Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent teaching, and in particular relates to an intelligent integrated desktop applied to a classroom and a use method thereof. Background Art

[0002] With the continuous development and popularization of multimedia teaching or smart teaching, there are more and more audio and video teaching equipment placed on the classroom podium, such as desktop computers, notebooks, thin clients, desktop monitors, card readers, desktop controllers, gateways, central control, power boxes, amplifiers, gooseneck microphones, etc. In addition, with the development of smart teaching for dual-screen teaching, such as wireless projection mobile teaching, such as seminar-type classrooms, and taking the same class in different places (remote interactive teaching), etc., more and more teaching equipment will be needed for teaching. Each additional function requires the addition of corresponding teaching equipment, and the additional teaching equipment usually needs to be placed inside the podium or on the podium surface.

[0003] On the one hand, a large number of audio and video teaching equipment takes up a large amount of podium space, resulting in very little remaining space on the podium, which is inconvenient for teachers to use and also affects the aesthetics and cleanliness of the classroom environment; on the other hand, due to the complex connections between the various audio and video teaching equipment, when adding cabinets, it also involves the connection between the cabinets and the equipment placed on the podium, which not only has the problem of complex installation, but also reduces the reliability of the system and makes the system prone to failure; in addition, it also increases the complexity of teachers' use, resulting in lower usability and affecting teachers' enthusiasm for use.

Step 2, the intelligent integrated desktop regularly obtains the latest teacher ID information table, face database and teaching schedule from the remote management platform through the Ethernet communication interface; wherein the teaching schedule stores the following teaching information of each class: course start time, course end time, course ID and teacher ID; When the card reading module reads the IC card information inserted by the teacher through the IC card reader, the card reading module obtains the teacher ID information from the read IC card information, and then the card reading module uploads the read teacher ID information to the processor; the processor compares the read teacher ID information to see whether it is consistent with the teacher ID corresponding to the current course time in the teaching schedule, if they are consistent, it indicates that the teacher has the teaching authority, and the processor opens the authority corresponding to the teaching authority; When the face recognition and liveness detection module captures a face through the camera module, the face recognition and liveness detection module performs face recognition based on the face database, and obtains the currently detected teacher ID information based on the teacher ID information table; then, the card reading module uploads the read teacher ID information to the processor; the processor compares the read teacher ID information to see if it is consistent with the teacher ID corresponding to the current course time in the teaching schedule; if they are consistent, it indicates that the teacher has the teaching authority, and the processor opens the authority corresponding to the teaching authority; Step 3, when the smart teaching module is triggered to start, the smart teaching module obtains network teaching resources through the Ethernet communication interface and displays them; When the wireless screen projection module is triggered and started, the wireless screen projection module outputs the teaching content from two independent video output interfaces at the same time under the control of the LCD touch control or the remote control, thereby realizing dual-screen display of the teaching content, and the teaching content displayed on the dual screens is exactly the same; or, the wireless screen projection module outputs different teaching content from two independent video output interfaces under the control of the LCD touch control or the remote control, thereby realizing dual-screen display of the teaching content, and the teaching content displayed on the dual screens is different; When the remote interaction module is triggered and started, remote audio and video interaction between different classrooms, or audio and video interaction between a classroom and a main control room is carried out; When the normalized course recording module is triggered to start, the normalized course recording module starts recording the course and stores it locally or through a remote network; When the audio and video management module is triggered to start, the video input data of the local desktop / notebook, the wireless screen projection video input data, and the network video resource data are gathered into one point for integration, and then output from the corresponding audio and video output interface according to the classroom teaching requirements; When the liquid crystal touch module is triggered to start, the liquid crystal touch module performs reverse control on the external signal source, including: reverse control on the computer interface, that is, the capacitive touch screen transmits the detected teacher's instructions to the controlled computer through the network, thereby realizing reverse control on the computer interface; When the video switching module is triggered to start, the video switching module switches between the desktop or notebook teaching content, the screen projection teaching content and the cloud courseware teaching content according to the command;
