Full textThe domain below the surface in maritime security is hard to monitor with conventional methods, due to the often very noisy environment. In conventional methods the measurements are thresholded in order to distinguish potential targets. This is not always a feasible way of treating measurements. In this thesis a system based on raw measurements, that are not thresholded, is presented in order to track and classify divers with an active sonar. With this system it is possible to detect and track weak targets, even with a signal to noise ratio that often goes below 0 dB.
The system in this thesis can be divided into three parts: the processing of measurements, the association of measurements to targets and the classification of targets. The processing of measurements is based on a particle filter using Track Before Detect (TBD). Two algorithms for association of measurements, Joint Probabilistic Data Association (JPDA) and Highest Probability Data Association (HPDA), have been implemented. The classification of targets is done using an assumed novel approach. The system is evaluated by doing simulations with approximately 8 hours of recorded data, where divers are present at nine different times. The simulations are done a number of times to catch The classification rate is high and the false alarm rate is low.
Undervattensdomänen är svår att övervaka i marina säkerhetssystem med sedvanliga metoder, på grund av den brusiga miljön. I traditionella metoder trösklas mätningarna för att urskilja potentiella mål. Detta är inte alltid ett godtagbart sätt att behandla mätningar på. I den här rapporten presenteras ett system baserat på behandling av rå mätdata, som inte trösklas, för att spåra och klassificera dykare med en aktiv sonar. Med detta system är det möjligt att detektera och spåra svaga mål, trots att signal till brus förhållandet ofta går under 0 dB.
Systemet i den här rapporten kan delas upp i tre delar: behandling av mätningar, association av mätningar till mål samt klassificering av mål. Behandlingen av mätningarna görs med ett partikelfilter som använder Track Before Detect (TBD). Två algoritmer för associering av mätningar, Joint Probabilistic Data Association (JPDA) och Highest Probability Data Association (HPDA), har implementerats. Klassificeringen av mål görs med en egenutvecklad metod som inte har hittats i existerande dokumentation. Systemet utvärderas genom att simuleringar görs på ungefär 8 timmar inspelad data, där dykare är närvarande vid nio olika tillfällen. Simuleringarna görs ett antal gånger för att fånga upp stokastiska beteenden. Andelen lyckade klassificeringar är hög och andelen falsklarm är låg.

With the increasing awareness of sustainable and green building, more and more people are concerned with the efficiency of energy use at home and at work. A solar tracking skylight illumination system, which enables us to conserve energy by producing increased interior light levels for a longer duration than normally possible, can fit to the above need and have widen been used in the indoor illumination gradually. Tracking sunlight and guide the light indoor as a source of illumination is also a way of energy saving. Daylight catching system, simply put, the light is sunlight, a part of interior when the illumination used; another part of the light is converted to electricity for use. In the self-sufficiency is no need for other power supply, to achieve zero CO2 emissions, a green energy product. Purpose of this study to implement is a way to develop a daylight catching system for illumination. An experimentally investigation is conducted to explore the dynamic illuminative performance of daylight catching system. The daylight catching system drives the sun tracking mechanism by the database of sun-path which is burned in microcontroller. The system will keep working without weather condition. The results show that (1) the triple reflected sunlight can provide sufficient 400~700 Lux to the room from AM 7:00 to PM17:00 without artificial light. (2) The system can be installed not only on the roof of the building, but also on other floors. Mirrors with high reflectivity are used to guide sunlight into the room. So the system can decrease the power consumption of indoor illumination in daytime. (3) With active tracking system, the mechanism can have the best accuracy immediately. The error angle of the mechanism can be less than 2∘. (4)The performance of the system can be seemed as a 27W lamp. The sunshine duration in Taipei (1999~2008) is 1431 hours per year. It means that the system can save 38 kWh per year.

The purpose of this thesis is to design an active solar panel dual-axis suntracking system with maximum power point tracking fuzzy controller. The tracking system tracks the maximum solar power point no matter what the environmental condition it is and orients the solar panel toward the Sun to enhance the efficiency of thephotovoltaic generation system. First, the operating points of the PV panel are adjusted by a boost converter. The PV voltage and current are measured in real time, and used to estimate the system parameters in the power-voltage polynomial equation and to identify the maximum power. Meanwhile, four light sensors sense one current respectively, which represent the illumination at the time. Inputting the maximum power and four currents to the two fuzzy controllers for dual-axis tracking system, the rotated angles will be got to make the mechanism rotate to the appropriate position. Through the sun tracking method, the PV panel will face the Sun directly at all time. Finally, the simulation results using Matlab verify the effectiveness of the proposed controller.

Abstract This article is to design, through NI LabVIEW software, the controlling dual-axis solar tracking platform, to enable the platform to automatically track the sun so as to obtain the utmost sunlight energy. Based on the earth orbiting from the sun formula, it will automatically calculate the sun rays to the local horizontal elevation and azimuth information, feed into the tracking platform for control systems, and command the control systems to present the required elevation and azimuth patterns. In the research project, we will design a dual-axis to the push-pull control tracking platform and use the linear actuator (Linear Actuator) to push solar panels, which will result in angle change. The Data Acquisition (DAQ) interface will collect displacement volume; through the LabVIEW control program, it will calculate the driving command, send from the DAQ interface to the linear actuator driver (Driver), impel the platform mechanism, and form an automatic control device in order to achieve the purpose of automatic tracking. This system has been verified through actual operation. The overall structure of hardware and software is feasible. Before the tracking system going to work, we implement a set of 2 axis Accelerometer Module (ADXL 203EB) to control and monitor the solar panel leveling in order to establish the platform initial conditions. Key Words: LabVIEW, ON-OFF Driver, Linear Actuator, Data Acquisition, Solar Tracker, Push-Pull Control Tracking Platform, 2 Axis Accelerometer

This paper is to develop a real-time sun tracking system with MPPT to improve the electrical efficiency of PV. In the system, the time driven biaxial tracking system is made with PIC16F883 single-chip. The main purpose of the time driven biaxial tracking system is to increase the electrical efficiency of the traditional fixed PV. The core reason why PIC single chip is used as the time driven biaxial tracking system is that the position and angle of the solar light can be calculated quickly and accurately. It is for the purpose of PV can get gabundant sunshine. At the same time, the MPPT controller is used to match the internal resistance of PV to adjust the terminal voltage, so that PV can get good electrical efficiency under different accumulative insolation and temperature conditions. The results of the experiments in this paper will be compared and analyzed.
