It collects and processes bus and video data during the test process, and compares and judges whether the current operation step inspection content is qualified according to standard data and process requirements. It can effectively improve the accuracy of ground joint test of avionics system and reduce the occurrence of human errors. Specifically:

[0020] The test management equipment includes a computer, a network switch, a display and test management software;

[0021] The image acquisition and judgment device includes a second computer, a second display, and an image acquisition device;

[0022] The bus data acquisition and judgment device includes a computer 3, a display 3 and bus data processing software;

[0023] The result file generating device comprises a computer 4, a display 4 and result file generating software.

[0024] The computer 1 and the display 1 are used to provide a running environment and an operation interface display for the test management software.

[0025] The process file of the test management software is processed by the process flow module to generate a test script, which contains information such as specific operation steps, image detection, bus data standard values, etc. The test script provides the operation content display for the human-machine interface module. The human-machine interface module provides human-machine interaction function. The tester selects the test script, operation steps, etc. through the human-machine interface. The human-machine interface module displays according to the tester's selection and transmits the test script and operation step information to the network communication module, which forwards it to other devices.

[0026] The network switch is used to realize information transmission between the test management equipment, the image acquisition and judgment equipment, the bus data acquisition and judgment equipment, and the result file generation equipment.

[0027] After receiving the transmitted test script and operation step information, the image processing software captures the test video screen, determines the type of element to be detected, selects the corresponding image processing and recognition method according to the element type, processes the image, compares and analyzes the image processing and recognition result with the standard value, determines whether the current test screen is qualified, and outputs the result to the result file generation system.

[0028] The test management software includes a process flow for converting process test documents into process test scripts, a network communication module for broadcasting the current test script and test step information to the image acquisition and judgment device and the bus data acquisition and judgment device via the network, and a human-machine interface for providing script selection, test start, test end, and operation step guidance display functions.

[0029] The bus data processing software collects bus data in real time for analysis. After receiving the test script and operation step information, it retrieves the information that needs to be tested in the current operation step, extracts the current bus analysis result from the real-time bus data, compares it with the standard value to determine whether it is qualified, and outputs the result to the result file generation system.

[0030] The second computer and the second display provide an operating environment and an interface display for the image processing software.

[0031] The image acquisition and judgment device includes an image acquisition device and image processing software.

[0032] The image acquisition device includes a video format converter that receives four groups of on-board video signals through a test cable and converts them into DVI format and then transmits them to a video matrix, and a video matrix that selects and controls a group of video signals to be output to a computer for image processing according to test requirements.

[0033] The image processing software is used to capture the current video screen, retrieve the element information that needs to be tested according to the test script and test step information transmitted by the test management device, analyze and process the graphics, numbers, characters, and color elements in the screen, determine whether the current display meets the process requirements, and transmit the test results to the result file generation device.

[0034] The computer three and the display three are used to provide a running environment and an interface display for the bus data processing software, and are equipped with a 1553B bus card, and can be used as a bus monitor to monitor and receive bus information.

[0035] The bus data processing software can parse the 1553B bus data according to the interface control file, and retrieve the bus data currently to be tested according to the test script and test step information transmitted by the test management device, compare the parsing results with the standard data, and transmit the test conclusions to the result file generation device.

[0036] The computer 4 and the display 4 are used to provide an operating environment and an interface display for the result generation software.

[0037] The result file generation software retrieves the script result file template according to the received test script information, fills the image detection results and bus data detection results into the result file template according to the received test steps, and saves the file after naming it in the prescribed format at the end of the script test.

[0038] After receiving the test script information, the result file generation software calls the corresponding result file template, fills the received image processing results and bus data processing judgment results into the result file template according to the received operation step information, and names and saves the result file after completing the script test.
