Embodiment Construction

[0056] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions.

[0057] Taking the drainage system of Hangzhou Economic and Technological Development Zone as an example, the system has five pumping stations, each pumping station has several units, each unit has different power, five reservoirs, several drainage manholes, several drain pipe. In order to maximize the efficiency of each pump station and each unit, save energy and reduce consumption, and prevent sewage overflow in some areas and cause surrounding environmental pollution, the overflow minimum control technology of rain and sewage mixed flow pipes in urban drainage systems is introduced. The steps are as follows:

[0058] 1. Analyze the basic data of a single node, such as the diameter of the manhole, the bottom high-rise, the top high-rise, etc., and input the uncertain hydraulic model of the urban drainage system proposed by the patent appli...

Abstract

The invention relates to a control method which makes sewage overflow of mixed flow pipe net of storm-water and sewage in urban drainage system minimum. At present there is no effective method to solve the control of overflow of mixed flow pipe net of storm-water and sewage. In the invention the control technology of minimum overflow is established based on mixed flow pipe net of storm-water and sewage in urban drainage system, by data structure, system identification, data mining, predictive control technology and Kalman prediction estimation. By the technology, control action for system in current hour is calculated. User can control the running of pump effectively by bottom PLC control technology. It can not only save the energy but also solve the sewage overflow of mixed flow pipe of storm-water and sewage.

Description

technical field [0001] The invention belongs to the field of information technology and relates to automation technology, in particular to a control method for minimizing the sewage overflow of a rain-sewage mixed-flow pipe network in an urban drainage system. Background technique [0002] With the rapid development of cities, urban drainage has become one of the bottlenecks restricting the rapid development of cities. Urban drainage is mainly aimed at the existing drainage facilities in the city. Through the drainage system pipe network model and real-time monitoring data, the overall operation of the drainage system is optimized to avoid environmental pollution caused by sewage overflow, improve the comprehensive operation efficiency of the pumping station network, save energy and reduce consumption, and improve the city's economic efficiency. Flood prevention and flood control capabilities. [0003] However, in the urban drainage project, the sewage treatment plant has a...
