A novel identification system based on visible light communication

A identification system based on visible light communication using white light emitting diode (LED) of the miner's lamp has been proposed and demonstrated, in which the Tag and Reader have been designed and realized. The Manchester encoding is presented to transmit identification number from the Tag to the Reader. The novel identification system could substitute for the in being radio frequency identification system to implement the checking attendance, person position and tracking in coal mine and in other LED illumination case.
