摘要
随着通信技术与半导体技术的不断发展,基于发光二极管(Light Emitting Diode,LED)的可见光通信技术在技术应用创新中显现出巨大优势。将该技术应用于智能锁设计领域,设计了一款基于现场可编程门阵列(Field Programmable Gate Array,FPGA)的可见光智能安全系统,该系统由FPGA、可见光通信发射电路、可见光通信接收电路以及电力锁等部分组成。这种智能安全系统通过将用户密码调制到光信号上进行传输,可以防止有效信息被窃取,从根源上解除特斯拉线圈对传统锁具安全的威胁。
With the continuous development of communication technology and semiconductor technology,visible light communication technology based on Light Emitting Diode(LED)has shown great advantages in technological application innovation.Applying the technology to the field of intelligent lock design,a visible light intelligent security system based on Field Programmable Gate Array(FPGA)is designed.The system is composed of FPGA,visible light communication transmitting circuit,visible light communication receiving circuit and power lock.This intelligent security system can prevent effective information from being stolen by modulating the user’s password to the optical signal for transmission,and fundamentally remove the threat of Tesla coil to the security of traditional locks.
