[0002] Educational information resources are valuable assets that help teaching and learning. They cover various teaching courseware, online courses, academic materials, etc., in various forms and from a wide range of sources. They can not only provide rich materials for teachers to prepare lessons and give lectures, but also meet students' needs for independent learning and knowledge expansion, and play a key role in promoting educational modernization and improving education quality.

[0003] The Chinese invention patent application with application number 202210685310.6 discloses an intelligent interconnected educational resource sharing system: including a course acquisition module, a class server, a school-level server, a regional-level server and a mobile APP compatible with the system. The system workflow is as follows: S1. The course acquisition module realizes the collection of actual teaching information, and transmits the collected audio and video information to the class server to generate video teaching resources for related courses; S2. The class server sends the generated video teaching resources of the relevant courses to the school-level server, and relevant teachers form a teaching resource rating group to evaluate and discuss the uploaded course video teaching resources, and recommend excellent video teaching resources; S3. After recommendation, the more excellent video teaching resources are uploaded to the regional-level server, and recommended and displayed in the regional-level server for teachers and students in the area to download and watch. The remaining video teaching resources that are not recommended are displayed in the corresponding school-level server for corresponding teachers and students to study and discuss.

[0004] However, those skilled in the art can think of reducing the differences in the levels of educational information resources in different regions by sharing educational information resources, but there is currently no technology specifically designed to realize this concept.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: In a first aspect, a regional education information resource sharing system comprises: The cloud database is used to receive, manage and store file contents; the interactive platform is used to input user identity information, and based on user identity information verification, provide cloud database access rights to users with verified identity information; the evaluation module is used to traverse the file contents stored in the cloud database and evaluate the recommendation index of each file content; The evaluation logic of the recommendation index of the file content in the evaluation module is expressed as follows: ; Where: is the recommendation index of the file content; The total amount of file content operation types; is the number of operations of the pth operation type; is the duration of the qth operation; for The longest operation duration; The configuration weight for the pth operation type; is the normalization factor; Among them, the total number of file content operation types Including reading, downloading, , the configuration weight corresponding to the read operation pointed to by p is always greater than the configuration weight corresponding to the download operation, and the normalization factor >0; The coordination module is used to obtain the evaluation results of the recommendation index of each file content in the evaluation module, and coordinate the storage location of the file content in the cloud database based on the evaluation results; the output module is used to obtain the file content coordination results in the coordination module, generate a message with the file content coordination results as the message content, and output it; the refresh module is used to refresh the system operation; The cloud database is interactively connected to a classification unit and a cleaning unit at a lower level through a wireless network, the cloud database is interactively connected to an interactive platform through a wireless network, the interactive platform is interactively connected to the cleaning unit through a wireless network, the interactive platform is interactively connected to an evaluation module, a coordination module and a refresh module through a wireless network, and the refresh module is interactively connected to a monitoring unit through a wireless network.

[0008] Furthermore, the file content in the cloud database is manually uploaded by the online user in the interactive platform. When the cloud database receives the file content, it synchronously identifies the format of the file content. The cloud database is provided with submodules at the lower level, including: A classification unit, used for obtaining the format of each file content received by the cloud database, and creating a differentiated storage interval of corresponding data in the cloud database based on the number of types of file content formats; A cleaning unit, used to traverse the file contents stored in the storage intervals of each partition and clean the file contents; Among them, after the classification unit creates the differentiated storage intervals, it applies the differentiated storage intervals to differentiate the file content received by the cloud database so that the format of the file content stored in each differentiated storage interval is the same.
