A Orientation System Of Mine Personnel Based NRF401

For adapting request of safe production of coal mine, we design a kind of mine personnel orientation system based radio frequency identification.The system has the function stability, the personnel identifies a rate high, the mistake code rate is small, the usage convenience, the cost is low etc. advantage,and has very big realistic meaning.This text first introduces a radio frequency identification of concept, briefly says a radio frequency identification of the development process and the work principle. Then combining the condition of our country mine work presently, we expatiate the important meaning of mine personnel radio frequency identification orientation system and the urgency to design it and we introduce the main research work of myself: mine personnel data to exchange the system hardware electric circuit system design (include radio frequency card, radio frequency to identify reading base,the long distance data transfers interface),the correspondence agreement establishment and related singlechip procedure compilation. database design, inquiry way compilation, the radio frequency card and the mine reading base of data exchange of confirm mechanism, we put forward own innovation and carry out my design in actual work.Secondly, we introduce the work block diagram of the mine personnel orientation system, analyze the main function of the system, and discuss comparing various data checkout mechanism, modulate manner, data re-send mechanism, the in common use chip and the long distance of the data to deliver etc problem, we get system to choose a conclusion at last.Thirdly, we analyze the radio frequency card, mine personnel the radio frequency reading base and data transfers interface from the hardware design in detail, and carry on introduction the key chip nRF401 in the electric circuit.Fourthly, we introduce the correspondence agreement of mine personnel orientation system, analyze the design principle and block diagram of radio frequency card, mine personnel radio frequency base radio frequency cell, and the long distance data transfers interface etc 3 independence software procedures.At last, we sum up the work foreground and the shortage in the work and put forward my improvement opinion.
