摘要
对于采用ZPW-2000A预叠加电码化设备的车站,列车进行上、下行线转线运行时,需要司机利用开关进行机车信号载频人工切换,通过对既有站电码化电路进行设计,实现载频自动切换。解决单线双向自动闭塞区间接发车人工载频切换存在的操作频繁复杂、切换地点和时间不明确的问题。
For the stations with ZPW-2000A equipment for overlap coding in advance, when the train is running from the uplink line to the downlink line, it needs the driver to press the switch for changing the carrier frequency of cab signal manually. In this paper, by designing the code circuit of the existing station, the automatic switching of carrier frequency has been realized. It solves the problems of frequent and complex operation and unclear switching location and the vague time of manual switching carrier frequency for the single section with double-direction automatic blocking.
