Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 , Figure 2 and Figure 5 This embodiment of a multifunctional mobile submersible pump control system includes a control cabinet, a PLC module, a frequency converter, a water pump, an ultrasonic flow meter, and a remote control module. The output terminal of the control cabinet is electrically connected to the input terminal of the PLC module, the output terminal of the PLC module is electrically connected to the input terminal of the frequency converter, the output terminal of the frequency converter is electrically connected to the input terminal of the water pump, the frequency converter and the ultrasonic flow meter are connected bidirectionally via network communication, the output terminal of the ultrasonic flow meter is electrically connected to the input terminal of the remote control module, and the output terminal of the remote control module is electrically connected to the input terminal of the PLC module. A motor is installed inside the water pump.

[0025] In addition, the control cabinet includes potentiometers and a control panel. The control panel helps staff operate the control cabinet more easily. The potentiometer includes line 1, line 2, and line 3. The potentiometer releases control signals by outputting different potentials to line 1, line 2, and line 3 respectively, and further cooperates with the frequency converter to control the forward and reverse rotation of the motor on the water pump. The potentiometer is electrically connected to the frequency converter through line 1, line 2, and line 3.

[0026] In addition, the PLC module includes input terminals, output terminals, power terminals, and neutral terminals. The power terminals can be connected to the power supply to provide stable power to the PLC. The neutral terminals are used in conjunction with the neutral wire to provide a current return path. The output terminals are electrically connected to the input terminals of the frequency converter. The output terminals provide the frequency converter with signals for the motor to rotate forward, reverse, and maintain constant speed, which in turn control the motor on the water pump through the frequency converter.

[0027] In this embodiment, by using a control cabinet, PLC, and frequency converter in combination, the start-up, shutdown, forward and reverse rotation of the motor on the water pump can be controlled locally, thereby controlling the water pump more accurately and facilitating production and disaster relief.

[0028] Please see Figure 1 , Figure 3 , Figure 4 and Figure 5 To improve the convenience of the control system, the frequency converter in this embodiment includes a power input unit, a primary control unit, a secondary control unit, an output unit, indicator lights, and a 485 communication interface. The primary and secondary control units are used to provide the frequency converter with signals such as forward rotation, reverse rotation, and constant speed of the motor, so as to better cooperate with the frequency converter to control the motor on the water pump. The primary control unit includes FWD terminal, SEV terminal, S1 terminal, and COM terminal, and the secondary control unit includes 10V+ terminal, 10V- terminal, and GND terminal.

[0029] It should be further explained that the output terminals include three contacts: Q0.0, Q0.1, Q0.2, and Q0.3. Q0.0, Q0.1, Q0.2, and Q0.3 are electrically connected to the FWD terminal, SEV terminal, and S1 terminal respectively via wires. The output terminal of Q0.3 is electrically connected to the COM terminal. During remote control, a signal is provided to the PLC through the remote control device, and then the PLC module works with the frequency converter to stably control the operation of the water pump. The output terminal of the potentiometer is electrically connected to the 10V+ terminal via line 3, the output terminal of the potentiometer is electrically connected to the 10V- terminal via line 1, and the output terminal of the potentiometer is electrically connected to the GND terminal via line 2.

[0030] In addition, the ultrasonic flow meter includes the flow meter body and a radar detector. The radar detector can detect the water flow in the water pump, thereby assisting the operator in controlling the water pump more accurately. The frequency converter and the ultrasonic flow meter are connected bidirectionally via a 485 communication interface. The remote control module includes an antenna and a controller body. The antenna can be connected to the operator's mobile device, thereby helping the operator to remotely control the operation of the water pump.

[0031] In this embodiment, the remote control module, PLC module, frequency converter and ultrasonic flow meter work together to help users remotely observe the operation status of the water pump and remotely control the operation of the water pump, thus improving the convenience of the system.

[0032] Understandably, by combining the control cabinet, PLC module, frequency converter, water pump, ultrasonic flow meter and remote control module, it is possible to remotely control the start and stop of the water pump, monitor the water pump flow in real time, and provide alarms when the equipment fails. It is simple and convenient to use.

[0033] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0034] The working principle of the above embodiments is as follows:

[0035] When local control is selected, users can change the voltage or current value using the potentiometer on the control cabinet, and then transmit the electrical signal to the PLC module. The PLC module and the frequency converter work together to adjust the pump speed and flow rate. When remote control is selected, users can connect to the remote control module via an antenna. At this time, the wireless communication module is working, and users can remotely start and stop the equipment through remote control methods such as a mobile APP client, and send signals to the frequency converter through the PLC, thereby achieving precise and multi-functional control.
