Implementation Of Intelligent Bus WiFi System Based On OpenWRT

With the development of Internet technology,the applications of the Internet of things technology are entering into our daily life gradually and make our lives more convenient.On the one hand,the realization of the Internet of things based on three main network configurations including Internet,mobile communication network and wireless sensor network,routers play a key role in the Internet information resources sharing.On the other hand,the development of the Internet of things have promoted the new concept of smart city and smart home,intelligent routers'research lay the solid foundation for the intelligent life.Bus WiFi technology is a WiFi network service system with the fusion of traditional Operators 3G/4G technology,providing the public Internet access.At present,due to the explosive growth of the mobile Internet users,the potential of bus WiFi market is tremendous,the demand of the bus WiFi throughout each line of public transport,bus WiFi system can bring users a series of service online like video entertainments,news and real-time network communication and so on.Paper starts from the working principle of intelligent router and work on the router system as the main research points,and then design the intelligent router system.At first,the main research content is how to design and build OpenWRT system on a router.This system can realize the access to the Internet in the bus and local resources browsing capabilities,meeting the basic requirement of the public on the Internet for users.Second,the system can realize intelligent terminals' WIFI signal collection inside the bus,using the AP scanning technology to detect the terminals which open WiFi function for data statistics.On this basis,in order to realize the analysis of the passengers inside buses,this paper builds a mathematical model to analysis of bus passengers flow.Finally,based on the bus passengers flow data collection,this paper designs an original and destination(OD)matrix analysis.Using OD historical datas to export the simulation from the status quo of the distribution of traffic volume,as a tool of calibrating correction for traffic lines' distribution,making the established transportation network more according to the actual needs.This paper designs and implements of intelligent bus WiFi system to make passengers access wireless Internet and browse the local media,and provide function of data acquisition for the bus operating companies.Then better planning bus lines,thus avoiding buses' resources reuse,uneven coverage and other issues.
