The following description is given to enable any person skilled in the art to make and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art will recognize that the invention can be practiced without these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of the invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0058] The embodiments of the present application provide a device connection method, system, apparatus, device, and computer-readable storage medium, which are described in detail below.

[0059] The device connection method in an embodiment of the present invention is applied to a device connection device, which is arranged on a device to be connected. The device is provided with one or more processors, memories, and one or more applications, wherein the one or more applications are stored in the memories and configured to be executed by the processor to implement the device connection method; the device can be a terminal, such as a mobile phone or a tablet computer, or the device can be a server, or a service cluster consisting of multiple servers.

[0060] like Figure 1 As shown, Figure 1 This is a scenario diagram of the device connection method in an embodiment of the present application. The device connection scenario in the embodiment of the present invention includes a device 100 (a device connection device is integrated in the device 100), and a computer-readable storage medium corresponding to the device connection is run in the device 100 to execute the steps in the device connection method.

[0061] It is understandable that Figure 1 The devices in the scenario of the device connection method shown, or the devices included in the devices, do not constitute a limitation on the embodiments of the present invention. That is, the number of devices and types of devices included in the scenario of the device connection method, or the number and types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiments of the present invention.

[0062] In the embodiment of the present invention, the device 100 is mainly used to: assign a first graphic identifier to the projected screen device; receive broadcast information sent by the projected screen device, and generate a graphic identifier page according to the first graphic identifier corresponding to the broadcast information; in response to a trigger operation on the graphic identifier page, determine the target graphic identifier corresponding to the trigger operation, and the target projected screen device corresponding to the target graphic identifier; if there are at least two target projected screen devices, assign a second graphic identifier to the target projected screen device, until there is a target projected screen device, and create a connection with the target projected screen device.

[0063] In the embodiment of the present invention, the device 100 may be an independent device. For example, the device 100 may be a screen projection device. Optionally, the device 100 may be a server. The server may be an independent server or a server network or server cluster composed of servers, including but not limited to a computer, a network host, a single network server, a set of multiple network servers, or a cloud server composed of multiple servers. The cloud server is composed of a large number of computers or network servers based on cloud computing.

[0064] Those skilled in the art will understand that Figure 1The application environment shown in the figure is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or fewer devices shown in , or device network connection relationships, such as Figure 1 Only one device is shown. It can be understood that the scenario of the device connection method can also include one or more other devices, which are not limited here. The device 100 can also include a memory for storing data, for example, storing graphic information obtained by shooting.

[0065] In addition, in the scenario of the device connection method of the present application, the device 100 can be provided with a display device 200, or the device 100 is not provided with a display device and is in communication connection with an external display device. The display device 200 is used to output the result of the execution of the device connection method in the device, for example, to display a graphic identification page for user operation. The device 100 can access a backend database 300 (the backend database can be in the local memory of the device, or the backend database can also be set in the cloud), and the backend database 300 stores information related to the device connection, for example, the initial graphic in the backend database 300, or pre-set filtering parameters.

[0066] It should be noted that Figure 1 The schematic diagram of the device connection method scenario shown is only an example. The scenario of the device connection method described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0067] Based on the scenario of the above device connection method, an embodiment of the device connection method is proposed.

[0068] like Figure 2 FIG. 2 is a flow chart of an embodiment of a device connection method in an embodiment of the present application, wherein the device connection method includes steps S201-S204:

[0069] S201. Allocate a first graphic identifier to the projected screen device.

[0070] Among them, the projected screen device, that is, the device that can be connected for screen projection, can be, for example, a conference tablet, a large screen in a conference room, etc.

[0071] Among them, the specific graphic shape of the first graphic identifier is not specifically limited in this application. For example, the first graphic identifier may include a triangle, a circle, a pentagon, etc. It is understandable that there may be multiple projected devices. By assigning first graphic identifiers of different shapes to different projected devices for display, different projected devices can be identified so that the user can determine which one I want to connect to.

[0072] For example, in one embodiment of the present application, there are 255 projected devices and five graphic identifiers to be assigned. Each graphic identifier can be assigned as a first graphic identifier to 51 projected devices, that is, one first graphic identifier corresponds to multiple projected devices.

