Automatic monitoring device for teaching

Abstract

The invention discloses an automatic monitoring device for teaching. The automatic monitoring device comprises a motor arranged on a platform wall, a camera driven by the motor to rotate and a foot pad arranged on the platform surface; the motor is internally provided with a first microcontroller used for controlling the motor to rotate and a first bluetooth module connected with the first microcontroller; the foot pad comprises a plurality of air bags arranged at intervals and hydraulic bags containing clean water; a circuit board is arranged in a first ball bag and is provided with a touch switch, a second microcontroller storing the rotating angle and a second bluetooth module connected with the second microcontroller to be used for communication with the first bluetooth module, and thesecond microcontroller and the second bluetooth module are connected with the touch switch in series; the first ball bag is provided with an elastic block capable of pressing the touch switch; and all hydraulic bags communicate with each other, and one side of the foot mat is provided with a water outlet pipe communicating with the hydraulic bags. By means of the automatic monitoring device, orienteering rotation for monitoring can be achieved along with walking of a teacher.

Description

technical field [0001] The invention relates to the field of teaching equipment, in particular to an automatic teaching monitoring device. Background technique [0002] In order to enable students to make full use of classroom time for learning, most schools now install cameras in classrooms, so that special personnel can monitor the learning situation of students in each classroom through the images sent back by the cameras. [0003] However, the current cameras are all fixedly installed at a certain position in the classroom, and the shooting angles are fixed, so there will inevitably be dead spots, and students sitting in corners cannot be monitored. Moreover, the person watching the surveillance image is not in the classroom, so it is not easy to find the different learning status of each student in a certain classroom. Instead, it is the teacher who is teaching in the classroom, because standing on the podium can clearly see which students are in the classroom. Which s...

[0003] However, the current cameras are all fixedly installed at a certain position in the classroom, and the shooting angles are fixed, so there will inevitably be dead spots, and students sitting in corners cannot be monitored.

Moreover, the person watching the surveillance image is not in the classroom, so it is not easy to find the different learning status of each student in a certain classroom. Instead, it is the teacher who is teaching in the classroom, because standing on the podium can clearly see which students are in the classroom. Which students did not listen carefully to the class

Although there is that kind of rotatable camera now, this kind of camera is not only expensive, but also the rotation of the camera is periodic, which makes its rotation purposeless
