Large file calling management method and system

Abstract

The invention discloses a large file calling management method and system. According to the method, the file needing to be used is transmitted to the terminal in advance, and the unique ID is allocated to the used file, so that the ID corresponds to the file. When a large file needs to be called, a single file does not need to be transmitted, only the ID needs to be transmitted, and then the reading and calling steps are directly completed by the terminal, so that the situation that the large file needs to be transmitted through Bluetooth or WIFI in each time of use is avoided, and the existing problems of slow transmission and easy interruption are solved.

Description

Technical Field

[0001] The present invention relates to the field of information transmission management, and more specifically, to a large file call management method and system. Background Art

[0002] For a terminal that needs to play streaming media, the media material to be played needs to be transmitted to the terminal, and then the terminal plays it. In the existing file transfer technology, wireless protocols such as Bluetooth and WIFI are generally used for transmission. The above wireless transmission methods have the advantages of good adaptability and wide application. However, when large files need to be transmitted, there are speed limitations when using wireless protocols such as Bluetooth and WIFI, which leads to slow transmission speed and is prone to transmission interruption or high delay.

[0003] Taking LED display screens as an example, if existing display screens need to display videos, they need to perform external streaming or transmit the displayed videos to the LED display screen storage medium. However, for high-definition videos, the transmission process is long and prone to interruptions. Summary of the invention

[0004] The present invention overcomes the deficiencies of the prior art and provides a large file call management method and system, in the hope of solving the problems of slow large file transmission and easy interruption in the prior art.

[0005] In order to solve the above technical problems, one aspect of the present invention provides a large file call management method;

[0006] A large file call management method comprises the following steps:

[0007] Transfer large files to the terminal, and the terminal stores the large files;

[0008] Assign unique IDs to stored large files;

[0009] The control end transmits the ID of the large file to be called to the terminal;

[0010] The terminal calls the large file corresponding to the large file ID transmitted by the control end.

[0011] By transferring the required files to the terminal in advance and assigning a unique ID to the files to be used, the unique ID can be directly transmitted when a large file is needed, thus avoiding the need to transfer large files using Bluetooth or WIFI every time they are used, solving the existing problems of slow transmission and easy interruption.

[0012] A further technical solution is that the transmission of the large file to the terminal specifically includes the following steps:

[0013] The control end transmits directly to the terminal;

[0014] Alternatively, the large file is transferred to the web page background, and the web page background transfers the large file to the terminal;

[0015] Alternatively, burn large files directly to the terminal storage media.

[0016] A further technical solution is that the allocation of IDs to the stored large files includes the following steps:

[0017] Transfer large files to the server;

[0018] The server stores large files and assigns unique IDs to them;

[0019] The server transmits the large file and its corresponding allocation ID information to the terminal.

[0020] Transferring large files to the server and having the server save them synchronously and assigning IDs can form file backups on the server. In addition, the server storage files can be managed in a variety of ways later, and the server can communicate with the terminal to update and manage large files and ID information.

[0021] A further technical solution is to perform the following steps after transferring the large file to the server:

[0022] The server compares the received large file with the large file already stored in the terminal;

[0023] If the files are inconsistent, execute the subsequent steps;

[0024] If the files are consistent, the server sends a prompt message to the control terminal;

[0025] The control end chooses to continue the storage or stop the storage, and sends the instruction to the server and the terminal.

[0026] Comparing uploaded files with stored files can avoid wasting storage space by storing the same files repeatedly.

[0027] A further technical solution is that the control end performs the following steps before transmitting the ID of the large file to be called to the terminal;

[0028] The control end requests the server or terminal to store the large file information;

[0029] The server or terminal transmits the stored large file information to the control terminal.

[0030] A further technical solution is that the large file information shown includes one, any combination or all of the large file upload time, uploading user, file name, file size, and file preview content.

[0031] For users, the correspondence between the ID assigned by the server or terminal and the file is not obvious. To facilitate user use, users can request the server or terminal to store large file information through the control terminal, and obtain large file information such as upload time, upload user, file name, file size, file preview content, etc. for identification, which is convenient for customers to identify.

[0032] A further technical solution is that the large file is transmitted to the terminal, and the terminal stores the large file, including the following steps:

[0033] Classify large files into categories of changeable files and unchangeable files, and transmit the file category information and the files to the terminal;

[0034] The editable large files are stored in the editable partition of the terminal, and the uneditable large files are stored in the uneditable partition of the terminal.

[0035] The present invention also provides a large file call management system, comprising: a terminal, a control terminal;

[0036] The terminal is used to store large files, receive the large file ID transmitted by the control terminal, and call the corresponding large file according to the ID;

[0037] The control end is used to transmit the ID of the large file to be called to the terminal.

