摘要
物联网、物联网系统与物联网事件是物联网相关的三个概念层次。物联网应用体现在物联网系统中。物联网系统有三个层次,即应用层、网络层、物理层。应用层反映物联网系统的功能、服务要求;网络层是物联网系统实现的网络基础;物理层则是与物理对象连接、交互的底层环境。物联网系统的基本特点是"三化两性",即无人化、自动化、智慧化、实时性与无限性。
IOT, IOT system and IOT event are the three levels of the concept of the Internet of Things. IOT application is realized in IOT systems. IOT has three layers： application layer, network layer and physical layer. Application layer shows the function and serv- ice requirement of IOT system; network layer is the network basis for IOT implementation; physical layer is the underlying environment for the interconnection and interaction of physical objects. IOT system basic characteristics include unattended operation, automation, intelligence, real-time characteristic and infinity.
