In the process of students' learning, teachers can send classroom information to the communication module through terminals such as mobile phones or tablets every time they take a class, and students can send student information to the card reader of the acquisition module through the student card. The student data is sent to the control module, and then the control module sends the student data to the cloud storage subsystem for storage through the communication module. When the collection time interval is greater than the time threshold, the module adds a dropout label to the student data, so as to monitor whether the student is in school in time, which is convenient for monitoring and educating students who drop out.

Before collecting the grade information, the students turn the screw head 4 clockwise or counterclockwise, the screw head 4 drives the gear 5 to rotate clockwise or counterclockwise, and the gear 5 moves up or down along the rack 6 on the inner wall of the sliding hole 7 move, so as to drive the lock tongue 3 into or out of the slot, no matter which direction the screw head 4 is twisted, as long as it can drive the gear 5 to move, so that the students can use the table belly freely, and the timing module sends the acquisition signal to the control module After that, the control module controls the retractable piece to be inserted into the jack of the lock tongue 3, and limits the position of the lock tongue 3 to prevent students from using the table belly and the cover plate 2 arbitrarily. It allows students to continue to use the hole, thereby forcing students to input grade information, ensuring the timeliness of data collection, and preventing teachers from missing data due to a large number of input.

When students are regularly asked to take various quizzes and get their results, such as classroom quizzes, mid-term exams and final exams, that is, the timing module sends a collection signal to the control module, and the control module controls the cylinder of the locking mechanism to start, so that the cylinder's The piston rod is inserted into the jack of the lock tongue 3, and the sealing plate 2 is locked. Students are not allowed to use the sealing plate 2 by using the lock tongue 3. After locking the sealing plate 2, the digital keys of the acquisition module are used for each student to input the score information. The module does not collect the student's grade information, and keeps the locking mechanism in the locked state. When the control module obtains the student's grade information from the acquisition module, the control module controls the cylinder of the locking mechanism to retract the piston rod to open the sealing plate 2, so that the students can open the sealing plate. Board 2 uses the table belly to place items, collects a large amount of student data during the student's learning process, and links the use of the table belly to force students to input grade information, reduce the workload of inputting grades through teachers, and send the students at the same time as they know the grades. It is stored in the cloud storage subsystem to avoid the lag in data collection caused by teachers entering students' grades in the later stage.

During the course of the students listening to the class, the sitting posture detection module collects the students' listening postures and sends them to the control module. The infrared camera unit of the sitting posture detection module captures the students' back neck images as the teaching postures, and the control module compares the listening postures with the pre-stored classroom postures. Matching, when the listening posture matches the classroom posture, compare the tilt and vertical angle of the image of the back of the neck. When the angle is greater than the angle threshold, the matching fails, and the matching failure means that the student did not listen to the class carefully, and the listening posture is regarded as the student. It can collect the classroom performance data of each student in time, without the need for teachers to observe the daily performance of each student during teaching, and avoid student data omission.

The student data of each student is collected by the collection subsystem on desk 1. Since desk 1 is used in different learning stages of students, the collection subsystem on desk 1 will track and collect student data. , to collect the data of students in different learning stages, the data is more complete.
