Blackboards are familiar objects that usually appear in school classrooms. With the continuous changes and development of modern technology, blackboards are also constantly improving. Nowadays, the most common type of blackboard is a push-pull blackboard. Based on this composite blackboard, through the sensor technology of the Internet of Things, without changing any of the teacher's usage habits (using ordinary chalk and eraser to write and erase content on ordinary blackboards), the trajectory written on ordinary blackboards or whiteboards can be digitized in real time. The digital blackboard can be projected and enlarged in real time through existing projectors or other display devices in the classroom, and can also be synchronized in real time on the cloud or mobile phone.

The main advantages of smart interactive blackboard are:

1. Writing synchronization: Writing with regular chalk, smooth feel, moderate friction, even notes, clear lines, achieving real-time projection.

2. Environmental protection for eyes: High quality painted steel plates from internationally renowned brands, with panel and frame glossiness less than or equal to 12%, no obvious glare or reflection, effectively protecting students' vision.

3. Humanization: teachers can change the positions of the top, bottom, left and back (different models) of the blackboard according to actual needs, and use high-strength, moisture-proof and sound absorbing polystyrene foam to effectively improve the sense of writing without squeaking.

Overall architecture of intelligent interactive blackboard

The touch all-in-one machine is located in the middle, with fixed writing boards parallel to the touch all-in-one machine at both ends of the inner layer, and a sliding writing board on the outer layer. The touch all-in-one machine is partially installed; Double layered structure, with one end of the inner layer equipped with a fixed writing board parallel to the touch all-in-one machine, and the outer layer consisting of a sliding writing board with a padlock that can be freely opened and closed to ensure the safety of the touch all-in-one machine.

Through the above explanation, everyone should now have a basic understanding of the smart interactive blackboard.
