Example Embodiment

[0017] In order to better understand the present invention, the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0018] like figure 1 As shown, a general IO processing system for an airborne avionics system includes a configuration generation tool module 103 and a general IO processing engine module 104. The configuration generation tool module automatically realizes the association mapping and conversion between the ICD data source 101 and the application data set 102 The configuration file is generated, and the general IO processing engine module 104 realizes the analysis of the configuration file, which realizes the complete decoupling of the avionics system ICD and the specific avionics application functions.

[0019] like figure 2 As shown, the ICD data source 101 defines various attributes of input / output messages of various bus types, including message name, message type, message protocol type, message up...

Abstract

The invention discloses a universal IO processing system for an airborne avionic system. The universal IO processing system comprises a configuration generation tool module and a universal IO processing engine module. The configuration generation tool module is used for acquiring input/output parameters of applications and signal sources corresponding to the applications from an application data set, extracting signals corresponding to each signal source from an ICD (interface control document) data source according to associated data, searching messages corresponding to the signals from the ICD data source, finding corresponding communication interfaces according to the messages, and thereby extracting out all configuration information to generate configuration files. The universal IO processing engine module is used for establishing communication interfaces according to the configuration files to realize communication with the outside and performing related operations according to various attribute values in the configuration files. The universal IO processing system has advantages that portability of avionic application functions is effectively improved, development efficiency of the avionic application functions in processing of large-scale high-complexity ICD data is remarkably improved, and development cost is sharply reduced.

Description

technical field [0001] The invention relates to the design technology in the field of computer software architecture, in particular to a method for processing general IOs of an airborne avionics system used in the software architecture technology. Background technique [0002] With the rapid development of avionics technology, the airborne avionics system has experienced three stages: discrete avionics, combined avionics and integrated avionics. In particular, the integrated avionics system has the characteristics of a high degree of resource sharing, a strong degree of data fusion, and intensive software functions. These characteristics of the avionics system lead to the extremely complicated interface ICD (Interface Control Document, Interface Control Document) between devices, especially in the face of a large-scale aircraft avionics system with highly integrated functions, the traditional IO method of directly processing the device interface ICD by the application It ha...
