[0114] Based on the first embodiment, the second embodiment of the system for indoor positioning using wireless hotspots of the present invention is proposed, and this embodiment also includes:

[0115] The storage module 40 is used to save the obtained position information; the generation module 20 is also used to generate the motion trajectory of the user terminal according to the saved user terminal position information; the storage module 40 is also used to save the motion of the user terminal track.

[0116] Indoors, a unified Internet access function can be configured for all hotspots, and a large database can be set up to store the calculated location information of the client. The location information includes multiple coordinates or coordinate value ranges, the province information of the client, and the The storage time and / or storage order of the location information is based on the saved location information of multiple user terminals and the storage time and / or st...

[0118] Based on the second embodiment, the third embodiment of the system for indoor positioning using wireless hotspots of the present invention is proposed. In this embodiment:

[0119] The generation module 20 is also used to determine the location of the hotspot where the search module 10 is located and all the hotspots when only the hotspot where the search module 10 is located can search for the user terminal and the generation module 20 does not generate a location overlapping area in the hotspot where the search module 10 is located. The non-overlapping area of ​​other hotspots in the signal coverage area; also includes an acquisition module 50, which is used to determine the Z-axis coordinate range value of the current position of the user terminal according to the movement trajectory of the user terminal within a preset time saved in the storage module 40, And according to the user terminal current position Z-axis coordinate range value and the linear distance between...

Abstract

The inventionrelates to a method and system for conducting indoor positioning through wireless hotspots. When a user does not move, other adjacent hotspots are looked up through the hotspot providing a user terminal entering request, overlapping zones where a plurality of user terminals are located are generated through the adjacent hotspots, then the overlapping zones are overlapped again so that a shared overlapping zone of the overlapping zones can be obtained, and position information of the user terminals can be calculated according to the obtained shared overlapping area. Therefore, when the user does not move, the user terminals can still be positioned accurately.

Description

technical field [0001] The present invention relates to the technical field of wireless positioning, in particular to a method and system for indoor positioning using wireless hotspots. Background technique [0002] With the development of science and technology, the application of positioning system in people's life is becoming more and more extensive. Ordinary mobile clients generally use GPRS for positioning. It is almost impenetrable when it is exposed to objects, affecting the accuracy of its positioning. In this case, the prior art proposes a method of using wireless access points for indoor navigation. When the user end receives signals from three or more wireless access points, it The distance between them and the location information of the wireless access point are used to locate the client. In the prior art, 3 or more fixed wireless access points must be used to complete the positioning of the user terminal, and when the user does not move and there are only fix...
