- Title:
- Construction and Data Application of Online Liquid Level Monitoring System in Kunming Drainage Network
- Keywords:
- drainage network; liquid level monitoring; liquid level data analysis; warning and forecasting
- 摘要:
- 在对昆明排水管网运行管理需求分析的基础上，筛选长期固定及临测点，构建在线液位监测网络体系。从预警预报、旱天液位规律、雨天液位响应以及上下游联动4个方面进行液位数据分析及应用模式探讨，从而指导排水设施运行维护、划分区域溢流风险等级、识别水位变化规律、进行异常排水事件溯源、评估雨天溢流风险及分析上下游连通管道液位相关性。利用液位监测数据指导排水设施运行管护，提升城市排涝应急响应能力，为其他城市构建液位监测网络、排水设施智能化运行管理提供了经验。
- Abstract:
- Based on analysis of the operation and management requirements of Kunming drainage network, long-term fixed and temporary measuring points were selected to construct an online liquid level monitoring system. Liquid level data analysis and application mode were discussed from four aspects (warning and forecasting of water level, variations in liquid level in dry weather, response of liquid level in wet weather and relationship of upstream and downstream level),so as to guide the operation and maintenance of facilities, divide the risk level of different area, identify the law of water level change, trace the source of abnormal drainage events,assess the overflow risk in wet weather and analyze the correlation of liquid levels in upstream and downstream connected pipelines. The liquid level monitoring data can be employed to guide the operation and management of drainage facilities, improve emergency response capability of urban drainage, which provides experience for other cities to build liquid level monitoring network and realize intelligent management of drainage facilities.
