Control device for submerged pump

The invention relates to a control device for a submerged pump. The control device comprises a signal input end, a power module, a central data processing module, a fault self-diagnosis module, a fault signal processing module, a fault storage module, a control signal output module and a signal output end. The signal input end is connected with the central data processing module, and the central data processing module is connected with the fault self-diagnosis module and the fault signal processing module; and the fault self-diagnosis module is connected with the fault signal processing module, the fault signal processing module is connected with the fault storage module, and the central data processing module and the fault signal processing module are both connected with the control signal output module. During work, a sensor detects the working state of the submerged pump or a submerged stirrer and sends a signal, the signal is output to the central data processing module to be processed, and whether the si
