轨道交通安全计算机平台通用维护模块设计

Design of General Maintenance Module for Rail Transit Secure Computer Platform

现有轨道交通安全计算机平台板卡监控模块存在通用性低、监控信息不全面和处理器资源消耗大等问题。对此,文章提出了一种轨道交通安全计算机平台通用维护模块设计思路。该通用维护模块是以GD32系列微控制器为核心搭建的小体积子板,其有专用的电路对安全计算机平台各个板卡主CPU的运行电压、复位信号和同步信号等进行监测,能够极大地降低安全计算机平台各个板卡监控电路的设计难度,且该通用维护模块的核心器件均能进行国产化替代。

Board monitoring module of the existing rail transit safety computer platform has some problems,such as low versatility,incomplete monitoring information and large processor resource consumption.Therefore,this paper presents a design idea of general maintenance module for rail transit safety computer platform.The general maintenance module is a small volume sub board built with GD32 series microcontroller as the core.It has a special circuit to monitor working voltage,reset signal and synchronization signal of main CPU of each board of security computer platform,which can greatly reduce the design difficulty of the monitoring circuit of each board of security computer platform.Core components of the general maintenance module can be replaced by localization.
