Description

Technical Field

[0001] This invention belongs to the field of intelligent teaching technology, specifically an intelligent teaching aid device for monitoring the attention of primary school students. Background Technology

[0002] A smart teaching aid device for monitoring primary school students' attention refers to an intelligent system deployed in the classroom that collects data such as students' facial expressions, eye movements, and head postures in real time through cameras or wearable sensors, and uses artificial intelligence algorithms to analyze their concentration and inattentiveness. It can provide real-time feedback on the distribution of attention to teachers, helping them to dynamically adjust the pace of teaching and interaction methods, thereby achieving quantitative management of classroom concentration and personalized teaching assistance.

[0003] For example, CN221949479U discloses a Chinese language teaching aid device, including a teaching board mounted on a teaching aid frame, and a convenient storage component on the teaching aid frame; the convenient storage component includes an outer storage frame. This Chinese language teaching aid device, by incorporating the convenient storage component, places the teaching board and the movable support bracket supporting the teaching board inside the outer storage frame. The bottom of the movable support bracket is fitted with a support base plate that rests on a flat surface. The contact surface of the support base plate has a rubber anti-slip raised layer to prevent slippage. The top, front, and rear ends of the outer storage frame have handles for easy carrying when the teaching board and movable support bracket are folded up. All of these features facilitate storage and operation, allowing the teaching board and movable support bracket to be folded up easily during outdoor teaching, improving convenience. However, in actual use, it was found that most current attention monitoring devices use a combination of smart cameras and algorithms. But in practice, most only use a single camera for monitoring, transmitting the detected signal to a multimedia terminal on the podium. Teachers can only observe from the podium, which is detrimental to the overall teaching rhythm in the classroom. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent teaching aid device for monitoring the attention of primary school students in order to solve the problems mentioned above.

[0005] The technical solution adopted in this invention is as follows: A smart teaching aid device for monitoring the attention of primary school students, wherein the distributed installation unit and the monitoring camera constitute a segmented monitoring integrated structure and are installed on the top of the classroom; multiple monitoring cameras are inserted and installed on the side surface of the distributed installation unit through holes; an information bus is provided on the upper side surface of the monitoring camera, and the information bus transmits the signals generated by the monitoring integrated structure to an external prompting component, which includes a block light, a sound box, and a multimedia screen; the information bus is an LED matrix light box that can emit light, a sound box is provided on the side of the block light, and a multimedia screen is provided on the end of the block light opposite the sound box.

[0006] By adopting the above technical solution, operators utilize distributed installation units as the foundation for the entire device. These units are equipped with multiple monitoring cameras, each containing a corresponding monitoring algorithm to monitor students below and make inferences based on their movement signals. The information bus serves as the overall wiring structure, connecting the entire monitoring structure to the outside world and providing power transmission and signal transmission. When a signal is transmitted to the other end, it is displayed on a zone light, indicating the corresponding area where students are inattentive, and simultaneously triggering a speaker to provide a reminder. The multimedia screen is remotely controllable. Through this system, operators can monitor students' attention levels in real time using the top-mounted monitoring system, identifying areas where inattention is occurring, facilitating teacher movement and on-site correction. Simultaneously, corresponding prompting components further enhance student concentration, better aligning with the teaching pace.

[0007] The distributed installation unit is a lightweight aluminum alloy frame that is bolted to the ceiling. Its internal wiring is complex, primarily used for signal transmission and powering the monitoring cameras. The monitoring cameras use mainstream domestic monitor signals, but their image signals are transmitted outward via an information bus to a computer processor. Combined with algorithms, this is mainly used to monitor the movement of the student's torso, head, and other body parts to help determine their attention.

[0008] After the information bus transmits the signal back, when the system detects a change at the corresponding location, it transmits the signal to the zone lights via the information bus. Since there is a one-to-one correspondence between the positions on the distributed installation units and the positions on the zone lights, a light can be turned on to alert the teacher when someone loses focus in the corresponding area. Simultaneously, the speaker will emit a short, sharp sound to remind all students to maintain their attention. The multimedia screen is connected to the computer and can be controlled remotely.

[0009] In a preferred embodiment, the distributed installation unit is connected to a connecting rail rod through an opening, and the distributed installation unit is connected to a mounting frame through the connecting rail rod.

[0010] By adopting the above technical solution, the connecting track rod, as a connecting rod, is installed at its top with the aid of a pad. After the connecting track rod is installed, a specific mounting frame for installing the monitoring camera is set below it. The mounting frame is a frame structure mainly used to solve the angle problem of the monitoring camera installation.

[0011] In a preferred embodiment, an angle adjustment unit is provided at the bottom end of the connecting track rod, and a connecting shaft is connected to the bottom end of the angle adjustment unit. The angle adjustment unit is connected to a mounting bracket through the connecting shaft.

[0012] By adopting the above technical solution, the connecting shaft on the mounting bracket is a shaft, and the top of the connecting shaft is connected to the inside of the angle adjustment unit. The angle adjustment unit contains a miniature servo motor and a corresponding worm gear structure. When a monitoring camera is installed, the angle adjustment unit can be remotely controlled to monitor changes in the camera's angle, further reducing the monitoring range.

