单轨交通环线轨道电路常见故障判断与处理

重庆市单轨交通二号线信号系统采用环线轨道电路,利用轨道环线向列车发送ATP信号并同步接收TD信号反映车辆的位置信息 在站台区利用开门环线向列车发送开门信号,控制列车开门时机。环线轨道电路的故障将严重影响系统的安全性和运行效率。本文结合工程项目实际,重点介绍道岔区段、车站内轨道区段和开门环线重叠区段常见故障的判断与处理。

Common Malfunction Diagnosis and Treatment of Monorail Loop Track Circuit

The signaling system of the monorail of Chongqing line 2 adopts the loop track circuit which sends the ATP signal to the monorail train and receives the TD signal which can reflect the position of train. In the station area the loop track circuit can send the signal which can be used to open the train door. The failure of loop track circuit will seriously affect the system＇s security and operation efficiency. By examining the actual project, the article focuses on the troubleshooting of the common malfunction in switching section and overlapped section of the track section in station and loop track circuit of opening door.
