Data sharing method and related device

Technical Field

The present application relates to the field of short-distance communications, and in particular, to a data sharing method and related apparatus.

Background

With the development of wireless communication technology, electronic devices such as smart phones and tablet computers start supporting users to share file data such as pictures, documents and videos to other devices, and therefore the office efficiency and the office experience of the users are improved. For example, a user may share file data such as pictures, documents, and videos on an electronic device such as a smartphone to other devices without using a data line.

At present, when a user wants to share file data such as pictures on electronic equipment such as a smart phone to other equipment, the user needs to manually select the file data to be sent, then open a Wi-Fi function, and search surrounding equipment with the Wi-Fi function opened. Then, the user needs to select the receiving device in the search device list to perform file transmission, which makes the user operation complicated.

In order to solve the above problems, two existing electronic devices with Near Field Communication (NFC) functions may implement Wi-Fi automatic connection and wireless data transmission through NFC sensing area contact. According to the technology, automatic data wireless transmission between the devices can be realized only by the NFC function of the two devices, if one device does not have the NFC function, the function cannot be realized, and therefore, the data cannot be rapidly shared for other devices for the electronic devices without the support of NFC hardware.

The memory 202 may store an operating system, such as an embedded operating system like uCOS, vxWorks, RTLinux, etc. Memory 202 may also store communication programs that may be used to communicate with electronic device 100, or other devices.

The wireless communication module 203 may include one or more of a bluetooth communication module 203A, WLAN communication module 203B. It is possible that the bluetooth communication module 203A may be integrated with other communication modules (e.g., the WLAN communication module 203B).

In some embodiments, one or more of the bluetooth communication modules 203A, WLAN and the communication module 203B may listen to signals, such as measurement signals, scanning signals, and the like, transmitted by other devices (such as the electronic device 100) and may send response signals, such as measurement responses, scanning responses, and the like, so that the other devices (such as the electronic device 100) may discover the electronic device 200 and establish wireless communication connections with the other devices (such as the electronic device 100) through one or more of bluetooth, WLAN, or other short-range wireless communication technologies for data transmission.

In other embodiments, one or more of the bluetooth communication modules 203A, WLAN and the communication module 203B may also transmit signals, such as broadcast probe signals and beacon signals, so that other devices (e.g., the electronic device 100) may discover the electronic device 200 and establish a wireless communication connection with other devices (e.g., the electronic device 100) via one or more of bluetooth and WLAN or other short-range wireless communication technologies for data transmission.

Antenna 204 may be used to transmit and receive electromagnetic wave signals. The antennas of different communication modules can be multiplexed and can also be mutually independent so as to improve the utilization rate of the antennas. For example: the antenna of the bluetooth communication module 203A may be multiplexed as the antenna of the WLAN communication module 203B.

The display screen 205 may be used to display images, video, and the like. The display screen 194 includes a display panel.

Visual output associated with the touch operation may be provided through the display screen 205. In other embodiments, the touch sensor may be located on a different surface of the electronic device 200 than the display screen 205.

The power management module 206 may be used to control the power of the power supply to the electronic device 200.

The audio module 207 is operable to output audio signals through the audio output interface, which enables the electronic device 200 to support audio playback. The audio module 207 may also be used to receive audio data through an audio input interface. When the voice wake-up function of the electronic device 200 is turned on, the audio module 207 may collect ambient sound in real time to obtain audio data.

The millimeter wave radar module 208 may be configured to transmit an electromagnetic wave through the transmitting antenna 1 and receive an electromagnetic wave (i.e., an echo signal) reflected from the obstruction through at least one receiving antenna (e.g., the receiving antenna 1, the receiving antenna 2, and the receiving antenna 3). The millimeter wave radar module 208 measures distance, speed and direction of the shelter by sending and receiving parameters of electromagnetic waves. The millimeter wave radar module 208 can measure the distance, the speed, and the direction of a plurality of obstacles simultaneously through the outlines of the obstacles, and also can measure one or more of the distance, the speed, and the direction of the obstacles. The millimeter wave radar module 208 may measure the distance to the obstruction by the time difference between the transmission and reception of the electromagnetic wave. The millimeter wave radar module 208 may measure the speed of the obstruction by transmitting and receiving the doppler effect of the electromagnetic waves. The millimeter wave radar chip 208 can calculate the azimuth angle (including the horizontal angle and the vertical angle) of the shelter by the phase difference of the electromagnetic waves reflected by the same shelter and received by two or more receiving antennas. Wherein, the more receiving antennas, the more accurate the measurement result of the shielding object by the millimeter wave radar module 208.

The frequency band of the millimeter wave radar module 208 for emitting the electromagnetic wave through the transmitting antenna 1 may include 24GHz, 60GHz, 77GHz, 120GHz, and the like. The higher the frequency band is, the longer the effective detection distance of the millimeter wave radar module 208 to the obstruction is. Millimeter wave radar module 208 has certain detection area, and when the shelter was located the detection area, millimeter wave radar module 208 can receive the millimeter wave signal that the shelter reflected, and when the shelter was located outside the detection area, millimeter wave radar module 208 can't receive the millimeter wave signal that the shelter reflected. Thus, when the obstruction is movable within the detection area within which the millimeter wave radar module 208 may move, it may be recognized by the millimeter wave radar module 208.

In one possible implementation, the millimeter-wave radar antenna (including the transmit antenna and the receive antenna) may be packaged in one chip with the millimeter-wave radar module 208.

In one possible implementation, the millimeter-wave radar antenna (including the transmit antenna and the receive antenna) may be located off-chip from which the millimeter-wave radar module 208 is located. The antennas (including the transmitting antenna and the receiving antenna) of millimeter-wave radar module 208 may be located at different locations on electronic device 200 than millimeter-wave radar module 208. For example, the antenna of millimeter-wave radar module 208 may be disposed on a frame of a display screen of electronic device 200, and the chip on which millimeter-wave radar module 208 is disposed may be on a back surface of a System On Chip (SOC), a motherboard, or the display screen.

A data sharing system provided in an embodiment of the present application is described below.

Fig. 3 shows an architecture diagram of a data sharing system provided in an embodiment of the present application.

