A dynamic monitoring system of urban atmospheric environment based on ZigBee and GIS technologies

针对城市大气环境污染问题,采用ZigBee和GIS技术研发了城市大气环境实时动态监测系统。该系统分为系统感知层和系统应用层。系统感知层是基于ZigBee无线自组网技术的硬件无线传感网,负责城市大气环境监测指标的实时动态定位采集与传输;系统应用层是基于WebGIS的城市大气环境实时动态监测软件系统,实时监测并模拟城市大气环境的动态变化,精确定位污染源地理分布并预警污染事故的发生。感知层与应用层通过GPRS方式实现数据的双向传输,系统的数据管理采用Oracle11g实现。试运行结果表明,该系统实现了对大气环境监测数据的自适应采集以及实时、可靠地高效传输,为城市大气环境质量的监控与治理提供良好的技术支撑与可靠的数据支持。

A real-time dynamic monitoring system of urban atmospheric environment is developed based on the technologies of ZigBee and GIS. The system consists of perception and application layers. The perception layer is a hardware wireless sensor net,which collects and transmits real-time monitoring data of atmospheric environment within the net; The application layer is a Web GIS-based realtime monitoring software system for atmospheric environment,which monitors and simulates the real-time change of urban atmospheric environment,positions accurately pollution source locations and warns pollution accidents happening. GPRS is responsible for the data transmission between the perception layer and the application layer,and oracle11 g is responsible for the database management of the system. In the operation,the system realizes adaptive data collection and effective transmission,and provides a technological support and basic data for monitoring and governance of urban atmospheric environment.
