Problems solved by technology

In such a case, if the elevator hall calls in the upward direction on the 4th and 5th floors that have been registered in car A are assigned to other cars, the 7th floor can be reached at the fastest. be the subject of an assignment change
[0007] In addition, as another problem, in the above-mentioned Patent Document 1, since the impact of the allocation change on the calls of other elevator halls is not considered, when the allocation is changed, new long-term waiting may occur on other floors.

no. 1 Embodiment

[0023] figure 1 It is a block diagram showing the configuration of the elevator group supervisory control device according to the first embodiment of the present invention.

[0024] The group management control device of the elevator in the present embodiment includes: a group management control unit 11 that uniformly controls a plurality of elevators; a single control unit 12a, 12b, 12c that controls the operation of each elevator under the group management control unit 11. ... The group management control unit 11, the individual control units 12a, 12b, 12c... are respectively realized by computers.

[0025] In addition, each elevator is also referred to as a "car" in units of cars (riding cars). Hereinafter, for convenience of explanation, it is assumed that three elevators are called elevators A, B, and C, respectively.

[0026] The individual control units 12a, 12b, and 12c perform control related to the operation of the cars 13a, 13b, and 13c of the A-number machine, B...

no. 2 Embodiment

[0060] Next, a second embodiment of the present invention will be described.

[0061] In the above-mentioned first embodiment, the long-time-wait rescue car is selected on the condition that the allocation change of the elevator hall call can arrive at the floor where the long-time wait occurs more than a predetermined time earlier than the number machine, and the allocation change does not cause a new long-time wait. alternate. In the second embodiment, it is characterized in that the candidate for the long-time-wait rescue aircraft is selected on the condition that the predicted load at the time of long-time wait for the response of the floor is below a certain value.

[0062] Figure 5 It is a block diagram showing the configuration of a group supervisory control device for elevators according to a second embodiment of the present invention. in addition, Figure 5 , and the above-mentioned first embodiment in the figure 1 Parts having the same configuration are attached...

no. 3 Embodiment

[0086] Next, a third embodiment of the present invention will be described.

[0087] In the third embodiment, it is characterized in that the candidate for the rescue call is selected on the condition that the number of people waiting on the floor where the long wait occurs at the time of response increases.

[0088] Figure 7 It is a block diagram showing the configuration of a group supervisory control device for elevators according to a third embodiment of the present invention. in addition, Figure 7 , and the above-mentioned first embodiment in the figure 1 Parts having the same configuration are attached with the same symbols, and their descriptions are omitted.

[0089] In the third embodiment, the group supervisory control unit 11 includes a load prediction unit 26 and a waiting number prediction unit 27 . Similar to the above-mentioned second embodiment, the load predicting unit 26 predicts the load when the car selected as the candidate for the long-waiting rescu...

Abstract

The invention provides a group management control device of an elevator. When a long-time wait sensing part (23) detects the long-time wait, an arriving time prediction part (22) predicts the time of a distributed number machine called by an elevator hall arriving at the long-time wait generation floor and the arriving time of other number machine changing the registered elevator hall to response to the long-time wait generation floor. A rescue number machine selection part 924) retrieves the number machines with arriving time earlier than the distributed number machine by a certain time and selects the number machine with shortest arriving time as the long-time wait rescue number machine. A rescue operation part (25) changes the elevator hall call distribution registered between the floors to the long-time wait generation floor in the elevator hall call distributed with the rescue number machine, into other number machine and changes the elevator hall call distribution of the long-time wait generation floor to the rescue number machine to perform the rescue operation.

Description

technical field [0001] Embodiments of the present invention relate to an elevator group management control device for collectively controlling a plurality of car elevators, and particularly to a group management control device for elevators performing rescue operation when a long waiting time occurs on a certain floor. Background technique [0002] In a group management system that controls elevators of multiple cars, in order to equalize the waiting time of each floor and shorten the unresponsive time, it is necessary to efficiently distribute the elevator hall calls of each floor to the elevators of each car. [0003] However, in practice, after the allocation of elevator hall calls, arrival is delayed due to registration of new elevator hall calls, car calls, etc., resulting in so-called "long waiting". "Long waiting time" refers to a state in which a certain period of time (for example, 60 seconds) or more has elapsed since the unresponsive time from the car to which the...
