摘　　要：高校扩招使其对学生的管理难度有所增加,原有考勤管理系统的识别匹配度低下,无法达到管理需求,为此提出基于生物识别技术的高校实验室考勤管理系统设计研究。在原有的硬件结构中,增加人机交互模块,选用GM8125型号串口扩展芯片,将单片机与无线传输和指纹识别模块相连接,采取多通道模式,提高子串口波特率;采集学生的指纹图像,将图像均衡化处理,增强对比度,提取特征信息,划分用户权限等级,利用计算机程序完成用户的权限设置,实现基于生物识别技术的高校实验室考勤管理系统设计。提出仿真对照实验,测试所设计系统性能。测试结果证实,与原有系统相比较,经过优化设计的考勤管理系统对学生指纹的识别匹配程度有明显提高,且系统运行状态稳定,能够满足高校实验室考勤管理的工作需求。The expansion of university enrollment makes its management to the students more difficult,so the original attendance management system has been unable to meet the management requirements because its identification matching degree is low.Therefore,the design and research of a university laboratory attendance management system based on biological recognition technology are proposed in this paper.In the original hardware structure,the human⁃computer interaction module is added,GM8125 serial port expansion chip is selected,the single⁃chip computer is connected with the wireless transmission module and fingerprint identification module,and the multi⁃channel mode is adopted to improve the baud rate of the sub serial port.The fingerprint images of students are collected and balanced,enhance the contrast,extract the feature information,divide the user authority level,and use the computer program to complete the user′s purview setting.The design of university laboratory attendance management system based on biometric technology is realized.The simulation contrast experimental results indicates that,in comparison with the original system,the optimized attendance management system improves the matching degree of students′fingerprint identification significantly,and runs stably,which can meet the needs of attendance management in university laboratory.
