The working principle of the utility model is as follows:
1. the upper computer 1 starts a detection program, sends a control command to the first relay module 7 to close the first relay module, so that the power module 2 supplies power to the motor of the electronic vacuum pump 4, and starts the electronic vacuum pump 4. At this time, the second relay module 8 is in an off state, so that the electromagnetic pneumatic valve 11 is in a closed state, without deflation.
2. The electronic vacuum pump 4 starts to draw air in the vacuum tank 5, creating a vacuum. At this time, the pressure signal acquisition and transmission module 9 monitors the pressure signal of the vacuum tank 5 in real time, converts the pressure signal into a standard signal of 4-20 mA, and transmits the standard signal to the acquisition module 6. Meanwhile, the current signal acquisition and transmission module 12 monitors the current signal of the motor of the electronic vacuum pump 4 in real time, converts the current signal into a standard signal of 4-20 mA and transmits the standard signal to the acquisition module 6.

4. After the upper computer 1 draws and judges, the detection result is saved as a file, including a pressure-time curve, a current-time curve, a data table, an analysis report and the like. At the same time, the upper computer 1 sends a control command to the first relay module 7 to turn it off, thereby stopping the power supply module 2 from supplying power to the motor of the electronic vacuum pump 4 and turning off the electronic vacuum pump 4. Meanwhile, the upper computer 1 sends a control command to the second relay module 8 to close the second relay module, so that the power supply module 2 supplies power to the electromagnetic pneumatic valve 11, and the electromagnetic pneumatic valve 11 is opened to deflate.
