| Passengers are often lost because of the huge area and complex structure of the airport boarding building,so the demand for the intelligent service system for airport passengers which can provide accurate indoor positioning is increasing day by day.With the increasing variety of integrated sensors in mobile intelligent devices and the improvement of precision,it is possible to collect accurate fingerprint data through mobile intelligent devices.The method of multi-mode fusion positioning by collecting fingerprint information such as Bluetooth,Wi-Fi,geomagnetism and air pressure by terminal device sensors solves the problem of inaccessibility of positioning caused by the inability of satellite signals to penetrate buildings,so as to achieve indoor precise positioning.This creates the necessary conditions for the design and implementation of the airport passenger intelligent service system.Despite the urgent need for such software,it is very scarce in China at present,so it is of great significance to design and implement the airport passenger intelligent service system.Existing technical frameworks such as OkHttp and ARouter provide good technical support for efficient,stable and secure services.On the basis of the above framework and the functional and non-functional requirements analysis of airport passenger services,this paper establishes a differentiating hierarchy and distinguishing modules architecture which takes ARouter as the core,and divides the project into five parts as positioning and navigation module,e-commerce platform module,airport service module,personal center module and system management module.By analyzing the function of each module,the design of database table and back-end access interface,detailed design of system and code are completed.Finally,functional and non-functional tests are carried out on the completed servers and clients,and then the problems tested have been fixed.The airport passenger intelligent service client completes the positioning function in both indoor and outdoor scenes,and automatically completes the switching between indoor and outdoor positioning.The system provides the whole-journey housekeeping service for passengers traveling by air.It is an attempt to extend the results of laboratory indoor positioning to practical application. |
