Description
Technical Field
The invention belongs to the field of high-altitude released meteorological sondes, and particularly relates to a meteorological sounding nacelle control method for high-altitude detection.
Background
The weather sounding nacelle is a load device which can load a weather sounding device, transport the weather sounding device to high altitude through an airplane and control the weather sounding device to be thrown out of a cabin. The meteorological sonde falling in the air collects meteorological data such as temperature, humidity, air pressure and the like and transmits the meteorological data back to ground testers so as to achieve the purpose of meteorological detection. In recent years, with the development of meteorological exploration services such as typhoon exploration, a meteorological sounding pod is required to be capable of efficiently, controllably and safely completing a plurality of meteorological sounding instrument launching-exploring tasks at one time, and a good meteorological sounding pod control method can improve task completion efficiency and is also an important means for guaranteeing flight safety.
The existing control method for the meteorological sounding pod generally uses only one step to perform a series of control processes such as lock pin control, transportation control, ejection control, cabin door control and the like in series, and is specifically shown in fig. 1 below. Thus, with a single step, the simple control process of tandem has the following drawbacks:
1) the control process of the whole launching stage has too many serial steps, and as long as one step fails, the whole launching result can be influenced, so that launching tasks of other follow-up meteorological sondes are influenced.
2) The response time of the release of the weather sonde is too long (about 1 min), which affects the release safety of the airplane. Namely, at the time of T0, an operator judges that the current launching condition is safe and sends a launching command according to launching safety element criteria such as airplane attitude and the like, but in the practical situation, the weather sonde passes through the whole launching stage after T0+1min, the weather sonde is actually launched away from the airplane, and whether airplane launching safety elements after T0+1min meet the criteria is uncontrollable, so that safety risk exists.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a meteorological sounding nacelle control method for high-altitude detection.
