Embodiment

[0108] The above-mentioned method of the present invention is respectively applied to the sewage pipeline network of two cities of Benk and Xiuzhou below. The sewage pipe network of the city Benk (denoted as FSS-BKN) consists of 1 sewage plant entrance, 64 inspection wells and 64 sewage pipes. Three liquid level gauges and a flowmeter (such as Figure 4 shown), the sewage discharge is about 4100 tons / day; the corresponding water supply network (denoted as WDS-BKN) is composed of 1 water plant, 65 water demand nodes and 93 water supply pipelines. 3 pressure gauges and 1 flowmeter and 40 smart water meters, the water supply is about 4800 tons / day; such as Figure 4 As shown in , the dotted arrow indicates the corresponding relationship between the water supply network nodes and the sewage network inspection wells determined according to the shortest distance. The sewage pipe network of the city Xiuzhou (denoted as FSS-XZN) consists of 1 sewage plant entrance, 1214 inspection we...

Abstract

The invention provides a real-time simulation method of sewage pipe network based on the data of water supply Internet of Things, including an offline module and a real-time online module, the offline module integrates the hydraulic model of the sewage pipe network and the water supply pipe network, and corrects the hydraulic model of each node of the water supply pipe network Historical water consumption, establish a single-objective optimization model for sewage pipe network model correction, determine the transfer coefficient between water consumption at each node and inspection well inflow, real-time online module realizes real-time simulation of hydraulic parameters of sewage pipe network model. The invention fills the gap in the field of real-time simulation of sewage pipe network, is an important supplement to the research field of urban drainage pipe network management, provides important technical support for the management of sewage pipe network system, and has good promotion and practical engineering application value .

Description

technical field [0001] The invention belongs to the field of municipal engineering urban water supply and drainage pipe network, and in particular relates to a real-time simulation technology of sewage pipe network based on data assimilation of water supply Internet of Things. Background technique [0002] The safe operation of urban sewage pipe network directly affects the urban water environment, water safety and people's health. In recent years, with the rapid growth of the urban population, the scale of the sewage pipe network has continued to expand, the topology has become more complex, and the system has become more aging, which has brought great difficulties to the operation and management of the sewage pipe network. The current problems that are prone to occur in the urban sewage pipe network mainly include pipe network deposition, waste water illicit discharge, pipe leakage, misconnection of rain and sewage pipes, and sewage overflow, etc. These problems have serio...
