为了解决高速铁路基础设施动态检测中检测数据的精确定位问题，提出了基于射频识别( RFID)定位技术的检测列车定位方案：在接触网支柱安装电子射频标签，在检测列车内安装射频阅读器，当检测列车高速通过电子标签时，车内的射频阅读器可瞬时获取到标签里程信息，实现检测列车精确定位。通过性能比选和大量现场试验，选定了作为定位源的电子射频标签，并在北京局管内的京沪高速铁路对该定位方案进行了试验验证，结果表明单点里程定位重复性平均达到0.37 m，定位精度达到2 m，满足高速铁路基础设施检测定位需求。

The paper proposes an inspection train positioning scheme based on RFID positioning technology in the hope of improving the accuracy of the data obtained in the dynamic inspection on HSR infrastructure. By installing electronic radio frequency tag to the catenary mast and radio frequency reader to the train,the reader will be able to pick up the kilometerage information stored in the tag as the train passes through the mast,therefore accurately position the vehicle. The electronic tag,in other words the positioning source,was elected after a comparison of the performances and numerous in-situ tests and it was tested on the Beijing-Shanghai high-speed railway which is in the jurisdiction of Beijing Railway Bureau. The results show that the repeatability of the locating point stand at 0. 37 meter on average and its accuracy reaches 2 meters,which meet the positioning requirement in HSR infrastructure inspection.
