When having a power failure of elevator operational manner

摘要

PROBLEM TO BE SOLVED: To perform safe and optimal power failure time operation by switching it to supply of an emergency power source at power failure time, detecting an arrival of a car at the recall floor when emergency recall operation at fire time is detected at this time, and generating a return command to the other cars when the arrival is detected. ;SOLUTION: In the case where recall operation of a car #1 machine is performed, power failure is caused, and when a private power generation power source is established, a group control board 1 judges whether or not the car #1 machine completely returns to the designated return floor, and in the case of NO, a return command is outputted to a respective unit control board 2a. The car #1 machine arrives at the recall floor, and opens a door, and when the completion of an arrival is detected by a position detector or the like, a CPU 22a stops operation of the car #1 machine after the completion of a return is outputted to the group control board 1 even if the return floor and this time arrived recall floor are not the same. The group control board 1 outputs a return command to a car #2 machine by judging whether or not a return is completed by transmission of the completion of a return.;COPYRIGHT: (C)1997,JPO
