摘　　要：依据指纹唯一性和终身不变的特征,设计了一种基于指纹技术的电子门锁控制系统。该控制系统采用三级网络结构:底层由FPS200指纹传感器芯片采集指纹图像,经中间层网络交换机传送到监控主机对指纹图像进行增强、匹配等处理,然后输出控制信号经PLC来驱动电控锁具执行开关门动作,可以实现一台主机多个锁具的集散自动控制。在此控制系统开发过程中,结合市场前景及需求,重点对指纹采集方案、系统功能、指纹识别算法进行了详细的探讨。该控制系统适合于酒店客房、综合办公、证券、库房等场所。Designed an electronic lock control system based on fingerprint technology, judging by fingerprint uniqueness and the all self＇s life invariant characteristic. This control system was composed by trilevel network architectures： fingerprint image by gathered from the first floor with FPS200 fingerprintsensor chip, and it transmitted to the control computer from Message Switching Unit. Furthermore, fingerprints were enhanced and matching by the control computer. At last output control signals control the door switch by the PLC. With the market prospect and the demand, we researched the fingerprint gathering plan, the system function and fingerprint recognition algorithm mainly during the period of designing the control system. Many distributed Locks can be control with a host computer in this control system. It＇s mainly suitable for hotel rooms, office complex, securities, the Treasury and other nlaces.
