[Technical field]

[0001] The present invention relates to the technical field of control methods for intelligent educational appliances, and in particular to a control method for an intelligent full-screen blackboard system integrating recording and broadcasting. [Background technology]

[0002] The most primitive classroom teaching method is that the teacher writes on the blackboard with chalk and then erases the unnecessary writing with a blackboard eraser. The chalk dust left on the blackboard affects the writing effect next time, and it needs to be erased multiple times or even washed with water multiple times; the flying and falling of chalk dust not only pollutes the indoor environment, but is also a source of pollution to the human body. In addition, the teaching content cannot be stored, and the teaching scene at that time cannot be reproduced. Others cannot evaluate the teaching effect based on students' feedback.

[0003] With the improvement of science and technology, improved blackboards have emerged. The podium is equipped with an intelligent host, which is a multifunctional blackboard through projection or setting the display screen in the center of the blackboard. Teachers can still teach in the most original way, and at the same time use the function of the intelligent host to display edited files or audio and video files. This improved blackboard still has the shortcomings of the original blackboard. [Summary of the invention]

[0036] In order to make the technical solution and technical effects of this patent clearer, the specific implementation method of this patent is described in detail below in conjunction with the accompanying drawings and examples.

[0037] First, the recording and broadcasting integrated intelligent full-screen blackboard system in this embodiment includes an audio acquisition module 1, at least one video acquisition module 2, an all-in-one machine 3 and at least one black screen 4; black screens 4 are set on both sides of the all-in-one machine display; the all-in-one machine display can be divided into multiple display areas whose number is not less than the number of black screens and there is a separate display area on the all-in-one machine display corresponding to each black screen; the black screen 4, the audio acquisition module 1, and the video acquisition module 2 are all electrically connected to the all-in-one machine 3.

[0038] like Figure 1 Specifically, the audio acquisition module 1 is used to collect the user's audio signal and output the audio signal to the all-in-one machine 3. It can be electrically connected or wirelessly connected to the all-in-one machine 3. The audio acquisition module 1 in this embodiment is implemented by a microphone.

[0039] There are two video acquisition modules 2, which are arranged at the top of the left and right sides of the smart blackboard and are electrically connected to the all-in-one machine. The video module can rotate to record the image signals of students and / or teachers. A video acquisition module electrically connected to the all-in-one machine 3 can also be arranged at the back of the classroom to record the teaching scene from the rear end of the classroom. The video acquisition module 2 in this embodiment is implemented by a camera.

[0040] The black screen 4 includes a writing touch area 41 and a physical button area 42; the writing touch area 41 may be an infrared touch screen, an electromagnetic touch screen, or a capacitive touch screen, etc., including a writing area 411 and a virtual button area 412. The shape of the writing area 411 matches the black screen 4 and covers the black screen to the maximum extent. The physical button area 42 is located below the writing touch area and is provided with a series of physical buttons, such as save, share, generate QR code, partial erase, one-key screen clear, black screen, resource query, red pen, black pen, blue pen, music, screenshot, mode switching, etc., to enrich the functions of the blackboard and enrich teaching resources. Users can use hard objects, such as chalk and pen shells, to write and draw pictures and texts in the writing area. The virtual key area 412 is a series of touch marks with similar functions to physical keys, and is arranged at the edge of the black screen writing touch area 41. In this embodiment, the virtual key area 412 of the left black screen is arranged at the left edge of the writing touch area 41, and the virtual key area 412 of the right black screen is arranged at the right edge of the writing touch area 41. The silk-screen marks indicate different function shortcut keys. The virtual shortcut keys can respond quickly to user operations, which is convenient and fast, and improves processing efficiency.

