Abstract: Wireless Sensor Network is a a brand new technology of information acquisition and processing. Compared with the various technologies applied in the current transportation monitoring system, Wireless Sensor Network has the advantages of self-organizing and distribution. In this thesis we have proposed the design of distributed self-organizing highway monitoring system based on Wireless Sensor Network, and we have constructed Safety Distance Monitoring Model between vehicles by combining with concrete datas such as road visibility, traffic flow,etc. The model can exploit the advantage of WSN to calculate approriate safe driving distance between vehicles by referring to road visibility, traffic flow and others at any time. When the distance between driving cars is smaller than the safety distance, the drivers would be warned by menas of car radio, car GPS, RFID and other radio device to avoid happening of traffic accidents.

Abstract: An engineering machine wireless control system is researched based on a diggings milling collection machine. The system consists of PLC, communications module, relays, touch screen, router and long-distance terminal. The ideas of PLC state of self-sustaining when host dropped, wireless control and local control redundancy, and control instructions prioritization are proposed to achieve the reliable operation of the system. The system with local control and wireless control has been applied on the sand milling collection machine and the wireless remote control of all operations has been realized with no instruction lost and misused. A mining engineering requires that the sand with the mine in the earth’s surface of about 2~5cm depth should be collected. Also, in order to realize the accurate collection to reduce the subsequent processing cost, it demands that the thick precision of the collection should be controlled within ±5mm. Considering that the milling collection is suitable for work of large-area sand collection and easier to meet the demand of the accurate control of the depth, the sand milling collection machine is researched. This machine is equipped with the milling collection unit and depth control system. It is able to conduct the sand collection experiment under the field condition.

Abstract: This paper mainly introduces a PID controller, which is optimized by an improved BP algorithm, and discusses the analysis method of it. It states a way to dynamically adjust the learning rate and the momentum factor through the variety of the input and output of the PID controller to realize an intelligent control. And it connects this control method with the control of the hot winds of the gas in bar furnace of a steel plant to realize a closed-loop control and solve the problems such as the wave of the gas pressure and the insufficiency of combustion. According to the practice, the fluctuation of gas pressure is restricted within 5%, which means that this control method could largely improve the precision of furnace control and further more raise the economic and social benefits.

Abstract: Safety and Reliability are fundamental and challenging problems in the Battery Management System (BMS). To maximize the lifetime of battery, the process of charge and discharge must have to consider consensus. This paper provides a theoretical framework for analysis of consensus control with an emphasis on robustness due to the battery differentiation. A hybrid model is constructed to illustrate the process of updating energy state and topology structure. Based on the model, a consensus algorithm for BMS is proposed. It’s useful for evaluating optimal utilization of battery management at design phase. Related analysis reveals that the energy state of discharge process in battery modules converges to balance. A prototype of simulation was developed according to the constructed model. Simulations results are presented that demonstrate the effects on the speed of consensus algorithms and cooperative control of battery modules.

Abstract: The research & development of intelligentialized and automated Advanced-Surface Movement Guide and Control System (A-SMGCS) is a new trend for guaranteeing the security and high efficiency of surface traffic control in the airport. Aimed at the guidance module in A-SMGCS, this paper studied the algorithm which was used for intelligently creating aircraft guided route on the ground. Using Visual C as the development platform, it introduced the design thought and the procedure of the program for realizing this algorithm. Then it has run the program and achieved the sequence of coordinated points of guided route. Comparing with the planning guided route, it analyzed the graphical results of the program. The simulation proves that the original guided route in the plan could be accurately created by this program. It also shows that this algorithm could provide some thoughts for development of A-SMGCS.
