Terminal positioning method, related device and terminal positioning system

Abstract

The embodiment of the invention discloses a terminal positioning method, a related device and a terminal positioning system. According to the terminal positioning method and the related device which are provided by the embodiment of the invention, access signal strength value contour lines of a terminal in a positioning region relative to wireless access devices are determined by receiving access signal strength values, sent by the terminal, of the terminal relative to the wireless access devices, and a triangular region through which a plurality of access signal strength value contour lines pass is selected to query the location of a positioned terminal. No special propagation attenuation model needs to be established. The scheme is simple and can be widely used, and the application universality of the terminal positioning method is improved. Moreover, the optimal solution in a candidate triangular region is found through a clustering analysis method to determine the location of the terminal, which makes the positioning accuracy higher. Obstacle information is taken into consideration while triangularized region division is performed on the floor plan of the positioning region, thus reducing the multipath propagation effect and further improving the positioning accuracy.

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...
