the user was physically in the laboratory. The dynamic system that has been selected for the test-rig of this study is a 3-phase Induction Motor (IM) which is mechanically coupled with a DC-Dynamometer that acts as a variable load to the IM. This system is a common laboratory experiment in the study of the Electrical Engineering for both undergraduate and postgraduate students. The study covers both sides of the I-bRO; the hardware and the software. The hardware side includes the design and the development of a load control box that has been used to interface the DC-Dynamometer and consequently control it from the local computer. The software side covers the design and the development of the Virtual Instrumentation System (VIS) that has replaced successfully the physical Measurement and Test (M&T) instruments of the test-rig. Beside that, the software side includes the development of the internet remote front panel for the remote operation.Furthermore, the software side includes the development of the software that has been used to analyse the system during the I-bRO. In this study, the LabVTEW7 program has been used to design and develop the VIS and the Matlab program has bee used to aualyse the system performance for the remote operations. This study also addresses the issues and problems related to the intranet or the internet to be used as the network for data communication between the test-rig and remote users. This study has been carried out in different stages as follows: 1. Designing and development of the VIS. 2. Interfacing the test-rig apparatus with a local computer. 3. Upload the system from the local computer to the network. 4. Study the performance of the system on the network for the purpose of the remote operations controlled over the internet. The developed system of this study has been used for data acquisition, network communications, instruments monitoring and controlling applications. A user can execute on-line and in the real-time the developed VIS from any point in the university. Due to the fact that the university network is directly integrated to the main internet server. a remote user through the main internet server is able to perform I-bRO of the selected dynamic system. There are many factors associated with the network, the internet or the intranet, and have direct influences on the control system performance throughout the remote operations. The most dominant factors are the random time-delays and the data losses.These factors among others have to be addressed for a proper application of the I-bRO. For this reason, different cases and scenarios of the I-bRO have been investigated and simulated to study the affection of the network on the control system performance. The system is analysed under two control cases, closed loop with random time-delays and open loop when the internet server is disconnected and no communication between the input and the output of the system. In the first case, the closed loop, the internet server is assumed to be closed and subjected to random time-delays. In the second case, the internet server is subjected to random cut-off and thus opens the control loop. The results of both cases have been analysed and discussed. It has been found that, if the control system without the time-delays is stable, it remains stable even with small time-delays up to twenty seconds. This result is different from what has been shown in the literature.

This thesis investigates embedded databases and graphical interfaces for the MicroBaseJ project. The project aim is the development of an integrated database and GUI user interface for a typical 3G, or 2.5G, mobile phone with Java MIDP2 capability. This includes methods for data acquisition, mobile data and information communication, data management, and remote user interface. Support of phone delivered informatics will require integrated server and networking infrastructure research and development to support effective and timely delivery of data for incorporation in mobile device-based informatics applications. A key research and development (R&D) challenge is to support effective and timely delivery of data for incorporation in mobile device-based informatics applications. Another important aspect of the project is determining how to develop efficient graphics for the small mobile screen. The research investigates and analyses the architecture of a mobile monitoring system. The project developed a generic solution that can be implemented in a number of commercial sectors, such as horticulture, building management and pollution/water management. The developed concept is tested using data relevant to the horticultural area of application. The system also addresses the main issues related to mobile monitoring, including real-time response, data integrity, solution cost, graphical presentation, and persistent storage capabilities of modern mobile devices. Four embedded databases based on J2ME have been investigated. Two of the four have been evaluated and analysed. The Insert function, Sequence Search, and Random Search of Perst List and RMS (Record Management System) databases have been tested. The size of the processed data was limited to 20,000 records when using the wireless toolkit simulator, and 11,000 records when using a mobile phone. Perst Lite reflects good performance and has out-performed RMS in all tests. User interface software such as J2ME Polish for mobile phones has been investigated. Custom J2ME class for graphical interface is developed. This provides the graphical presentation of the data collected from the sensors; including temperature, wind speed, wind direction, moisture, and leaf wetness. The graphical interface, bar charts, and line charts with trace ball for collected data have been designed and implemented. The embedded database performance and project performance have been investigated and analysed. The performances of Perst Lite and RMS are evaluated in terms of the insert, sequence search, and random search functions based on simulation and real devices. The record numbers vary from 1,000 to 20,000. The project performance contains data receiving and storage, and data presentation and configuration. The performance of data storage and configuration can be negated due to the running mode and the response time. Thus, data presenting performance is the key focus in this project. This performance was divided into the categories of initial, data search, data selection, and charting. The initial performance includes the initialisation of the project parameters, and the reaching of the welcome interface. Data search performance refers to the retrieval of the specified data from the embedded database, measured on 48 data points, which only can be presented on the mobile screen from the retrieved data. These four performance types are measured in thousands of record numbers, varying from 1,000 to 18,000 record numbers, with the retrieved data range varying from 1 day to 30 days.

