[0005] Functional limitations: Existing electronic classroom mirror management systems are relatively simple in function and cannot support diverse teaching scenarios and needs, thus limiting teachers' ability to use advanced technologies and innovative teaching methods in their teaching. Summary of the Invention

[0006] The purpose of this invention is to provide a method and system for managing electronic classroom images under a domestically developed information technology (IT) environment. By using full and incremental electronic classroom images designed entirely for this environment, and by modifying the startup logic of the IT operating system, it is possible to achieve automated deployment of interactive teaching and unified management of different terminals in multiple computer classrooms, thereby improving operational efficiency. This invention is achieved through the following technical solutions.

[0007] In a first aspect, the present invention provides a method for mirror management of electronic classrooms under a domestically developed information technology environment, comprising: The teacher-side controller uses a base image to obtain a full image of the electronic classroom and uploads it to the resource server; the base image is the original domestically developed operating system. The incremental electronic classroom image is obtained based on the full electronic classroom image and uploaded to the resource server using the teacher-side controller. The teacher-side controller sends control commands to the resource server, which then distributes the full and incremental electronic classroom images to the student terminals based on the received control commands. The student-end controller is used to download and start the full and incremental electronic classroom images obtained by the student end. The starting process includes: modifying the script based on the original domestically developed operating system to change the read-only mode mount of the boot partition of the original domestically developed operating system to read-write mode mount; combining the domestically developed operating system files in the full and incremental electronic classroom images to obtain the root directory in which the domestically developed operating system can run; clearing the cached data in the root directory; and starting the root directory.

[0009] Optionally, the custom file transfer protocol is a modified version of the P2P communication protocol BitTorrent protocol, with a custom header GeitFileShareServer.

[0010] Optionally, using the teacher-side controller to obtain an incremental electronic classroom image based on the full electronic classroom image and upload it to the resource server includes: using the teacher-side controller to update the domestically developed operating system file in the full electronic classroom image to obtain the updated domestically developed operating system file, using the updated domestically developed operating system file as the incremental electronic classroom image, establishing a signaling connection with the WEB terminal, submitting an incremental electronic classroom image creation application, and after successful creation authorization, establishing a connection with the resource server, and uploading the incremental electronic classroom image to the resource server single-point through a custom file transfer protocol; wherein, the custom file transfer protocol is a custom message header based on the P2P communication protocol.

This includes: constructing a mirror source list through a custom file transfer protocol, and distributing the full and incremental electronic classroom images in the mirror source list to all student terminals; wherein, the mirror source list includes multiple full electronic classroom images and an incremental electronic classroom image corresponding to each full electronic classroom image.

[0012] Optionally, downloading the full and incremental electronic classroom images obtained by the student terminal using the student terminal controller includes: starting any one of the student terminals, establishing a signaling connection with the resource server, and reporting the available image resources and resource access ports of the student terminal; wherein, the available image resources include the full and incremental electronic classroom images obtained by the student terminal.

[0013] Optionally, if the resource access port is accessible, a custom file transfer protocol sharing environment can be built in the electronic classroom to allow other students to download the domestically developed operating system files from the full and incremental electronic classroom images. If the resource access port is inaccessible, a multi-threaded task can be created to download the domestically developed operating system files from the full and incremental electronic classroom images in segments.

