Description
Technical field
The present invention relates to technical field of sewage, more particularly, to the Dispatching Control System for sewerage and
Method.
Background technology
The important function for the municipal sewage collection system processing that sewerage system carries, is to ensure people's lives, city ring
Border and the important civilian infrastructure of urban safety, the safe and effective operation of urban drainage pipe network is also urban water environmental quality
Important leverage.
In recent years China's Urban Water Environment pollution situation is still severe, and the operating problem of urban drainage pipe network is also increasingly convex
Aobvious, the informatization for strengthening urban drainage pipe network is the important technical for solving relevant issues.Sewage network, sewage pumping station
It is the important feature unit of urban sewage system with sewage treatment plant, realizes sewage network, sewage pumping station and sewage treatment plant's connection
The intelligent operation control of dynamic operation can effectively improve sewerage optimization operation level, ensure sewage network operation safety,
Reduction emits excessive, and then controls overflow, reduces the stably reaching standard that sewage treatment plant is improved to sewage treatment plant's influence of fluctuations and optimization
Operation level etc., realizes that sewage network and the technical need of sewage treatment plant coordinated operation intelligent control are increasingly urgent.
Drainage pipeline networks is open system, and running environment complicated condition is changeable, and the flow and liquid level of pipe network are in different zones
Between the dynamic change of non-regularity is generally presented, sewage pumping station needs reply different at any time with the running of sewage treatment plant
Running status, especially under condition of raining, pipe network water can quickly occur complexity dynamic change, pipe network complicated and changeable
Running status, the operation control to sewage pumping station and sewage treatment plant brings great challenge.Meanwhile, sewage network running
For complicated nonlinear change system, the disturbance of control signal can be amplified by running the fluctuation in control process, and pipe network is transported
Capable safety operation level requirement is again higher, it is necessary to strict guarantee sewage network, the safety levels level of sewage pumping station, how
It is very big that sewerage complicated and changeable realizes that sewage network, sewage pumping station and the operation control of the intelligent linkage of sewage treatment plant have
Technological challenge.
Existing sewerage is mostly sewage network and sewage treatment plant separately respective independent operating, phase in actual motion
Lack information mutual communication and coordinated scheduling between mutually, this substantially reduces sewage network and the comprehensive effectiveness of sewage treatment plant.Sewage network
Pumping plant is also mostly controlled using artificial experience, and sewage treatment plant inflow pump house also uses the constant flux controls with artificial experience more,
Also indivedual sewage pumping stations realize PLC controls and the constant flow VFC of sewage treatment plant inflow pump house of permanent liquid level,
But also only it is to be controlled on the spot for local pumping plant or pump house running situation, it is independent mutually between different pumping plants or pump house, no
It can realize and interconnect, and constant level and flow control also are difficult to reply pipe network running status complicated and changeable in real time.
Also some have researched and developed the control methods such as fuzzy control, the control of empirical law time series forecasting, but these method controls
Amount of calculation is larger in implementation process processed, is both needed to realize control based on PC system supplymentaries.Although these methods to a certain extent may be used
To realize dynamic prediction and the control for the complicated running status of pipe network, but because PC system loadings are resistance to during long-term work
It is difficult to the limitations such as all unknown operation scenes of prediction by ability, fuzzy experience control, the stability of control can't ensure, control
Rate of breakdown is far above the control system based on PLC, while being generally still directed to some pumping plant or inlet pumping station just
Ground is controlled, and has not been achievable the multidrop network Synchronization Control of the pipe network system of complexity.And the existing control based on PLC is also only capable of reality
Existing fairly simple constant level, constant flow rate and empirical law control etc., are based only on stable PLC control system and realize
Many pumping plant Synchronization Controls, sewage network and the sewage treatment plant's linkage Intelligent Dynamic control of complex grid state are also rarely reported,
Existing pumping plant intelligent operation control technology can't meet the intelligent information running technology hair of existing sewerage well
Exhibition demand.
