本电地暖控制器采用单片机技术来实现对温度的测定、控制和输出。控制器的构成包括：继电器模块，蜂鸣器模块，数码管模块，单片机模块，复位电路，独立键盘模块，温度传感器模块。控制器的工作流程为：单片机通过继电器控制发热电缆的电压和温度；两个温度传感器分别测定发热电缆的温度和室内空气温度，按键电路决定将传感器和设定温度中的一路信号发送至数码管显示；单片机将传感器温度和报警温度进行比较，若传感器端温度过高，则启动蜂鸣器模块进行报警。-This electrical floor-warming controller aims at measuring, controlling and ouputing temperature. The said controller including: relay module, buzzer module, nixie tube module, single-chip module，reset circuit, independent key module and temperature sensor module. The working procedure of the controller will be showed as: the single-chip microcomputer controls voltage and temperature of heating cable via relay module　two sensor measure temperature of heating cable and the room seperately, the key module determing sending whether the signal of one of the sensors or determined temperature to the nixie tube module　the single-chip microcomputer compares the temperature of sensor and alarming temperature, if the temperature of the sensor is higher, the buzzer module will be set up to alarm.
