Abstract

Se presente un metodo para detectar y tratar de corregir una falla autogena de la tachuela del relevador en sus contactos. Este metodo percibe la falla en los contactos del relevador para abrirse una vez que se ha pedido el viaje. Esta deteccion puede detectar directamente condiciones de retransmision o indirectamente determinar la falla mediante un sensor de un sistema de parametros que muestra los efectos de la falla. Una vez que la falla del retransmisor para abrirse se ha determinado, el retransmisor nuevamente se energetiza para tratar de soltar la junta de la tachuela del relevador. Si el relevador falla para abrirse despues del primer intento, se puede repulsar de nuevo, de preferencia un reloj o timer de retransmision se emplea para asegurar que el sistema se ha estabilizado antes de que se intente un repulso. Un timer de pulso de relecador se puede emplear para controlar la duracion del pulso durante estos intentos. El numero de intentos tambien puede estar limitado.
