Research On Indoor Positioning Technology Based On IBeacon

With the continuous development of network and mobile technology,the use of mobile devices more and more frequent,people rely on the phone is getting higher and higher.In this essay,the indoor positioning technology can be applied to the majority of app applications.The technology studied in this paper is mainly applied to small environment,closed environment,general said mainly used in indoor environment.The research of this paper is also based on the actual situation of indoor positioning technology research.People 70% of the time living in the indoor environment,the indoor environment location information service needs will be higher.In the positioning accuracy,the indoor positioning requirements will be significantly higher than the outdoor environment positioning requirements,the external environment,the reference object is relatively large,the proportion of the human body and the external size is much smaller,there is the existence of error,but the existence of the relative position is the user Use the feeling of the error on the small.However,relative to the indoor environment,relative to the external reference material size is much smaller,and the indoor environment is more complex.Therefore,the error for the indoor positioning,but also to strictly control.The main work of this essay: First of all,some of the more common indoor positioning technology for a brief introduction and analysis of the situation in practical applications,and then according to the actual situation of the environment,the establishment of RSSI distance measurement model.Filtering the collected data,first with the Gaussian filter method,after the average method.According to the model and the actual situation of the combination of the error of the algorithm to make up for the error.After the establishment of the distance measurement model,according to the way iBeacon is deployed in the actual environment,the three-point weighted centroid algorithm is designed.Finally,application of mobile phones to achieve the function in door positioning.To evaluate the feasibility of the iBeacon-based indoor positioning technology and positioning algorithm.Achieve the positioning function and automatic check-in function.
