Method and device for determining position of positioned equipment, and base station

Abstract

The invention discloses a method and a device for determining the position of positioned equipment, and a base station. The position of the positioned equipment can be determined only by depending onthe single base station, so that the arrangement number of base stations is greatly reduced, and the position of the positioned equipment can still be determined in an environment with relatively lowbase station density; and in addition, the position determination method only needs to determine the distances between the equipment and the base station before and after the equipment is moved each time, and a movement distance and a moving angle when the equipment is moved each time, the operation is simple and convenient, and when the positioned equipment is moved, the higher the movement frequency is, the more the direction changes are, and the more accurate the position of the finally obtained positioned equipment is, so that the accuracy of the determined position is greatly improved.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a method, a device and a base station for determining the position of a positioned device. Background technique [0002] When determining the location of a located device, the most common method is triangulation with the help of multiple base stations, for example, as figure 1 As shown, the distances between the positioned device p and three base stations (such as a1, a2 and a3) are respectively measured to obtain three distance values, namely L1, L2 and L3; and a3) as the center of the circle, draw three circles with three distance values ​​(such as L1, L2 and L3) as the radius, and the intersection position of the three circles is the position of the positioned device p. [0003] However, although the above method of determining the position is relatively simple, it is necessary to deploy multiple base stations in advance to determine the position of the positioned d...
