摘要近年来，我国部分地区的气候有着很明显的变化，雾霭天气变多，风沙情况更加严重等等。在这个空气质量越来越差，环境污染越来越严重的背景下，人们也意识到了保护环境减少污染的重要性，于是各种大气监测系统应运而生。72712
本论文提出了一种基于ZigBee的大气质量监测系统。该系统主要芯片分别为CC2531芯片和CC2591芯片。CC2531作为整个系统的核心，CC2591在系统起到信号的放大和防止信号衰弱导致通讯中断的作用。本系统采用灰尘传感器、温湿度传感器、二氧化硫传感器和一氧化碳传感器，采集空气中的各种数据进行分析，系统中的无线通讯模块将收集到的数据样本传输到数据终端上，再由人工进行分析。本文完成了相关硬件电路设计和软件流程图的设计。
系统具有成本低、操作简单、实用性强等特点，最重要的是该系统的布置不会影响到当地的生态环境与结构。该系统无需人员长期看管，能够自动存储采集数据，达到自动控制的效果。

Design of ZigBee-based Air Quality Monitoring System
Abstract In recent years, the climate of some areas has a very significant change, mist weather increases, the situation is more serious, and so on sand。 In the air quality is getting worse, more and more serious environmental pollution in the background, people have realized the importance of protecting the environment pollution is reduced, so a variety of atmospheric monitoring system came into being。
This paper presents a system for detecting air quality based on ZigBee。 The system uses two chips respectively chip CC2531 and CC2591 chip。 CC2531 as the core of the whole system, CC2591 system plays in the amplified signal and prevent signal weakness causing interruptions of communication role。 The system uses sensor dust, temperature and humidity sensors and sulfur dioxide sensor, the air collecting a variety of data for analysis。 Data system wireless communication module the collected sample data is transmitted to the terminal, and then manually analyzed。
System has low cost, simple operation and practical features, the most important is the arrangement of the system will not affect the structure of the local environment and ecology。 The system does not need long-term care personnel, can automatically store the captured data, to effect automatic control。
