ELEVATOR RUNNING CONTROL DEVICE AND CONTROL METHOD IN POWER FAILURE

PROBLEM TO BE SOLVED: To shorten the time required for all elevators to land an arbitrary floor by effectively making use of the capacity of a private power generation device during the power failure in commercial power supply. SOLUTION: The capacity of a private power generation device can be effectively made use, and the time required for all elevators to return to their home positions can be shorten by an elevator running control device during power failure, which is provided with a running command section 3 during power failure, which detects the switching of a commercial power supply 1 to a private power generation device 2 when the commercial power supply 1 is failed in and commands each elevator to run during power failure, and a data table 5 in which control data for controlling the running of each elevator are stored, and an elevator returning control section 4, which controls the landing of each of all elevators to an arbitrary floor based on the control data so that the total of the capacity of the power supply required for the running of each elevator does not exceed the capacity of the private power generation device by commands.
