Description

Technical Field

[0001] This invention belongs to the field of smart education equipment technology, specifically relating to a smart desk that integrates paperless examination and health monitoring functions. Background Technology

[0002] With the deepening of educational informatization, the digital transformation and upgrading of teaching, assessment, and management have become an inevitable trend. However, in current teaching practices, especially in the crucial examination process, there are still many pain points such as low efficiency, waste of resources, and delayed data feedback.

[0003] Traditional paper-based examinations rely on cumbersome manual processes: after the exam, all paper papers must be collected, scanned one by one by designated personnel, and then uploaded in batches to a dedicated online marking system (such as Zhixue.com or Qitian Network). This process not only consumes significant manpower, resources, and time, leading to prolonged feedback cycles and affecting the timeliness of teaching assessments, but also carries risks of paper damage, omissions, and information confusion during scanning and circulation, making it difficult to fully guarantee the fairness and accuracy of the examination. Furthermore, the printing, storage, and management of paper papers also result in significant resource consumption and environmental burden.

[0004] Currently, while there are some solutions related to electronic or smart desks, such as those focusing on height adjustment, digitized textbook content, or basic electronic display functions, these solutions are relatively limited in functionality and fail to deeply integrate with the complete paperless examination process. They typically lack a systematic design for exam-specific functions (such as anti-cheating monitoring, seamless integration with existing marking platforms, and AI-assisted grading), and they do not consider real-time monitoring of students' health (such as emotion recognition and fatigue warnings) as an important component for improving the exam experience and learning outcomes. Summary of the Invention

[0005] The purpose of this invention is to provide a smart desk that integrates paperless examination and health monitoring functions, overcoming the aforementioned technical problems in the prior art.

[0006] Therefore, the technical solution provided by the present invention is as follows:

[0007] A smart desk integrating paperless examination and health monitoring functions includes:

[0008] The desk body includes an actuator for adjusting the desk height and the desktop tilt angle;

[0009] The multimodal sensing unit includes an image acquisition module, an infrared temperature sensor, and a pressure sensor. The image acquisition module is used to acquire facial image information of students, the infrared temperature sensor is used to acquire ambient temperature, and the pressure sensor is used to detect the force state on the desktop.

[0012] The paperless examination unit is used to perform dynamic rendering of encrypted test papers, real-time AI grading of objective questions, and identification of abnormal examination behavior.

[0013] The health monitoring unit is used to receive student facial image information collected by the image acquisition module, perform emotion analysis on the facial images using a convolutional neural network model, and determine the student's fatigue state or poor sitting posture by combining pressure sensor data, and send a signal to the control host.

[0014] The touch screen, multimodal sensing unit, and actuator are all electrically connected to the control host. The control host controls the actuator based on the signal sent by the health monitoring unit to adjust the main body of the desk.

[0020] The data preprocessing unit is used to extract features from the facial image data, filter the pressure data, and correct the temperature data.

[0021] The processing and decision-making unit is used to perform paperless examination processing, student attention judgment, and posture recognition, respectively.

[0022] The decision and control unit is used to output reminder instructions or structural adjustment execution instructions based on the processing results.

[0023] Furthermore, the actuator includes an electric telescopic rod, an upper support plate, an adjustment panel, and a telescopic cylinder. The upper support plate is located below the top plate and the electric telescopic rod and is fixedly connected to both. The control host controls the electric telescopic rod to finely adjust the height of the upper support plate.

[0024] The telescopic cylinder is located on the lower end face of the adjustment panel, and the control host adjusts the angle of the adjustment panel by controlling the telescopic cylinder.

[0025] Furthermore, it also includes a zone heating module, which is installed on the top plate. The zone heating module is electrically connected to the control host, and the control host adjusts the working state of the zone heating module according to the temperature information collected by the infrared temperature sensor.

[0026] Furthermore, the processing decision unit is used to perform character recognition on the writing trajectory or answer image captured by the touch screen, and to automatically match and grade the answers to objective questions.

[0027] Furthermore, the touch screen displays a smart interactive interface, which includes at least:

[0028] The exam status bar displays the remaining exam time and connection status.

[0029] Dynamic question area, used to display encrypted question content within a time limit;

[0030] The handwriting / interactive answer area is used to receive touch input and record the original writing trajectory;

[0034] The answer is matched using OCR recognition technology and a local semantic model;

[0035] After the subjective question images are anonymized and sliced, they are uploaded to the cloud teaching platform via an encrypted link.

[0036] OCR is an abbreviation for optical character recognition.

[0037] The beneficial effects of this invention are as follows:

The image acquisition module 9 is used to acquire facial image information of students, the infrared temperature sensor 6 is used to acquire ambient temperature, and the pressure sensor 7 is used to detect the force state on the desktop.

[0051] A touch screen 5 is embedded in the surface of the desk body 1 and is used for displaying and interacting with exam and teaching content.

[0052] The control host 10 is located inside the desk body 1, and the control host 10 is equipped with a paperless examination unit and a health monitoring unit;

[0053] The paperless examination unit is used to perform dynamic rendering of encrypted test papers, real-time AI grading of objective questions, and identification of abnormal examination behavior.

[0054] The health monitoring unit is used to receive the student's facial image information collected by the image acquisition module 9, perform emotion analysis on the facial image using a convolutional neural network model, and determine the student's fatigue state or poor sitting posture by combining the data from the pressure sensor 7, and send a signal to the control host 10.

