Description

Description: [Industrial field of application] The present invention relates to an apparatus for operating and managing a plurality of groups of elevators, each of which is group-managed.

[Prior Art] In a group management elevator, a common hall button is installed for multiple cars, and when a hall call is registered with this hall button, one of the cars in the same group is assigned to it. I am trying to make the hall call respond. In some cases, the group-controlled elevators have a common hall and there are a plurality of groups. In this case, when the hall call for the first group is registered, this signal is also transmitted to the second group and both groups The cooperative driving of is done. At this time, the two groups operate so that the cars in the respective groups are assigned to the hall calls, so that two cars may arrive at the same floor. In order to avoid this, various proposals have been made.

For example, in Japanese Unexamined Patent Publication No. 62-215482, a lighting signal of a hall call registration light (built into a hall button) and a call registration prohibition signal are transmitted from the first group to the second group, and the same hall call has two cars. The ones that prevent the table from responding are shown.

Further, Japanese Patent Laid-Open No. 64-22770 discloses a first group and a second group.
It is shown that the cars of both groups are assigned with common hall calls for the groups to prevent the cars that arrive earlier from canceling the hall calls and stopping two cars.

In addition, in Japanese Patent Application No. 1-324277, when a call for a specific floor (car call) is registered in the second group of cars,
It is shown that the group calls are released so that the cars in the first group do not respond.

[Problems to be Solved by the Invention] In the elevator group management device configured as described above, when a car registration prohibition signal is transmitted, a car that arrives early releases a hall call, or a car call occurs, Since the call is canceled to prevent two cars from responding to the same hall call, there are the following problems.

That is, in the ones, only the cars in the group in which the hall buttons are always pressed are assigned. In addition, can not be adopted in the group-controlled elevator of the instant warning light system. The instant forecast light system is a system for calculating which car will come when a landing button is pressed, and immediately turning on and guiding the forecast light at the landing of the car. When this system is adopted, if a plurality of forecast lights are turned on, or if a landing call is canceled midway, the forecast lights are turned off at the same time, or the waste car is driven.

The present invention has been made to solve the above problems, and it is possible to prevent a plurality of cars from stopping at the same landing and to allocate the car allocation so that the loads of both groups are balanced. It is an object to provide an elevator group management device.

[Means for Solving the Problem] The elevator group management device according to the first aspect of the present invention communicates by transmitting and receiving two signals between both groups of the group management elevator, and by combining these two signals, the hall Calls are shared by both groups, and four types of patterns are set regarding which group of cars are assigned to hall calls.

Also, in the elevator group management system according to the second aspect of the present invention, in the first aspect of the invention, when the cars of the first group are approaching the hall for car calls, two signals are output in a predetermined pattern. Even if the hall call button of the second group is operated after being transmitted to the second group, this hall call is not assigned to the cars of the second group and is returned to the first group in a predetermined pattern.

Also, in the elevator group management system according to the third aspect of the present invention, in the first aspect of the present invention, when the hall call is registered in the first group, the predicted waiting time of the hall call becomes a predetermined value or more. When it is determined that the two signals are transmitted, the two signals are transmitted to the second group in a predetermined pattern.

[Operation] In the first aspect of the present invention, two signals are transmitted and received between the two groups, and four types of patterns for sharing and allocating hall calls are set by the combination of these two signals. The distribution of calls to both groups can be selected according to patterns.

Further, in the second aspect of the present invention, when the car of the first group is approaching by a car call, even if the hall button of the second group is operated, this car hall call is directed to the car of the second group. Since the reply is made to the first group without allocating, the car registered with the car call is allocated to this hall call.

Further, in the third aspect of the present invention, when the hall call is registered in the first group, if it is determined that the predicted waiting time becomes a predetermined value or more, the hall call is returned to the second group. Therefore, the car of the second group is assigned to this hall call.

[Embodiment] FIGS. 1 and 2 are views showing an embodiment of the present invention.
FIG. 1 is an overall configuration diagram, and FIG. 2 is a flowchart showing the operation.

In FIG. 1, (1) is a group management device of a first group composed of a microcomputer (hereinafter referred to as a microcomputer), which is a CPU
(1A), ROM (1B), RAM (1C) and interface (1
D) (1E), the interface (1D) is connected to the call button (2A) and the hall call registration light (2B) of the hall button (shown for one specific hall) (2), and 2 sent to a group management device (not shown) of 2 groups
The signal (3a) (consisting of signals A and B) is output, and the two signals (3b) (consisting of signals C and D) transmitted from the group management device of the second group are input. The interface (1E) is connected to the platform control devices (4A) to (4C). (5A) ~
(5C) is a car whose operation is controlled by the platform controllers (4A) to (4C), respectively.

