This paper discusses a Federal Aviation Administration (FAA) manned simulation study that investigated the effects of Controller-to-Pilot Data Link (datalink) on crew communications. Professional pilots participated in high fidelity simulation tests where crews received Air Traffic Controller (ATC) messages through the datalink. The results were compared to a similar study conducted where crews only communicated by radio to controllers. Results demonstrate that the nature of crew communications within the flight deck do change because of datalink. Unlike in the past where crews became aware of ATC communications at the same time through their headsets, new communication types are now needed due to the shift from ATC radio communications to ATC datalink messages. Thus flight crews must keep each other aware of information passed through the datalink. The frequency of communication was found to be significantly different depending on the location of the datalink on the flight deck. In addition, datalink crews experienced significantly less ATC radio transmissions as expected; however, the within crew communication related to datalink increased. When within crew datalink communication and the ATC radio communication are combined, one finds that ATC related communication is significantly higher in datalink crews as compared to traditional radio crews. This study illustrates the need to fully evaluate the impact new technology has on flight crews and their communication process.

This paper designs a hand-held radio frequency identification and localization terminal based on ARM Cortex-M3 processor and active radio frequency tags based on 8051 processor. This terminal uses STM32F103VET6 as its master controller, these tags use STC12C2052AD as their master controller. They all use Nordic nRF905 as their radio frequency identification module. The system works in 433M/868M/915MHz ISM UHF band and can read, write and locate radio frequency tags within 50m indoors. The actual measurement of active radio frequency tags shows that this terminal is highly stable and comparable in 433M/868M/915M ultra-high frequency radio identification and localization. The test results of this system are also analyzed and presented.

A smart material actuator is required for a smart structure having multifunctional performance. Among the smart material actuators, piezoelectric actuator is known for its excellent large force generation in broad bandwidth in a compact size. However it needs relatively large actuation voltage requiring a bulky hardware system. This study is mainly concerned to develop a self-powered miniaturized piezoelectric actuator driver (MIPAD) controlled by a radio controller for small sized piezoelectric smart structures. It can receive command from other microprocessors or a remote radio controller. We designed a real hardware and it demonstrated good performances even though the driving system was very small. The MIPAD is expected to minimize the weight and size of the piezoelectric actuator system and it can be easily embedded into mobile smart structures.

SUMMARYThis paper deals with the motion prediction and control of the macro–micro parallel manipulator system for a 500-m-aperture spherical radio telescope (FAST). Firstly, based on principles of parallel mechanism, a decoupled tracking and prediction algorithm to predict the position and orientation of the movable macro parallel manipulator is presented in this paper. Then, taken as the upper layer supervisory controller in the joint space of the micro parallel manipulator, the adaptive interaction PID controller utilizing the adaptive interaction algorithm to adjust the parameters of a canonical PID controller is discussed. In addition, the digital servo filters with feedforward are employed in the linear actuators as the lower layer controllers. Experimental results of a one-tenth scale FAST field model validate the effectiveness of the supervisory controller and the motion prediction algorithm.

The changing schedule of automation radio broadcasting controlled by programmable logic controller, PLC [1] and the master clock [2] is time in second is required to execute the PLC program for every changing of the schedule program. The ideology of silence of sound signal (Audio Mute) is used when each program ends instead using the master clock to execute the PLC program for changing the schedule radio program. The application of audio mute for changing new schedule when each program ends can be compared with the using the master clock controlling the PLC will be also minimum deviation of the time that will impact on automation radio broadcasting.

In a distributed cognitive radio (CR) sensor network, transmission and reception on vacant channels require cognitive radio nodes to achieve rendezvous. Because of the lack of adequate assistance from the network environment, such as the central controller and other nodes, assisted rendezvous for distributed CR is inefficient in a dynamic network. As a result, non-assisted blind rendezvous, which is unaware of its counterpart node, has recently led to a lot of interest in the research arena. In this paper, we study a channel rendezvous method based on prime number theory and propose a new multi-radio-based technique for non-assisted rendezvous with the blind and heterogeneous condition. The required time and the optimal number of radios for the guaranteed rendezvous are calculated using probability-based measurement. Analytical expressions for probabilistic guaranteed rendezvous conditions are derived and verified by Monte Carlo simulation. In addition, the maximum time to rendezvous (MTTR) is derived in closed form using statistical and probabilistic analysis. Under different channel conditions, our proposed solution leads to a substantial time reduction for guaranteed rendezvous. For the sake of over-performance of our proposed system, the simulation outcome is compared to a recently proposed heterogeneous and blind rendezvous method. The Matlab simulation results show that our proposed system’s MTTR gains range from 11% to over 95% for various parametric values of the system model.

