[0002] In the industrial sector, especially in the control of critical equipment such as factory air compressors, precise and efficient motor control is crucial for ensuring production stability and safety. Traditional air compressor control systems often use a single integrated controller.

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiments of the present application disclose a four-motor control system.

[0033] Reference Figures 1-4A four-motor control system includes four evenly arranged air compressor bodies 1. An electric control box 2 is provided on one side of the four air compressor bodies 1.

The output end passes through the electric control box 2 and is connected to the interior of the electric control box 2. An annular infusion tank 10 is provided inside the heat exchange box 6. The annular infusion tank 10 is arranged on the periphery of the annular heat exchange tank 8. The input end of the annular infusion tank 10 is fixedly connected to an infusion pump 11 through a pipeline. The input end of the infusion pump 11 is fixedly connected to a refrigerator 12. The input end of the refrigerator 12 is connected to the interior of the annular infusion tank 10 through a pipeline. A mounting plate 16 is fixedly connected to the interior of the electric control box 2. A color-changing silica gel 17 is fixedly connected to the top of the mounting plate 16. An electric control component for driving the four air compressor bodies 1 to start at intervals is installed at one end of the electric control box 2. A monitoring component is provided inside the electric control box 2. The electric control assembly includes four motor controllers 13 uniformly fixedly connected to the outside of the electric control box 2, one end of the circuit board 4 is uniformly fixedly connected to four frequency converters 14, the output end of the frequency converter 14 is fixedly connected to a power supply line 15, and the four power supply lines 15 are respectively fixedly connected to the four air compressor bodies 1, and the circuit board 4 is electrically connected to the motor controllers 13, the frequency converter 14, and the air compressor body 1; Furthermore, a plurality of pairs of partition plates 18 are evenly and fixedly connected to the interior of the annular heat exchange chamber 8. The plurality of pairs of partition plates 18 are arranged in a circular shape, and a partition groove 19 communicating with the annular infusion chamber 10 is formed between two adjacent partition plates 18. Furthermore, a heat-conducting ring plate 20 is fixedly connected to the interior of the heat exchange box 6. The heat-conducting ring plate 20 is installed inside the annular heat exchange chamber 8, and the outer side of the heat-conducting ring plate 20 is fixedly connected to the partition plate 18. An electric heater 21 is fixedly connected to the interior of the heat-conducting ring plate 20. In addition, the monitoring component includes a humidity sensor 22 fixedly connected to the inside of the electrical control box 2, a temperature sensor 23 fixedly connected to the inside of the annular heat exchange chamber 8, and a first drain plate 25 fixedly connected to one end of the circuit board 4. The first drain plate 25 is electrically connected to the temperature sensor 23, the humidity sensor 22, the electric heater 21, and the infusion pump 11.

[0034] When in use, four motor controllers 13 are first set up to independently connect and control the four air compressor bodies 1. At the same time, the four motor controllers 13 are connected to the circuit board 4 through the communication interface, so that the circuit board 4 can control the four motor controllers 13 to coordinate control. Then, after the first air compressor body 1 is started and stabilized by the circuit board 4, the next air compressor body 1 is started at a preset time interval. Four frequency converters 14 are set up to adjust the operating speed of the air compressor body 1 according to actual load requirements. When additional power is needed, the super capacitor 3 provides assistance to reduce the impact on the power grid. Then, as the use time increases, the internal working temperature of the electric control box 2 changes. At this time, the humidity sensor 22 and the temperature sensor 23 are respectively set to monitor the humidity inside the electric control box 2 and the temperature inside the heat exchange box 6 in real time. When the internal temperature of the heat exchange box 6 is higher than the preset temperature, the monitoring chip 24 is set to start the infusion pump 11 and the refrigerator 12, so that the infusion pump 11 draws the liquid medium inside the annular infusion tank 10 into the refrigerator 12 for cooling, and then introduces the cooled liquid medium into the annular infusion tank 10, thereby realizing the refrigeration cycle of the liquid medium. At the same time, the circulation pump 7 is started to draw the air inside the electric control box 2 into the inside of the annular heat exchange chamber 8, and then the air is introduced into the inside of the electric control box 2 in conjunction with the air guide pipe 9. At the same time, when the air passes through the inside of the annular heat exchange chamber 8, heat exchange and cooling are achieved through the liquid medium inside the annular heat exchange chamber 8 and the annular infusion chamber 10, thereby reducing the temperature of the air and further reducing the working temperature inside the electric control box 2. In addition, by providing a plurality of partition plates 18 and the use of partition grooves 19, the contact area between the liquid medium and the inner side of the annular infusion chamber 10 is effectively increased, thereby improving the heat exchange efficiency between the liquid medium and the air. When the temperature sensor 23 detects that the air temperature inside the heat exchange box 6 is lower than the preset temperature, the monitoring chip 24 is set to shut down the infusion pump 11 and the refrigerator 12, and start the electric heater 21, so that the electric heater 21 is self-heated. At the same time, the heat conduction ring plate 20 exchanges heat with the air passing through the annular heat exchange chamber 8 to increase the temperature, thereby increasing the working temperature inside the electric control box 2; When the air after heat exchange and temperature control is introduced into the electric control box 2 again through the air duct 9, the air duct 9 guides the air to directly impact the surface of the color-changing silica gel 17 on the top of the mounting plate 16, and the color-changing silica gel 17 intercepts and absorbs moisture in the air, thereby facilitating real-time adjustment of the internal working temperature of the electric control box 2, reducing the impact of temperature changes on the performance of the supercapacitor 3, and improving the stability and reliability of the system.

