For ease of understanding, a specific flow in an embodiment of the present application is described below with reference to fig. 2.

Fig. 2 is a flowchart of an embodiment of a method for screen projection of a device according to an embodiment of the present application.

In the embodiment shown in fig. 2, the method may comprise the steps of:

step 201, receiving a screen projection request sent by a sending end by taking ultrasonic waves as an information carrier.

The scheme is mainly suitable for a cross-equipment screen projection scene, is particularly suitable for a multi-person conference mode in which two or more persons are present, is also suitable for a single-person mode, and is not limited herein. In this embodiment, before the sending end and the receiving end perform networking screen projection, the sending end sends a screen projection request to the receiving end by using ultrasonic waves as an information carrier. It should be noted that, because the technical problem that the equipment screen-throwing method provided by the present solution mainly solves is how to enable the screen-throwing person to skip the tedious operations such as connecting the equipment to be screened and inputting the screen-throwing code, the same space (the same room) where the screen-throwing person and the equipment to be screened are located can be ensured, thereby avoiding that someone triggers the screen-throwing operation at will.

For example, when the user a and the device to be screen-projected are simultaneously present in the room 1, the user a can skip the tedious operations of connecting the device to be screen-projected and inputting the screen-projected code to directly perform the screen-projected operation under the condition that the user a has the screen-projected authority. If the user B who is not in the room 1 and has the screen-throwing authority can directly skip the complicated operations such as connecting the screen-throwing equipment to be thrown and inputting the screen-throwing code to perform the screen-throwing operation, the user a in the room 1 does not know who initiates the screen-throwing operation, and it is difficult to determine whether someone intentionally breaks down, and if the important meeting in the room 1 suddenly appears, the screen-throwing picture will have adverse effects on the meeting. There is also a possibility that the screen-throwing operation is triggered by mistake, and if the user who performs the screen-throwing operation does not find and end the screen-throwing operation in time, the bad influence is brought about as well.

It should be noted that, because the scheme skips the tedious operations of manually connecting the equipment to be screen-throwing and inputting the screen-throwing code, and changes the operations into an automatic process, the system needs to perform authority verification on the sending end which is intended to perform the screen-throwing operation before replacing the user to perform the actions. Specifically, before the first ultrasonic information carried by the screen throwing request is obtained, a preset identifier (such as id) indicating the identity information of the transmitting end in the first ultrasonic information is read; and determining whether the sending end has the screen throwing authority according to the preset identification.

Based on the technical problems, the technical scheme introduces the ultrasonic technology, utilizes the characteristic that ultrasonic waves can carry information, can realize that the sending end sends information to the receiving end in an unconnected state, and simultaneously utilizes the energy loss of the ultrasonic waves in the process of penetrating through the barrier, so that whether the sending end and the receiving end of the screen throwing request are in the same space can be judged, and after the sending end and the receiving end are determined to be in the same space, complicated operations such as manual networking and screen throwing code inputting of a user can be skipped, and an automatic flow is changed.

Step 202, acquiring first ultrasonic information carried by the screen throwing request, and judging whether the sending end and the receiving end are in the same space or not based on the first ultrasonic information.

In this embodiment, the first ultrasonic information includes an ultrasonic energy value for determining whether the transmitting end and the receiving end are in the same space. Because the ultrasonic waves can be accompanied with energy loss in the process of penetrating through the barrier, the ultrasonic energy value can be compared with a first preset threshold value by utilizing the characteristic to obtain a comparison result, and whether the transmitting end and the receiving end are in the same space or not is judged according to the comparison result.

If the ultrasonic energy value exceeds a first preset threshold value, the ultrasonic wave carrying the first ultrasonic information is indicated to directly reach the receiving end without penetrating through an obstacle such as a wall, and the sending end and the receiving end can be judged to be in the same space; if the ultrasonic energy value does not exceed the first preset threshold value, it is indicated that the ultrasonic wave carrying the first ultrasonic information may not be in the same space with the receiving end, and the ultrasonic wave needs to pass through the obstacle to reach the receiving end, so that it can be determined that the transmitting end and the receiving end are not in the same space.

In some embodiments, there may be a space where the ultrasonic wave carrying the first ultrasonic information enters the receiving end through an open door or window, in which case no significant energy loss of the ultrasonic wave occurs, and if the energy value is used only to determine that a false determination may occur. Therefore, before the sending end and the receiving end are judged to be in the same space, the distance value indicating the distance between the sending end and the receiving end in the first ultrasonic information can be read; if the distance value exceeds the second preset threshold value, the fact that the sending end and the receiving end are not in the same space is judged.

Step 203, if the transmitting end and the receiving end are in the same space, transmitting second ultrasonic information including the distribution network parameters to the transmitting end, so that the transmitting end performs the screen-throwing operation after establishing a data transmission channel with the receiving end according to the distribution network parameters.

