Description

Display screen position identification method, electronic device and computer readable storage medium

Technical Field

The present application belongs to the technical field of electronic devices, and in particular, to a display screen position identification method, an electronic device, and a computer-readable storage medium.

Background

With the development of science and technology, various electronic devices have moved into thousands of households.

Some users have a plurality of electronic devices (e.g., tablet computers, notebook computers, mobile phones, etc.) with display screens. When the user uses the electronic equipment with the display screen, the user can set the main display equipment, the display screens of other electronic equipment are used as the expansion screens of the main display equipment, and the plurality of display screens are matched to display the picture of the main display equipment.

However, in the current screen expansion scheme, the user needs to manually configure the relative position information of each display screen in the configuration information of the main display device so that each display screen displays an appropriate screen. When the relative position between each display screen changes, the user needs to reconfigure the relative position information of each display screen, and the user experience is very poor.

Disclosure of Invention

The embodiment of the application provides a display screen position identification method, electronic equipment and a computer readable storage medium, and can solve the problems that in the existing screen expansion scheme, a user needs to manually set the relative position information of each display screen, the operation is complex, and the user experience is low.

In a first aspect, an embodiment of the present application provides a method for identifying a position of a display screen, where the method is applied to a first device, a display screen of the first device is provided with a first antenna and a second antenna, and the method includes:

when the first antenna receives a first wireless message sent by a third antenna, the first equipment acquires a first received signal strength indication corresponding to the first wireless message, and the third antenna is arranged on a display screen of second equipment;

when the second antenna receives the first wireless message sent by the third antenna, the first device obtains a second received signal strength indication corresponding to the first wireless message;

and the first equipment determines the relative position relationship between the display screen of the first equipment and the display screen of the second equipment according to the first received signal strength indication, the second received signal strength indication and the relative position relationship between the first antenna and the second antenna.

It should be noted that the Received Signal Strength Indication (RSSI) is used to indicate the Signal Strength of the wireless message Received by the antenna. The greater the RSSI is, the higher the signal intensity of the wireless message is; the smaller the RSSI, the lower the signal strength of the wireless message. The RSSI decreases with increasing transmission distance.

A first antenna and a second antenna are separately arranged on a display screen of the first device, and a certain distance exists between the first antenna and the second antenna. Therefore, when the first device receives the first wireless message sent by the second device through the third antenna through the first antenna and the second antenna, because the transmission distances corresponding to the first antenna and the second antenna are different, a certain difference exists between a first received signal strength indicator (i.e., a first RSSI) detected when the first antenna receives the first wireless message and a second received signal strength indicator (i.e., a second RSSI) detected when the second antenna receives the first wireless message.

At this time, the first device may determine the relative positional relationship between the display screen of the first device and the display screen of the second device according to the difference between the first RSSI and the second RSSI and the relative positional relationship between the first antenna and the second antenna.

The first equipment need not user's manual participation at the in-process of the relative position relation of the display screen of discernment first equipment and the display screen of second equipment, easy operation, and it is convenient to use, has improved user's use and has stronger ease for use and practicality.

In a possible implementation manner of the first aspect, after the first device obtains the second received signal strength indication corresponding to the first wireless message, the method further includes:

the first device calculates an absolute value of a difference between the first received signal strength indication and the second received signal strength indication to obtain a first absolute value;

correspondingly, the determining, by the first device, the relative position relationship between the display screen of the first device and the display screen of the second device according to the first received signal strength indication, the second received signal strength indication, and the relative position relationship between the first antenna and the second antenna includes:

if the first absolute value is greater than or equal to a first threshold, the first device determines a relative position relationship between a display screen of the first device and a display screen of the second device according to the first received signal strength indication, the second received signal strength indication and the relative position relationship between the first antenna and the second antenna.

It should be noted that, due to factors such as the antenna layout of the first device and the second device and the fluctuation of the RSSI, in some cases, the first RSSI and the second RSSI may be closer to each other.

Under the condition that the first RSSI and the second RSSI are relatively close to each other, if the first device identifies the relative position relationship between the display screen of the first device and the display screen of the second device according to the first RSSI and the second RSSI, the phenomenon of false identification may occur.

For this, the first device may set the first threshold in advance. After the first device acquires the first RSSI and the second RSSI, calculating an absolute value of a difference value between the first RSSI and the second RSSI to obtain a first absolute value.

And if the first absolute value is greater than or equal to the first threshold, the first device identifies the relative position relationship between the display screen of the first device and the display screen of the second device according to the first RSSI and the second RSSI.

And if the first absolute value is smaller than the first threshold, the first equipment stops recognizing the relative position relation between the display screen of the first equipment and the display screen of the second equipment, so that the phenomenon of false recognition is avoided.

Therefore, the first device sets the first threshold value, so that the first device performs the operation of identifying the relative position relationship between the display screen of the first device and the display screen of the second device under the condition that the difference between the first RSSI and the second RSSI is large, thereby improving the accuracy of position identification.

In a possible implementation manner of the first aspect, the first wireless message includes a second device placement status of the second device;

correspondingly, the determining, by the first device, the relative positional relationship between the display screen of the first device and the display screen of the second device according to the first received signal strength indication, the second received signal strength indication, and the relative positional relationship between the first antenna and the second antenna by the first device includes:

and the first equipment determines the relative position relationship between the display screen of the first equipment and the display screen of the second equipment according to the first received signal strength indication, the second received signal strength indication, the first equipment placing state of the first equipment, the second equipment placing state and the relative position relationship between the first antenna and the second antenna.

It should be noted that, in the process of position identification, the placement state of the first device and the placement state of the second device may affect the result of position identification.

Accordingly, the first device can detect the first device placement state by the first attitude sensor. The second device can detect the second device placement state of the second device through the second attitude sensor, and transmit the second device placement state to the first device through the first wireless message.

In the process of identifying the relative position relationship between the display screen of the first device and the display screen of the second device, the first device additionally considers two factors of the placement state of the first device and the placement state of the second device, so that the accuracy of position identification is further improved.

In a possible implementation manner of the first aspect, the determining, by the first device, a relative positional relationship between a display screen of the first device and a display screen of the second device according to the first received signal strength indication, the second received signal strength indication, and the relative positional relationship between the first antenna and the second antenna by the first device includes:

if the first received signal strength indication is greater than the second received signal strength indication and the first antenna is located on a first side of the second antenna, the first device determines that the display screen of the first device is located on the first side of the display screen of the second device.

It should be noted that one or more matching conditions may be preset in the first device.

After the first device acquires the parameters such as the first RSSI, the second RSSI, and the relative position relationship between the first antenna and the second antenna, the first device may match the acquired parameters with preset matching conditions, so as to determine the relative position relationship between the display screen of the first device and the display screen of the second device.

