数显式节能定时控制器的设计

Design of a Digital-display Energy-saving Timing Controller

针对部分家用电器使用时需要限时,设计了一种可以任意设置用电时间的数显式定时控制器,可以消除因遗忘而未及时关断电源所造成的隐患。控制器比普通插座略大,可以直接插入到普通插座,不必改动原来电路。因此使用非常方便,有较大的应用前景。

In view of time limit for some household electrical appliances,this paper gave the design of a digital-display timing controller with its power use time being set at random. The controller can remove hidden danger caused by forgetting to cut off power in time. The controller of a size slightly bigger than a normal socket can be plugged into a common socket,with no modification needed for the electrical circuit. With a convenient usage,it has a good application prospect.
