摘要
对主副灯监测电路系统进行了论述,将几种实现方法进行比选,得出利用比较器的方法实现监测较为容易可行.通过对信号机点灯系统的监测电路改进,为判断信号机断丝故障提供了方便;信号机点灯系统只调整部分参数仍能保证显示正常,故障自动监测.由于在电路系统设计中取消监测外线,也降低了由于断线等造成的故障率.系统具有报警准确、显示直观等特性,符合故障―安全原则.
The main and anxiliary lighting systems with automatic fault monitoring were enunciated along with a comparison of several implementations. We found the method of using comparators was easier and feasible. The improvement of its monitoring circuit could help determine the fault signal and find the broken wire. The cancellation of the outside circuit in design could also reduce the failure rate caused by broken wites. The system is accurate in alarming,and good at intuitive display and other functios. It is quite consistent with failure-security principles.
