The recording and analysis of flight data is significant for the evaluation of flight state and the maintenance of avionics system. Aiming at recording and analysis requirements for multi-interface data of the IRS, the paper constructs an integrated, efficient and universal recording and analysis system. The general design of system and the design of subsystem are introduced in the paper. The realization methods of multi-interface data fusion, rapid data storage, data parse and data playback are discussed chiefly. The application practice has proved that the parse result is accurate, the cooperate conditions query is conveniently and the result of curve analysis and playback is intuitively. The system can service for the IRS data analysis and evaluation work, and it has great value for practical application.