[0035] Reference Figure 1 and Figure 2 、 Figure 5The top of the electric control box 2 is symmetrically fixedly connected with a first guide plate 25, the output end of the air guide pipe 9 is set between the two first guide plates 25, and the top of the mounting plate 16 is symmetrically fixedly connected with a second guide plate 26, and the two first guide plates 25 are installed between the two second guide plates 26; Among them, the top of the mounting plate 16 is fixedly connected with a hydrophobic base layer 27, and the hydrophobic base layer 27 is installed between the mounting plate 16 and the color-changing silica gel 17. A plurality of hydrophobic grooves 28 are evenly arranged on the inner bottom of the hydrophobic base layer 27. A water collecting groove 29 adapted to the hydrophobic groove 28 is arranged at one end of the mounting plate 16. The inner bottom of the hydrophobic base layer 27 is inclined toward the water collecting groove 29. A drainage pump 30 is fixedly connected to the outside of the electrical control box 2, and the input end of the drainage pump 30 is connected to the water collecting groove 29.

[0036] During use, first, when the air guide pipe 9 discharges the temperature-controlled air into the interior of the electric control box 2, the temperature-controlled air flows along the guiding direction of the first guide plate 25 to the color-changing silica gel 17 on the top of the mounting plate 16, and along the surface of the color-changing silica gel 17, bypasses the first guide plate 25, flows between the first guide plate 25 and the second guide plate 26, and then flows into the interior of the electric control box 2, so that the air forms a curved flow path at the top of the color-changing silica gel 17, thereby extending the contact area between the air and the color-changing silica gel 17 and improving the dehumidification effect of the color-changing silica gel 17; After the color-changing silica gel 17 absorbs moisture in the air, a hydrophobic base layer 27 is provided to contact the moisture, so that the moisture condenses into water flow on the surface of the hydrophobic base layer 27 and flows into the interior of the water collecting tank 29 along the guiding direction of the hydrophobic groove 28. Then, the water flow accumulated in the water collecting tank 29 is discharged from the interior of the electrical control box 2 by starting the drainage pump 30, thereby effectively improving the dehumidification effect of the device, reducing the influence of moisture on the working performance of the supercapacitor 3, and improving the practicality of the device.

[0037] Reference Figure 1 and Figure 2 , the surface of the electric control box 2 is coated with an aerogel film.

[0038] When in use, by coating the surface of the electric control box 2 with an aerogel film, a heat insulating protective layer is formed on the surface of the electric control box 2, which effectively reduces the heat exchange inside and outside the electric control box 2 and improves the heat preservation effect of the electric control box 2.

[0039] The implementation principle of a four-motor control system in this embodiment is as follows: first, four motor controllers 13 are independently connected to control four air compressor bodies 1. At the same time, the four motor controllers 13 are connected to the circuit board 4 via a communication interface, so that the circuit board 4 can control the four motor controllers 13 to coordinate control. Then, after the first air compressor body 1 is started and stabilized by the circuit board 4, the next air compressor body 1 is started at a preset time interval. Four inverters 14 are provided to adjust the operating speed of the air compressor body 1 according to actual load demand. When additional power is needed, the supercapacitor 3 provides assistance to reduce the impact on the power grid. Then, as the usage time increases, the internal working temperature of the electric control box 2 changes. At this time, the humidity sensor 22 and the temperature sensor 23 are set to monitor the humidity inside the electric control box 2 and the temperature inside the heat exchange box 6 in real time respectively. When the temperature inside the heat exchange box 6 is higher than the preset temperature, the monitoring chip 24 is set to start the infusion pump 11 and the refrigerator 12, so that the infusion pump 11 draws the liquid medium inside the annular infusion tank 10 into the refrigerator 12 for cooling, and then introduces the cooled liquid medium into the annular infusion tank 10, thereby realizing the refrigeration cycle of the liquid medium. At the same time, the circulation pump 7 is started to draw the air inside the electric control box 2 into the annular heat exchange tank 8, and then cooperates with the air guide pipe 9 to introduce the air into the electric control box 2. At the same time, when the air passes through the annular heat exchange tank 8, heat exchange and cooling are achieved through the liquid medium inside the annular heat exchange tank 8 and the annular infusion tank 10; When the temperature sensor 23 detects that the air temperature inside the heat exchange box 6 is lower than the preset temperature, the monitoring chip 24 is set to shut down the infusion pump 11 and the refrigerator 12, and start the electric heater 21, so that the electric heater 21 is self-heated. At the same time, the heat conduction ring plate 20 exchanges heat with the air passing through the annular heat exchange chamber 8 to increase the temperature, thereby increasing the working temperature inside the electric control box 2; When the air after heat exchange and temperature control is introduced into the interior of the electrical control box 2 again through the air duct 9, the temperature-controlled air flows along the guiding direction of the first guide plate 25 to the color-changing silica gel 17 on the top of the mounting plate 16, and bypasses the first guide plate 25 along the surface of the color-changing silica gel 17, flows to between the first guide plate 25 and the second guide plate 26, and then flows into the interior of the electrical control box 2, so that the air forms a curved flow path at the top of the color-changing silica gel 17, thereby extending the contact area between the air and the color-changing silica gel 17 and improving the dehumidification effect of the color-changing silica gel 17.
