无线温控风扇毕业设计.docVIP

摘 要 在人们的日常生活中，电风扇非常受到人们的喜爱。相对于空调，电风扇不仅价格便宜，使用方便安全，而且耗电量小。然而，人们在熟睡时，外界随着温度变化而降低，这时候人们会容易感冒，尤其是中老年人和小孩更加容易生病。但随着社会的发展，使用智能控制风扇渐渐起来。本文就采用ZigBee无线温控风扇的转速，主要是用两块ZigBee核心板，分别当做发送模块和接收模块，发送模块接上DS18b20温度传感器和电源，接收模块主要外接电机，温度传感器采集外界温度，对发送模块上的程序解析编译后通过天线传输给接收模块，最后对其的程序进行解析编译，通过电机驱动控制风扇，在此，可以设定上下限，让风扇的转速随外界温度变化而改变。这样的话，不仅更加的节能，而且有利于人们的健康。 关键词: Zigbee 智能风扇 DS18b20 Abstract In Peoples Daily lives, the electric fan is very popular with people. Relative to the air conditioning, electric fan is not only cheap, easy to use security, and power consumption is small. People, however, when sleeping, the outside world as the temperature changes, and the people will be easy to catch a cold, Especially middle-aged and old people and children are more likely to get sick.But with the development of the society, the use of intelligent control fan up gradually. In this paper, using ZigBee wireless temperature control fan speed, Mainly is to use two pieces of ZigBee core board, respectively, as sending and receiving module, Sending module DS18b20 temperature sensor and the power is connected, receiving module is mainly external motor, temperature sensor to collect the outside temperature, the transmission module programs on parsing the compiled by antenna transmit to the receiving module, and finally the compiled program parsing, driven by motor control fan, the lower limit can be set up, let the speed of the fan varies with temperature change and change. In this way, more energy saving not only, and is conducive to peoples health.
