Method for calculating high-pressure air resource consumption of wind tunnel group

The invention is applicable to the technical field of wind tunnel tests, and provides a wind tunnel group high-pressure air resource consumption calculation method. The method comprises the followingsteps: constructing a topological structure model; establishing a monitoring system; acquiring the state of a test wind tunnel in the wind tunnel group, and acquiring the state of a high-pressure airsystem; obtaining a tank group pressure difference consumed by the test wind tunnel; updating the topological structure model; traversing the updated topological structure model to obtain the guaranteed volume of the wind tunnel being tested; and calculating high-pressure air resource consumption of the wind tunnel under test through a differential pressure method. The high-pressure air system comprises a high-pressure unit, a high-pressure tank group, an air conveying main pipe, air conveying branch pipes and valves. According to the method, the actual physical topological structure relationship between the high-press
