摘要
针对在天基多域信息系统中,各类电子设备不断增加和推陈出新,进而使得天基多域信息系统中数据量更大、数据类型更多、数据复杂性更高的特点,对数据分发服务(DDS)技术进行研究,提出了一种应用在天基多域信息系统网关上的基于国产操作系统的数据分发服务实现技术;基于PowerPC P1022平台,完成对国产化自主可控嵌入式操作系统风云翼辉(AIC-OS)嵌入式操作系统的移植适配,同时联合VxWorks、Windows平台,搭建起一套基于DDS技术的天基多域信息分发系统;之后针对天地网络一体化通信的背景需求,分别对该系统的联通性、可靠性、在线感知能力、通信时延等多方面能力进行实验测试;实验结果表明,可以有效实现天基多域信息系统的互联互通,实现数据在不同用户间的发布和订阅。
In the space-based multi domain information system,various electronic devices are increasing and bringing forth the new through the old,which makes that the space-based multi domain information system is characterized by larger data volume,more data types and higher data complexity.The Data Distribution Service(DDS)technology is studied,and a data distribution service implementation technology based on the domestic operating system applied to the gateway of the space-based multi domain information system is proposed;Based on the PowerPC P1022 platform,the transplantation and adaptation in the domestic autonomous and controllable embedded operating system(FengYunYiHui AIC-OS)are completed.Meanwhile,a space-based multi domain information distribution system based on DDS technology is built through combing the AIC-OS,VxWorks and Windows platforms.After that,according to the background demand on the integrated communication of the heaven and earth network,the connectivity,reliability,online sensing ability,communication delay and other capabilities of the system are tested respectively.The experimental results show that the system can effectively realize the interconnection of the space-based multi domain information system,and realize the data publication and subscription among different users.
