从物联网的基本概念和相关技术出发,追踪当前世界低轨通信星座系统和我国构建天地一体化信息网络的发展趋势,提出了空间物联网的基本概念。空间物联网与传统卫星物联网不同,不仅是利用卫星中继解决远程的机器通信问题,而是在天地一体化信息网络架构下的一种泛在物联网体系,是地面物联网在全球立体空间层面的拓展,是多种信息技术融合而成的综合性应用服务平台。总结了海量数据业务特征下的空间物联网面临的主要挑战,包括系统负载过大、数据损毁丢失、链路频繁中断、能耗开销过高等数据存储与传输问题。进而提出了建立面向空间物联网应用服务的星地一体化分布式存储与传输系统的设计思路,介绍了关键技术,实现了海量信息业务的安全保障和跨域互联。最后,对未来空间物联网的研究热点方向提出了展望和思考。
Based on the concepts and related techniques of Internet of things (IoT)
tracking the development tendency of the satellite IoT and LEO constellation communication system abroad
and the deployment of the integrated satellite-terrestrial information network in China
the concept of space Internet of things (Space IoT) with its framework and main characteristics was proposed.Space IoT has the different concept compared to the traditional IoT
not just using the relay satellite to implement remote machine-to-machine communication.Space IoT is a ubiquitous IoT system under the integrated satellite-terrestrial information network architecture
and an expansion of the terrestrial IoT in the global three-dimensional world
and a service and application platform of multiple information technologies.With the recently era of big data
the space IoT has to face some data storage and transmission problems
such as excessive system load
data loss
frequent link interruption
high energy consumption
etc.Establishing a space-oriented IoT integrated distributed storage and transmission system was to meet the requirements of security guarantee and cross-domain interconnection with massive information businesses.Development status of related technologies were illustrated.At last
the prospect and thought of the future research of space Internet of things were presented.
