基于ZigBee的家庭新风系统的设计(含电路图)(开题报告,论文11000字,电路图)
摘 要
随着人们对居住环境要求的提高于各类的空气净化设备。但市场上的净化设备多基于红外无线控制，在控制效率、操作灵活度和调节实时性等方面与人们所要求的可视化、智能监控、无线互联等相去甚远。随着智能家居概念的普及，设计出更加智能化的新风监控系统也成为人们迫切的需求。
本设计介绍了基于ZigBee实现的家庭“新风系统”来满人们净化室内空气的应用要求。该系统包括监测终端、协调器和APP应用三部分，协调器和监测终端搭建ZigBee网络汇集环境采集信息。协调器和APP用蓝牙无线相连，实现采集信息的远端显示和相关操作设置命令的下发。监测终端搭载的DHT11、MQ135和GP2Y1014AUF传感器可实时采集室内的温湿度、甲醛浓度和粉尘浓度，搭载有风扇可根据室内甲醛和粉尘浓度的变化或APP端的命令工作引入清新空气净化室内的空气环境；协调器负责蜂鸣器可输出环境参数异常提醒。APP页面可同步显示环境的监测结果、报警状态、设备连接状态、并可设置参数的区间阀值，遥控风扇执行特定的工作。

Abstract
With the improvement of people's requirements for the living environment in all kinds of air purification equipment. However, the purification equipment on the market is mostly based on infrared wireless control, which is far from the visualization, intelligent monitoring and wireless interconnection required by people in terms of control efficiency, operation flexibility and real-time adjustment. With the popularization of the concept of smart home, the design of a more intelligent fresh air monitoring system has become an urgent need.

This design introduces the application requirements of the family "fresh air system" based on ZigBee to purify the indoor air. The system includes three parts: monitoring terminal, coordinator and APP application. The coordinator and monitoring terminal build ZigBee network to collect environmental information. The coordinator and the APP are wirelessly connected with Bluetooth to realize the remote display of the information collection and the issuance of related operation setting commands. DHT11, MQ135 and GP2Y1014AUF sensors equipped with the monitoring terminal can collect the indoor temperature and humidity, formaldehyde concentration and dust concentration in real time, and the fan can introduce the indoor air environment according to the change of indoor formaldehyde and dust concentration or the command of the APP terminal; the coordinator is responsible for the buzzer to output the abnormal reminder of environmental parameters. The APP page can synchronously display the environment monitoring results, alarm status, equipment connection status, and set the interval threshold of parameters, and the remote control fan to perform specific work.
