基于CAN的全电子计算机联锁系统设计

摘要

联锁软件在计算机联锁系统中起到着核心作用,即专门负责执行联锁运算.计算机联锁系统平台如果在运行工作的过程中出现故障或者系统功能失效,极有可能会引发列车相撞事故.故此,保障计算机联锁系统软件的可靠性是该领域发展建设、研究设计的一项重大课题.本文重点探讨分析CAN总线通信技术在全电子计算机联锁系统设计中的应用,以铁路车站分布式计算机联锁系统为背景,采用二级CAN总线架构模式和排队机制,结合列车信号机电灯电路的功能和控制技术条件来进行.提出相关的设计方法,以期对相关软件的研发起到参考作用.%Interlocking software plays an important role in the computer interlocking system,which is specially responsible for the implementation of interlocking operation.If the failure of the computer interlocking system platform in the process of running or the failure of the system function,it is very likely to cause the train collision.Therefore,to ensure the reliability of computer interlocking system software is an important subject in the field of development and research and design.This paper focuses on the analysis of the application of CAN bus communication technology in the design of full electronic computer interlocking system in the railway station,the distributed computer interlocking system as the background,using two CAN bus architecture model and queuing mechanism,combined with the train signal lamp circuit function and electromechanical control technology terms.The related design method is proposed,in order to provide reference for the development of related software.
