首发时间:2017-08-11
摘要:室内无线光通信随着LED技术基于白光LED的室内可见光通信系统的快速发展而迅速崛起,白光LED照明逐渐替代传统照明方式,为室内可见光通信的实现提供了稳定高效的光源。基于白光LED的室内可见光通信除了满足日常照明的需求以外,更能为室内设备提供数据传输。这种方式和传统电磁波传递相比,有无电磁辐射、保密性好、无需额外频谱资源等优势,白光LED可见光通信和家庭、办公场所、公共场所相结合能在达到照明通信目的的同时,更能实现机舱、医院等敏感区域的数据通信。 本文从系统各功能模块入手,通过分析其功能和需求,设计了发射、接收系统。选取直接链路方式和强度调制搭建系统,设计并制作了发射、接收电路。实验结果表明,该方案能实现室内可见光通信的传输要求,得到了较好结果。

Indoor Visible Light Communication System Based On White Light LED
Abstract:Indoor wireless optical communication is developing rapidly with the development of LED technology. White LED lighting is gradually replacing the traditional lighting,indoor visible light communication has a stable and efficient light source. Indoor visible light communication based on white light LED can meet the needs of daily light and data transmission for equipment. Compared with the traditional electromagnetic wave transmission, it hasmany advantages such as electromagnetic radiation, security, no need of additional and spectrum resources. Starting with the functional modules of the system, this paper designs a transmitting and receiving system. The author chooses the direct link mode and the intensity modulation system to design and make the transmitting and receiving circuit. Experimental results show that the proposed schIndoor Visible Light Communication System Based On White Light LEDeme can achieve the indoor visible light communication requirements, and get good results.
