Problems solved by technology

[0009] That is, in the method (a) described first, since the operation and non-operation of the power-saving operation are judged only based on the average unresponsive time, even if there are few passengers who are idle During the time period, there are still cases where the power saving operation cannot be started
[0010] In addition, in method (b), since the allocation method of calls at the elevator place is changed for each operation mode of upward traffic flow and downward traffic flow, the amount of traffic flow in the upward direction is different from that of traffic flow in the downward direction. In the case of balanced traffic flow, the same judgment as the normal traffic flow cannot be obtained to save power
[0011] In addition, in the method (c), even in normal operation, the allocation evaluation of power saving is still carried out, thus, the user must usually accept a long waiting time before responding to the call of the elevator to some extent, Increased average wait time and compromised user convenience

no. 1 Embodiment approach

[0030] figure 1 It is a schematic configuration diagram showing an elevator system incorporating the group supervisory control device according to the first embodiment of the present invention.

[0031] The elevator system according to the first embodiment is mainly composed of a plurality of elevators 1a, 1b, and 1c and one group supervisory control device 2 . In each elevator 1a, 1b, 1c, the main wire rope is suspended on a reel connected to the shaft of the electric motor 4 assembled inside the driving part 3, which is installed in the lifting and lowering of the building not shown in the figure. the top of the pathway. A car 5 on which passengers ride is suspended from one end of the main cable, and a counterweight 6 is suspended from the other end of the main cable.

[0032] Inside the car 5, a car call registration device 7 for specifying a destination floor of the passenger riding on the car 5 is installed. The "car call" designating the destination floor specified b...

no. 2 Embodiment approach

[0070] Figure 7 It is a schematic configuration diagram of an elevator system incorporating a group supervisory control device according to a second embodiment of the present invention. for with figure 1 The same parts of the elevator system according to the first embodiment shown are denoted by the same reference numerals, and detailed description of overlapping parts will be omitted.

[0071] Inside the group supervisory control device 2a of the elevator system of the second embodiment, a power consumption data memory 27 is provided instead of the operation data memory 14 of the first embodiment, and a power consumption data memory 27 is provided instead of the current operation data detection unit 17. Current power consumption data memory 28 .

[0072] Inside the power consumption data memory 27, such as Figure 8 As shown, the past power consumption data consumed by the motors 4 of all the elevators 1a, 1b, and 1c generated in each period of a fixed period unit such as...

Abstract

The present invention relates to a group management control device for a elevator system. In an elevator system having a plurality of elevators (1a-1c) and a control part, when generating a new elevator call, according to a predicted value obtained by the operation data of a time interval of a bygone same time interval and a current value of the operation data of a current time, when the two values are all over a prescribed value, the elevator is running in a electricity-saving mode. in addition, when the electricity-saving mode is running, each elevator is divided into a power set (23) and a regeneration set (24). in addition, each response index (E1, E2) corresponding to the elevator call of each set, when the difference between the E1 and the E2 is in a certain limitation, the elevator call will be distributed to the elevator of the regeneration set. Thus, it is only capable of operating the elevator in the electricity-saving mode if necessary in deed with a minimum inhibition infection for user convenience.

Description

technical field [0001] The present invention relates to an elevator system composed of a plurality of elevators installed in a building and a control device for controlling the operation of the plurality of elevators, and particularly relates to distributing calls to elevators generated on each floor of a building to a plurality of elevators The group control control device of the elevator system of the best one elevator among elevators. Background technique [0002] In an elevator system in which a plurality of elevators are installed in one building like a large-scale building, the utilization status of each elevator is not constant in each time zone. For example, if one day is considered as a unit, the elevator is not evenly used 24 hours a day. The utilization rate of the morning attendance period, the noon meal period, and the evening off-duty period is high, but the utilization rate of other periods is high. Low. Also, even if viewed on a weekly basis, the utilizatio...
