Abstract

The invention provides a multi-beam positioning method, device and system, wherein the multi-beam positioning method comprises the steps of: receiving beam signals sent by a signal point to be positioned by using a directional antenna in multiple sets of alternative directions, and calculating the field strength of the beam signals in the multiple sets of alternative directions; calculating the field strength difference value of the beam signals in each set of alternative directions, and, when the field strength difference value is greater than a set threshold value, determining an area corresponding to the direction having a relatively high field strength value in each set of alternative directions as the initial position area, where the signal point to be positioned is; and, determiningthe overlap area of the signal point to be positioned in the initial position area in each set of alternative directions as the relative position area of the signal point to be positioned.

Description

technical field [0001] The invention relates to the field of signal positioning, in particular to a multi-beam positioning method, device and system. Background technique [0002] RSSI (Received Signal Strength Indication) refers to the received signal strength indication, a positioning technology that measures the distance between the signal point and the receiving point through the strength of the received signal, and then performs positioning calculations based on the corresponding data [0003] At present, according to the received RSSI value, the distance between the signal receiving end and the signal transmitting end is usually calculated by the following traditional method, that is, the distance is fitted by using the large-scale fading of the signal in space, from the theoretical and practical In terms of measurement, if a free space model is used, the average received signal power RSSI value decreases logarithmically as the distance increases. [0004] The free sp...
