城市地下管网水质可视化预警系统研发及应用

针对城市地下管网空间复杂性及其部分管道水质监控信息化程度的不足,基于三维GIS软件SuperMap强大的图形数据处理能力,开发了城市地下管网水质可视化预警系统。将三维可视化场景、管道模型和监测成果与SuperMap软件系统有机地融合,建立直观、有效的城市地下管网三维可视化场景,能够动态展示和实时交互式地查询可视化模型信息;同时通过对水质监控指标的阈值进行设置,系统能够自动识别异常监控指标值,并将异常信息推送给监控人员,从而达到监控预警的目的。该系统为城市地下管网水质监控提供了一个直观交互式的信息可视化管理平台及监控预警平台,具有一定的实际意义和应用价值。

Development and Application for Visualization Early Warning System of Urban Underground Pipelines about Water Quality

In view of the complexities of urban underground pipelines and the insufficient level of information about the part of pipelines for water quality monitoring,the visualization early warning system of urban underground pipelines about water quality has been developed with the SuperMap which has the powerful three-dimensional graphics capabilities.In this system,the three-dimensional visualization of the scene,the pipes model,the monitoring results and the SuperMap system were combined together,and the three-dimensional scene of urban underground pipelines was built visually and effectively.The information of visualization model can be displayed dynamically and queried interactively in real time.Meanwhile,the system automatically identifies abnormal index value of monitoring instruments by setting up the thresholds of water quality monitoring indicators,and pushes abnormality information to monitoring persons,so as to achieve the purpose of monitoring and early warning.Therefore the system provides an intuitionistic and interactive visualization management and security control platform for urban underground pipelines,which has some practical meaning and application values.
