Design of a new aviation proactive maintenance support system

A new aviation proactive maintenance support system was put forward based on the Beidou satellite data link. The “Air-Ground” two-direction data processing method was adopted to carry out the on-line interpretation of flight parameters, the proactive maintenance support and the real-time operation of the safety monitoring system. The basic condition of proactive maintenance support, aircraft real-time status monitoring and Beidou short message system, especially the overall structure and advantages were analyzed. And then the working principle and the equipment structure of three parts, which include the airborne part, the ground processing system and the Beidou satellite data transmission devices were demonstrated as well.
