Take monolithic integrated circuit AT89S51 as the core multi-channel fixed time controllers, may carry on the time cut-out control to the multi-channel domestic electric appliances, realizes a controller to be possible to control the multi-channel current collector, meanwhile has the clock calibration, the time demonstrated, reports to the police and so on the functions, will realize the network control digital family for later to provide some foundations. This article and establishes fixed time the time through the pressed key adjustment current time, again through DS1307 demonstrated the current time, after the hypothesis fixed time , LED demonstrates the countdown, when fixed time the time at the appointed time, separates the relay and sends out reports to the police. This timer characteristic has: Operates simply, the function is practical; The application scope is broad, may simultaneously control many electric appliances; The electronic formula time is fixed time precise, the time is fixed time long.
