Extendable core system for universal avionics system

Abstract

The invention provides an extendable core system for a universal avionics system, belonging to the design field of comprehensive avionics systems. The extendable core system comprises comprehensive treatment units, display units, an audio selecting and controlling unit and a motor parameter interface unit, wherein interfaces are reserved for all the parts; the comprehensive treatment units comprise a comprehensive treatment unit A and a comprehensive treatment unit B which are used for transmitting decision signals between each other; the decision signals are used for determining whether the comprehensive treatment unit A and the comprehensive treatment unit B normally work; when both the comprehensive treatment unit A and the comprehensive treatment unit B work normally, arbitration and treatment on the same data in the two comprehensive treatment units are carried out by taking the comprehensive treatment unit A as the main component and the comprehensive treatment unit B as the minor component; and the display units comprises a display unit A and a display unit B. In the invention, a comprehensive system framework is adopted; aiming at the universal avionics system, the extendable core system is extended and carries out cutting according to different application requirements based on supporting of a unified core system.

Description

technical field [0001] The invention belongs to the design field of an integrated avionics system, and relates to an expandable core system of a general avionics system. Background technique [0002] In recent years, with the continuous and rapid development of China's aviation industry and the gradual advancement of the marketization process, the general aviation market structure has undergone major changes. The market demand has gradually expanded from government departments or state-owned enterprises to enterprises, institutions and individuals purchasing business jets (including helicopters) for their own use, and their uses include: helicopter ferrying passengers, helicopter medical rescue, and small passenger aircraft and other general aviation fields. After the national economy develops to a certain level, the general aviation market will become bigger and bigger. With the traction of general aviation market demand and the advancement of avionics technology, the deve...

AI Technical Summary

Problems solved by technology

[0007] 1) There is no general-purpose aircraft integrated avionics equipment and system shelf products;

[0008] 2) At present, the avionics system of domestic aircraft applicable to the field of general aviation is basically composed of discrete equipment, and the system's comprehensive ability is low; it lacks universal requirements, and is basically a dedicated avionics system suitable for a single model. system, there is no real universal platform system

[0009] 3) The system function does not have the ability of scalability, it cannot be expanded and tailored according to user needs, and it lacks good flexibility;

[0010] In short, the country has not really mastered the core technology of general-purpose aircraft integrated avionics systems, especially there is no real general-purpose core system oriented to actual system requirements, and based on this, general-purpose aircraft integrated avionics systems have been constructed