[0013] In a preferred embodiment, a mounting flange is provided on the side of the mounting frame. The mounting flange is a flange with multiple round holes. The mounting flanges are symmetrically distributed at both ends. A connecting flange shaft is provided in the middle of the mounting flange. A monitoring camera is installed on the mounting frame through the mounting flange and the connecting flange shaft.

[0014] By adopting the above technical solution, and with the help of the mounting flange and fixing bolts, the corresponding deflection angle of the monitoring camera can be changed to a certain extent in the vertical direction, and precise and fine adjustment can be achieved.

[0015] In a preferred embodiment, the mounting flange is fitted with a fixing bolt through an opening.

[0016] By adopting the above technical solution, after the angle is deflected, the mounting flange and the connecting flange shaft are connected and fixed by fixing bolts.

[0017] In a preferred embodiment, the connecting flange shaft is connected to a monitoring camera via a connecting intermediate rod at its bottom end.

[0018] By adopting the above technical solution, the connecting intermediate rod mainly plays a connecting role, and by utilizing the rigidity of the lightweight rod, the monitoring camera is fixed as much as possible on a certain structural line.

[0019] In a preferred embodiment, a strobe light is provided at the bottom of the monitoring camera.

[0020] By adopting the above technical solution, the strobe light is set at the bottom of the monitoring camera. When the monitoring camera detects a certain degree of attention deviation at the corresponding position, the strobe light will flash under the control of the computer and through the signal transmission of the information bus to complete the second prompt.

[0021] In a preferred embodiment, a wire is provided on the side end of the strobe lamp.

[0022] By adopting the above technical solution, the wire is mainly used to achieve signal synchronization with the monitoring camera.

[0023] In a preferred embodiment, the monitoring camera is provided with a wire for connecting to the outside world, and the strobe light is connected to the monitoring camera via the wire.

[0024] By adopting the above technical solution, the monitoring camera is mainly controlled by an external information bus to monitor the camera and the corresponding strobe light.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In this invention, the distributed installation unit is a lightweight aluminum alloy frame, fixed to the ceiling with bolts. Its internal wiring is complex, primarily used for signal transmission and powering the monitoring cameras. The monitoring cameras use mainstream domestic monitor signals, but their image signals are transmitted outward via an information bus to a computer processor. Combined with algorithms, this is mainly used to monitor the movement of the student's torso, head, and other body parts to help determine their attention.

[0026] After the information bus transmits the signal back, when the system detects a change at the corresponding location, it transmits the signal to the zone lights via the information bus. Since there is a one-to-one correspondence between the positions on the distributed installation units and the positions on the zone lights, a light can be turned on to alert the teacher when someone loses focus in the corresponding area. Simultaneously, the speaker will emit a short, sharp sound to remind all students to maintain their attention. The multimedia screen is connected to the computer and can be controlled remotely.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figure 1-4 , Example: A smart teaching aid device for monitoring primary school students' attention. A distributed installation unit 1 and monitoring cameras 2 form a segmented monitoring integrated structure and are installed on the top of the classroom. Multiple monitoring cameras 2 are inserted and installed on the side surface of the distributed installation unit 1 through holes. An information bus 3 is provided on the upper side surface of the monitoring cameras 2. The information bus 3 transmits the signals generated by the monitoring integrated structure to an external prompting component. The external prompting component includes a block light 4, a sound box 5, and a multimedia screen 6. The information bus 3 is an LED matrix light box that can emit light. A sound box 5 is provided on the side of the block light 4, and a multimedia screen 6 is provided on the end of the block light 4 opposite to the sound box 5.

[0031] The operator uses the distributed installation unit 1 as the base for the entire device. Multiple monitoring cameras 2 are installed on the distributed installation unit 1, each equipped with a corresponding monitoring algorithm to monitor students below and make inferences based on their movement signals. The information bus 3 serves as the overall wiring structure, connecting the entire monitoring structure to the outside world and providing power transmission and signal transmission. When a signal is transmitted to the other end, it is displayed on the block light 4, showing the corresponding area where students are distracted, and simultaneously activating the speaker 5 to provide a reminder. The multimedia screen 6 is a multimedia screen that can be controlled by a remote control. Through this system, the operator can use the monitoring system at the top to monitor students' attention in real time and identify areas where attention is being lost, facilitating teacher movement and on-site correction. Simultaneously, corresponding prompting components further enhance students' concentration and better match the teaching pace.

[0032] The distributed installation unit 1 is a lightweight aluminum alloy frame that is bolted to the ceiling. Its internal wiring is complex, primarily used for signal transmission and powering the monitoring camera 2. The monitoring camera 2 uses a mainstream domestic monitor signal, but its image signal is transmitted outward via information bus 3 to the computer processor. Combined with algorithms, it is mainly used to monitor the movement of the student's torso, head, and other body parts to help determine attention levels.

