摘　　要：设计了一款基于手机闪光灯的可见光门禁系统,利用编写的手机应用程序(APP,application)控制手机上的后置摄像头闪光灯作为光源,调制光信号,发送手机的ID身份信息和密码,配备光信号接收电路的门禁系统接收光信号,并解调出ID和密码,若和初始设置的密码一致,电磁锁打开,同时识别出机主的ID身份信息,可以实现考勤功能。本文系统灵敏可靠、成本低和使用方便。A visible light access control system based on mobile phone flash is designed. The popular rear camera flash of mobile phone controlled by a written is used as a light source,then optical signal is mod- ulated, and ID information and system password are sent to the access control system. The access control system equipped with optical signal receiving circuit can receive the optical signals, and demodulate the ID information and password are demodulated. If the password is the same as the initial setting, access control is unlocked. At the same time, the system has attendance function by identifying the owner＇s ID information. The system is sensitive and reliable, low cost and easy to use.
