Therefore, the method for displaying the image data solves the technical problem that the data with higher security level in the related technology cannot be put in a display screen because the data is not allowed to be uploaded to a large-screen server.
In an alternative embodiment, the method for acquiring the connection address corresponding to the identification code obtained through the identification code identification operation and loading the data acquisition module with the image data acquisition function based on the connection address comprises the following steps: scanning the identification code in the display device by using a second processing module of the terminal device; triggering a predetermined application based on the operation of scanning the identification code; accessing the data acquisition module through a preset application, and loading the data acquisition module to the terminal equipment.

It should be noted that, in the embodiment of the present invention, the terminal device and the processing server may be disposed in the same local area network.
In addition, in the embodiment of the present invention, the identification code may be a two-dimensional code, and the two-dimensional code may be connected with a program (i.e., the predetermined application) that triggers the loading data acquisition module; when the terminal equipment accesses the program through the two-dimension code, the program can be triggered to load the data acquisition module to the terminal equipment.
In addition, the data acquisition module may be a soft S, i.e., a soft acquisition end.
The soft S program comprises address information of a temporary storage module for storing the acquired image data.
Under an application scene, the two-dimensional code on the display device can be scanned through the second processing module of the terminal device, and soft S is loaded from the connection address of the two-dimensional code.
In an alternative embodiment, the control data acquisition module sends the acquired image data to a temporary storage module in the processing server, comprising: determining that the data acquisition module is successfully loaded through the second processing module; determining that a trigger operation acting on the terminal equipment is received; determining the type of triggering operation as a release instruction; and sending a data acquisition instruction to the data acquisition module through the second processing module so as to acquire the image data of the desktop of the terminal equipment by using the data acquisition module, wherein the data acquisition module sends the image data to the wireless connection module of the processing server after acquiring the image data of the desktop of the terminal equipment, and the wireless connection module sends the image data to the temporary storage module.
That is, after the second processing module in the terminal device determines that loading of the data acquisition module is completed, whether a control instruction is received or not can be judged, if the control instruction for starting delivery is received, that is, when the control instruction is delivered, the data acquisition instruction is sent to the data acquisition module through the second processing module of the terminal device, after the data acquisition instruction is received, the data acquisition module acquires image data of a desktop of the terminal device, and sends the acquired image data of the desktop to the wireless connection module of the processing server after encoding.
In this embodiment, when the second processing module of the terminal device scans the two-dimensional code on the large-screen device, the soft S is loaded from the connection address of the two-dimensional code, and at the same time, the control column is acquired.
The second processing module of the terminal device loads the soft S and the control bar displayed on the desktop of the terminal device from the connection address of the two-dimensional code by scanning the two-dimensional code displayed on the display device. At this time, the user can see the control bar on the screen of the terminal device.
Wherein, include in the control column: a start release key and a stop release key; the start release key is used for releasing the picture of the desktop of the terminal equipment into the large screen equipment, and the stop release key is used for stopping releasing the picture of the desktop of the terminal equipment into the display equipment.
Fig. 3 is a schematic diagram of a control bar according to an embodiment of the present invention, in which a large frame 31 in fig. 3 is a terminal device, an inner frame 32 is a screen of the terminal device, and black small frames 33 on the screen are control bars, respectively, a start release key and a stop release key. Of course, the control bar may be dragged by the user to any location in the screen.
It should be further noted that, in the embodiment of the present invention, after the soft S is loaded, a control bar is displayed on the desktop of the terminal device, or when the soft S is being loaded, the control bar is gray, and the click is invalid; after the soft S is loaded, the control bar restores to normal color, and the corresponding function can be realized after clicking.

For example, after the user triggers a start-to-put key in the control bar and the second processing module receives a control instruction to start putting, a data acquisition instruction is sent to the soft S, and meanwhile, the control bar displayed on the screen is hidden; after receiving the data acquisition instruction, the soft S acquires the image data of the desktop of the terminal equipment, encodes the image data of the desktop, and sends the encoded image data of the desktop to a temporary storage module in the processing server.