[0073] For example, in another embodiment of the present application, it may also include 5 projected devices and five graphic identifiers to be assigned. Each graphic identifier can be assigned as a first graphic identifier to one projected device, that is, one first graphic identifier corresponds to one projected device.

[0074] Furthermore, the triggering conditions for allocating the first graphic identifier to the screen projection device are not specifically limited in this application, but are exemplified as follows:

[0075] In one of the embodiments of the present application, the device connection method is applied to a screen projection device, and the screen projection device triggers the allocation of a first graphic identifier to the projected device when screen projection is required. For example, the user opens the screen projection client to trigger the allocation of a first graphic identifier to the projected device, or the user clicks the screen projection connection button of the screen projection client to trigger the allocation of a first graphic identifier to the projected device.

[0076] In another embodiment of the present application, the device connection method is applied to the server. When the server detects that any device being projected is online, it triggers the allocation of a first graphic identifier for the device being projected.

[0077] S202. Receive the broadcast information sent by the screen-projected device, and generate a graphic identification page according to the first graphic identification corresponding to the broadcast information.

[0078] Among them, the broadcast information is a Bluetooth message sent through a Bluetooth channel. Each Bluetooth message carries the first graphic identifier of the projected device that sends the Bluetooth message. In some implementation schemes, the Bluetooth message also includes the device address information of the corresponding projected device. The device address information is such as: device IP, including the device connection code of the device IP, etc.

[0079] Wherein, the graphic identification page includes one or more operable first graphic identification components, for example, see Figure 3 The first graphic identification includes a circle, a square, a triangle, a diamond, and a star, and the first graphic identification components include a circle component, a square component, a triangle component, a diamond component, and a star component, that is, an operable first graphic identification component is a component corresponding to a gray area, and each component is displayed with a corresponding first graphic identification.

[0080] Specifically, after receiving the broadcast information sent by the projected screen device, the first graphic identifier carried by each broadcast information is extracted, and a graphic identifier page is generated based on the first graphic identifier. It can be understood that since one first graphic identifier may correspond to multiple different projected screen devices, that is, multiple broadcast information carrying the same first graphic identifier may be received, after receiving multiple broadcast information, the first graphic identifier carried by each broadcast information can be extracted, and different first graphic identifiers that have appeared can be selected to generate a graphic identifier page. For example, if multiple broadcast information carry circles, any circle is extracted to generate an operable first graphic identifier component corresponding to the circle.

[0081] S203. In response to a triggering operation on the graphic identification page, determine a target graphic identification corresponding to the triggering operation and a target screen projection device corresponding to the target graphic identification.

[0082] The trigger operation may include an operation based on a mouse or a touch screen for any operable first graphic identification component in the graphic identification page, for example, the trigger operation includes at least one of single-click, double-click, long press and other operations.

[0083] Wherein, the target graphic identifier is any one of the first graphic identifiers.

[0084] Illustratively, in one embodiment of the present application, the screen projection device includes a touch-sensitive display screen, and the graphic identification page is displayed to the user through the touch-sensitive screen. The user operates any first graphic identification component in the graphic identification page through the touch-sensitive screen to receive the trigger operation. Furthermore, after receiving the trigger operation on the graphic identification page, the trigger operation on the graphic identification page is responded to, and the first graphic identification component corresponding to the trigger operation is determined, and then the target graphic identification corresponding to the first graphic identification component is determined. Furthermore, after determining the target graphic identification, the allocation of the target graphic identification is searched, and then the target screen projection device corresponding to the target graphic identification is determined.

[0085] S204: If there are at least two target screen-projected devices, assign a second graphic identifier to the target screen-projected devices until there is a target screen-projected device, and then create a connection with the target screen-projected device.

[0086] Among them, the second graphic identifier is at least two of the first graphics. It can be understood that when there are at least two target screen-projected devices, the first graphic identifier is further allocated to each target screen-projected device.