The preset matching condition can be set according to the actual conditions of the first device and the second device. For example, the preset matching condition may be that if the first RSSI is greater than the second RSSI and the first antenna is located on the first side of the second antenna, the first device determines that the display screen of the first device is located on the first side of the display screen of the second device.

For example, if the first RSSI is greater than the second RSSI and the first antenna is located to the left of the second antenna, the first device may determine that the display screen of the first device is located to the left of the display screen of the second device.

Through the preset matching conditions, the first device can simply and quickly identify the relative position relationship between the display screen of the first device and the display screen of the second device.

In a second aspect, an embodiment of the present application provides a method for identifying a position of a display screen, where the method is applied to a first device, a display screen of the first device is provided with a fourth antenna, and the method includes:

when the fourth antenna receives a second wireless message sent by a fifth antenna, the first device acquires a third received signal strength indication corresponding to the second wireless message;

when the fourth antenna receives a third wireless message sent by a sixth antenna, the first device obtains a fourth received signal strength indication corresponding to the third wireless message, the fifth antenna and the sixth antenna are arranged on a display screen of a second device, and the second wireless message and/or the third wireless message comprise a relative position relationship between the fifth antenna and the sixth antenna;

and the first equipment determines the relative position relationship between the display screen of the first equipment and the display screen of the second equipment according to the third received signal strength indication, the fourth received signal strength indication and the relative position relationship between the fifth antenna and the sixth antenna.

It should be noted that the Received Signal Strength Indication (RSSI) is used for indicating the Signal Strength of the wireless packet Received by the antenna. The greater the RSSI is, the higher the signal intensity of the wireless message is; the smaller the RSSI, the lower the signal strength of the wireless message. The RSSI decreases with increasing transmission distance.

And a fifth antenna and a sixth antenna are separately arranged on the display screen of the second device, and a distance of one point exists between the fifth antenna and the sixth antenna. Therefore, when the first device receives, through the fourth antenna, the second wireless message sent by the second device through the fifth antenna and the third wireless message sent by the second device through the sixth antenna, because the transmission distances corresponding to the fifth antenna and the sixth antenna are different, a certain difference exists between a third received signal strength indicator (i.e., the third RSSI) detected when the fourth antenna receives the second wireless message and a fourth received signal strength indicator (i.e., the fourth RSSI) detected when the fourth antenna receives the third wireless message.

At this time, the first device may determine the relative positional relationship between the display screen of the first device and the display screen of the second device according to a difference between the third RSSI and the fourth RSSI and the relative positional relationship between the fifth antenna and the sixth antenna.

In a possible implementation manner of the second aspect, after the obtaining, by the first device, a fourth received signal strength indication corresponding to the third wireless packet, the method further includes:

the second device calculates an absolute value of a difference between the third received signal strength indication and the fourth received signal strength indication to obtain a second absolute value;

correspondingly, the determining, by the first device, a relative positional relationship between the display screen of the first device and the display screen of the second device according to the third received signal strength indication, the fourth received signal strength indication, and a relative positional relationship between the fifth antenna and the sixth antenna by the first device includes:

if the second absolute value is greater than or equal to a second threshold, the first device determines a relative positional relationship between the display screen of the first device and the display screen of the second device according to the third received signal strength indication, the fourth received signal strength indication, and the relative positional relationship between the fifth antenna and the sixth antenna.

It should be noted that, due to the antenna layouts of the first device and the second device, the fluctuation of the RSSI, and other factors, in some cases, the third RSSI and the fourth RSSI may be closer to each other.

Under the condition that the third RSSI and the fourth RSSI are relatively close, if the first device identifies the relative position relationship between the display screen of the first device and the display screen of the second device according to the third RSSI and the fourth RSSI, the phenomenon of false identification may occur.

For this, the first device may set the second threshold value in advance. And after the first device acquires the third RSSI and the fourth RSSI, calculating an absolute value of a difference value between the third RSSI and the fourth RSSI to obtain a second absolute value.

And if the second absolute value is greater than or equal to the second threshold, the first device identifies the relative position relationship between the display screen of the first device and the display screen of the second device according to the third RSSI and the fourth RSSI.

And if the second absolute value is smaller than the second threshold, the first equipment stops recognizing the relative position relation between the display screen of the first equipment and the display screen of the second equipment, so that the phenomenon of false recognition is avoided.

Therefore, the first device sets the second threshold value, so that the first device performs the operation of identifying the relative position relationship between the display screen of the first device and the display screen of the second device under the condition that the difference between the third RSSI and the fourth RSSI is large, thereby improving the accuracy of position identification.

In a possible implementation manner of the second aspect, the second wireless packet and/or the third wireless packet include a second device placement state of the second device;

and the first device determines the relative position relationship between the display screen of the first device and the display screen of the second device according to the third received signal strength indication, the fourth received signal strength indication, the first device placement state of the first device, the second device placement state and the relative position relationship between the fifth antenna and the sixth antenna.

Accordingly, the first device can detect the first device placement state by the first attitude sensor. The second device may detect a second device placement state of the second device through the second attitude sensor, and transmit the second device placement state to the first device through the second wireless packet and/or the third wireless packet.

In a possible implementation manner of the second aspect, the determining, by the first device, a relative positional relationship between the display screen of the first device and the display screen of the second device according to the third received signal strength indication, the fourth received signal strength indication, and a relative positional relationship between the fifth antenna and the sixth antenna by the first device includes:

if the third rssi is greater than the fourth rssi, and the fifth antenna is located on the first side of the sixth antenna, the first device determines that the display screen of the first device is located on the second side of the display screen of the second device, where the first side and the second side are opposite sides.

After the first device acquires the parameters such as the third RSSI, the fourth RSSI, and the relative position relationship between the fifth antenna and the sixth antenna, the first device may match the acquired parameters with preset matching conditions, so as to determine the relative position relationship between the display screen of the first device and the display screen of the second device.

The preset matching condition can be set according to the actual conditions of the first device and the second device. For example, the preset matching condition may be that if the third RSSI is greater than the fourth RSSI and the fifth antenna is located on the first side of the sixth antenna, the first device determines that the display screen of the first device is located on the second side of the display screen of the second device.

For example, if the third RSSI is greater than the fourth RSSI, and the fifth antenna is located on the left side of the sixth antenna, the first device may determine that the display screen of the first device is located on the right side of the display screen of the second device.

Through presetting the set matching conditions, the first equipment can simply and quickly identify the relative position relationship between the display screen of the first equipment and the display screen of the second equipment.

