摘　　要：针对京广线长葛-临颍段既有ZPW-2000A区间移频自动闭塞技术设备现状,对区间自动闭塞继电电路进行技术改造,增加继电式逻辑检查功能,实现区间轨道电路三点检查,避免列车在区间出现失去分路情况下导致的信号显示升级等不安全因素,确保列车运行安全。In view of the present situation of the ZPW-2000A section automatic block equipment with frequency shift modulated track circuit at the Changge--Linying section of the Beijing- Guangzhou railway, a technical renovation of section automatic block relay circuit was conducted and relay logic check function was added to check the three sections of track circuit in order to a- void signal indicating upgrade or other unsafe factors caused by train losing shunt in the section and to ensure the safety of train operation.

关 键 词：自动闭塞 逻辑检查 继电式
