RapidIO在分布式机载传感器系统中的应用

针对分布式机载传感器对设备内外一体化的大规模网络传输需求，提出了一种结合大数据平台设计思想的RapidIO网络架构。通过多星网络集群、RapidIO节点虚拟、网络资源抽象与网络切片管理等设计，将以往RapidIO在设备内部的简单应用扩展为多个设备互联的大规模分布式复杂应用。设计的网络具备可靠性高、支持多种计算模型、快速伸缩等特点。该网络已经在某分布式机载传感器样件中完成了部署、实验室验证、环境试验验证、交付验收以及性能评估，初步验证了RapidIO技术在分布式机载传感器系统工程化的可行性，为后续不同飞机平台型号工程使用分布式RapidIO技术奠定了基础。

Application of RapidIO interconnection technique in distributed airborne sensor system

According to the large-scale network transmission requirements of distributed airborne sensors for the integration of internal and external equipment,a RapidIO network architecture combined with the design idea of big data platform is proposed.Through the design of multi-satellite network cluster,RapidIO node virtualization,network resource abstraction and network slice management,the previous simple application of RapidIO in the device is extended to a large-scale distributed complex application interconnected by multiple devices.The design has the features of high reliability,supporting multiple computing models,fast scaling,etc.This network has been deployed in a distributed airborne sensor sample and laboratory validation,environmental testing,delivery acceptance,and performance evaluation have been completed.It is preliminarily proved that RapidIO technology is feasible for the engineering of distributed airborne sensor systems and lays a foundation for the use of distributed RapidIO technology in the future for different types of airplane platforms.