As shown in fig. 3, the data sharing system 30 includes an electronic device 100 and an electronic device 200. The electronic device 100 may communicate with the electronic device 200 through bluetooth communication and/or Wi-Fi communication, and in other embodiments, the electronic device 100 may communicate with the electronic device 200 through a mobile technology such as 5G.

The electronic device 100 may be a portable device such as a mobile phone, a wearable device (e.g., a smart band), a tablet computer, a laptop computer (laptop), a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, and the like.

The electronic device 200 may be a portable device such as a mobile phone, a wearable device (e.g., a smart band), a tablet computer, a laptop computer (laptop), a handheld computer, a notebook computer, a smart television, a smart large screen, an ultra-mobile personal computer (UMPC), a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, and the like.

Among them, the millimeter wave radar antenna (including the transmitting antenna and the receiving antenna) on the electronic device 200 is set at different positions based on the device type so as to transmit and receive the millimeter wave signal conveniently. For example, when the electronic device 200 is a tablet computer, a notebook computer, a smart television, or a smart large screen, the millimeter-wave radar antenna on the electronic device 200 may be disposed around a frame of the display screen 205, and the millimeter-wave radar antenna and the display screen 205 are disposed on the same side surface. When the electronic device 200 is a notebook computer, the electronic device 200 is further provided with a keyboard and a touch pad, and the millimeter wave radar antenna on the electronic device 200 may also be disposed around a frame of the keyboard, around the touch pad or inside the touch pad, or around a frame of the display screen. The millimeter wave radar antenna is arranged at the position, so that when the electronic equipment 200 is used, the position of the shielding object and/or the movement of the shielding object can be conveniently detected, and the intention of a user can be accurately judged. In some embodiments, a millimeter-wave radar antenna may be disposed within a housing of electronic device 200 through which millimeter-wave signals may pass for detection.

In the embodiment of the present application, the electronic device 100 is exemplarily used as a mobile phone, and the electronic device 200 is used as a tablet computer for description. Among them, the electronic device 200 may be referred to as a first electronic device in the embodiment of the present application, and the electronic device 100 may be referred to as a second electronic device in the embodiment of the present application.

A data sharing scenario provided by the embodiment of the present application is described below.

Fig. 4 shows a data sharing scenario provided in an embodiment of the present application.

As shown in fig. 4, the electronic device 200 may detect a movement of the obstacle (for example, a left movement, a right movement, a movement closer to the electronic device 200, a movement further away from the electronic device 200, or the like) by the millimeter wave radar module, and acquire motion data (including gyro sensor data and acceleration sensor data) of the electronic device 100 to which the bluetooth connection has been established. When the electronic device 200 determines that the movement of the electronic device 100 is consistent with the movement of the obstruction based on the motion data of the electronic device 100, the electronic device 200 may determine that the obstruction is the electronic device 200. Accordingly, the electronic device 200 may perform an operation corresponding to the moving direction, for example, the electronic device 200 transmits file data on the electronic device 200 to the electronic device 100, or the electronic device 200 instructs the electronic device 100 to transmit the file data to the electronic device 200. In this way, a user only needs to perform a specific movement operation on the electronic device 100 in the millimeter wave radar detection area of the electronic device 200 to complete the transmission of the file data (e.g., picture data, video data, audio data, document data, etc.) between the electronic device 100 and the electronic device 200, thereby simplifying the operation steps of sharing data between the electronic device 100 and the electronic device 200.

In a specific implementation manner, in order to improve the accuracy of the intention identification, the electronic device 100 triggers the file transmission only when moving in a partial area of the detection area, and the partial area can be understood as a reliable area for triggering the file transmission. When the electronic device 100 moves outside a partial area of the detection area, file transmission is not triggered to avoid erroneous transmission. For example, the detection area of the millimeter wave radar module may be a conical area, the center of the detection area is the position where the millimeter wave radar antenna is located, the central angle of the detection area is θ, and the radius is r1. In one possible implementation, the reliable region may be a conical region with a radius r2 and a central angle θ. In one possible implementation, the central angle of the reliable region may be smaller than the central angle θ of the detection region. In one possible implementation, the reliable region is a region parallel to the millimeter wave radar antenna.

In the following embodiments, the first motion is illustrated by swinging to the left, and the second motion is illustrated by swinging to the right, and in other embodiments, the first motion and the second motion may also represent other ways of moving.

In the following, with reference to the data sharing scenario shown in fig. 4, the data sharing process between the electronic device 100 and the electronic device 200 provided in this embodiment is described by taking picture data sharing as an example. Among them, the electronic device 200 may be referred to as a first electronic device in the embodiment of the present application, and the electronic device 100 may be referred to as a second electronic device in the embodiment of the present application.

In some application scenarios, the electronic device 100 may display a browsing interface including file data (e.g., picture data). When the electronic device 100 displays the browsing interface, the electronic device 100 may receive an operation of the user waving to the left within the detection area of the millimeter wave radar on the electronic device 200. The electronic device 200 may detect the moving direction of the blocking object through the millimeter wave radar, and acquire the motion data on the electronic device 100 through bluetooth. The electronic device 200 may determine whether the moving direction of the blocking object coincides with the moving direction of the electronic device 100 in the same time period based on the moving direction of the blocking object and the motion data of the electronic device 100. When the moving direction of the blocking object is consistent with the moving direction of the electronic device 100 in the same time period, the electronic device 200 may establish a file transfer connection with the electronic device 100 and request the electronic device 100 to send file data on the currently displayed interface to the electronic device 200. In this way, the operation steps of sharing data between the electronic device 100 and the electronic device 200 can be simplified.

As shown in fig. 5A, the electronic device 100 displays an interface 510 having a home screen (home screen), and a page in which application icons are placed is displayed in the interface 510, and the page includes a plurality of application icons (e.g., a weather application icon, a stock application icon, a calculator application icon, a setting application icon, a mail application icon, a music application icon, a video application icon, a browser application icon, a map application icon, a gallery application icon 511, and the like). Optionally, page indicators are further displayed below the application icons to indicate the total number of pages on the home screen and the position relationship between the currently displayed page and other pages. For example, the interface 510 of home screen may include three pages, and a white dot in the page indicator may indicate that the currently displayed page is the rightmost one of the three pages. Further optionally, there are a plurality of tray icons (e.g., a dialing application icon, an information application icon, a contacts application icon, a camera application icon) below the page indicator, which remain displayed upon page switching.

