Abstract
The invention relates to the field of optically-carried information technology and provides a method and device for optically-carried information transmission based on full-spectrum LEDs. The method addresses the problem of visual perception interference caused by multi-color LEDs used for data transmission in the prior art. The method includes: dividing the data to be transmitted according to the first transmission demand information, obtaining a second preset number of data segments; selecting target monochromatic LEDs based on the luminous characteristics of the LEDs and the first transmission demand information; processing the data segments using the target LEDs and preset modulation algorithms to generate corresponding LED control signals; and controlling the target LEDs to transmit optically-carried information based on the control signals. This invention ensures optical communication performance while effectively reducing interference, thus improving the reliability of the optically-carried information system.
