Problems solved by technology

Since fighter jets are aircraft with complex functions, the amount of software is huge, and there are sporadic finished product software version upgrades during the aircraft manufacturing stage, and the update of the software version inventory of the whole aircraft by the design unit is seriously lagging behind
In such a complex situation, it is difficult to control the version of the airborne software
[0003] Due to the serious lag of the version inventory provided by the design unit, and the actual production process, there are sporadic product software upgrades, the state is extremely chaotic, and it is impossible to automatically complete the comparison on the machine
At present, the identification of the aircraft’s software version can only rely on front-line operators to hand-copy records one by one, and then compare them with the list provided by the quality management department. The work takes about 3 hours for a single machine
The current identification method is time-consuming, highly dependent on personnel, prone to manual errors, and takes up a long time on the main line of aircraft production. The main line occupies about 1.5 hours, which seriously affects the progress of aircraft manufacturing.

Embodiment 1

[0040] As a basic embodiment of the present invention, the present invention includes a method for quickly identifying an airborne software version, comprising the following steps:

[0041] a. Display the software version page by page in the aircraft display and control screen, and record the display and control video data;

[0042] b. Play back the frame image of the airborne software version by frame interception;

[0043] c. Image recognition extracts the text information of the software version screen, and compares it with the preset character template library to form version information;

[0044] d. Compare the version information with the software version list, and synthesize the recognition results.

Embodiment 2

[0046] As a preferred embodiment of the present invention, the present invention includes a method for quickly identifying an airborne software version, comprising the following steps:

[0047] a. Display the software version page by page on the aircraft display and control screen, and record the display and control video data.

[0048] After the aircraft platform is powered on, power on the mission subsystem of the whole aircraft for the second time, and check the software version of the whole aircraft. Due to the large number of software version items for the whole aircraft, and the display content of the aircraft display and control screen is limited, it is necessary to select the software version page by page. The data recording system of the aircraft can automatically record the display and control video data, and store it in the airborne data storage card after being compressed. In order to reduce the video data size of the display and control as much as possible and sa...

Embodiment 3

[0065] As another preferred embodiment of the present invention, the present invention includes a method for quickly identifying an airborne software version, comprising the following steps:

[0066] a. Display the software version page by page on the aircraft display and control screen, and record the display and control video data.

[0067] b. Play back the frame image of the on-board software version captured by frame.

[0068] c. Image recognition extracts the text information of the software version screen, and compares it with the preset character template library to form version information. Specifically include:

[0069] c 1 . Store several captured frame images of the airborne software version in a fixed path, and use it as the original image for extracting the software version.

[0070] c 2 . Read in the original image and perform grayscale processing on the original image.

[0071] c 3 . Each grayscaled image is divided into rows, and each image corresponds to...

Abstract

The invention relates to the technical field of detection, in particular to a rapid identification method for an airborne software version, which comprises the following steps: displaying a software version page by page in an airplane display control picture, and recording display control video data; conducting playback and capturing airborne software version frame images frame by frame; extracting text information of a software version picture through image recognition and comparing the text information with a preset character template library to form version information; and comparing the version information with a software version list, and synthesizing an identification result. Through the identification method, main line work is reasonably converted into side line work, and the problems of long main line work time and high personnel dependence degree can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method for quickly identifying an airborne software version. Background technique [0002] The software version of the airborne electrical finished product is a significant reflection of the functional status of the fighter. The essence of the management and control of the airborne software version is the control of the functional state of the aircraft, and the identification of the airborne software version is the basic premise of the control. Because fighter jets are aircraft with complex functions, the amount of software is huge, and sporadic finished product software version upgrades are accompanied by the aircraft manufacturing stage, and the update of the software version inventory of the whole aircraft by the design unit is seriously lagging behind. In such a complicated situation, it is difficult to control the version of the airborne software. [0003] Due to the s...
