城市轨道交通信号系统联锁控制权交接研究

Research on Interlocking Control Rights Handover of Urban Rail Signal System

城市轨道交通信号系统中,调度人员通过列车自动监控系统中心工作站和车站工作站都可以向联锁机发送控制命令,但是同一时刻联锁机只能有一个指令源。因此在设计联锁系统软件结构时,需要采用合理的联锁控制权交接机制,防止控制权交接错误。从联锁控制权交接问题入手,总结联锁控制权交接原则,详细分析各个设备之间采用不同互联方式时的联锁控制权交接方案,并对不同方案的影响和优缺点进行比较,为联锁系统的软件设计提供理论依据。

In the urban rail signal system, dispatchers can send commands to the interlocking machine through the center workstation or the station workstation of the automatic train supervision system. But, the interlocking machine can receive commands from only either of the two at the same time. Therefore, in the design process of the interlocking software structure,it is required to adopt a reasonable handover mechanism to prevent fault handover. This paper focuses on the interlock rights handover, sums up the principles guiding the interlocking control rights handover, and analyzes in detail the schemes for interlocking rights handover with different connecting methods between each subsystem. Then, the advantages and disadvantages of each scheme are compared to provide theoretical basis for the design of interlocking system software.
