[0026] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0027] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0028] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0029] In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0030] Figure 1 The following is an example of an application scenario of the device connection method applicable to the embodiment of the present application. Figure 1 .like Figure 1 As shown, the application scenario includes: a first device 11 and at least one second device 12; wherein the first device 11 may be a smart terminal, a personal computer (PC), and the second device 12 may be an audio device.

[0031] In some scenarios, the first device 11 may also be a smart interactive tablet, and the second device 12 may also be a speaker.

[0032] Among them, the hardware part of the smart interactive tablet is composed of a touch display module, an intelligent processing system (including a controller) and other parts, which are combined together by overall structural parts and are also supported by a dedicated software system. The touch display module includes a display screen, a touch component and a backlight component. The backlight component is used to provide a backlight source for the display screen. The display screen generally uses a liquid crystal display device for displaying pictures. The touch component is set on the display screen or at the front end of the display screen to collect the user's touch operation data and send the collected touch operation data to the intelligent processing system for processing.

[0033] In actual use, the screen data is displayed on the display screen of the smart interactive tablet. When the user clicks on the content displayed on the display screen with a touch object such as a finger or a stylus, for example, clicks on a graphic button displayed on the display screen, the touch component of the smart interactive tablet will collect the touch data, and the touch component will convert the touch data into coordinate data of the touch point and send it to the intelligent processing system, or send it to the intelligent processing system and convert it into coordinate data of the touch point by the intelligent processing system. After the intelligent processing system obtains the coordinate data of the touch point, it implements the corresponding control operation according to the pre-set program, drives the display content of the display screen to change, and realizes a variety of display and operation effects.

[0034] Touch components can be divided into five basic categories based on technical principles: vector pressure sensing technology touch components, resistance technology touch components, capacitance technology touch components, electromagnetic technology touch screens, infrared technology touch components, and surface acoustic wave technology touch components. According to the working principle of the touch component and the medium for transmitting information, the touch component can be divided into four categories: resistance, capacitance induction, electromagnetic induction, infrared, and surface acoustic wave.

[0035] When the user touches the display screen with a finger or a pen, the touch component can collect data from the touch point and send it to the intelligent processing system, and then use the built-in software of the intelligent processing system to implement different functional applications, thereby realizing touch control of the intelligent processing system.

[0036] The “screen” and “large screen” mentioned in this application refer to the display screen of the smart interactive tablet; the smart interactive tablet displaying a certain interface means that the display screen of the smart interactive tablet displays the interface.

[0037] Smart interactive tablets are integrated devices that use touch technology to control the content displayed on display tablets (LCD, LED, PDP) and realize human-computer interaction. Smart interactive tablets can build a system with central consoles, cameras, computers, speakers, microphones and other devices to achieve more functions.

[0038] Taking the teaching scenario as an example, teachers can teach through smart interactive tablets; in addition, teachers can also connect smart interactive tablets with teaching electronic devices such as speakers and microphones to achieve diversified teaching. There are many teaching electronic devices in school classrooms, and each device is independent of each other. To achieve interconnection between devices, it is necessary to first deploy and install these devices, and then connect these devices. Taking the connection between these devices via Bluetooth as an example, the operator needs to turn on the discovery and pairing functions of each electronic device in turn, so that other electronic devices can be searched. After other electronic devices search for surrounding electronic devices, the operator needs to manually confirm the electronic devices that need to be connected again. The above process is repeated many times to complete the adaptation connection of each electronic device. When the number of devices is large, the device needs to be searched and confirmed one by one during the adaptation connection process, which makes the device connection efficiency low; in addition, during the search process, the smart interactive tablet may search for multiple devices around. At this time, it is necessary to manually screen out the devices that the smart interactive tablet currently needs to connect to, and then manually connect. In this way, there may be problems with misconnection.

[0039] In response to the above technical problems, the inventors of the present application propose the following technical concept: in some scenarios where the first device is used, the type of the second device that the first device needs to connect to is usually a fixed type. The fixed type can be one type or multiple types. In each device connection process, the first device usually establishes a wireless connection with one type of the second device. Therefore, if the first device stores the identifier of the second device that has established a wireless connection with the first device, it can automatically reconnect to the second device. In order to avoid the situation where the connection fails when the first device actively reconnects to the second device when the second device is in a hidden state. The first device can also send a trigger message to the second device to trigger the second device to automatically reconnect to the first device.

[0040] The technical solution of the present invention and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0041] based on Figure 1 The scene shown, Figure 2Interaction of the device connection method provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the device connection method of this embodiment includes the following steps:

[0042] Step S201: Determine whether the first device stores an identifier of a device of the target type.

[0043] The execution subject of this step may be the first device.

[0044] Taking the application of smart interactive tablet in teaching scenario as an example, the target type of device can be a speaker. For speakers that have established wireless connection with the smart interactive tablet and speakers that have not established wireless connection with the smart interactive tablet, they all belong to the same target type of device.

