exemplary method

first embodiment

As shown in FIG. 1 , an embodiment of the present invention provides a Bluetooth-based mobile terminal distance reminder method, and the Bluetooth-based mobile terminal distance reminder method can be used in mobile devices such as mobile phones, tablets, and wearable devices. The method described in the embodiment of the present invention includes the following steps:

Step S100, the second Bluetooth mobile terminal scans to obtain surrounding Bluetooth signals, and detects the linear distance between the surrounding first Bluetooth mobile terminal and the second Bluetooth mobile terminal through Bluetooth timing;

The mobile terminal used in the embodiment of the present invention may be a mobile phone with a Bluetooth function, a wearable mobile phone, and the like. For example, the second Bluetooth mobile terminal may be user B's mobile phone with Bluetooth function, and the first Bluetooth mobile terminal may be user A's mobile phone with Bluetooth function. For example, mobile phone A of user A is called advertiser (broadcaster), and mobile phone B of user B is called scanner or observer (scanner).

Wherein, before the second bluetooth mobile terminal scans and obtains surrounding bluetooth signals, and regularly detects the linear distance between the surrounding first bluetooth mobile terminal and the second bluetooth mobile terminal through bluetooth, the steps include:

The first bluetooth mobile terminal turns on the broadcast sending mode, and continuously sends the bluetooth broadcast to surroundings. The data carried in the broadcast is agreed data of 31 bytes.

In this embodiment, for example, the mobile phone A of user A in the broadcast state continuously sends broadcasts, and can carry 31 bytes of data when sending broadcasts; the second bluetooth mobile terminal scans and acquires surrounding bluetooth signals every time it passes through a certain period of time, The straight-line distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is detected through the acquired Bluetooth signal.

Before the second bluetooth mobile terminal continuously scans and obtains the broadcast of the first mobile terminal, and detects the step of the straight-line distance from the first bluetooth mobile terminal, it also includes: the first bluetooth mobile terminal uses the agreed data as the broadcast carrying data, and generates Bluetooth broadcast, the Bluetooth broadcast is broadcast data used to realize distance detection between two or more Bluetooth mobile terminals, and the data carried in the broadcast is agreed data of 31 bytes. At the same time, the first Bluetooth mobile terminal turns on the broadcast sending mode, and continuously sends the Bluetooth broadcast carrying the agreed data to the surroundings.

Specifically, as shown in FIG. 2, step S100 includes:

Step S101, the second Bluetooth mobile terminal scans and obtains the Bluetooth broadcast of the first Bluetooth mobile terminal around, and analyzes the broadcast data carried by the Bluetooth broadcast to obtain the Bluetooth signal strength of the broadcast sender;

Step S102 , the second Bluetooth mobile terminal calculates the straight-line distance from the broadcast sender's first Bluetooth mobile terminal according to the broadcast sender's Bluetooth signal strength.

For example, for example, there are two user A and user B carrying mobile phones in a square, and the mobile phones of user A and user B turn on the Bluetooth function at the same time. The mobile phone of the user B continues to send a Bluetooth broadcast with 31 bytes of agreed data to the surroundings through the Bluetooth function. The Bluetooth broadcast containing the agreed data includes at least a header and a data part, and the data may include a mobile phone used to indicate the sending data. The identification segment of the device number and the data segment that enables it to realize the distance measurement between two mobile phones and the function of prompting that the distance is too close. When the straight-line distance between user A and user B reaches, for example, within 5 meters, user A's mobile phone starts to obtain it through Bluetooth. The bluetooth broadcast sent by the mobile phone of user B, the mobile phone of user A receives the bluetooth broadcast, parses its broadcast data into the broadcast data used to detect the distance between two mobile terminals, and obtains the signal of the bluetooth broadcast sent by user B's mobile phone For example, the strength is -69.4dBm, and the calculated straight-line distance between user A's mobile phone and user B's mobile phone is about 5m; After obtaining the Bluetooth broadcast sent by the mobile phone of user B, the mobile phone of user A receives the Bluetooth broadcast, parses its broadcast data into broadcast data for detecting the distance between mobile terminals, and then obtains the Bluetooth broadcast sent by the mobile phone of user B. The broadcast signal strength is, for example, -56.5dBm. It is estimated that the straight-line distance between the mobile phone of user A and the mobile phone of user B is about 0.9m.

Further, step S200, judging whether the straight-line distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is less than a predetermined distance;

In this embodiment, it is determined whether the straight-line distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is less than a predetermined distance based on the calculated straight-line distance between the two mobile terminals.

