And after all courses corresponding to the course numbers are finished, the first main controller automatically deletes the bound course numbers, the teacher information and the student information.
It should be noted that, if the time of the first time counting module deviates from the time of the real world, the time may be manually entered through the first liquid crystal display module at the teacher sign-in end to adjust the time.
S26, the second main controller receives the sign-in success information and an indicator light is on to prompt the student that the sign-in is successful; or voice equipment prompts the students to sign in successfully; and binding the student sign-in information with the student sign-in equipment of the student at the student sign-in end.
In the embodiment of the invention, the indicator light can be used for prompting whether the student successfully signs in, and the voice equipment can be used for prompting whether the student successfully signs in. Specifically, the second main controller receives the sign-in success information, and an indicator light is turned on to prompt the student that the sign-in is successful; or the voice equipment prompts the students to sign in successfully. The second main controller binds the student sign-in information with the student sign-in equipment of the student at the student sign-in end.
S27, if not, the first master controller sends sign-in failure information to the second master controller, and the indicator light flashes to prompt the student that the sign-in fails; or the voice equipment prompts the student that the student is failed to sign in through voice.
In the embodiment of the invention, under the condition that the student sign-in information is not matched with the student information stored in the first storage module, the first main controller sends sign-in failure information to the second main controller, and the indicating lamp flickers to prompt the student that the student fails to sign in; or the voice equipment prompts the student that the student is failed to sign in.
The embodiment of the invention binds the course number, teacher information and student information without entering a teaching service system to download the information, thereby reducing the possibility that the teaching service system is attacked; the time stamp is added to the student sign-in information, so that the credibility of the student sign-in information is improved; judging whether the student is late or not according to the timestamp and the preset class time;
