Regarding smart classrooms, for vocational colleges, it means a change in teaching philosophy, teaching methods, teaching tools, and learning methods. Proper use can effectively improve teaching quality, teaching efficiency, and learning outcomes. To carry out the construction of smart classrooms, it means systematically classifying and managing data. The key is to connect various subsystems and devices to achieve the construction of a smart campus in all scenarios. In addition, traditional campus management also has the following common problems:
1. There are numerous campus devices, making it difficult to achieve unified intelligent perception, control, and management;
2. Poor teacher-student interaction, traditional multimedia classrooms usually have only one teacher explaining, making it difficult to achieve interactive learning among students;
3. The wiring is complex and maintenance expenses are high; The complex wiring often leads to equipment malfunctions, which brings huge maintenance costs for later maintenance.
In response to the above issues, Bijie Internet adopts a multi screen collaborative smart classroom solution to create a group discussion smart classroom scenario for vocational colleges. It adopts a solution of display devices+IP networking+multimedia collaboration system (BJ66 interactive version/BJ80 interactive version), supporting group communication, multi screen interaction, achievement display, annotation and review functions, and can be integrated with the classroom control system and classroom recording system. At the same time, it can provide a unified management platform, support large-scale deployment, and facilitate remote management by school operation and maintenance personnel.
The BJ66 interactive version and BJ80 interactive version meet the requirements of smart classrooms for various functions such as wireless screen casting, multi screen synchronization, real-time broadcasting, arbitrary screen control, and arbitrary personnel screen casting.
Build a multi screen interactive group teaching system with interactive touch screens for teachers and student group screens. Adopting multi screen interactive technology, supporting various interactive functions such as dynamic annotation and split screen preview. Combining multiple teaching modes such as seminar based, group based, inquiry based, blended learning, etc., makes teaching more scientific, easy, and effective!

The teacher can use the drag and drop function on the main screen to display multiple group screens simultaneously on the main screen. The main screen can display up to 6 groups’ screen images simultaneously.
Teachers can synchronize and push the main screen to each group’s sub screen in the form of broadcasting.
Teachers can pull the screen of a certain group to the main screen for display, and at the same time broadcast the main screen image to other groups for sharing on the same screen.
02 Wireless screen mirroring
The product (BJ66 Interactive Edition/BJ80 Interactive Edition) supports mainstream wireless screen casting protocols, and teachers and students can cast their devices without installing any software. It is compatible with AirPlay, Miracast, WiDi, Googlecast, HUAWEI Cast+, and BJCast screen casting protocols;
03Web centralized control management
Support centralized device management and maintenance, remote control and management of network devices for easy unified management and deployment by schools;
04 Central control center
It can be integrated and docked with the central control system to achieve the integrated and linked use of multimedia teaching information equipment. It can control various functions of group interaction with one click, which is more convenient and efficient, and improves teaching quality and efficiency;
05 Recording and broadcasting docking
Can provide RTSP interface, which can be integrated with the school recording and broadcasting system to achieve recording and storage of teaching screen projection audio and video, helping teachers to review the classroom and students to review the old and learn new;
