基于ARM9的矿井人员信息采集与识别系统的研究

Radio frequency identification study is based on the characteristics of the frequency, which is a identify technology of data by the way of radio frequency for data communication and exchange . Mine personnel information collect and identify by radio frequency identification technology, which achieve development in the power-line transmission of data spread spectrum digital transmission system. The main application of electromagnetic energy transmission and modulation of RFID technology to analyze system-coupled with the near-field radiation is far field and carry out the communications system at same time. On this basis, it design a set of the ARM9-based embedded personnel mine information collection and identification devices, which of hardware by the micro-structure of the mobile radio-frequency card, detection and information gathering stations and the main control module composition by ARM9 ,and which of system software into firmware Program modules radiofrequency card drivers and communications sub-module, and so on.