[0041] There are two black screens 4, which are respectively arranged on the left and right sides of the all-in-one machine 3. The all-in-one machine display includes a left display area 31 and a right display area 32. The left display area 31 corresponds to the left black screen, and the right display area 32 corresponds to the right black screen. The two black screens 4 and the all-in-one machine 3 are arranged side by side to form an intelligent blackboard that matches the shape of the physical blackboard in the current classroom. The black screen 4 is used to display the writing blackboard of the teacher or the student. The all-in-one machine display is used to display the black screen writing blackboard in the same screen mode or to display its own writing blackboard in the split screen mode, and to display the image signal collected by the video acquisition module 2 at the same time; the black screen 4 is a black LCD screen, and the all-in-one machine display is a white LCD screen. The black black screen takes into account the writing habits of some users on the original blackboard, which is equivalent to a white computer LCD screen, and has low power consumption and is environmentally friendly. There are other changes in the correspondence between the all-in-one machine display and the black screen. For example, the all-in-one machine display is divided into three or more display areas, two of which correspond to the left and right black screens one by one, and the other display areas can be used for separate writing in the same screen mode or the display of the image signal collected by the video acquisition module 3, or the corresponding Braille interpretation screen, etc.

[0042] The mechanical connection between the black screen 4 and the integrated machine 3 is a buckle fixation, which is convenient for the disassembly and assembly of the intelligent blackboard system. The electrical connection between the black screen 4 and the integrated machine 3 is a USB connection, which improves the standardization of the equipment.

[0043] The all-in-one display is also provided with icons or shortcut keys with functions similar to the virtual keys on the black screen, so that the user can edit the blackboard writing on one side of the all-in-one 3 conveniently.

[0044] The recording and broadcasting integrated intelligent full-screen blackboard system in this embodiment also includes physical peripheral devices connected to the all-in-one machine, such as a wired / wireless keyboard, a mouse, etc.

[0045] like Figure 2 The black screen includes a black screen acquisition unit, a black screen display unit, a black screen communication unit and a black screen control unit.

[0046] A black screen acquisition unit, used to collect writing track information, physical key information and virtual key information on the black screen in real time and form a data packet;

[0047] A black screen display unit, used to display written information in real time according to the instruction of the black screen control unit;

[0048] A black screen communication unit, used to send data from the black screen control unit to the following all-in-one communication unit, and receive data from the all-in-one communication unit;

[0049] A black screen control unit, used for parsing the data packets of the black screen acquisition unit and sending the parsed data to the black screen display unit;

[0050] The all-in-one machine comprises an all-in-one machine acquisition unit, an image acquisition unit, an audio acquisition unit, an all-in-one machine display unit, an all-in-one machine storage unit, an all-in-one machine communication unit and an all-in-one machine control unit.

[0051] The integrated machine acquisition unit is used to collect the writing track information on the integrated machine display, the physical peripheral input information connected to the integrated machine and the virtual key input information on the integrated machine display in real time and form a data packet;

[0052] An image acquisition unit is used to acquire image signals in the classroom in real time and output them to the all-in-one control unit, including images of students and teachers;

[0053] The audio acquisition unit is used to collect the user's audio signal in real time and output it to the all-in-one control unit;

[0054] The all-in-one display unit is used to display the written information and image information in real time according to the instructions of the all-in-one control unit;

[0055] The all-in-one storage unit is used to store the screen of the all-in-one display and the real-time audio signal in real time according to the instructions of the all-in-one control unit to generate a video file; the video file format is such as avi, MP4, swf.

[0056] The integrated machine communication unit is used to send data from the integrated machine control unit to the black screen communication unit and receive data from the black screen communication unit;

[0057] The all-in-one control unit is used to parse the data packets from the all-in-one acquisition unit and / or the all-in-one communication unit and send the parsed data to the all-in-one display unit, process the data from the image acquisition unit and send the processed data to the all-in-one display unit, and process the data from the audio acquisition unit and send it to the all-in-one storage unit.

[0058] The recording and broadcasting integrated intelligent full-screen blackboard system in this embodiment can work in two modes: same-screen mode and split-screen mode. In same-screen mode, the all-in-one display synchronously displays the writing information on the black screen; in split-screen mode, the all-in-one display and the black screen separately display their own writing information and respond to their own physical key input and virtual key input.

[0059] Same screen mode

[0060] The control method of the recording and broadcasting integrated intelligent full-screen blackboard system in this embodiment is divided into three cases: writing display control, physical key input control and virtual key input control.

