【摘要】 物联网是互联网技术、物物之间的网络化的代名词,以及信息技术的综合应用,并且引发了信息产业的第三次浪潮,被世界各强国列为重点开发的领域之一。显然,它的出现会影响相关国家安全、政治、经济发展、社会安全等多个领域,并且会在未来对人们的工作和生活带来巨大的影响。物联网会成为新一代信息科技的重要组成部分。它的英文名为“The internet of things"。顾名思义,“物物相连接的网络”。它包括两层意思：第一,物联网的主要基础仍以互联网为导向,并且是以网络为基础的一种延伸与扩展；第二,物联网在对延伸和扩展的对象之间进行信息交换和网络通讯。因此可总结出,物联网的定义是：把任何实物与互联网络相连接,包括各种传感设备等进行信息交换和通信,实现了信息的共享,网络间通信,智能目标的识别定位和跟踪,及监控管理。本课题是通过物联网技术的应用和理念,搭建基于Arduino-Intel Galileo开发板的平台,在Ubuntu环境下设计出机器运行噪音的远程监测系统。通过对噪声信号的A/D转换和声学换算,完成了对不同传声器数据的采集。利用系统的分析模块对数据的实时、频域上的数据进行分析处理,实现了对不同设备在不同条件下运行时所产生噪声的监测和预警。基于IOT (Internet Of Things)物联网音频信号采集设备所收集到的信息(高灵敏传感器或麦克风),进行分析处理,并通过Wi-Fi网络发送预处理的数据到数据中心。由数据中心进一步分析处理数据,然后显示出监测机器的运行状态。同时通过建立的网络服务器,用户可以在他们的移动终端上进行远程监测机器的运行状态。通过可视化模块设计出一款明确的、生动的用户显示界面。更多还原

【Abstract】 Internet of things is the Internet technology, the network of the Internet of things and the comprehensive application of information technology which led to the third wave of the information industry. It is areas of the world as one of the development. Obviously, it will affect the national security, political, economic development, social security and other aspects. It will have a great impact on people’s work and life in the future.Internet of things will become an important part of the new generation of information technology. As the name suggests "The Internet of things’’. It includes two meanings:first, the basis of things connect to the Internet for the mainstream and in the network based on a kind of extension and expansion; second, it is between the extension and expansion of any object were the exchange of information and network communications. It can be summed up; definition of networking is to connect any kind of Internet, a variety of sensing equipment for information exchanges and communication, information sharing, network communication, intelligent target recognition and location tracking, monitoring and management.This topic is through the use a platform of Internet technology and the idea of building an Arduino-Intel based Galileo development board, a machine running noise design of remote monitoring system in Ubuntu environment. The A/D conversion to the noise signal and acoustic conversion, completed the calibration of different microphones. The data in real time and frequency domain processing are using the analysis module of the system, the realization of monitoring and early warning of different equipment running under different conditions generated noise.Based on IOT (Internet Of Things) networking audio signal acquisition device to collect information (high sensitive sensor or microphone), analysis and processing functions, and through the Wi-Fi network send the preprocessed data to the data center. The data center on further processing of the data, and then monitoring the operation state of the machine. At the same time, the establishment of a network server, users can remotely monitor the running state on their machine in the mobile terminal. The design of a visual user interface is provided with the user interface display clear and vivid through visualization module.更多还原
