Submersible pump system with electric current detection and analysis
The patent US12044239B2 describes a submersible pump system designed to enhance the monitoring and control of submersible pumps. The system includes a submersible pump for water storage, an electric current detection unit to monitor the drive electric current, and a storage unit for retaining this data. An identification unit is also integrated, enabling data transmission and reception with the storage unit. The system can calculate various electric current parameters, such as standard deviation, maximum and minimum values, and the rate of change over time, to assess the operational state of the pump. Additionally, it features a water level detector to monitor the stored water level, further informing the pump's operational status.
The identification unit is capable of executing learning control, utilizing machine learning or deep learning techniques to establish virtual boundaries that differentiate normal and abnormal operational states. The system can predict future operational states based on current conditions and various detected parameters, including water content, temperature, and discharge metrics. It can also communicate abnormal operation types to external devices and control multiple pumps, ensuring that those identified as likely to be in an abnormal state are only operated in emergencies. The patent also encompasses a computer-readable medium and programs that facilitate the operation of the detection and identification units, allowing for the storage and analysis of both electric current and water level data to maintain optimal pump functionality.
