CAN 기반의 가시광 조명통신에 관한 연구

Abstract

This paper is on novel use of lighting or signaling devices constructed by light-emitting diodes. In other words, the idea is on their concurrent use for simultaneous signaling and communications. LEDs offer advantageous properties such as high brightness, reliability, lower power consumption and long lifetime. So if LEDs replace half of all incandescent and fluorescent lamps currently in use, we could save equivalent output of power plants and reduce the production of greenhouse’s gases. On this advantage, we organized this dual function of LED, for lighting and communication, emerges interesting applications using voice messages and text-file’s transmissions alternately. This paper describes not only voice message’s transmission from the MP3 player but also text-file with serial communications.

Then, We are planning more applications using the CAN communication and we will realize concurrent use LEDs based on the CAN communication line for shipping craft and vehicle industry.

The market of ship building has been the world economy progresses also NMEA2000 protocol based on CAN is approved as a standard network of SOLAS ship. It is important to secure the core technology of ship electronics and IT convergence material. Also CAN is "Open network system".

Open standard for electronics, electrical and engine data all on the same network and Exchange of data between multiple manufacturers equipment simultaneously, marine manufacturers collaborating and creating an "Open" network environment.

so if illuminations in the ship are replaced with LEDs, Visible light communication based on CAN is possible to approach various ship networks and occur compatible operation with many kinds of devices.

So I would like to suggest that applications relevant to the CAN are possible to be adapted with LED's Infrastructure to many industrial things.

This paper is encouragement to guide fundamental truth and accelerate many applications regarding visible Light communication systems based CAN.
