Abstract

The invention relates to a positioning method, device and system, a receiving node, a transmitting node and a storage medium. The positioning method comprises the steps of: obtaining positioning signals broadcasted by a plurality of transmitting nodes respectively, and extracting feature information carried by target positioning signals broadcasted by each transmitting node, wherein the feature information is used for representing the broadcasting direction of the target positioning signals broadcasted by the transmitting nodes; screening out at least one target node group from the plurality of transmitting nodes according to the broadcasting direction, wherein each target node group comprises at least two target transmitting nodes; and positioning the receiving node according to the position information of each target transmitting node in each group and the broadcasting direction corresponding to each target transmitting node. The positioning method can improve the positioning accuracy.

Description

technical field [0001] The present application relates to the technical field of positioning, and in particular to a positioning method, device, system, receiving node, transmitting node and storage medium. Background technique [0002] At present, the commonly used positioning method mainly uses a received signal strength indication (Received Signal Strength Indication, RSSI) for positioning. RSSI positioning refers to transmitting positioning signals to the terminal through three base stations that are not collinear with each other. When the terminal receives the positioning signal, it analyzes the positioning signal to obtain the RSSI value of the positioning signal, and then determines the straight-line distance to the three base stations according to the RSSI value. , and then use the straight-line distance between the terminal and the three base stations as the radius to make a circle, and the point where the three circles intersect is the location information of the t...