The system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

For example, a desktop computer of a user is connected with a plurality of display screens, the user can use one of the display screens as a main display screen and use the other display screens as expansion screens, and the plurality of display screens are matched with the display screen output by the desktop computer; for another example, a user may have multiple televisions, which may be spliced into a television wall, and use one of the televisions as a main display device, and display screens of the multiple televisions cooperate to display an on-screen display picture output by the main display device.

In the current screen extension schemes, some screen extension schemes limit the relative position relationship of each display screen, and users can only arrange each display screen according to the set relative position relationship, and the users cannot flexibly set the position of each display screen, so that the user experience is poor.

For example, the hardware screen splitter may divide the screen display into a certain number of parts, and output the parts to different display screens through different output ports (e.g., High Definition Multimedia Interface (HDMI)). The hardware screen splitter pre-defines the arrangement sequence of each display screen, and a user needs to arrange each display screen according to the predefined arrangement sequence of the display screens in the hardware screen splitter.

Other screen expansion schemes require the user to manually configure the relative position information of each display screen in the configuration information of the main display device, so that each display screen can display a proper picture. These screen extension schemes allow a user to flexibly set the position of each display screen, but when the relative position between each display screen changes, the user is required to reconfigure the relative position information of each display screen, which is cumbersome to operate and affects the user experience.

For example, an electronic device (e.g., a laptop or a desktop computer) with a version of macos10.15 or more supports expansion of a tablet computer with a version of iPadOS 13 or more into an expansion screen of the electronic device. But the user needs to manually set the relative position information (e.g., up, down, left, right) between the display screen of the electronic device and the display screen of the tablet computer on the electronic device. When the relative position relationship between the electronic device and the tablet computer changes, the user needs to reset the relative position information between the display screen of the electronic device and the display screen of the tablet computer on the electronic device.

Similarly, when the electronic device equipped with Windows performs screen expansion, the user is also required to manually set the relative position information of each display screen on the electronic device. When the relative position relationship of each display screen changes, the user needs to manually set the relative position information of each display screen again.

Therefore, in the existing screen expansion scheme, a user needs to manually set the relative position information of each display screen, the operation is complicated, and the user experience is low.

In view of this, embodiments of the present application provide a display screen position identification method, an electronic device, and a computer-readable storage medium, which enable the electronic device to automatically identify relative position information of each display screen, and do not need to be manually set by a user, thereby improving user experience, solving the problems of the existing screen extension scheme, requiring the user to manually set the relative position information of each display screen, being cumbersome to operate, and having low user experience, and having strong usability and practicability.

First, taking the display system shown in fig. 1 as an example, the display system is a system to which the display screen position identification method provided in the embodiment of the present application is applied.

As shown in fig. 1, the display system includes at least one first device 1001 and at least one second device 1002, and each of the first device 1001 and the second device 1002 is an electronic device having a display screen.

As shown in fig. 2, the first device 1001 includes a first processor 10011, a first wireless communication module 10012, and an antenna 10013.

As shown in fig. 3, the second device 1002 includes a second processor 10021, a second wireless communication module 10022, and an antenna 10023.

The processor may include one or more processing units, such as: the processor may include an Application Processor (AP), a controller, a memory, and the like. The different processing units may be separate devices or may be integrated into one or more processors.

The wireless communication module includes one or more of Bluetooth (BT), Bluetooth Low Energy (BLE), Wireless Local Area Network (WLAN) (e.g., WiFi), Radio Frequency Identification (RFID), ZigBee (ZigBee), and other wireless communication modules.

At least one antenna 10013 is disposed on the display screen of the first device 1001, and the antenna 10013 is connected to the chip of the first wireless communication module 10012.

At least one antenna 10023 is disposed on the display screen of the second device 1002, and the antenna 10023 is connected to the chip of the second wireless communication module 10022.

The antenna may be configured to send a wireless message modulated by the wireless communication module, or the antenna may also be configured to receive a wireless message sent by another antenna.

The connection between the antenna and the chip of the wireless communication module may be that the antenna is directly connected with the radio frequency output port of the chip, or the antenna is connected with the radio frequency output port of the chip through a radio frequency switch.

For example, as shown in fig. 4, when the number of rf output ports supported by the chip is greater than the number of antennas, the antennas may be directly connected to the rf output ports; as shown in fig. 5, when the number of the rf output ports supported by the chip is less than the number of the antennas, the rf output ports of the chip may be connected to the first end of the rf switch, each antenna may be connected to each second end of the rf switch, and the chip controls the rf switch to dynamically switch the antennas connected to the chip through software.

In addition, the layout mode of the one or more antennas on the display screen can be set according to actual requirements.

For example, as shown in fig. 6, when two antennas are disposed on the display screen, the two antennas may be disposed at diagonal corner points on two sides of the display screen; as shown in fig. 7, when three antennas are disposed on the display screen, the three antennas may be respectively disposed at two corner points and one edge of the display screen; as shown in fig. 8, when four antennas are provided on the display screen, the four antennas may be respectively disposed at four corner points of the display screen.

It should be understood that the above antenna layouts are merely illustrative examples of embodiments of the present application and should not be considered as limitations on the specific antenna layouts. In an actual application process, the electronic device may select the antenna layout in the above example, or the electronic device may select another antenna layout according to an actual requirement.

Hereinafter, the display screen position identification method provided by the embodiment of the present application will be described in detail according to the display systems shown in fig. 1 to 8 and in combination with specific application scenarios.

1. The principle is introduced.

As described above, the antenna may transmit the wireless message modulated by the wireless communication module, or the antenna may receive the wireless message transmitted by another antenna.

When the electronic device receives a wireless message (e.g., a 2.4GHz wireless message, a 5GHz wireless message) through the antenna, the electronic device may detect a Received Signal Strength Indication (RSSI) of the wireless message.

The RSSI is used to indicate the signal strength of the wireless message received by the antenna. The greater the RSSI is, the higher the signal intensity of the wireless message is; the smaller the RSSI, the lower the signal strength of the wireless message.

The RSSI decreases with increasing transmission distance. And the sensitivity of the RSSI along with the change of the transmission distance is inversely proportional to the signal transmission power of the transmitting end of the wireless message, namely the smaller the signal transmission power of the transmitting end is, the greater the sensitivity of the RSSI along with the change of the transmission distance is. The greater the sensitivity of RSSI to changes in transmission distance, the greater the difference in RSSI at the same transmission spacing.

Based on the above phenomenon, the following experiment can be performed:

as shown in fig. 9, in the present experiment, the electronic apparatus 1 and the electronic apparatus 2 were provided. The electronic device 1 is an electronic device that receives wireless messages, and the electronic device 2 is an electronic device that transmits wireless messages. The wireless communication modules arranged on the electronic device 1 and the electronic device 2 are both BLE modules.

