Dual directional antenna beacon device, system and method with controllable emission direction

Abstract

The invention discloses a bi-directional antenna Beacon device with a controllable emission direction, a system and a method. The device comprises two Beacon emission modules, a metal directional shielding body and a directional antenna separation sheet. The Beacon emission module comprises an antenna. Two directional openings are arranged in the metal directional shielding body. The Beacon emission modules are arranged on two sides of the directional antenna separation sheet. Antenna assembling faces of the Beacon emission modules face corresponding directional openings of the metal directional shielding body. The system comprises a Beacon signal directional emission end and a Beacon signal directional receiving end. In the method, the emission of Beacon signals is adjusted through the metal directional shielding body, and multi-azimuth reception is achieved through the Beacon device. According to the invention, a problem of mutual interference caused by overlapping of signal covering regions is solved, and signal recognition degree is improved.

Description

technical field [0001] The invention relates to the field of bluetooth communication, in particular to a Beacon device, system and method with controllable emission directions and dual directional antennas. Background technique [0002] Ordinary Beacon is a broadcast protocol based on the low-power Bluetooth protocol, and it is also a low-power Bluetooth device (slave) with this protocol. As a Beacon device, it is usually placed in a fixed position indoors or outdoors, so as to continuously broadcast to the surroundings. However, the antenna of a conventional Beacon is non-directional, centering on the Beacon arrangement point, and covering the surrounding space in the form of a circular area or a fan-shaped area. Such a design has a very large overlapping area of ​​signal coverage of multiple different nodes in some specific application scenarios, which is likely to cause mutual interference and lead to false positives, missed negatives, and false positives. [0003] The ...
