[Abstract]:With the rapid development of information technology, mobile positioning has become a major demand of people's daily life. The research on outdoor GPS positioning has become more and more mature, people urgently hope that indoor positioning and outdoor positioning can be jointed seamlessly. In recent years, researchers at home and abroad have done a great deal of work on indoor positioning, and put forward various kinds of use of different signal carriers, However, the study of floor location in the field of indoor location is still in the initial stage. Many studies ignore the determination of the floor, or directly artificial designated floor, Or using hardware equipment to obtain altitude information, and floor positioning has its special application value and user needs, so it is necessary to use software scheme and algorithm to study floor location in the future. For the first time, this paper summarizes the limited literature in recent years, and proposes a FLOC floor location scheme based on RSSI signal analysis, which abstracts the floor location into a data analysis model to solve the problem of floor location. The main contributions and innovations of this paper are as follows:. 1) in view of the lack of research on the direction of floor positioning, this paper investigates and analyzes the existing indoor positioning and floor positioning methods, analyzes its technical characteristics and points out its shortcomings. (2) considering the characteristics of RSSI value of WiFi signal across floors, the barrier effect of floor laminates is quantitatively analyzed, and a FLOC solution based on signal analysis is proposed. 3) abstracting floor location into data analysis problem creatively, applying hidden Markov model and cluster analysis to floor location for the first time, improving forward and backward algorithm to apply to FLOC scheme, and evaluating the performance of the model by comparing four sets of parameters. The positioning accuracy is up to 100% in specific parameters. 4) verify the FLOC scheme on the Android platform, realize by crowdsourcing and using the ready-made hot spot facilities, do not need the field investigation, and the cost is low. 5) develop the fire escape app, and apply it to it. The experiment shows that the combination of floor positioning in location application is more flexible and intelligent than traditional manual setting.