As shown in fig. 5C, the title of the picture presentation interface 530 may be "9/20/2020". The picture display interface 530 includes a picture 536 and a menu 537. The menu 537 includes a sharing control 531, a collection control 532, an editing control 533, a deletion control 534, and a plurality of controls 535. The sharing control 531 may be used to trigger opening of the file sharing interface and gradually guide the user to perform an input operation, so as to complete the sharing of the picture 536. Favorites control 532 may be used to trigger the favoring of the picture 536 to a picture favorites folder. The editing controls 533 may be used to trigger editing functions for rotating, cropping, adding filters, blurring, etc. the picture 536. The delete control 534 can be used to trigger the deletion of the picture 536. More controls 535 may be used to trigger the opening of more functions related to the picture 536.

In some embodiments, the menu 537 is optional. The menu 537 can be hidden in the picture presentation interface 530, for example, when the user clicks on the picture 536, the user can trigger the electronic device 100 to hide the menu 537. When the user clicks the menu 537 again, the electronic device 100 may be triggered to display the menu 537.

When the electronic device 100 displays the picture displaying interface 530, an operation of swinging the electronic device to the left by the user may be received. During a left swing of the electronic device 100 by the user, the electronic device 100 may record motion data during the user swing, wherein the motion data includes sensor data and acceleration data. The electronic device 200 may detect the movement direction of the blocking object by the millimeter wave radar, and acquire the movement data on the electronic device 100, which has established the bluetooth connection, by bluetooth. After the electronic device 200 acquires the motion data of the electronic device 100, it may be determined whether the moving direction of the electronic device 100 is consistent with the motion direction of the blocking object based on the motion data of the electronic device 100, if so, the electronic device 200 may interact file connection parameters (for example, wi-Fi connection parameters) with the electronic device 100, and the electronic device 200 may establish a file transfer connection with the electronic device 100 and request the electronic device 100 to send file data (i.e., the above-mentioned picture 536) currently displayed on the display screen of the electronic device 100 to the electronic device 200. The file transfer connection may be a Wi-Fi direct (e.g., a wireless fidelity peer to peer (Wi-Fi P2P)), wi-Fi softAP, ultra-wideband (UWB) or other communication technology connection.

As shown in fig. 5D, after receiving the picture data sent by the electronic device 100, the electronic device 200 may display a picture display interface 540. The picture display interface 540 may include a picture 541. The picture 541 is the same as the picture 536 displayed in the picture displaying interface 530 by the electronic device 100 in fig. 5C.

In a possible implementation manner, after the first file transfer is completed, the file transfer connection between the electronic device 200 and the electronic device 100 is disconnected, and the bluetooth connection between the electronic device 200 and the electronic device 100 maintains a connection state. The electronic device 200 and the electronic device 100 may again interact with parameters of the file transfer connection (e.g., wi-Fi connection parameters) through the maintained bluetooth connection to re-establish the file transfer connection and to re-transfer the file. After the file transmission is finished, the file transmission connection is disconnected, so that the power consumption can be saved; and the Bluetooth connection is kept, so that the file transmission connection can be quickly established in the next transmission, and the transmission speed is improved. And keeping the power consumption of the bluetooth connection low.

In some application scenarios, the electronic device 200 may display a browsing interface including file data (e.g., picture data). When the electronic apparatus 200 displays the browsing interface, the electronic apparatus 100 may receive an operation of the user waving to the right within a detection area of the millimeter wave radar on the electronic apparatus 200. The electronic device 200 may detect the moving direction of the blocking object through the millimeter wave radar, and acquire the motion data on the electronic device 100 through bluetooth. The electronic device 200 may determine whether the moving direction of the blocking object coincides with the moving direction of the electronic device 100 in the same time period based on the moving direction of the blocking object and the motion data of the electronic device 100. When the moving direction of the blocking object is consistent with the moving direction of the electronic device 100 in the same time period, the electronic device 200 may establish a file transfer connection with the electronic device 100, and send file data included in the interface displayed on the electronic device 200 to the electronic device 100. In this way, the operation steps of sharing data between the electronic device 100 and the electronic device 200 can be simplified.

As shown in fig. 6A, the electronic apparatus 200 displays an interface 610 with a home screen.

A hardware system of an electronic device 200 provided in the embodiment of the present application is described below.

Fig. 7 illustrates a hardware system of an electronic device 200 according to an embodiment of the present disclosure. The hardware system of electronic device 200 may include, but is not limited to, processor 701, millimeter wave radar module 702, power module 703, crystal module 704, one transmit antenna (transmit antenna 705), and three receive antennas (receive antenna 706, receive antenna 707, receive antenna 708).

Millimeter-wave radar module 702 may be configured to, among other things, transmit electromagnetic waves (i.e., millimeter waves) via transmit antenna 705 and receive electromagnetic waves (i.e., echo signals) reflected from an obstruction via at least one receive antenna (e.g., receive antenna 706, receive antenna 707, and receive antenna 708). The millimeter wave radar module 702 performs distance measurement, speed measurement, and orientation measurement on the obstruction by sending and receiving parameters of electromagnetic waves. Millimeter wave radar module 702 may measure distance, speed, and orientation for multiple obstacles. Millimeter wave radar module 702 may measure the distance to an obstruction by the time difference between the transmission and reception of electromagnetic waves. Millimeter-wave radar module 702 may measure the velocity of an obstruction by sending and receiving the doppler effect of electromagnetic waves. When millimeter-wave radar module 702 is configured with at least three receiving antennas, millimeter-wave radar module 702 may calculate an azimuth angle (including a horizontal angle and a vertical angle) of an obstacle by using phase differences of electromagnetic waves reflected by the same obstacle, which are received by at least three receiving antennas.

The millimeter wave radar module 702 may send millimeter wave data of an obstruction to the processor 701 after measuring the millimeter wave data (including the distance, the moving speed, and the azimuth angle of the obstruction) of the obstruction.

