In addition, it should be noted that, without conflict, the embodiments and features of the embodiments in the present application may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The bluetooth tag serves as a separate component that can be attached to clothing such as a child. The Bluetooth tag can carry out Bluetooth communication with the Bluetooth headset. Specifically, the Bluetooth headset is in two-way communication with the Bluetooth tag through the Bluetooth antenna array thereof.
Fig. 1 is a schematic flow chart of an alarm method for a bluetooth headset according to an embodiment of the present application, where when a user uses the bluetooth headset, an alarm is sent to the user in time when an object where a first bluetooth tag is located and an object where a second bluetooth tag is located are close to (or separate from) each other, and in this flow, from the perspective of a device, an execution body may be a control module inside the bluetooth headset; from the program point of view, the execution subject may be a program mounted on the bluetooth headset, accordingly.
The flow in fig. 1 may include the following steps 101 to 105.
Step 101, receiving a broadcast signal sent by a first bluetooth tag from a bluetooth antenna array.
Specifically, a bluetooth antenna array is set in the bluetooth headset, and a broadcast signal sent by the first bluetooth tag is extracted from signals received by the bluetooth antenna array. The first bluetooth tag is for example a bluetooth tag attached to an object (e.g. a child) to be protected. The second bluetooth tag in the following is for example a bluetooth tag attached to a dangerous object, such as a socket, a hot water kettle or the like. Each bluetooth tag may be distinguished by its bluetooth address. The Bluetooth tag corresponding to which Bluetooth address is the first Bluetooth tag and the Bluetooth tag corresponding to which Bluetooth address is the second Bluetooth tag are prestored in the Bluetooth headset.
Step 102, determining the direction of the first bluetooth tag relative to the bluetooth headset according to the received broadcast signal sent by the first bluetooth tag.
Specifically, the orientation of the first bluetooth tag relative to the bluetooth headset is determined, for example, using an AoA/AoD algorithm in the bluetooth protocol.
And 103, performing spatial filtering on the Bluetooth signals received from the Bluetooth antenna array to realize directional reception, wherein the received Bluetooth signals which are transmitted by the first Bluetooth tag to the direction of the Bluetooth earphone are subjected to signal enhancement processing, and the received Bluetooth signals which are transmitted in the other directions are subjected to signal suppression processing.
Specifically, the output signals of the bluetooth antenna array are weighted and filtered to generate a directional beam pointing along the direction of the bluetooth headset along the first bluetooth tag.
For example, if the first bluetooth tag is located directly above the bluetooth headset, the bluetooth signal in the downward direction is enhanced, and the bluetooth signals in other directions are suppressed.
Of course, the directional beam has a certain width, and the size of the width can be determined by experimental debugging.
Of course, the beamforming-based algorithm may also implement that the bluetooth antenna array transmits bluetooth signals directionally towards the first bluetooth tag, for example, by the bluetooth headset transmitting acknowledgement signals to the first bluetooth tag.
And 104, detecting a broadcast signal sent by the second Bluetooth tag in the spatially filtered Bluetooth signals, and carrying out alarm processing according to the detection result.
The spatially filtered Bluetooth signal can further embody information of the first Bluetooth tag in a direction opposite to the Bluetooth headset, and further can analyze direction or azimuth information of the second Bluetooth tag in the direction, so that whether the first Bluetooth tag and the second Bluetooth tag are in an undesirable approaching state or not can be automatically judged. Of course, it may also be automatically determined whether the first bluetooth tag and the second bluetooth tag are in an undesirably separated state (e.g., the first bluetooth tag and the second bluetooth tag should be in close proximity in normal circumstances).
The above bluetooth antenna array may be one, and then steps 101 and 103 are performed in a time-sharing manner. Of course, in most cases, a plurality of bluetooth antenna arrays are disposed in the bluetooth headset, so that the output of the bluetooth antenna array with better signal quality can be selected for analyzing the direction of the first bluetooth tag relative to the bluetooth headset (the direction is more accurate), and the output of the bluetooth antenna array with relatively poorer signal quality can be selected for spatially filtering the bluetooth signal propagating from the first bluetooth tag in the direction of the bluetooth headset. Specifically, hereinafter, the output of the bluetooth antenna array with poor signal quality is supplied to the beamformer. Since the outputs of the two bluetooth antenna arrays are used for different judgment purposes, they do not interfere with each other in time.
Optionally, the signal quality is determined from the signal strength and/or the signal to noise ratio.
In some embodiments, an alarm signal is issued in the event that the presence of a broadcast signal transmitted by the second bluetooth tag is detected in the spatially filtered bluetooth signal.
For example, the first bluetooth tag and the second bluetooth tag are both present in front of the bluetooth headset wearer, and the bluetooth headset emits an alarm signal. For example, to emit a warning tone, or to emit a vibration warning. If the Bluetooth headset is used, the Bluetooth noise reduction headset can also reduce the volume of the Bluetooth noise reduction headset and close the noise reduction function.
In some embodiments, in the event that the presence of a broadcast signal transmitted by the second bluetooth tag is detected in the spatially filtered bluetooth signals, locating the first bluetooth tag according to the bluetooth signals received from the first bluetooth antenna array, and locating the second bluetooth tag according to the spatially filtered bluetooth signals received from the second bluetooth antenna array;
and under the condition that the distance between the first Bluetooth tag and the second Bluetooth tag is smaller than a preset value, alarm processing is carried out.
That is, in the case that the first bluetooth tag and the second bluetooth tag are both close in direction and close in distance with respect to the bluetooth headset, the user is prompted that there is a possibility of danger.
How to determine the direction of the signal source according to the bluetooth signal can be calculated according to the prior art, which is not limited in this application.
Based on the same technical concept, the embodiment of the application also provides an alarm device for a bluetooth headset, which is used for executing the alarm method provided by any embodiment.

the risk determiner 3 is configured to detect a broadcast signal sent by the second bluetooth tag in the spatially filtered bluetooth signals, and perform alarm processing according to a detection result.
