ELEVATOR CONTROL SYSTEM AND ELEVATOR CONTROL METHOD

摘要

An elevator control system is equipped with: an upper-car control device and a lower-car control device which independently control an upper car and a lower car, respectively, for moving in a shared elevator shaft provided with an express zone; and a group management device for managing the upper-car control device and the lower-car control device as a group. The group management device determines the movement direction of an emergency-stopped car on the basis of the respective positions of the upper car and the lower car, and the floor positions at which it is possible for the upper car and the lower car to stop, when the upper car and/or the lower car are/is emergency-stopped inside the express zone as a result of emergency-stopping because an earthquake sensor sensed an earthquake, and when performing a rescue operation for moving the emergency-stopped car(s).
