Aerostat capsule ground automatic inflation control method and device

Abstract

The invention discloses an aerostat capsule ground automatic inflation control method and device. The automatic inflation control method comprises the steps of: 1, collecting a real-time differentialpressure value in a capsule; 2, comparing the real-time pressure difference value with a preset expected pressure difference value, calculating a difference value between the real-time pressure difference value and the expected pressure difference value, and changing a control signal of a frequency converter according to the difference value, so that the frequency converter changes the rotating speed of a fan for inflating the bag body until the difference value reaches a set change range; and after the difference value reaches the set change range, controlling the difference value to be stabilized within the set change range within the set duration T. According to the invention, the automation of the inflation and pressurization operation of the aerostat capsule can be realized, the pressure difference value of the capsule after inflation molding can be accurately controlled, and the pressure difference value of the capsule is stabilized within a small change range for a long time; the aerostat capsule ground automatic inflation control method and device are relatively simple in composition, compact in structure, good in portability, high in practicability, convenient to operate,high in working reliability and low in fan working energy consumption.

Description

technical field [0001] The invention belongs to the technical field of aerostat capsule inflation control, and in particular relates to an aerostat capsule ground automatic inflation control method and device. Background technique [0002] The aerostat is an aircraft that mainly relies on static buoyancy to overcome its own weight and lifts into the air. Compared with other aircraft, it has many unique application advantages such as long time in the air, high cost-effectiveness, large load capacity, and good safety. , has a wide range of uses and good application prospects in many military and civilian fields such as transportation, environmental monitoring, remote sensing communication, information transmission, sightseeing and tourism. The main components of traditional aerostats such as airships and tethered balloons are one or more capsules made of flexible composite materials with good airtightness and load-bearing capacity. [0003] Before the ground performance test,...

Problems solved by technology

[0004] This method of inflating the bladder is simple, but it requires a high number of operators, skills, sense of responsibility, and coordination and proficiency, especially when large-flow fans and high-pressure fans are used to inflate the bladder. The bladder is inflated too much, and the pressure difference is too large to burst. Moreover, it is difficult to maintain the pressure difference of the bladder within a small range for a long time with this inflation control method, and the energy consumption of the fan is high.
