摘要
基于ARM架构的嵌入式无线指纹考务管理系统内置指纹采集识别功能模块,采用无线网络通信和以太网通信结合的通信方式,与中央数据库保持软实时交换数据.系统采用Access数据库管理用户基本的常规信息和用户指纹特征信息数据,运行可靠;充分发挥嵌入式系统的特点,使用灵活方便.实验结果表明对指纹识别的拒识率低于1%,指纹识别的误识率接近0.系统可用于大规模考试管理,实用于远程网络化的考试管理,具有许多传统方法不能实现的功能,是考务管理的发展方向.
The embedded wireless fingerprint examination management system based on ARM had the internal fingerprint acquisition recognition function module, adopted the wireless network communication unit and the ethemet communication unit to realize the real-time data exchange between the embedded wireless fingerprint examination management system and the central data base. The system worked reliably because Access database software was used to manage the user basic information and the finger character, and it had good facility because the embedded characteristics were exerted adequately. The results of experiments declared false accept rate was 0 and false reject rate was 1%. This system can be used to manage large scales examinations, and can be applicable for the longrange examinations on network, and it can also realize some functions which can＇ t be realized by the conventional ways. So it is the new direction of the examination management.
