Problems solved by technology

Although these methods can achieve dynamic prediction and control for the complex operation state of the pipeline network to a certain extent, due to the limitations of the PC system load tolerance and fuzzy experience control, it is difficult to predict all unknown operation scenarios in the long-term work process, the stability of the control It is still not guaranteed, and the occurrence rate of control failures is much higher than that of PLC-based control systems. At the same time, it is generally aimed at the local control of a certain pumping station or water intake pump room, and the multi-point network synchronous control of comp

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In order to overcome the technical problems that the sewage pipe network and sewage treatment plant used in the actual operation of the existing sewage system operate independently, lack of information exchange and coordination and scheduling, and the comprehensive efficiency of the sewage pipe network and sewage treatment plant is low, the present invention A scheduling control system for sewage system is provided, wherein two-stage pumping stations are set in the sewage pipe network. It should be noted that the present invention does not limit the number of stages of pumping stations, and the setting of order-level pumping stations here is only for illustration In...

Abstract

The invention provides a dispatching control system and method for a sewage system. The dispatching control system comprises a water inlet pump room and first-stage pumping station linkage control unit, a first-stage pumping station and second-stage pumping station linkage control unit, a factory and network combined dispatching control decision-supporting database and a water inlet pump room discretization flow control unit, wherein the water inlet pump room and first-stage pumping station linkage control unit is used for controlling conveying flow of a first-stage pumping station; the first-stage pumping station and second-stage pumping station linkage control unit is used for controlling conveying flow of a second-stage pumping station; the factory and network combined dispatching control decision-supporting database is used for revising and setting control conditions of all control units; the water inlet pump room discretization flow control unit is used for realizing intelligent linkage control of different water inlet flows and different liquid level regions of a pipe network of a sewage plant. By adopting the dispatching control system provided by the invention, the intelligent automatic linkage control of the sewage pipe network and the sewage plant under a dynamic sewage pipe network liquid level condition is realized; the system is convenient to mount, debug and maintain and relatively abundant remote management functions are provided; the whole control system has a device fault early-warning protection function and long-time stable and intelligent dynamic operation control can be realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically, to a dispatch control system and method for sewage systems. Background technique [0002] The urban drainage system undertakes the important function of urban sewage collection and treatment, and is an important municipal infrastructure to ensure people's lives, urban environment and urban safety. The safe and effective operation of urban drainage pipe network is also an important guarantee for the quality of urban water environment. [0003] In recent years, my country's urban water environment pollution situation is still severe, and problems in the operation of urban drainage pipe networks have become increasingly prominent. Strengthening the informatization construction of urban drainage pipe networks is an important technical means to solve related problems. The sewage pipe network, sewage pumping station and sewage treatment plant are important structural uni...
