红外遥控定时开关的设计与实现

Design and realization of infrared remote control timer switch

设计一款以STC89C52单片机、DS1302、1602液晶显示、38 k Hz红外遥控器发射接收器为核心,具备调节时间,设置开启时间与工作时间段的遥控定时开关。程序采用C语言编写,具有更好的移植性和可读性,便于修改和增减功能。该遥控定时开关可以通过红外按键设置一天内2组任意开关定时时间段和一个小时内6组快速模式定时,使外接电器能够按照一定规律来工作。该系统的时间正确可靠,可扩展性强,既能达到远程智能控制的目的,又在很大程度上降低能源的消耗。同时借助EDA仿真可以有效地提高开发效率,结合具体硬件电路及程序设计,将理论知识用计算机仿真表现出来,加深学生对知识的理解和掌握,提高了教学效率。

The realization process of a remote control timer switch that has the functions of time regulation,time setting （starting time and working duration）and is based on the IC microcontroller STC89C52,DS1302 and LCD 1602 and 38 kHz IR remote controller’s transceiver is introduced. It is compiled with C language,so it is convenient to modify and add functions. This timer switch is controlled via wireless infrared remote keys,and can set up sixgroup fast mode timing within one hour and twogroup any period switch timing within a day via infrared keys. Therefore,it can make external electric equipments work regularly. It can achieve the purposes of remote intelligent control and reduce energy consumption to a large extent.At the same time it can improve the efficiency of development effectively with the help of EDA simulation. And it shows the theoretical knowledge with computer simulation combined with the specific hardware circuit and the program. This way can deepen students＆#39; understanding of knowledge and master, and improve the teaching efficiency.
