ABSTRACT
With the increasing number of students in ordinary colleges and universities, the number of
students increases sharply and the management becomes more and more difficult. How to
optimize the daily management of students has become a popular problem. Student attendance
system should be able to provide managers with detailed student personal information and fast
means of attendance, so the development of a student attendance system is very necessary, the
system must adapt to the computer information management system, and has a certain
development value. It has been observed that RFID technology is a kind of communication
technology, which can identify specific targets and read and write related data through radio
signals, without establishing mechanical or optical contact between the identification system and
specific targets, which can just be applied to the design of student attendance system.
The goal of this project is to develop a student attendance record and management of the
attendance system. The main design of a low-cost high-performance RFID card reader. RFID
card reader circuit design needs to achieve low cost and high performance, and the attendance
system highlights the convenient and simple management function.
The whole RFID attendance system mainly includes RFID card reader, wireless/serial
communication module, identification attendance system. Legibility decoding and the identity of
the card information via a serial port/wireless communication module is sent to PC identification
attendance system attendance record and management, implement the read from the RFID card,
data transmission, a series of functions such as attendance records and statistics of the complete
system implementation plan, improved the existing ways of check on work attendance, improve
the efficiency of the attendance.
The hardware part of the system includes: RFID card reader single-chip microcomputer
control circuit design, reader RFID modem rf front-end circuit design, NRF24L01 wireless
communication module design, PL2303 usb-uart serial communication module design.
The work of the system software includes: the upper computer of the system adopts
client/Server mode, the background database USES SQL Server database management software,
the database SQL language operation based on Visual C++, usb-uart serial communication and
