[0027] An alarm 10 and a speaker 9 are respectively provided on the left and right sides of the camera 5, a suction cup base 4 is provided at the lower end of the roll-call terminal 1, a display screen 2 is provided at the front end of the roll-call terminal 1, a handle 14 is provided on the rear side of the roll-call terminal 1, and a data connection device electrically connected to the background teaching host is provided at the lower end of the suction cup base 4. The front end of the display screen 2 faces the nodes 13 distributed in a matrix. The nodes 13 are evenly spaced on the desks in the classroom, and the nodes 13 are connected to the roll-call terminal 1 via wireless data.

[0028] The roll-call terminal 1 is provided with a roll-call system, which is composed of a data processing module, a correction module and a roll-call module. The correction module is composed of a camera module for face recognition and a thermal imaging module for number recognition. The roll-call module includes a selection module and a sound module. The data processing module is composed of a data receiving module and a data comparison module.

[0029] The roll call system is connected to the background education host through the data receiving module and generates a teaching list with photo information. The teaching list is stored in the data comparison module for comparison. The response of the alarm 10 is controlled according to the comparison result.

[0030] The selection module includes two modes: full roll call and random roll call. The roll call list is selected and screened manually, and the roll call list is output through the speaker 9 and received by the response module through the node device 13.

[0031] In the correction module, the camera 5 adjusts the angle according to the position responded by the node device 13 and takes real-time pictures. The recognition pictures taken by the camera 5 are compared with the data comparison module. The correction module identifies the number of students in the teaching through the thermal imaging module and intelligently selects the roll call mode according to the number of students in the teaching.

[0032] Working principle: The roll call process includes the following steps:

[0033] Step 1: Data reception. Connect to the background host through the data receiving device, and transmit the student list data with photos to the roll call system to obtain the standard number of people R.

[0034] Step 2: System determination. Measure the actual number of people N in the classroom through the thermal imaging device. If N = R, manually select full roll call or random roll call through the selection module. If N < R, it means that there is a problem of someone being absent, and the system automatically selects full roll call for investigation.

[0035] Step 3: Roll call response. The roll call is broadcast through the speaker, and the response is made through the response device of the node device 13 on the seat. The camera 5 adjusts the angle of the camera 5 through the servo motor 11 according to the position of the responded node device 13 and collects image data.

[0036] Step 4: Data feedback. Compare the collected data with the standard list through the data comparison module for image comparison. If they match, proceed to the next roll call. If they do not match, mark and give an alarm prompt.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