As one of the key technologies of Honeywell, the aeronautical radio incorporated (ARINC) 659 bus is popular in current space-borne computers. However, Honeywell does not design ARINC 659 bus controller separately, and there are only a few papers about FPGA-based ARINC 659 bus controllers. Accordingly, to promote the extremely high performance needs of space-borne computers, this paper designs an ARINC 659 bus controller chip which integrates two independent bus interface units (BIUs), one 8-bit MCU, and several peripheral interfaces (i.e., UART, SPI, and I2C). Because the two BIUs are identical and mutually checked, the symmetry problem is emphatically dealt with in the design of this bus controller, and effective timing convergence is realized, which makes the bus controller work reliably and stably. In addition, due to the circuit’s large scale, design for testability (DFT) is also considered. Accordingly, on-chip clock (OCC) and scanning compression test technique are used to realize the at-speed test and shorten the test time, respectively.

Unmanned aerial vehicle (UAV) networks have a wide range of applications, such as in the Internet of Things (IoT), 5G communications, and so forth. However, the communications between UAVs and UAVs to ground control stations mainly use radio channels, and therefore these communications are vulnerable to cyberattacks. With the advent of software-defined radio (SDR), smart attacks that can flexibly select attack strategies according to the defender’s state information are gradually attracting the attention of researchers and potential attackers of UAV networks. The smart attack can even induce the defender to take a specific defense strategy, causing even greater damage. Inspired by symmetrical thinking, a solution using a software-defined network (SDN) to combat software-defined radio was proposed. We propose a network architecture which uses dual controllers, including a UAV flight controller and SDN controller, to achieve collaborative decision-making. Built on the top of the SDN, the state information of the whole network converges quickly and is fitted to an environment model used to develop an improved Dyna-Q-based reinforcement learning algorithm. The improved algorithm integrates the power allocation and track planning of UAVs into a unified action space. The simulation data showed that the proposed communication solution can effectively avoid smart jamming attacks and has faster learning efficiency and higher convergence performance than the compared algorithms.

Traffic lights play such important role in traffic management to control the traffic on the road. Situation at traffic light area is getting worse especially in the event of emergency cases. During traffic congestion, it is difficult for emergency vehicle to cross the road which involves many junctions. This situation leads to unsafe conditions which may cause accident. An Automatic Traffic Light Controller for Emergency Vehicle is designed and developed to help emergency vehicle crossing the road at traffic light junction during emergency situation. This project used Peripheral Interface Controller (PIC) to program a priority-based traffic light controller for emergency vehicle. During emergency cases, emergency vehicle like ambulance can trigger the traffic light signal to change from red to green in order to make clearance for its path automatically. Using Radio Frequency (RF) the traffic light operation will turn back to normal when the ambulance finishes crossing the road. Result showed the design is capable to response within the range of 55 meters. This project was successfully designed, implemented and tested.

There is a rapid growth of mobile users so there are developing more number of features by a service provider to support more number of mobile users. The Common Public Radio Interface (CPRI) is an interface between the Radio Equipment Controller (REC) and Radio Equipment (RE) to support more number of users. This simplifies the overall architecture of radio base station. The radio base station is centralized and the radio heads are distributed in the environment. This radio heads supports the more number of users. The main aim of CPRI is to divide the packets into number of frames. The radio frame is divided into the hyper frames and this hyper frame is divided into the number of basic frame in which each basic frame is supported up to 16 words totally it supports up to 6,144 megabytes per second.