The processor 701 may be a Central Processing Unit (CPU) or an Application Processor (AP). When the processor 701 determines that the type of movement action of the obstacle is a specified type (for example, movement to the left direction of the electronic apparatus 200 or movement to the right direction of the electronic apparatus 200) based on the millimeter wave data of the obstacle, the processor 701 may acquire, through the bluetooth chip 709, motion data (including gyro sensor data and acceleration sensor data) on the electronic apparatus 100 to which the bluetooth connection with the electronic apparatus 200 has been established. When the processor 701 determines that the type of the movement action of the obstruction is consistent with the type of the movement action of the electronic device 100 based on the motion data of the electronic device 100 and the millimeter wave data of the obstruction, the processor 701 may instruct the WLAN chip 710 to establish a Wi-Fi direct (e.g., a wireless fidelity peer to peer (Wi-Fi P2P)) communication technology connection with the electronic device 100, such as Wi-Fi softAP.

The WLAN chip 710 may be used to transmit file data included in a current display interface on the display screen of the electronic device 200 to the electronic device 100.

In some embodiments, the WLAN chip 710 may receive the file data transmitted by the electronic device 100, which is included in the current display interface on the display screen of the electronic device 100. The WLAN chip 710 may transmit file data of the electronic device 100 to the processor 701. The processor 701 may instruct a display screen (not shown in fig. 7) of the electronic device 200 to display the file data of the electronic device 100.

In some embodiments, the hardware system of the electronic device 200 may further include a UWB chip (not shown in fig. 7) and a UWB antenna (not shown in fig. 7) coupled to the UWB chip. When the processor 701 of the electronic device 200 determines that the movement action type of the obstruction is consistent with the movement action type of the electronic device 100 based on the motion data of the electronic device 100 and the millimeter wave data of the obstruction, the processor 701 may instruct the UWB chip to establish a UWB connection with the electronic device 100. The UWB chip may transmit file data included in a current display interface on the display screen of the electronic device 200 to the electronic device 100. Alternatively, the UWB chip may receive file data transmitted by the electronic device 100 included in a current display interface on the display screen of the electronic device 100. The UWB chip may transmit the file data of the electronic device 100 to the processor 701. The processor 701 may instruct a display screen (not shown in fig. 7) of the electronic device 200 to display the file data of the electronic device 100.

Power module 703 may be used to power millimeter-wave radar module 702.

Crystal module 704 may be used to provide a clock signal for millimeter wave radar module 702. Millimeter-wave radar module 702 may transmit millimeter-wave signals through the transmit antenna at specified periods (e.g., every 10 ms) based on the clock signal.

In some embodiments, millimeter-wave radar module 702 is in a state of constant operation while electronic device 200 is operating. Millimeter-wave radar module 702 may be in an Idle (Idle) state when no obstruction is detected, in which Idle state (i.e., the first state) millimeter-wave radar module 702 may transmit millimeter-wave signals through the transmit antenna at a first period (e.g., every 100 ms). When millimeter-wave radar module 702 detects an obstruction, millimeter-wave radar module 702 may switch to an Active (Active) state in which millimeter-wave radar module 702 may transmit millimeter-wave signals through a transmit antenna at a second period (e.g., every 10 ms). The first period is greater than the second period, that is, the duty ratio of the millimeter wave signal in the active state is higher than that in the idle state. Therefore, the power consumption of the millimeter wave radar can be saved when no shielding object exists, and the accuracy of the millimeter wave radar for detecting the shielding object is improved when the shielding object exists.

In some particular embodiments, the state of millimeter wave radar module 702 may be controlled by processor 701. For example, when an obstruction (for example, electronic device 100) is in front of electronic device 200, millimeter wave radar module 702 receives a millimeter wave signal returned from the obstruction through a receiving antenna, millimeter wave radar module 702 sends the returned millimeter wave signal to processor 701, processor 701 determines that millimeter wave radar module 702 detects the obstruction, and processor 701 sends a first control instruction to millimeter wave radar module 702. After millimeter-wave radar module 702 receives the first control instruction, millimeter-wave radar module 702 adjusts the millimeter-wave signal to be transmitted at the second period.

In some specific embodiments, millimeter-wave radar module 702 includes a controller, which may be a control device such as an MCU, and a signal transceiver for transmitting and receiving millimeter-wave signals. When an obstruction (for example, the electronic device 100) is in front of the electronic device 200, the signal transceiver receives a millimeter wave signal returned from the obstruction through the receiving antenna, the signal transceiver sends the returned millimeter wave signal to the controller, the controller determines that the millimeter wave radar module 702 detects the obstruction, and the controller sends a second control instruction to the signal transceiver. And after the signal transceiver receives the second control instruction, the signal transceiver adjusts the millimeter wave signal to be transmitted in a second period.

The frequency band of the millimeter wave radar module 702 transmitting the electromagnetic wave through the transmitting antenna 1 may include 24GHz, 60GHz, 77GHz, 120GHz, and the like. The higher the frequency band is, the longer the effective detection distance of the millimeter wave radar module 702 to the obstruction is.

In one possible implementation, the millimeter-wave radar antenna (including the transmit antenna and the receive antenna) may be packaged in one chip with the millimeter-wave radar module 702.

In one possible implementation, millimeter-wave radar antennas (including transmit antennas and receive antennas) may be located off-chip from millimeter-wave radar module 702. The antennas of millimeter-wave radar module 702 (including the transmit antenna and the receive antenna), among other things, may be located at different locations on electronic device 200 than millimeter-wave radar module 702. For example, an antenna of millimeter-wave radar module 702 may be disposed on a bezel of a display screen of electronic device 200, and a chip on which millimeter-wave radar module 702 is located may be on a System On Chip (SOC). In this way, millimeter wave radar module 702 and the millimeter wave radar antenna are separately arranged on electronic device 200, and the occupied area of the millimeter wave radar on electronic device 200 can be saved.

In one possible implementation, the chip on which millimeter wave radar module 702 is located may be packaged in one chip with other communication modules. For example, the chip on which the millimeter-wave radar module 702 is located may be packaged as the same chip as the bluetooth chip 709 and the WLAN chip 710.

