[0058] In this embodiment, the inlet and outlet of frequency conversion pump No. 5 and frequency conversion pump No. 6 are respectively provided with pressure detectors. The pressure detection sensors on the inlet ends of frequency conversion pump No. 5 and frequency conversion pump No. 6 are used to read the analog value of the pressure value through the PLC control box, thereby performing pressure protection on frequency conversion pump No. 5 and frequency conversion pump No. 6.

[0059] The pressure detection sensors on the outlet ends of the No. 5 and No. 6 variable frequency pumps are used to read the water outlet and terminal pressure of the pumps through the PLC control box, thereby providing pressure protection for the No. 5 and No. 6 variable frequency pumps.

[0060] Furthermore, in this embodiment, the water level in the water tank can be sensed by the gravity sensor on the liquid level float or by setting a liquid level sensor, so that the sensor can control the start and stop of the water pump through the feedback control system of the signal, and the water pump can be interlocked by setting the water tank signal priority. When the upper water level is low, the upper and lower water pumps are interlocked and closed, and the effect of manual opening is shielded at the same time. (Among them, the method of setting the water tank signal priority and the working principles of the gravity sensor and the liquid level sensor are all prior arts, not the technical points of the present invention, so they are not repeated here.)

[0061] The present invention monitors the state of the water level in the water tank in real time, automatically adjusts the operating state of the pump, realizes multiple protections, and ensures the safety of our domestic water. By setting two water tanks in each water supply control system, it can be guaranteed that they serve as backup for each other during cleaning to ensure the normal water supply of the system. When the water level of the local water tank drops to an ultra-low liquid level or the upper-level water tank rises to an overflow level, the water pump of the present invention is locked and cannot be opened manually, thereby protecting the water pump. The adopted water tank overflow control method has a beneficial effect on ensuring the safety, stability and efficiency of industry and life. The present invention can effectively solve the problems of water pump operation and water tank overflow, and improve the reliability and production efficiency of the equipment.