It should be noted that the network distribution parameters include the MAC address and WiFi password of the receiving end, the second ultrasonic information further includes a screen-throwing code, and the screen-throwing operation can be performed after the corresponding network distribution parameters and the screen-throwing code are obtained. Specifically, the MAC address and the WiFi password are sent to the sending end to carry out networking operation, so that the receiving end is automatically connected with a local area network corresponding to the MAC address and joins the local area network of the receiving end based on the WiFi password; and sending the screen-throwing code to a sending end for verification operation, so that a data transmission channel is established between the receiving end and the sending end, and the screen-throwing operation is performed based on a wireless screen-throwing protocol.

It should be explained that the wireless screen-throwing protocol can be Miracast/DLNA/Airplay and other protocols.

In summary, the technical problem that the method for screen projection of the device provided by the present disclosure mainly solves is how to enable a screen projector to skip cumbersome operations such as connecting a device to be projected and inputting a screen projection code, so that the same space (particularly the same room) where the screen projector and the device to be projected are located can be ensured, thereby avoiding that someone triggers the screen projection operation at will. In order to solve the problem, the method and the device have the advantages that by introducing an ultrasonic technology and utilizing the characteristic that ultrasonic waves can carry information, information can be sent to a receiving end from a sending end in an unconnected state, meanwhile, energy loss can exist in the process of penetrating through an obstacle by utilizing ultrasonic waves, whether the sending end and the receiving end of a screen throwing request are in the same space or not can be judged, and after the fact that the sending end and the receiving end are in the same space is confirmed, complicated operations such as manual networking of a user and screen throwing code input can be skipped, and the method and the device are changed into an automatic flow.

In another embodiment, in the embodiment shown in fig. 2, the method may further comprise the steps of:

step 301, an ultrasonic wave is taken as an information carrier to send a screen projection request to at least one receiving end, the screen projection request carries first ultrasonic wave information, and the first ultrasonic wave information is used for the receiving end to judge whether the sending end and the receiving end are in the same space or not so as to determine whether the screen projection request is passed or not; receiving feedback information returned by the receiving end; if the feedback information is at least one piece of second ultrasonic information containing the distribution network parameters, determining target ultrasonic information from the at least one piece of second ultrasonic information; and establishing a data transmission channel between the receiving end and the network distribution parameter in the target ultrasonic information, and then performing screen projection operation.

In this embodiment, if there are multiple receiving ends capable of responding to the screen-throwing request at the same time, information of all the receiving ends may be sent to the sending end to allow the user to select the target device to be thrown.

Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein in detail.

In particular, the present application is not limited by the order of execution of the steps described, and certain steps may be performed in other orders or concurrently without conflict.

As can be seen from the above, the method for screen projection of the device provided in the embodiments of the present application receives a screen projection request sent by a sending end using ultrasonic waves as an information carrier; acquiring first ultrasonic information carried by the screen throwing request according to the screen throwing request, and judging whether the sending end and the receiving end are in the same space or not based on the first ultrasonic information; and if the sending end and the receiving end are in the same space, sending second ultrasonic information containing the distribution network parameters to the sending end so that the sending end performs screen throwing operation after establishing a data transmission channel with the receiving end according to the distribution network parameters. By introducing the ultrasonic technology and utilizing the characteristic that ultrasonic waves can carry information, the equipment screen projection method can realize that the sending end sends information to the receiving end in an unconnected state, and meanwhile, energy loss can exist in the process of penetrating through an obstacle by utilizing ultrasonic waves, so that whether the sending end and the receiving end of a screen projection request are in the same space or not can be judged, and after the fact that the sending end and the receiving end are in the same space is determined, complicated operations such as manual networking and screen projection code input of a user can be skipped, and an automatic flow is changed.

As shown in fig. 6, the terminal device 1200 may include an RF (Radio Frequency) circuit 110, a memory 120 including one or more (only one is shown in the figure) computer readable storage mediums, an input unit 130, a display unit 140, a sensor 150, an audio circuit 160, a transmission module 170, a processor 180 including one or more (only one is shown in the figure) processing cores, and a power supply 190. It will be appreciated by those skilled in the art that the configuration of the terminal device 1200 shown in fig. 6 does not constitute a limitation of the terminal device 1200, and may include more or fewer components than shown, or may combine certain components, or may have a different arrangement of components. Wherein:

the RF circuit 110 is configured to receive and transmit electromagnetic waves, and to perform mutual conversion between the electromagnetic waves and the electrical signals, so as to communicate with a communication network or other devices. RF circuitry 110 may include various existing circuit elements for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption/decryption chip, a Subscriber Identity Module (SIM) card, memory, and the like. The RF circuitry 110 may communicate with various networks such as the internet, intranets, wireless networks, or other devices via wireless networks.

