Problems solved by technology

[0004] This solution can verify the identity of students in class by means of face recognition verification, realize the integration of person, place and time, and help teachers complete attendance check-in; however, because face recognition technology mainly recognizes students through facial features Identity, to match and identify the student’s face information with the photo information in the collection library, requires a large amount of money to purchase face recognition equipment; not only that, whether the shooting environment is well lit and the camera shooting angle may become a mistake in the judgment of the face recognition module The reason; the use of break time is not enough for all students to complete face recognition attendance, there is a problem of inconvenient use, which affects user satisfaction

Embodiment 1

[0042] Such as figure 1 As shown, a reverse sign-in system for students includes a student mobile phone terminal, a teacher mobile terminal, and a server; wherein, the server includes a request forwarding module, a database, an analysis module, a processing module, and an output module; both the student mobile phone terminal and the teacher mobile phone terminal use Huawei P30 Pro, the server is Dell EMC PowerEdge R240 rack server.

[0043] The teacher's mobile phone terminal is used for the teacher to initiate a classroom roll call request;

[0044] The student mobile phone terminal is used for students to passively sign in to the classroom roll call request initiated by the teacher's mobile phone terminal, and generate passive sign-in information; the passive sign-in information includes the student's passive sign-in time information, passive sign-in location information and student personal information; and in the passive sign-in Perform reverse check-in before, generate r...

Embodiment 2

[0054] Compared with Embodiment 1, the only difference is that in this embodiment, the student’s mobile phone terminal is also used to collect the current sound information of the student, and the sound preprocessing module is used to perform noise reduction processing on the current sound information; specifically, this embodiment The noise reduction process uses Cool Edit audio processing software, which has a mature audio noise reduction function. This technology is an existing technology and will not be repeated here; Based on receiving and processing the current voice information according to the historical voice information, if the current voice information is the same as the historical voice information, it is judged that the current sign-in student is the person; otherwise, if the current voice information is different from the historical voice information, an alarm message is generated and the Alarm information and student personal information are sent to the teacher's...

Embodiment 3

[0057] Compared with Embodiment 1, the only difference is that the student's mobile phone is also used to collect the current face image information of the students through the built-in camera, and integrate the current face image information of each student according to the student's personal information to generate a total face image information. The face image information is stored in the database; the database is also used to pre-store the historical face image information of the students; the processing module is also used to receive and process the current face image information according to the historical face image information, if the current face image information is different from the historical image information If the information is the same, it is judged that the current sign-in student is himself; on the contrary, if the current face image information is different from the historical face image information, it is judged whether there are two identical current face ...

Abstract

The invention relates to the technical field of information, and particularly relates to a student reverse sign-in system. The system comprises a student mobile phone terminal, a teacher mobile phoneterminal and a server; the server comprises a request forwarding module, a database, an analysis module, a processing module and an output module, wherein the request forwarding module is used for receiving a classroom roll call request sent by the teacher mobile phone terminal and forwarding the classroom roll call request to the student mobile phone terminal; the database is used for receiving and storing the passive sign-in information, the reverse sign-in information and the student personal information sent by the student mobile phone terminal; the analysis module is used for presetting sampling people number information, sequentially receiving passive sign-in time information and passive sign-in position information with the same number as the sampling people number information according to a time sequence, calculating the mode of the passive sign-in time information and the passive sign-in position information, and generating time reference information and position reference information. By adopting the scheme, the user satisfaction can be improved.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a reverse sign-in system for students. Background technique [0002] With the advancement of the reform of our country's colleges and universities, the credit system has become the most common teaching method in our country's colleges and universities. Under the credit system education model, students do not have to strictly follow the class system of the college for classroom learning, but choose subjects freely under the school teaching framework according to their own interests and actual conditions, as long as they complete the minimum credits in the student training program before graduation You can graduate successfully. However, this teaching method has brought certain difficulties to the attendance work in colleges and universities. Since the students in the same class may come from multiple colleges, multiple majors or multiple classes, the teachers are not familia...