The main focus of the work reported here is in the design of an intelligent condition monitoring system for diesel engines. Mechanical systems in general and diesel engines in particular can develop faults if operated for any length of time. Condition monitoring is a method by which the performance of a diesel engine can be maintained at a high level, ensuring both continuous availability and design-level efficiency. A key element in a condition monitoring program is to acquire sensor information from the engine, and use this information to assess the condition of the engine, with an emphasis on monitoring causes of engine failure or reduced efficiency. A Ford 70PS 4-stroke diesel engine has been instrumented with a range of sensors and interfaced to a PC in order to facilitate computer controlled data acquisition and data storage. Data was analyzed to evaluate the optimum use of sensors to identify faults and to develop an intelligent algorithm for the engine condition monitoring and fault detection, and in particular faults affecting the combustion process in the engine. In order to investigate the fault-symptom relationships, two synthetic faults were introduced to the engine. Fuel and inlet air shortage were selected as the faults for their direct relationship to the combustion process quality. As a subtask the manually operated hydraulic brake was adapted to allow automatic control to improve its performance. Two modes of controlling were designed for the developed automatic control of the hydraulic brake system. A robust mathematical diesel engine model has been developed which can be used to predict the engine parameters related to the combustion process in the diesel engine, was constructed from the basic relationships of the diesel engine using the minimum number of empirical equations. The system equations of a single cylinder engine were initially developed, from which the multi-cylinder diesel engine model was validated against experimental test data. The model was then tuned to improve the predicted engine parameters for better matching with the available engine type. The final four-cylinder diesel engine model was verified and the results show an accurate match with the experimental results. Neural networks and fuzzification were used to develop and validate the intelligent condition monitoring and fault diagnosis algorithm, in order to satisfy the requirements of on-line operation, i. e. reliability, easily trained, minimum hardware and software requirements. The development process used a number of different neural network architecture and training techniques. To increase the number of the parameters used for the engine condition evaluation, the Multi-Net technique was used to satisfy accurate and fast decision making. Two neural networks are designed to operate in parallel to accommodate the different sampling rate of the key parameters without interference and with reduced data processing time. The two neural networks were trained and validated using part of the measured data set that represents the engine operating range. Another set of data, not utilized within the training stage, has been applied for validation. The results of validation process indicate the successful prediction of the faults using the key measured parameters, as well as a fast data processing algorithm. One of the main outcomes of this study is the development of a new technique to measure cylinder pressure and fuel pressure through the measurement of the strain in the injector body. The main advantage of this technique is that, it does not require any intrusive modification to the engine which might affect the engine actual performance. The developed sensor was tested and used to measure the cylinder and fuel pressure to verify the fuel fault effect on the combustion process quality. Due to high sampling rate required, the developed condition monitoring and fault diagnosis algorithm does not utilize this signal to reduce the required computational resources for practical applications.

