Integrated avionic system

Abstract

The invention discloses an integrated avionic system capable of enhancing the system integration degree and guaranteeing the safety and reliability of an aircraft while the total weight is reduced. The integrated avionic system comprises a first integrated display control unit and a second integrated display control unit, a first data interface unit and a second data interface unit, a dual-redundancy atmosphere data system, an INS / GNSS integrated navigation system, an integrated radio system, a head-up display unit and a cockpit monitoring system; the integrated display control units are arranged as an integrated structure with a processor and a display, are used for displaying a flying state and navigation information and are used for receiving a control operation instruction of a pilot by using a touch screen and a physical key; the data interface units are used for independently performing data collection, data processing and data distribution, wherein the data collection comprisesobtaining data generated by each airborne equipment and state data of each airborne equipment by using an RS-422 bus and an Ethernet network; and the data processing comprises unpacking and packing the collected data according to the setting of target equipment.

Description

technical field [0001] The invention relates to the technical field of avionics equipment, in particular to an integrated avionics system. Background technique [0002] Modern aircraft usually use a unified processor to uniformly process the information of various avionics equipment on the aircraft, combine devices with the same or similar functions into one component, comprehensively display relevant parameters on the display, and display them in various avionics The relevant information is transmitted through the on-board data bus, so that the performance of all avionics on the entire aircraft can reach a higher level. Such a system is called an integrated avionics system. [0003] The Chinese invention patent application with the application publication number CN106789499A discloses an integrated avionics system for light and small aircraft, which includes a navigation subsystem, a communication subsystem, and an indication / record subsystem; its integrated processor inclu...

Problems solved by technology

[0004] However, the system has some low integration levels and some unreasonable integration (for example: 1. It uses two independent small-sized displays, the main flight display PFD and the multi-function display MFD, for human-computer interaction, instead of using a whole large 2. The GPS receiver is integrated in the radio navigation control system, but not in the strapdown attitude system, and the GPS information cannot be introduced into the strapdown attitude system for correction ;3. The air data computer and the strapdown attitude system have not interacted, and the calculation of wind speed, wind direction and other information cannot be performed; 4. The transponder, radio compass ADF, VOR / LOC / GS receiver, pointing beacon machine and measurement The radio equipment such as the distance meter is not integrated into a whole device, resulting in too many devices and complicated wiring on the aircraft), and the air data system and the strapdown attitude system, which are closely related to flight safety, have not adopted redundant design, resulting in system safety and lower reliability issues