[0087] Specifically, after determining the target projected screen device corresponding to the target graphic identifier, if there are at least two target projected screen devices, that is, the target graphic identifier is assigned to at least two projected screen devices, then in order to further determine which device the user is to connect to, a second graphic identifier is further assigned to the target projected screen device to control the target projected screen device to display the first graphic identifier and the second graphic identifier at the same time. Furthermore, the user re-inputs a trigger operation based on the graphic identifier page in combination with the second graphic identifier displayed on the target projected screen device, and then further narrows the range of target projected screen devices according to the trigger until a screen transmission connection is created between the projection device and the target projected screen device.

[0088] It can be further understood that if there are at least two target screen projection devices, a second graphic identifier is assigned to the target screen projection device until there is a target screen projection device, and a connection with the target screen projection device is established, specifically including the steps of:

[0089] (1) receiving a first trigger operation from a user based on a graphic identification page, and determining a target graphic identification corresponding to the first trigger operation;

[0090] (2) If the target graphic identifier corresponding to the first operation information corresponds to a target screen projection device, establishing a connection with the target screen projection device;

[0091] (3) If the target graphic identifier corresponds to at least two target screen-projected devices, assigning a second graphic identifier to the target screen-projected devices, wherein the second graphic identifier is at least two of the first graphic identifiers;

[0092] (4) controlling the secondary graphic identifier on the target screen projection device, receiving the second operation information of the user based on the graphic identifier page, and determining the target device graphic identifier corresponding to the second operation information;

[0093] (5) If the target graphic identifier corresponding to the second operation information corresponds to a target screen projection device, establishing a connection with the target screen projection device;

[0094] Further, it can be understood that if the target graphic identifier corresponding to the second operation information corresponds to at least two target projected devices, a third graphic identifier is assigned to the target projected device, wherein the third graphic identifier is at least two of the first graphic identifiers; the target projected devices are further screened until there is a target projected device, and a connection is created with the target projected device. The specific number of iterations is determined according to the number of target projected devices, and this application does not make any specific limitations.

[0095] For example, see Figure 4 , Figure 4 This is a diagram of the interface changes corresponding to the graphic identification page during the process of determining the target screen being projected in the implementation plan of this application.

[0096] Specifically, the conference tablet is the screen-projected device to be connected by the user among all the screen-projected devices, and the screen transmission sending end is the screen-projecting device. Specifically, the server assigns a first graphic identifier to each screen-projected device, and the conference tablet controls the display of the first graphic identifier (circle) after receiving the assigned first graphic identifier (see Figure 4-1 ), and the hotspot beacon of the conference tablet broadcasts the device IP information and the first graphic identifier externally; at the same time, the screen transmission end receives the first graphic identifier broadcast by each screen-cast device (including the conference tablet), and generates a corresponding graphic identifier page display according to the first graphic identifier (see Figure 4-2 ); further, the user performs a trigger operation based on the graphic identification page, and the screen transmission end (screen transmission device) controls the graphic identification page to display changes according to the trigger operation, and generates a target graphic identification display area for displaying the target image identification corresponding to the trigger operation (see Figure 4-3 ), wherein the target image identifier is a circle; further, determining the target projection device corresponding to the target graphic identifier, if there are at least two target projection devices, assigning a second graphic identifier to the target projection device, and further sending the second graphic identifier to the conference tablet for display (see Figure 4-4 ); Further, after seeing the second graphic logo displayed on the conference flat panel, the user further inputs a trigger operation (second trigger operation) on the graphic logo page of the screen transmission end, that is, further selects the corresponding target graphic logo, and the target graphic logo display area is used to display the target image logo corresponding to the trigger operation (see Figure 4-5 ), further, determine the target screen projection device corresponding to the target graphic identifier (corresponding to the second trigger operation), if there are at least two target screen projection devices, assign a third graphic identifier to the target screen projection device, and further send the third graphic identifier to the conference tablet for display (see Figure 4-6 ); Further, after seeing the third graphic logo displayed on the conference flat panel, the user further inputs a trigger operation (third trigger operation) on the graphic logo page of the screen transmission end, that is, further selects the corresponding target graphic logo. If it is determined that the target graphic logo corresponds to a target screen projection device, the target graphic logo display area is used to display the target graphic logo corresponding to the trigger operation and the connection button (see Figure 4-7), further, the user can feedback the connection request to the server by clicking the connection button, and the server creates a screen transmission connection between the target screen-projected device and the screen-projecting device; it can be understood that in some other implementation schemes of the present application, if it is determined that the target image identifier corresponds to a target screen-projected device, then the target graphic identifier display area is used to display the target image identifier corresponding to the trigger operation, and automatically create a screen transmission connection between the target screen-projected device and the screen-projecting device, which is not limited to this specific application.

