A Wi-Fi-based sign-in system and method

Abstract

The invention discloses a WiFi-based sign-in system and method. The system includes: a data storage module for storing student account information; a network transmission module for network communication services between modules; a sign-in server for broadcasting It is also used to verify the received sign-in request information; the portable smart terminal is used to sign in according to the received UDP package information. If the information in the UDP package is correct, the sending includes: The sign-in request, student information, and mobile phone hardware information sign-in request information is sent to the sign-in server; it is also used to receive the sign-in success information sent by the sign-in server; the statistics module is used to count the student sign-in situation according to the sign-in information; the display module is used to display the sign-in The information is for students to confirm. The invention aims at the time-consuming and labor-intensive problems of traditional classroom sign-in or verbal sign-in, so that each sign-in can be completed within a few minutes, has high accuracy, is convenient to use, and saves a lot of time.

Description

technical field [0001] The invention relates to information technology, in particular to a WiFi-based Android sign-in system. Background technique [0002] Roll call is an important part of attendance check in colleges and universities. At present, classroom sign-in is mainly based on verbal roll call. This method is straightforward and simple, but when there are a large number of students, it often takes up more classroom time, and it is easy for students to respond on behalf of students. [0003] In recent years, many colleges and universities have also tried rich roll call or sign-in solutions, such as face detection technology and fingerprint detection technology. This kind of scheme can effectively prevent the replacement of roll call, but the order of roll call is not easy to control, and the accuracy is easily affected by the change of students' appearance, and private information such as fingerprints is also easy to leak and unsafe; another category is mobile phone ...

AI Technical Summary

Problems solved by technology

This type of scheme can effectively prevent the replacement of roll call, but the order of roll call is not easy to control, and the accuracy is easily affected by the change of students' appearance, and private information such as fingerprints is also easy to leak and unsafe; another type such as mobile phone Bluetooth, QR code scanning, etc.

The implementation cost of Bluetooth check-in is low and simple, but the mobile phone is required to support the Bluetooth function, which is not universal and limited by the distance, so it cannot avoid the situation that students carry other Bluetooth devices instead of check-in; and the QR code scanning takes too long and is difficult high equipment requirements