It should be noted that, the data to be released is displayed on the desktop of the terminal device, and when the desktop image data is collected, the control bar is hidden, so that the collected desktop image is the data to be released.
In addition, it should be noted that, when the temporary storage module receives the encoded image data, the encoded desktop image data is sent to the first processing module, and the encoded image data is deleted.
In this embodiment, the temporary storage module may send the image data after receiving the frame code to the first processing module after each time the frame code is received; then, the desktop image data encoded by the frame is deleted.
Of course, the image data after being encoded may be received by a predetermined frame number and then sent to the first processing module. May be set according to the actual situation.
In an alternative embodiment, after receiving the image data, the first processing module divides the image data based on layout information of a plurality of sub-display screens in the display device to obtain a plurality of sub-image data, and encodes the plurality of sub-image data to obtain encoded plurality of sub-image data.
In another alternative embodiment, the first processing module is further configured to send the encoded plurality of sub-image data to each of the plurality of receiving terminals based on the layout information, so as to decode the received sub-target encoded data by using each of the plurality of receiving terminals, and send the decoded sub-image data to the sub-display screen connected to each receiving terminal, so as to display the sub-target data sent by each receiving terminal by using the sub-display screen connected to each receiving terminal.
In the embodiment of the invention, the display device comprises a plurality of sub-display screens, the image data is divided to obtain a plurality of sub-target image data, and the layout information of the plurality of sub-display screens in the display device can be obtained, wherein the layout information comprises: the arrangement mode of the plurality of sub-display screens in the display screen is determined based on the identification information of each sub-display screen in the plurality of sub-display screens determined by the arrangement mode; and dividing the target image data based on the layout information to obtain a plurality of sub-target image data.
In this embodiment, the processing module of the processing server may divide the image data according to layout information of a plurality of sub-display screens of the display device in the display device, to obtain a plurality of sub-image data.
In this step, the first processing module of the processing server decodes the encoded data after receiving the encoded data, resulting in image data of the terminal device. Since the display device includes a plurality of sub-displays, the desktop image data needs to be divided according to a preset layout of the plurality of sub-displays of the display device.
The layout information refers to the arrangement mode of the plurality of sub-display screens in the display device and the identification of the display device corresponding to each position of the display device.
For example, the display device includes four sub-displays, which may then form a large screen device (i.e., a display device in context) in a "field" font layout; the identifiers of the sub display screens which are sequentially arranged from left to right and from top to bottom are respectively '001', '002', '003' and '004'; for another example, the display device includes nine word display screens, and then the nine sub display screens may form a large screen device in a "nine-grid" layout manner; the identifiers of the sub display screens arranged in sequence from left to right and from top to bottom are '010', '011', '012', '013', '014', '015', '016', '017', '018', respectively.
When the large screen device consists of four sub display screens in a field-shaped display mode, the image data can be uniformly divided into four small images; when the large screen device is composed of nine sub-display screens in a display manner of "nine squares", the image data can be equally divided into nine small drawings.
In addition, after dividing the target image data based on the layout information to obtain a plurality of sub-target image data, each of the plurality of sub-image data may be encoded to obtain a plurality of sub-encoded data.
That is, after dividing into a plurality of sub-image data, each sub-image data needs to be encoded to obtain a plurality of sub-encoded data.
In an alternative embodiment, the sending of the target image data to the display screen for displaying the target image data with the display screen may be achieved by: transmitting the plurality of sub-coded data to a plurality of receiving terminals based on the layout information, wherein the plurality of receiving terminals are connected with a plurality of sub-display screens; controlling each of the plurality of receiving ends to decode the received sub-encoded data; and transmitting the decoded sub-image data to the sub-display screen connected with each receiving end by using each receiving end so as to display the sub-image data transmitted by each receiving end by using the sub-display screen connected with each receiving end.
