Drainage system scheduling method and device

Abstract

The embodiment of the invention provides a drainage system scheduling method and device. The method comprises the steps that according to the precipitation of each area in a drainage system in a preset current time period and the water inlet flow of each area in the preset current time period, the trained neural network model is utilized to predict the water outlet flow of each area in a preset future time period; taking the safe water outlet flow range of each pump station in the drainage system and the maximum sewage treatment capacity of each sewage treatment plant in the drainage system asconstraint conditions; and taking the minimum sum of energy consumption of all pump stations in the drainage system as a target, and obtaining a scheduling scheme of each pump station in each regionaccording to the water outlet flow of each region in the preset future time period. According to the embodiment of the invention, the method employs the machine learning, enables the neural network tobe used in the scheduling of the drainage system, shortens the decision-making time in a control process, and provides data support for the optimal scheduling operation of the drainage system.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a drainage system scheduling method and device. Background technique [0002] The common drainage system joint scheduling method is often independent of each link. Although this operation method can make each link achieve the highest operating efficiency, the overall operating efficiency of the drainage system is often low, and some drainage systems cannot be fully utilized. its water storage capacity. In addition, under this mode of operation, the drainage system will also have many problems such as overflow and the impact of the influent flow of the sewage treatment plant, causing urban water environment pollution. The overall scheduling method can improve the operation efficiency of the drainage system and alleviate the above problems. [0003] The drainage system is a complex hydraulic system.

[0002] The common drainage system joint scheduling method is often independent of each link. Although this operation method can make each link achieve the highest operating efficiency, the overall operating efficiency of the drainage system is often low, and some drainage systems cannot be fully utilized. its water storage capacity

In addition, under this mode of operation, the drainage system will also have many problems such as overflow and the impact of the influent flow of the sewage treatment plant, which will cause urban water environment pollution. The overall scheduling method can improve the operation efficiency of the drainage system and alleviate the above problems

[0003] The drainage system is a complex hydraulic system. The overall scheduling process needs to be analyzed with the help of the model to take corresponding control measures to optimize the operation of the drainage system. Using the traditional hydraulic model to analyze and predict it, although accurate results can be obtained, it often takes a lot of money The calculation time cannot be applied to the scheduling control of the drainage system
