本设计主要是解决普通家电的智能化控制，主要描述一个遥控定时插座的设计与制作。该定时插座可以弥补现实生活中普通插座功能的不足，能够通过外设按键或遥控器设置插座的供电时间，使外接电器可以按照一定规律工作，既可以达到智能控制的目的，又在很大程度上起到节能的作用。
本系统由STC8C52单片机电路+时钟DS1302电路+LCD1602液晶显示电路+按键电路+继电器控制电路+蜂鸣器报警电路+红外传感器电路+电源电路组成。
1、DS1302时钟芯片，准确计时，自带3V纽扣电池，当系统掉电后，纽扣电池供电给时钟芯片继续工作，再次上电无需重新设置时间。
2、LCD1602液晶可以显示时、分、秒、星期、年、月、日。
3、可以设置5个开关开的时间和5个开关关的时间，每一个时间都可以单独设置成是否工作有效（Y/N），设定的时间并具有掉电保存功能，保存在STC单片机的内部，上电无需重新设置。
4、继电器吸合指示灯亮实现开关开，继电器断开指示灯灭实现开关关，继电器可以外接其他的家用电器。
5、具有自动模式和手动模式，手动模式下按加、减键就可以实现开关的开和关。
6、开机默认是自动模式，当现在的时间和设置开的时间一致时，继电器工作打开开关，当现在的时候和设置关的时间一致时继电器断开关闭开关。
7、开关的开和关蜂鸣器的提示声不同，当开关开时，蜂鸣器会发出滴滴的提示声，开关关时，蜂鸣器会长鸣一声。
8、具有红外遥控功能，可以用红外遥控器完成整个产品的操作。“|<<”标识手动或切换，“>>|”表示设置或换页，“—”表示手动情况关闭或设置值--，“+”表示手动情况打开或设置值++。
