摘要
大秦线站内为ZPW-2000A轨道电路,文章分析了为实现机车信号载频自动切换而需要计算机联锁驱动的方向继电器、检测继电器、载频切换继电器、股道转频继电器的设置目的、设置范围及技术条件。
This paper analyzes the purpose, scope and technical conditions for setting directional relays, detection relays, carrier frequency switching-over relays and track rotation frequency relays driven by computer-based interlocking to realize the automatic handover of carrier frequency of cab signal with ZPW- 2000A track circuit installed in station.
