WATCHDOG在汽轮发电机组状态监测系统中的应用

WATCHDOG in Application to the On-Line Monitoring System for Turbo-Generator Set

本文介绍一种适合于汽轮发电机组状态监测系统的“看门狗”功能,它可以在很短时间内发现由于外界干扰而导致的计算机的锁死,并马上自动使计算机恢复正常运行。从而提高在线状态监测系统的可靠性。

This paper introduces a watchdog function which is suitable for the on-line monitoring system for tur-bo-generator set.The watchdog can detect computer program halt brought about by the external distur-bance in a short time,and make the computer work smoothly again at once,so that the reliability of on-linemonitoring system is upgraded.
