基于单片机的风扇温控仪设计摘要电风扇在我们日常生活和工作中是必不可少的工具,尤其是夏天更能给人带来凉爽。但是随着当今能源匮乏,环保节能意识加强,传统电风扇已不足以满足现在的需求。基于单片机的智能控制,本文设计了一款新型智能风扇温控系统,可以自动控制风速。通过感知和检测周边现场的环境温度,风扇会适当的调节自身的转速和频率,根据环境温度也会做出启动,停止等动作,不需要人为操控,具备很强的便捷性。温度传感器DS18B20 内部的 E2ROM 中存储设定的高温和低温数值,掉电后仍然能保存上次设定值,性能稳定,控制准确。该智能电风扇的控制系统运用的是以 STC89C52 单片机作为系统控制的核心;房间温度采用温度传感器 DS18B20 收集。此项设计弥补了传统风扇的种种不足,一方面在日常生活中运用智能温控技术,另一方面可以达到自动调控节省了自然资源。关键词:单片机,交流电机,温度传感器 DS18B20Design of fan temperature control instrument based on single chip microcomputerabstractElectric fans are indispensable tools in our daily life and work, especially in summer. However, with the lack of energy and the awareness of environmental protection and energy saving, traditional electric fans are not enough to meet the current demand.We design an intelligent temperature control fan system with automatic temperature control and wind speed control based on SCM intelligent control. When the ambient temperature rises, the fan will change its speed according to the temperature. When the temperature is reduced, it can also reduce the frequency, without human manipulation, it has a strong convenience. It can detect the ambient temperature accurately and automatically control the starting, stopping and wind speed of the electric fan according to the change of the ambient temperature. The high temperature and low temperature values are stored in the E2ROM of the temperature sensor DS18B20. After the power failure, the last setting value can be saved, the per...
