未来物联网的发展优势

未来物联网的发展优势,第1张

随着物联网行业的发展,人类建造智能家庭、办公室、街道和城市的梦想正在实现。
物联网的概念最先由英国科学家KevinAshton提出,就是指一种和现实生活紧密相连的网络系统。物联网可以提供一个由内部交流设备构成的全球网络服务,它结合无所不在的交流,海量的计算和遍及的情报信息。

当前,物联网技术中“物”特指日常生活用品,比如:各种各样家用电器、家具、衣服、交通工具,还有其他各种网络可以识别、定位、控制的物品。

优势

尽管现在有很多将实体物品联网的有趣应用,但物联网的发展还处于初级阶段,需进一步挖掘出其潜在巨大价值才能被广大用户接受和广泛使用,所以物联网专业正处于蓄势待发的阶段,前景无限广阔。

这项技术的优点包括:优化的体验;商业活动自动化的可见性和可测量性;通过实时高分辨率的信息捕捉可提供性价比更高的服务;实现对产品实时性能信息的分析;通过提高运行效率、准确性、灵活性和自动化来创新已存在的商业流程。

发展趋势

物联网技术的部署趋势包括:

感应器尺寸的减小:微软电系统和纳电子学正在致力于制作尺寸更小的节能传感器,以应用在比较小的物体或有生命的系统之中。思科系统公司、爱特梅尔半导体公司、瑞典计算机研究院和其他技术供应商还有IPSO,联合推出IPv6,这是世界最小的开放资源之一,能够兼容各个应用,不管能量和记忆多么有限,一旦有了网络协议地址,就可以推广物联网应用。

将移动电话作为数据采集设备:这一趋势是指移动手机数据采集功能的扩展。支持网络连接的手机,作为一种已经普及的通讯工具,在推动数据采集的广泛应用和接收方面有很大优势,如同很多移动设备都能用摄像机来识别2D条码。

阻碍

物联网的发展在很大程度上依赖于机器对机器(M2M)的对接、电子通讯协议、嵌入系统,无线通讯、射频识别(RFID)、感应器等技术的进步,并且每个加入物联网的物品都要有自己的识别身份。管理一个集命名、地址标注和发现为一体的全球网络体系是一件非常艰巨的工作。

射频识别也是一种感应器。市场上感应器多种多样,功能也不尽相同,这些感应器构成网络建设的主要成本。另外一个阻碍就是在技术部署过程中需要有坚固的智能设备,以防御任何极端环境的破坏。

信用、隐私和安全问题对物联网也是至关重要,该项技术的发展还要解决数据所有权和管理方式的问题。
