中文摘要：
有轨电车位置检测是现代有轨电车信号系统的关键和难点.目前有轨电车位置检测方法多样,但都存在或适用性不强、或可靠性安全性低的不足.应用高压脉冲轨道电路和射频识别技术组合的方式,既可以解决传统轨道电路、计轴器和检测环线等适用性不高的问题,又能够解决单一高压脉冲轨道电路和射频识别技术难以同时满足“故障-安全”原则和定位精确性的问题.
英文摘要：
Tram position detection is the key and difficulty of the modern tram signal system. At present,the position detection method of trams is varied. However, they have the problems of insufficient applicability,low reliability or security. The combination of the high-voltage pulse track circuit and RFID （Radio Frequency Identification） technology can solve not only the problem of insufficient applicability of the traditional track circuit, axle counter and test loop, but also the problem that the high-voltage pulse track circuit or RFID technology can＇t satisfy the principle of ＂ fault-safety ＂ and realize positioning accuracy simultaneously.
