1 Overview
The new college entrance examination reform has broken the previous high school Chinese and science subjects, which has brought about a large-scale selection of classes and classes in high schools. A series of management failures followed. It used to be a fixed class and a fixed timetable. Now it is for each student. A timetable, students go to classes on the move, how to grasp the students’ learning dynamics, grasp the students’ attendance in class, the status of the trajectory of activities in the school, etc., is one of the pain points in the promotion of the class system.
Existing shift attendance mostly adopts the scheme of short-distance swiping card based on electronic shift badge. Short-distance swiping card attendance can easily cause students to gather in a short time, change the behavior of students in and out of the classroom, and it is difficult to implement and persist on a large scale.
2. Technical solution for shift attendance
2.1. Long-distance shift attendance scheme based on electronic class card
The automatic attendance diagram of the electronic class card combined with the RFID reading unit is as follows:
The electronic class card is embedded with an RFID reading unit. Students carrying RFID cards or bracelets will be automatically read when the area is covered by the electronic class card RFID reading unit during class hours, and the attendance information will be automatically recorded.
Zhuojin Communication can provide electronic class card equipment with built-in RFID reading module, and can also provide RFID reading module to dock with any electronic class card equipment to realize long-distance shift attendance. The principle of the docking technology is as follows:
The existing conventional electronic class cards are composed as follows:
The docking transformation of Zhuojin Communication RFID electronic class card is as follows:
On-the-job attendance based on electronic class cards is only an upgrade of attendance experience, which can improve attendance efficiency without changing student behavior, but there is no guarantee that students are sure to enter the classroom.
2.2. Shift attendance scheme based on RFID area sensing equipment
The shift attendance scheme based on RFID area sensing equipment can realize the attendance attendance shift attendance by analyzing the movement trajectory of the students.
The principle of RFID area recognition to achieve shift attendance is as follows:
The red part in the picture is the signal coverage of the RFID identification point
When students pass the door of the classroom, they are read by the RFID calibration reader deployed at the door.
The system backstage judges whether the student enters the classroom through the trajectory of the student area. If the area where the student leaves last is the door of the classroom, it can be judged that the student entered the classroom.
If the area where the student leaves last is at both ends of the stairs or walkway, it is judged that the student is not in the classroom.
The RFID area identification method can also be combined with the electronic class card.
This method is a more cost-effective way of attendance.
2.3. RFID real-time attendance
The schematic diagram of RFID real-time attendance mode is as follows:
Deploy RFID reading equipment on the top of the classroom to fully cover the classroom area. During class hours, the attendance roll-call mode is automatically activated to read all RFID cards or watch information in the coverage area to achieve real-time attendance. Through software settings, you can Real-time roll call at any time during class time.