[0055] The touch screen 5, the multimodal sensing unit, and the actuator 11 are all electrically connected to the control host 10. The control host 10 controls the actuator 11 according to the signal sent by the health monitoring unit to adjust the desk body 1.

[0056] This invention fundamentally eliminates the printing, distribution, collection, and physical storage of paper-based exam papers, enabling immediate testing and assessment, and significantly improving exam efficiency. Answer data is generated, encrypted, and transmitted directly in digital form, avoiding errors and risks in intermediate stages and ensuring data security and integrity. Simultaneously, it provides a solid data foundation for subsequent big data-based learning analysis and personalized learning path recommendations. This invention not only fully supports a paperless exam process from exam distribution, answering questions, and submission to AI grading and teacher review, but also uses built-in sensors to monitor students' physiological state and emotional changes in real time, achieving synergistic development of teaching assessment and health care.

[0057] Example 2

[0058] Based on Embodiment 1, the present invention provides a smart desk that integrates paperless examination and health monitoring functions. The desk body 1 adopts a modular layered structure, including a top plate 2, a middle layer 3 and a base 13 arranged from top to bottom.

[0059] The touch screen 5 is embedded in the top plate 2, the pressure sensor 7 is located in the middle layer 3, and the control host 10 is located in the base 13.

[0060] like Figure 1 As shown, the image acquisition module 9 is mounted on the top plate 2, and the infrared sensor is also mounted on the top plate 2. In this embodiment, the image acquisition module 9 is a camera.

[0061] Example 3

[0062] Based on Embodiment 1, the present invention provides a smart desk that integrates paperless examination and health monitoring functions, and also includes a communication module 12, which is used to transmit examination data or status data to an external teaching management terminal.

[0063] like Figure 1 As shown, the communication module 12, by realizing real-time, secure and efficient data transmission, not only improves the automation level of examination management, but also provides data support for teaching decisions, making it an indispensable part of modern digital education scenarios.

[0064] Example 4

[0065] Based on Example 1, this invention provides a smart desk integrating paperless examination and health monitoring functions. The paperless examination unit and health monitoring unit configured in the control host 10 operate based on a multimodal data processing architecture, such as... Figure 2 As shown, the architecture includes:

[0066] The data acquisition layer is used to receive raw data from the image acquisition module 9, the infrared temperature sensor 6, and the pressure sensor 7.

[0067] The data preprocessing unit is used to extract features from the facial image data, filter the pressure data, and correct the temperature data.

[0068] The processing and decision-making unit is used to perform paperless examination processing, student attention judgment, and posture recognition, respectively.

[0069] The decision and control unit is used to output reminder instructions or structural adjustment execution instructions based on the processing results.

[0070] The processing and decision-making unit is used to perform character recognition on the writing trajectory or answer image captured by the touch screen 5, and to automatically match and grade the answers to objective questions. It can also encrypt and decrypt the test paper content.

[0071] The health analysis module determines a student's concentration or fatigue state based on facial image features and desktop force characteristics. When an abnormal state is detected, the decision and control unit triggers reminder feedback or structural adjustment.

[0072] Example 5

[0073] Based on Embodiment 1, the present invention provides a smart desk that integrates paperless examination and health monitoring functions. The actuator 11 includes an electric telescopic rod 14, an upper support plate 15, an adjustment panel 4, and a telescopic cylinder. The upper support plate 15 is located below the top plate 2 and the electric telescopic rod 14 and is fixedly connected to both. The control host 10 finely adjusts the height of the upper support plate 15 by controlling the electric telescopic rod 14.

[0074] The telescopic cylinder is located on the lower end face of the adjustment panel 4, and the control host 10 adjusts the angle of the adjustment panel 4 by controlling the telescopic cylinder.

[0075] The top plate 2 includes an adjustment panel 4 and a fixed plate. The fixed plate is located around the adjustment panel 4. The cylinder base 13 of the telescopic cylinder is fixed to the inner wall of the fixed plate (the side closer to where the student sits). The telescopic rod of the telescopic cylinder is located on the lower end face of the adjustment panel 4. When angle adjustment is required, the cylinder is activated, causing the fixed panel (the side away from the student) to move up and down, thus achieving fine-tuning of the angle.

[0076] When the camera, combined with the emotion computing model of the health monitoring unit, identifies that the examinee is experiencing cervical spine pressure overload due to continuous head-down posture, the control host 10 will automatically send a pulse command to the electric telescopic rod 14 to fine-tune the height of the upper support plate 15, thereby achieving dynamic ergonomic correction.

[0077] The health monitoring unit captures micro-expression features through the image acquisition module 9. When the level of focus falls below a set threshold or the pressure sensor 7 detects that the duration of lying down exceeds a preset value, it triggers gentle tactile feedback on the desktop to provide a reminder. Figure 2 As shown.

[0078] Example 6

[0079] Based on Embodiment 1, the present invention provides a smart desk that integrates paperless examination and health monitoring functions, and also includes a partition heating module 8, which is disposed on the top plate 2.

[0087] like Figure 3 As shown, the intelligent interactive interface also includes a homework reminder module 19 and a teaching interaction component 21. The homework reminder module 19 is used to receive homework information sent by the teacher and display the students' completion status. The teaching interaction component 21 is used to provide interactive entry points for raising hands, classroom voting, or environmental control.

[0088] The AI ​​grading process executed by the paperless examination unit includes:

[0089] Extract the image of the handwriting area on the touch screen 5;

[0090] The answer is matched using OCR recognition technology and a local semantic model;

[0091] After the subjective question images are anonymized and sliced, they are uploaded to the cloud teaching platform via an encrypted link.
