| 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Windows 2000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。 |

| Abstract: |
| 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. |
| Key words: Windows 2000 WinDriver |
