Therefore, it is not necessary to divide the service floor by the old and new elevator groups, and it is possible to operate the elevator with good serviceability even during the renewal.

Now, a hardware configuration for performing the renewal method of the group control elevator according to this embodiment will be described.

FIG. 6 is a block diagram showing a hardware configuration for carrying out a method of controlling a group management elevator according to an embodiment of the present invention.

In the figure, 11 is a new group management device composed of a microcomputer, 11a is a CPU functioning as a central processing unit, 11b is a read-only memory ROM, and 11c is a readable / writable memory. RAM 11d is an interface (hereinafter referred to as I / F) for connection with the hall call registration device 13, and 11e is an interface (hereinafter referred to as I / F) for connection with the respective management devices 14a to 14c. 12 is a hall call button arranged at the elevator hall, and 13 is a hall call registration device. 14a to 14c are platform management devices that manage each elevator, 15a to 15c are drive devices that actually control the drive of the elevators, and 16a is an elevator car. 1
7a to 17c are transmission lines for transmitting information between the respective management devices 14a to 14c and the I / F 11e of the new group management device 11, 18 is an old group management device having substantially the same configuration as the new group management device 11, and 19 is It is a transmission line for transmitting information between the old group management device 18 and the new group management device 11.

In the group management elevator having the hardware of this configuration, all the hall calls are taken into the new group management device 11 via the hall call registration device 13 by operating the hall call button 12. Further, the elevator allocation signal from the new group management device 11 is transmitted to the respective management devices 14a to 14c via the transmission lines 17a to 17c. Each unit management device 1
4a to 14c send commands to the driving devices 15a to 15c,
The elevator car 16a is moved up and down. Further, the hall calls are distributed from the new group management device 11 to the old group management device 18 according to a predetermined program and transmitted via the transmission line 19. From the old group management device 18 to the new group management device 1
Similarly to 1, the elevator allocation signal is transmitted to each car management device (not shown) via a transmission line (not shown) connected to the old group management device 18.

The ROM 11b of the new group management device 11 stores a predetermined allocation program for hall calls.
This program is read by the CPU 11a at any time, and the elevator is assigned to the hall call.

This allocation program will be described with reference to FIG.

FIG. 7 is a flow chart showing an elevator allocation program in the step B of the control method for the group control elevator according to the embodiment of the present invention. It should be noted that this program is a program for allocating elevators to hall calls according to the ratio of old and new vehicles, and this program is the B process of the renewal method, that is, the first old group control system which is already installed in the same elevator group And the second elevator group controlled by the newly established new group management method are mixed.

In the figure, first, in step S1, the ratio of new and old elevators is determined. If the ratio of the number of old and new elevators is 0: 3, the process proceeds to step S2, and all generated hall calls are transmitted to the old group management side. When the ratio of the number of old and new elevators is 1: 1, the process proceeds to step S3, the generated hall calls are alternately transmitted to the old group management side, and step S3 is performed.
In step 4, the remaining hall calls are assigned to the new group manager. When the ratio of the number of old and new elevators is 1: 2, the process proceeds to step S5, where 2/3 of the generated hall calls are transmitted to the old group management side,
In step S6, the remaining 1/3 hall calls are assigned to the new group manager. When the ratio of the number of old and new elevators is 2 to 1, the process proceeds to step S7, 1/3 of the generated hall calls are transmitted to the old group management side, and the remaining 2/3 hall calls are managed in the new group in step S6. Assign to the side.

In this way, all hall calls are distributed to either the old group management side or the new group management side according to the number ratio of the new and old elevators. Then, the hall calls assigned to the old group management side are assigned to the first elevator group controlled by the old group management system by the old group management system. Further, the hall calls distributed to the new group management side are assigned to the second elevator group controlled by the new group management system by the new group management system. In addition, in FIG. 7, the case where the ratio of the number of old and new elevators is 0: 3, the case of 1: 1, the case of 1: 2, and the case of 2: 1 are explained, but these ratios are not necessarily required. Approximate values are used instead of strict judgment. Further, the hall calls may be assigned in accordance with the number ratio other than the above number ratio.

As described above, in the renewal method of the group control elevator of this embodiment, when the existing group control elevator is replaced with the new group control elevator, it is controlled by the existing old group control method for the same elevator group. When the first elevator group and the second elevator group controlled by the newly established new group management method are mixed, all hall calls are taken in by the new group management side, and some hall calls are old and new. According to the ratio of the number of vehicles to the old group management side, the second group of elevators is managed and controlled in the new group, and the first group of elevators is also managed in the old group.

Therefore, with respect to the new and old elevator groups that are operating under different group management methods, all the hall calls have one group management and the new group management side or the old group depending on the number ratio of the old and new elevators. It is distributed to one of the management side, each hall call on the old group management side is assigned to the old elevator group and is controlled by the old group, and each hall call on the new group management side is assigned to the new elevator group and is controlled by the new group. Since it is controlled, the elevator group on the new group management side and the elevator group on the old group management side do not double stop on the same floor as in the past, and the elevator operation is a dumpling operation with each floor stopped. Therefore, the waiting time on each floor is short and the service for elevator users is improved. In addition, it is not necessary to divide the elevator group on the new group management side and the elevator group on the old group management side into zones with fixed service floors, and there are different group management elevators on the landing floor and destination floor. Since it is not assigned, inter-floor traffic is convenient, elevators are easy to use, and driving efficiency is improved. As a result, even when both old and new group control elevators are mixed, it is possible to control the group control elevator with good serviceability and operating efficiency.

By the way, in the above embodiment, the condition for allocating the hall calls is described as the case where the number of hall calls is distributed according to the ratio of the number of old and new elevators, but the condition is not necessarily limited to this condition, and for example, waiting It is also possible to transmit to the old group management side only for the hall calls whose time is equal to or longer than a predetermined value, and use the waiting time as a condition.

[0035]

As described above, according to the control method of the group control elevator of the present invention, all the hall calls are taken in by the new group control side, and some of the hall calls are transmitted to the old group control side according to predetermined conditions. However, the first elevator group controlled by the existing old group management method is controlled by the old group, and the second elevator group controlled by the new new group management method is controlled by the new group, respectively. For new and old elevator groups operating under different group management methods, all hall calls are distributed to either the new group management side or the old group management side according to predetermined conditions with one group management, Each hall call on the old group management side is first
Of the new group management side, each hall call is assigned to the second group of elevators, and the new group management control is performed. Therefore, the elevator group of the new group management side and the old group management are controlled. The elevator group on the side does not double stop on the same floor, and it is also necessary to divide the elevator group on the new group management side and the elevator group on the old group management side into zones with fixed service floors. It is possible to renew a group-controlled elevator with good serviceability and operational efficiency.
