摘要
针对小范围区域的空气污染紧急溯源问题,基于物联网与WebGIS技术,通过车载移动物联网监测的方式,设计了面向小尺度空气污染物的移动监测与实时可视化系统,可实现局部范围内空气污染物多参数并行监测、传输、处理、存储、分析与可视化。该系统能够对采样时间和空间间隔内的数据进行过滤,参考国标六项污染物等级阈值设定预警值,为小尺度空气污染物位置溯源提供监测预警服务。结合外出移动监测案例完成对福建省福州市闽侯县空气污染热点区域排查,获取不同监测参数在时空分布上的变化趋势,验证移动监测与实时可视化在城市小尺度范围内快速精准溯源的有效性。
Aiming at the emergency tracing of air pollution in a small area, based on the Internet of Things and WebGIS technology, a mobile monitoring and real-time visualization system for small-scale air pollutants is designed by means of vehicle-mounted mobile Internet of Things monitoring, which can realize multi-parameter parallel monitoring, transmission, processing, storage, analysis and visualization of air pollutants in a local area. The data in the sampling time and space interval of the system are filtered, and the warning values are set by referring to the six national standard pollutant level thresholds, so as to provide monitoring and warning services for the location traceability of small-scale air pollutants. Combined with the case of out-of-town mobile monitoring, the hot spots of air pollution in Minhou County, Fuzhou City were investigated,and the changing trends of different monitoring parameters in time and space distribution were obtained, which verified the effectiveness of mobile monitoring and real-time visualization in tracing the source quickly and accurately in small-scale cities.
