Design and implementation of on-line update method of airborne equipment software

Abstract： In this paper, a remote online software update method based on 1553B bus and Serial RapidIO（SRIO） high-speed serial port is proposed to solve the problems of large number of internal software, large scale, long update time, scattered to multiple modules, difficult disassembly and assembly of airborne equipment under the loading condition. The system composition and working principle are described, and the remote online update method and implementation process are given. This method effectively solves the online update requirements and software maintenance of complex stand-alone software with high reliability and high throughput under the condition of full ammunition. It has the advantages of flexibility, reliability and high data rate in practical application.
