[0023] like Figure 1As shown, an avionics integrated testing and management system includes a test main control system, a data management center, and a test simulation network.
[0024] The test control system consists of an industrial computer, a monitor, a keyboard and mouse, as well as main control software and script management software.
[0025] The industrial control computer and monitor provide the necessary development and operation environment and external interfaces for the main control software and script management software.
[0026] The main control software consists of a process management module, a network monitoring module, and a display module. It connects to the test simulation network via an Ethernet interface to issue control commands and monitor communication data. The definition of the communication interface is implemented by the dedicated software of the test simulation network.
[0027] The main functions of each module are as follows:
[0028] Process Management Module: Manages the entire experimental process by issuing control commands through the experimental simulation network, including commands for initialization, running, pausing, and ending; controlling script selection and loading, execution steps of experimental items, and generation of test reports;
[0029] Network monitoring module: Real-time monitoring of the network status and communication data of each node on the test simulation network, parsing and displaying the monitoring data according to the test simulation network interface control file, helping developers to debug the test environment and helping users to grasp the working status information of each test equipment;
[0030] Display module: It rationally divides the screen display area, provides users with detailed operation prompts and current data interpretation results; and provides control buttons and dialog boxes for switching on / off the test equipment software, controlling the test process, modifying flight simulation parameters, and displaying network monitoring data.
[0031] The script management software provides dedicated script editing functions during the test preparation phase, guiding users to refine the initial conditions, operation prompts, and test criteria of the test script. Finally, it verifies the script and outputs it to a shared folder, which can be accessed by simulation and test nodes within the network according to the test procedures. The software must ensure that the output test script format conforms to XML syntax specifications, that the initial conditions can be recognized by the test equipment, and that the test criteria meet the value range specified in the avionics system interface control document.
[0032] The data management center consists of a disk array, a monitor, a keyboard and mouse, as well as product information management software, test data management software, data retrieval software, and test report output software.
[0033] The disk array and monitor provide the necessary development and operation environment, large amount of data storage space, and external interfaces for the product information management software, test data management software, data retrieval software, and test report output software.
[0034] The product information management software has no communication interface with the outside world. The test report output software connects to the test simulation network via an Ethernet interface to receive the criterion test results reported by each test node of the integrated test system. The definition of the communication interface is implemented by the dedicated software of the test simulation network. The test data management software is based on the FTP protocol and receives process record files uploaded by each test system via an Ethernet interface.
[0035] The main functions of each software are as follows:
[0036] Product information management software: Used when products enter and exit testing. It registers product history and maintenance information through a dedicated database, including product name, quantity, model, entry and exit dates, and fault descriptions. The software also needs to provide users with product information retrieval and export functions based on various criteria.
[0037] Test data management software: After the test is completed, it receives the process data recorded by the integrated test system through the test simulation network. In the post-test analysis phase, users can view the test data by steps, time, equipment, and other elements. The playback format is data source code or physical meaning, and the data can also be converted into curves, allowing users to directly view the data change process, gain a macroscopic understanding of the signal interconnection relationships between all devices, and understand the working principle of the avionics system;
[0038] Data retrieval software: It can quickly query data tables according to user needs by using various combinations of conditions such as step number, time, device, and data type, and draw signal change curves based on the values.
[0039] Test report output software: Used during the test, it receives the criterion detection results reported by the integrated test system through the test simulation network, including GJB289A bus data, FC bus data, etc., and provides real-time feedback to the user on the operational conclusions of each step of the test. After the test, it generates a test report based on the test script content and the above interpretation results, and gives the test conclusions.
[0040] The experimental simulation network consists of an Ethernet switch, simulation interface definition software, and a network communication library. It utilizes a packaged network communication library paired with a high-performance Ethernet switch to construct an information transmission network for control commands, simulation data, and test data. The main functions of each software component are as follows:
[0041] Simulation interface definition software:
[0042] It can set the name, node ID, IP address, etc. of network nodes, and finally generate network node configuration files for use by the network communication library; it can define the communication interface between each node using a dedicated editing tool, and set attributes such as variable name, type, sender, receiver, message block ID, etc., and finally save it to a header file, which is output to each network node for development and debugging.
[0043] Network communication library: It encapsulates a set of functions in the form of a dynamic link library, which, together with node configuration files and communication interface header files, enables data communication, data monitoring, time synchronization and status monitoring functions.
[0044] Operating procedures for product testing:
[0045] Connect the power supplies to the industrial control computer of the test main control system, the disk array of the data management center, the Ethernet switch, and the relevant test equipment. After the test main control system and the data management center enter the Windows system, click on the main control software of the test main control system and the product information management software and test report output software on the desktop of the data management center. In the product information management software, register the product's history and maintenance information, including product name, quantity, model, date of entry and exit from the factory, and fault description.

Click the "Device Status" button to bring up the device status interface, select the device to be used, and remotely start its test software. On the main interface, click the "Script Selection" button. Select the script to be tested and load it, then click "Run". The system will automatically start the test. At this time, the network monitoring module in the main control software monitors the network status and communication data of each node on the test simulation network in real time, and parses and displays the monitoring data according to the test simulation network interface control file. Meanwhile, the test report output software in the data management center receives the judgment test results reported by the integrated test system through the test simulation network, including GJB289A bus data, FC bus data, etc., and provides real-time feedback to the user on the operation conclusions of each step of the test. After the test is completed, click "End" in the main control software, and the test report output software in the data management center will generate a test report based on the test script content and the above judgment results, and give the test conclusions.
