Radio Frequency Identification Technology In The Mine Monitoring And Positioning Systems

RFID(Radio Frequency Identification)------The radio frequency technologyhas already been accepted as one of ten important technologies for this century universally, and also considered as the information standardization foundation which can realize gathering and process information fast, real-time and accurately. It has been widespread used in many fields such as the production, the retail sales, the class, the transportation, the mine and so on, which requests check without touch to get and switch data.On the basis of vast collecting the use situation of RFID and considering the status on the security manage of the mine, this thesis studies the application of RFID in the mine monitoring and localization system. With this technology and the modern computer communication, this system can realize the miner's localization, the mine vehicles management, the gas density gathering, the region management and urgent event processing and so on, and then the gathered information will be transmitted to the ground monitoring center through the CAN line promptly and effectively. So the mine departments and leaders can get the correlative circus of the mine easily, providing them with the important basis for the surveillance, the decision-making. Thus the system will promote the safety in production and the management efficiency.Firstly, this article introduces the status on the security manage of the mine and gives construction, function request and the technical parameter of the mine localization system, in view of the especial environment of the mine. Emphatically make the fundamental research to the radio frequency identification technology. Then it discusses elaborated the data gathering station and identification card with emphasis about the composition principle, the device choice and the hardware design process and the procedure of the system. Finally it discusses the debugging and anti-jamming measure of system.The innovation of the thesis is that it integrates the technology of RFID, the communication and the CAN to realize the monitoring and localization of the mine. With this system we may not only realize the function of monitoring and localization to the mine, moreover it has characteristics of strong extension and flexibly in use. For example, we can make different revision about the MCU according to the actual need, or download different procedure to different system. The hardware module of the system also may be expanded according to need to realize the function of sound and the short message. It is no problem to design other RFID system on the basis of this system. Such as the highway charge vehicle carries the RFID system, electronic security installment situation and so on.
