分布式空气质量远程集中监测管理系统设计

为了能够远距离实时监测空气中PM2.5和PM10的浓度变化情况,采用C/S架构设计了分布式空气质量远程集中监测管理系统,系统由多个空气质量监测站和监测中心两部分组成。空气质量监测站作为客户端利用嵌入式处理器LPC2129作为控制核心,通过传感器SDS011采集空气中悬浮颗粒物PM2.5和PM10的浓度,并通过GPRS模块SIM900A建立与监测中心服务器的TCP/IP网络连接,进行数据交互。监控中心服务器接收、处理、统计分析和显示来自各监测站的数据,并存在数据库SQL2008中,便于形成时、日、月和年报表。同时,为环保监察部门和手机APP提供了数据接口,实现资源和数据共享。测试结果表明,该系统实现对分布在远程各地空气中颗粒物浓度的集中监测,且工作稳定可靠,能够为排污企业周围环境评估提供数据依据,也能够为引导市民健康出行提供参考。

Design of Distributed Air Quality Remote Centralized Monitoring and Management System

To monitor the concentrationof PM2.5 and PM10 in the remote air in real time, the distributed air quality remote centralized monitoring and management system is designed using C/S architecture, which is composed of air quality monitoring stations and monitoring center. As a client, the air quality monitoring station uses the embedded processor LPC2129 to be the control core, collecting the concentration of PM2.5 and PM10 in the air through sensor SDS011, and establishes the TCP/IP network connection with the monitoring center server using the GPRS module SIM900A to communicate. The server in the monitoring center is responsible for receiving, processing, statistical analysis and display of data from each monitoring station, and storing them to the database SQL2008 for the hour, day, month and year reports. Meanwhile, the data can be shared by the environmental protection supervision departments and the mobile phone APP. The test results show that the system realizes the centralized monitoring of particles concentration in the air distributed in the distance, and works stable and reliable, which can provide the data basis of the environmental assessment for the sewage enterprises and guide the public to travel healthly.
