Abstract

The invention discloses a Bluetooth system, a Bluetooth device and a direction identification method of Bluetooth signals. The Bluetooth system comprises a chip, a first antenna, a second antenna, a transfer switch and a signal strength acquisition module, wherein the second antenna has a predetermined distance from the first antenna in a first direction; the transfer switch receives and controls signals to connect the first antenna with the chip or connect the second antenna with the chip; and the Bluetooth chip comprises the signal strength acquisition module, and the signal strength acquisition module is used for acquiring the wireless signal strength of the first antenna and the second antenna. The Bluetooth system disclosed by the invention is provided with at least two antennas so as to receive the Bluetooth signals from different directions, the direction of a Bluetooth signal source can be obtained by calculating different signal strength of different antennas, and thus direction identification of the Bluetooth signal source can be achieved.

Description

technical field [0001] The invention relates to wireless transmission technology, in particular to a bluetooth system, equipment and a method for identifying the direction of bluetooth signals. Background technique [0002] Bluetooth transmission is a kind of wireless transmission technology. Its signal has many characteristics such as omnidirectional, wall-penetrating, and can be reflected, mirrored, and diffracted between objects. [0003] In the prior art, most Bluetooth products are used in the omnidirectional Bluetooth transmission path, but in the application scenarios that require direction recognition, the omnidirectional transmission path limits the use of Bluetooth, and because the direction cannot be recognized, It also reduces the safety of the product. Contents of the invention [0004] The purpose of the present invention is to provide a bluetooth system, equipment and a method for identifying the direction of bluetooth signals, so as to solve the problem th...
