Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of explosive decompression, and in particular to an explosive decompression control method based on a self-attention mechanism. Background Art
[0002] Explosive decompression is an extreme pressure change phenomenon, which usually occurs in the fields of aerospace, deep-sea diving, etc. Its characteristic is that the pressure inside and outside the cabin is quickly balanced in a very short time, which can easily cause serious damage to the personnel and equipment in the cabin. China is one of the countries with the largest number of civil airliners in the world, and there are many cases in which the safety of pilots and passengers is endangered due to extreme weather or aircraft failure during flight. The explosive decompression training cabin is designed to simulate the rapid loss of airtightness and pressure in the cabin of civil aircraft during high-altitude flight. The simulation process requires high accuracy of explosive decompression time. The explosive decompression time in the explosive decompression training cabin is mainly completed by presetting the valve opening. There are two levels of valves on the throat of the pipeline: the first level is a fast-opening valve, which is closed in the preparation stage; the second level is a pneumatic eccentric butterfly valve and other valves. According to the time requirements of explosive decompression, the opening is preset by the control program in the preparation stage and then fixed. At the beginning of explosive decompression, the first-level valve is opened quickly to complete the explosive decompression. At present, the control of explosive decompression time is completed by recording the preset value of the valve opening during the debugging phase. However, the above method relies on preset programs and simple feedback mechanisms, and lacks the ability to dynamically analyze and adjust real-time data. In the actual operation process, due to factors such as changes in the system environment and the deviation of the valve opening, the explosive decompression time may be inaccurate, affecting the operation process of the system.

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0036] In this embodiment, if Figure 1-Figure 4 As shown, a method for controlling explosive decompression based on a self-attention mechanism includes an explosive decompression control system based on a self-attention mechanism. The control system includes sensor devices 200 arranged on both sides of a collection cabin 100. The sensor device 200 is responsible for real-time and accurate collection of physical quantities affecting the decompression process, such as pressure changes and ambient temperature, and has good sensitivity and anti-interference capabilities to ensure the accuracy and reliability of data collection. A pipeline throat 110 is arranged on one side of the collection cabin 100, and a primary valve 120 and a secondary valve 130 are arranged on the outside of the pipeline throat 110. A monitoring device 300 for monitoring the opening time of the primary valve 120 and the opening degree of the secondary valve 130 is also arranged on one side of the pipeline throat 110. The monitoring device 300 can record the valve action state and parameter changes with high precision for subsequent data. The analysis and control strategy adjustment provide a key basis. The explosive decompression time is affected by factors such as the opening of the secondary valve 130 in the pipeline throat 110, the pressure conditions before the explosive decompression inside and outside the collection cabin 100, the ambient temperature, and the opening time of the primary valve 120. The data of the above factors can be collected through the sensor device 200 and the monitoring device 300. The central controller 400 also includes a central controller 400. The central controller 400 communicates with the sensor device 200 and the monitoring device 300 through the network. The central controller 400 realizes real-time interconnection with various components such as the sensor device 200 and the monitoring device 300 through a stable network communication mechanism, receives data information from the sensor device 200 and the monitoring device 300, and is convenient for using advanced algorithms to process and analyze data to formulate an optimal decompression control strategy.
