Abstract

Sistema de detección de estado en monitores, que consta de un circuito captador de presencia de imagen que incluye, al menos, un conductor óptico, conectado a cada monitor a controlar y asociado a un sensor óptico que transforma la luz contenida en la imagen en tensión y la envía a una de las entradas de un comparador controlado por microprocesador y en el que existe otra entrada con una tensión de referencia (V0); de modo que el comparador genera una señal de salida siempre que la tensión procedente del sensor óptico supere el citado valor (V0). De aplicación en electrónica.Status detection system on monitors, consisting of an image presence sensor circuit that includes at least one optical conductor, connected to each monitor to be controlled and associated with an optical sensor that transforms the light contained in the image into tension and sends it to one of the inputs of a comparator controlled by microprocessor and in which there is another input with a reference voltage (V0); so that the comparator generates an output signal whenever the voltage coming from the optical sensor exceeds said value (V0). Application in electronics.
