摘要
物联网是一个复杂的系统,如果不从系统角度研究物联网,则难以理解和把握物联网的内在特征和核心技术。从公共物联网角度分析了作为社会基础设施的物联网特征;从虚拟网络世界与现实物理世界融合角度提出了一个物联网的概念模型,讨论了由信息材料、网络化物理系统以及物理化网络系统构成的物联网核心技术;从物品、网络、应用三个维度提出了一个物联网体系结构,探讨物联网由信息物品、自主网络和智能应用组合而成的物联网内在特征;并且建议长期的物联网项目应该侧重于物联网基础设施类系统和技术的研究和开发。
The Internet of Things （lOT） is a complex system. If there is no intensive study from the sys- tem point of view, it will be hard to understand and master the intrinsic features and key technologies of IOT. The infrastructure features of IOT are analyzed in the view of publie IOT. A concept model of IOT is proposed in the view of converging Cyber world and physical world,and it discusses the key technologies of IOT which consists of information materials, cyber-physical systems and physical-cyber systems. The architecture of IOT is proposed in the three dimensions of things, networks, and applications, and the internal features of IOT are explored which is composed of information things, autonomous networks and intelli- gent applications. It is suggested that IOT projects in the long term should focus on the research and development of the infrastructure systems and technologies of IOT.
