摘要
针对传统课堂考勤签到用时长且数据不易管理的问题,基于RFID技术的自动识别和非接触通信功能设计并实现了面向大众化的考勤系统。本文论述以STC89C51单片机作为主控模块,结合以MFRC522芯片为核心的无线射频识别模块,同时配合外围存储、显示以及报警模块;并在QT软件平台设计上位机软件实现了对非接触IC卡的写入、读取等功能,对持卡人的权限进行管理,并对考勤人数、考勤时间等进行统计;系统在日常生活生产中有较好的实用价值。
Aiming at the problems of the traditional attendance check-in and the data is not easy to manage,the paper designs and implements the attendance system for the masses based on the RFID technology’s automatic identification and non-contact communication function.This paper discusses the STC89C51 microcontroller as the main control module,combined with MFRC522 chip as the core of the radio frequency identification module,with peripheral storage,display and alarm module;In addition,upper computer software was designed on QT software platform to realize the functions of writing and reading of non-contact IC cards,manage the authorization of cardholders,and make statistics on attendance number and time.The system has good practical value in daily life.
