Multi-stage pump station dynamic constant liquid level intelligent adjusting method and system
The invention discloses a multi-stage pump station dynamic constant liquid level intelligent adjusting method and system. The method comprises the steps: obtaining working relation data of a multi-stage pump station; obtaining a first relation between the water flow and the liquid level of a first pump station according to the working relation data; obtaining a first pump station historical record; optimizing the first relation according to the first pump station historical record to obtain a second relation; inputting the first water flow demand and the second relationship into a liquid level prediction model to obtain a predicted liquid level change amount; judging whether the predicted liquid level change amount exceeds a first pump station liquid level change threshold value or not; and when the predicted liquid level change amount exceeds the first pump station liquid level change threshold value, obtaining a control parameter according to the predicted liquid level change amount and the working relation data, and executing a first control instruction according to the control parameter, wherein the first control instruction is used for controlling all the pump stations in the multiple stages of pump stations. According to the invention, the technical problem that in the working process of a multi-stage pump station in the prior art, the liquid level of each stage of pump station cannot be kept in a stable constant liquid level state in dynamic change, and the use effect of the multi-stage pump station is affected is solved.
