Abstract

MEJORAS INTRODUCIDAS EN UN CONTROL DE MAQUINA POR PROCESADORES MULTIPLES.CONSISTENTES EN QUE EL MOTOR INCLUYE UNA PLURALIDAD DE PROCESADORES REMOTOS QUE CONTROLAN PARTE DE LOS ELEMENTOS CONTROLADOS, MANTENIENDO CADA UNO DE ELLOS UNA INFORMACION DE ESTADO QUE CORRESPONDE A UNA PARTE DE LOS ELEMENTOS CONTROLADOS; UN PROCESADOR PRINCIPAL QUE RESPONDE A UN DEFECTO DE FUNCIONAMIENTO DEL CONTROL; UNAS LINEAS DE PUESTA A CERO QUE INTERCONECTAN EL PROCESADOR PRINCIPAL CON LOS REMOTOS; UN CIRCUITO DE PUESTA A CERO CONECTADO CON CADA UNO DE LOS PROCESADORES REMOTOS QUE RESPONDE AL PROCESADOR PRINCIPAL; Y UN DISPOSITIVO DE ACTIVACION PARA QUE EL PROCESADOR PRINCIPAL ACTIVE EL CIRCUITO DE PUESTA A CERO Y PONGA A CERO UN PROCESADOR REMOTO EN RESPUESTA A UN DEFECTO EN EL FUNCIONAMIENTO DEL CONTROL, CON LO CUAL LA INFORMACION SOLO SE PIERDE PARA EL PROCESADOR REMOTO PARTICULAR Y SE MANTIENE PARA EL RESTO DE PROCESADORES REMOTOS.
