摘　　要：随着通信网络和分布式计算技术的发展,机载信息系统将更加信息化、综合化、智能化。然而,传统的机载信息系统有效实现了各个模块之间数据的交互,但是在航电数据的实时性、可靠性方面还有待改进完善。数据分发服务中间件技术采用以数据为中心的订阅/发布机制来提高系统的实时性、吞吐量,降低延迟,是一种良好的解决思路。文章以天脉1操作系统和高性能处理器Power PC7447为平台,采用DDS中使用的面向对象技术和设计模式,设计并实现分布式数据分发工具,包括DDS、TFTP和RPC组件,支持面向分布式服务的架构,可提高机载信息系统的实时性、可靠性、安全性、扩展性。With the development of communication network and distributed computing technology,infbnnation system will be more infbrmationized,integrated and intelligent.However,although the traditional airborne information system can effectively realize the data interaction between various modules,the real-time and reliability of avionics data need to be improved.Data Distribution Service middleware technology adopts the Data-Centric Publish-Subscribe mechanism to improve the real-time performance,throughput and reduce the latency of the system,which is a good solution.Based on the platform of the ACoreOSl operating system and high-performance processor PowerPC 7447,and adopting object-oriented technology and design mode used in DDS,this paper designs and implements distributed data distribution tool,including DDS,TFTP and RPC components,which supports a distributed service-oriented architecture and can improve the real-time,reliability,security and scalability of the airborne mfbnnation system.
