基于CAN总线的机车微机控制系统研究

The research of locomotive microcomputer control system based on CAN bus

文章根据现有机车操纵控制系统的功能和控制方式,确定CAN总线作为其设备级控制总线．依据计算机网络操作系统的设计思想．对控制系统网络进行了总体设计,提出了一种网络冗余的方案,并进行了应用层程序的设计,实现了网络即插即用,冗余、自检、数据收发等功能．

By referring to control methods and functions of the existing locomotive,this paper selects CAN bus as the control bus of the equipments. Based on the design principle of computer network operating system,it designs the whole network of the control system and presents a scheme of network redundancy.And it designs the application layer program,it realizes the functions of plug＆play,redund ancy,self-test and transceiver of datum etc.
