摘要
为适应日益发展的综合化航空电子系统及机载网络技术,航电系统维护中尤其是软件升级需要一套标准的数据及文件传输规范来保证加载的安全性和高效性。选用ARINC 615A数据加载协议,在深入分析其传输操作、传输文件以及传输协议的基础上,采用FC高速网络,设计适合ARINC 653和非ARINC 653操作系统的航电数据加载服务系统,并引入状态监控、CRC校验和短加载机制,实现数据加载的正确、稳定、可靠。
To adapt to the increasing development of integrated model avionics system and airborne network technology, avionics system maintenance especially software update needs a standard transmission specification to ensure data load safety and high efficiency. An ARINC 615A Data Load Service System design is presented, using FC high speed transmission network, ARINC 653 and non- ARINC 653 Operating System based on studying AR1NC 615A protocol deeply. Furthermore, application of status monitor, cyclic redundancy code, and short load excellently enhances the correctness, stability and reliability of data load.