The memory 120 may be used to store software programs and modules, such as program instructions/modules corresponding to the device screen-throwing method in the above embodiment, and the processor 180 executes various functional applications and data processing by running the software programs and modules stored in the memory 120, so that the device screen-throwing can be performed by automatically selecting a vibration reminding mode according to the current scene where the terminal device is located, which not only can ensure that the scenes such as a conference are not disturbed, but also can ensure that the user can perceive an incoming call, and the intelligence of the terminal device is improved. Memory 120 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, memory 120 may further include memory remotely located relative to processor 180, which may be connected to terminal device 1200 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The input unit 130 may be used to receive input numeric or character information and to generate keyboard, mouse, joystick, optical or trackball signal inputs related to user settings and function control. In particular, the input unit 130 may comprise a touch sensitive surface 131 and other input devices 132. The touch sensitive surface 131, also referred to as a touch display screen or touch pad, may collect touch operations thereon or thereabout by a user (e.g., operations of the user on the touch sensitive surface 131 or thereabout by any suitable object or accessory such as a finger, stylus, etc.), and actuate the corresponding connection means according to a pre-set program. Alternatively, the touch sensitive surface 131 may comprise two parts, a touch detection device and a touch controller. The touch control detection device detects the touch control direction of a user, detects signals brought by touch control operation and transmits the signals to the touch control controller; the touch controller receives touch information from the touch detection device, converts the touch information into touch coordinates, sends the touch coordinates to the processor 180, and can receive and execute commands sent by the processor 180. In addition, the touch-sensitive surface 131 may be implemented in various types of resistive, capacitive, infrared, surface acoustic wave, and the like. In addition to the touch-sensitive surface 131, the input unit 130 may also comprise other input devices 132. In particular, other input devices 132 may include, but are not limited to, one or more of a physical keyboard, function keys (e.g., volume control keys, switch keys, etc.), a trackball, mouse, joystick, etc.

The display unit 140 may be used to display information input by a user or information provided to the user and various graphical user interfaces of the terminal device 1200, which may be composed of graphics, text, icons, video, and any combination thereof. The display unit 140 may include a display panel 141, and alternatively, the display panel 141 may be configured in the form of an LCD (Liquid Crystal Display ), an OLED (Organic Light-Emitting Diode), or the like. Further, the touch-sensitive surface 131 may cover the display panel 141, and after the touch-sensitive surface 131 detects a touch operation thereon or thereabout, the touch-sensitive surface is transferred to the processor 180 to determine a type of touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of touch event. Although in fig. 6 the touch-sensitive surface 131 and the display panel 141 are implemented as two separate components for input and output functions, in some embodiments the touch-sensitive surface 131 may be integrated with the display panel 141 to implement the input and output functions.

The terminal device 1200 may also include at least one sensor 150, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 141 according to the brightness of ambient light, and a proximity sensor that may turn off the display panel 141 and/or the backlight when the terminal device 1200 moves to the ear. As one of the motion sensors, the gravity acceleration sensor can detect the acceleration in all directions (generally three axes), and can detect the gravity and the direction when the mobile phone is stationary, and can be used for applications of recognizing the gesture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and knocking), and the like; other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc. that may also be configured with the terminal device 1200 are not described in detail herein.

Audio circuitry 160, speaker 161, microphone 162 may provide an audio interface between a user and terminal device 1200. The audio circuit 160 may transmit the received electrical signal converted from audio data to the speaker 161, and the electrical signal is converted into a sound signal by the speaker 161 to be output; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, receives the electrical signal from the audio circuit 160, converts the electrical signal into audio data, outputs the audio data to the processor 180 for processing, transmits the audio data to, for example, another terminal via the RF circuit 110, or outputs the audio data to the memory 120 for further processing. Audio circuitry 160 may also include an ear bud jack to provide communication of the peripheral headphones with terminal device 1200.

Terminal device 1200 may facilitate user email, web browsing, streaming media access, etc. via a transmission module 170 (e.g., wi-Fi module) that provides wireless broadband internet access to the user. Although fig. 6 shows the transmission module 170, it is understood that it does not belong to the essential constitution of the terminal device 1200, and may be omitted entirely as needed within the scope of not changing the essence of the invention.

The processor 180 is a control center of the terminal device 1200, connects various parts of the entire mobile phone using various interfaces and lines, and performs various functions of the terminal device 1200 and processes data by running or executing software programs and/or modules stored in the memory 120, and calling data stored in the memory 120, thereby performing overall monitoring of the mobile phone. Optionally, the processor 180 may include one or more processing cores; in some embodiments, the processor 180 may integrate an application processor that primarily processes operating systems, user interfaces, applications, etc., with a modem processor that primarily processes wireless communications.
