Abstract

Un sistema de comunicación a través de luz visible y su método correspondiente, en donde el canal de transmisión de la luz visible, tiene condiciones anormales, por ejemplo en túneles de una mina subterránea con alto grado de concentración de polvo en el ambiente, y además, en túneles rurales y urbanos, en donde el humo que se pudiera generar por algún tipo accidente, produciendo altas concentraciones de material pulverulento en el canal de trasmisión. Este problema se resuelve, utilizando en el sistema un transceptor de transmisión de luz visible, un medio de recepción de luz visible y una Red Neuronal Profunda (DNN, Deep Neural Network), con una determinada disposición, cercanía o alejamiento, de los transceptores de techo conformados por lámparas LEDs (arreglo de una multiplicidad de LEDs) y los Digital-Single Lens Reflex o D-SLR (conformados por cámaras de reflejo en la que la lente que se forma la imagen que también se proporciona como imagen al visor), en donde en conjunto con todos los elementos constitutivos del sistema, permiten limpiar el ruido del canal, pudiendo transmitir con luz visible con diversidad, aunque al ojo humano dicho canal aparezca interrumpido.
