(7) During air exhaust, the flow sensor (14) is controlled by the control keyboard (7) to work to acquire flow information at the air inlet and outlet pipe (3) in real time and transmit the flow information back to the control host (5), the control host (5) converts the flow information into real-time air output and displays the real-time air output on the display screen (6), and therefore effective statistics and allocation of air production supply are facilitated;
(8) In the whole gas making and supplying process, the infrared camera (22) is controlled by the control keyboard (7) to work to acquire the video information of the working components in the machine body (4) in real time and display the video information on the display screen (6) in real time, so that the working state of the components in the machine body (4) can be conveniently known, and problems can be found and maintained in time.
