You will be assigned to a hall call that does not work. Hall calls that do not satisfy the conditions are assigned to the platform control panel 1 of the No. 1 car operating under the new group management control. Further, a hall call that satisfies the conditions is transmitted to the old group control panel 4 via the call transmission interface 8, and is assigned to the elevator of No. 3 car. The conditions for distributing hall calls at this time are, for example, distributing the number of hall calls based on the ratio of old and new cars, or
The condition is that only hall calls for which the waiting time is longer than a predetermined value are transmitted to the old group control panel 4.

[0021] In this D process, all the renewal work has been completed, and all the control panels of Units 1 to 3 are connected to the new group control panel 6, so each landing call is handled by the new group control panel 6. 6, and is assigned to elevators from No. 1 to No. 3 using the new group management method by the new group management panel 6.

As described above, the most distinctive feature of this embodiment is as described in the explanation of step B in FIG. 3 above.
When performing renewal work to replace the existing group control elevator with a new group control elevator, the elevator group of Unit 3, which is controlled by the old group control method using the existing old group control panel 4, and the newly installed new group control panel 6, When there are elevators of No. 1 controlled by the new group management method, all landing calls are taken in by the new group management side via the new button row 7 and the new group control board 6, and the new group management side and the old group It is to be distributed appropriately between the management side and the management side. Therefore, there is no need to divide service floors into new and old elevator groups, and elevators with good serviceability can be operated even during renewal.

[0023] Here, a description will be given of the hardware configuration on which the group management elevator renewal method of this embodiment is carried out.

FIG. 6 is a block diagram showing a hardware configuration for carrying out a group management elevator control method 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 that functions as a central processing unit, 11b is a ROM that is a read-only memory, and 11c is a readable and 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 each of the management devices 14a to 14c. 12 is a hall call button disposed in the elevator hall, and 13 is a hall call registration device. 14a to 14c are car management devices that manage each elevator, 15a to 15c are drive devices that actually control the driving 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 the old group management device having substantially the same configuration as the new group management device 11; 19 is the old group management device; This is a transmission line for transmitting information between the old group management device 18 and the new group management device 11.

In the group control elevator having the hardware of this configuration, all hall calls are taken into the new group control device 11 via the hall call registration device 13 by operating the hall call button 12. Further, the elevator assignment signal from the new group management device 11 is transmitted to each elevator management device 14a to 14c via transmission lines 17a to 17c. Each unit management device 1
4a to 14c send commands to drive devices 15a to 15c,
The elevator car 16a is moved up and down. Furthermore, 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
1, an elevator assignment 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 elevators are assigned to hall calls.

This allocation program will be explained using FIG. 7.

FIG. 7 is a flowchart showing an elevator assignment program in step B of a group management elevator control method according to an embodiment of the present invention. This program is a program that allocates elevators to hall calls based on the ratio of old and new units, and this program is used in step B of the renewal method, that is, the first elevator that is controlled by the old group management method that is installed in the same elevator group. This is executed when a second group of elevators and a second group of elevators controlled by the newly established new group management method coexist.

In the figure, first, in step S1, the ratio of the number of old and new elevators is determined. If the ratio of the number of old and new elevators is 0:3, the process advances to step S2, and all generated hall calls are transmitted to the old group management side. If the ratio of the number of old and new elevators is 1:1, the process advances to step S3, where the generated hall calls are alternately transmitted to the old group management side, and step S
In Step 4, the remaining landing calls are assigned to the new group management side. If 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, and the remaining 1/3 hall calls are transmitted to the new group management side in step S6. Assign to the side. If the ratio of the number of old and new elevators is 2:1, the process proceeds to step S7, where 1/3 of the generated hall calls are transmitted to the old group management side, and the remaining 2/3 hall calls are transmitted to the new group management side 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 depending on the ratio of the number of old and new elevators. Then, the hall calls distributed to the old group management side are assigned to the first elevator group controlled by the old group management method according to the old group management method. In addition, the hall calls assigned to the new group management side are assigned to the second elevator group controlled by the new group management method using the new group management method. In addition, in Figure 7, cases where the number ratio of old and new elevators are 0:3, 1:1, 1:2, and 2:1 are explained, but these number ratios do not necessarily apply. Rather than making a strict judgment, an approximate value is used. Further, hall calls may be allocated in accordance with a number ratio other than the above-mentioned number ratio.

As described above, in the renewal method of group control elevators of this embodiment, when replacing an existing group control elevator with a newly installed group control elevator, the same elevator group is controlled by the old group control method. When the first group of elevators and the second group of elevators controlled by the newly installed new group management system coexist, all hall calls are taken in by the new group management side, and some hall calls are transferred to the old and new elevators. is transmitted to the old group management side according to the ratio of the number of elevators, and the second elevator group is controlled by the new group management, and the first elevator group is controlled by the old group management.

Therefore, for the old and new elevator groups operating under different group management systems, all hall calls are handled by one group management, depending on the ratio of the number of old and new elevators, to the new group management side or the old group management system. Each hall call on the old group management side is assigned to the old elevator group and controlled by the old group, and each hall call on the new group management side is assigned to the new elevator group and controlled by the new group. As a result, unlike in the past, the elevator group on the new group management side and the elevator group on the old group management side do not make double stops at the same floor, and the elevator operation is like a dumpling operation that stops at each floor. Therefore, the waiting time at each floor is shortened, and the service for elevator users is improved. Furthermore, there is no need to divide the elevator group under the new group management side and the elevator group under the old group management side into zones with fixed service floors. Since there are no assignments, inter-floor transportation is convenient, elevators are easier to use, and operation efficiency is improved. As a result, even when both old and new group control elevators coexist, it is possible to control the group control elevators with good serviceability and operational efficiency.

By the way, in the above embodiment, the condition for distributing hall calls is explained as the case where the number of hall calls is distributed based on the ratio of the number of old and new elevators, but the condition is not necessarily limited to this condition. Only hall calls whose time is longer than a predetermined value may be transmitted to the old group management side, and the waiting time may be set as a condition.

[0035]

[Effects of the Invention] As explained above, in the control method for a group control elevator of the present invention, all hall calls are taken in by the new group control side, and some hall calls are transmitted to the old group control side according to predetermined conditions. The first elevator group, which is controlled by the existing old group management method, is controlled by the old group management, and the second elevator group, which is newly installed and controlled by the new group management method, is controlled by the new group management. For new and old elevator groups operating under different group management systems, all hall calls are distributed to either the new group management side or the old group management side according to predetermined conditions under one group management system. Each boarding area call on the old group management side is number 1.
At the same time, each landing call on the new group management side is assigned to the second elevator group and is controlled by the new group management, so that the elevator group on the new group management side and the old group management There is no need to divide the elevator group on the side management side and the elevator group on the old group management side into zones with fixed service floors. This makes it possible to renew group control elevators with good serviceability and operational efficiency.
