ABSTRACT:
The operation control section of an elevator system is constituted of two computers one of which shares the processing function with the other. One of the computers has a means for detecting an abnormality occurring in the other computer and stores therein a program for bringing the elevator cage to the nearest floor when the cage is stopped in an intermediate position between floors. If one of the computers falls in a fault, the cage is immediately stopped for assuring the safety of passengers. If the cage is stopped in the position between floors, the other computer causes the cage to be moved to the nearest floor for the rescue of the passengers.
