Roll call device and method based on wireless network

Abstract

The invention provides a roll call device and method based on a wireless network. The method comprises the steps that S1, a roll call terminal enters a roll call applet to create a sign-in webpage, generates a one-time jump code for entering the webpage, and transmits the one-time jump code to the roll call device; S2, the roll call device receives and displays the jump code; S3, a sign-in terminal scans the jump code to enter the roll-call applet, after the roll-call applet detects that the jump path is used, the jump path is closed, and the jump code is invalid; S4, the roll-call applet obtains model information of the sign-in terminal, automatically registers and logs in an account, obtains position information authority and generates a position map; S5, after the sign-in terminal completes sign-in and quits the roll-call applet, the roll-call applet automatically cancels the account; and S6, the roll-call applet records and compares the sign-in information at the background, and abnormal sign-in terminal information is popped up at the roll-call terminal. According to the invention, roll call can be carried out quickly and efficiently, the class time is not affected, and questions answered on behalf can be avoided.

Description

technical field [0001] The invention relates to the technical field of wireless network roll call, in particular to a wireless network-based roll call device and method. Background technique [0002] The characteristics of the WeChat roll call applet: various functions can be developed, which are more comprehensive than the functions realized by traditional web pages; the roll call applet is loaded faster, and the basic elements of the roll call applet do not need to be loaded; the roll call applet is uploaded because the code It is on the WeChat server, so the security is relatively high; the roll call applet has no entry in WeChat, and the roll call applet needs to be scanned with a mobile phone camera. [0003] Nowadays, there are a large number of college students. Sometimes there are more than one hundred students in a class.

[0003] Nowadays, there are a large number of college students. Sometimes there are more than one hundred students in a class. It has become a difficult problem for teachers in various universities to manage students in class. Due to the poor self-control of students, teachers and schools need to supervise in many aspects , so teachers need to roll their names in the classroom. Now most of the university teachers roll their rolls on the spot in the classroom, which not only wastes a lot of classroom time, but also replaces the answers. It is not uncommon in university classrooms; therefore, there is a need for a roll call device that can quickly and efficiently roll rolls without affecting the class time, and at the same time avoid the questions answered by proxy
