Embodiment Construction

[0032] Concrete steps of the present invention are as follows:

[0033] 1) if figure 1 As shown, design the ICD configuration file:

[0034] In the ICD configuration file, there are four elements.

[0035] ●ICD element: This element is the root element. Multiple BLOCK elements can be included in one ICD element, and each BLOCK element is unique.

[0036] ●BLOCK element: In the attributes of this element, name indicates the block name, wordNum indicates the number of signals in the block message, flag indicates the unique flag of the block, belongTO indicates the name of the ICD to which the block belongs, and description indicates the name of the block message note. Multiple SIGNALs can be included in each BLOCK, and the relationship between SIGNAL and BLOCK is a many-to-many relationship.

[0037] ●SIGNAL element: In the attribute of this element, name indicates the font size of the signal, fieldCount indicates the number of fields in the signal, wordDesignation indicates...

Abstract

The invention discloses a universal airborne bus interface control document analyzing and packaging method. The method comprises the steps of designing an ICD configuration file; designing a universal bus ICD analyzer model; designing a bus ICD analyzer configuration file; designing a bus ICD analyzer factory class; creating an A429 bus ICD analyzer; and abstracting ICDs of various different airborne buses into a universal airborne bus ICD model to perform packaging and analyzing. The method has the beneficial effects that the problem of automatic adaptation of interfaces for analyzing and packaging the ICDs of the various airborne buses in codes of an airborne application is solved; and the ICDs of the various different airborne buses are abstracted into the universal airborne bus ICD model, so that the demand of performing communication by using different types of buses on a bottom layer through the airborne application is met.

Description

technical field [0001] The invention belongs to the technical field of aircraft avionics systems, and relates to a method for parsing and packaging a general airborne bus interface control document ICD (Interface Control Document). Specifically, by researching and analyzing ICDs of different buses, extracting common features, and then designing a general airborne bus interface control document (ICD) model, the versatility of ICDs for different buses in parsing and packaging is completed. question. Therefore, a common ICD parsing and packaging method is provided for complex systems that use different buses for communication. It provides a good foundation for building a general airborne bus test and monitoring system. Background technique [0002] With the continuous development of avionics systems, the types and quantities of communication buses are constantly increasing. Different types of buses have certain differences in the definition of the ICD format, so that the cod...
