The onboard system is to provide warning information to pilots, and the ground system provides maintenance suggestions for ground maintenance personnel, and provides planning for maintenance support.


  • The processor runs at a high speed, reaching 800MIPS;
  • Large-capacity data storage and management functions with high reliability;
  • A cache card to be quickly inserted and removed to realize fast and convenient download of EMU data;
  • Acquisition and processing of the signals of vibration, speed, lubricating oil level and lubricating oil wear debris;
  • Sending data to the aircraft and communicating with the ground subsystem;
  • Receiving the engine parameter data of the engine digital electronic controller and the flight parameter data of the aircraft;
  • Automatic or manual event recording
  • API function interface for application software development.


  • Civil and commercial aviation engines, etc.