[0038] A further technical solution is that the large file call management system also includes a web page background and a server;

[0039] The web page backend is used to receive large files and transmit the large files to the terminal and the server;

[0040] The server is used for comparing the received large file with the large file already stored in the terminal; storing the large file and assigning a unique ID to the large file; and transmitting the large file assigned ID information to the terminal.

[0041] Compared with the prior art, the present invention has at least the following beneficial effects: the present invention realizes the correspondence between the ID and the file by transmitting the required file to the terminal in advance and assigning a unique ID to the file to be used. When a large file needs to be called, there is no need to transmit the single file itself, but only the ID, and then the terminal directly completes the reading and calling steps, thereby avoiding the need to use Bluetooth or WIFI to transmit large files every time they are used, and solving the existing problems of slow transmission and easy interruption. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Figure 1 The present invention is a flowchart of an implementation method of a large file call management method. DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] Embodiment 1

[0045] A large file call management method, see Figure 1 , including the following steps:

[0046] S1: transfer the large file to the terminal, and the terminal stores the large file;

[0047] It should be noted that the terminal may be a device that needs to call media materials, such as a smart speaker and an LED display device. In the present embodiment, the terminal is an LED display device, and the large file is a media file with a relatively large volume.

[0048] Large files can be transferred to the terminal directly from the control end, or transferred to the web page background, which will transfer the large files to the terminal; large files can also be burned directly to the terminal storage medium.

[0049] In this embodiment, the large file is transmitted to the terminal by transmitting the large file to the web page background, and the web page background transmits the large file to the terminal;

[0050] It should be noted that, in this embodiment, large files are divided into categories of modifiable files and unmodifiable files, and the file category information and the files are transmitted to the terminal together;

[0051] The editable large files are transmitted to the webpage background and stored in the editable partition of the terminal, and the uneditable large files are directly burned and stored in the uneditable partition of the terminal. The editable partition and the uneditable partition are logical partitions.

[0052] The editable partition where the large files are stored can be modified by any account, including adding, deleting, and modifying other file information;

[0053] In the unchangeable partition, only the administrator account can make changes. The administrator account can log in through the server or the control terminal, and the changes are sent to the terminal through the control terminal.

[0054] In this embodiment, the control end is a terminal with an application installed.

[0055] S2: Assign unique IDs to stored large files;

[0056] It should be noted that, in this embodiment, the step of allocating an ID to a stored large file includes the following steps:

[0057] S21: transferring large files to the server;

[0058] The large file can be transmitted from the web page background to the server, or from the control terminal to the server. In this embodiment, the large file is transmitted from the web page background to the server; since the server may correspond to multiple terminals;

[0059] S22: In order to ensure that files in multiple terminals are all assigned unique IDs, the server performs an operation of assigning unique IDs.

[0060] In this embodiment, the large file is a video file, the storage partition is a modifiable partition, and the unique ID assigned by the server is "0x80EA0092";

[0061] S23: The server transmits the large file and its corresponding allocation ID information to the terminal.

[0062] It should be noted that the video file can be modified through the server or the control terminal. When the video file needs to be modified, it is assumed that the beginning animation of the video is a text: "ABCD";

[0063] The first modification is to change the beginning text of the video stored on the server to "1234", and the ID remains unchanged;

[0064] The second modification is to change the beginning text of the video stored on the server to "5678", and the ID remains unchanged;

[0065] When the terminal is first assigned an ID, it stores the video and ID "0x80EA0092". No matter when the control terminal connects to the terminal later, since the video ID remains unchanged and unique, the video stored in the terminal can be directly changed to the latest version through the server or the control terminal, that is, "ABCD" can be directly changed to "5678", and the ID will not change;

[0066] Whether to transfer the latest version of the video file that has been modified on the server to the terminal to update the terminal video is controlled by the operator;

[0067] Furthermore, the operator can modify and update the videos stored on multiple terminals that are consistent with the server ID through the videos stored on the server;

[0068] S3: The control end requests the server or terminal to store the large file information; the server or terminal transmits the stored large file information to the control end.

[0069] It should be noted that, in this embodiment, the large file is a playable media file, and the large file information includes the upload time, uploading user, file name, file size, and media preview content of the media file. For video files, the preview file can be a video screenshot or a dynamic preview video.

[0070] S4: The control end transmits the ID of the large file to be called to the terminal;

[0071] S5: The terminal calls the large file corresponding to the large file ID transmitted by the control end.

[0072] Specifically in this embodiment, when the LED device receives the corresponding ID of the large file from the control end, the control system of the LED device will search for the corresponding large file in the built-in storage according to the ID, and the file management system of the LED device will quickly locate the storage location of the material and read it into the memory. The LED device will then present the material through the corresponding display hardware. In this process, the LED device no longer needs to rely on the network for file transfer, and all the materials are already built-in and stored locally on the device. It only needs to be quickly called through the ID.