Next, a software-driven initialization process of the millimeter wave radar will be described based on the hardware system of the electronic device 200 shown in fig. 7 described above.

Fig. 8 shows a software-driven initialization process of the millimeter wave radar provided in the embodiment of the present application.

As shown in fig. 8, the software driver initialization process includes the following steps:

and S801, reading and analyzing the command issued by the upper layer by the millimeter wave radar driver.

And S802, configuring the pin functions of the chip where the millimeter wave radar module is located by the millimeter wave radar driver, wherein the pin functions comprise a pin for configuring an input function, a pin for outputting a function, a pin for interrupting a function and a pin for multiplexing the function.

S803, the millimeter wave radar driver may perform interrupt registration.

And S804, driving the millimeter wave radar to configure data for a chip where the millimeter wave radar module is located.

And S805, the millimeter wave radar driver can detect the chip where the millimeter wave radar module is located through the data interface, so that the chip where the millimeter wave radar module is located reads the data of the processor.

Next, a data acquisition flow of the millimeter wave radar will be described based on the hardware system of the electronic device 200 shown in fig. 7.

Fig. 9 shows a data acquisition flow of the millimeter wave radar module provided in the embodiment of the present application.

As shown in fig. 9, the data acquisition process of the millimeter wave radar may include the following steps:

and S901, issuing a data acquisition command by the HAL layer.

S902, the data buffer of the processor has no data, and the thread of the processor of the electronic device 200 enters the wait queue.

And S903 triggering interruption when a First In First Out (FIFO) buffer area of a chip where the millimeter wave radar module is located reaches a preset value.

And S904, the processor reads data from the FIFO buffer area of the chip where the millimeter wave radar module is located, enters the data buffer area, and wakes up the waiting thread.

S905 indicates that the processor is waiting for the thread to change to the running state, and reads the data in the data buffer for processing by the upper layers, such as the HAL layer and the application layer.

A software architecture of the data sharing system provided in the embodiment of the present application is described below.

Fig. 10 shows a software architecture diagram of the data sharing system provided in the embodiment of the present application.

As shown in fig. 10, the data sharing system includes an electronic device 100 and an electronic device 200. The software systems of the electronic device 100 and the electronic device 200 may adopt a hierarchical architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application uses a layered architecture as an example to exemplarily illustrate software structures of the electronic device 100 and the electronic device 200.

The electronic device 100 and the electronic device 200 each include an application layer, an application framework layer, a hardware abstraction layer, and a kernel layer.

The application layer may include a series of application packages, such as data sharing applications, bluetooth applications, WLAN applications, camera applications, gallery applications, telephony applications, music applications, video applications, and the like.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

A Hardware Abstraction Layer (HAL) runs in the user space, which shields the implementation details of the hardware driver module downwards and provides hardware access services upwards.

The kernel layer is a layer between hardware and software. The inner core layer at least comprises a display driver, a camera driver, an audio driver and a sensor driver.

In an embodiment of the present application, the application layer of the electronic device 100 may include a plurality of applications (e.g., a data sharing application 1011, a bluetooth application, a WLAN application, a camera, a gallery, a call, music, a video, and so on). The application framework layers of the electronic device 100 may include bluetooth services 1012, sensor services 1013, WLAN services (not shown in fig. 10), and so on. The core layer of the electronic device 100 may include a bluetooth chip driver 1014, an acceleration sensor driver 1015, a gyroscope sensor driver 1016, a WLAN chip driver 1017, a display driver (not shown in fig. 10), an audio driver (not shown in fig. 10), and the like.

The application layer of the electronic device 200 may include a plurality of applications (e.g., data sharing application 1021, bluetooth application), WLAN application, camera application, gallery application, talk application, music application, video application, and the like). The application framework layer of the electronic device 200 may include an action recognition module 1023, a bluetooth service 1022, a WLAN service (not shown in fig. 10), and so on. The core layer of electronic device 200 may include millimeter-wave radar module driver 1024, bluetooth chip driver 1025, WLAN chip driver 1026, a display driver (not shown in fig. 10), an audio driver (not shown in fig. 10), and so forth.

The following describes exemplary work flows of software and hardware of the data sharing system in conjunction with the data sharing scenarios in the embodiments shown in fig. 5A to 5D or fig. 6A to 6E.

The HAL layer on the electronic device 200 issues a millimeter wave data acquisition command to the millimeter wave radar driver 1024 of the electronic device 200. Millimeter wave radar driver 1024 may instruct millimeter wave radar module 702 (i.e., a millimeter wave radar chip in the figure) to transmit a millimeter wave signal after the millimeter wave data acquisition instruction. Millimeter-wave radar module 702 may transmit a millimeter-wave signal through transmitting antenna 705 at a certain period, and receive a millimeter-wave echo reflected by an obstacle through at least three receiving antennas (including receiving antenna 706, receiving antenna 707, and receiving antenna 708). After receiving the millimeter wave echo, the millimeter wave radar module 702 may obtain millimeter wave data (including the distance, the moving speed, and the azimuth angle of the obstacle) based on millimeter wave echo analysis. Millimeter wave radar chip driver 1024 may obtain millimeter wave data from millimeter wave radar module 702 and report the millimeter wave data to action recognition module 1023 via the HAL layer.

The motion recognition module 1023 can be used for recognizing the movement motion type of the obstruction based on the millimeter wave data, and when the movement motion type of the obstruction is a specified movement motion type (e.g. sliding left or sliding right), the motion recognition module 1023 can call the bluetooth service 1022 to acquire the motion data (including the gyroscope sensor data and the acceleration sensor data) of the device (e.g. the electronic device 100) with which the bluetooth connection is established.

Bluetooth service 1022 may instruct bluetooth chip driver 1025 to control bluetooth chip 709 to send motion data capture instructions to electronic device 100.

After acquiring the motion data acquisition command, the bluetooth chip driver 1014 on the electronic device 100 may report the motion data acquisition command to the bluetooth service 1012 through the HAL layer.

