Embodiment 1

[0059] An intelligent drainage dispatching control system for a pumping station includes a data detection unit, a mode selection unit, a dispatching unit and a control unit, and the data detection unit, the mode selection unit and the dispatching unit are respectively connected to the control unit.

[0060]Each pump station includes water inlet pipes, local water collecting pipes, water inlet pools (or pump pools), water pumps, water outlet pools (or elevated wells), and water outlet pipes connected in sequence. The local water collection pipe is used to collect the sewage collected by the local pipe network and transfer it to the water inlet tank. The water pump is arranged in the pump room, and the water pump is driven by an electric motor. Among them, the water inlet pool, the pump pool and the water outlet pool or the high level well of the pumping station are equipped with liquid level sensors, and the liquid level sensors are used to output the liquid level signals of th...

Embodiment 2

[0082] The mode selection unit is also configured with a plurality of middle-level mode interfaces, and the middle-level mode interfaces are used to obtain user selection requests;

[0083] The control unit is further configured to: establish an energy-saving mode, a long-life mode and a high-efficiency mode corresponding to each middle mode interface, and request to enter the corresponding energy-saving mode, long-life mode and high-efficiency mode based on user selection. in,

[0084] In the energy-saving mode, the dispatching unit calculates the energy efficiency coefficient and establishes an energy-saving model based on the obtained power signal and flow signal; the control unit calculates the energy efficiency coefficient based on the energy efficiency coefficient, the energy-saving model, and the selected constant liquid level mode, constant pressure mode or current limiting mode, Control the frequency conversion operation of each water pump in the pumping station accor...

Embodiment 3

[0129] The data detection unit is also used to obtain the flow signal of the local water collecting pipe in a single pumping station;

[0130] Wherein, when the data detection unit cannot directly obtain the flow signal of the local water collecting pipe in a single pumping station, the dispatching unit can calculate the local water collecting pipe flow through the flow rate of the upstream and downstream pumping stations, and the local water collecting pipe Intake flow = the sum of the flow from the pump station to the downstream pump station - the sum of the flow from the upstream pump station to the pump station;

[0131] The mode selection unit is also configured with a high-level mode interface, and the high-level mode interface is used to obtain the user's selection request;

[0132] The control unit is also configured to: establish an automatic mode corresponding to the high-level mode interface, and request to enter the corresponding automatic mode based on the user's ...

Abstract

The invention discloses an intelligent pump station drainage scheduling control system. The technical scheme includes that the intelligent pump station drainage scheduling control system comprises a data detection unit, a mode selection unit, a scheduling unit and a control unit; the data detection unit is used for acquiring liquid level signals of water inlet pool and a water outlet pool of an individual pump station, pressure signals of a water outlet pipe in the individual pump station and flow signals of the water outlet pipe of the individual pump station; multiple low-level mode interfaces are configured in the mode selection unit, and the low-level mode interfaces are used for acquiring selection requests of users; the control unit is configured in the manner of establishing a constant level mode, a constant pressure mode and a current limit mode corresponding to each low-level mode interface and entering the corresponding constant level mode, constant pressure mode and currentlimit mode. The pump stations can be mutually scheduled, disorderly drainage between the upstream and downstream pump stations is avoided, drainage orderness of the overall pump station is effectivelyimproved, and drainage efficiency is improved.

Description

technical field [0001] The invention relates to the field of control scheduling, in particular to an intelligent drainage scheduling control system for pumping stations. Background technique [0002] In the urban sewage treatment system, the drainage pumping station is not only responsible for transporting the entire urban sewage to various sewage treatment plants, but also has the functions of grid filtration, anaerobic treatment of buffer pool and other sewage pretreatment, and water allocation of drainage pipe network, etc. . [0003] Its main task is to collect the sewage discharged by various users, and after lifting the sewage to a certain height, it flows to the next pumping station by gravity, or pushes it to the next pumping station by pressure, and the last pumping station discharges the sewage to the sewage treatment factory. [0004] As a result, in the daily drainage scheduling, disorderly drainage of each pumping station is likely to occur, which affects the ...
