Description

Technical Field

[0001] The present invention relates to the field of intelligent monitoring devices for cloud classrooms, and more particularly, to an intelligent monitoring device for cloud classrooms. Background Art

[0002] A cloud classroom is an online education platform built based on cloud computing technology, breaking the limitations of traditional education in terms of time and space. In a cloud classroom, teachers can use diverse teaching tools, such as online live lectures, recorded video courses, shared electronic courseware, etc., to carry out teaching activities. Real-time interaction can be achieved between students and teachers, and it is easy to realize activities like asking questions and answering, group discussions, and online tests. In addition, cloud classrooms also have powerful resource storage and management functions. Learning materials can be saved and retrieved at any time, and the learning progress can be accurately recorded, facilitating students' review and greatly enhancing the flexibility, efficiency, and personalization of education, bringing new opportunities for change and development to the field of education.

[0003] Currently, most cloud classroom monitoring devices mainly focus on basic monitoring functions. They can proficiently record videos and audio during classes, facilitating teachers' future review of courses and ensuring students' attendance. However, a significant drawback is the lack of an active reminder function. When students show signs of drowsiness, such as frequent yawning, nodding, or half-closed eyes, there is no corresponding mechanism to automatically detect such behaviors and respond. This means that as students become distracted, valuable teaching time may be wasted, and teachers may not be able to promptly notice these inattentive states, especially in large-scale online classes where it is difficult to closely monitor every student.

[0004] How to invent an intelligent monitoring device for cloud classrooms to improve these problems has become an urgent problem for those skilled in the art to solve. Summary of the Invention

Specific embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Example, refer to Figures 1 - 2, A cloud classroom intelligent monitoring device, including a base 1, a lower housing 2 fixedly connected to the top of the base 1, an upper housing 3 fixedly connected to the top of the lower housing 2, a rear cover 4 and a front cover 5 fixedly connected to the top of the upper housing 3. The rear cover 4 and the front cover 5 are connected by a buckle. It further includes: a reminder component, which is arranged inside the lower housing 2 and is used to remind the student status; a rotation component, which is arranged inside the upper housing 3 and the rear cover 4 and is used to control the rotation of the monitoring device; a connection component, which is arranged inside the rear cover 4 and is used to maintain the stable connection between devices. A speaker outlet and an air flow outlet 6 are provided on the outer side wall of the lower housing 2.

[0023] The reminder component includes a stabilizing plate 7 fixedly connected to the inner side wall of the lower housing 2. A first motor 8 is fixedly connected to the side wall of the stabilizing plate 7. A rotating sleeve 9 is sleeved on the output end of the first motor 8. Wind blades 10 are circumferentially arranged on the outer side wall of the rotating sleeve 9. The positions of the wind blades 10 correspond to the air flow outlet 6. A controller 12 is fixedly connected to the inner side wall of the lower housing 2. The first motor 8 is electrically connected to the controller 12. A speaker 11 is fixedly connected to the inner side wall of the lower housing 2. The speaker 11 is electrically connected to the controller 12.

[0024] It should be noted that: by setting the camera 26, the camera 26 captures the actions of students in front of the device and is used to analyze the status of students in learning. When behaviors such as the eyes of students being half-closed or lying prone on the table and not concentrating on listening to the class appear, a text reminder will appear on the screen for student-teacher interaction to prevent students from being in a state of inattention for a long time. By setting the light sensor 27 with the model number TSL2561, the brightness of the environment where the device is located is captured. If the brightness of the environment is insufficient, a text reminder will appear on the screen for student-teacher interaction to prevent the learning environment from being too dark or too bright, resulting in the phenomenon that the eyes are prone to fatigue. By setting the microphone 28, students can communicate with the teacher in the cloud classroom through the microphone 28 by audio, which is convenient for students to answer questions raised by the teacher in the cloud classroom.

[0025] Since the controller 12 is electrically connected to the first motor 8, the controller 12 supplies power to the first motor 8. The output end of the first motor 8 drives the rotating sleeve 9 to rotate, driving the wind blades 10 to do circular motion. The wind blades 10 drive the air flow from the inside of the lower housing 2, through the air flow outlet 6, to the external environment.

[0026] Refer to Figures 3 - 5The rotating assembly includes a second motor 21 fixedly connected to the inner side of the top of the upper shell 3, a pinion 22 is fixedly sleeved on the output end of the second motor 21, a rotating member 23 is rotatably connected to the upper shell 3, a ring gear 24 is fixedly connected to the outer wall of the rotating member 23, the top of the ring gear 24 is fixedly connected to the rear cover 4, a hemispherical cover 25 is arranged on the inner side of the front cover 5, the ring gear 24 is located on the inner side of the upper shell 3, the ring gear 24 is meshed with the pinion 22, a camera 26 is embedded on the hemispherical cover 25, and light sensors 2 are arranged on the upper and lower sides of the camera 26 7 and microphone 28, the rotating assembly also includes a circuit board 29 fixedly connected to the side wall of the hemispherical cover 25, a fixing ring 30 and a third motor 31 are fixedly connected to the circuit board 29, an outer wall of the third motor 31 is fixedly connected to a push frame 32, an output end of the third motor 31 is fixedly sleeved with a fitting block 33, the fitting block 33 is arranged in a rectangular parallelepiped shape, the fitting block 33 passes through the fixing ring 30, an end of the fitting block 33 is fitted with the inner wall of the rear cover 4, the outer wall of the fixing ring 30 is fixedly connected to a rotating shaft 34, and the rotating shaft 34 is rotatably connected to the inner wall of the rear cover 4.