Today energy resources are becoming scarcer and therefore more valuable. In conjunction with the population growth over last century, the need for finding new, more efficient, and sustainable methods of agricultural cultivation and food production has become more critical. To facilitate this process, we are designing, building, and evaluating a system for precision agriculture which provides farmers with useful data about the soil, the water supply, and the general condition of their fields in a user friendly, easily accessible manner. Our system aims to make cultivation and irrigation more efficient as the farmer is able to make better informed decisions and thus save time and resources. The diversity of location and climatic effects upon agricultural cultivation, along with other environmental parameters over time makes the farmer’s decision-making process more complicated and requires additional empirical knowledge. Applying wireless sensor networks for monitoring environmental parameters and combining this information with a user-customized web service may enable farmers to exploit their knowledge in an efficient way in order to extract the best results from their agricultural cultivation. The system can scale based on each farmer’s demands and the resulting ensemble of collected information may represent a valuable resource for future use, in addition to its use for real-time decision making. The design of the precision agriculture system contains a prototype solution regarding the sensor platform and a customizable service that can be utilized in different ways and by several entities.Idag när energiresurser blir allt knappare och knappare blir de även mer värdefulla. I samband med befolkningstillväxten under förra århundradet har behovet av att hitta nya, mer effektiva och hållbara metoder inom jordbruket och livsmedelsproduktion blivit av allt större vikt. . För att underlätta denna process har vi designat, byggt och utvärderat ett system för precisionsjordbruk som ger bönder mer användbara data om jorden, vattenförsörjning och det allmänna tillståndet i sina områden på ett användarvänligt och lättillgängligt sätt. Vårt system syftar till att göra odling och bevattning effektivare då bonden kan fatta bättre underbyggda beslut och därmed spara tid och resurser. Mångfalden av läget och jordbrukets klimatpåverkan, tillsammans med andra miljöparametrar över tiden gör bondens beslutsprocess mer komplicerad än tidigare och kräver ytterligare empirisk kunskap. Att tillämpa trådlösa sensornätverk för övervakning av dessa parametrar och att presentera? denna information med en användarvänlig skräddarsydd webbtjänst kan göra det möjligt för jordbrukare att utnyttja på ett effektivt sätt nåde bästa resultaten från sitt jordbruk. Systemet kan skala utifrån varje bondes krav och den insamlade data kan utgöra en värdefull resurs för ett framtida jordbruk, utöver dess användning för dagens bondes beslut. Utformningen av systemet för precisionsjordbruk innehåller en prototyplösning avseende sensorplattformen och en anpassningsbar tjänst som kan användas på olika sätt och av flera enheter.

Full textAbstract:
Underlying the majority of remotely-sensed data analysis is the assumption that geographical phenomena, such as rivers, heather-moors and the dynamics associated with such objects, can be adequately detected and identified through the use of spectral and other visual information alone. There is a common misconception that any major deficiencies of quantitative analyses are "hardware problems": that by increasing the spectral, spatial, radiometric and temporal resolutions of sensors, geographical phenomena will be identified with similarly increasing accuracy and reliability. This, however, is an unrealistic viewpoint. This thesis has developed a prototype of an automated system based on the principle that by considering the "real-world" properties of the land, a more effective and robust analysis of its dynamic nature can ensue. SYMOLAC is an automated SYstem for MOnitoring LAnd Cover based upon theories of artificial intelligence. It has been developed within a specifically designed hybrid software environment called ETORA, an Environment for Task-Orientated Analysis. This prototype environment allows SYMOLAC to utilise disparate sources of spatial data, to reason with both quantitative and qualitative knowledge, to model disparate domain uncertainties, and to exploit the functionality of third-party software components. Unlike standard approaches, it allows an automated analysis to focus on each particular domain task and how it may best be performed with the available data, knowledge and software resources. The detection of forest felling and the subsequent update of the Land Cover of Scotland (1988) dataset forms the initial application of SYMOLAC. It is concluded that the system's approach is flexible, extensible and adaptable, and demonstrates one way in which satellite imagery can offer potential to the future monitoring of complex land cover change without the need for human intervention.

As the network was developed and popular, the application of remote monitoring system is more and more broad-spectrum. Not only the security system in our society is still deficient but the cost of private security service is expensive as well. Both of them could not be afforded by the common people. Now it can cost us few to achieve the aim by combining the image capture, and network technique together with operating in coordination of the analysis and the image processes. The real-time remote monitoring system, which combines image captures, image processes and network control is proposed in this thesis. Thereamong, We focused on the image captures and processes. According to the MSDN functions which were afforded by Microsoft and USB(Universal Serial Bus), we can use the digital camera or CCD ones to capture images. In the parts of image analysis and image process, we can compress and save the image/video files and act motion detection to give the alarms. When someone intrudes the areas we were monitored, the system will be set in motion and sent the e-mail to the users. Finally, we attached the image transmission trough internet to our system. Let the users observe the condition of monitoring system by browser without any limits.

