摘要：车站信号微机监测系统是在目前的各种铁路信号设备中必不可少的铁路设备之一，它可以监测铁路中各种信号设备的实时运行状况，并且在有故障发生时，对值班人员进行报警，是铁路中故障-安全原则实施中很重要的一部分内容。本次设计是对铁路部分设备的具体运行情况进行监测，通过对进、出站信号机和转辙机的监测来判断是否正常运行，监测的依据是根据数据采集模块采集到的动作电流来和正常的动作电流进行对比，从而监测设备是否正常运行。上位机的实施程序由组态软件完成。对于进、出站信号机来说只需要监测他们的继电器组合吸起落下情况就可以，对于转辙机来说，除了有继电器的情况需要我们监控以外，还有动作电流需要监测，他们的动作电流前者为直流，后者为交流，需要用不同的数据采集模块。82102

Design of Computer Monitoring System for Station Signal

Abstract: Computer monitoring system for station signal is one of the station equipment in the railway。 It can monitor all kinds of situations which is working of signal equipment。 It can caution the operator in charge when there are some troubles。 It is the most important part in the railway if you want the fail- safe principle is working。 The design is to monitor the part of the station equipment in real time, it can judge whether the equipment is working accurately through monitoring the home signal、exit signal and point switch。 We compare the action current from data acquisition module with the accurate current to know if the equipment is working accurately。 The work of computer depend on configuration software。 We just need to monitor the situation of the relay which has two condition of holding and dropping for home signal and exit signal。 But the point switch has two types of zd6 and zd9, the former has direct-current and the latter has alternating current。 So they need different data acquisition modules
