物联网也称传感网,是一个利用传感网络和信息技术将各种物体与网络相连,以获取所需物体相关信息并进行业务应用处理的网络。物联网在世界范围内的定义有各种表述,一般认为:物联网是指按照约定的通信协议,通过感知器件或终端设备把物品联入网络,进行信息通信、交换和处理,以实现智能化应用和管理的一种网络。物联网的体系架构物联网体系架构可划分为感知层、传输层、处理层和应用层。感知层主要组成包括二维码标签和识读器、
Internet of Things is also called sensor network, which is a network that uses sensor networks and information technologies to connect various objects to the network in order to obtain information about the required objects and process business applications. The definition of the Internet of Things (IoT) has various expressions all over the world. It is generally believed that the Internet of Things (IoT) refers to that the IoT is to intelligentize information communication, exchange and processing according to the agreed communication protocol by connecting articles to the network through a perceptual device or terminal device A network of applications and management. IoT architecture IoT architecture can be divided into the perception layer, transport layer, processing layer and application layer. The main components of the perception layer include two-dimensional code tags and readers,
