[0024] The left side of the display 12 is electrically connected with a network cable 13, the side, away from the display 12, of the network cable 13 is electrically connected with a PLC controller 14, the front of the PLC controller 14 is electrically connected with a network cable 15, the front of the network cable 15 is electrically connected with an Internet of Things gateway 16 and a touch screen 17, and the touch screen 17 is located on the right side of the Internet of Things gateway 16.

[0025] The main function of the Internet of Things gateway 16 is to control the touch screen 17, the PLC controller 14 and the display 12 in network, so as to facilitate the timely transmission of signals and improve the accuracy of information.

[0026] The end, away from the water tank 1, of the water injection pipe 2 is connected with a water pump, the water injection pipe 2 is located on the right side of the display 12, and the bottom of the water tank 1 is fixedly installed with three supporting legs 18.

[0027] The three supporting legs 18 mainly play a supporting role for the water tank 1, so as to prevent the water tank 1 from shaking due to excessive weight in the water tank 1.

[0028] The pressure sensor 6 is located on the left side of the flow sensor 7 and on the right side of the circulating pump 4.

[0029] The main function of the pressure sensor 6 is to detect the pressure of water in the water outlet pipe 5, so as to prevent the water from being insufficient in pressure and being unable to be monitored in time, and the flow sensor 7 detects the water flow in the water outlet pipe 5, so as to check whether the water in the water tank 1 is sufficient and whether air is mixed in the water.

[0032] Working principle and use process of the utility model:

[0033] Firstly, since the water pump is fixedly installed at the end of the water injection pipe 2 away from the water tank 1, and the liquid level meter 11 is fixedly installed in the water tank 1, the display 12 is fixedly installed above the liquid level meter 11, and the display 12 is electrically connected with the PLC controller 14 through the network cable 13, when the water injection pipe 2 injects water into the water tank 1 through the water pump, the liquid level meter 11 detects the water level in the water tank 1 in real time, when the water level reaches the set position, the display 12 displays the water level, and sends a signal, so that the water pump at the end of the water injection pipe 2 away from the water tank 1 is controlled, and the effect of timely stopping water injection is achieved.

[0034] Meanwhile, since the electromagnetic valve 9 is fixedly installed outside the exhaust pipe 8, and the electromagnetic valve 9 is connected to the network control system, and the pressure sensor 6 and the flow sensor 7 are also connected to the control system, the PLC controller 14 controls the pressure sensor 6 and the flow sensor 7 in real time to observe the water flow and water pressure in the water outlet pipe 5, and sets the circulation pump 4 idle pressure detection lower limit and flow lower limit through the touch screen 17, if the frequency of the circulation pump 4 has reached the upper limit 50HZ, but the pressure sensor 6 and the flow sensor 7 are lower than the circulation pump 4 idle pressure detection lower limit and flow lower limit value respectively, it is determined that there is air in the circulation pump 4, at this time, the circulation pump 4 needs to be paused, and the electromagnetic valve 9 is opened to let the air out from the inside of the exhaust pipe 8, so that the effect of automatic air exhaust is achieved.

[0035] Finally, when the flow and pressure in the circulation pump 4 are normal, water will be discharged outward through the water pipe 10 through the water outlet pipe 5, so that the effect of timely water use at each position is achieved.