[0033] After the information bus 3 transmits the signal back, when the system detects a change at the corresponding location, it transmits the signal to the block light 4 via the information bus 3. Since there is a one-to-one correspondence between the positions on the distributed installation unit 1 and the positions on the block light 4, when students lose focus in the corresponding area, the light will illuminate to alert the teacher. Simultaneously, the speaker 5 will emit a short, sharp sound to remind all students to maintain their attention. The multimedia screen 6 is connected to the computer and can be controlled remotely.

[0034] The distributed installation unit 1 is connected to a connecting rail rod 101 through pre-drilled holes. The distributed installation unit 1 is then connected to a mounting frame 7 via the connecting rail rod 101. The connecting rail rod 101, acting as a connecting rod, has its top secured with a pad. After the connecting rail rod 101 is installed, the mounting frame 7, a frame structure, is positioned below it to accommodate the monitoring camera 2. The mounting frame 7 is primarily used to address the angle issue during the installation of the monitoring camera 2.

[0035] An angle adjustment unit 8 is installed at the bottom of the connecting track rod 101. A connecting shaft 703 is connected to the bottom of the angle adjustment unit 8, and a mounting bracket 7 is connected to the angle adjustment unit 8 via the connecting shaft 703. The connecting shaft 703 on the mounting bracket 7 is a shaft, and its top end is connected to the inside of the angle adjustment unit 8. The angle adjustment unit 8 contains a miniature servo motor and a corresponding worm gear structure. When a monitoring camera 2 is installed, changes in the angle of the monitoring camera 2 can be controlled remotely via the angle adjustment unit 8, further reducing the monitoring range.

[0036] Mounting bracket 7 has mounting flanges 701 on its side. Mounting flanges 701 are flanges with multiple round holes, symmetrically distributed at both ends. A connecting flange shaft 202 is located in the middle of the mounting flanges 701. The monitoring camera 2 is mounted on the mounting bracket 7 via the mounting flanges 701 and the connecting flange shaft 202. Using the mounting flanges 701 and the fixing bolts 702, the vertical deflection angle of the monitoring camera 2 can be varied to a certain extent, achieving precise and fine adjustment.

[0037] Mounting flange 701 is fitted with fixing bolts 702 through pre-drilled holes. After the angle is deflected, the mounting flange 701 and the connecting flange shaft 202 are connected and fixed together by fixing bolts 702.

[0038] The connecting flange shaft 202 is connected to the monitoring camera 2 via the connecting intermediate rod 201 at its bottom end. The connecting intermediate rod 201 mainly serves a connecting function, using the rigidity of the lightweight rod to fix the monitoring camera 2 as much as possible on a certain structural line.

[0039] A strobe light 203 is installed at the bottom of the monitoring camera 2. When the monitoring camera 2 detects a certain degree of attention deviation at the corresponding location, the strobe light 203 will flash under the control of the computer and through the signal transmission of the information bus 3, thus providing a second prompt.

[0040] A wire 204 is provided on the side of the strobe light 203. The wire 204 is mainly used to synchronize the signal with the monitoring camera 2.

[0041] The monitoring camera 2 is equipped with a wire for connecting to the outside world, and the strobe light 203 is connected to the monitoring camera 2 via the wire 204. The monitoring camera 2 is mainly controlled by the external information bus 3 to monitor the camera and the corresponding strobe light.

[0042] The implementation principle of this invention's intelligent teaching aid device for monitoring primary school students' attention is as follows: The operator uses a distributed installation unit 1 as the foundation for the entire device. Multiple monitoring cameras 2 are installed on the distributed installation unit 1, each equipped with a corresponding monitoring algorithm to monitor students below and make inferences based on their movement signals. The information bus 3 serves as the overall wiring structure, connecting the entire monitoring structure to the outside world and providing power transmission and signal transmission. When a signal is transmitted to the other end, it is displayed on the area light 4, showing the corresponding area where students are distracted, and simultaneously activating the speaker 5 to provide a reminder. The multimedia screen 6 is a multimedia screen that can be controlled by a remote control. Through this system, the operator can use the monitoring system at the top to monitor students' attention in real time and identify areas where attention is being lost, facilitating teacher movement and on-site correction. Simultaneously, corresponding prompting components further enhance students' concentration and better match the teaching pace.

[0043] The distributed installation unit 1 is a lightweight aluminum alloy frame that is bolted to the ceiling. Its internal wiring is complex, primarily used for signal transmission and powering the monitoring camera 2. The monitoring camera 2 uses a mainstream domestic monitor signal, but its image signal is transmitted outward via information bus 3 to the computer processor. Combined with algorithms, it is mainly used to monitor the movement of the student's torso, head, and other body parts to help determine attention levels.

[0044] After the information bus 3 transmits the signal back, when the system detects a change at the corresponding location, it transmits the signal to the block light 4 via the information bus 3. Since there is a one-to-one correspondence between the positions on the distributed installation unit 1 and the positions on the block light 4, when students lose focus in the corresponding area, the light will illuminate to alert the teacher. Simultaneously, the speaker 5 will emit a short, sharp sound to remind all students to maintain their attention. The multimedia screen 6 is connected to the computer and can be controlled remotely.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
