To ensure accurate and efficient communication between devices in an Ethernet environment, comprehensive testing is necessary. Communication testing verifies whether communication protocols are executed correctly, data transmission is accurate, and adaptability to network topology changes. However, current testing methods, lacking data loggers, cannot fully verify the functionality of ground maintenance equipment. Summary of the Invention

[0018] This application provides a method for testing interactive communication between a simulator and a recorder in an Ethernet environment.
[0019] like Figure 1 and Figure 2 As shown, a method for testing interactive communication of a simulated recorder in an Ethernet environment includes the following steps: A simulation recorder is established, which has maintenance function modules and real-time monitoring modules that simulate the maintenance functions and real-time monitoring functions of a real recorder. The communication of the simulation recorder uses TCP+UDP to verify the maintenance functions and real-time monitoring functions.
[0020] Configure the simulator's model according to the onboard configuration file. The onboard configuration file is a hexadecimal file; it includes the model number, configuration version, and fault word commands. Follow the simulator's internal communication protocol to determine the port number, IP address, and command word format for communication.
[0021] When the model of the simulator recorder matches the model of the ground maintenance equipment, the ground maintenance equipment will detect the recorder connection and output the corresponding model of the recorder.
[0022] Establish a link between the emulator and ground maintenance equipment via a designated Ethernet port.
[0023] Functional testing employed TCP protocol for data download, data history reading, and maintenance self-check functions, while UDP protocol was used for real-time monitoring function testing.
[0024] The simulator acts as the server, and the ground maintenance equipment acts as the client. Data to be sent to the client is pre-prepared and stored in a designated file directory. Upon receiving a data transmission request from the client, the data is transmitted via Ethernet. During testing, it is first determined whether the communication protocol between the client and server is TCP or UDP, which determines whether the client sends commands via broadcast or point-to-point. The corresponding airborne and ground configurations are read to maximize the simulator's effectiveness. When the simulator model successfully matches the corresponding airborne configuration, a configuration read success statement and the simulator model are output on the test equipment's main interface. The server establishes a corresponding listening thread to listen for communication request commands from the client. Upon receiving a communication connection establishment command from the client, the server sends a successful response command and establishes a connection. After successful connection establishment, the client sends commands according to the user's needs, and the server responds with a reply command. The client and server communicate bidirectionally, providing different responses based on different commands. Depending on the logger model, the server establishes a listening thread to monitor the commands sent by the client and responds accordingly. After receiving the feedback from the server, the client executes the corresponding functional test operations and outputs the test results, completing the single-item functional test. This process is repeated until the functional verification is complete.
[0025] The steps for establishing a link between the simulator and ground maintenance equipment include: The simulation recorder establishes a corresponding listening thread to listen for communication request commands issued by the ground maintenance equipment.
[0026] The simulation recorder acts as the server, with a pre-defined IP address and port number written in the configuration file. When the listening thread starts, the background socket will bind to the corresponding port and listen for external client access requests, with the ground maintenance equipment acting as the client.
[0027] During functional testing, the TCP protocol was used for real-time command-line interaction to verify the recorder's maintenance functions.
[0028] The steps of functional testing include: To verify the 1394B bus heartbeat word detection of the real-time monitoring module, a command word request is first sent via TCP protocol. After receiving the command from the maintenance software on the ground maintenance equipment, the TCP connection is requested to be closed. After the TCP connection is closed, data transmission is performed in the background using UDP protocol. At this time, the changes in the 1394B bus heartbeat word are observed through the real-time monitoring module of the maintenance software on the ground maintenance equipment. When the 1394B bus heartbeat word beats normally, the real-time monitoring function verification is completed, and real-time monitoring is exited to continue testing other functions. When the real-time monitoring module exits, the UDP protocol terminates, the TCP protocol is re-established, the simulation recorder software is re-initialized, and other functions of the maintenance software can be verified again.
[0029] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
