武汉轨道交通1号线径河延伸线联锁电路分析

Analysis of the Interlocking Circuit for Jinghe Extension Project on Wuhan Rail Transit Line 1

承担安全执行功能的车站列车控制器和继电器之间的连接,是保证系统功能控制和实施的重要一环,车站列车控制器和外部电路的电气特性匹配、电路控制时序、命令触发条件等,都是整个信号控制系统的关键研究因素。以武汉轨道交通1号线径河延伸线为例,从驱动电路、采集电路、关键监督控制电路、关键监督前置继电器电路等方面,介绍了新一代车站列车控制器的特殊联锁电路逻辑,为施工设计和运维保障提供分析依据,同时也为后续类似车站列车控制器的研究提供参考。

The connection between zone controller and relay with vital execution functions is a key link,it ensures the functional control and execution of the system. The electrical characteristics match between zone controller and external circuit,the sequential circuit control and command trigger condition are all key factors in the signal control system. Taking Jinghe extension project on Wuhan Line 1 as the example,the special interlocking logic of train controller at new generation station is introduced,including the driving and acquisition circuits,key supervisory control circuit and relay circuit. This research provides an analytic basis for engineering design and operation maintenance,also a reference for the subsequent similar zone controller research as well.