Internet of things is a main trend of future development of information technology, especially, in the applications of disaster prevention for rainy and earthquake-prone areas. A pre-force ground anchor is usually used to prevent the landslide of a hillside as well as the steel cable to support the deck of drawbridge. To keep and monitor the force on a ground anchor and the stress of steel cable are very important. An annual inspection of the force is not enough to prevent the occurrence of disaster of landslide or drawbridge breaking. Hence, a real-time remote-monitoring system is necessary. In this work, a wireless sensor network that includes a local Zigbee network and a global system of mobile (GSM) communication is applied to remotely monitor status of drawbridge or hillside via the stress inspection. A load-cell sensor with a 24 bits analog-to-digital converter are used to measure the force or stress on the ground anchor of steel cable, respectively. The measured date is collected via a local wireless Zigbee network. The collected data is transmitted to a server through GSM communication for other applications. A demo system has been set up at Dona drawbridge of Maolin Kaohsiung of Taiwan. The technology developed in this work can also applied to other environment monitoring, family Care and health care

Railway Transportation is widely popular by many advanced countries and cities due to high convenience and reliable safety. Therefore railway line is continuously extended and constructed, meanwhile, Turnout system is widely applied and installed at intensive-transport station and maintenance depot, so as to enhance the capability of flexible and efficient train operation. Turnout is responsible for a required equipment of a running train transferring form original track to another appointed track. The functionality and safety of Turnout under a strict control and monitoring is absolutely necessary, especially high speed rail requires more high-level requirement of safety and reliability for Turnout specification. In case of wrong side failure (WSF) or malfunction, minor effect causes train operation delay and lose, the worst case possibly makes train derailed and terrible accident happened, especially in high speed train. A review of railway accident history in the world, the accident happened at Turnout area is common occurrence. Normally a Turnout requires the driving device, switch machine to achieve a moving process. By using connective rods with Turnout, switch machine push or pull the tongue rail of Turnout to reach a specified position and firmly lock, so as to the wheels of a running train can safely enter to Turnout area. In case that switch machine cannot successfully push or pull Turnout to specified position with required end detection signal, Turnout will be determined as a malfunction. For safety concern, any train is prohibited to enter or pass this Turnout without detection. In order to fulfill the high safety requirement of Turnout in railway system, the research approach, Turnout monitoring system adopts non-invasive proximity sensor, stress sensor and current sensor to monitor some critical parameters, including close side of tongue rail of Turnout, throwing and resistance force of Turnout and motor current of switch machine. To seek for enhancement of safety and reliability of Turnout operation, improving maintenance quality and efficiency. Before Turnout failure happened, to identify relevant irregular deviation or variety and indicate a warning for maintenance staff to early implement corrective adjustment or inspection. It can improve the present maintenance manner that Turnout status requires sight of inspection by maintenance staff in person at site of Turnout at maintenance period, to reduce maintenance cost of manpower and confirm that maintenance performance is fulfilled as expected. In duration of Turnout failure, help maintenance staff to accurately identify the failed point or symptom and accelerate troubleshooting efficiency to decrease the negative effect of train regular timetable of departure or arrival due to emergency Turnout handling.

Electricity is needed in everyday life, but once you start using many household appliances such as refrigerators, televisions, desktops, factory equipment, etc., they are rarely shut down. In order to prevent leakage and waste of electricity, our system can regularly record the power consumption of each power device, and calculate the power consumption at each time interval, and then display it on the chart, which can understand the power consumption of the appliance. By uploading data to your phone, users can view the usage of all devices installed with such devices at the same time. In this system, the control module is divided into signal processing and receiving module and signal processing and transmission module two sub-modules. The module includes a power measurement device and a Bluetooth module that can be mounted on a household appliance. The signal processing and transmission module can be plugged into an electrical outlet to detect changes in power consumption of the device plugged into the power outlet; the signal processing and reception module can transmit the measured data to the handset via Bluetooth to display power changes. The module installed on the socket side will periodically transfer the measured power change to the module on the receiving side via Bluetooth, and the receiving module will send and display power changes to the handset. Monitor the user can pass the phone to view the power changes. The signal processing and reception module is capable of calculating power variations and generating warnings when a particular device uses power for a period of time under normal circumstances so that the user can pay special attention to the power consumption of such a device.

