Embodiment Construction

[0027] figure 1 A schematic diagram of the connection relationship between a comprehensive modular avionics cabinet and an aircraft external system according to Embodiment 1 of the present invention is shown.

[0028] Such as figure 1 As shown, a comprehensive modular aviation cabinet, the cabinet includes:

[0029] Two built-in time-triggered Ethernet switches provide network connection between the cabinet and other aircraft systems outside the cabinet;

[0030] Among them, other aircraft systems outside the cabinet refer to other systems that do not reside in the cabinet.

[0031] Three general-purpose processing modules, respectively connected to each built-in time-triggered Ethernet switch, provide processing resources for resident applications of other systems of the aircraft, and are used to realize data interaction between resident applications and other systems of the aircraft outside the cabinet; among them, The resident application is determined according to the d...

Abstract

The embodiments of the invention disclose a comprehensive modularized avionics cabinet, a system and a flight apparatus and a data transmission method, and belong to the technical field of avionics. The cabinet includes: 2 built-in time triggering Ethernet switches which provide network connection to the cabinet and other systems of an airplane outside the cabinet; 3 general processing modules which are in separate connection to the built-in time triggering Ethernet switches, provide processing resources to hosted applications of an airplane system and are intended for implementing data interaction between the hosted system and other systems of the airplane outside the cabinet; 2 power control modules which are connected to the built-in time triggering Ethernet switches and the general processing modules and are intended for powering the built-in time triggering Ethernet switches and the general processing modules.

Description

technical field [0001] The invention relates to the technical field of avionics, in particular to a comprehensive modularized avionics cabinet, system, flight device and data transmission method. Background technique [0002] Integrated Modular Avionics System Architecture (Integrated Module Aviomics, IMA, modularized integrated avionics system) is a comprehensive avionics system architecture used by typical aircraft in service. Both the A380 and B787 aircraft avionics systems use the IMA architecture. The core processing system of the A380 aircraft is divided into four functional partitions: cockpit, cabin, energy and shared equipment. Different functional partitions use multiple IMAs to connect the systems with a unified AFDX network to jointly manage and execute the avionics tasks of the entire aircraft. , the core processing and input / output module used by the A380's IMA is called CPIOM. Each CPIOM module contains 1 central processing unit circuit board, 1 power supply ...
