摘要
2020年7月31日,中国北斗三号全球卫星导航系统全面开通服务,成为信息社会万物互联和万物智能的基础。本文结合中国北斗三号系统的服务类型与物联网应用北斗的主要模式,通过对物联网架构和关键技术的分析,提出了以北斗定位和时间基准数据为主要感知信息,以北斗短报文等特色服务为主要信息传输手段,融合互联网和人工智能技术的北斗物联网技术架构。总结分析了北斗各类服务在物联网相关领域的应用,提出了"物联网+北斗"的应用模式,以智慧城市、智能交通等典型应用为例,分析了北斗物联网技术的挑战,给出了初步发展建议,展示了中国北斗系统作为创新驱动发展的新动能。
China’s Beidou-3 global satellite navigation system,short for Beidou system(BDS),was fully operational on July 31,2020,which has become the basis of the interconnection and intelligence of all things in the information society.Based on the analysis of the architecture and key technologies of Internet of Things(IoT),the service types of BDS,and the main mode of BDS applications in IoT,this paper proposes a BDS-IoT technology architecture,which takes BDS’s positioning and timing as the main perception information,takes the short message and other characteristic services as the main information transmission means,and integrates Internet and artificial intelligence technology.Then,the typical application of BDS services in the IoT field is further analyzed,and the application mode of"IoT+BDS"is put forward.Finally,taking smart city,intelligent transportation and other applications as examples,the challenge of BDS is analyzed,the development advice is given,and the new driving force of BDS for innovation driven development is proved.
