【摘要】：物联网作为时下的新兴科技,随着对其研究和应用的广泛发展,备受世界各国科技人的青睐。物联网首先是将实际环境中需要监控、连接与互动的物体组建成一个无线传感网络,然后利用各种终端信息采集设备,实时地检测收集各种需要的信息,再与互联网结合构成一个巨大的线上与线下交互的通讯系统,进而实现物与物之间的网络信息交互和共享。引黄入晋工程是一项大型跨流域引水工程。该工程从黄河万家寨水库取水,分别向太原、朔州和大同3个能源基地供水,以解决严重的缺水危机。由于这样一个特定的工程应用背景,一般很难通过架设有线设备来完成对水域实时水情信息的监测和数据的传输,在这种情况下,无线通信的优势显得更加明显。而且在被测环境中,需要测量水位、水压等多项参数,这就为多个测量点组建网络提出了应用需求。多个参数的测量往往集中在一定的区域范围内,又为组建Zigbee无线传感器网络在通讯距离上提供了可行性。因此,我们结合Zigbee和GPRS的技术特性设计了一个基于Zigbee-GPRS的无线网络水情监测系统。本文根据无线传感器网络的组成原理、通信协议和对引黄入晋工程被测环境中水情监测需求的分析,设计了一个整体的硬件和软件方案,并且进行了实验验证和分析。该方案综合了Zigbee的自组织、短距离、低功耗特性和GPRS的远程传输优势,将各个水情检测设备通过CC2530芯片设计成网络终端采集节点,在一定范围内实现星型拓扑结构组网,再通过Zigbee协调器节点与GPRS模块实现与上位机软件的无线通讯,从而实现监测区域内的无线网络水情监测。软件方面,设计了基于Labview的上位机监测软件,可以在线实时地监测环境中的各个节点的参数,并通过曲线图表进行显示,同时将采集到的数据保存到数据库中,以便于查询和维护采集到的水情数据。整个设计以无线传感器网络为基础,实现了现代化、网络化的水情监测,具有一定的工程实际意义。经过试验分析和验证,此系统能够稳定运行,基本满足了远程水情监测的无线网络化和现代智能化需求。通过整个系统的设计,终端设备、互联网与人有效的连接到了整个网络中,实现了高质量的信息共享服务。通过对无线传感器网络节点部署模型的学习和分析,我们设计了一个基于邻居节点平均距离的无线传感器网络覆盖判别模型,此模型较传统的网络覆盖模型可以更好地节约无线传感器网络中工作节点的数量。
[Abstract]:Internet of things (IOT) as a new technology, with the extensive development of its research and application, is favored by the scientific and technological people all over the world. Objects connected to and interacted with each other form a wireless sensor network, and then use various terminal information acquisition devices to detect and collect all kinds of information needed in real time, and then combine with the Internet to form a huge online and offline communication system. Then realize the network information exchange and sharing between things and objects. The Yellow River diversion Project is a large cross-basin water diversion project. The project draws water from the Wanjiazhai Reservoir of the Yellow River and supplies water to three energy bases, Taiyuan, Shuozhou and Datong, respectively. In order to solve the serious water shortage crisis. Because of such a specific engineering application background, it is generally difficult to complete the monitoring of real-time water regime information and the transmission of data through the erection of wired equipment. In this case, The advantages of wireless communication are more obvious. Moreover, in the measured environment, many parameters, such as water level, water pressure and so on, need to be measured. Therefore, the measurement of multiple parameters is often concentrated in a certain area, which provides the feasibility of constructing Zigbee wireless sensor network in communication distance. Combining the technical characteristics of Zigbee and GPRS, we design a wireless network hydrologic monitoring system based on Zigbee-GPRS. According to the composing principle of wireless sensor network, the communication protocol and the analysis of the water condition monitoring requirement in the measured environment of the Yellow River diversion Project, a whole hardware and software scheme is designed in this paper. The scheme integrates the advantages of self-organization, short distance, low power consumption and remote transmission of GPRS, and designs each hydrologic detection device into a network terminal acquisition node through CC2530 chip. In a certain range of star topology network, and then through the Zigbee coordinator node and GPRS module to achieve wireless communication with the host computer software, so as to achieve the monitoring of wireless network hydrological monitoring in the region. Software, The monitoring software of upper computer based on Labview is designed, which can monitor the parameters of each node in the environment in real time on line, and display it by curve chart, at the same time, the collected data can be saved to the database. To facilitate the query and maintenance of collected hydrological data. The whole design is based on wireless sensor network and realizes the modern and networked monitoring of water regime. It has certain engineering practical significance. After experimental analysis and verification, the system can run stably. Through the design of the whole system, the terminal equipment, the Internet and the person are effectively connected to the whole network, and the high quality information sharing service is realized. By studying and analyzing the node deployment model of wireless sensor network, we design a wireless sensor network coverage discriminant model based on the average distance of neighbor nodes. Compared with the traditional network coverage model, this model can save the number of working nodes in wireless sensor networks.
