Wifi (wireless fidelity)-based classroom automatic attendance method, system and server

Abstract

The invention provides a wifi-based classroom automatic attendance method. The wifi-based classroom automatic attendance method comprises the following steps: presetting a wifi network and pre-storing user information of a first electronic device and a plurality of preset second electronic devices in a server; enabling the server to obtain information of the plurality of the preset second electronic devices connected with the wifi network after receiving a request command sent by the first electronic device; counting the number of the second electronic devices connected with the wifi network to get a first counting number; counting the number of students in a classroom by image recognition to get a second counting number; and enabling the server to record the attendance status of the students according to the first statistical number if the second statistical number is equivalent to the first statistical number. The classroom automatic attendance method provided by the invention is simple to operate, and can reduce the on-class roll call time and the after-class attendance recording time of teachers and improve the authenticity in attendance recording. Simultaneously, the invention provides a classroom automatic attendance system and the server.

Description

technical field [0001] The present invention relates to the field of education management, in particular to a based on wifi Classroom automatic sign-in method, system and server. Background technique [0002] At present, the methods used in campus classroom attendance include manual roll call according to the roster, attendance machine punch card roll call, and attendance machine fingerprint attendance. Among these methods, the manual roll call of the roster is not only inefficient in roll call and statistics, but also takes up a lot of valuable classroom time. When checking attendance with other attendance machines, students need to go to the machine at the attendance point to complete the attendance in a short period of time before and between classes. Queues and congestion frequently occur, causing chaos on the spot, delaying class time, and affecting efficiency. [0003] The Chinese patent of application number 201210161007.2 " a kind of operation method of bluetooth...

AI Technical Summary

Problems solved by technology

This method needs to be increased so that the computers used for the roll call must be installed with the corresponding Bluetooth search enhancer, and the time when the students actually sign in cannot be clearly defined when the roll call is performed.

[0004] There are still some problems with the above methods, that is, if a student signs in instead of other students, these systems or methods cannot be identified or discovered in time, resulting in the attendance assessment not really functioning
