Meteorological sounding pod control method for high-altitude detection

Abstract

The invention belongs to the field of high-altitude throwing of meteorological sondes, and particularly relates to a meteorological sounding pod control method for high-altitude detection, which comprises the following steps that: 1, the whole throwing stage is subdivided, and preparation before throwing is carried out; 2, in the meteorological sonde preparation process, activation operation and ephemeris filling and positioning control of a meteorological sonde are carried out, and in the throwing control process, cabin door opening, ejection mechanism releasing and cabin door closing are carried out; 3, preparation is also carried out, the preparation stage of each module, the preparation stage of the meteorological sonde and the release control stage are subdivided and further analyzed, and parallel processing is performed under the condition of non-interfering work; 4, essential elements of the throwing stage are extracted, the throwing stage is independently controlled, and only the cabin door needs to be opened, and an ejection module works; and 5, the cabin door is opened, and the working time of the ejection module is completed within 3 s.

Description

technical field [0001] The invention belongs to the field of high-altitude delivery meteorological radiosondes, and in particular relates to a method for controlling a meteorological radiosonde pod used for high-altitude detection. Background technique [0002] The weather sounding pod is a load device that can load the weather sonde, transport it to high altitude by aircraft, and control it to be released from the cabin. The meteorological radiosonde falling in the sky collects meteorological data such as temperature, humidity and air pressure and sends them back to the ground testers to achieve the purpose of meteorological detection. In recent years, with the development of meteorological detection such as typhoon detection, it is required that the meteorological sounding pod can efficiently, controllably and safely complete multiple meteorological radiosonde deployment-detection tasks at one time, and a good meteorological sounding pod control The method can improve the...

AI Technical Summary

Problems solved by technology

[0004] 1) There are too many serial steps in the control process of the whole launch stage, as long as one step fails, it will affect the failure of the entire launch result, thereby affecting the subsequent launch tasks of other meteorological radiosondes

[0005] 2) The launch response time of the meteorological radiosonde is too long (about 1 minute), which affects the safety of aircraft launch

That is, at T0, the operator judged that the current launch conditions were safe and sent a launch command according to the launch safety factors such as the aircraft attitude, but the actual situation was that the weathersonde went through the entire launch stage after T0+1min, and the actual launch left the aircraft. However, it is uncontrollable whether the safety elements of the aircraft launch after T0+1min meet the criteria, and there are safety risks
