【摘要】：旅游业作为我国国民经济的支柱型产业,其发展不仅能够有效助推区域经济的发展,而且旅游景区信息化水平的提升还能促进旅游景区现代化的发展,进而加快城市向现代化迈进的步伐。因此,拉萨市发布了2016年至2020年旅游产业发展目标,明确提出将投资1000亿元以建立智慧旅游体系及推进旅游区域的物联网建设等。物联网技术通常指通过射频识别(RFID)、红外感应器、全球定位系统、激光扫描器等信息传感设备,按约定的协议,将任何物品与互联网相连接,进行信息交换和通讯,以实现智能化识别、定位、追踪、监控和管理的一种网络技术,而ZigBee技术是物联网技术的支撑技术之一。相对于其他无线定位技术,ZigBee技术能够提供具有低功率、小范围、低速率、低价格和网络容量大等优点的网络,可以更好地提升景区的服务质量。本文在研究了ZigBee网络的拓扑结构和路由算法的基础上,提出了基于ZigBee网络的拉萨旅游景区内景点定位系统的研究。针对不同的研究内容,本文采用了文献分析、模拟仿真和实物系统搭建等三种研究方法。其中,文献分析法主要针对ZigBee技术及Zig Bee网络性能优化的相关研究等理论问题;模拟仿真法主要针对ZigBee网络规模对网络性能影响的模拟仿真问题;实物搭建法则主要用于实现拉萨旅游景区内景点定位系统。相应的本文有以下三项研究成果。第一,通过分析文献总结得出了ZigBee网络性能优化的相关研究包括ZigBee网络拓扑优化、ZigBee路由算法优化及其他协议层参数优化(如MAC层信标模式下的超帧参数)等三个层面;同时还得出了Zig Bee网络性能与网络规模的关系研究只限于理论研究和小规模网络对网络性能的影响研究等结论。第二,在文献分析的基础上,本文利用OPNET仿真软件提供的网络模型设计仿真实验,收集整理了负载、吞吐量、时延等指标数据,并通过分析比对指出实验环境下的路由器设备和终端设备数量分别控制在29—33个和63—84个范围内时,可以实现较好的ZigBee网络性能。第三,首先研究了基于ZigBee技术的智慧景区体系结构设计框架,然后以体系结构为指导研究了基于ZigBee技术景点定位系统中的软硬件详细设计,最后在片上系统解决方案CC2430/CC2431无线ZigBee模块、JLX12864G-1016显示模块及DS18B20温度传感器模块等搭建了硬件平台的基础上,设计实现了景点定位、数据采集传输、数据显示及游客位置信息的后台监测等四种软件功能的定位系统。
[Abstract]:As the pillar industry of our national economy, tourism development can not only effectively promote the development of regional economy, but also promote the development of tourism area modernization. And speed up the pace of modernization of the city. Therefore, Lhasa has released the tourism industry development target from 2016 to 2020, and has made it clear that it will invest 100 billion yuan to establish intelligent tourism system and promote the construction of Internet of things in tourism area. Internet of things technology usually refers to information sensing equipment such as RFID, infrared sensors, global positioning systems, laser scanners, and so on. According to an agreed protocol, any object is connected to the Internet for information exchange and communication. In order to achieve intelligent identification, positioning, tracking, monitoring and management of a network technology, and ZigBee technology is one of the supporting technologies of the Internet of things. Compared with other wireless positioning technology, ZigBee technology can provide low power, small range, low speed, low price and large network capacity, which can better improve the quality of service of scenic spots. On the basis of studying the topology and routing algorithm of ZigBee network, this paper puts forward the research of Lhasa scenic spot location system based on ZigBee network. According to different research contents, this paper adopts three research methods: literature analysis, simulation and physical system construction. Among them, the literature analysis method mainly focuses on ZigBee technology and Zig Bee network performance optimization related theoretical issues, simulation method is mainly aimed at the impact of ZigBee network size on network performance simulation. The object-building principle is mainly used to realize the Lhasa scenic spot location system. The corresponding article has the following three research results. First, through the analysis literature summary, the related research of ZigBee network performance optimization including ZigBee network topology optimization ZigBee routing algorithm optimization and other protocol layer parameters optimization (such as MAC layer beacon mode superframe parameters) three layers; At the same time, it is concluded that the relationship between Zig Bee network performance and network scale is limited to theoretical research and the influence of small-scale network on network performance. Secondly, on the basis of literature analysis, this paper uses the network model design simulation experiment provided by OPNET simulation software to collect and sort out the data of load, throughput, delay and so on. Through analysis and comparison, it is pointed out that when the number of router equipment and terminal equipment are controlled in the range of 29-33 and 63-84, respectively, the better performance of ZigBee network can be achieved. Thirdly, the architecture design framework of Smart Scenic spot based on ZigBee technology is studied firstly, and then the detailed design of software and hardware in the Scenic spot location system based on ZigBee technology is studied under the guidance of the architecture. Finally, based on the hardware platform of CC2430/CC2431 wireless ZigBee module, JLX12864G-1016 display module and DS18B20 temperature sensor module, the spot location and data acquisition and transmission are designed and realized. Data display and background monitoring of tourist location information are four software functions of positioning system.
