Description

Technical Field

[0001] This invention relates to an intelligent classroom anti-truancy device and system, which prevents students from skipping class midway through the lesson. It belongs to the field of intelligent classroom technology, and specifically relates to an intelligent classroom anti-truancy device and system that uses multiple facial recognitions to prevent students from skipping class midway through the lesson. Background Technology

[0002] With the explosive growth of information technology, smart classrooms, as a new form of education and a modern teaching method, have brought new opportunities to the education industry. Before using a smart classroom, it's necessary to confirm student attendance. Currently, this mainly involves students wearing student cards with NFC chips, swiping their cards upon entering the classroom using a sensor. The system records student attendance, but this cannot prevent students from having others swipe their cards for them. Furthermore, since the card is only swiped once before class and not during the lesson, it's impossible to know if students are skipping class, seriously affecting their learning progress.

[0003] Publication number CN206621057U discloses an information management device for taking attendance during class, including table legs and a table body. The upper end of the table body is provided with a groove, and a tabletop is provided in the groove. The front left and right sides of the tabletop are hinged to the table body by pins. The rear left and right sides of the tabletop are provided with slide rail seats, and the outer surface of the slide rail seats is provided with a sliding groove. The table body is provided with locking elements on the left and right sides of the groove, and the locking elements include connecting rods. However, the above device only uses an iris recognition device to identify students' eyes before class to determine whether students are attending class, but it does not monitor whether students are attending class during class, and cannot prevent students from skipping class. Summary of the Invention

[0004] To improve the above situation, the present invention provides an intelligent classroom anti-truancy device and system that uses multiple facial recognitions to prevent students from skipping class.

[0005] The intelligent classroom anti-truancy device and system of this invention are implemented as follows: The intelligent classroom anti-truancy device of this invention consists of a student desk, a computer placement slot, a miniature pressure sensor, a fixing sleeve, a desktop computer, a fixing hinge, a camera, and a computer integrated together. The students' desks have slots for placing computers. The fixed pivot is positioned on one side of the computer placement slot. The miniature pressure sensor is located on the other side of the computer mounting slot. Preferably, the miniature pressure sensor is positioned in the center of the other side of the computer placement slot. The fixing sleeves are placed at both ends of the fixing rotating shaft. The desktop computer is connected to the fixed pivot via the fixed sleeve, and the desktop computer can be rotatably placed in the computer placement slot via the fixed pivot. The desktop computer has a camera embedded in the top center. Preferably, the computer placement slot is the same size as the desktop computer. The student desk has an integrated circuit installed at the bottom, which is connected to the desktop computer. Furthermore, the student desk has a reserved slot, which is located in the middle of the other side of the computer placement slot; Preferably, the reserved slot has an arc-shaped structure; Furthermore, the computer placement slot is equipped with a protective pad. Preferably, the protective pad has anti-slip texture; Preferably, the protective pad and the computer placement slot are the same size.

[0006] The present invention, an intelligent classroom anti-truancy system, includes a student information management system, a teacher's computer, and an anti-truancy device, characterized in that: A communication connection is established between the teacher's computer and the anti-truancy device. A communication connection is established between the teacher's computer and the student information management system. The student information management system is used to store students' identity information. Preferably, the student's identity information includes facial information, name, student ID, seat number, and selected courses, etc. The teacher's terminal, installed on the teacher's end, compares the student facial information collected by the anti-truancy device with the student information management system, and marks students who skip class. Preferably, teachers can determine a standard for the number of times a student's facial recognition match fails, based on whether the student is making or receiving phone calls outside or is unable to complete the facial recognition process due to looking down. If a student's number of failed facial recognition matches reaches the standard number, it is considered truancy; if the number of failed facial recognition matches does not reach the standard number, it is considered normal attendance. An anti-truancy device is installed on the student's end. The camera in the device repeatedly captures the student's face during class and transmits the captured facial information to the desktop computer's data processor. The desktop computer's data processor combines the student's facial information and seat number into a data set and sends it to the teacher's computer. Preferably, the multiple data collections can be performed every five minutes by collecting the student's face. The present invention relates to a smart classroom method for preventing truancy, characterized by using a smart classroom anti-truancy system to manage student attendance and includes the following steps: (1) Before class, the teacher inputs the classroom information into the teacher's computer, and the teacher's computer transmits the classroom information to the student information management system. (2) The student information management system retrieves the student information for the course and transmits it to the teacher's computer; (3) When students are in class, if the pressure value collected by the miniature pressure sensor in the anti-truancy device is less than the preset initial value, it means that the desktop computer will open from the computer placement slot, the desktop computer's camera will turn on, and the facial information of the student who has arrived at the seat will be collected. (4) The facial information is transmitted to the data processor of the desktop computer. The data processor of the desktop computer forms a data group of the student's facial information and the corresponding seat number and sends it to the teacher's computer. (5) The teacher's computer compares the student's facial information with the student's facial information retrieved from the student information management system and confirms whether the seat number is consistent to determine whether it is the student. If it is the student, the facial information will be collected again for comparison after a preset time interval. If it is not the student, the student's facial recognition matching fails and is counted once. If the number of times the count exceeds the preset number, it is considered that the student skipped class and the student's identity information is registered. Beneficial effects

[0007] First, by conducting multiple facial recognition checks on students during class, it is possible to prevent students from skipping class.

[0008] Second, facial recognition is used to confirm whether students are in class, enabling roll call with high accuracy.

[0009] Third, it has a simple structure and is convenient and practical. Attached Figure Description

The present invention, an intelligent classroom anti-truancy system, includes a student information management system, a teacher's computer, and an anti-truancy device, characterized in that: A communication connection is established between the teacher's computer and the anti-truancy device. A communication connection is established between the teacher's computer and the student information management system. The student information management system is used to store students' identity information. Preferably, the student's identity information includes facial information, name, student ID, seat number, and selected courses, etc. The teacher's terminal, installed on the teacher's end, compares the student facial information collected by the anti-truancy device with the student information management system, and marks students who skip class. Preferably, teachers can determine a standard for the number of times a student's facial recognition match fails, based on whether the student is making or receiving phone calls outside or is unable to complete the facial recognition process due to looking down. If a student's number of failed facial recognition matches reaches the standard number, it is considered truancy; if the number of failed facial recognition matches does not reach the standard number, it is considered normal attendance. An anti-truancy device is installed on the student's end. The camera (7) in the anti-truancy device collects the student's face multiple times during class and transmits the collected student's face information to the data processor of the desktop computer (5).
