Abstract
ESTA BARRERA DE LUZ DE HORQUILLA BICANAL EN VERSION "FAILSAFE" GENERA INFORMACIONES EN LAS ZONAS DE LAS PLANTAS PARA LA APERTURA ANTICIPADA DE LAS PUERTAS DE LAS CABINAS DE ASCENSORES Y MUESTRA UN AUTOCONTROL (ZDU, 6) CICLICAMENTE DINAMICO, LO CUAL POSIBILITA UN RECONOCIMIENTO PROFILACTICO DE FALLOS. AL LLEGAR Y PARARSE UNA CABINA EN UNA PLANTA, EL ZDU (6) SIMULA UN PROCESO DE FUNCIONAMIENTO PERIODICAMENTE AUTENTICO, SIMULANDO UNA BREVE INTERRUPCION DE LA CONEXION MEDIANTE CORTOCIRCUITO OPTICO DE LA BARRERA DE LUZ-FS. ESTO PRODUCE UNA INTERRUPCION EN LA ALIMENTACION DE LOS RELES, LA CUAL ES SIN EMBARGO MAS CORTA QUE EL TIEMPO DE DESACCIONAMIENTO DE LOS RELES, DE MODO QUE ESTOS NO SE DESACCIONAN, SI LA CONEXION ESTA INTACTA. UN CICLO SECUENCIAL DE SEÑALES DE TIEMPO (TA/B1..4, TVB) DIRIGE EL DESARROLLO DE LAS FUNCIONES DE AUTOCONTROL. EN CASO DE ALGUN FALLO EN LOS COMPONENTES, ESTE PROCESO ES PERTURBADO Y SE PRODUCEN, POR MEDIO DE LOS CONTACTOS DE LOS RELES, LAS CORRESPONDIENTES REACCIONES ENLOS CIRCUITOS DE SEGURIDAD DEL MANDO DEL ASCENSOR. UNA SEÑAL DE CONTROL QUE SE PRODUCE CICLICAMENTE (TSA, TSB) ES LA SEÑAL DE MANDO PRIMARIA PARA INTERRUPCIONES SIMULADAS.
