AI Technical Summary

Technical Problem

Multi-stage pumping station systems lack integrated sensor arrays across pumping stations, making it impossible to acquire hydraulic parameters of each pumping station in real time. This results in faults not being detected in a timely manner, and the lack of distributed actuators leads to low efficiency in adaptive regulation.

Method used

A multi-stage pump linkage control system is adopted. The controller receives the operating parameters of the sensor array in real time, uses the abnormal state identification circuit to identify faults and generate parameter adjustment commands, drives the actuators to make coordinated adjustments, and records the operating parameters and command information in combination with the data storage module to realize the automatic identification of fault sources and coordinated parameter adjustment.

Benefits of technology

It significantly improves the adaptive adjustment efficiency of multi-stage pumping station systems, can quickly locate the time point of failure, avoid system instability caused by the spread of failure, reduce deployment and maintenance costs, and improve the timeliness of fault response.

Abstract

The utility model relates to the technical field of water pump control, in particular to a multi-stage pump linkage control system which comprises multiple stages of pump stations connected in series, a water conveying pipeline connected with the adjacent pump stations, a controller, a sensor array, an abnormal state recognition circuit and an executing mechanism, and the sensor array, the abnormal state recognition circuit and the executing mechanism are electrically connected with the controller. The controller is used for receiving operation parameters of each stage of pump station in the sensor array, sending the operation parameters to the abnormal state identification circuit to execute fault identification, generating a parameter adjusting instruction according to an abnormal signal output by the abnormal state identification circuit, and sending the parameter adjusting instruction to the sensor array; the controller is further used for controlling the executing mechanism to execute the parameter adjusting instruction. According to the invention, the fault source can be automatically identified, the parameter cooperative adjustment of the execution mechanism can be triggered, and the self-adaptive adjustment efficiency of the multistage pump station system can be obviously improved.
