摘 要
随着科技的发展，特别是微电子技术的发展，单片机的应用已经深入到生活的各个领域。本文以STCC89C52为控制芯片，DS1302为时钟芯片，DS18B20为温度传感器，HS0038红外一体接收头作为红外接收器，以此接收并处理遥控器按键信号并用来矫正时钟时间。同时，本设计还加入了定时和设定温度上下限的功能，当达到预设时间时执行开关灯命令，当温度低于温度下限或高于温度上限时执行开空调命令，开关器件为两个大功率电磁继电器。本设计中所有外设数据显示于LCD12864液晶，形成一个良好的用户界面。硬件电路图和PCB用Protel99SE绘制，软件开发环境为KeilV3，设计实物为万用板焊接电路，经调试各项功能均已正常实现。

ABSTRACT
With the development of science and technology, especially the development of microelectronics technology, SCM applications have been deeply into all areas of life. Taking STCC89C52 as control chip, for DS1302 clock chip, DS18B20 as temperature collector, HS0038 infrared receiving head as integrated infrared receiver, signal receiving and processing the remote control buttons, in order to correct the clock time. At the same time, the project also joined the function of timing, and setting temperature of upper and lower, executive orders open to turn off the lights when preset time is reached, when the temperature lower than the temperature is lower or higher than the temperature limit command execution open air conditioning, for electromagnetic relay switch device. The whole project all the data shown in LCD12864 LCD, forming a good user interface. Made in Protel99SE, the hardware circuit diagram and PCB software development environment for KeilV3, project physical for universal plate welding circuit, through debugging functions are normal.
