基于GPS浮动车法的城市PM2．5监测系统设计

为了解决现有P M2．5监测站成本高、监测数据更新时间长、在具体位置处监测值不够精确等问题，设计了一种基于 GPS浮动车法的城市PM2．5监测系统.该系统包括车载PM2．5检测设备和监控中心两部分，车载检测设备的主控芯片为LPC2366.通过将车载PM2．5检测设备装载到城市移动车辆上，收集整个城市的PM2．5数据，生成城市PM2．5的分布图与点聚图，并通过网页的形式进行发布.该系统大大降低了P M2．5监测成本，增强了监测实时性，提高了监测的效率.

Urban PM2.5 Monitoring System Based on GPS FIoating Car Method

In order to solve the problem of high cost,long update time of the monitoring data,and inaccurate value in some specific loca-tion of the PM2.5 monitoring station,the urban PM2.5 monitoring system based on GPS floating car method is designed.The system in-cludes the vehicle detection equipment for PM2 .5 and the monitoring center.The main control chip of the vehicle detection equipment is LPC2366.The urban PM2.5 data is collected by the PM2.5 testing equipment installed in the moving vehicles,then the data is converted into the PM2.5 distributed map and clustered map,and the maps are released on the web.The system greatly reduces the cost of PM 2.5 monitoring,enhances the real-time of monitoring,and improves the efficiency.
