摘　　要：介绍一种温控开关,采用STC89C52单片机作为控制器,对室内温度进行控制。温控开关包括温度采样模块、单片机芯片控制模块、按键显示模块及电源模块的硬件电路和软件实现方法,具有温度设定功能、室温校准功能、温度调节功能、睡眠功能及回差功能。引入了多点温度采集方法校准,解决了现有同类产品温度采集不准确的问题。并将产品应用于家用电暖器的控制,试验结果稳定,可以实现温度的精确控制,装置的精度和稳定度都达到要求。This paper introduced an intelligent temperature control switch,which is designed to take STC89C52 microcontroller as the core controller to control room temperature. The device consists of temperature sampling module,single chip control module,key button display module and power module,hardware and software module implementations. It has a temperature setting function,room temperature calibration function,temperature regulation,sleep function and hysteresis function. The multi-point temperature calibration acquisition method is introduced to solve the problem that the existing similar product＇s temperature measurement is not accurate. And the products are used in household electric heater control. The test results show that the precise temperature control can be achieved and precision and stability of the device will meet the requirements.
