摘要
为了实现对空气质量监测管理的网络化和信息化,提出了一个基于ZigBee的大气PM2.5监测系统;该系统对监测点的PM2.5进行周期监测或实时监测,测量值通过zigbee/3G/Ethernet网关发送到远程控制中心,控制中心对各监测点传回PM2.5测量值进行智能处理后得到各监测点所在地PM2.5值;实现的系统浓度测量范围为0.2~1000mg/m^3,测量误差不大于10%,稳定性相对误差绝对值不大于2.5%;本系统除了具有低功耗、低成本、易组网等传感网固有特点外,还具有集中控制、智能处理、自动化程度高和的优点,在工程应用中有很大的优势;系统通过对采集数据进行处理,使系统的准确性提高;并且通过采集的数据可以将失效的节点检测出来,利于系统的维护和更新。
In order to achieve the air quality monitoring and management of network and information technology,proposed PM2.5air monitoring system based on ZigBee.The system of PM2.5monitoring sites periodically to monitor or real-time monitoring,measurement values are sent to the remote control center via Zigbee/3G/Ethernet gateway under control center for all monitoring points back PM2.5measurements intelligent processing each PM2.5monitoring point location value.It has been implemented that the system concentration measurement range is 0.2~1000mg/m^3,the measurement error is less than 10%,the absolute value of the stability＇s relative error is not more than 2.5%.The system in addition to low power,low cost,easy networking and other inherent characteristics of the sensor network,but also with centralized control,intelligent processing,high degree of automation and the advantages of wide application prospects.The most important data will be collected for processing,improve the accuracy of the system.
