[0020] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0021] See Figure 1 , is a schematic diagram of the structure of the utility model. The utility model is a water pressure alarm device for a fog pile spray system, comprising a water tank 1, a spray system host 2, a dry pipe 11, a fog pile 12, a nozzle 13, an electric control valve 14, an electric control box 7, a pressure transmitter 6, an audible and visual alarm 8, a digital display 9, an Internet of Things SIM card, a redundant PLC 10 and a mobile terminal;

[0022] The spray system host 2 includes a drive motor 4, a high-pressure plunger pump 5 and a control box 3. The water pipe of the water tank 1 is connected to the high-pressure plunger pump 5. The drive motor 4 is connected to the high-pressure plunger pump 5 through a pin shaft. The drive motor 4 is connected to the control box 3 through a cable. The control box 3 is provided with a control button.

[0023] The output pipeline of the high-pressure plunger pump 5 is connected to the main pipe 11, a fog pile 12 is arranged at the end of the main pipe 11, a nozzle 13 is arranged at the end of the fog pile 12, the number of the fog pile 12 and the nozzle 13 matches, and five are arranged on each, the pressure transmitter 6 and the electric control valve 14 are arranged on the main pipe 11 in front of the fog pile 12, the redundant PLC 10 is arranged in the electric control box 7, the sound and light alarm 8 and the digital display 9 are arranged on the door of the electric control box 7, the Internet of Things SIM card is inserted into the card slot of the redundant PLC 10, and the redundant PLC 10 communicates wirelessly with the mobile terminal through the Internet of Things SIM card;

[0024] The redundant PLC 10 includes a redundant power supply, a redundant CPU, a digital output module, an analog input module and an analog output module. The output end of the digital output module is connected to the sound and light alarm 8, the input end of the analog input module is connected to the pressure transmitter 6, and the output end of the analog output module is connected to the electric control valve 14 and the digital display 9. The electric control valve adopts an electric butterfly valve.

[0025] Working principle: The operator turns on the spray system host 2 button on the control box 3 to put the spray system host 2 into operation. After starting the drive motor 4, the water delivered by the water tank 1 is pressurized to 8-10 kg high pressure by driving the plunger pump, and then delivered to the mist pile 12 and sprinkled on the area with a radius of 0-30 meters through the nozzle 13. The mist pile 12 spray system enters the working state.

[0026] When the spray system host 2 uses the plunger pump to continuously deliver water pressure within the required range of the system, the pressure transmitter 6 transmits the detected real-time water pressure in the form of a voltage-type analog signal to the PLC in the electric control box 7 through the control cable, and then transmits it to the digital display 9 connected to its module through the redundant PLC 10, and displays the real-time water pressure value in the main line of the fog pile 12 spray system. At this time, the water pressure is within the range required by the system, and the sound and light alarm 8 is in a stopped state; when the delivered water pressure is lower than the lower limit value required by the system, the digital display 9 displays the real-time water pressure, and the digital signal output by the PLC triggers the sound and light alarm 8 to perform an alarm operation; after the water pressure returns to the required range of the system, the digital signal that triggers the sound and light alarm 8 stops outputting, and the sound and light alarm 8 stops the alarm operation and is in a stopped state; when it is necessary to adjust the nozzle spray volume and pressure, the PLC analog output module outputs an analog signal to adjust the opening degree of the solenoid valve, thereby adjusting the nozzle water pressure and flow of the fog pile spray system.

The methods used in the above embodiments are conventional methods unless otherwise specified.