SUMMARYIn medical interventional procedures such as brachytherapy, biopsy and radio-frequency ablation, precise tracking through the preplanned desired trajectory is very essential. This important requirement is critical due to two major reasons: anatomical obstacle avoidance and accurate targeting for avoiding undesired radioactive dose exposure or damage to neighboring tissue and critical organs. Therefore, a precise control of the needling device in the unstructured environment in the presence of external disturbance is required to achieve accurate target reaching in clinical applications. In this paper, a shape memory alloy actuated active flexible needle controlled by an adaptive sliding mode controller is presented. The trajectory tracking performance of the needle is tested while having its actual movement in an artificial tissue phantom by giving various input reference trajectories such as multi-step and sinusoidal. Performance of the adaptive sliding mode controller is compared with that of the proportional, integral and derivative controller and is proved to be the effective method in the presence of the external disturbances.

As the environment of cognitive vehicular and maritime networks is extremely dynamic, these networks suffer with a long delay because of intermittent links while providing services for different applications. To this end, here we introduce the integration of cognitive vehicular and maritime networks to design a coastal smart city by utilizing software-defined networking, network function virtualization, and fog computing under the same infrastructure. This novel integrated cognitive coastal city fulfills the demand of each application user in a hybrid environment with a quicker response time. The idea is to combine vehicular and maritime communications to meet different user demands. Different virtual networks are launched by network function virtualization, and are managed and controlled by a software-defined networking controller. From the integration of software-defined networking, network function virtualization, and fog computing, both vehicular and marine users are provided with stable paths to meet each application’s demands.

An electrical device that transforms the electricity into the waves of radio and vice versa is termed the antenna. Its main deployment is in the transmitter and receiver of the antenna. While transmission, the transmitter of radio at the extremities of the antenna furnishes the electricity which oscillates at the frequency of radio wave and energy is released as current as em waves. Some of the voltage is formed from the em wave that is invaded at the point of receiving to amplify the receiver. This study focuses on the analysis of the satellite system to aid in mobile antenna tracking. It also examines the techniques for fuzzy control which make up traditional networks that are used. Initially, a basic idea of tracking loops with stabilized antennas was suggested in light of the requirement for the margin of phase and bandwidth. If the gain of the track is reduced due to changes in attributes and throughput, it will be reduced. In addition, fuzzy regulators and PID constituents are used to enhance the loop. The results indicate that the higher and lower antenna tracking gains within the loop were the best fit and the loop's fluctuations are reduced. A controller based on fuzzy logic can be most efficient due to its simplicity and robustness. It is also discovered that fuzzy logic controllers are evaluated by their behavior in relation. This paper presents an evaluation of the controllers in fuzzy logic, which is based on its integration with conventional controllers. There are three gains in PID's regulator PID and every gain can be used to control the variables of inputs and outcomes. The effects of the responses were analyzed and were compared. The commonality was discovered in the results according to the increase in time for II/6 and II/3 based on PID's regulator PID stability, it can be improved by this system, and there is a reduction in the duration of stability. Furthermore, the period of stability may be reduced through the fusion of PID and fuzzy. The effectiveness of the system could be enhanced by the implementation of the neural network. It is also possible to design the two types of control that could be used to control the proposed solid platform.

We report the first time-synchronized protocol stack running on a crystal-free device. We use an early prototype of the Single-Chip micro Mote, SCμM, a single-chip 2 × 3 mm2 mote-on-a-chip, which features an ARM Cortex-M0 micro-controller and an IEEE802.15.4 radio. This prototype consists of an FPGA version of the micro-controller, connected to the SCμM chip which implements the radio front-end. We port OpenWSN, a reference implementation of a synchronized protocol stack, onto SCμM. The challenge is that SCμM has only on-chip oscillators, with no absolute time reference such as a crystal. We use two calibration steps – receiving packets via the on-chip optical receiver and RF transceiver – to initially calibrate the oscillators on SCμM so that it can send frames to an off-the-shelf IEEE802.15.4 radio. We then use a digital trimming compensation algorithm based on tick skipping to turn a 567 ppm apparent drift into a 10 ppm drift. This allows us to run a full-featured standards-compliant 6TiSCH network between one SCμM and one OpenMote. This is a step towards realizing the smart dust vision of ultra-small and cheap ubiquitous wireless devices.