[0097] Further, based on the above implementation scheme, see Figure 5 , Figure 5 This is a flow chart of one implementation scheme for generating a graphic identification page in the device connection method provided in an embodiment of the present application, specifically including steps S501-S502:

[0098] S501: Receive broadcast information sent by the screen projection device.

[0099] Specifically, in this embodiment, the projection device sends a connection request to the server, the server controls each projected device to send broadcast information, and the projection device receives the broadcast information.

[0100] It is understandable that in some other embodiments of the present application, the projected device may also continue to send broadcast information (or continue within a preset time period) after being assigned to the first graphic identifier, and the projecting device may receive the broadcast information sent by the projected device at any time.

[0101] S502: Sort the first graphic identifiers corresponding to the broadcast information according to the signal strength corresponding to the broadcast information to form a graphic identifier page.

[0102] Specifically, in this embodiment, after receiving the broadcast information sent by each projected device, the screen projection device extracts non-repetitive first graphic logos from the broadcast information in turn according to the signal strength corresponding to each broadcast information and sorts them according to the extraction order, and fills the first graphic logos into the editable components in the preset graphic logo page template in turn to form a graphic logo page.

[0103] Further, based on the above implementation scheme, see Figure 6 , Figure 6 This is a flow chart of one implementation scheme of the device connection method provided in an embodiment of the present application, specifically including steps S601-S606:

[0104] S601: Allocate a first graphic identifier to the screen-projected device;

[0105] S602: Receive broadcast information sent by the screen-projected device, and generate a graphic identification page according to the first graphic identification corresponding to the broadcast information;

[0106] S603: In response to a triggering operation on the graphic identification page, determining a target graphic identification corresponding to the triggering operation and a target screen projection device corresponding to the target graphic identification;

[0107] S604: If there are at least two target screen-projected devices, assign a second graphic identifier to the target screen-projected devices until there is one target screen-projected device.

[0108] The specific implementation of steps S601-S604 may refer to any of the above implementation schemes.

[0109] S605. If the target screen-projected device is in a communication state, obtain the first device priority of the communication device that communicates with the target screen-projected device.

[0110] The target screen projection device is in a communication state, that is, the target screen projection device is in a screen transmission connection with other screen projection devices. In other words, the communication device is another screen projection device.

[0111] Exemplarily, the device priority (including device priority) can be set or updated according to the user information corresponding to the projection device or the number of projection connections of the projection device, which is not limited in this application.

[0112] Specifically, after determining that there is only one target screen projection device, check the screen projection connection status of the target screen projection device. If the target screen projection device is in a communication state, further obtain the first device priority of the communication device communicating with the target screen projection device.

[0113] S606. If the first device priority is less than or equal to the second device priority, control the target screen projection device to disconnect the communication connection and establish a connection with the target screen projection device.

[0114] The second device priority is the device priority of the screen projection device to be connected to the target screen projection device. The device to be connected is, that is, the screen projection device that displays the graphic identification page.

[0115] Specifically, after obtaining the first device priority of the communication device that communicates with the target screen-projected device, the second device priority is further obtained, and the second device priority is compared with the first device priority. If the first device priority is less than or equal to the second device priority, the target screen-projected device is first controlled to disconnect the screen transmission communication connection with the communication device, and create a connection between the device to be connected and the target screen-projected device.

[0116] Furthermore, in some other implementation schemes of the present application, after comparing the second device priority with the device priority, if the first device priority is greater than the second device priority, it means that the communication device is connected first, then the target screen-projected device is controlled to maintain the screen communication connection with the communication device, and the connection status of the target screen-projected device is fed back. For example, it can be through display feedback or voice feedback. The specific feedback method is not specifically limited in this application.