[0045] In this embodiment, determining whether the first device stores the identifier of the target type of device is intended to determine whether the first device has established a wireless connection with the target type of device. If the first device has established a wireless connection with the target type of device, the first device stores the identifier of the target type of device. Based on the identifier of the device stored in the first device, it can be determined whether the first device has established a wireless connection with the target type of device.

[0046] Step S202: If the first device stores an identifier of a device of the target type, the first device sends trigger information to the second device, where the trigger information is used to instruct the second device to send a connection request. The type of the second device is the target type, and the second device is connected to the first device via a line input line.

[0047] In this embodiment, the first device and the second device can transmit audio through a line-in connection, or can also transmit data through low-power wireless communication technology. This embodiment aims to wirelessly connect the first device and the second device.

[0048] In this embodiment, the second device may be in a hidden state or in a discoverable state. Therefore, in order to avoid the situation where the second device is in a hidden state, the first device sends a connection request to the second device, but the second device cannot receive it, resulting in a connection failure. In this embodiment, the second device can be connected to the first device through a link method such as a line in line, so that when the second device and the first device have not established a wireless connection, the first device sends trigger information to the second device through the line in line to trigger the second device to actively connect back to the first device.

[0049] In some embodiments, the trigger information may be preset audio information. Still taking the smart interactive tablet and the speaker as an example, the smart interactive tablet is provided with a line out interface, and the speaker is provided with a line in interface. The line out interface of the smart interactive tablet is connected to the line in interface provided on the speaker through a line in line, so that the transmission of the trigger information can be realized.

[0050] Among them, the second device sends a connection request to the first device by means of directional broadcast. Therefore, the role of the trigger information can be understood as triggering the directional broadcast function of the second device, so that the second device sends a connection request to the first device by means of directional broadcast. For the specific implementation of directional broadcast, please refer to the introduction of related technologies, which will not be repeated in this embodiment.

[0051] Step S203: The second device receives trigger information.

[0052] Step S204: The second device sends a connection request to the first device according to the trigger information.

[0053] The second device sends a connection request to the first device by way of directional broadcast.

[0054] Step S205: The first device receives a connection request sent by the second device.

[0055] Step S206: The first device establishes a wireless connection with the second device according to the connection request.

[0056] In this embodiment, the connection request sent by the second device includes the connection information of the second device. The first device receives the connection request sent by the second device and establishes a wireless connection with the first device according to the connection information of the second device in the connection request. For the specific content of the connection information, please refer to the introduction of the related technology, which will not be repeated here.

[0057] In some embodiments, after the first device establishes a wireless connection with the second device, the state of the second device can be obtained, and the second device can be controlled according to the state of the second device.

[0058] The device connection method provided in this embodiment determines whether the identifier of the target type of device is stored in the first device, and if the identifier of the target type of device is stored in the first device, trigger information is sent to the second device through the line input line, and the trigger information is used to instruct the second device to send a connection request, the type of the second device is the target type, and according to the connection request sent by the second device, a wireless connection is established with the second device. In this scheme, since it is first determined whether the identifier of the target type of device is stored in the first device, and when it is determined that the identifier of the target type of device is stored in the first device, the second device is triggered to send a connection request to the first device, so as to achieve a back connection with the second device, the above process does not require manual operation, and can achieve automatic connection between the first device and the second device, so that the connection efficiency can be improved. In addition, the second device is connected to the first device through a linking method such as a line in line, so that when the second device and the first device do not establish a wireless connection, the first device can send a trigger information to the second device through the line in line to trigger the second device to actively connect back to the first device. It can avoid the situation where the second device is in a hidden state, the first device sends a connection request to the second device, and the second device cannot receive it, resulting in a connection failure.

[0059] Figure 3 Interaction of the device connection method provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, the device connection method may also include the following steps:

[0060] Step S207: If the first device does not store the identifier of the target type of device, the first device sends preset information to the second device, where the preset information is used to trigger the second device to start the discovery and pairing function.

[0061] The preset information may be preset audio information. It should be understood that the trigger information and the preset information are used to trigger different functions of the second device. In order to distinguish the trigger information from the preset information, the audio information corresponding to the trigger information and the preset information in this embodiment may be different audio information.

[0062] In some embodiments, the first device loads preset audio information and outputs it to the second device through the line out interface. The second device receives the preset audio information through the line in interface and identifies whether the received audio information is the preset audio information. If the received audio information is the preset audio information, it activates its own discovery and pairing functions.

[0063] Step S208: The second device receives preset information.

[0064] Step S209: The second device starts discovery and pairing functions.

[0065] Step S210: The first device establishes a wireless connection with the second device through the discovery and pairing functions of the second device.

[0066] In this embodiment, the second device receives the preset information and turns on its own discovery and pairing functions, wherein the discovery and pairing functions are used to enable the first device to discover the second device and pair with the second device, thereby establishing a wireless connection.

[0067] Specifically, after the first device sends the preset information, it can search for a device of the target type. If a device of the target type is found, a wireless connection is established with the searched device of the target type.

