Research And Design Of Scenic Spot Automatic Navigation Software System Based On Base Station Location

With the vigorous development of the tourism industry,the number of domestic tourists has reached new highs.However,the development of the Internet has not changed the way people visit scenic spots.First of all,tourists are not impressed by the guide boards and interpretation of tour guides,and the tour guide experience is not good,which makes the tour become a photo opportunity.Secondly,in scenes with weak GPS signals,such as indoor attractions,tourists are unable to locate through the map APP in their mobile phones,It will wast a lot of time to find the attractions they want to go,and reducing the travel experience.In addition,the staff of the scenic spot also lack access to information such as tourist help information,tourist flow in the scenic spot,and real-time distribution of tourists.Therefore,this thesis understands and grasps the needs of tourists and scenic area staff through questionnaire surveys and visits,and designs and develops base station positioning,voice guidance,graphic guidance,emergency assistance,scenic area evaluation,and navigation based on this.The scenic administrator system has functions such as POI(Point of Information)management,scenic area administrator management,help-seeing viewing,visitor flow statistics,and real-time display of tourist distribution.The two systems constitute the software system of scenic spot automatic navigation.Firstly,This thesis introduces the positioning method of the base station.After comparing multiple positioning methods,the TOA(Time of Arrival,signal arrival time)method is picked for positioning.Based on the TOA positioning method,the NLOS(Non Line of Sight,non-Line-of-sight)error,and analyze the law of NLOS error graphically,establish the NLOS error model of linear regression,and finally complete the linear regression least square base station positioning algorithm and test it.Secondly,a WEB system based on B/S architecture is designed and developed on the basis of demand analysis.Since HTML5 does not currently have the ability to acquire Android native,it takes the method of developing Android plug-ins and using HTTP protocol to send base station information to the back end,thereby obtaining base station information,and using base station positioning algorithms to process base station information to achieve positioning.And according to the demand,the scenic area administrator system and the tourist system are functionally designed from the two perspectives of scenic area administrators and tourists.According to different functional requirements,the database E-R diagram is designed to complete the design of the database table.Finally,using SSM framework and Spring boot framework,RESTful architecture and MVC development model has completed backend development.The front-end development was completed through the JQuery framework,HTML5,CSS3,and Thymeleaf template engine.Ajax technology was used to transfer data between the front and back ends,and the system function test was finally completed.Using the tourist subsystem of the system,tourists can experience basic functions such as audio guide,graphic guide,base station positioning,scenic spot evaluation,navigation,etc.In case of difficulties or dangerous situations,they can also complete help through this system.According to the help information,the location of the tourists will be locked in the map to provide timely help;using the administrator subsystem of the system,the administrator can not only edit the navigation information of the scenic area,view and reply to the tourists' comments,view the tourists for help,but also Perform managerial affairs such as attendance of the administrator,personnel management,counting passenger flow,and viewing the real-time distribution of tourists.
