摘要
通过对国内外列车定位与跟踪系统的现状和发展以及目前最先进的定位技术进行分析,结合客运专线对列车定位与跟踪的需求,提出了基于SAW RFID的列车跟踪与定位系统,可实现在隧道或遮蔽环境下实时、接近连续式的列车定位与跟踪,最后利用查询-应答器测试标准进行了相应的仿真分析。该系统具有建设和维修成本低,抗干扰能力强,具备防滑校正能力,结合轮轴测速传感器的连续式速度测量,可实现高精度的列车定位,且能满足运行速度为300 km/h的高速列车对定位精度要求。
Through the analysis on the current situation and development process as well as the most advanced technology of domestic and international train locating and tracking systems,in combination with the demands of passenger-dedicated line on train locating and tracking,this paper proposed a SAW RFID-based train locating and tracking system which can realize real-time and almost continuous train locating and tracking in the tunnel or covered environment,and then made the corresponding simulation analysis using the inquiry-responder testing standard.This system costs low on construction and maintenance,having stronger anti-interference capability with anti-sliding and correction capability.By this system,combined with the continuous velocity measurement by wheel speed sensor,train locating with high accuracy can be achieved,and the requirements on locating accuracy of high speed train under a speed of 300 km/h can also be satisfied.
