【摘要】：集计算机技术、无线网络技术和智能传感等技术于一身的新型网络“物联网”正悄然改变着我们的生活,“物联网”是继计算机和互联网之后,世界信息产业的第三次重大变革。面向物联网的市场需求,本文提出一种基于多网融合技术的远程传感监控及控制系统。本文采用的多网融合方案,研究的出发点是为数据采集和处理提供完整稳定的传输通道,使得信息能够通过传感器从源网络安全高效地传输到目的网络,研究的内容是利用多种网络的优势,搭建合理的信息远程传感监控及控制平台,有效地提高了信息传输的可靠性。本文首先对多种无线通信技术进行分析研究,在构建被监控的传感器网络中,选取具有多种优势的ZigBee网络,并尝试对几种常用传感器与通用ZigBee模块进行了集成,很好地提高了传感器网络的效能,使得传感网络进一步集约化;在对传感信息进行远程传输中,选用了目前技术成熟的公共3G网络,实现数据的远程传输,极大地拉长了传感信息的可传距离。尔后提出一种基于多网融合技术的远程传感监控及控制系统,在满足通信系统的各项要求指标的基础上,采用多级控制、统一管理,实现对传感器终端的远程监测和管理。系统由传感器节点、ZigBee网络、ZigBee/3G网关、公共通信网络(3G、GPS等)、电源系统、服务器和客户端等组成。系统首先从服务器发送命令开始,命令到达传感器终端节点后开始采集信息,数据通过ZigBee终端节点、路由器和协调器传输至ZigBee/3G网关,经过网关的ARM11处理器协议转换以及数据预处理后再传输至3G网络,通过3G网络传输到服务器,从而完成系统的一个工作周期。基于此研究需求,本文着重研究ZigBee传感器网络和网关设计。利用ARM平台将多个ZigBee子网连接起来,形成一个较大的ZigBee网络,扩大了网络的容量和覆盖范围。本系统对多种网络技术(ZigBee、3G和GPS等)融合运用于远程监控领域做了初步的探索与尝试,提供了一种较为理想的“物联网”技术路线。系统可移植性强,稍加修改可用于环境的监测、自动化制造、智能家居等多种涉及传感器采集数据和自动控制的领域。
[Abstract]:The Internet of things, a new network that integrates computer technology, wireless network technology and intelligent sensing technology, is quietly changing our lives. The Internet of things is after computers and the Internet. This paper presents a remote sensor monitoring and control system based on multi-network fusion technology. The starting point of the research is to provide a complete and stable transmission channel for data acquisition and processing, so that information can be transferred safely and efficiently from the source network to the destination network through the sensor. The reliability of information transmission is improved effectively by setting up a reasonable information remote sensor monitoring and control platform. Firstly, this paper analyzes and studies various wireless communication technologies, and constructs the monitored sensor network. The ZigBee network with many advantages is selected, and several commonly used sensors are integrated with the general ZigBee module, which improves the efficiency of the sensor network and makes the sensor network more intensive. In the remote transmission of sensing information, the public 3G network with mature technology is selected to realize the remote transmission of data. After that, a remote sensing monitoring and control system based on multi-network fusion technology is proposed. On the basis of meeting the requirements of the communication system, multilevel control and unified management are adopted. The system consists of the sensor node ZigBee network ZigBee network ZigBeer 3G gateway, public communication network such as GPS, power supply system, server and client. After the command arrives at the sensor terminal node, it starts to collect information. The data is transmitted to the ZigBee/3G gateway through the ZigBee terminal node, the router and the coordinator. After the ARM11 processor protocol conversion and data preprocessing of the gateway, the data is transmitted to the 3G network. This paper focuses on the design of ZigBee sensor network and gateway, and connects several ZigBee subnets with ARM platform. A large ZigBee network has been formed, which has expanded the capacity and coverage of the network. This system has made a preliminary exploration and attempt on the integration of various network technologies, such as 3G and GPS, in the field of remote monitoring and control. An ideal "Internet of things" technology route is provided. The system has strong portability and can be used for environment monitoring, automatic manufacturing, intelligent home and other fields involving sensor data collection and automatic control.
