机车微机控制系统架构设计

摘要

In order to improve performance and efficiency of locomotive control,a network control system based on microcomputer was proposed.The microcomputer control device is the core of the system,and put display screen, monitor host and remote monitor device are integrated to form a network structure with redundancy function.The computer control device uses Freescale′s MK60N5 12VMD100 as main processor and uses Echelon′s Neuron chip as slave processor.The remote monitor device uses satellite and GPS to communicate with the ground control cen-ter.Compared with traditional means of communication,the system has simple structure and high reliability of com-munication.%为了提升机车控制性能和效率，提出一种应用于机车的微机网络控制系统。该系统以微机控制装置为核心，利用LonWorks网络将微机显示屏、机车监控主机、远程监控等装置组成具有冗余功能的网络结构。其中微机控制装置以飞思卡尔公司的 MK60N512VMD100为主处理器、Echelon 公司的Neuron芯片为从处理器，它们之间通过令牌传递协议进行并行通信；机车远程监控装置采用卫星和GPRS双通信模式与地面监控中心进行通信。通过对微机网络控制系统的研究与设计，完成了该系统的软硬件构架，相比传统通信方式，可以简化结构，提高机车通信的可靠性。
