Abstract

The invention belongs to the technical field of computers, and particularly relates to an airborne heterogeneous network data recording system which comprises a data acquisition module, a data transmission module and a data recording module. The system can collect and record bus data and key signals in an airborne heterogeneous network in real time, check internal hardware of equipment through a power-on self-test mechanism, ensure that the equipment has enough storage space to store data every time the equipment is powered on by utilizing space management during power-on, and by adopting a redundancy write-in mechanism, reliable data real-time storage service is provided, and a basis is provided for problems occurring in the aircraft flight training process through data playback display on the ground.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to an airborne heterogeneous network data recording system. Background technique [0002] During the flight of the aircraft, the airborne equipment is interconnected through various buses, and various types of data are generated accordingly. In order to facilitate post-flight data processing and analyze the performance and failure of the airborne equipment, it is necessary to Record all kinds of data exchanged between airborne equipment. Due to the inconsistent bus types and formats for the interconnection of aircraft on-board equipment, the network environment is extremely complex, and the amount of data to be recorded is large, so there is an urgent need for an aircraft with uniform data format, high reliability, and convenient data analysis after flight. Load heterogeneous network data recording system. Contents of the invention [0003] (1) Technical problems t...