In this embodiment, the processing module of the processing server may determine, according to a layout of a plurality of sub-display screens of a preset display device, a sub-display screen corresponding to each sub-target encoded data, and send each sub-target encoded data to a receiving end connected to the determined sub-display screen in the receiving module of the processing server.
For example, the layout of a plurality of sub-display screens of the preset large-screen device is as follows: the four sub-display screens form large-screen equipment in a 'field' -shaped layout mode, the identifiers of the sub-display screens which are sequentially arranged from left to right and from top to bottom are respectively '001', '002', '003' and '004', and then the desktop image is divided into four small images of an upper left small image, a lower left small image, an upper right small image and a lower right small image; the processing module of the processing server sends the small image coding data (i.e., sub-target coding data) of the small image at the upper left corner to the receiving end of the sub-display screen connection marked 001, sends the small image coding data of the small image at the upper right corner to the receiving end of the sub-display screen connection marked 002, sends the small image coding data of the small image at the lower left corner to the receiving end of the sub-display screen connection marked 003, and sends the small image coding data of the small image at the lower right corner to the receiving end of the sub-display screen connection marked 004.
And after receiving the sub-coded data, each receiving terminal restores the sub-image data and sends the sub-image data to a sub-display screen connected with each receiving terminal, wherein the sub-display screen displays the sub-image data.
In this step, each receiving end may decode the received sub-encoded data to obtain sub-image data, and send the sub-image data to the connected sub-display screen, where the sub-display screen displays the sub-image data, so that a plurality of sub-image data form a complete image data, that is, desktop image data displayed on the desktop of the terminal device.
In an alternative embodiment, the method for displaying image data may further include: determining the type of triggering operation as a stopping instruction; and sending a data acquisition stopping instruction to the data acquisition module through the second processing module, wherein the data acquisition module stops image data acquisition operation after receiving the data acquisition stopping instruction.
In this embodiment, if a control instruction to stop delivery is received, a stop acquisition instruction is sent through a second processing module of the terminal device, and after the data acquisition module receives the stop acquisition instruction, image data of the terminal device is stopped being acquired.
In this embodiment, when the user triggers the stop release key in the control field, the second processing module sends a stop acquisition instruction to the soft S after receiving the control instruction to stop release; and after receiving the acquisition stopping instruction, the soft S stops acquiring desktop image data.
Fig. 4 is a schematic diagram of an image data display system according to an embodiment of the present invention, as shown in fig. 4, may include: the large screen device (i.e. display device) is provided with a two-dimensional code; the processing server is connected with the large-screen equipment and comprises: a processing module 2 (i.e., a first processing module), a receiving module R, a wireless connection module, and a temporary storage module; and the terminal equipment is connected with the processing server, wherein the terminal equipment can comprise a processing module 1 (namely a second processing module) and is soft S. The large screen device is composed of a plurality of display screens. The receiving module R in the processing server comprises a plurality of R ends, and a display screen is connected with one R end. The large screen device and the processing server are arranged together and connected through a wire.
Through the image data display system, the terminal equipment which stores the data to be put in can scan the two-dimensional code displayed by the large-screen equipment, trigger the loading of the soft S on the terminal equipment, and acquire the desktop image of the terminal equipment (the data to be put in is displayed on the desktop); next, the soft S sends the collected desktop image data to a temporary storage module in the processing server for storage; then, a processing module in the processing server acquires desktop image data from the temporary storage module, divides the desktop image data to obtain a plurality of small images, sends the small images to each R end connected with each display screen, and displays the small images in each display screen of the large-screen device by each R end. Wherein, the temporary storage module can delete the desktop image data after the processing module reads.
Therefore, the data to be put in can be put in the large-screen equipment only by temporarily storing the data in the temporary storage module without uploading the data to the large-screen server, and the temporary storage module can automatically delete the stored data, so that the safety is higher.
