Embodiment 1

[0110] see figure 1 , figure 1 It is a schematic diagram of a terminal positioning method provided in Embodiment 1 of the present invention. This embodiment describes in detail the technical solution of the terminal positioning method provided by this embodiment from the perspective of a positioning server. Wherein, when implementing the terminal positioning method provided in this embodiment, it is confirmed that N wireless access devices and several sampling points are set in the positioning area, and N is greater than or equal to 3. Such as figure 1 As shown, the terminal positioning method provided in this embodiment includes the following steps:

[0111] S10. The positioning server receives the access signal strength values ​​of the terminal relative to at least three of the N wireless access devices sent by the terminal;

[0112] Then execute step S20 according to the access signal strength values ​​of the terminal relative to at least three of the N wireless access ...

Abstract

The embodiment of the invention discloses a terminal positioning method and related equipment and system. The terminal positioning method and related equipment provided by the embodiments of the present invention determine the access signal strength value of the terminal in the positioning area for the wireless access device by receiving the access signal strength value of the terminal for the wireless access device sent by the terminal Contour, select the triangular area that several access signal strength value contours pass through to query the location of the positioned terminal, without establishing a specific propagation attenuation model, the scheme is simple, can be widely used, and improves the application of the terminal positioning method universality. Moreover, the cluster analysis method is further used to find the optimal solution in the candidate triangular area to determine the position of the terminal, so that the positioning accuracy is more accurate. And taking obstacle information into account while performing triangular division on the planar view of the positioning area, the effect of multipath propagation is also reduced, and the positioning accuracy is further improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a terminal positioning method and related equipment and systems. Background technique [0002] At present, the demand for indoor positioning is very extensive, and it is mainly used in many fields such as social networking, personnel tracking, asset management, financial security, objects, the elderly, children's location search, and emergency services. [0003] Indoor positioning technology has become an important query method, and the existing indoor positioning technology is mainly realized by the propagation model method or the location fingerprint method. The current propagation model method needs to convert the attenuation of the propagation signal into the propagation distance of the propagation signal according to the propagation attenuation law of the propagation signal indoors when determining the position of the terminal, and then according to the prin...
