摘　　要：站内应答式脉冲轨道电路是一种为非集中联锁车站到发线能动态反映列车占用情况而研制的。它具有省电、省电缆、设备集中从而大量节省投资的特点,适用我国铁路广大无交流电源地区构成车站行车安全控制设备,以保证行车安全。站内应答式脉冲机道电路的远端只设一个电感线圈,利用钢轨实现脉冲的二次传输,在电路中,采用时分制发送和接收脉冲信号,较好地解决了邻线干扰问题。Transmitting-responding pulse track circuit (TRPTC) in non-interlocking station has been researched to dynamically indicate the train occupancy of a track. The advantages of the TRPTC system are saving electrical energy, saving cable and concentrating devices, so it could cut down investment. It could be widely used in railway area without electricity supply, it can ensure the safety of traffic transportation in non-interlocking station. There is only an inductance coil at remote-end of the TRPTC, so pulse signals are transmitted twice by the rail. The pulse signals are transmitted and received in a time-sharing mode, thus resolved the problem of interference to near-lines.