An antenna S1 with an operating frequency of 2.4GHz is arranged on the left side of the electronic device 1, an antenna S2 with an operating frequency of 2.4GHz is arranged on the right side of the electronic device 1, and the distance difference between the antenna S1 and the antenna S2 is about 30 cm. An antenna R with an operating frequency of 2.4GHz is provided in the electronic device 2.

In the experiment process, the electronic device 1 controls the antenna S1 and the antenna S2 to receive the wireless message through the BLE module, and the electronic device 2 controls the antenna R to transmit the wireless message through the BLE module.

First, the electronic device 2 controls the antenna R to transmit a wireless message at normal power through the BLE module. At this time, the RSSI 1 of the wireless message transmitted by the antenna R received by the antenna S1 is shown in fig. 10, and the RSSI 2 of the wireless message transmitted by the antenna R received by the antenna S2 is shown in fig. 11.

In fig. 10, the vertical axis represents the RSSI 1 value and the horizontal axis represents the test time T. In fig. 11, the vertical axis represents the RSSI 2 value and the horizontal axis represents the test time T. As can be seen from fig. 10 and 11, when the electronic device 2 controls the antenna R to transmit the wireless message at normal power, the difference between the RSSI 1 and the RSSI 2 detected by the electronic device 1 is not obvious.

Then, the electronic device 2 controls the antenna R to transmit the wireless message in the low power mode through the BLE module. At this time, the RSSI 3 of the wireless message transmitted by the antenna R received by the antenna S1 is shown in fig. 12, and the RSSI 4 of the wireless message transmitted by the antenna R received by the antenna S2 is shown in fig. 13.

In fig. 12, the vertical axis represents the RSSI 3 value, and the horizontal axis represents the test time T. In fig. 13, the vertical axis represents the RSSI 4 value, and the horizontal axis represents the test time T. As can be seen from fig. 12 and 13, when the electronic device 2 controls the antenna R to transmit the wireless message in the low power mode, the RSSI 3 and the RSSI 4 detected by the electronic device 1 have a significant difference, the distance difference between the antenna S1 and the antenna S2 is about 30cm, and the RSSI 3 is reduced by 10-20 dBm compared to the RSSI 4.

In summary, when the electronic device 2 transmits the wireless message in the low power mode, if the electronic device 1 is located at one side of the electronic device 2, the two antennas of the electronic device 1 detect that the RSSI has a difference of 10-20 dBm. Therefore, the electronic device 1 may identify the relative position relationship between the electronic device 1 and the electronic device 2 according to the RSSI of the wireless message detected by the different antennas, or the electronic device 1 may also identify the relative position relationship between the electronic device 1 and the electronic device 2 according to the RSSI of the different wireless message detected by the same antenna.

2. The application is specific.

When the first device 1001 and the second device 1002 have wireless communication functions turned on, the first wireless communication module 10012 of the first device 1001 and the second wireless communication module 10022 of the second device 1002 may discover and connect with each other.

The first device 1001 and the second device 1002 may discover and connect with each other by using wireless solutions such as bluetooth, BLE, WiFi, RFID, or ZigBee, or the first device 1001 and the second device 1002 may discover and connect with each other by using a vendor-defined discovery connection technology.

The first device 1001 and the second device 1002 can transmit and receive wireless messages through the above-described connection. In this embodiment, the first device 1001 may be configured as an electronic device that receives wireless messages, and the second device 1002 may be configured as an electronic device that transmits wireless messages.

After the first device 1001 and the second device 1002 discover and connect with each other, the first device 1001 and the second device 1002 may enter a location recognition mode in which a relative positional relationship of a display screen of the first device 1001 and a display screen of the second device 1002 is recognized.

The first device 1001 and the second device 1002 may automatically trigger the location recognition mode after being connected, or the first device 1001 and the second device 1002 may enter the location recognition mode in response to a physical key operation or a gesture operation of the electronic device by a user.

2.1, the antenna 10013 of the first device 1001 includes at least one first antenna and at least one second antenna, and the antenna 10023 of the second device 1002 includes at least one third antenna.

After entering the location identification mode, the second device 1002 may broadcast the first wireless packet to the outside at a preset power through the third antenna. The first wireless message may include a device identification of the second device 1002 and an antenna identification of the third antenna.

The specific value of the preset power can be set according to actual conditions. Specifically, the preset power should be smaller than a specific power threshold, so that the RSSI of the first wireless packet has a higher sensitivity to a change in transmission distance.

The form of the device identifier can be set according to actual conditions. For example, in some embodiments, a bluetooth address of the electronic device may be used as the device identification. In other embodiments, the user-defined character string may be used as a device identifier of the electronic device. In other embodiments, the device identification may be represented in other forms.

The antenna identification can be set according to actual conditions. For example, in some embodiments, the antenna markers may be represented numerically, such as 001, 002, 003. In other embodiments, the antenna identification may be represented by an English letter, such as A, B, C. In other embodiments, the antenna identification may be represented in other forms.

The device identifier of the second device 1002 and the setting position of the antenna identifier of the third antenna may be selected according to actual situations. For example, when the first wireless packet is a BLE packet, the device identifier of the second device 1002 and the antenna identifier of the third antenna may be set in a secondary field (Minor field) of the BLE packet.

The other electronic devices can determine the transmitting party and the transmitting antenna of the wireless message through the device identifier and the antenna identifier in the wireless message.

The first device 1001 is provided with a first antenna and a second antenna separately. The first device 1001 may periodically listen to the wireless packet on the broadcast channel through the first antenna and the second antenna, or the first device 1001 may continuously detect the wireless packet on the broadcast channel through the first antenna and the second antenna.

When the first device 1001 receives a first wireless message sent by a third antenna through the first antenna, the first device 1001 may obtain a first RSSI corresponding to the first wireless message.

When the first device 1001 receives a first wireless message sent by the third antenna through the second antenna, the first device 1001 may obtain a second RSSI corresponding to the first wireless message.

The RSSI acquired by the first device 1001 may be an instantaneous value of the RSSI, or the RSSI acquired by the first device 1001 may also be an average value of the RSSI over a period of time.

For example, when the first antenna receives the first wireless message, the first device 1001 may use an RSSI instantaneous value of the first wireless message first received by the first antenna as the first RSSI; or, when the first device 1001 receives the first wireless message at the first antenna, it may acquire an RSSI instantaneous value corresponding to each first wireless message received by the first antenna within a preset time period, and then process each RSSI instantaneous value through a moving average algorithm to obtain the first RSSI.

The preset duration can be set according to actual requirements. For example, the preset time period may be set to a value of 10ms, 20ms, 40ms, or the like.