[0117] Furthermore, based on the above implementation scheme, the present application also provides another implementation scheme of a device connection method, which specifically includes the steps of:

[0118] (1) In response to a connection request sent by the screen-projected device, if there are at least two screen-projected devices, assigning a first graphic identifier corresponding to the third device priority to each of the screen-projected devices;

[0119] Exemplarily, the connection request can automatically trigger the projection device to send a connection request to the matching server after any projection device is connected to the router. After receiving the connection request from the projection device, the server obtains the number of projection devices connected to the router through the system interface, and obtains the first graphic identifier corresponding to the third device priority assigned to each projection device, thereby realizing the allocation of graphic identifiers to the projection devices.

[0120] (2) receiving broadcast information sent by each of the screen-projected devices, and obtaining the first graphic identifier corresponding to the broadcast information and the third device priority corresponding to the first graphic identifier;

[0121] (3) Sort the first graphic identifiers according to the third device priority corresponding to the first graphic identifiers, and generate a graphic identifier page.

[0122] Specifically, each projected screen device generates and sends a broadcast message based on its corresponding device priority and the assigned first graphic identifier. The screen-projecting device receives the broadcast message sent by the projected screen device, obtains the first graphic identifier corresponding to the broadcast message, and the third device priority corresponding to the first graphic identifier, sorts the first graphic identifiers according to the device priority, and generates a graphic identifier page.

[0123] (4) in response to a triggering operation on the graphic identification page, determining a target graphic identification corresponding to the triggering operation and a target screen projection device corresponding to the target graphic identification;

[0124] (5) If there are at least two target screen-projected devices, a second graphic identifier is assigned to the target screen-projected devices until there is a target screen-projected device, and a connection is established with the target screen-projected device.

[0125] Further, based on the above implementation scheme, see Figure 7 , Figure 7 This is a flow chart of one implementation scheme for connection creation in the device connection method provided in an embodiment of the present application, specifically including steps S701-S702:

[0126] S701: Acquire first device address information in the broadcast information and second device address information corresponding to the trigger operation.

[0127] Among them, the second device address information, that is, the projection device that displays the graphic identification page mentioned in the above implementation scheme for the user to input a trigger operation, the second device address information is the device IP address of the projection device, or a connection code including the device IP address.

[0128] Specifically, in the implementation scheme of the present application, after the projected screen device is assigned to the first graphic identifier, the device address information of the projected screen device is further packaged into the broadcast information. After the connected device determines the target projected screen device, it parses the broadcast information sent by the target projected screen device, that is, obtains the first device address information carried in the broadcast information, and the second device address information corresponding to the trigger operation.

[0129] S702. Create a screen transmission connection between the target screen-projected device and the screen-projecting device corresponding to the second device address information according to the first device address information and the second device address information.

[0130] Furthermore, after obtaining the first device address information and the second device address information, a screen transmission connection is created between the projection device corresponding to the trigger operation and the target projection device through the address information. For example, the first device address information is sent to the projection device, and the projection device sends the second device address information and the projection request to the target projection device. The target projection device responds to the projection request and verifies it according to the second device address information. Further, the projection device and the target projection device transmit projection data according to the first device address information and the second device address information.

[0131] Furthermore, based on the above implementation scheme, the present application also provides another implementation scheme of a device connection method, which specifically includes the steps of:

[0132] (1) Allocating a first graphic identifier to the projected device;

[0133] (2) receiving broadcast information sent by the screen projection device, and generating a graphic identification page according to the first graphic identification corresponding to the broadcast information;

[0134] (3) in response to a triggering operation on the graphic identification page, determining a target graphic identification corresponding to the triggering operation and a target screen projection device corresponding to the target graphic identification;

[0135] (4) If there are at least two target screen-projected devices, a second graphic identifier is assigned to the target screen-projected devices until there is a target screen-projected device, and a connection is established with the target screen-projected device.

[0136] Specifically, the above steps refer to any of the above implementation plans.

[0137] (5) In response to the connection lock request of the target screen projection device, the device graphic identifier of the target screen projection device is set to an invalid state.

