用于工控监测系统的多进程软件看门狗

Multi process software watchdog in Industry control and watch

在工控机内置硬件看门狗的基础上,运用Windows系统的消息机制进行多进程通信,设计并实现用于多进程系统的软件看门狗,当某个进程出现异常时,只重新启动该进程或协商重新启动工控机;当整个系统出现异常时,由工控机内置硬件看门狗重启工控机。该多进程软件看门狗成功运用在高压设备在线监测系统中,充分保证了系统不出现"死机"、"跑飞"等异常的情况。

Use windows message to communicate,based hard watchdog,designed and implemented soft watchdog on multi process.When abnormity happen on one process,the process will be restarted,or restart computer by arranger.When abnormity happen on whole system,computer will be restarted by hard watchdog.This soft watchdog is used successfully on high voltage on-line measurement system,protect whole system don t occur exceptional stop.