The bluetooth service 1012 may present the acquisition instruction of the motion data to the sensor service 1013. The obtaining instruction of the motion data includes a obtaining time period of the motion data, and in the obtaining time period, the electronic device 200 identifies the movement motion type of the obstruction. The sensor service 1013 may obtain acceleration sensor data from an acceleration sensor through the acceleration sensor drive 1015, obtain gyro sensor data from a gyro sensor through the gyro sensor drive 1016, and save the acceleration sensor data and the gyro sensor data in real time. After receiving the motion data acquisition instruction, the sensor service 1013 may call the bluetooth service 1012 to acquire the motion data (including the number of gyroscope sensors and the acceleration sensor data) of the electronic device 100 in the time period, and instruct the bluetooth chip to send the motion data to the bluetooth chip 709 of the electronic device 200 through the bluetooth chip driver 1014.

After receiving the motion data of the electronic device 100, the bluetooth chip 709 of the electronic device 200 may report the motion data to the bluetooth service 1022 through the bluetooth chip driver 1025. The bluetooth service 1022 presents the motion data of the electronic device 100 and the device identification of the electronic device 100 to the motion recognition module 1023. The motion recognition module 1023 may determine whether the type of the movement motion of the electronic device 100 is the same as the type of the movement motion of the obstruction based on the motion data of the electronic device 100. When the type of the movement action of the electronic device 100 is the same as the type of the movement action of the obstruction, the action recognition module 1023 can render the type of the movement action of the electronic device 100 and the device identification of the electronic device 100 to the data sharing application 1021.

The data sharing application 1021 may establish a file transfer connection with the electronic device 100 after receiving the mobile action type of the electronic device 100 and the device identifier of the electronic device 100. The file transfer connection may be a Wi-Fi direct (e.g., wi-Fi P2P), wi-Fi softAP, UWB, or other communication technology connection.

When the type of the movement action of the electronic device 100 is the first type (for example, left movement), the data sharing application 1021 may call the bluetooth service 1022 or a WLAN service (not shown in fig. 10) or a UWB service (not shown in fig. 10), and transmit a file data obtaining request to the electronic device 100, where the file data obtaining request is used for requesting the electronic device 100 to transmit file data included in the currently displayed interface to the electronic device 200.

When the movement action type of the electronic device 100 is the second type (for example, right movement), the data sharing application 1021 may identify whether the currently displayed interface of the electronic device 200 includes file data, and if so, the data sharing application 1021 may send the file data to the electronic device 200 through a file transmission connection.

The following describes a flow of a data sharing method provided in an embodiment of the present application.

Fig. 11 shows a flowchart of a data sharing method according to an embodiment of the present application.

As shown in fig. 11, the data sharing method may include the following steps:

s1101, the electronic device 100 establishes Bluetooth connection with the electronic device 100.

S1102, the electronic device 100 displays a first interface, where the first interface includes a first file.

The type of the first file may include, among others, pictures, video, audio, documents, tables, folders, compressed packages, and so on.

For example, the first interface may be the picture display interface 530 shown in fig. 5C, and the first file may be a picture 536 included in the picture display interface 530. For details, reference may be made to the foregoing embodiment shown in fig. 5C, which is not described herein again.

S1103, the electronic device 100 receives a waving operation of the electronic device 100 by the user.

S1104, in response to the user' S waving operation of the electronic device 100, the electronic device 100 may record the motion data (i.e., the first motion data) in the course of the waving operation. Wherein the motion data comprises gyroscope sensor data and acceleration sensor data.

S1105, the electronic device 200 may detect the motion type of the obstruction through the millimeter wave radar module, and determine whether the motion type of the obstruction is the first type (i.e. the first motion). If yes, step S1106 is executed, and the electronic device 200 sends a motion data acquisition request to the electronic device 100 through bluetooth.

The principle of the millimeter wave radar module detecting the motion type of the blocking object may refer to the embodiment shown in fig. 2 or fig. 8, and is not described herein again.

The first type may include moving to a first direction (e.g., left direction) and/or the moving speed satisfies a first preset speed condition. Wherein the first preset speed condition comprises: the moving speed is greater than a first speed value (e.g., 0.1 m/s). In one possible implementation, the preset speed condition includes: the moving speed is greater than a first speed value (e.g., 0.1 m/s) and less than a second speed value (e.g., 0.5 m/s)), wherein the first speed value is less than the second speed value.

The motion data acquisition request sent by the electronic device 200 through bluetooth includes time information when the electronic device 200 detects the obstruction through the millimeter wave radar module.

In the embodiment of the present application, the motion data acquisition request in step S1106 described above may be referred to as a first acquisition request.

In a possible implementation manner, before detecting the motion action type of the obstruction, the electronic device 200 may further detect a distance between the obstruction and the millimeter wave radar antenna, and if the distance between the obstruction and the millimeter wave radar antenna is less than a preset distance (for example, 0.2 m), the electronic device 200 may detect the motion action type of the obstruction. If the distance between the obstacle and the millimeter wave radar antenna is greater than or equal to a preset distance (e.g., 0.2 m), the electronic device 200 does not detect the motion type of the obstacle. Therefore, the file data sharing can be prevented from being started by the mistaken touch of the user.

In a possible implementation manner, before detecting the motion action type of the blocking object, the electronic device 200 may further detect an included angle of the blocking object with respect to a perpendicular line of the plane where the millimeter wave radar antenna is located, and if the included angle of the blocking object with respect to the perpendicular line of the plane where the millimeter wave radar antenna is located is smaller than a preset angle (for example, 30 degrees), the electronic device 200 may detect the motion action type of the blocking object. If the included angle of the shielding object with respect to the perpendicular to the plane where the millimeter wave radar antenna is located is greater than or equal to a preset angle (for example, 30 degrees), the electronic device 200 may not detect the motion type of the shielding object. Therefore, the file data sharing can be prevented from being started by the mistaken touch of the user.

S1107, the electronic device 100 sends the motion data of the electronic device 100 to the electronic device 200 via bluetooth in response to the motion data acquisition request.

Wherein the motion data of the electronic device 100 includes gyroscope sensor data and acceleration sensor data of the electronic device 100 during a period of time when the electronic device 200 detects the obstruction.