[0014] Secondly, the present invention provides an electronic classroom mirror management system under the information technology innovation environment, including: a teacher-side controller, a resource server, and a student-side controller; The teacher-side controller is configured to perform the following steps: The full set of electronic classroom images is obtained based on the base image and uploaded to the resource server; the base image is the original domestically developed operating system. Incremental electronic classroom images are obtained based on full electronic classroom images and uploaded to the resource server; Send control commands to the resource server, so that the resource server will distribute the full electronic classroom image and the incremental electronic classroom image to the student terminals according to the received control commands; The student-side controller is configured to perform the following steps: The process of downloading and launching the full and incremental electronic classroom images obtained from the student end includes: modifying the script based on the original domestically developed operating system to change the read-only mount mode of the original domestically developed operating system's boot partition to read-write mount mode; combining the domestically developed operating system files in the full and incremental electronic classroom images to obtain the root directory in which the domestically developed operating system can run; clearing the cached data in the root directory; and launching the root directory.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention introduces a method for managing electronic classroom images under a domestically developed information technology (IT) environment. By using full and incremental electronic classroom images designed entirely for this environment, it ensures seamless compatibility between the images and the IT hardware and software platforms, enabling seamless replacement and efficient operation. The IT operating system employs advanced security mechanisms to ensure data security and system stability, meeting the stringent information security requirements of IT reform. The IT operating system provides flexible image management, deployment, and maintenance functions, supporting rapid deployment and efficient management of large-scale electronic classrooms, thereby reducing the workload of school IT management. After distributing the image to all student terminals, other students can choose to download the IT operating system files from accessible resource access ports or from the resource server. This allows schools to better adapt to the requirements of IT reform, improve electronic classroom management efficiency and teaching effectiveness, and provide strong support for the development of educational informatization. Furthermore, because this invention uses a custom file transfer protocol, network firewall rules will not block it, thus enabling rapid image file distribution even when internet P2P services are disabled in the computer room.

In this description, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0018] Example 1 This embodiment introduces a method for mirror management of electronic classrooms in a domestically developed information technology environment, such as... Figure 1 As shown, it includes: The teacher-side controller uses a base image to obtain a full image of the electronic classroom and uploads it to the resource server; the base image is the original domestically developed operating system. The incremental electronic classroom image is obtained based on the full electronic classroom image and uploaded to the resource server using the teacher-side controller. The teacher-side controller sends control commands to the resource server, which then distributes the full and incremental electronic classroom images to the student terminals based on the received control commands. The student-end controller is used to download and start the full and incremental electronic classroom images obtained by the student end. The starting process includes: modifying the script based on the original domestically developed operating system to change the read-only mode mount of the boot partition of the original domestically developed operating system to read-write mode mount; combining the domestically developed operating system files in the full and incremental electronic classroom images to obtain the root directory in which the domestically developed operating system can run; clearing the cached data in the root directory; and starting the root directory.

[0019] Example 2 Based on Example 1, this example introduces the specific implementation process of an electronic classroom mirror management method in a domestically developed information technology environment, which includes the following: In one specific embodiment of the present invention, the process of obtaining a full electronic classroom image based on a base image using a teacher-side controller and uploading it to a resource server includes: using the teacher-side controller to install educational software based on the original domestic IT innovation operating system to obtain a full electronic classroom image, establishing a signaling connection with the WEB terminal, submitting a full electronic classroom image creation application, and after successful creation authorization, establishing a connection with the resource server and uploading the full electronic classroom image to the resource server single-point through a custom file transfer protocol.

[0020] In one specific embodiment of the present invention, the custom file transfer protocol is modified from the P2P communication protocol BitTorrent protocol to a custom message header GeitFileShareServer.

[0021] Custom file transfer protocols such as Figure 6 As shown, Figure 6 The document demonstrates the transmission process of P2P messages. In an intranet environment, due to bandwidth limitations, schools typically enable P2P protocol blocking by default. However, in this invention, a custom P2P protocol, with modified message headers, is not blocked by the firewall and is not responded to by standard P2P clients, enabling rapid distribution of image files within the intranet. Image files refer to the domestically developed operating system files within the full and incremental electronic classroom images.

[0022] In one specific embodiment of the present invention, the process of obtaining an incremental electronic classroom image based on the full electronic classroom image using a teacher-side controller and uploading it to a resource server includes: updating the domestically developed operating system file in the full electronic classroom image using the teacher-side controller to obtain the updated domestically developed operating system file; using the updated domestically developed operating system file as the incremental electronic classroom image; establishing a signaling connection with the web terminal; submitting an application for building an incremental electronic classroom image; after successful authorization for building the image, establishing a connection with the resource server; and uploading the incremental electronic classroom image to the resource server single-point through a custom file transfer protocol.

[0023] In one specific embodiment of the present invention, the method of sending control commands to the resource server using the teacher-side controller, so that the resource server distributes the full electronic classroom image and the incremental electronic classroom image to the student terminals according to the received control commands, includes: constructing a mirror source list through a custom file transfer protocol, and distributing the full electronic classroom image and the incremental electronic classroom image in the mirror source list to all student terminals; wherein, the mirror source list includes multiple full electronic classroom images and the incremental electronic classroom image corresponding to each full electronic classroom image.