[0068] In this embodiment, when the identifier of the target type of device is not stored in the first device, the first device sends preset information to the second device to trigger the second device to start the discovery and pairing functions, thereby establishing a wireless connection with the second device. Since the first device sends preset information to the second device to trigger the second device to start the discovery and pairing functions when the identifier of the target type of device is not stored in the first device, it is possible to achieve automatic connection with the second device when the first device has not established a wireless connection with the target type of device.

[0069] On the basis of the above embodiment, in order to conveniently and quickly determine whether the second device stores the identifier of the target type of device. The first device may also establish a storage list for storing the identifiers of devices that establish a wireless connection with the first device. Specifically, after the first device establishes a wireless connection with the second device, the identifier of the second device that is connected this time may be stored in the storage list. The form of the storage list may be as shown in Table 1 below:

[0070] Identification of connected devices SS*1 SS*2 ……

[0071] In the above Table 1, SS*1 and SS*2 are identifiers of the same type of equipment.

[0072] Similarly, in the second device, a storage list may also be established to store the identifiers of the devices connected to the second device, so as to realize automatic reconnection next time.

[0073] Figure 4 This is a flow chart of a device connection method provided in an embodiment of the present application. Figure 4 As shown, in the device connection method, determining whether the first device stores an identifier of a device of the target type specifically includes the following steps:

[0074] Step S401: Obtain a storage list, where the storage list is used to store identifiers of devices that have established wireless connections with the first device.

[0075] Step S402: If the type indicated by the identifier of the device in the storage list is the target type, determine the identifier of the device of the target type stored in the first device.

[0076] Step S403: If the type indicated by the identifier of the device that does not exist in the storage list is the target type, it is determined that the identifier of the device of the target type is not stored in the first device.

[0077] It is understandable that in the initial stage, that is, the first device has not established a wireless connection with any device, the storage list is empty. In this case, the first device determines that the storage list is empty based on the storage list, and can determine that the identifier of the target type of device is not stored in the first device, that is, the first device has not established a wireless connection with the target type of device. At this time, the implementation method shown in steps S207 to S210 can be followed. After step S210 is executed, the first device stores the identifier of the second device in the storage list. Then, when the first device and the second device are connected next time, they can directly realize automatic reconnection according to the implementation method shown in steps S202 to S206.

[0078] For example, in a teaching scenario, a smart interactive tablet is usually connected to a speaker. For a smart interactive tablet, a speaker is a type of device, and all speakers are named according to the standard naming method. For example, speaker 1 is named "SS*1" and speaker 2 is named "SS*2". It can be understood that although SS*1 and SS*2 are names of different speakers, their prefixes "SS*" both represent the names of the speakers. Therefore, if it is detected that the identifier of the device in the storage list includes the "SS*" identifier, it means that the speaker has established a wireless connection with the smart interactive tablet. Then, all subsequent speakers can automatically reconnect to the smart interactive tablet.

[0079] On the basis of the above-mentioned implementation of automatic connection between the first device and the second device, in order to further ensure that the automatically connected device is the device to be connected, the present application can also propose the following embodiments. Specifically: after the second device establishes a wireless connection with the first device, the second device sets its own state to a hidden state.

[0080] In the hidden state, other devices cannot discover the second device. Then, the first device that needs to establish a wireless connection with the second device can send a trigger message to the second device through the line in line to trigger the second device to actively connect back to the first device. In this way, the defect that the device automatically connected during the adaptation and connection of the first device is not the device to be connected can be avoided. In addition, multiple second devices will not affect each other when they are adapted and connected at the same time. For example, there are smart interactive tablet 1 and speaker 1 in classroom 1, and there are smart interactive tablet 2 and speaker 2 in classroom 2. When the distance between classroom 1 and classroom 2 is very close, and speaker 1 and speaker 2 are both discoverable, smart interactive tablet 1 will search for speaker 1 and speaker 2 at the same time during the adaptation and connection process. If the status of speaker 1 and speaker 2 is hidden, the smart interactive tablet 1 will not search for speaker 1 and speaker 2. The smart interactive tablet 1 will search for speaker 1 and speaker 2 through Figure 2 The device connection method of the illustrated embodiment performs device connection with the speaker 1 without being affected by other unpaired or paired devices, thereby avoiding erroneous connection.

[0081] Figure 5 The following is an example of an application scenario of the device connection method applicable to the embodiment of the present application. Figure 2 .like Figure 5 As shown, the application scenario includes: a first device 51, at least one second device 52 and at least one third device 53; a third device 53 can be connected to at least one second device 52, and the third device 53 and the second device 52 are connected to each other through a high-real-time wireless communication technology, thereby realizing a low-latency wireless amplification function and data transmission communication. Optionally, the high-real-time wireless communication technology can adopt infrared communication technology.

This embodiment will not be described in detail here.

[0084] In this embodiment, the first device and the third device are independent of each other, and there is no direct communication method.

[0089] Step S603: The third device sends a second transfer message to the second device;

[0090] Step S604: The second device receives the second transfer message and forwards it to the first device.

[0091] Before executing the method of this embodiment, the second device needs to be connected to the third device first.

[0092] In this embodiment, the first device can communicate with the third device through the second device, thereby controlling the third device.

It can be understood that the second device serves as a message transfer station for the first device and the third device.
