Abstract

The invention relates to the technical field of data processing, and provides a positioning method, a positioning device and terminal equipment. The positioning method comprises the following steps that phases of positioning signals received by each antenna in an antenna array of the positioning device is obtained, wherein the number of antennas in the antenna array is more than 2, and the antennaarray comprises at least one directional antenna and / or the receiving ends of at least three antennas in the antenna array are not on the same straight line; according to the distance between the antennas, the phase difference of the same positioning signal received by the antennas and the wavelength of the positioning signal, approximate calculation is carried out by using a trigonometric function to obtain the standard distance between each antenna and a positioning signal transmitting point in a plane coordinate system; and the standard relative position of the positioning device and the positioning signal transmitting point is determined according to the standard distance between each antenna and the positioning signal transmitting point. The problems of high cost, poor precision andeasy interference caused by arranging a plurality of positioning signal sources in an existing positioning mode are solved.

Description

technical field

[0001] The present application belongs to the technical field of data processing, and in particular relates to a positioning method, device and terminal equipment. Background technique

[0002] With the development of science and technology, people can determine their location through GPS positioning, Beidou positioning, Galileo system positioning, mobile phone base station positioning, WIFI positioning, ZIGBEE positioning, Bluetooth positioning and other positioning methods.

[0003] The current positioning methods basically use the terminal to receive positioning signals from multiple positioning signal sources in space, and use the triangulation method to achieve positioning according to the signal strength (such as RSSI) or time phase difference (such as GPS). Under ideal conditions Under the circumstances (if there is no interference from obstructions), the accuracy of positioning through these positioning methods is relatively high, but when these posit...
