Description

Technical Field

[0001] The present application relates to the technical field of smart classrooms, and specifically to a monitoring device for smart classrooms. Background Art

[0002] A smart classroom refers to a new type of classroom that uses modern information technologies such as the Internet of Things, cloud computing, and big data to make the teaching environment, teaching resources, and teaching activities intelligent, networked, and digitized. At this stage, surveillance cameras are usually installed inside the classroom to monitor the equipment in the classroom and protect the safety of students.

[0003] Patent No. CN 213629654 U discloses an examination monitoring device for a smart classroom, including a mounting seat, a protective shell, a pressing head and an airbag bag, etc. The mounting seat is designed at the end of the card seat to avoid the monitoring device being directly fixed by bolts at a certain position on the wall during use, which is inconvenient to disassemble or install during maintenance and inconvenient to operate. The mounting plate and the mounting seat can be fixed by bolts, and the end of the card seat is embedded in the interior of the mounting seat after fixing. The connecting rod and the card seat are rotated to clamp the card plate in the first card slot, and the pressing head is pressed tightly in the first card slot by the elastic deformation of the spring in the groove, which is convenient for the end of the card seat to be fixed with the mounting seat. The internal tight connection is convenient for installation and use, and it is easy to disassemble during maintenance, which solves the problem that it is directly fixed by bolts during installation and is inconvenient to disassemble or install during maintenance. At the same time, a protective shell is designed on the outer surface of the monitoring device body to avoid inconvenience in protecting the outer surface of the device during use, and it is easy to be deformed and damaged when impacted by the outside world. When an external object hits the surface of the protective shell during use, the airbag bag can be elastically deformed by the protective shell so that the protective shell is in a buffering state, rebounds against the impacted object, reduces the impact, and is not easy to be deformed and damaged, which solves the problem that it is easy to be deformed and damaged when impacted by external objects during use.

[0004] However, in use, there are the following defects:

[0005] Although a card plate and a card slot are used to facilitate the disassembly of the camera, since the camera is fixedly installed at a certain position on a wall, blind spots will be created during the monitoring process, affecting the actual use effect.
