本发明涉及无线传感器网络及移动终端技术， 具体涉及无线传感器网 络、 移动终端及其互联方法和***。 背景技术  The present invention relates to a wireless sensor network and a mobile terminal technology, and in particular to a wireless sensor network, a mobile terminal, and a method and system therefor. Background technique
物联网的概念是在 1999年提出的。在中国，物联网又被称之为传感网。 2005年 11月 17日， 在突尼斯举行的信息社会世界峰会 ( WSIS )上， 国际 电信联盟（ITU )发布了 《ITU互联网报告 2005: 物联网》， 正式提出了"物 联网"的概念。 报告指出， 无所不在的"物联网"通信时代即将来临， 世界上 所有的物体从轮胎到牙刷、 从房屋到纸巾都可以通过因特网主动进行交换。 射频识别技术（RFID )、 传感器技术、 纳米技术、 智能嵌入技术将到更加广 泛的应用。  The concept of the Internet of Things was introduced in 1999. In China, the Internet of Things is also known as the sensor network. On November 17, 2005, at the World Summit on the Information Society (WSIS) in Tunis, the International Telecommunication Union (ITU) released the ITU Internet Report 2005: Internet of Things, which officially proposed the concept of “Internet of Things”. The report points out that the ubiquitous "Internet of Things" communication era is coming, and all the world's objects can be actively exchanged via the Internet from tires to toothbrushes, from houses to paper towels. Radio Frequency Identification (RFID), sensor technology, nanotechnology, and intelligent embedded technology will be used in a wider range of applications.
根据 ITU的描述， 在物联网时代， 通过在各种各样的日常用品上嵌入 一种短距离的移动收发器， 人类在信息与通信世界里将获得一个新的沟通 维度， 从任何时间任何地点的人与人之间的沟通连接扩展到人与物和物与 物之间的沟通连接。  According to the ITU, in the Internet of Things era, by embedding a short-range mobile transceiver on a wide range of everyday products, humans will gain a new dimension of communication in the world of information and communication, from any time, anywhere. The communication connection between people extends to the communication between people and things and things.
物联网产业链可以细分为标识、 感知、 处理和信息传送四个环节， 每 个环节的关键技术分别为 RFID、 传感器、 智能芯片和电信运营商的无线传 输网络。 物联网把新一代 IT技术充分运用在各行各业之中， 具体地说， 就 是把感应器嵌入和装备到电网、 铁路、 桥梁、 隧道、 公路、 建筑、 供水系 统、 大坝、 油气管道等各种物体中， 然后将 "物联网"与现有的互联网整合起 来， 实现人类社会与物理***的整合， 在这个整合的网络当中， 存在能力 超级强大的中心计算机群， 能够对整合网络内的人员、 机器、 设备和基础 设施实施实时的管理和控制， 在此基础上， 人类可以以更加精细和动态的 方式管理生产和生活， 达到"智慧"状态，提高资源利用率和生产力水平， 改 善人与自然间的关系。 The Internet of Things industry chain can be subdivided into four parts: identification, sensing, processing and information transmission. The key technologies in each link are RFID, sensors, smart chips and wireless transmission networks of telecom operators. The Internet of Things leverages the next generation of IT technology in a wide range of industries, specifically embedding and equipping sensors into power grids, railways, bridges, tunnels, roads, buildings, water systems, dams, oil and gas pipelines, etc. Among the objects, the "Internet of Things" is then integrated with the existing Internet to realize the integration of human society and physical systems. In this integrated network, there is a super-powerful central computer group capable of integrating people within the network. , machines, equipment and foundations The facility implements real-time management and control. On this basis, humans can manage production and life in a more sophisticated and dynamic way, achieve a "smart" state, improve resource utilization and productivity levels, and improve the relationship between people and nature.
由此可见， 物联网的价值不仅仅是一个可传感的网络， 而且各个行业 参与进来进行应用， 不同行业， 会有不同的应用， 也会有各自不同的要求， 这些必须根据行业的特点， 进行深入的研究和有价值的开发。 这些应用开 发需要一个物联网的体系基本形成， 需要一些应用形成示范， 更多的传统 行业感受到物联网的价值， 这样才能有更多企业看清楚物联网的意义， 看 清楚物联网有可能带来的商业价值， 也会把自己的应用与业务与物联网结 合起来。  It can be seen that the value of the Internet of Things is not just a sensible network, but various industries are involved in the application. Different industries have different applications and different requirements. These must be based on the characteristics of the industry. Conduct in-depth research and valuable development. These application developments require an IoT system to be basically formed, and some applications need to be modeled. More traditional industries feel the value of the Internet of Things, so that more companies can see the meaning of the Internet of Things and see that the Internet of Things may bring The business value that comes with it will also combine its own applications with the business and the Internet of Things.