S1108, the electronic device 200 determines whether the motion action type of the electronic device 100 is the first type based on the motion data of the electronic device 100, that is, whether the first motion data satisfies the first condition, and if the first motion data satisfies the first condition, the motion action type of the electronic device 100 is the first type. In one implementation, the first condition includes: the acceleration sensor data is used to instruct a second electronic device (i.e., electronic device 100) to perform a first motion; and/or, the gyroscopic sensor data includes data for instructing a second electronic device (i.e., electronic device 100) to perform the first motion. In other ways, the first condition may also be whether the moving speed is greater than a first speed value.

If yes, step S1109 is executed, where the electronic device 200 sends a file acquisition request to the electronic device 100 through bluetooth. Specifically, when the first motion data satisfies the first condition, the electronic device 100 transmits a file acquisition request to the electronic device 200.

S1110, after receiving the file obtaining request, the electronic device 100 may establish a file transmission connection with the electronic device 200.

The file transfer connection may be a Wi-Fi direct (e.g., a wireless fidelity peer to peer (Wi-Fi P2P)), wi-Fi softAP, ultra-wideband (UWB), or other communication technology connection.

S1111, the electronic device 100 may transmit the first file to the electronic device 200.

After the electronic device 200 receives the first file transmitted by the electronic device 100, the electronic device 200 may directly display the content of the first file. For example, if the first file is a picture, the electronic device 200 directly displays the picture; if the first file is a video or an audio, the electronic device 200 plays the video or the audio. If the first file is a document or a form, the electronic device 200 may open and display the document or the form directly through a document application or a form application.

In one possible implementation manner, after the electronic device 200 receives the first file sent by the electronic device 100, the electronic device 200 may save the received first file to the local. The electronic device 200 may then receive and display the contents of the first file in response to the user input.

In one possible implementation, before detecting the type of motion action of the obstruction, the electronic device 200 may also detect a distance of the obstruction from the millimeter wave radar antenna to determine whether the electronic device 100 is within a reliable range. If the distance between the electronic device 100 and the millimeter wave radar antenna is smaller than the preset distance (e.g., 0.2 m), it may be considered that the electronic device 100 is within the reliable range, and then no file transmission is performed between the electronic device 200 and the electronic device 100. Specifically, the distance between the electronic device 100 and the millimeter wave radar antenna is less than the preset distance, the electronic device 200 may detect the motion action type of the obstruction, or the electronic device 200 may continue to acquire the motion data of the electronic device 100 (for example, send a motion data acquisition request). If the distance between the electronic device 100 and the millimeter wave radar antenna is greater than or equal to the preset distance (e.g., 0.2 m), it may be considered that the electronic device 100 is out of the reliable range, and then file transmission is performed between the electronic device 200 and the electronic device 100. Specifically, the distance between the obstruction and the millimeter wave radar antenna is greater than the preset distance, the electronic device 200 does not detect the motion action type of the obstruction, or the electronic device 200 may not continue to acquire the motion data of the electronic device 100 (e.g., does not send a motion data acquisition request). Therefore, file data sharing can be prevented from being started by mistaken touch of a user.

In one possible implementation, before detecting the motion action type of the obstruction, the electronic device 200 may further detect an angle of the obstruction with respect to a perpendicular to a plane in which the millimeter wave radar antenna is located to determine whether the electronic device 100 is within a reliable range. If the included angle of the blocking object with respect to the perpendicular to the plane where the millimeter wave radar antenna is located is smaller than a preset angle (for example, 30 degrees), it may be considered that whether the electronic device 100 is located within the reliable range, and then the electronic device 200 may detect the motion type of the blocking object. If the included angle of the shielding object with respect to the perpendicular to the plane where the millimeter wave radar antenna is located is greater than or equal to a preset angle (for example, 30 degrees), it may be considered that the electronic device 100 is located outside the reliable range, and the electronic device 200 may not detect the motion type of the shielding object. Therefore, file data sharing can be prevented from being started by mistaken touch of a user.

In some embodiments, millimeter-wave radar module 702 may transmit millimeter-wave signals through the transmit antenna at a second periodicity (e.g., every 10 ms) when electronic device 100 is within a reliable range. When electronic device 100 is outside the reliable range, millimeter-wave radar module 702 may transmit the millimeter-wave signal through the transmit antenna for a first period to better conserve power consumption.

In some embodiments, the electronic device 200 may connect to an Access Point (AP) of the same WLAN or to the same server (which may be the same physical server or the same cloud server) with the electronic device 100. The electronic device 200 and the electronic device 100 have the same account ID, or the account ID on the electronic device 200 and the account ID on the electronic device 100 are authorized accounts. After recognizing that the type of the motion action of the obstruction is the first type (for example, moving left) through the millimeter wave radar module, the electronic device 200 may send a motion data acquisition request, which may include an account ID of the electronic device 200, to the electronic device 100 through the AP or the server. After receiving the motion data acquisition request, the electronic device 100 may determine whether the account ID of the electronic device 200 is the same as or mutually authorized with the account ID of the electronic device 100, and if so, the electronic device 100 may send the motion data (including the gyroscope sensor data and the acceleration sensor data) of the electronic device 100 to the electronic device 200 through an AP or a server. When determining that the motion action type of the electronic device 100 is the first type based on the motion data of the electronic device 100, the electronic device 200 may send a file acquisition request to the electronic device 100 through the AP or the server. The electronic device 100 may transmit the currently displayed file data to the electronic device 200 through the AP or the server. In this way, the electronic device 100 verifies the account ID of the electronic device 200, so that file data sharing between two mutually trusted devices can be ensured, and the privacy of the user can be protected.

In a possible implementation manner, the electronic device 200 may connect to the same AP of the WLAN or to the same server (which may be the same physical server or the same cloud server) as the electronic device 100. After the electronic device 200 identifies that the motion action type of the blocking object is the first type through the millimeter wave radar module, the motion data acquisition request may be sent to other multiple devices through the AP. The other plurality of devices may transmit respective motion data (including gyro sensor data and acceleration sensor data) to the electronic device 200 upon receiving the motion data acquisition request. The electronic device 200 may determine that the motion action type of the electronic device 100 is the first type from the motion data of other devices. The electronic apparatus 200 may transmit a file acquisition request to the electronic apparatus 100 through the AP. The electronic apparatus 100 may transmit the currently displayed file data to the electronic apparatus 200 through the AP.

