Design Of Positioning And Navigation System In Metro Station

Today,positioning navigation system in a wide range of uses,such as car GPS positioning system,mobile phone positioning and so on.But in the metro station,especially in the complex traffic transfer station,how to provide passengers to locate the navigation information,so that passengers quickly and accurately find the destination,this information system research is still in its infancy.Therefore,this paper introduces the design of the navigation system in the metro station.First of all,the value and purpose of this study are summarized,and expounds the research status and research methods and structure of the subject.This paper discusses the technology of the navigation system in the metro station,discusses the common positioning technology in the metro station,discusses the commonly used positioning method and the common positioning algorithm in the metro station,and details the Dijkstra navigation algorithm and the A * navigation algorithm,choose A * navigation algorithm in this paper.And finally summarizes the other related technologies applied at the end of the theory.Secondly,the main application of RFID technology in this paper is introduced,and the basic components,basic working principle and frequency classification of RFID are introduced respectively.The application of RFID technology in metro station location scenario is introduced.The design of the navigation system in the metro station is put forward after the design of the navigation system in the metro station is carried out.Finally,this paper designs the software of positioning navigation system in metro station,and designs the route generation,location query flow and map browsing program in metro station respectively.It is expected that the research design of this paper will provide some reference for the design of the navigation system in the metro station.