Since the first antenna and the second antenna are disposed at different positions, there may be a difference between the first RSSI and the second RSSI.

At this time, the first device 1001 may determine the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the first RSSI, the second RSSI, and the relative positional relationship between the first antenna and the second antenna.

For example, assuming that the first antenna is located on the first side of the second antenna and the first RSSI is greater than the second RSSI, the first device 1001 may determine that the display screen of the second device 1002 is located on the first side of the display screen of the first device 1001; assuming that the first antenna is located on a first side of the second antenna and the first RSSI is less than the second RSSI, the first device 1001 may determine that the display screen of the second device 1002 is located on a second side of the display screen of the first device 1001.

Specifically, the above-mentioned first side and second side denote opposite sides. For example, when the first side is the left side, the second side is the right side; when the first side is an upper side, the second side is a lower side.

The specific indication directions of the first side and the second side should be set according to actual conditions. For example, in some embodiments, the first side may be any one of up, down, left, and right. In other embodiments, the first side may be any one of upper left, lower left, upper right, and lower right. The present embodiment does not limit the specific indication directions of the first side and the second side.

In addition, since there is a difference in antenna layouts of the respective electronic devices and there is fluctuation in the RSSI measurement process, the first device 1001 may set the first threshold value.

After acquiring the first RSSI and the second RSSI, the first device 1001 may calculate an absolute value of a difference between the first RSSI and the second RSSI to obtain a first absolute value, and determine whether the first absolute value is greater than or equal to a first threshold.

If the first absolute value is smaller than the first threshold, it indicates that the difference between the first RSSI and the second RSSI is small, and at this time, if the first device 1001 identifies the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the first RSSI and the second RSSI, the first device 1001 may cause an identification error due to the fluctuation of the RSSI and the like. Therefore, the first device 1001 can stop recognizing the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002, and determine that the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 cannot be recognized.

If the first absolute value is greater than or equal to the first threshold, the first device 1001 determines the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the first RSSI, the second RSSI, and the relative positional relationship between the first antenna and the second antenna.

The first threshold value may be set according to actual conditions. For example, the first threshold may be set to a value of 3dBm, 5dBm, 10dBm, or the like.

In addition, the placement state of the first device 1001 and the placement state of the second device 1002 may have an influence on the position recognition result (i.e., the relative positional relationship between the display screen of the first antenna and the display screen of the second antenna).

Accordingly, the first device 1001 may determine the first device placement state from sensor data collected by the first attitude sensor, and the second device 1002 may determine the second device placement state from sensor data collected by the second attitude sensor.

The first attitude sensor is provided on the display screen of the first device 1001, and the second attitude sensor is provided on the display screen of the second device 1002.

The above-mentioned placing state may include a forward state and an upside-down state. The electronic device may define a placement state of a certain direction as a forward state. The inverted state is a placement state opposite to the forward state, and generally, the inverted state can be understood as a placement state that the electronic device is assumed after being vertically rotated by 180 ° or horizontally rotated by 180 ° in the forward state.

After acquiring the placement state of the second device, the second device 1002 may transmit the placement state of the second device to the first device 1001 through the first wireless packet.

After the first device 1001 acquires the first device placement state and the second device placement state, the first device 1001 may determine a relative position relationship between a display screen of the first device 1001 and a display screen of the second device 1002 according to the first RSSI, the second RSSI, the first device placement state, the second device placement state, and the relative position relationship between the first antenna and the second antenna.

For example, assume that when the first device 1001 is in the forward state, the first antenna is located on a first side of the second antenna, and the first RSSI is greater than the second RSSI. At this time, if the first device placement state is a forward state and the second device placement state is a forward state, the first device 1001 may determine that the display screen of the second device 1002 is located on the first side of the display screen of the first device 1001; if the first device placement state is an inverted state and the second device placement state is a forward state, the first device 1001 may determine that the display screen of the first device 1001 is located on the first side of the display screen of the second device 1002.

The attitude sensor is used for detecting the placing state of the electrons. The attitude sensor may include one or more of a gyroscope, an accelerometer, an electronic compass, and the like.

The method for identifying the position of the display screen described in section 2.1 will be explained with reference to a specific application scenario.

The application scene one:

as shown in fig. 14, it is assumed that the first device 1001 is the tablet pc 11 and the second device 1002 is the tablet pc 12. An antenna 13 and an antenna 14 are respectively arranged at diagonal corner points of the display screen of the tablet computer 11, the antenna 13 is located on the left side of the antenna 14, and an antenna 15 is arranged on one edge of the display screen of the tablet computer 12.

When the tablet computer 11 and the tablet computer 12 enter the location recognition mode, the tablet computer 12 broadcasts a first wireless message through the antenna 15, where the first wireless message includes the device identifier of the tablet computer 12 and the antenna identifier of the antenna 15.

When the tablet computer 11 receives the first wireless message through the antenna 13, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 12 through the antenna 15.

At this time, the tablet computer 11 records the RSSI corresponding to each first wireless message received by the antenna 13 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 1.1.

When the tablet computer 11 receives the first wireless message through the antenna 14, it is determined through the device identifier and the antenna identifier in the first wireless message that the tablet computer 12 sends the first wireless message through the antenna 15.

At this time, the tablet computer 11 records the RSSI corresponding to each first wireless message received by the antenna 14 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 1.2.

By comparison, RSSI 1.1 is less than RSSI 1.2, and antenna 13 is located on the left side of antenna 14, so tablet 11 can determine that tablet 12 is located on the right side of tablet 11.

Application scenario two:

as shown in fig. 15, it is assumed that the first device 1001 is a tablet computer 21 and the second device 1002 is a tablet computer 22. An antenna 23 and an antenna 24 are respectively arranged at diagonal corner points of the display screen of the tablet computer 21, the antenna 23 is positioned at the left side of the antenna 24, and an antenna 25 is arranged on one edge of the display screen of the tablet computer 22.

When the tablet computer 21 and the tablet computer 22 enter the location recognition mode, the tablet computer 22 broadcasts a first wireless message through the antenna 25, where the first wireless message includes the device identifier of the tablet computer 22 and the antenna identifier of the antenna 25.

When the tablet computer 21 receives the first wireless message through the antenna 23, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 22 through the antenna 25.

At this time, the tablet computer 21 records the RSSI corresponding to each first wireless message received by the antenna 23 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 2.1.

When the tablet computer 21 receives the first wireless message through the antenna 24, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 22 through the antenna 25.

At this time, the tablet computer 21 records the RSSI corresponding to each first wireless message received by the antenna 24 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 2.2.

By comparison, RSSI 2.1 is greater than RSSI 2.2, and antenna 23 is located on the left side of antenna 24, so tablet 21 can determine that tablet 22 is located on the left side of tablet 21.

