Problems solved by technology

The disadvantage is that there is a large error in measuring the volume of the auxiliary airbag by using a two-dimensional laser scanner
The disadvantage of this method is that the 3D laser scanner is expensive and heavy, and it is placed inside the airbag, which increases the buoyancy of the airship
The disadvantage of this method is that it needs to be filled with test gas to measure the volume of the airbag. Usually the volume of the airbag to be tested is large, but the quality of the test gas filled is small, and the measurement change is not significant. The accuracy of the gas concentration sensor is high, and engineering applications exist difficulty

Abstract

The invention relates to an airship auxiliary airbag volume monitoring device and method, and belongs to the technical field of aerostat volume measurement. By monitoring and controlling the gas flowand time in the inflation and deflation process of the airship auxiliary airbag and combining the temperature and pressure parameters of the airship auxiliary airbag, the air quality and the gas volume in the auxiliary airbag are dynamically calculated, and the volume change condition of the auxiliary airbag can be continuously monitored on line. The device and method well balance the measurementprecision and the measurement cost, meet the actual engineering application requirements, and can be popularized and applied to various aerostats with auxiliary airbag structures. The device can be realized by improvement on the basis of an existing air inflation and deflation valve of the aerostat and can replace an air inflation and deflation valve to achieve the air inflation and deflation functions of the auxiliary airbag of the aerostat.

Description

technical field [0001] The invention belongs to the technical field of aerostat volume measurement, and in particular relates to a volume monitoring device and method for an airship auxiliary airbag. Background technique [0002] An airship is an aerostat that is buoyant by a lighter gas, usually helium, including soft airships and rigid airships. The bladder is an important part of the airship, usually composed of the main airbag and the auxiliary airbag. The main airbag is filled with helium to form the streamlined shape of the airship and provide the buoyancy for the airship to rise. The auxiliary airbag is filled with air, which is used to adjust the internal pressure, maintain the shape of the airship, adjust the flight attitude and flight height, etc. [0003] During the flight altitude change of the airship, the auxiliary airbag is continuously filled and discharged with air through the air valve to adjust the volume of the auxiliary airbag. When the flight altitud...
