Abstract

A comprehensive avionics system airborne equipment software on-line upgrading method adopts a comprehensive avionics system airborne equipment software on-line upgrading system to realize software on-line upgrading, the comprehensive avionics system airborne equipment software on-line upgrading system comprises a display control end, a loading end and a target end, and on the basis of ARINC615A data loading protocol rules, in an AFDX (Avionics Full Duplex Switched Ethernet) network of the display control end, on the basis of the ARINC615A data loading protocol rules, the on-line upgrading of the comprehensive avionics system airborne equipment software on-line upgrading system is realized. A loading end uploads data to a target end or downloads data from a target machine end, transmission and solidification of loadable data are achieved through AFDX bus network cross-linking, and therefore on-line upgrading of airborne electronic equipment software with an AFDX bus interface is completed. According to the airborne electronic equipment, software online upgrading can be achieved only according to an ARINC615A data loading protocol, operation is convenient and fast, the airborne electronic equipment does not need to be disassembled, and existing potential hazards are effectively eliminated.
