基于RFID的铁路巡检人员定位系统研究

Research on railway patrol personnel positioning system based on RFID

分析当前铁路列车巡检人员现状及发展趋势,设计了一种基于RFID技术的铁路列车检修人员定位装置。系统以STM32F103C8T6为控制核心,利用型号为nRF24LE1的RFID无限射频芯片进行巡检人员电子标签信息的收发,主控模块根据TOA(Time of Arriving)定位算法计算出标签的位置信息,利用均值滤波算法进行位置信息的校正处理,采用无线通信GPRS模块将巡检人员的位置信息实时传送到调度中心。该系统可实现完整的巡检人员智能定位,有效提升铁路列车运维效率。

This paper analyzes the current situation and development trend of railway train inspection personnel,and designs a positioning device for railway train maintenance personnel based on RFID(Radio Frequency Identification).The system takes STM32F103C8T6 as the control core and uses the RFID infinite RF chip of nRF24LE1 to send and receive the electronic tag information of patrol personnel.The main control module calculates the tag position information according to the TOA positioning algorithm,uses the mean filtering algorithm to correct the position information,and uses the wireless communication GPRS module to transmit the position information of patrol personnel to the dispatching center in real time.The system can realize the complete intelligent positioning of patrol inspectors and effectively improve the efficiency of railway train operation and maintenance.
