摘      要：A real-time visible light communication(VLC) to universal asynchronous receiver/transmitter(UART) conversion system is made up of a transmitter with a light emitting diode(LED) and a receiver with a photodiode(PD), by which a VLC system is connected to traditional communication modes, and the data are transferred by wireless visible light. UART packets are converted to light packets by the modulation of a 10 k Hz on-off-keying(OOK) light signal, and the data losses in the transportation are avoided by the protection of a data buffer mechanism. The experimental results reveal that the real-time VLC to UART conversion system can provide a real-time VLC transmission way for two UART devices in not less than 10 m at a baud rate not less than 19 200 Bd with stable ambient lighting at the same time.
