摘　　要：在信号微机监测使用过程中,发现道岔动作电流曲线存在某一时段电流值全部为零的现象,对该现象进行了深入分析,发现微机监测统计道岔动作时间的计时电路存在缺陷。通过分析计时电路工作原理,找出了道岔动作电流值全部为零的原因,并提出了改进方案。During the process of signal micro-computer monitoring,I found that all current value of action current curve are zero at a time.The article analyzes this phenomenon deeply.And find that timing circuit for calculates turnout action is defective.Find out why all current value of action current curve are zero at a time by analyzing the timing circuit works.And put forward the improvement plan.
