Research And Implementation Of Indoor Bluetooth Positioning Based On Android Platform

In recent years,with the rapid development of smart devices,it has become a reality that people are positioning services on mobile,making people use the mobile side of the indoor location location service more and more become a reality,the domestic information technology research will be more energy into the indoor positioning of technology research and development.In 2013,Apple Inc.launched i Beacon Bluetooth signal station base on Bluetooth Smart technology,i Beacon positioning service is very prominent feature,through the deployment of i Beacon station to achieve indoor navigation and real-time positioning tracking,and pushing information through Bluetooth,i Beacon provide a very good experience In the mall retail or some public service areas such as the stadium,museum.In particular,Bluetooth has a good transmission distance,low power consumption,and signal encryption makes i Beacon in the future of Internet of Things technology applications will play a pivotal role.This paper studies indoor Bluetooth positioning based on android platform,the positioning of the hardware and software implementation to do a detailed description.First of all,by consulting a large number of literatures,the principle and advantages and disadvantages of indoor positioning system at home and abroad are analyzed,and the factors of interference of indoor positioning are analyzed for different schemes.Secondly,this paper is based on the advantages of i Beacon for indoor positioning.Then the demand analysis of the i Beacon-based indoor positioning system is put forward.The platform and environment of software development are analyzed,and the overall framework design of the positioning system is carried out.The logical structure of the whole system is given.Secondly,this paper analyzes the advantages of i Beacon for indoor positioning.Introduced the mainstream positioning algorithm again,including indoor positioning technology based on distance algorithm and indoor positioning technology based on non-distance algorithm,and then analyzed the loss of Bluetooth signal path propagation process.Then,the hardware and software design and implementation of i Beacon base station are described,and the prominent function of the research process is analyzed.And then the paper introduced the android platform and based on the android platform for indoor positioning design method.Analyzed the technical parameters of the whole system,power consumption description,debugging development,principle design and so on.Finally,in the real environment for the construction of the test environment,Based on the indoor positioning system proposed in this paper in the above environment for testing and analysis,and gradually set up the i Beacon environment,respectively,a single multi-point test,a single multi-point test,different temperature test,and the test results and experimental data Analysis,find differences in different environments.The technical scheme described in this paper can achieve accurate positioning effect.Through the base station in the test site deployment and joint testing,indoor Bluetooth positioning accuracy can reach about 1 meter,basically meet the technical requirements of Internet of Things applications.
