Research On The Location System Of Scenic Spots In Lhasa Tourist Scenic Spot Based On ZigBee Network

As a pillar industry of China's national economy,not only can tourism effectively boost the regional economy,but also the improvement of information technology of tourist attractions cancontribute to the modernization of the attractions and accelerate the pace of urbanmodernization.Therefore,Lhasa hasissuedthe goal of the tourism industryfrom 2016 to 2020,whichwill invest 100 billion yuan to build a smart travel system and furtherthe construction of Internet of things(IoT)in tourism.IoT technology usually refers to a network technology that can connect any item to the Internet according to the agreement for information exchange and communication by using of radio frequency identification(RFID),infrared sensors,GPS,laser scanners and other information sensing equipmentto realize intelligent identification,tracking,monitoring and management.And ZigBee technology is one of the supporting technologies of Io T technology.Compared with other wireless positioning technology,ZigBee technology can provide network with the advantages of low price,low power,small scale,low rate,and large network capacity,thus it can be seen that the technology can better enhance the scenic quality of service.Based on the research of the topology and routing algorithm of ZigBee network,this thesis puts forward the research on location system of scenic spot in Lhasa tourism scenic area based on Zig Bee network.This article adopts threeresearch methodsfor the different research content,includingthe literature analysis,the simulation and the physical system construction.Among them,the literature analysis is mainly used for thetheoretical study of ZigBee technology and ZigBee network performance optimization;thesimulation is mainly concerned with the research about the effect of network size on network performance;and the physical system construction mainlyimplements the location system of tourist attractions in Lhasa scenic spot.Accordingly,there are three research outputs in this thesis.First,through analysis of the literature the thesis gets two conclusions: oneis that the research of ZigBee network performance optimization consists ofnetwork topology optimization,routing algorithm optimization and parameters optimization for other protocol layers(such as superframe parameters in beacon mode for MAC layer);the other is that the research of relationship between ZigBee network performance and network size is limited not only to the theoretical research but also tothe network performance in a small range of network size.Second,the research makes use of the network model provided by OPNET simulation software to design simulation experiment,collect index data of load,throughput and delay based on the literature analysis.And thenthe study points out that the number of router equipment and terminal equipment in the laboratoryenvironmentshould be controlled in the range of 29-33 and 63 – 84 in order toimprove ZigBee networkperformance through analysis and comparison.Third,the researchproposes the design framework of intelligent scenic area architecture based on ZigBee Technologyand discusses hardware and softwaredesign ofscenic location system based on ZigBee technology in detailguided by architecture.After thatthe studyuses CC2430/CC2431 wireless MCU with the system on chip solution,JLX12864G-1016 display module and DS18B20 temperature sensor to build the hardware platform,and realizes foursoftware functions of the location system comprised ofthe positioning of scenic spot in Lhasatourism scenic area,dataacquisition and transmission,data display and the backstage monitoring of tourist location information.
