Problems solved by technology

If all flight data is stored in this cycle, the data file will also be too large
If you record for 2 hours, the file may exceed 2G, so if you read all the data into the memory, an exception will be thrown, so you can only reduce the amount of stored flight data

Abstract

The invention relates to a method of realizing data playback of an aircraft simulator, which belongs to the technical field of aircraft simulators. The method is characterized by comprising steps of communication configuration, data storage and data playback. In the communication configuration, a system in which flight data circulate in the aircraft simulator comprises a flight simulation computer, an instructor console, a virtual scene and an analog cockpit, the networks of all computers in the system are configured in the same network segment, and the data communication adopts an Ethernet mode. In the data storage, the stored flight data are divided to two types, the data in the first type are stored in a 10-millisecond cycle and comprise aircraft position and attitude information, the data in the second type are stored in a 100-millisecond cycle and comprise pilot control and subsystem status data, and the flight simulation computer receives a data storage instruction and calls a data storage module to start recording. In the data playback, the flight simulation computer receives a data playback instruction and calls a data reading module, and a file is read in a binary format.

Description

technical field [0001] The invention relates to a method for realizing playback of aircraft simulator data, belonging to the technical field of aircraft simulators. Background technique [0002] During the training process of pilots using aircraft simulators, functions such as pilot teaching lecture ratio and flight quality evaluation are very important. Through the playback function of the flight simulator, the data package is called in the background, so that the recorded data can be played back in a real way, and the virtual scene, cockpit system, instructor console and flight data are combined to reproduce the pilot's control, aircraft flight status, and flight data. Trajectory, and fault information and other data. At the same time, the flight parameters can be analyzed through the data package, and the changes of various flight parameters during the flight of the aircraft can be studied. It is also beneficial to the debugging work of the designer in the process of de...
