摘要
本次设计是基于单片机的智能温控风扇。以STC89C52单片机为核心,可以实现对风扇的有效控制。可以根据需要设置不同的温度,如果温度在设定值最大值和最小值之间时则启动风扇弱风档,如果温度超过设定的数值时将会变到大风档,如果温度低于最小值时风扇停止转动,启动什么风挡由外部温度决定。测得的温度值保存在温度传感器DS18B20内部ROM中,断电后保存的数值不变。基于单片机的智能温控风扇可以满足人们的不同需要,具有一定的实用意义。
This design is based on the MCU intelligent temperature control fan. The paper applies STC89C52 microcontroller as the core, which can achieve the effective control of the fan according to the needs of different temperature. If the temperature value stays within this range between the set maximum and minimum value, the fan could start weak wind profile;if the temperature exceeds the set value , the fan will change to the strong wind profile;and if the temperature is lower than the minimum value, the fan could correspondingly stop rotating. That is to say, starting the windshield is decided wholly by external temperature. The measured temperature values are stored in the DS18B20 internal temperature sensor ROM, with constant power saving value. Intelligent temperature control fan based on MCU can meet the different needs of people, and has good practical significance.
