Elevator group management control device

Abstract

The present invention provides an elevator group management and control device. The device is provided with a plurality of lift car calling and registering parts (4) which are respectively arranged inside a plurality of lift cars (1) going up and down a hoist way; an elevator riding place calling and registering part (5) for registering calling of an elevator riding place; a single body control part (2) for controlling operation of the lift cars; and a group management and control part for optimizing the operation of the lift cars. The group management control part is provided with an elevator riding place calling information management part (7) for realizing registration control management of elevator-riding calling from the elevator riding place calling registering part; an obstruction operation state detection part (9) for detecting the situation of obstruction and operation state; an elevator-riding place calling and passing control part (10) for preventing distributing output control at least one lift car registered with lift car calling among the lift cars which are in the obstruction and operation state; and a distribution control part (9) for realizing distribution control of optimal lift cars chosen from the lift cars prevented to be distributed.

Description

technical field [0001] An embodiment of the present invention relates to an elevator group management control device capable of suppressing a blocked (sluggish) running state. Background technique [0002] In the group supervisory control system that controls a plurality of elevators, since the operation is controlled in consideration of the overall operating efficiency of the elevators, it is not always the nearest elevator that responds to the user's hall call. [0003] In addition, in the existing group management control system, in the case where boarding place indicators are installed, although the overall operating efficiency of the elevator will be somewhat reduced, in order not to cause discomfort to the user, it is necessary to prevent boarding. Operational control in pass and / or reverse operation. As such a technique, there is Japanese Laid-Open Patent Publication No. 2006-124075 (hereinafter referred to as Patent Document 1). [0004] However, in the existing gr...

Problems solved by technology

[0004] However, in the existing group management control system, if the operation control of preventing the boarding place from passing and / or reverse operation is performed, in the case of a large number of registrations at the boarding place, a plurality of elevators will respond to the latest unavailable call respectively. Responding to the call at the boarding place, so there will be a phenomenon in which multiple elevators travel in the same direction within a predetermined interval, which is the so-called blocked (sluggish) operation state

As a result, a large number of long waits for calls at boarding places will occur
