Abstract
UN SISTEMA DE CIRCUITO DE VIA COMBINADO CON UN SISTEMA DE CONTROL AUTOMATICO PARA VEHICULOS SOBRE RAILES, EN EL QUE LA TRANSMISION DE INFORMACION Y DE DETECCION DE LOS VEHICULOS SOBRE RAILES EN EL SISTEMA TIENE LUGAR MEDIANTE EL INTERCAMBIO DE MENSAJES DIGITALES EN FORMA DE TELEGRAMAS. LOS TELEGRAMAS POSEEN CONTENIDOS CON INFORMACION DE SEGURIDAD, SOBRE TODO, INFORMACION SOBRE LA IDENTIDAD DEL CIRCUITO DE VIA PERO TAMBIEN PUEDEN SER DE CONTENIDO GENERAL. UNIDADES ELECTRONICAS SEPARADAS (E1,E2) GENERAN DOS TELEGRAMAS CON EL MISMO CONTENIDO INFORMATIVO. ESTOS TELEGRAMAS SON COMPARADOS ANTES DE SU TRANSMISION AL CIRCUITO DE VIA (2), EN EL QUE UN RECEPTOR (B) RECOGE EL TELEGRAMA. LOS TELEGRAMAS TRANSMITIDOS Y RECIBIDOS SE COMPARAN PARA CONSEGUIR UN SEGURIDAD EN CASO DE ERROR. LA INDICACION DEL NIVEL DE LA SEÑAL RECIBIDA DA INFORMACION SOBRE SI EL CIRCUITO DE VIA ESTA OCUPADO. SE UTILIZA UNA SEÑAL DE SALIDA (4) DEL SISTEMA COMO SEÑAL DE SEGURIDAD EN CASO DE ERROR PARA ALIMENTAR A UN SISTEMA DE CONTROL DE TRAFICO.A VIA CIRCUIT SYSTEM COMBINED WITH AN AUTOMATIC CONTROL SYSTEM FOR VEHICLES ON RAILS, IN WHICH THE TRANSMISSION OF INFORMATION AND DETECTION OF VEHICLES ON RAILS IN THE SYSTEM HAS A PLACE THROUGH THE EXCHANGE OF DIGITAL MESSAGES IN THE FORM. TELEGRAMS HAVE CONTENT WITH SAFETY INFORMATION, ABOVE ALL, INFORMATION ABOUT THE IDENTITY OF THE VIA CIRCUIT BUT MAY ALSO BE OF GENERAL CONTENT. SEPARATE ELECTRONIC UNITS (E1, E2) GENERATE TWO TELEGRAMS WITH THE SAME INFORMATION CONTENT. THESE TELEGRAMS ARE COMPARED BEFORE THEIR TRANSMISSION TO THE VIA CIRCUIT (2), IN WHICH A RECEIVER (B) COLLECTS THE TELEGRAM. TELEGRAMS TRANSMITTED AND RECEIVED ARE COMPARED TO GET SAFETY IN CASE OF ERROR. THE INDICATION OF THE RECEIVED SIGNAL LEVEL GIVES INFORMATION ABOUT IF THE VIA CIRCUIT IS OCCUPIED. A SYSTEM EXIT SIGNAL (4) IS USED AS A SAFETY SIGNAL IN CASE OF ERROR TO SUPPLY A TRAFFIC CONTROL SYSTEM.
