摘　　要：针对传统考勤方式管理效率较低、统计工作复杂以及考勤准确性差等缺点,采用STC12C5A60S2单片机作为核心控制芯片,提出了基于单片机的智能指纹考勤系统总体设计方案,研究分析了系统的核心技术和工作流程,设计了一种基于单片机的指纹考勤系统,通过STC12单片机和指纹识别模块采集考勤信息,利用上位机实时查看考勤状态,实现了企事业单位的自动考勤和考勤数据的分析处理。实验测试结果表明,智能考勤系统具有操作简单,统计速度快,考勤准确性高等特点,能够有效防止代人打卡、签到和迟到早退等现象,节省了考勤时间,提高了管理效率,提升了企事业单位考勤管理的信息化水平,具有一定的实用推广价值。In view of the shortcomings of traditional attendance pattern,such as low management efficiency,complex statistical work and poor attendance accuracy,it presents the overall design scheme of intelligent fingerprint attendance system based on single chip microcomputer. The core technology and workflow of the system are studied and analyzed,and the fingerprint attendance system based on single chip microcomputer is designed taking STC12C5A60S2 single chip microcomputer as the core control chip. The attendance information is collected by STC12 single chip microcomputer and fingerprint identification module. The system use the upper computer to view the attendance status in real time. It realizes the automatic attendance of enterprises and institutions and the analysis and processing of attendance data. The experimental results show that the intelligent attendance system has the characteristics of simple operation,fast statistical speed and high attendance accuracy and it can effectively prevent people from punching in,signing in and leaving late and early. It saves attendance time,improves management efficiency,and improves the informatization level of attendance management in enterprises and institutions. It has certain practical popularization value.
