分布式计算机联锁系统应用分析

Application Analysis of Distributed Computer Interlocking System

分布式计算机联锁的控制方法是将计算机联锁系统的执行部分硬件设备放置于轨旁,联锁运算部分放置于机械室或调度中心机房,双方通过冗余光纤网、工业以太网、CAN总线进行通信.这种控制方法具有降低室外通信信号设备造价、节省信号楼空间、减少电缆混线、断线故障等优点.本文针对分布式计算机联锁系统的应用进行分析.

The control method of distributed computer interlocking is to place the execution part of the hardware of computer interlocking system beside the track while to place the operation part of the system in an equipment room or a computer room in the control center.The two parts of the interlocking system communicate with each other via redundant optical fiber network,industrial Ethernet and CAN bus.Such a control method has the advantages of reducing the cost of outdoor communication and signal equipment,saving the space of signal building,and minimizing the risk of cable mixing and breaking.The Application of distributed interlocking system is analyzed.
