摘要
基于生物识别技术的门禁系统是目前最为安全的识别系统。设计的指纹门禁系统设计分硬件和软件2部分,硬件主要由计算机、指纹采集仪、门控制器及电锁、232/485转换器等部分组成。门控制器主要接收微机发出的开门信号以及发送开锁信号,且对非法开门进行报警。该系统的软件设计主要完成了人员信息管理、出入记录查询、通讯功能。
The access control system based on the biometric technologies is currently the most secure identification system. In this paper, the fingerprint access control system consists of hardware and software parts. The hardware part is composed of the major computer hardware, fingerprint collection device, controller and power door locks, 232/485 converter, etc. The access controller is mainly to receive the signals of opening the door and send the signals of unlocking. The alarm is used to receive the alarm signals from the access controllers in case of opening the door illegally. The system software is designed to complete the personnel information management, accesses the records of information and achieves the communication function.
