[0018] The electromechanical bus transmits data from the onboard electrical parameter collector, the electrical parameter collector obtains data from the electrical parameter system, and the avionics bus transmits data from the electromechanical system;
[0019] The core machine is connected to the avionics bus and the electromechanical bus respectively, and has a conversion instruction function that can convert the data transmitted by the secondary network into the data transmitted by the primary network, and call the storage history and airborne parameter data.

[0024] Data that has not been modified in human-computer interaction mode is stored as normal data in normal storage mode and is stored for 10 minutes; data that has been modified in human-computer interaction mode is stored in fault storage mode, marked and time-stamped, and stored for 2 minutes.

[0026] By using the human-machine interaction interface of the aircraft's avionics system and data transmission and interaction through a double-layer network, data playback of the electrical system can be achieved, making it easier for ground crew to maintain the aircraft and improving efficiency.
