摘要:

针对无线图像传输系统抗干扰能力差、保密性低等问题, 设计并研制了基于可见光通信的图像传输系统。该系统采用51 单片机为主要控制器, 以发光二极管发出的高速调制可见光作为信息载体, 利用光电二极管接收光载波信号, 并通过PC 机获得图像信息, 实现了基于可见光通信的无线图像传输。实验结果表明,该系统抗电磁干扰能力强、成本低、功耗小、安全性好, 在通信距离为0. 7 m 时, 其最大位传输速率为0. 1 Mbit/ s, 误码率小于10-5 , 有效克服了现有图像无线传输系统的固有问题, 是短距离无线通信技术很好的补充, 具有很好的应用前景。

Abstract:

Because the existing wireless image transmission system has poor anti-interference ability and low confidentiality issues, an image transmission system based on VLC(Visible Light Communication) is designed.51 processor is used as the main controller, using visible LED(Light Emitting Diode) high-velocity modulation as information carrier, visible light of high-speed modulation emitted from the LED is utilized as information carrier,photodiode is utilized to receive optical carrier signals, the image information is obtained through the PC,wireless image transmission based on visible light communication is realized. The results show that the maximum bit transfer rate of the device is 0. 1 Mbit/ s when the communication distance is 0. 7 m, the BER(Bit Error
Rate) is less than 10-5. The system effectively overcomes the problems inherent in the conventional image transmission system of the wireless, it is a good supplement for short-range wireless communications technology,having a good prospects.

Key words: visible light communication (VLC), image transmission, white light emitting diode (LED)
