基于在线监测数据的排水管道运行规律识别

Recognition of drainage pipeline operation law based on online monitoring data

随着在线监测技术的发展,排水管道水位和水量在线监测得到越来越多的应用。以西南某城市主干管的在线监测数据为例,建立了流程化和标准化的分析方法。通过液位与流量的旱天规律曲线图和场次降雨散点图,充分挖掘数据信息并进行集中表达。结果表明,应用此分析方法,可识别管道在旱天和雨天的水位负荷、冒溢风险、水量规律、转输能力等特征,为事故预警、风险防控、水量核算、管网调度提供支撑。

With the development of on-line monitoring technology the level and flow monitoring of drainage pipes has been increasingly used.A process-oriented and standardized analysis method was established with online monitoring data of main pipeline in a city in southwestern China.Dry day law curve and event rainfall scatter diagram of level and flow were designed to fully mine and express data information.The application of this method can identify the characteristics of the pipeline's level load,overflow risk,water volume law,and transfer capacity,etc.in dry and rainy days,and provide support for accident early warning,risk prevention and control,water volume accounting,and pipe network scheduling.
