Abstract:
The invention relates to a system for communication by means of visible light and to the corresponding method, where a channel for transmitting visible light has abnormal conditions, for example, in tunnels of an underground mine with a high degree of dust concentration in the atmosphere and also in rural and urban tunnels in which the fumes generated by an accident produce high concentrations of powdery material in the transmission channel. This problem is solved by using in the system a transceiver for transmitting visible light, a means for receiving visible light, and a Deep Neural Network (DNN), with a specific arrangement, proximity or distance, of ceiling-mounted transceivers formed by LEDs lamps (arrangement of the plurality of LEDs) and Digital Single Lens Reflex (D-SLR) transceivers (formed by reflex cameras in which the lens that forms the image also provides the image in the viewfinder). According to the invention, together all the elements forming the system allowing channel noise to be removed, being able to transmit using visible light with diversity, even if the channel appears interrupted to the human eye.

Claim (Index 3):
A communication method through visible light, where the visible light transmission channel, has abnormal conditions, for example in tunnels of an underground mine with a high concentration of dust in the environment, and also, in rural tunnels and urban, where the smoke that could be produced by some type of accident, produces high concentrations of pulverulent material in the transmission channel, which has means to create a number of cells, based on the lighting of an array of LEDs and a Digital-Single Lens Reflex or D-SLR, located on the roof of the tunnel and transceivers of LED/D-SLR connected to people or vehicles inside the tunnel, WHEREIN the method consists of the following stages:\n (a) transmitting data according to the following steps:\n (a1) entering data from the location of the roof transceiver and the location of transceivers of people or people and vehicles within the tunnel; \n (a2) means for serial/parallel conversion of data, creating of a sequence that includes the number of the cell and an identifier for people or machines within the tunnel; \n (a3) a means to create frames as to build a data frame; \n (a4) modulating the data frame; \n (a5) directing the LEDs to a breaking down means; \n (a6) breaking down the LED signal in three colors Red, Green, and Blue (RGB), as to activate all three colors in parallel; and \n (a7) transmitting the frame of colors; \n (b) sending said frame using a visible light communication channel; (c) receiving the data frame according to the following steps:\n (c) receiving the data frame; \n (c2) detecting the data frame; \n (c3) representing the inverse of the channel for each of the RGB colors and to remove the accompanying symbols of the RGB data, thus cleaning the signals by using a Deep Neural Network (DNN); \n (c4) demodulating the data frame; \n (c5) breaking down data as to return them to their serial version; \n (c6) converting serial/parallel data as to deliver clean output data; \n (c7) provide data output.
