Abstract

The perception of energy conservation and intelligent goes deep into families, with the life increasing and improving quickly,And we design timer socket for energy conservation. The design is the timer socket,And the main function of timer socket is that we time by key or IR Remote.The design consists of STC89C52,DS1302,LCD1602,220VAC to 5VDC power supply,buzzer,key，relay. The design’s driver microchip is STC89C52, The design uses the DS1302 to supply more accurate time,And the design uses LCD1602 to display the year,the month,the day,the hour,the minute,the second,and the operation interface.The design also uses the relay to control the on and off,And the timer socket can time by the remote control. In this paper, the design of the system was introduced through three aspects including the hardware modules, software flow pattern and circuit design and debugging. At the end of this paper, the problems happened during the process of designing the system was summarized.
