Embodiment

[0136] Such as figure 1 As shown, it shows a flow chart of a method for judging the direction of a signal source provided in this embodiment, and the method for judging the direction of a signal source includes step S110, step S120 and step S130.

[0137] Step S110. Receive the first signal, the first signal includes the source signal sent by the source received by the first array element;

[0138] Wherein, the first signal is a cell signal received by the first antenna element in the receiving antenna that receives the signal source signal. The source signal includes a preset data sequence. The source signal includes a positioning frame, and the source transmitter transmits the positioning frame according to a certain frequency. The positioning frame can be based on the broadcast frame in the Bluetooth 4.2 protocol, or a custom protocol can be used. This method can be applied in the wireless communication process of any communication protocol and frequency band, not limited...

Abstract

The invention relates to the technical field of orientation, in particular to an information source direction judgment method, device, system and equipment and a readable storage medium. The information source direction judgment method comprises the steps: receiving a first signal, wherein the first signal comprises an information source signal sent by an information source received by a first array element; receiving a second signal, wherein the second signal comprises the signal source signal received by a second array element; and obtaining the information source direction according to the first signal and the second signal. According to the invention, a single T / R channel is adopted for signal receiving, so that the hardware cost and the system complexity are reduced; and due to the fact that a Bluetooth standard protocol is adopted for positioning, the information source applicability is wide, a currently universal Bluetooth 4.2 chip and Bluetooth 5.0 and 5.1 chips can be adapted, and the method is generally suitable for terminals such as mobile phones, intelligent hardware and the like.

Description

technical field [0001] The present application relates to the technical field of orientation, and in particular, relates to a method, device, system, equipment, and readable storage medium for judging the direction of a signal source. Background technique [0002] Due to various reasons, the existing single-channel signal source direction judgment system based on antenna array generally has low accuracy. Therefore, how to improve the accuracy and precision of signal source release judgment has become a technical problem to be solved urgently in this field. Contents of the invention [0003] The purpose of the present application is to provide a method, device, system, equipment and readable storage medium for judging the direction of a signal source, so as to improve the above problems. [0004] In order to achieve the above purpose, the embodiment of the present application provides the following technical solutions: [0005] In the first aspect, the embodiment of the p...
