摘　　要：现有风扇不管人体是否需要,都按照预先设定的模式运行,这使得使用者非常被动。利用单片机将人体运动传感器与温湿度传感器相结合,系统先设置26℃、26.5℃、27.3℃三种温度区间,不同温度区间与相应的风速对应,同时风扇自动校正网络时间,适时环境温度与档位相匹配,转速将根据时间划分及设置的温度区间来进行转动。再通过监测正常人在舒适环境中睡眠时身体各部位的几种体动情况,归纳出人体在冷热环境下体动时间短、周期短的特征。当使用者使用夜间智能模式后,系统自动监测周围环境温湿度情况,结合人体体动特征判断此时人体体动是否是由于冷热引起的,再根据所设温度区间及对应的时间自动向上一级或向下一级档位匹配,直到达到人体真正对风力的需求。实现真正意义上的根据人体需求的智能控制风扇,具有较高的应用意义。Regardless of whether the human body needs the existing fan,it operates in a preset mode,which makes the user very passive.The single-chip microcomputer is used to combine the human body motion sensor and the temperature and humidity sensor.The system first sets three temperature ranges of 26℃,26.5℃,and 27.3℃.Different temperature ranges correspond to the corresponding wind speeds,and the fan automatically corrects the network time,and the timely ambient temperature matches the gear,and the rotation speed will rotate according to the time division and the set temperature interval.Then,by monitoring several kinds of body movements of various parts of the body when a person sleeps in a comfortable environment,the characteristics of the body′s short body movement time and short cycle in the hot and cold environment are summarized.When the user uses the night intelligent mode,the system automatically monitors the surrounding environment temperature and humidity,combined with the body movement characteristics to determine whether the body movement at this time is caused by cold or heat,and then according to the set temperature range and the corresponding time,it will automatically match up or down one gear until it reaches the real wind demand of the human body.Realizing the intelligent control of the fan according to the needs of the human body in a true sense has high application significance.
