摘要
当前物联网的定义、内在原理、体系结构和系统模型等方面还存在许多值得探讨的问题,为此,通过解析物联网的基本概念和特征,提出了物联网体系架构的感知层、网络层及应用层的三层架构,归纳了物联网涉及的射频识别、传感器、网络通信和云计算等关键技术,讨论了物联网在对象识别,跟踪及控制方面的具体应用。
At present there are a lot of issues with Internet of Things to be worth being discussed, including its definition, internal principles, system architecture and models. Therefore, through analyzing the basic concepts and features of the Internet of Things, we put forward its three-layer architecture including sensing layer, internet layer and application layer, sum up its key technologies such as RFID, sensor, network communications and cloud computing, discuss its specific application in object recognition, tracking and control.
