The invention discloses a teaching method based on 3D scanning automatic spot drilling machining and a spot drilling machine, and belongs to the technical field of 3D scanning automatic spot drilling machine teaching. The teaching method comprises the steps that three-dimensional point cloud data of the surface of a workpiece are collected according to a preset sequence; segmenting workpiece data from the point cloud, registering the workpiece data with a workpiece standard CAD model, and establishing coordinate mapping; analyzing the diamond CAD model to obtain pose and size parameters of the diamond; then, the diamond parameters are converted into equipment control parameters through the coordinate mapping relation and an equipment kinematics model; and finally, generating a final teaching file according to the control parameters. According to the teaching method, full-automatic generation from three-dimensional scanning to machining teaching files is achieved, manual intervention is reduced, the problems that traditional spot drill teaching is low in efficiency and poor in precision are solved, automatic teaching is achieved through 3D scanning, PointNet network segmentation and CAD registration, spot drill machining efficiency and consistency are improved, and labor cost is reduced.

The present application relates to the technical field of computer program scheduling, specifically to storage task scheduling in data processing devices, and relates to a nursing experimental teaching file management system based on a distributed ledger. The system extracts a feature vector of a nursing experimental teaching file and inputs it into a cold and hot judgment model to output a cold and hot label of the file. The system performs differentiated storage scheduling according to the cold and hot label, distributes the hash address and complete data of the hot label file to full nodes for high-frequency block storage, distributes the complete data of the cold label file to archiving nodes for low-frequency persistent storage, and the full nodes retain the hash address of the cold label file and the physical location index pointer of the archiving nodes. The present application offloads the complete data of the cold label file with low-frequency access from the full nodes to the archiving nodes, reduces the disk occupied space of the full nodes, and avoids the decline of the block output and synchronization performance of the full nodes due to the expansion of historical archived data.

This application provides a method and system for intelligent interactive teaching of film and television based on a large model, belonging to the field of film and television teaching technology. This method integrates multiple functions into a single main interface, including teaching file management, playback settings, and handout export controls, enabling efficient management and utilization of film and television teaching files in various formats. The method can automatically parse video content using a large model and automatically generate subject tags and knowledge point tags, which are then linked with a big data knowledge base and exercise bank to form extended knowledge and exercise indexes, facilitating the organization and expansion of educational resources. Furthermore, it supports setting personalized teaching interaction trigger points based on these indexes, enhancing the interactivity and relevance of the teaching process. Finally, teachers can automatically generate and export teaching handouts based on all the above information, effectively improving the efficiency of handout production and the quality of teaching.

The invention relates to a space-adjustable teaching file cabinet, which comprises a double-door cabinet, the double-door cabinet comprises a small and medium piece cabinet and a large piece cabinet, the small and medium piece cabinet is internally provided with an adjustable partition plate frame assembly for separating storage space, and the partition plate frame assembly comprises a plurality of horizontal partition plate frame bottom plates and vertical partition plate frame partition plates; the partition plate frame bottom plates and the partition plate frame partition plates which are arranged in a crossed mode are matched to form a plurality of small and medium file storage spaces, an adjustable partition plate mechanism for separating the storage spaces is arranged in the large file cabinet, the partition plate mechanism comprises a plurality of horizontally-arranged partition bottom plates, and the partition bottom plates are in transmission connection with a partition bottom plate lifting mechanism. And the separation bottom plate is matched with the inner side wall of the large file cabinet to form a plurality of large file storage spaces. According to the space-adjustable teaching file cabinet, an improved double-door cabinet scheme combining small and medium file cabinets and large file cabinets is adopted, file data are classified and stored according to the external size, then the storage space in the cabinet is flexibly adjusted, and the space-adjustable teaching file cabinet has the advantages that the utilization rate of the internal space of the file cabinet is high, and file data storage and management are facilitated.
