Problems solved by technology
[0003] However, at present, many buildings, such as shopping malls, have a large number of hollowed-out atrium areas, that is, hollow areas. Therefore, using the positioning method of closed floors, the positioning result error is relatively large, which seriously affects the accuracy of the user's floor positioning in the shopping mall.

Embodiment Construction
[0066] At present, since many shopping malls have atriums or hollow areas, the floor positioning of such shopping malls is quite different from that of closed office buildings. There is no atrium area in the office building, and the floors are closed. The signal on this floor will not penetrate or less penetrate to other floors. However, for shopping malls with an atrium, due to the existence of hollow areas, the signals between floors can easily be transmitted to other floors, which will interfere with the floor positioning of the shopping mall, resulting in inaccurate floor positioning.
[0067] In order to solve the above technical problems, the embodiment of the present application proposes to locate the floor of the building based on the strength of the wireless signal and the mutual influence between the floors. It can be a hotel, or a meeting place, etc. Of course, the solution provided by this application is also applicable to floors without atriums for positioning. ...

The application discloses a positioning method, device and system for positioning floors in a building. The building includes floor F, where F is an integer greater than or equal to 2; including: obtaining the wireless signal with the strongest signal among the collected wireless signals of the current frame from the floor Fa, and obtain the floor Fb that accounts for the largest proportion among the top N wireless signals in the wireless signal strength of the current frame; N is an integer greater than or equal to 2; obtain the wireless signal with the strongest signal received by each floor The first probability of the floor Fa, obtain the second probability that the wireless signal with the largest proportion among the top N signals received by each floor belongs to the floor Fb; determine the located floor according to the first probability and the second probability of each floor . The floor is determined by the signal strength ranking first and the top N signals, and combined with the probability that each floor receives the signal strength ranking first and the top N of the determined floor, various probabilities are considered from different dimensions, and the final positioning floor more acurrate.
Description
technical field [0001] The present application relates to the technical field of positioning, and in particular to a positioning method, device and system. Background technique [0002] At present, the positioning of floors is generally the positioning of closed floors, that is, each floor is closed except for the elevator and stair areas. The positioning of this kind of floor is relatively simple, because the signal interference between floors is very small and can be ignored. [0003] However, at present, many buildings, such as shopping malls, have a large number of hollowed-out atrium areas, that is, hollow areas. Therefore, the positioning method using closed floors produces large positioning results, which seriously affects the accuracy of user floor positioning in shopping malls. Contents of the invention [0004] The application provides a positioning method, device and system, which can accurately locate floors inside a building. [0005] The present application...
