Problems solved by technology

Overall, the attendance rate of juniors and seniors is generally lower
[0008] 3) Difficulty in classroom interaction
In university classrooms, the seats are not fixed, and at the same time, a teacher usually leads a class of students and there is usually no intersection. In this case, it is difficult for the teacher to match the names of the students with the students one by one, and the classroom interaction can only be by random point-to-point
[0009] 4) Time-consuming roll call and low efficiency
Traditionally, the system of roll call is adopted to increase the rate of student attendance. However, the teacher cannot roll the roll in every class, but can only do spot checks. Due to the limited class time and the large number of students, the class time is greatly delayed, and the frequent roll call by the teacher will cause students to rebel. Psychology, leaving students with the illusion that the teacher's teaching ability and classroom management level are not high
[0010] 5) Controversy over usual grades
Since students' attendance at class usually accounts for the main part of their usual grades, and their grades will be zero if they fail to come to class three times, it is inevitable that some students will think opportunistically, make up reasons for their absence, and even argue with the teacher
[0011] 6) Counselors have a heavy workload, and a comprehensive understanding is time-consuming and labor-intensive
There may be hundreds or even thousands of students in a grade, and the counselors need to manage a huge number of students. Strictly speaking, they need to check the class situation, but after all, their energy is limited, and it is impossible to pay attention to every student in each class. students
[0012] 7) It is difficult to provide psychological counseling to students in advance
[0017] The low attendance rate of students in existing colleges and universities and students answering and signing on behalf of students
The campus card application can no longer meet the current network application development
At the same time, the data security of the smart sign-in APP of the existing electronic campus card is low
Poor management of data access permissions
[0018] The obtained sign-in data has a low dimension, and can only reflect whether to attend the class, but cannot reflect "sitting information", "effective classroom seat block", etc., ignoring the effective use of big data technology for rich first-hand classroom information

Embodiment 1

[0122] The encryption module 7 encryption method that the embodiment of the present invention provides comprises:

[0123] (1) Receive the data to be encrypted, the initial key value, and the mask value through the encryption program, and after the data to be encrypted is XORed with the masked value, then XORed with the initial key value to generate XORed mask data , this process takes time t.

[0124] (2) Perform row conversion processing on the XOR mask data to generate row conversion data, and perform split processing on the second converted data to generate first split data, second split data, and third split data Data and the fourth split data, this process takes time t.

[0125] (3) Randomly select the first split data for re-split processing to generate four groups of first re-split data, randomly perform byte replacement processing on the first re-split data of the four groups at the same time, generate four A group of byte substitute data is reassembled for four gro...

Embodiment 2

[0136] The rights management module 8 management methods provided by the present invention include:

[0137] 1) Obtain the authorization information from the received authorization SQL statement through the management program.

[0138] 2) When the authorization information includes the column identifier, add the authorization record generated according to the authorization information to the column authorization data table of the metadata database; when the authorization information does not include the column identifier, add the authorization record according to the The permission record generated by the authorization information is added to the table permission data table of the metadata database.

[0139] 3) When receiving the access SQL statement, perform table-level authority verification on the access SQL statement according to the authority record in the table authority data table, and when the table-level authority verification fails, according to the column authority da...

Embodiment 3

[0141] The management method provided by the embodiment of the present invention also includes:

[0142] Obtain revocation information from the received permission revocation SQL statement.

[0143] When the recycling information includes a column identifier, search for a permission record matching the recycling information in the column permission data table; when the recycling information does not include a column identifier, search in the table permission data table Find a permission record that matches the reclaim information.

[0144] Delete the found permission records.

Abstract

The invention belongs to the technical field of intelligent sign-in, and discloses a sign-in APP coupled with an electronic campus card and a construction method of a student classroom multi-dimensional information base, and the method comprises the steps that the primary sign-in is carried out through an electronic two-dimensional code generated in the APP; the page of the APP jumps to a countdown page, and students can scan the two-dimensional code on the table on the selected seat to sign in for the second time after timing is finished; the educational administration system records each sign-in condition of the students; a teacher inquires the sign-in of a class and the distribution condition of class seats in an educational administration system. According to the invention, a basic classroom sign-in function can be realized, and more real first-hand multi-dimensional information records can be provided for understanding the interpersonal relationship of students, so that parents and counselors can understand the psychological health of students in time, and communication or intervention guidance can be provided in time; moreover, the educational administration department can refer to and evaluate the teaching effects of class schools and teachers through the relative distribution of classroom seats.

Description

technical field [0001] The invention belongs to the technical field of intelligent sign-in, and in particular relates to a sign-in APP coupled with an electronic campus card and a construction method of a student classroom information database. Background technique [0002] Take out your mobile phone, open Alipay and scan it, and scan the school’s exclusive QR code to receive an electronic campus card. A set of actions that only takes more than ten seconds to complete is changing the campus life of students. [0003] From physical campus cards to electronic campus cards, as we all know, one of the main contents of college informatization construction in the past ten years is the construction of campus cards, and its goal is to "open up all services with one card". Taking Hangzhou Normal University as an example, the electronic campus card promoted by a normal university is an attempt to "load" the existing physical campus card into mobile phone Alipay, that is, to realize th...
