基于VME的健康监测系统

A VME Based Health Monitoring System

针对BEPCⅡ中VME机箱运行状况监测的需要,研究并实现了一种VME健康系统。该系统由一台PC和一个插有CMM(Classic Monitor System)监控板的VME机箱组成。CMM监控板收集VME机箱供电,温度和风扇速度等状态信息,并通过串口将这些信息送到该PC上。采用字符驱动接口协议StreamDevice开发了串口的EPICS异步驱动,通过字符串的方式收集这些信息,并以EPICS记录的方式存放在PC IOC数据库中。利用BOY设计人机界面显示VME机箱供电,温度和风扇速度等状态信息,当记录值偏离正常范围时,颜色会变红。这给VME机箱的日常维护带来了极大的方便。

It introduces a VME based health system for monitoring the working status of VME crates in the BEPCII.It consists of a PC and a VME crate where a CMM（Classic Monitor System） is installed.The CMM module is responsile for collecting data from the power suppy and temperature as well as fan speed inside the VME crate and send these data to the PC via the serial port.The author developed EPICS asynchronous driver by using a character-based device protocol StreamDevice.The data is saved into EPICS IOC database in character.Man-machine interface which is designed by BOY displays the running status of the VME crate including the power supply and temperature as well as fan speed.If the value of records display unusual,the color of the value will be changed into red.This can facilitate the maintenance of the VME crates.
