物联网是互联网发展到今天的高级产物,目前还没有一个权威的定义。从技术的角度说,任何一个互联互通的网络都可以实现,比如电信、移动、联通、广电等,也可以是一个独立局域网。对于普通用户来说,物联网重要的不是网络本身,而是基于这些网络的应用服务。能从这些网络中得到哪些服务,这才是与我们的工作生活相关的。简单地说,服务才应该是物联网的关注点。本文介绍了物联网的概念,并从工业、农业、教育和生活等方面详细介绍了物联网的应用,并分析了物联网在中国的发展前景。 Internet of things is the advanced product of today’s Internet development, there is no definitive definition yet. From a technical point of view, any interoperable network can be achieved, such as telecommunications, mobile, China Unicom, radio and television, but also can be an independent LAN. For ordinary users, the Internet of things is not the network itself, but rather based on the application services of these networks. Which of these services are available from these networks is what is relevant to our work life. In short, services should be the focus of the Internet of things. This article introduces the concept of IoT and details the application of IoT in industry, agriculture, education and life, and analyzes the development prospect of IoT in China.
