Automobile Collision Warning and Identification System using Visible Light and Wi-Fi Communication

This paper introduces a vehicle-to-vehicle (V2V) communication system based on visible light communication technology. A vehicle will transmit the data continuously to another vehicle in front of it using head light and the data is stored in the Secure Digital (SD) Card in comma separated value for future reference in case of emergency at the same time the data is stored in the cloud server for government reference for locate the most accident areas. Nowadays, people readily use internet in their day-to-day activities to accomplish their task by means of wireless or wired network. As users are increasing manifold, data transmission rate consequently decreasing. However, Wi-Fi imparts data rate of 150Mbps as per IEEE 802.11n, this speed is still not enough to suffice the needs of a user. Considering this, Visible light communication concept has been introduced. In this project, a comparative and analytic study about the speed of visible light and Wi-Fi communication is being done and also reduction of network jamming problem due to increasing users demand is also being done.

This design is based on Visible Light Communication Technology, to achieve outdoor visible light communications and image recognition etc. through traffic lights. It will play a role on promoting the utilization of traffic lights. The system uses a LED dot matrix to imitate the traffic light, loading QR Code information on the LED dot matrix and then transporting it in a very high-speed flashing. In receiving terminal, first, webcam OV7670 collects information which from the LED dot matrix, then conveys the picture to FPGA, which is the processor. FPGA will handle the picture by gray scale processing, medium filtering and binary processing at last. Thus, the picture from the LED dot matrix will change to ‘0’ and ‘1’ in binary area. Secondly, as there’s a relationship between LED dot matrix and webcam pixels, we can count how many pixels represent one LED. Finally, we can decode the QR Code based on its own style, and display the final result on the TFT screen.

The Impact

Visible light communication technology is a emerging wireless and optical communication technology developed after invention and application of white LED.In this paper, we have a research based on indoor visible light communication system of lighting white LED,discuss of the visible light communication channel characteristics,detailedly analysis of the indoor visible light communication link. This paper focuses on the modulation and demodulation method applied to visible light communication. In the past visible light communication is mainly used off keying modulation,however, the data transfer speed is limited due to the influence of ISI .This paper presents a solution based on OFDM modulation and demodulation, to reduce the impact brought from inter-symbol string under high data transfer speed.Based on data analysis and computer simulation,the program presented in this paper can be used as indoor lighting and high-speed data transmission.Finally, give scheme to achieve visible light communication modulation and demodulation,provide a theoretical basis for further experiments.
