Abstract

Se da a conocer un sistema de advertencia de informacion de trafico para transportar de trafico desde un sitio de consultoria de trafico a un vehiculo. El sito de advertencia de trafico comprende un vehiculo de emergencia, un peligro de un sitio a un lado de la carretera, o lo similar. El sistema comprende un transmisor adaptado para colocacion en el sitio de consultoria y un receptor adaptado colocacion en el vehiculo. El transmisor incluye un primer oscilador para transmitir una primera senal portadora y un segundo oscilador para transmitir una segunda senal portadora que tiene una segunda frecuencia portadora. La primera frecuencia portadora y la segunda frecuencia portadora estan separadas por una diferencia de frecuencias previamente determinada. El transmisor tambien incluye un modulador para modular ambas senales portadoras con una senal moduladora identica que refleja una situacion de trafico. El receptor incluye circuteria de exploracion, en la forma de un microprocesador, para explorar a traves de un intervalo de frecuencias previamente determinado para detectar senales portadoras separadas por la diferencia de frecuencia predetermina y un desmodulador para recuperar una primera senal moduladora recuperada de la primera senal portadora y una segunda senal portadora recuperada de la segunda senal portadora. El receptor tambien usa al microprocesador para comparar la primera senal moduladora recuperada con la segunda senal moduladora recuperada y para determinar si la primera y segunda senales moduladoras recuperadas son identicas. Adicionalmente el receptor incluye un dispositivo anunciador para anunciar un mensaje respecto a la situacion de trafico.
