PURPOSE:To avoid receiving a cage call having arrived at just a minute earlier due to erroneously forecasted arrival time by making a group management control section detect the case of the cage call where its arrival at just a minute earlier is forecasted, based on the conditions of respective elevators, and thereby delaying the door opening operation of the elevator answering to the cage call. CONSTITUTION:A group management control section 1 detects the case of a cage call where its arrival at just a minute earlier is forecasted, based on cage information 7. When there arrives a cage call to an elevator running to the regular direction at a floor to be stopped next, and when the difference in arrival time from an allocated elevator is within a definite time, the aforesaid control section issues a start delay command 6B to the single control section 2 of the elevator which has accepted the cage call with the arrival of the cage call forecasted. Furthermore, when it is detected that the difference in arrival time between the elevator which is being decelerated since it accepted the cage call and the allocated elevator is within a definite time, the control section 1 issues a door open delay command 6A to the single control section 2 of the elevator which has accepted the cage call. In this case, when the command 6B is issued, after a definite time has elapsed since a door was closed, a start command 8 is issued to a motor control section 4. And when the command 6A is issued, a door open command is issued, so that the door is thereby opened after the elevator has been completely stopped. |