Application scenario three:

as shown in fig. 16, it is assumed that the first device 1001 is the tablet pc 31 and the second device 1002 is the tablet pc 32. An antenna 33 and an antenna 34 are respectively arranged at diagonal corner points of the display screen of the tablet computer 31, the antenna 33 is positioned at the lower side of the antenna 34, and an antenna 35 is arranged on one edge of the display screen of the tablet computer 32.

When the tablet computer 31 and the tablet computer 32 enter the location recognition mode, the tablet computer 32 broadcasts a first wireless message through the antenna 35, where the first wireless message includes a device identifier of the tablet computer 32 and an antenna identifier of the antenna 35.

When the tablet computer 31 receives the first wireless message through the antenna 33, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 32 through the antenna 35.

At this time, the tablet computer 31 records the RSSI corresponding to each first wireless message received by the antenna 33 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 3.1.

When the tablet computer 31 receives the first wireless message through the antenna 34, it is determined that the first wireless message is sent by the tablet computer 32 through the antenna 35 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet computer 31 records the RSSI corresponding to each first wireless message received by the antenna 34 within the preset time period, and calculates an average value of the RSSI to obtain the RSSI 3.2.

By comparison, RSSI 3.1 is greater than RSSI 3.2, and antenna 33 is located under antenna 34, so tablet 31 can determine that tablet 32 is located under tablet 31.

The application scene four is as follows:

as shown in fig. 17, assume that the first device 1001 is a tablet pc 41 and the second device 1002 is a tablet pc 42. An antenna 43 and an antenna 44 are respectively arranged at diagonal corner points of the display screen of the tablet computer 41, the antenna 43 is located on the left side of the antenna 44, and an antenna 45 is arranged on one edge of the display screen of the tablet computer 42.

When the tablet computers 41 and 42 enter the location recognition mode, the tablet computer 42 broadcasts a first wireless message through the antenna 45, where the first wireless message includes the device identifier of the tablet computer 42 and the antenna identifier of the antenna 45.

When the tablet 41 receives the first wireless message through the antenna 43, it is determined that the first wireless message is sent by the tablet 42 through the antenna 45 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet 41 records the RSSI corresponding to each first wireless message received by the antenna 43 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 4.1.

When the tablet 41 receives the first wireless message through the antenna 44, it is determined that the first wireless message is sent by the tablet 42 through the antenna 45 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet 41 records the RSSI corresponding to each first wireless message received by the antenna 44 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 4.2.

By comparison, RSSI 4.1 is greater than RSSI 4.2, the absolute value of the difference between RSSI 4.1 and RSSI 4.2 is greater than the first threshold, and the antenna 43 is located on the left side of the antenna 44, so the tablet 41 can determine that the tablet 42 is located on the left side of the tablet 41.

Application scenario five:

as shown in fig. 18, it is assumed that the first device 1001 is the tablet pc 51 and the second device 1002 is the tablet pc 52. An antenna 53 and an antenna 54 are arranged on the display screen of the tablet computer 51, the antenna 53 is positioned on the left side of the antenna 54, and an antenna 55 is arranged on one side of the display screen of the tablet computer 52.

When the tablet pc 51 and the tablet pc 52 enter the location recognition mode, the tablet pc 52 broadcasts a first wireless message through the antenna 55, where the first wireless message includes the device identifier of the tablet pc 52 and the antenna identifier of the antenna 55.

When the tablet computer 51 receives the first wireless message through the antenna 53, it is determined that the first wireless message is sent by the tablet computer 52 through the antenna 55 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet computer 51 records the RSSI corresponding to each first wireless message received by the antenna 53 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 5.1.

When the tablet computer 51 receives the first wireless message through the antenna 54, it is determined that the first wireless message is sent by the tablet computer 52 through the antenna 55 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet computer 51 records the RSSI corresponding to each first wireless message received by the antenna 54 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 5.2.

Through comparison, the RSSI 5.1 is greater than the RSSI 5.2, but the absolute value of the difference between the RSSI 5.1 and the RSSI 5.2 is smaller than the first threshold, so the tablet computer 51 stops recognizing the relative position relationship between the tablet computer 51 and the tablet computer 52, and the tablet computer 51 determines that the relative position relationship between the tablet computer 51 and the tablet computer 52 cannot be recognized.

Application scenario six:

as shown in fig. 19, it is assumed that the first device 1001 is the tablet computer 61 and the second device 1002 is the tablet computer 62. An antenna 63 and an antenna 64 are respectively arranged at diagonal corner points of the display screen of the tablet computer 61, and when the placement state of the tablet computer 61 is a forward state, the antenna 63 is located on the left side of the antenna 64. An antenna 65 is provided on one side of the display screen of the tablet computer 62.

When the tablet computer 61 and the tablet computer 62 enter the position recognition mode, the tablet computer 62 broadcasts a first wireless message through the antenna 65, the first wireless message includes the device identifier of the tablet computer 62, the antenna identifier of the antenna 65, and the second device placement state is a forward state.

When the tablet computer 61 receives the first wireless message through the antenna 63, it is determined that the first wireless message is sent by the tablet computer 62 through the antenna 65 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet computer 61 records the RSSI corresponding to each first wireless message received by the antenna 63 within the preset time period, and calculates an average value of the RSSI to obtain the RSSI 6.1.

When the tablet computer 61 receives the first wireless message through the antenna 64, it is determined that the first wireless message is sent by the tablet computer 62 through the antenna 65 according to the device identifier and the antenna identifier in the first wireless message.

At this time, the tablet computer 61 records the RSSI corresponding to each first wireless message received by the antenna 64 within the preset time period, and calculates an average value of each RSSI to obtain the RSSI 6.2.

Through comparison, the RSSI 6.1 is greater than the RSSI 6.2, the absolute value of the difference between the RSSI 6.1 and the RSSI 6.2 is greater than the first threshold, the gyroscope of the tablet computer 61 detects that the tablet computer 61 is in the inverted state, the second device placement state is in the forward state, and when the tablet computer 61 is in the forward state, the antenna 63 is located on the left side of the antenna 64, so that the tablet computer 61 can determine that the tablet computer 61 is located on the left side of the tablet computer 62.

It should be understood that although only one first antenna, one second antenna, and one third antenna are shown in the above examples. However, in practical applications, there may be one or more first antennas, one or more second antennas, and one or more third antennas for the first device 1001 and the second device 1002.

At this time, the first device 1001 may select an appropriate first antenna and second antenna to construct a first antenna combination to implement the above-described display screen position identification method.

For example, assuming that the first antenna includes antenna a and antenna B, and the second antenna includes antenna C, the first device 1001 may constitute a combination of the two first antennas [ antenna a, antenna C ], [ antenna B, antenna C ].