[0027] It should be noted that: the output end of the second motor 21 rotates, driving the pinion 22 to rotate, driving the ring gear 24, the rotating member 23 and the rear cover 4 to rotate, thereby driving the hemispherical cover 25 to rotate through the circuit board 29, and driving the camera 26 to rotate in the horizontal direction, which is used to capture the horizontal position of the student's face, so that the student's facial expression can be observed more clearly. By controlling the rotation of the output end of the third motor 31, when the third motor 31 rotates, it drives the engaging block 33 to rotate. Since the rear cover 4 is fixed on the rotating member 23, the third motor 31 body that is subjected to the reaction force begins to rotate, and drives the fixing ring 30 to rotate on the rear cover 4 through the circuit board 29, driving the camera 26 to rotate in the vertical direction, which is used to capture the vertical movement of the student's face, which is conducive to observing the student's facial expression.

[0028] Reference Figures 6 - 9, the connecting component includes a support shaft 41 rotatably connected to the inner side wall of the rear cover 4. A lever 42 is rotatably connected to the support shaft 41. The end of the lever 42 is arranged in an arc shape. A cylinder 43 is fixedly connected to the inner side wall of the rear cover 4. A piston 44 is arranged inside the cylinder 43. A one-way valve is arranged on the piston 44. A push rod 45 is fixedly connected to the top of the piston 44. A push plate 46 is fixedly connected to the top of the push rod 45. A partition plate 47 is fixedly connected to the inner side wall of the cylinder 43. A return spring 48 is fixedly connected to the top of the partition plate 47. An air outlet seat 49 is fixedly connected to the end of the piston 44. A push spring 51 is fixedly connected to the top of the air outlet seat 49. A sealing ball 50 is fixedly connected to the top of the push spring 51. An air pipe 52 is sleeved on the end of the air outlet seat 49. The connecting component further includes a power cord 53 arranged on the upper housing 3. The air pipe 52 is located inside the power cord 53. A connecting seat 54 is arranged at the end of the power cord 53. A plug 55 is fixedly connected to the connecting seat 54. A support seat 56 is arranged inside the plug 55. A plurality of contacts are arranged on the support seat 56. An airbag 57 is arranged inside the support seat 56. The airbag 57 is communicated with the air pipe 52. An air outlet end 58 is arranged at the bottom of the airbag 57. A friction block 59 is fixedly connected to the top of the airbag 57. The air outlet end 58 extends into the support seat 56, and the support seat 56 squeezes the air outlet end 58.

[0029] It should be noted that when the student moves downward following the movement of adjusting the sitting posture and other actions, causing the camera 26 to move downward with the student, the third motor 31 drives the push frame 32 to squeeze the end of the lever 42, driving the lever 42 to rotate on the support shaft 41, pushing the push plate 46 to squeeze the piston 44 through the push rod 45. The piston 44 squeezes the air inside the cylinder 43, pushing the sealing ball 50 to overcome the elastic force of the push spring 51, injecting the air into the airbag 57 through the air pipe 52, causing the airbag 57 to expand. After expansion, the airbag 57 deforms, squeezing the friction block 59, causing the friction block 59 to protrude outward, increasing the friction between the plug 55 and the external contact surface.

[0030] In this embodiment, by inserting the plug 55 into the interactive device of the cloud classroom to connect the device, the camera 26 of the device continuously captures the facial features of the student, identifies the state of the student when participating in the cloud classroom. When the student shows a state of inattention, the controller 12 powers the first motor 8, causing the wind blade 10 to rotate, controlling the direction of the airflow blowing towards the student, reminding the student to get out of the inattentive state. This reminder method is relatively gentle and causes less interference to the surrounding environment. The airflow can also help the sleepy student regain their spirits, which is beneficial to helping the student improve their learning state.

[0031] When the student moves the camera 26 downward due to actions such as adjusting the sitting posture, this action drives the push frame 32, and injects air into the interior of the airbag 57 by squeezing the piston 44, causing the airbag 57 to expand. The expanded airbag 57 squeezes the friction block 59, causing the friction block 59 to protrude outward, increasing the friction force between the plug 55 and the contact surface of the cloud classroom interaction device, preventing the device from experiencing relative displacement between the plug 55 and the device it is connected to due to external force touching the power cord 53 during long-term use, and preventing abnormal situations such as unstable connections, further ensuring the coherence and efficiency of teaching activities.

[0032] It should be noted that the specific model and specifications of the motor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method uses the existing technology in the field, so it will not be elaborated in detail here.

[0033] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
