Real-time attendance check system based on two-dimensional codes and location service

Abstract

The invention discloses a real-time attendance check system based on two-dimensional codes and location service. The real-time attendance check system includes a user and right management module, an attendance check management module and a leave application management module; the user and right management module involves user application and registration, user login, user rights, user logout and password modification; the attendance check management module involves enabling attendance check, generating attendance check records, modifying attendance check records, and viewing attendance check records according to categories; and the leave application management module has four functions, namely uploading leave applications, modifying leave applications, previewing leave applications, and examining and approving leave applications. With the real-time attendance check system based on two-dimensional codes and location service of the present invention adopted, high-efficiency, automated and batched attendance check can be achieved, and high-efficiency, high-accuracy, and low-cost attendance check can be realized.

Description

technical field [0001] The invention belongs to the technical field of management systems, and relates to a real-time attendance system based on two-dimensional codes and location services. Background technique [0002] The current classroom attendance is almost manual roll call, the effect of random roll call is mediocre, the comprehensive roll call takes a lot of time, and there are many inconveniences in statistics. Although there are fingerprint machines, face recognition devices, and face recognition deployment control systems, the hardware and algorithm efficiency The requirements are high, and the effect of parallel batch roll call is poor. With the wide application of new technologies such as mobile Internet, QR code technology and LBSLocation based services, the interaction and management of various information has become more intelligent and efficient. Moreover, almost every college student today has a smartphone. [0003] With the widespread application of new t...

AI Technical Summary

Problems solved by technology

[0004] (1) There are a large number of students, and they cannot be ordered all at once, otherwise it will take a long time in class

Taking a classroom with 200 students as an example, the efficiency of roll call is calculated according to 3s / person, and it takes 600s, about 10 minutes, for the whole roll call, accounting for about 10% of the effective class time, which is inefficient and seriously affects the progress of the class

[0005] (2) Difficulty in multiple roll call

Still limited by the effective teaching time, it is impossible to call the full name in every class, and skipping classes with a fluke mentality often happens

[0007] (4) The efficiency of the leave approval process is low, and the management of students' paper leave slips is inconvenient and easy to lose, which is not conducive to archiving

[0008] (5) It is inconvenient to count attendance results

When calculating attendance results, relying on purely manual statistics is time-consuming and error-prone, and cannot effectively guarantee the fairness of results

[0009] (6) Unable to do linkage analysis and timely supervision and reminder

A student takes multiple courses, but each teacher can only manage the attendance status of one course, and cannot collect all the attendance data for linkage analysis, and cannot realize the overall monitoring and timely vigilance of students with high absenteeism rates, and there is a management blind spot

Counselors and academic affairs departments are also unable to obtain the attendance status of each course in a timely and accurate manner
