摘要学生考勤管理是高校教学管理的重要组成部分，是教学活动正常开展的前提，而很多高校还在使用人工方式统计和管理学生考勤信息。随着科学技术的迅猛发展，这种方式逐渐显现出效率低下、准确性差等弊端。结合网络信息时代“数字化”校园建设这一思想，根据华北电力大学学生管理的特点，现设计了基于指纹识别技术的学生考勤管理系统。该系统是集课堂考勤、图书馆登到、实验室登到、学生宿舍登到等功能于一体的学生考勤管理系统。通过本系统，我们可以做到学生考勤信息的规范管理、准确统计、快速查询等，极大的提高了学生考勤信息管理的效率和水平。通过对使用对象（教务处领导、学生辅导员、实验室工作人员、任课教师和学生）的走访和调查，完成了学生考勤管理系统的需求分析，为后续的开发奠定了强有力的基础，降低了开发风险，保证了系统的质量。本系统是计算机技术和指纹识别技术相融合而形成的一套完善的系统。该学生考勤管理系统主要包括两个部分：学生日常考勤子系统和学生考勤管理子系统。其中学生日常考勤子系统的功能主要包括：日常学生考勤、学生指纹信息采集、指纹仪设置等。学生考勤管理子系统主要完成考勤记录的查询、统计、及考勤规则的设置等工作。该子系统主要功能包括：学生信息管理、教室信息管理、课程信息管理、课程表信息管理、管理员信息管理等。通过本系统，实现了对高校学生日常考勤信息的全面准确的管理。本系统采用目前比较流行、成熟的.Net 企业级应用体系架构，使用高效、稳定的 SQL Server 2005 数据库，具有很高的安全性和可靠性，及灵活的系统扩展性和良好的用户体验。关键词：学生管理；指纹识别；信息统计 I

Abstract The supervision of students’ attendance is an important part of college teaching management, which is also a premise of teaching. However, many universities still use manual basis to investigate and supervise students’ attendance information. With the dramatic development of technology, this method gradually shows its drawbacks, for example it is inefficiency and inaccuracy. Based on fingerprint recognition technology, we designed students’ attendance management system according to the idea of digital campus construction and the students’ management characteristics of North China Electric Power University. This system has multiple functions, including class attendance checking, library registration, laboratory registration and dormitory registration. This system makes personnel can investigate and check students’ attendance information rapidly and accurately, which improves work efficiency dramatically. Through interview and investigation to users (leader of academic administration, counselor, Laboratory staff, Instructor and students), we carried out the demand analysis of students’ attendance management system, which laid solid foundations to subsequent development, reduced the development risk and ensured the quality of the system. This system is based on computer technology and fingerprint recognition technology. It mainly includes two parts, which is daily attendance system and attendance management system. Daily attendance system’s functions include checking students’ daily attendance, collecting students’ fingerprint information and setting up finger print scanner. Attendance management system is used to investigate attendance information and set attendance rules, and its functions include students’ information management, classroom information management, course information management, curriculum information management, manager information management and so on. This system makes the management of daily attendance information comprehensive and accurate. This system adopt popular and mature Net Enterprise-level application architecture, used efficient and stable SQL Server 2005 database, which make the system safe, reliable and has flexible system extensibility and wonderful user experience. Keywords: students’ management, fingerprint identification, information statistics II
