自动闭塞区间继电式逻辑检查功能电路优化

Optimization of Relay-type Logic Check Function Circuit of Automatic Block

进站信号机内方第一区段红光带开放引导信号时,区间继电式逻辑检查电路将无法正常工作,通过对自动闭塞区间继电式逻辑检查功能站内结合电路进行优化,可在特定情况下保证电路正常动作,减少多余的操作。

When the calling-on signal within the red light strip of the first section in advance of the home signal is cleared, the relay type logic check circuit with block signalling cannot work normally. Through optimizing the relay type logic check combination circuit with automatic blocks within the station, the circuit can operate normally to reduce operations in specific cases.