Bluetooth may be an inaccessible development standard utilized for exchanging data between settled and flexible contraptions over brief divisions utilizing UHF radio waves within the mechanical, coherent, and restorative radio bunches, from 2.402GHz to 2.480 GHz. PCM codec is an A/D interface for speech signals. The Bluetooth center framework underpins co-ordinate transport of application information that’s isochronous and of a consistent rate (either bit-rate or frame-rate for pre-framed information) employing an SCO or ESCO consistent joins. These coherent joins save physical channel transfer speed and give a consistent rate of transport bolted to the piconet clock. The codec interface block is used to interface an external PCM (8KHz voice data) or a stereo codec with the baseband controller for the direct transfer of voice data on isochronous links to external CODEC. Bluetooth baseband supports two CODEC interface protocols 1) for audio links it is the PCM interface and 2) for mono/stereo music data from audio codec it uses the IIS interface. This enables the source of isochronous data to be directly interfaced to the baseband controller if it is not required to be processed by firmware. It also provides the host access path where the source of isochronous data will be any application running on the host and data is written and read directly into baseband SCO/ESCO FIFOs from firmware. In this paper, PCM is verified in the Cadence tool and simulated images are shown.

The objective of this study was to examine the potential benefits for air traffic controllers from the use of automated weather advisories. In a part-task simulation, we used a weather support tool called Automatic Identification of Risky Weather Objects in Line of Flight (AIRWOLF) that (a) detects conflicts between aircraft and hazardous weather, (b) alerts the controller, and (c) generates automatic weather advisories. During the simulation, air traffic control (ATC) subject matter experts responded to AIRWOLF alerts and either provided weather advisories to pilots via radio in two main conditions or provided data link communication in a third control condition. Automated advisories (a) eliminate the need for a manual production of weather advisories; (b) reduce the production time, voice duration, and overall advisory duration; and (c) reduce the cognitive workload associated with the dissemination of weather advisories. The results showed that the AIRWOLF tool could support air traffic controller weather avoidance actions and provide accurate and timely weather advisories to pilots. The weather advisory tool could support en route controllers for the safe, efficient, and strategic efforts required to handle adverse weather conditions in the en route environment.

Wheeled robots are often utilized for various remote sensing and telerobotic applications because of their ability to navigate through dynamic environments, mostly under the partial control of a human operator. To make these robots capable to traverse through terrains of rough and uneven topography, their driving mechanisms and controllers must be very efficient at producing and controlling large mechanical power with great precision in real-time, however small the robot may be. This paper discusses an approach for designing a quad-wheeled robot, which is wirelessly controlled with a personal computer (PC) by medium-range radio frequency (RF) transceiver, to navigate through unpaved paths with little or no difficulty. An efficient servo-controlled Ackerman steering mechanism and a high-torque driving power-train were developed. The robot’s controller is programmed to receive and respond to RF control signals from the PC to perform the desired motions. The dynamics of the robot’s drivetrain is modeled and analyzed on MATLAB to predict its performances. The robot was tested on various topographies to determine its physical capabilities. Results show that the robot is capable of non-holonomically constrained motions on rough and uneven terrains.

Manual monitoring consumes more time, man power and shows inaccurate results. So, automation is the solution to cover the problems stated. Barcode and RFID are two different forms of automated technology that are used for reading and collecting data. The RFID (Radio Frequency Identification) technology is a well-known wireless application for traceability, logistics and access control. The RFID controller is constructed in to demonstrate access control through the use of low-frequency RFID tags. These tags contain identification number which is read by the reader, sent to a database where it is compared with stored values. It works on the principle that If the tag’s identification number is in the system database, it gives access. If the data is not in the system database, it doesn’t give access. To implement these various blocks, include RFID transmitter, RFID receiver, Baud clock generator, Database are designed. The RFID Controller is designed using Verilog HDL in Xilinx ISE tool.

The purpose of this paper is to synthesize an algorithm for coherent digital demodulation of non-uniformly distributed radio signals with absolute two-position phase shift keying, which has a small computational complexity, and to develop a miniature low-power demodulator on its basis. The relevance of the study is determined by the absence of similar devices in the Russian radio electronic market. The algorithm is based on digital phase-locked-loop frequency control. Its basic idea is to retain the optimal amplitude ratio between the phase quadrature of the received signal using a proportional-integral- differential controller. A digital device with the stated technical characteristics was obtained as a result of the study.
