摘要
基于DS18B20的温度控制系统,利用C8051F020及其外围接口电路对直流稳压电源温度进行测量控制。温度传感器DS18B20对直流电源三点测温,信号通过C8051F020进行处理。若温度超过设定值,C8051F020发出控制指令,直流电机工作,电机带动风扇对直流电源降温。当温度达到设定值时,电机停转,数码显示芯片MAX7219实时显示温度。
The temperature control system based on DS18B20 adopts C8051F020 and its external interface circuit to carry out the measurement control for direct current manostat power temperature. The temperature sensor DS18B20 measures the temperature of direct current in three points. The signal is processed by C8051F020. If the temperature is higher than the set value, the C8051F020send the control command. The direct current motor and the fans operate to lower the temperature of direct current. When temperature achieves the set value, the motor stops and the digital display core MAX7219 displays the real-time temperature.