Through the data sharing method provided by the embodiment of the application, the electronic device 100 can display a browsing interface including file data (e.g., picture data). When the electronic device 100 displays the browsing interface, the electronic device 100 may receive an operation of the user waving to the left within the detection area of the millimeter wave radar on the electronic device 200. The electronic device 200 may detect the moving direction of the blocking object through the millimeter wave radar, and acquire the motion data on the electronic device 100 through bluetooth. The electronic device 200 may determine whether the moving direction of the blocking object coincides with the moving direction of the electronic device 100 in the same time period based on the moving direction of the blocking object and the motion data of the electronic device 100. When the moving direction of the blocking object is consistent with the moving direction of the electronic device 100 in the same time period, the electronic device 200 may establish a file transfer connection with the electronic device 100 and request the electronic device 100 to send file data on the currently displayed interface to the electronic device 200. In this way, the operation steps of sharing data between the electronic device 100 and the electronic device 200 can be simplified.

A flow of a data sharing method provided in another embodiment of the present application is described below.

As shown in fig. 12, the data sharing method may include the following steps:

s1201, the electronic device 100 establishes Bluetooth connection with the electronic device 100.

S1202, the electronic device 200 displays a second interface, where the second interface includes a second file.

The type of the second file may include, among others, pictures, video, audio, documents, tables, folders, compressed packages, and so on.

For example, the second interface may be the picture display interface 530 shown in fig. 6C, and the first file may be a picture 636 included in the picture display interface 630. For details, reference may be made to the foregoing embodiment shown in fig. 6C, which is not described herein again.

S1203, the electronic device 100 receives a waving operation of the electronic device 100 by the user.

S1204, in response to the waving operation of the electronic device 100 by the user, recording the motion data (i.e., the second motion data) during the waving operation.

S1205, the electronic device 200 may detect the motion action type of the obstruction through the millimeter wave chip, and determine whether the motion action type of the obstruction is the second type (i.e., the second motion). If yes, step S1206 is executed, and the electronic device 200 sends a motion data obtaining request to the electronic device 100 through bluetooth.

The second type may comprise moving to a second direction (e.g. right direction) and/or the speed of movement meets a second preset speed condition. Wherein the first preset speed condition comprises: the moving speed is greater than a first speed value (e.g., 0.1 m/s). In one possible implementation, the preset speed condition includes: the moving speed is greater than a first speed value (e.g., 0.1 m/s) and less than a second speed value (e.g., 0.5 m/s)), wherein the first speed value is less than the second speed value.

In the embodiment of the present application, the motion data acquisition request in step S1206 described above may be referred to as a second acquisition request.

S1207, the electronic device 100 transmits the motion data of the electronic device 100 to the electronic device 200 via bluetooth.

Wherein the motion data of the electronic device 100 includes gyroscope sensor data and acceleration sensor data of the electronic device 100 during a time period when the electronic device 200 detects the obstruction.

S1208, the electronic device 200 determines whether the movement action type of the electronic device 100 is the second type based on the movement data of the electronic device 100, that is, whether the second movement data satisfies the second condition, and if the second movement data satisfies the second condition, the movement action type of the electronic device 100 is the second type. In one implementation, the second condition includes: acceleration sensor data for instructing the second electronic device (i.e., electronic device 100) to perform the second motion; and/or the gyroscopic sensor data includes data for instructing a second electronic device (i.e., electronic device 100) to perform a second motion. In other ways, the second condition may also be whether the moving speed is greater than a second speed value.

If yes, step S1209 is executed to enable the electronic device 200 to establish a file transfer connection with the electronic device 100. Specifically, when the second motion data satisfies the second condition, the electronic device 200 transmits a file acquisition request to the electronic device 100.

S1210, the electronic device 200 transmits the second file to the electronic device 100.

After the electronic device 100 receives the second file sent by the electronic device 200, the electronic device 100 may directly display the content of the second file. For example, if the second file is a picture, the electronic device 100 directly displays the picture; if the second file is a video or audio, the electronic device 100 plays the video or audio. If the second file is a document or a form, the electronic device 100 may open and display the document or the form directly through a document application or a form application.

In one possible implementation, after the electronic device 100 receives the second file sent by the electronic device 200, the electronic device 200 may save the received second file to the local. The electronic device 200 may then receive and display the contents of the second file in response to the user input.

In some embodiments, the electronic device 200 may connect to the same AP of the WLAN or to the same server (which may be the same physical server or the same cloud server) as the electronic device 100. The electronic device 200 and the electronic device 100 have the same account ID, or the account ID on the electronic device 200 and the account ID on the electronic device 100 are authorized accounts. After recognizing that the type of the motion action of the obstruction is the second type (for example, moving to the right) through the millimeter wave radar module, the electronic device 200 may send a motion data acquisition request, which may include an account ID of the electronic device 200, to the electronic device 100 through the AP or the server. After receiving the motion data acquisition request, the electronic device 100 may determine whether the account ID of the electronic device 200 is the same as the account ID of the electronic device 100 or is an authorized account for each other, and if so, the electronic device 100 may send the motion data (including the gyroscope sensor data and the acceleration sensor data) of the electronic device 100 to the electronic device 200 through the AP or the server.

Through the data sharing method provided by the embodiment of the application, the electronic device 200 can display a browsing interface including file data (e.g., picture data). When the electronic apparatus 200 displays the browsing interface, the electronic apparatus 100 may receive an operation of the user waving to the right within a detection area of the millimeter wave radar on the electronic apparatus 200. The electronic device 200 may detect the moving direction of the blocking object through the millimeter wave radar, and acquire the motion data on the electronic device 100 through bluetooth. The electronic device 200 may determine whether the moving direction of the blocking object is consistent with the moving direction of the electronic device 100 in the same time period based on the moving direction of the blocking object and the motion data of the electronic device 100. When the moving direction of the blocking object is consistent with the moving direction of the electronic device 100 in the same time period, the electronic device 200 may establish a file transfer connection with the electronic device 100, and send file data included in the interface displayed on the electronic device 200 to the electronic device 100. In this way, the operation steps of sharing data between the electronic device 100 and the electronic device 200 can be simplified.
