A system and method of Communication through visible light, for a Mine underground Tunnels or similar.

摘要

A system of Communication through visible light, where the channel of transmission of visible light, has abnormal conditions, for example in an underground Mine Tunnels with high degree of concentration of dust in the Environment, and furthermore, in rural and Urban Tunnels, where Hu Mo could be generated by some accident,Produces high concentrations of Powdered material in the channel of transmission, which has means for generating a number of cells, on the basis of the illumination of an array of LEDs and a Digital Single Lens Reflex camera or d-slr, located on the roof of the tunnel and transceivers / D - SLR co LED Nectados people vehicles inside the tunnel, characterized in that it comprises:(a) comprising: a Transmitter? (A1) means of Data Entry;(A2) to the serial / parallel conversion, Data formed by a sequence of Cell number and an identifier or a few Machines inside the Tunnel;(A3) is a entramador chipformer for a Data frame; a Modulator (A4) upsk (undersampling shifh Phase keying) to modulate The Data frame;? (A5) a driver or Feeder LEDs;(A6) a means to decompose the signal of LED in three Shades of red, Green and Blue (RGB), Activating the three tones of Colours In parallel; and a Transmission medium (A7); (b) a Communication Channel of visible light; (c) a receiver formed by:? A reception means (C1) and (C2) Sensor Data frames;(C3) a Deep Neural Network (DNN) to represent the inverse of the channel for each of RGB COLORS and removing symbols that accompany the RGB Data, cleaning the signals; a DEModulator (C4); a means of desentramado (C5) that returns Data to its version number;? (c) a means for converting serial / parallel,Given the output Data (C7) Clean; a Data output means.
