Research On Intelligent Parking System For Indoor Navigation Based On Wireless Network

The development of the Internet of Things makes people's lives convenient.It's important for users to find parking spaces quickly in indoor parking lots,which can save time and improve user satisfaction.Therefore,the research of indoor navigation intelligent parking system has positive significance for improving the convenience of people's life and the efficiency of parking lot management.Compared to various wireless devices,including Zig Bee,Wi Fi,RFID,UWB,etc.,and finally chose Zig Bee as a hardware device.Research on Zig Bee helps master its working principle and networking mode.The integrated development environment IAR is used to develop and debug program to obtain suitable environment parameters and distinguish devices like coordinators,terminals and routers based on different codes.To better collect data and use less devices,the placement of terminal is also obtained through experimental analysis.Secondly,after analyzing a variety of positioning algorithms,a deterministic algorithm based on the fingerprint database(traditional KNN algorithm)is selected.Algorithms determine the positioning result.In order to improve the positioning accuracy of this method,after the fingerprint data is collected,considering that these offline data conform to the normal distribution,the Gaussian function is used to weight the KNN algorithm,and the results of the algorithm running are compared by MATLAB program.The results show that Gaussian function weighting is better than traditional KNN and ordinary weighted method based on inverse distance.Due to the small changes in the indoor parking environment,this positioning method has good applicability.This is also very helpful for the research of navigation.The navigation is to start from the real parking lot,design some indoor maps,and simulate the navigation function.After selecting the start and end points,a reference route is calculated and provided to the user.Finally,the design and implementation of the management system is based on the basic needs of the parking lot,including functional modules such as registration and registration,parking management,navigation functions,timing charges and bill viewing.The system is developed in the form of web.The entire web system uses Spring,My Batis and Spring MVC frameworks.The database is My SQL.The technologies used in front-end pages include jsp,JQuery and Page Helper plugins to complete the paging function.
