Monitoring camera based on smart classroom

Abstract

The invention relates to the field of monitoring cameras, in particular to a monitoring camera based on a smart classroom, which comprises a main body, a machine head, a mounting mechanism, a fixing mechanism, a reciprocating mechanism, a cleaning mechanism and a liquid adding mechanism, the limiting parts of the machine head can be conveniently and rapidly fixed through the arrangement of the fixing mechanism, multiple fixing parts do not need to be operated one by one, the fixing efficiency is improved, the machine head can be conveniently installed on the fixing mechanism through the arrangement of the installation mechanism, and disassembly and assembly are convenient; through the arrangement of the reciprocating mechanism, friction cleaning can be conveniently conducted on the area where the camera shooting part is located in a reciprocating mode, dust on a lens is removed, the definition of shot images is improved, through the arrangement of the cleaning mechanism, cleaning liquid beneficial to cleaning can be sprayed while the reciprocating mechanism operates, and therefore stubborn stains can be removed and the cleaning effects are improved; and through the arrangement of the liquid adding mechanism, cleaning liquid can be conveniently injected into the liquid storage part, and therefore normal operation of the cleaning mechanism is guaranteed.

Description

technical field [0001] The invention relates to the field of surveillance cameras, in particular to a surveillance camera based on a smart classroom. Background technique [0002] Surveillance camera is a semiconductor imaging device, which has the advantages of high sensitivity, anti-glare, small distortion, small size, long life, and anti-vibration. Surveillance camera security system. Currently, images are generated mainly from CCD cameras, and the stored charge can also be taken out to change the voltage, which is widely used because of its anti-vibration and impact characteristics. [0003] In order to facilitate the observation of the teachers and students in the smart classroom, it is generally used to install surveillance cameras at the corners of the classroom to observe the teaching situation. However, most of these surveillance cameras are designed in one piece and need to be completely fixed with nuts and bolts at one time. , and it is necessary to fix multiple...

[0003] In order to facilitate the observation of the teachers and students in the smart classroom, surveillance cameras are generally installed at the corners of the classroom to observe the teaching situation. However, most of these surveillance cameras are designed in one piece and need to be completely fixed with nuts and bolts at one time. , and it is necessary to fix multiple limit holes one by one, which reduces the fixing efficiency. In addition, the mirror position of a general camera is easily covered by dust after a long time of use, thus affecting the clarity of the recorded image
