摘要
电力自动化系统运行于电磁干扰严重的环境,且需要长期连续运行,必须为系统配备看门狗以满足系统的可靠性要求。介绍在Windows2000操作系统下用WinDriver和C++Builder,在工控机看门狗电路的基础上实现2级看门狗的方法。第1级看门狗在应用程序运行异常时重启应用程序;第2级看门狗在第1级看门狗拒动或操作系统崩溃时重启操作系统。该方法实现简单、效果良好。
Power automation system runs continuously in the environment full of electromagnetic interferences. It is necessary to employ watchdog in it. The implementation of 2-stage watchdogs based on Windows 2000,C ＋＋ Builder and WinDrive is introduced. The 1st stage watchdog restarts the application program when it becomes abnormal; the 2nd stage watchdog restarts the whole system when the 1st stage watchdog fails or the whole system halts. It is easy to implement and gets good performance.
