Abstract

Un sistema y método para detectar condiciones de falla en un dispositivo de registro (38) colocado de un vehículo (12) que tiene uno o más sensores vehiculares (48) para monitorear uno o más parámetros operacionales del vehículo (12). El dispositivo de registro (38) se utiliza para colectar datos de operacion del vehículo producidos por los sensores (48). Una implementacion de la técnica de deteccion de fallas involucra el almacenamiento de un valor de tiempo actual en intervalos regulares durante periodos en los cuales el dispositivo de registro está provisto con una fuente de poder principal. Las diferencias de tiempo se determinan entre los consecutivos de los valores de tiempo almacenados, y las diferencias de tiempo se comparan con un valor máximo predeterminado. Una condicion de falla por pérdida de potencia se registra cuando al menos una de las diferencias de tiempo excede el valor máximo predeterminado. Una indicacion de la existencia de la condicion de falla por pérdida de potencia puede ser comunicada a una estacion de control central (18) mediante el dispositivo de registro (38).
