The system uses AT89C52 and DS1302 as the core module, implementing an ultra-long timing controller. The ultra-long timing controller can be widely applied in many circumstances, and work for several years or even several decades, and also can be used as the law switch. Working with solid-state relays, it turns to be a high voltage timer switch. The system selects DS1302 as the system clock source, and chooses AT89C52 as the system control center. In addition, the system inehdes the LCD display mod-ule, the keypad control module and the automatic reset circuit module.
