Utility aircraft airborne electronic system based on unified processing platform

Abstract

The invention provides a utility aircraft airborne electronic system based on a unified processing platform, comprising a flight display, a unified processing platform, an atmosphere navigation attitude acquisition unit, an operation control panel and a unified network bus which are interconnected, wherein the unified processing platform comprises a power supply module (PSM), a public processing module (CPM), a universal interface module (IOM), a radio frequency interface module (RFM), an audio frequency interface module (AUDIO) and an actuation control module (ACM), wherein the PSM inputs an airborne +28V DC normal power source and a +24V DC emergency power source which are then converted to a +12V DC power source required for the internal modules of the platform, the atmosphere navigation attitude acquisition unit and the operation control panel. The utility aircraft airborne electronic system based on the unified processing platform, provided by the invention, can further improve the system safety, can flexibly adapt to requirements of aircrafts of different types, and can realize function integration of different fields, such as utility aircraft avionics, flight control, flight management and air control.

Description

technical field [0001] The invention belongs to the professional field of airborne systems and equipment, specifically relates to the general aircraft airborne electronic system technology, and uses the general aircraft as the application object, and proposes a general aircraft airborne electronic system architecture based on a unified processing platform. Background technique [0002] The on-board electronic system of a general-purpose aircraft refers to the electronic system required to support the completion of normal flight tasks, generally including comprehensive display, parameter acquisition, communication, navigation, surveillance, flight control, recording, maintenance and alarm functions. [0003] The airborne electronic system is the eyes, ears, brain and nerves of general-purpose aircraft. It can be said that its advanced level is an important symbol of the technical development level of general-purpose aircraft. Without advanced airborne electronic systems, there...

AI Technical Summary

Problems solved by technology

[0004] a. The degree of integration is still insufficient, and it is difficult to provide further information that is conducive to the integrated judgment of flight safety;

[0005] b. The physical form is still independently configured, and the functions of avionics, flight control, flight management and air traffic control are still realized by independent equipment, and the degree of integration is difficult to improve. The increase of functions requires the addition of independent equipment, resulting in relatively high development costs ;

[0006] c. Poor application flexibility, the system cannot be flexibly adapted to different types of general-purpose aircraft, and a large change is required for specific aircraft to meet the needs of the aircraft
