During the self-checking of the software control system during the startup operation, the real-time flow value and the electronic flowmeter mark transmitted from the lower computer are accumulated continuously for 10 times through the self-defined communication protocol with the lower computer. When the control system judges that the 10 accumulated values of the flowmeter in the communication no-alarm state are the same, one global flag is set to be effective. The control system refreshes language information about the flow meter in the software through the mark, displays the position and the graphic icon. And after the control system enters the main interface after self-checking is finished, the flowmeter is displayed to be in a corresponding shape. The interface displays 3 combination modes, oxygen and air combination, oxygen and nitrous oxide combination, oxygen and air and nitrous oxide combination, and configuration of oxygen and nitrous oxide matching mode. In this combination, the interface display of the control system also includes a combination mode of the economic indicator.