The importance of the transportation system to a country can be just like that of the blood circulation system to the human body. Many countries have spent a great amount of annual budget for maintaining, improving, and enhancing their transportation systems. It was common in the past that hardware resources (e.g., roads and vehicles) were introduced in order to meet the rapidly increasing requests on transportation. However, the former almost always hardly catches up with the latter. Moreover, introducing hardware equipments could be inadequate for the areas with limited sizes and crowded people. Therefore, under present conditions how to increase the efficacy, safety, and comfortability of transportation systems with the help of currently available high technologies, such as computers, networks, communication, controls, and advance managements may become more practicable. Traffic monitoring systems collect such data as traffic flows, headways, road occupancies, average car speeds, driving directions and trajectories from main arteries and critical hinges. The collected data would be useful for traffic control centers to manage either manually or automatically traffic signals. Vehicle drivers will be able to plan in advance their routes before leaving for destinations based on the information delivered from traffic control centers. Long-term observed traffic data will provide valuable references for the personnels who maintain and construct roads as well as the researchers who would like to investigate the relationships among transportation equipments, driving behaviors, and accidents at important transit spots. Furthermore, some traffic surveillance systems can detect unusual events (e.g., collisions, breakdowns, and traffic law violations) and afterwards put on record the processes of the events. In the above, we only name a few applications regarding traffic monitoring systems. There are actually more to say with the systems. In this project, a prototype of traffic surveillance system is proposed. The details of implementing the system are described in depth. We mention the difficulties probably encountered during the development of the system and provide possible solutions to the difficulties as well.

With the fluctuation of global petroleum price and the nature resources are facing scarcity with increasing demands of power from industrial and household usage, the subject of Energy Saving and Carbon Reduction has become the top priority to the general public. In addition, the topic on how to utilize the limited resources and energies in a more efficient way has been the most important matter nowadays. General speaking, the energy monitoring system has been utilized mostly in the manufacturing plants and the public sectors, including hospitals and schools in order to achieve the purpose of regulating and reserving the expenses. However, this thesis stands from a different point of view that is commonly been overlooked in the past, which is the energy been used from households. The Home Power Monitoring System features a digitalized interface which monitors the usage of energy and providing instant information for end users to observe. This user interface is developed by Visual Basic 2005 and it includes a signal measurement module and a monitoring program controlled by a computer; it also uses wireless transmission for data analysis and communication. The hardware features STMicroelectronic’s chip as its core processor, and it utilizes RF315MHz to execute data transmission wirelessly. Meanwhile, the measuring terminal presents 4 groups of data including voltage, current, power factor and cumulative power that are calculated at a 60Hz of speed. The raw data will be averaged with phase difference, then recorded and being transmitted through the wireless module to the receiver. Once it is been received, the RS-232 interface transmits the data to computer for user to realize the actual electricity consumption in order to accomplish the purpose of energy monitoring and power saving.

Industrial equipment malfunction without warning often caused significant damage to the factory and even led to an industrial safety event. One of the important signs of equipment malfunction is the abnormal temperature rise. The main purpose of this thesis is to develop a multi-point remote temperature monitoring system using ZigBee wireless communication to deliver the latest temperature data of equipment to the host computer. The system uses platinum resistance thermometers as the temperature sensing components to measure the surface temperature of equipment. A voltage/temperature transformation circuit is developed to transform the measured voltage signal into a digital temperature signal. The digital temperature signal is then delivered to a ZigBee wireless communication module through a RS-485 to RS-232 interface. Then the digital temperature signal can be received to the host computer via received node ZigBee module. In the work, a graphical monitoring system will also be established in the host computer using Visual Basic software to create an easy use man-machine interface. Historical temperature records in the host computer can be inquired. IF the temperature of equipment exceeds the set alarm value, the alarm system will be activated. This thesis aims to achieve an automatic monitoring and meet the trend of modern industrial, which is warning in advance to prevent damage first.

