摘　　要：继电式逻辑检查是基于信号电路判定行车过程逻辑、接连自动闭塞系统自动防护、人工解锁盘报警的信号电路安全补强。通过严格检查校核施工过程中的电源使用路径,避免混电情况下试验不出来的现象,同时务必要增加特殊场景试验,可以明显检查特定情况下逻辑检查系统盲区,更好校核混电电路。Relay logic check is based on the signal circuit to determine the driving process logic,the automatic protection of the continuous automatic block system,and the manual unlock disk alarm.By strictly checking the power supply use path in the verifi cation construction process to avoid the phenomenon of test not coming out under the mixed condition.At the same time,it is necessary to increase the special scene test,which can obviously check the blind area of the logical check system under specifi c circumstances,so as to better check the mixing circuit.
