Abstract

The present invention provides a method and device for positioning a terminal. The method includes the following steps that: the change value of the strength of signals received by receiving ends is acquired when signals are transmitted between a plurality of positioning antennas and a terminal to be positioned, wherein the receiving ends are the plurality of positioning antennas or the terminal to be positioned; the azimuths of the plurality of positioning antennas relative to the terminal to be positioned are determined according to the change value of the strength of the signals; and the location of the terminal to be positioned is determined according to the azimuths of the plurality of positioning antennas relative to the terminal to be positioned and distances between the plurality of positioning antennas. With the method and device of the invention adopted, the problem of low positioning accuracy or heavy workload during the positioning of an indoor terminal in the prior art can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for locating a terminal. Background technique [0002] In the existing related technologies, the terminal method generally uses transmission time, transmission time difference, signal attenuation degree, etc. to calculate the distance between the target and the positioning antenna. However, the indoor positioning distance is short, and the target distance is calculated using the transmission time. Taking a distance of 100 meters as an example, it only takes 3.33e-7s for the electromagnetic wave to transmit 100 meters, and the accuracy of conventional clocks is difficult to achieve. Moreover, the indoor positioning environment is complex, and the degree of signal attenuation is seriously affected by the environment, so it is impossible to accurately estimate the distance based on the attenuation. And the system efficiency of the terminal under test has a gre...