[0024] In one specific embodiment of the present invention, downloading the full and incremental electronic classroom images obtained by the student terminal using the student terminal controller includes: starting any one of the student terminals, establishing a signaling connection with the resource server, and reporting the available image resources and resource access ports of the student terminal; wherein, the available image resources include the full and incremental electronic classroom images obtained by the student terminal.

[0025] If the resource access port is accessible, a custom file transfer protocol sharing environment is built in the electronic classroom to allow other students to download the domestically developed operating system files from the full and incremental electronic classroom images. If the resource access port is inaccessible, a multi-threaded task is created to download the domestically developed operating system files from the full and incremental electronic classroom images in segments.

[0026] In one specific embodiment of the present invention, the acquisition of both the full electronic classroom image and the incremental electronic classroom image is performed on the template machine.

[0027] like Figure 2 The diagram shown is a schematic of a teacher management webpage in one embodiment of the present invention. In this embodiment, the teacher-side control computer distributes the full and incremental electronic classroom images from the resource server to the student-side. The teacher-side is... Figure 2 The teacher management webpage shown. Figure 2The demonstration showcases some operational functions on the teacher's end. After installing the client software on the template machine, the teacher can extract the full and incremental electronic classroom images. Upon successful extraction, the full and incremental electronic classroom images are sent to the resource server. After obtaining the full electronic classroom image, the student machine will have the client software installed by default. The student machine can perform operations such as incremental image extraction, importing and exporting images from USB drives, and restoring factory settings. Figure 4 Figure 5 The web management page allows teachers to perform mirror distribution operations.

[0028] In one specific embodiment of the present invention, a schematic diagram of the resource server is shown below. Figure 3 As shown, by Figure 3 It can be seen from the disk usage in this embodiment, and that there are two template machines in this embodiment, one storing the full electronic classroom image and the other storing the incremental electronic classroom image; there are four student machines, indicating that this electronic classroom is connected to four student machines. The number of users, two, indicates that there are two teachers. Figure 3 This indicates that the ongoing operation is two teachers distributing supplies to students.

[0029] Figure 4 Figure 5 Perform the image distribution operation for teachers. Figure 5 In the process, teachers select the available full electronic classroom images and incremental electronic classroom images on the web management page; after selection, the student computers will obtain the specified information technology innovation system image upon startup. Figure 4 The image displayed shows which image, terminal type, and power-on / off status of the different student computers in the classroom.

[0030] In one specific embodiment of the present invention, starting the full electronic classroom image and the incremental electronic classroom image obtained by the student terminal includes: modifying the script based on the domestically developed operating system to change the read-only mode mount of the domestically developed operating system's boot partition to a read-write mode mount; combining the downloaded domestically developed operating system files to obtain the root directory in which the domestically developed operating system can run; clearing the cached data in the root directory; and starting the root directory.

[0031] In one specific embodiment of the present invention, booting the full electronic classroom image and the incremental electronic classroom image obtained by the student terminal includes modifying the partition mounting mode and customizing the disk partition mode of the domestically developed operating system, as follows: Based on a modified script of a conventional domestically developed operating system, this method changes the read-only mount of the boot partition of the domestically developed operating system to a read-write mount, rewrites the domestically developed operating system files, and reorganizes the root directory of the domestically developed operating system. It specifies the system working directory to a specified disk partition; if data exists in the working directory, it is cleared, and the system boots. Among them, the process of rewriting the domestically developed operating system files and organizing the domestically developed operating system root directory is as follows: the domestically developed operating system files in the full electronic classroom image and the incremental electronic classroom image are combined to obtain the root directory in which the domestically developed operating system can run.

[0032] Customized disk partitioning modes include: Create at least three partitions on the disk. Partition 1 should be a vfat32 formatted system boot partition, with a minimum size of 3GB. Partition 2 is an ext4 formatted electronic classroom image partition, used to store the electronic classroom image and the internal operating system files for running the internal operating system. It is required to be no less than 16GB. Partition 3 is an ext4 formatted data file partition, used to store user files that need to be retained.