When there are a plurality of first antenna combinations or a plurality of third antennas, the first device 1001 can obtain a plurality of position recognition results. At this time, the first device 1001 may determine the target position recognition result according to a preset rule and the plurality of position recognition results.

The specific content of the preset rule can be set according to actual conditions.

In some possible implementations, the preset rule may be: if the respective position recognition results are consistent, the first device 1001 takes the position recognition result as a target position recognition result; if the respective position recognition results do not coincide, the first device 1001 stops recognizing the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002, and the first device 1001 determines that the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 cannot be recognized.

For example, assume that the first device 1001 detects 5 position recognition results. If the 5 position recognition results are that the display screen of the first device 1001 is on the left side of the display screen of the second device 1002, the first device 1001 determines that the display screen of the first device 1001 is on the left side of the display screen of the second device 1002. If there are 3 position recognition results among the 5 position recognition results that the display screen of the first device 1001 is on the left side of the display screen of the

second device

1002 and 2 position recognition results that the display screen of the first device 1001 is on the right side of the display screen of the second device 1002, the first device 1001 stops recognizing the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002, and the first device 1001 determines that the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 cannot be recognized.

In other possible implementations, the preset rule may be: the first device 1001 selects the position recognition result that appears the highest frequency among the respective position recognition results.

For example, assume that the first device 1001 detects 5 position recognition results. If there are 3 position recognition results that the display screen of the first device 1001 is on the left side of the display screen of the

second device

1002, 1 position recognition result that the display screen of the first device 1001 is on the right side of the display screen of the

second device

1002, and 1 position recognition result that the display screen of the first device 1001 is not recognizable, the first device 1001 determines that the display screen of the first device 1001 is on the left side of the display screen of the second device 1002.

In other possible implementations, the preset rule may be set as another rule according to actual situations.

An application scene seven:

as shown in fig. 20, it is assumed that the first device 1001 is the tablet pc 71 and the second device 1002 is the tablet pc 72. Three corner points of the display screen of the tablet computer 71 are respectively provided with an antenna 73, an antenna 74 and an antenna 75. Antenna 73 is a first antenna and antennas 74 and 75 are second antennas. The antenna 74 and the antenna 75 are both located on the upper side of the antenna 73. An antenna 76 is provided on one side of the display screen of the tablet computer 72.

At this time, the tablet 71 may determine two first antenna combinations [ antenna 73, antenna 74] and [ antenna 73, antenna 75 ].

When the tablet computer 71 and the tablet computer 72 enter the location recognition mode, the tablet computer 72 broadcasts a first wireless message through the antenna 76, wherein the first wireless message includes the device identifier of the tablet computer 72 and the antenna identifier of the antenna 76.

When the tablet computer 71 receives the first wireless message through the antenna 73, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 72 through the antenna 76.

At this time, the tablet pc 71 records the RSSI corresponding to each first wireless message received by the antenna 73 within the preset time period, and calculates an average value of the RSSI to obtain the RSSI 7.1.

When the tablet computer 71 receives the first wireless message through the antenna 74, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 72 through the antenna 76.

At this time, the tablet computer 71 records the RSSI corresponding to each first wireless message received by the antenna 74 within the preset time period, and calculates an average value of each RSSI to obtain an RSSI of 7.2.

When the tablet computer 71 receives the first wireless message through the antenna 75, it is determined through the device identifier and the antenna identifier in the first wireless message that the first wireless message is sent by the tablet computer 72 through the antenna 76.

At this time, the tablet computer 71 records the RSSI corresponding to each first wireless message received by the antenna 75 within the preset time period, and calculates an average value of the RSSI to obtain the RSSI 7.3.

By comparison, RSSI 7.1 is smaller than RSSI 7.2, the absolute value of the difference between RSSI 7.1 and RSSI 7.2 is larger than the first threshold, and the antenna 73 is located at the lower side of the antenna 74, so the tablet computer 72 is located at the upper side of the tablet computer 71 as the position identification result determined by the tablet computer 71 based on the antenna 73 and the antenna 74.

RSSI 7.1 is smaller than RSSI 7.3, but the absolute value of the difference between RSSI 7.1 and RSSI 7.3 is smaller than the first threshold, so the tablet computer 71 cannot identify the relative position relationship between the tablet computer 71 and the tablet computer 72 based on the position identification result determined by antenna 73 and antenna 75.

At this time, the tablet pc 71 combines the two position recognition results, and determines that the tablet pc 72 is located on the upper side of the tablet pc 71.

In summary, in the display screen location identification method provided in the embodiment, the first device 1001 may determine the relative location relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the first RSSI of the first wireless packet received by the first antenna, the second RSSI of the second wireless packet received by the second antenna, and the relative location relationship between the first antenna and the second antenna, and a user does not need to actively configure the relative location information between the display screen of the first device 1001 and the display screen of the second device 1002.

In addition, the first device 1001 may further set a first threshold, and when the absolute value of the difference between the first RSSI and the second RSSI is greater than or equal to the first threshold, the first device 1001 identifies the relative position relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the first RSSI and the second RSSI, thereby improving the accuracy of position identification.

In addition, in order to avoid that the first device 1001 misjudges the position recognition result due to the placement state of the first device 1001 and the placement state of the second device 1002 in the position recognition process, the first device 1001 may recognize the placement state of the first device through sensor data collected by the first attitude sensor, and the second device 1002 may recognize the placement state of the second device through sensor data collected by the second attitude sensor, and transmit the second device to the first device 1001 through the first wireless message, so that the first device 1001 may determine the position recognition result by combining the placement state of the first device and the placement state of the second device, and the accuracy of the position recognition is further improved.

When the first device 1001 is provided with a plurality of first antenna combinations or the second device 1002 is provided with a plurality of third antenna combinations, the first device 1001 may obtain a plurality of position recognition results, and may obtain a final target position recognition result according to a preset rule and the plurality of position recognition results. The first device 1001 determines the target position recognition result by integrating the plurality of position recognition results, and can more accurately recognize the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002.

2.2, the antenna of the first device 1001 includes at least one fourth antenna, and the antenna of the second device 1002 includes at least one fifth antenna and at least one sixth antenna.

After entering the location identification mode, the second device 1002 may broadcast the second wireless packet at a preset power via the fifth antenna, and broadcast the third wireless packet at a preset power via the sixth antenna.

The specific value of the preset power can be set according to actual conditions. Specifically, the preset power should be smaller than a specific power threshold, so that the RSSI of the second wireless packet and the RSSI of the third wireless packet have higher sensitivity to the change of the transmission distance.