The study proposes a new safe driving monitoring system. The system consists of the monitoring subsystem for movement of driver’s head and the monitoring subsystem for lane departure. It monitors whether the driver’s head and traffic lanes are in normal position. If either abnormal movement of driver’s head or departure of traffic lanes are detected, the system issues a warning signal to the driver immedeiately. In the monitoring subsystem for movement of driver’s head, the LED auxiliary device is adhered to the back cushion behind the driver’s head. The CMOS sensor is used to acquire frames including the region around the driver’s head. The acquired frame is analyzed by the proposed head movement monitoring algorithm. By monitoring the change of the LED region, the algorithm can detect the condition of abnormal head movement. The demonstration of software simulation on the test video indicates the subsystem can detect the abnormal movement of the driver’s head successfully. For hardware verification of the subsystem, the simulation result shows that the throughput can be higher than 15 fps with the hardware cost of 569 logic elements. It reveals that the proposed design achieves the requirement of real time processing. In the monitoring subsystem for lane departure, the CMOS sensor placed at the middle of upper side of windscreen acquires the frames including the road surface in front of the car. The acquired frames are analysed by the proposed lane departure monitoring algorithm. By monitoring the angles variation of marking lane, the algorithm can detect the condition of lane departure. The demonstrations of software simulation on six test videos from different environments indicate the subsystem can detect lane departure successfully. For hardware verification of the subsystem, the simulation results show that the throughput reaches 15 fps with the hardware cost of 43856 logic elements and memory cost of 842496 bit. It reveals that the proposed design fulfils the requirement of real applications.

Elevator surveillance systems currently on the market are mostly closed system. They are non-IP-based, expensive, uneasy to use, and could not be integrated with existing computer network. On the other hand, IP-based camera for simple video communication could not do real-time surveillance when security problem exists.. Even real-time detection by people, we could not promise thers is no human negligence which cause the situation not remedied. Our proposed intelligent video processing technology using Android library could read real-time capture image from camera, encode and transmit it. Before transmission, we could detect the image if any changes or not. If it is static, we will not transmit it to save the network traffic. With OpenCV library, we can do many image processing, like people recognition to archive people counting, to know the elevator is overload or not, or detect people are doing dangerous actions or not. Using computer automation software, we could resolve traditional monitoring which requires a lot of manpower. According to the experiments, we found the net flow of Spydroid almost in 200KB/S, no matter we set the different resolution or FPS, not like our system, from 55KB/S to 470KB/S, have a significant change. We can reduce the network flow when there is no change in video, down to 0KB/S, but we didn’t find any mechanism in Spydroid. We also test muti-client cause problem to system or not, and confirm our system still work.

In recent years, the concept of Internet arised, and the Internet devices gradually increased. Provided by the Economic Daily, this year has reached 30 billion devices with the functions of the Internet. In the near future, 50 billion or even hundreds of billions will be needed. The demanded number is considerable. When the Internet of Things comes, everything is not just connected to the Internet only, it is imperative to equipped with remote monitoring systems and provide users with experience in the design of the service. People face the pain every day. For example, when people come to the toilet, suddenly found the tissue run out, or the toilet all in the use of the dilemma; when the toilet is finished, press the hand sanitizer many times, but can not press the hand wash; toilet puddle or smelly smell and so on. How to solve the above problem, and in the event of immediate treatment, so that people are more convenient and comfortable are what we concerned in this thesis. This thesis carries out the analysis of the toilet scene, summed up must to be designed and value-added service design, design thinking planning, in solving the problem, we must also consider the cost and user experience services. Using circuit design technology, sensor integration technology, printed circuit board technology, 3D modeling and printing technology, web platform development and mobile device series technology to develop, in order to achieve hardware and cloud services in series. If the instantaneous detection of consumables is about to run out, it will automatically start the notification mechanism, and can be monitored on the cloud platform at any time. After this field of study, the toilet information service system becomes more immediate, intelligent, systematic and informative.
