什么是“物联网”?

吴丽华 a4d116c0-5a17-1037-9663-91eec91f24f4 wlihua1@kinlong.cn | ‎ | 58 Views
物联网( IoT ,Internet of things )即“万物相连的互联网”,是互联网基础上的延伸和扩展的网络,将各种信息传感设备与互联网结合起来而形成的一个巨大网络,实现在任何时间、任何地点,人、机、物的互联互通 。
物联网是新一代信息技术的重要组成部分,IT行业又叫:泛互联,意指物物相连,万物万联。由此,“物联网就是物物相连的互联网”。这有两层意思:第一,物联网的核心和基础仍然是互联网,是在互联网基础上的延伸和扩展的网络;第二,其用户端延伸和扩展到了任何物品与物品之间,进行信息交换和通信。因此,物联网的定义是通过射频识别、红外感应器、全球定位系统、激光扫描器等信息传感设备,按约定的协议,把任何物品与互联网相连接,进行信息交换和通信,以实现对物品的智能化识别、定位、跟踪、监控和管理的一种网络。
