铁路车站分布式计算机联锁系统
Distributed Computer Interlocking System of Railway Station
摘要
Abstract
Distributed computer interlocking system moves switch machines* signal, track circuits, cab signaling and other trackside execution unit of outdoor equipment to the next to the controlled device, the system achieves distributed control through secure communication system. The system consists of the monitoring machines, repair machines, interlock host, trackside execution units, secure communications systems, power supply and power supply network. Trackside execution unit consists of the power supply module, trackside communications extension, switch machine module, signal module, track module, cab signaling module and other components. The secure communications system consists of a communication host, trackside communication extension and communication networks. The interlock host communicates with the communication host by using redundant RS-422 bus. Point-to-point redundant fiber-optic communication is used between communication host and trackside communication extension. Dual CAN bus communication is used between the trackside communication extension and the control module. The system provides power to trackside execution unit by the way of the power supply panel through the redundant power supply network of independent uplink and downlink throat section. What's more, the system has the advantages of saving cable, reducing project cost, and also reducing break or mixed line fault and security risks. It has been put into operation at Xigu power plant station in Lanzhou, and the operation has been safe and reliable up to now.关键词
