Abstract

The invention discloses a differential pressure measuring device and a differential pressure measuring method based on solenoid valve control. The differential pressure measuring device comprises an electromagnetic valve, a pressure sensor, air tubes, a data processing module and a data line. With the differential pressure measuring device and method of the invention adopted, the problem of maladjustment in internal and external differential pressure measurement of an aerostat capsule existing in a traditional measuring device can be effectively solved, and a real-time requirement under a special working environment can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of differential pressure measurement, and in particular relates to the measurement of the internal and external pressure differential of aerostat capsules such as tethered balloons and airships. Background technique [0002] Aerostats include airships and tethered balloons, which are lighter-than-air aircraft. The basic principle is to fill helium in soft, semi-soft or hard capsules to generate buoyancy to overcome their own weight and achieve flight from the stratosphere to near the ground. Maneuvering in the air range or staying in the air at a fixed point. The capsule is an important component of the aerostat. In the complex and changeable external environment, it is necessary to strictly control the internal pressure of the capsule to ensure that the aerostat maintains a good aerodynamic shape in the harsh natural environment, thereby ensuring its normal work. In order to achieve strict control of the ...