The second wireless message may include the device identification of second device 1002 and the antenna identification of the fifth antenna. The third wireless message may include the device identification of second device 1002 and the antenna identification of the sixth antenna. And, the second wireless message and/or the third wireless message may include a relative position relationship of the fifth antenna and the sixth antenna.

The relative position of the fifth antenna and the sixth antenna can be represented by a preset relative position mark. The first device 1001 and the second device 1002 may set in advance an association relationship of a relative positional relationship and a relative positional identification. After the first device 1001 acquires the relative position identifier, the relative position relationship between the fifth antenna and the sixth antenna may be determined according to the association relationship between the relative position relationship and the relative position identifier.

For example, the first device 1001 and the second device 1002 may be previously set to "00" indicating that the fifth antenna is on the upper side of the sixth antenna, "01" indicating that the fifth antenna is on the lower side of the sixth antenna, "10" indicating that the fifth antenna is on the left side of the sixth antenna, and "11" indicating that the fifth antenna is on the right side of the sixth antenna. When the second wireless message received by the first device 1001 includes the relative location identifier "10", the first device 1001 may determine that the fifth antenna is on the left side of the sixth antenna according to the relative location identifier "10".

The setting positions of the device identifier of the second device 1002, the antenna identifier of the fifth antenna, the antenna identifier of the sixth antenna, and the relative position identifier may be selected according to actual situations. For example, when the first wireless packet is a BLE packet, the device identifier of the second device 1002, the antenna identifier of the fifth antenna, the antenna identifier of the sixth antenna, and the relative location identifier may be set in a Minor field of the BLE packet.

The first device 1001 may periodically listen for wireless messages on the broadcast channel through the fourth antenna, or the first device 1001 may continuously listen for wireless messages on the broadcast channel through the fourth antenna.

When the first device 1001 receives the second wireless packet sent by the fifth antenna through the fourth antenna, the first device 1001 may obtain a third RSSI corresponding to the second wireless packet.

When the first device 1001 receives, through the fourth antenna, the third wireless packet sent by the sixth antenna, the first device 1001 may obtain a fourth RSSI corresponding to the third wireless packet.

For example, when the first device 1001 receives the second wireless packet at the fourth antenna, the RSSI instantaneous value of the second wireless packet first received at the fourth antenna may be used as the third RSSI; or, when the first device 1001 receives the second wireless message at the fourth antenna, it may acquire an RSSI instantaneous value corresponding to each second wireless message received by the fourth antenna within a preset time period, and then process each RSSI instantaneous value through a moving average algorithm to obtain a third RSSI.

Since the fifth antenna and the sixth antenna are disposed at different positions, there may be a difference between the third RSSI and the fourth RSSI.

At this time, the first device 1001 may determine the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the third RSSI, the fourth RSSI, and the relative positional relationship between the fifth antenna and the sixth antenna.

For example, assuming that the fifth antenna is located on the first side of the sixth antenna and the third RSSI is greater than the fourth RSSI, the first device 1001 may determine that the display screen of the first device 1001 is located on the first side of the display screen of the second device 1002; assuming that the fifth antenna is located on the first side of the sixth antenna and the third RSSI is less than the fourth RSSI, the first device 1001 may determine that the display screen of the first device 1001 is located on the second side of the display screen of the second device 1002.

Also, the first device 1001 may set the second threshold value because there is a difference in antenna layout of each electronic device and there is fluctuation in the RSSI measurement process.

After acquiring the third RSSI and the fourth RSSI, the first device 1001 may calculate an absolute value of a difference between the third RSSI and the fourth RSSI to obtain a second absolute value, and determine whether the second absolute value is greater than or equal to a second threshold.

If the second absolute value is less than the second threshold, it indicates that the difference between the third RSSI and the fourth RSSI is small. At this time, if the first device 1001 identifies the relative positional relationship of the display screen of the first device 1001 and the display screen of the second device 1002 from the third RSSI and the fourth RSSI, the first device 1001 may cause an identification error due to the fluctuation of the RSSI and the like. Therefore, the first device 1001 can stop recognizing the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002, and determine that the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 cannot be recognized.

If the second absolute value is greater than or equal to the second threshold, the first device 1001 determines the relative positional relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the third RSSI, the fourth RSSI, and the relative positional relationship between the first antenna and the second antenna.

The second threshold value may be set according to actual conditions. For example, the second threshold may be set to a value of 3dBm, 5dBm, 10dBm, or the like.

Thus, the first device 1001 may determine a first device placement state from sensor data collected by the first attitude sensor, and the second device 1002 may determine a second device placement state from sensor data collected by the second attitude sensor.

After acquiring the placement state of the second device, the second device 1002 may transmit the placement state of the second device to the first device 1001 through the second wireless packet and/or the third wireless packet.

After the first device 1001 acquires the first device placement state and the second device placement state, the first device 1001 may determine the relative position relationship between the display screen of the first device 1001 and the display screen of the second device 1002 according to the third RSSI, the fourth RSSI, the first device placement state, the second device placement state, and the relative position relationship between the fifth antenna and the sixth antenna.

For example, assume that when the first device 1001 is in the forward state, the fifth antenna is located on the first side of the sixth antenna, and the third RSSI is greater than the fourth RSSI. At this time, if the first device placement state is a forward state and the second device placement state is a forward state, the first device 1001 may determine that the display screen of the second device 1002 is located on the second side of the display screen of the first device 1001; if the first device placement state is a forward state and the second device placement state is an inverted state, the first device 1001 may determine that the display screen of the second device 1002 is located on a first side of the display screen of the first device 1001.

Also, there may be one or more fourth antennas, one or more fifth antennas, and one or more sixth antennas for the first device 1001 and the second device 1002.

At this time, the second device 1002 may select an appropriate fifth antenna and an appropriate sixth antenna to construct the second antenna combination to implement the above-described display screen position identification method.

For example, assuming that the fifth antenna includes antenna D and antenna E, and the sixth antenna includes antenna F, the second device 1002 may construct a combination of two second antennas [ antenna D, antenna F ], [ antenna E, antenna F ].

When the first device 1001 has a plurality of fourth antennas or the second device 1002 has a plurality of second antennas combined, the first device 1001 can obtain a plurality of position recognition results. At this time, the first device 1001 may determine the target position recognition result according to a preset rule and the plurality of position recognition results.

The preset rule may be formulated as described in section 2.1, which is not repeated herein.

The method for identifying the position of the display screen described in section 2.2 will be explained with reference to a specific application scenario.

The tablet 82 broadcasts a third wireless message via the antenna 85, where the third wireless message includes the device identifier of the tablet 82 and the antenna identifier of the antenna 85.

And, the second wireless message and/or the third wireless message includes the relative location identification of the antenna 84 and the antenna 85.
