排水管网在线监测布点数量的确定
- Title:
- Quantification of On?line Monitoring Layout in Urban Drainage Network
- 摘要:
- 排水管网在线监测对城市排水智慧化管理、系统优化调度、在线预警报警等工作的开展起到重要的支撑作用，需要在一定的经济成本约束下，制定合理有效的排水管网在线监测方案。其中，在线监测布点数量的确定是制定方案的基础工作，但目前主要依赖于人为主观判断，缺少定量化的方法。提出了排水管网分级监测的思路，根据整体、分区和源头三个层级的监测思路，量化不同层级下最优监测布点的数量及不同监测点数量设置下可实现的最优监测效能，可指导排水管网在线监测布点数量的确定。将该方法分别在城市雨水系统和污水系统监测点数量确定中进行应用，能够支持监测方案的量化评价、监测方式和指标的筛选等。
- Abstract:
- As for the intelligent management, system optimization scheduling and on?line warning?alarm of urban drainage, the on?line monitoring plays an important supporting role. Therefore, reasonable and effective on?line monitoring scheme for urban drainage should be developed under the constraint of economic cost. Among them, the quantification of the monitoring points is the basic work for the whole scheme. However, at present, it mainly relies on subjective judgment and lacks quantitative method. This paper puts forward the idea of hierarchical monitoring of drainage network. Through quantifying the number of optimal monitoring points at three levels, namely, the overall level, the regional level and the source level, and optimal monitoring efficiency which can be achieved under different monitoring points, the idea can guide the quantification of on?line monitoring layout in urban drainage network. The method is applied in the urban stormwater system and sewage system respectively, and it can support the quantitative evaluation of monitoring program, monitoring mode and index selection.