 The second group has the same configuration.

Next, the operation of this embodiment will be described with reference to FIG. The program of this flow chart is the ROM of the microcomputer
It is stored in (1B). Note that FIG. 2 shows the operation of the first group, and the second group reads the signals C and D of FIG. 2 into the signals A and B, and the signals A and B into the signals C and D. .

First, in step (10), the two signals C and D from the second group are discriminated. Now, if the two signals C and D from the second group do not come, the process proceeds to the process (0, 0), and the step (11)
Then, it is determined whether the call button (2A) of the landing button (2) of the first group has been pressed. If the call button (2A) is pressed here, the hall call registration light (2
B) is turned on, and in step (13), this hall call is temporarily assigned to one of the cars (5A) to (5C) in the first group. In step (14), it is determined whether the predicted waiting time of the hall call is equal to or longer than a predetermined value. Here, the first group of service baskets (5A)
When it is determined that the number of (5C) is reduced and the predicted waiting time is equal to or longer than the predetermined value, 2 signals A and B =
It outputs (1, 1) and sends it to the second group. This time second
It becomes the processing on the group side, and the 2 signals C and D in step (10) are 2
When the signals A and B are read, the process proceeds to the process (1, 1), the hall call registration light is turned on in the step (17), one car of the second group is allocated in the step (15), and the step is performed. At (16), two signals C and D = (1, 0) are output and transmitted to the first group. In the first group, the process proceeds from step (10) to step (23), and the lighting of the hall call registration light (2B) is maintained.

When it is determined in step (14) that the predicted waiting time of the hall call is at the end of the predetermined value, it is assigned to the second group of cars in step (15) and transmitted to the first group in step (16).

In this way, when the landing button (2) of the first group is pressed when the first group is overloaded, the cars of the second group can be assigned and the loads of both groups can be balanced. Is possible.

Next, when it is determined in step (11) that the first group landing button (2) is not pressed, it is determined in step (21) that there is a car arriving within a predetermined time by calling the car to the specific landing. Then, the process proceeds to step (22), and 2 signals A and B =
It outputs (0, 1) and sends it to the second group. In the second group, similarly to the above, the process proceeds from step (10) to processing (0, 1), it is determined in step (18) whether the landing button of the second group is pressed, and if it is pressed, At step (19), the hall call registration light is turned on, and at step (20), 2 signals C, D =
It outputs (1, 1) and transmits it to the first group. In the first group again, steps (10) → (17) → (15) → (16) are proceeded, and one of the cars (5A) to (5C) of the first group is assigned. Naturally, the car that is approaching will be selected by calling the car.

If the car of the second group is assigned at this time, the car with the car call of the first group will also arrive, so the forecast will be missed and another car will arrive first, or two cars will arrive first. The car will stop. In the above embodiment, such a problem can be prevented.

In the above embodiment, the specific landing was explained, but it is also possible to apply to all landings.

Further, the predetermined value of the estimated waiting time in step (14) in FIG. 2 may be set to a fixed value, or a changing value such as (average waiting time + 10 seconds) at that time may be used. . Further, when the value is equal to or more than the predetermined value in step (14), it is possible to easily assign the car of the own group and the car of the other group.

It should be noted that the step (21) in FIG. 2 can be easily implemented by including a car on the floor waiting for the door to close.

[Effects of the Invention] As described above, in the first invention of the present invention, two signals are transmitted and received between both groups of the group-controlled elevator, and the combination of these two signals makes it possible to share hall calls and assign hall calls. Since the pattern of seeds is set, the distribution of hall calls to both groups can be selected according to the pattern, it is possible to prevent multiple cars from stopping at the same hall and also to distribute the hall calls. There is an effect that the loads of both groups can be balanced.

Also, in the second aspect of the present invention, when the car of the first group is approaching by car call, even if the hall button of the second group is operated, this hall call is assigned to the car of the second group. Instead, since the car is replied to the first group, it is possible to reduce the allocation forecast failure due to the unpredicted car that is assigned the car with the above car call registered to this hall call and stops at the car call. There is an effect that can be.

Further, in the third aspect of the present invention, when the hall call is registered in the first group, if it is determined that the predicted waiting time becomes a predetermined value or more, the hall call is transmitted to the second group. Therefore, the car of the second group is assigned to this hall call, and there is an effect that the average waiting time and the maximum waiting time of both groups can be shortened.