[0138] Among them, the connection lock request is used to control the screen projection connection lock between the target screen projection device and the above-mentioned device to be connected, that is, the target screen projection device does not receive connections from other devices during the screen projection connection with the above-mentioned device to be connected.

[0139] It can be understood that the connection lock request can be triggered by device priority or by user operation. For example, after creating a screen casting connection between the target screen-projected device and the above-mentioned device to be connected, if the device priority of the device to be connected is greater than the preset priority threshold, a connection lock request is triggered.

[0140] (6) Control the target projection device to stop sending broadcast information.

[0141] Specifically, in one of the implementation schemes of the present application, after receiving the connection lock request, the server responds to the connection lock request of the target projected device and sets the device graphic identifier of the target projected device to an invalid state. For example, the first graphic identifier of the target projected device is marked with an invalid label so that when other devices subsequently perform screen projection connections, the target projected device can be filtered out according to the invalid label; further, the target projected device is controlled to stop sending broadcast information to avoid other devices receiving the broadcast information sent by the target projected device when other devices subsequently perform screen projection connections. The accuracy of the connection lock of the target projected device is achieved through the dual guarantee of setting the device label invalid and stopping the sending of broadcast information.

[0142] In the implementation scheme of the present application, screen projection connection is achieved by allocating graphics, and the connection operation is completed intuitively and quickly. Generally, the screen transmission connection can be completed directly by clicking once / twice on the pattern (the user inputs the trigger operation based on the graphic identification page) without entering a multi-digit screen transmission code; in addition, compared with the prior art that connects by device name, graphical devices are easier to identify and distinguish, and can be quickly identified and connected through intuitive circular and triangular symbols; and compared with the six- or seven-digit screen transmission code and the more than ten-digit device name, this solution only needs a single-digit graphic symbol to meet the connection requirements, occupying very low screen occlusion, and at the same time, the graphical symbols are compared with alphanumeric characters, because the graphics themselves do not contain readable information like letter symbols, and are less likely to cause disturbance to users.

[0143] The implementation scheme of the present application provides a device connection method, which assigns a first graphic identifier to the projected device; and receives broadcast information sent by the projected device, and generates a graphic identifier page according to the first graphic identifier corresponding to the broadcast information; further responds to a trigger operation on the graphic identifier page, determines the target graphic identifier corresponding to the trigger operation, and the target projected device corresponding to the target graphic identifier; if there are at least two target projected devices, assigns a second graphic identifier to the target projected device, until there is a target projected device, and creates a connection with the target projected device. This solution assigns a first graphic identifier to the projected device and receives broadcast information sent by the projected device, and generates a graphic identifier page according to the first graphic identifier corresponding to the broadcast information, so that the user can determine the corresponding target graphic identifier by inputting a trigger operation based on the graphic identifier page, and further assigns a secondary graphic identifier to the projected device for distinction and limitation when there are multiple target projected devices corresponding to the target graphic identifier, so that the user can further screen the devices based on the graphic identifier page, and then determine the target projected device corresponding to the target graphic identifier, avoiding the disadvantages of entering cumbersome connection information and the need to frequently switch input methods. The user can determine the corresponding target projected device based on the graphic identifier page operation to achieve connection with the target projected device, simplifying the connection process between the screen transmitting devices and improving the convenience of connecting the screen transmitting devices.

[0144] Furthermore, in one implementation scenario of the present application, the device connection method is applied to a device connection system, the device connection system comprising: a projected screen device and a projecting screen device in communication connection, the device connection system being configured to perform the following steps:

[0148] The projection device is used to determine the target graphic identifier corresponding to the trigger operation and the target projected device corresponding to the target graphic identifier in response to the trigger operation of the graphic identifier page; if there are at least two target projected devices, a second graphic identifier is assigned to the target projected device until there is a target projected device, and a connection is created between the projection device and the target projected device.

[0149] Furthermore, in another implementation scenario of the present application, the device connection method is applied to a device connection system, the device connection system comprising: a communicatively connected server, a projected device, and a projecting device, the device connection system being used to perform the following steps:

[0150] The server is configured to allocate a first graphic identifier to the screen-projected device;
