摘要
ZPW-2000A轨道电路的方向切换电路为继电接口的形式,当方向切换继电器故障时无法快速定位故障设备;另一方面,方向切换继电器数量较多,需设置独立的组合架,施工维护效率低。提出对通信编码方式ZPW-2000A轨道电路的方向切换电路进行电子化设计,并提出轨道电路电子设备的具体方案,可彻底解决外置方向继电器引发的故障,具有较好的应用前景。
The direction switching circuit of ZPW-2000A track circuit adopts relay interface.When a certain direction switching relay fails,the faulty equipment cannot be quickly located.On the other hand,there many direction switching relays which require independent combination rack,so the construction and maintenance effi ciency is low.Therefore,this paper proposes the electronic design of the direction switching circuit of ZPW-2000A track circuit,and puts forward a specifi c plan for the track circuit electronic equipment,which can completely solve the fault caused by the external direction relays and has a good application prospect.
