The threshold value may be adjusted appropriately according to different ages.

When the student stands, the microprocessor 21 controls the first ultraviolet LED lamp 412 to emit positioning light to one of the positioning switches of the positioning switch array 42 according to the standing signal. And sends the standing signal and the electronic identity information of the student corresponding to the school badge to the big data server 3.

The microprocessor 21 is also connected with a voice acquisition module 28, and the microprocessor 21 controls the voice acquisition module 28 to acquire standing speech records according to the standing signals and sends the standing speech records to the big data server 3;

the microprocessor 21 controls the voice acquisition module 28 to acquire standing speech recording according to the standing signal, and the standing speech recording is sent to the big data server 3 for storage through the GSM module 211;

the positioning switch array 42 is an ultraviolet photosensitive diode array, the video snapshot system 43 is provided with a first single chip microcomputer 431, and the first single chip microcomputer 431 is connected with the ultraviolet photosensitive diode array to lock the position of a student; first singlechip 431 is connected with first camera 432, and first camera 432 passes through slewing mechanism 433 and installs on the roof in classroom the place ahead, and first singlechip 431 control slewing mechanism 433 rotates and makes first camera 432 turn to student's position, and first singlechip 431 connects big data server 3 through first WIFI module 434, router 435, and first singlechip 431 obtains student's the speech video of standing through first camera 432 and sends for big data server 3.

As shown in fig. 3, the positioning switch array 42 is provided with 6 rows and 9 columns of positioning switches, i.e., 6 rows and 9 columns of ultraviolet photodiodes, pins P1.0-P1.5 of the microprocessor 21 are connected with row scanning lines, the row scanning lines are sequentially connected with the cathodes of the positioning switches of the rows, pins P2.0-P2.7 and P1.6 of the microprocessor 21 are connected with column scanning lines, the column scanning lines are sequentially connected with the anodes of the positioning switches of the columns, the microprocessor 21 sequentially applies positive voltages to the scanning lines of the rows and sequentially detects voltage signals through the scanning lines of the columns, and if the positioning switch of a certain row is triggered and conducted by positioning light emitted by a certain first ultraviolet LED lamp 412, the microprocessor 21 identifies the position of the positioning switch and the corresponding seat.

Since the positioning switch array 42 corresponds to the student's seat, the first single chip microcomputer 431 can lock the student's seat according to the signal of the first ultraviolet LED lamp 412; the first single chip microcomputer 431 controls the rotating mechanism 433 to rotate so that the first camera 432 can turn to the position of the student, and standing speaking videos of the student are captured. The teacher can download related videos and recorded data in the big data server at the end of the period to evaluate the learning performance of the students in the period.

The rotating mechanism 433 comprises a first motor 4331, the first motor 4331 is connected with a gear reduction mechanism 4332, an output shaft of the gear reduction mechanism 4332 is fixedly connected with a first camera 432, an output shaft of the gear reduction mechanism 4332 is further connected with a positioning contact rod 4333, an arc-shaped microswitch array 4334 is arranged corresponding to the positioning contact rod 4333, a microswitch of the microswitch array 4334 corresponds to a positioning switch of the positioning switch array 42 in position, the positioning contact rod 4333 corresponds to a microswitch of the microswitch array 4334 in rotation, the microswitch array 4334 and the first motor 4331 are connected with a first single chip microcomputer 431, the first single chip microcomputer 431 controls the first motor 4331 to rotate according to signals of the positioning switch array 42 and the microswitch array 4334, and the camera 432 is controlled to turn to the position of the student to obtain standing speaking videos of the student.

The first motor 4331 and the gear reduction mechanism 4332 are fixed on the roof in front of a classroom, a microswitch of the microswitch array 4334 corresponds to the position of a positioning switch of the positioning switch array 42, the first single chip microcomputer 431 controls the first motor 4331 to rotate, the first motor 4331 rotates to drive an output shaft of the gear reduction mechanism 4332 to rotate, the output shaft of the gear reduction mechanism 4332 is driven to rotate to drive the camera 432 to rotate, the positioning touch rod 4333 rotates correspondingly, when the positioning touch rod 4333 touches the microswitch corresponding to a student seat, the first single chip microcomputer 431 controls the first motor 4331 to stop rotating, and at the moment, the camera 432 turns to the position of the student to acquire standing speaking videos of the student.

The student standing recognition device 41 may also be a pressure sensor disposed in a student seat, and when the pressure sensor detects a pressure signal, it indicates that the student is sitting, and when the pressure sensor does not detect the pressure signal, it indicates that the student is standing, and controls the first ultraviolet LED lamp 412 to emit positioning light. The pressure sensor is wirelessly connected with the microprocessor 21, but students need to sit in a check number and cannot sit in disorder.