Specifically, as shown in FIG. 3, step S200 includes:

Step S201, comparing and judging the detected linear distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal with a preset predetermined distance;

Step S202, judging whether the straight-line distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is less than a predetermined distance;

For example, for example, when the distance between the two mobile phones is less than 1 meter, the reminder distance is preset. When the distance between user A and user B is 5 meters, user A's mobile phone receives the Bluetooth broadcast sent by user B's mobile phone, and calculates the distance as 5 meters based on the signal strength. At this time, it is determined that the distance between user A and user B is greater than the preset Let the straight-line distance be 1 meter; when the distance between user A and user B is less than 1 meter, user A’s mobile phone receives the Bluetooth broadcast sent by user B’s mobile phone, and calculates the distance as 0.9m based on the signal strength, at this time it is judged that user A The distance to user B is less than 1 meter of the preset straight line distance.

Further, in step S300, when the straight-line distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is less than a predetermined distance, a corresponding reminder is given.

In this embodiment, when it is judged that the straight-line distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is less than the preset predetermined distance, both the first Bluetooth mobile terminal and the second Bluetooth mobile terminal are controlled to vibrate and pop up a window Prompt to inform users that the current distance is relatively short and social distance should be controlled.

Specifically, as shown in FIG. 4, step S300 includes:

Step S301 , when the linear distance between the first Bluetooth mobile terminal and the second Bluetooth mobile terminal is less than the predetermined distance, control both the first Bluetooth mobile terminal and the second Bluetooth mobile terminal to vibrate and pop up a window prompt.

For example, when the distance between user A and user B is less than 1 meter, for example, when it is detected that the straight-line distance between the two mobile phones is 0.9m, both user A's mobile phone and user B's mobile phone will vibrate and a pop-up window will prompt the user to control the social distance. In addition to vibration, other customary notification methods for prompting the user, such as ringing a bell, can also be used. When user A's mobile phone and user B's mobile phone turn on the half-duplex Bluetooth function, the sending and receiving broadcasts are carried out alternately. When the two mobile phones turn on the full-duplex Bluetooth function, the sending and receiving broadcasts are carried out simultaneously. When the calculated signal strength and distance between users is less than the preset distance, the user is prompted to control the social distance.

In the second embodiment, to illustrate that the present invention can be used not only in mobile phones, but also in common smart wearable devices such as smart bracelets equipped with Bluetooth functions. When user A and user B are shopping in the supermarket, both user A and user B wear smart wristbands with Bluetooth function, and they both turn on the function of detecting the terminal distance and reminding the user to keep social distance in real time when they go out. Function or application APP, the two smart bracelets adopt full-duplex working mode, and receive broadcast data while sending Bluetooth broadcast containing specific data. The sending frequency can be freely set according to power consumption, such as once every 5s or once every 30s.

When user A is far away from user B, such as 9m, user A's Bluetooth bracelet A cannot receive the Bluetooth broadcast with specific data sent by user B's Bluetooth bracelet B, and Bluetooth bracelet B cannot receive the Bluetooth broadcast of the Bluetooth bracelet. Bluetooth broadcast from Ring A. When user A and user B enter the same store to purchase goods, the distance between the Bluetooth bracelet A and the Bluetooth bracelet B is shortened to 3m, and the Bluetooth bracelet A and the Bluetooth bracelet B begin to receive the information sent by the other party with a specific Bluetooth broadcast data, and through calculation, the distance between Bluetooth bracelet A and Bluetooth bracelet B is 3m, which is not less than the preset reminder distance.

Furthermore, when user A and user B come to the same shelf to select daily necessities, Bluetooth bracelet A and Bluetooth bracelet B detect that the signal strength of the broadcast sent by the other party is getting higher and higher until the distance calculated by the signal strength is less than 1 When the time is 2.5 meters, Bluetooth bracelet A and Bluetooth bracelet B will vibrate at the same time, reminding the user that there are other users who are close to each other and they need to maintain a safe social distance. When user A and user B feel the vibration of the bracelet, the Bluetooth bracelet will no longer vibrate after the two maintain a safe social distance again. When multiple users in the shopping mall wear a Bluetooth bracelet equipped with a mobile terminal distance reminder function, the Bluetooth bracelet obtains multiple Bluetooth broadcasts but only the Bluetooth broadcast with the highest signal strength is used for calculation, which can greatly reduce the data processing and power of the Bluetooth bracelet. consumption.

In order to further improve the freedom of the user when using this function, a user-adjustable function can be added to the corresponding function of the mobile terminal or the application APP. For example, the reminder method can use various reminders such as vibration, continuous vibration, periodic vibration, and ringing. In addition, you can also set the detection frequency and preset distance of Bluetooth broadcasting. The detection frequency ranges from 1 second to 10 minutes, and the preset distance is 0.5m to 10 minutes. between 5m.
