Narrowband Internet of Things based student attendance and positioning system

Abstract

The invention relates to the field of student attendance and safety positioning, and provides a narrowband Internet of Things based student attendance and positioning system. The system includes a student card, a gateway radio frequency transmitting device, an intelligent device receiving terminal, and a main server. The student card includes a radio frequency receiving module, an MCU microprocessor, a GSM / GPRS communication module, a positioning module, a battery module, and an SIM card. The main server includes a data receiving platform, a data storage platform, a data analysis platform, a data control platform, a front-end instant query platform, and a front-end history query platform. The intelligent device receiving terminal downloads a main server APP so as to check attendance and positioning data of the student card associated with the main server at any time. Through the combination of attendance and positioning, the narrowband Internet of Things based student attendance and positioning system can improve the school attendance efficiency and prevent potential safety hazards of students. Parents can instantly know the position of the student and recent activities and rules of the student through the intelligent device receiving terminal so as to further improve life rules of the student.

Description

technical field [0001] The invention relates to the field of student attendance and safety positioning, in particular to a student attendance and positioning system based on narrowband Internet of Things. Background technique [0002] Passive RFID access control system or fingerprint access control requires students to swipe their cards or press fingerprints on one or more fixed devices one by one. Active RFID also requires a short distance between the student card and the receiver or a door frame receiver, if When a large number of students pass through, it will cause crowded queues and waste unnecessary time. [0003] The traditional student electronic attendance system installs electronic attendance equipment at the school gate. Among them, the passive RFID access control system or fingerprint access control requires students to swipe their cards or press their fingerprints on one or more fixed devices one by one. When students pass the school gate, they swipe their cards...

AI Technical Summary

Problems solved by technology

This method of electronic attendance and SMS notification still has major defects in practice: first, students must swipe their cards or press their fingerprints one by one, which may easily cause congestion and retention of students at the school gate; second, the initiative to swipe their cards is in the hands of students Students may forget to swipe their cards when they pass the school gate, or they may return after swiping their cards, resulting in inaccurate attendance

[0004] In addition, primary and middle school students leave school earlier, generally earlier than office workers, and some students who do not have parents to pick them up lack certain safety guarantees. Based on safety considerations, a positioning function should be added so that parents can know the location of students at any time

At present, most of them are smart watches for students. The major disadvantages of smart watches are too many functions, too fast battery consumption, and they will lose their function when the power is turned off. They are easy to forget due to the need for frequent charging.