[0061] like Figure 3 , the control method of the intelligent blackboard system during writing display includes the following steps:

[0062] a10: The black screen collects writing track information in real time and forms a data packet in a custom format;

[0063] b10: black screen parses the data packet in step a10;

[0064] c10: Black screen shows the writing track according to the parsed data;

[0065] Black screen Perform the following steps while executing step b10:

[0066] b11: The black screen sends the data packet in step a10 to the all-in-one machine through the USB protocol;

[0067] The intelligent blackboard system control method also includes the following steps when writing and displaying:

[0068] a11: The camera collects image information in real time;

[0069] a12: Microphone collects audio information in real time;

[0070] c11: The all-in-one machine receives the data packet from the black screen through the USB protocol and parses it into information of points corresponding to the position of the all-in-one machine display;

[0071] d10: The all-in-one machine draws the corresponding writing track on the display according to the analysis information, and displays the image information at the same time; in order to avoid the image information blocking the writing track, the image information can be displayed in the form of a small window at the upper left and upper right, or the lower left and lower right, or other positions of the all-in-one machine display.

[0072] e10: The all-in-one machine stores the display image and audio signals in real time and generates video files.

[0073] like Figure 4 The control method of the recording and broadcasting integrated intelligent full-screen blackboard system includes similar steps when physical key input is used and the steps when writing and displaying are used. The difference is that the signal collected in real time by the black screen is converted into physical key information. Subsequently, the black screen and the all-in-one machine parse the physical key information into corresponding functional modules, and then perform corresponding functional processing on the writing information before the physical key input.

[0074] like Figure 5 The control method of the recording and broadcasting integrated intelligent full-screen blackboard system includes the following steps when the virtual key input is performed:

[0075] a20: The black screen collects virtual key information in real time and forms a data packet in a custom format;

[0076] a21: The camera collects image information in real time;

[0077] a22: Microphone collects audio information in real time;

[0078] b20: The black screen sends the data packet in step a20 to the all-in-one machine through the USB protocol;

[0079] c20: The all-in-one machine receives the data packet from the black screen through the USB protocol and parses it into the corresponding functional modules;

[0080] d20: the all-in-one machine response function module displays the updated writing information on the display and displays the image information at the same time;

[0081] e20: The all-in-one machine stores the display image and audio signals in real time and generates video files.

[0082] After step c20, the following steps are also included:

[0083] d21: The integrated machine sends the data packet corresponding to the functional module in step c20 to the black screen through the USB protocol;

[0084] e21: black screen parsing the data packet in step d21;

[0085] f21: The black screen response function module displays the updated writing information.

[0086] After the black screen virtual key is input, the black screen sends the data packet to the all-in-one machine for parsing and processing through the USB protocol. At the same time, the black screen updates the written information according to the instructions of the all-in-one machine. The black screen and the all-in-one machine display are displayed on the same screen, ensuring the accuracy of the data stored in the all-in-one machine and avoiding data loss caused by the rapid response of the virtual key.

[0087] Split Screen Mode

[0088] Figure 6 This is a flow chart of the control method of the black screen and the all-in-one machine in the split-screen mode. The control method is similar to the same-screen mode. The difference is that the black screen and the all-in-one machine collect their own input information, and process and display the input information. There is no data interaction between the black screen and the all-in-one machine, and the specific steps will not be repeated here.

[0089] The above control method is easy to understand. The collection and analysis of the black screen and the user's writing information of the all-in-one machine can also be regarded as a writing function module. The virtual button can also be understood as a virtual menu, etc.

[0090] When the user has a playback demand, the video file with writing, image and audio stored on the all-in-one machine can be played, or the video file can be copied and shared. The video file recorded by the intelligent blackboard system in this embodiment can also be read by the all-in-one machine, and the physical peripherals and virtual function modules of the all-in-one machine can be used to perform secondary editing on the writing information to meet the user's correction or update needs, while the existing directly recorded teaching image files, the writing information and the surrounding environment image information are an inseparable video signal, and the writing information cannot be edited and modified; so compared with the teaching image files in the existing mode, the teaching files generated by this intelligent blackboard system have a higher utilization rate, which reduces the workload of teachers. At the same time, the video file contains the image information and audio information of teachers and students, which is also convenient for evaluating the teaching quality of teachers, and can also be further improved according to the on-site feedback of students.

[0091] The above description is only the preferred embodiment of this patent and is not intended to limit this patent. For those skilled in the art, this patent may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this patent shall be included in the protection scope of this patent.
