基于单片机的简易定时开关插座的设计与制作

Design and making of simple microcontroller based on the timer switch socket

使用AT89S52单片机设计并制作一个简易型定时开关插座。电路由电源电路、单片机最小系统、数码显示和按键操作电路、继电器强电控制电路四个模块组成,并使用软件和硬件进行测试。本产品能实现24小时内的时间定时,并自动断电,对一些不能长时间通电的电路能够起到保护作用,也可以作为定时控制器使用。

The use of AT89S52 microcontroller to design and produce a simple timer switch socket. The circuit is composed of a power supply circuit, minimum system microcontroller, digital display and button operation circuit, relay power control circuit is composed of four modules, and test with software and hardware. To achieve timing within 24 hours of the time of the products, the time to automatically cut off the power supply circuit power socket, some can not long time can play a protective role, but also can be used as a timing controller.
