MUTUAL FAULT DIAGNOSIS PROCESSING METHOD/DEVICE FOR MULTIPLEX CONTROLLER AND DEGENERATIVE MULTIPLEX CONTROLLER USING THE PROCESSING METHOD/DEVICE

摘要

PURPOSE: To ensure the mutual fault diagnosis among plural subsystems and also to avoid the downs of all system for improvement flexible operations of subsystems by separating the subsystems from a control system in a fault state based on the priority set previously among those subsystems. ;CONSTITUTION: Plural subsystems 10i-10k control a controlled system, e.g. an MG set 2 for a reactor 1. Then an input value is operated as prescribed at a logic part 11 in the system 10i for example. Meanwhile a mutual diagnosing part 12i compares its own arithmetic processing data Di with the data Dj and Dk received from the subsystems 10j and 10k respectively in order to diagnose the fault of its own system. A separating circuit 14i separates its own system from a control system based on the diagnosing result of the part 12i. When the faults occur among subsystems 10i-10k, these subsystems are separated from the control system based on the prescribed priority.;COPYRIGHT: (C)1994,JPO&Japio
