【 摘 要 】

The data-logging module is a checking module using for saving energy of the street and public lamp. It must install in poor environments and difficult to access for maintenance. So, it should be designed to fault tolerant. The watchdog timer is one technique of the fault tolerant system. However, the power drop is the poor environment, which sometimes, the internal watchdog cannot solve it. This paper presents the hardware watchdog for solving this problem. It will be done hard reset on the controller board. It can solve the problem of electricity has gone down and improved the high fault tolerant to this system.
