step S201: the ventilation time is obtained from a first preset time period of the representative gas-using apparatus.
A timing module may be provided at the representative gas use apparatus by which the ventilation time of the representative gas use apparatus within the first preset time period is detected. In an application scenario, the first preset time period may be 10 minutes, and the representative gas-using device ventilation time is detected to be 120 seconds within 10 minutes.

Wherein the representative total flow may be a representative total flow under a standard condition, specifically, step S202 may include: and obtaining the representative total compressed flow, the pressure, the temperature and the instantaneous flow of the compressed gas required by the representative gas utilization equipment, and calculating the representative total flow of the representative gas utilization equipment under the standard condition based on an ideal gas state equation.
The ideal gas state equation is: (P1Q 1)/t1= (P Q)/t. Wherein P1 is the air pressure at standard conditions, which is approximately equal to 101.325kpa; q1 is the total flow of compressed gas under standard conditions; t1 is the air temperature under standard conditions, equal to approximately 273.15K; p is the measured pressure, Q is the measured accumulated flow, and t is the measured temperature.
