摘要
城市排水管网监测对于城市水环境治理及雨洪管理具有重要意义,建立排水管网的在线监测体系是智慧排水的重要组成部分,监测点位置的合理选择与布置则是监测有效性的重要保障。为此,基于情景模拟,建立了排水管网监测点的自动识别方法,并以我国华北地区Q市作为案例,建立管网模型,对监测点进行自动识别。该方法可避免人为制定方案时对管网运行规律认识不足的局限性,降低人工制定和调整监测方案的工作量,并且可对监测点进行定量化评估,确保了监测点的代表性。基于系统整体监测的概念进行点位的识别与优化,利用有限数量的监测设备尽可能全面反映排水管网的整体运行状况,是实现智慧排水的基础与必要条件。
Urban drainage network monitoring is meaningful for urban water environment governance and stormwater management.Establishing the on-line monitoring system of drainage pipes is an important part of smart drainage,and suitable selection and arrangement of monitoring points is an important guarantee for the reliability of the monitoring data.Based on scenario simulation,an automatic identification method for monitoring points of drainage network was established.The method was applied to Q city in North China,and a drainage pipe model was established for automatic identification of monitoring points.The method could avoid the limitation of insufficient understanding of the operation of the pipeline network when formulating the program manually,reduce the workload of making and adjusting the monitoring program,and make quantitative evaluation of the monitoring points,so as to ensure the representativeness of the monitoring points.The identification and optimization of monitoring points based on the concept of overall monitoring of the system,and the use of a limited number of monitoring equipment to fully reflect the overall operation status of the drainage network as far as possible,are the basis and requisite for the realization of smart drainage.
