基于ARM与条码技术的学生考勤系统设计

Design of Student Attendance System Based on ARM and Barcode Technology

为了有效保障学生考勤率,解决学生上课迟到早退问题,提出了一种基于ARM技术和一维条码技术的考勤系统。该系统利用一维条码技术制作考勤名片,利用ARM处理器、激光扫描器完成对考勤名片的识别。系统同时还具有电子时钟、语音播报器、液晶屏、操作按键、指示灯等部分,分别用于辅助完成考勤系统的时间同步、语音播报、液晶显示、打卡设置、打卡提示等任务。实验结果表明,该学生考勤系统考勤名片识别准确度高,电子时钟精确,语音播报功能完善,性价比高,操作简单,实用性强。

To guarantee effectively the student attendance rate and to solve the students tardiness problem as soon as possible,an attendance system based on ARM technology and barcode has been designed,in which one-dimensional barcode technology has been used to make attendance cards,ARM processor and laser scanner have been adopted to identify students’attendance cards.System consists of electronic clock,voice broadcast device,LCD,buttons and lights which assist to achieve respectively the functions of time synchronization,voice broadcast,display,punch settings and punch prompt.Experimental results have showed that the attendance system has many advantages such as high attendance card recognition accuracy,precise electronic clock,perfect voice broadcast function,high performance to price ratio,easy operation and strong practicability and so on.
