Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator group management control method for managing a plurality of elevator cars with different (irregular) service floors as a group.

[Conventional technology and problems]

Conventionally, in a group of elevators that service multiple floors, the floors that each car operates on are often the same, but for example, if there is a parking lot, management room, warehouse, etc. underground, a specific floor may be used. The service floors of each car may be different for various reasons, such as when only one car is in service on the basement floor.

Hereinafter, the floor where the service floors are different and only some cars can be used will be called the different level floor, and the floor where all the cars can be used will be called the common floor.As an example, as shown in Figure 2, the 6th floor including the basement floor There are 3 units A to C in the building.
A case will be described in which two elevators are in service, the first to fifth floors are common floors, and the first basement floor is a staggered floor.

In FIG. 2, for example, assume that a passenger on the third floor wants to go to the first basement floor and presses a landing call button (not shown) in the descending direction on the third floor. At this time, if B or C is assigned, there will be no problem, but
An inconvenience occurs when machine A is assigned.

In other words, at this time, passengers on the 3rd floor go to the 1st floor where they boarded the assigned aircraft A, register the hall call again on the 1st floor, and either transfer to another aircraft or
Either you can use the stairs from the floor to go to the first basement floor, or you can get through this without getting on Car A on the 3rd floor, and then register the hall call again on the 3rd floor and be assigned another car. This resulted in extremely inconvenient and poor service.

To solve this problem, for example, Japanese Patent Application Laid-Open No. 58-157679
As shown in the bulletin, when an elevator that does not service a different floor opens its door in response to a hall call, it will announce that it will not service a different floor, and will also press a push button for use of a different floor installed inside the car. By having a passenger press the button, the boarding hall call for the transfer floor is automatically registered.

However, even in this case, there are problems such as passengers having to change elevators to go to a single destination floor, and a push button for different floors having to be added to the control panel inside the car. It was hot.

[Means for solving problems]

The present invention has been made to solve the above problems, and when a hall call for a common floor is registered, the most suitable elevator is selected from a plurality of elevators and assigned to the hall call, and the assignment is When the landing is notified by a display device, etc., and the landing call button for the floor is then operated, the most suitable elevator is selected from among the plurality of elevators that can be used for the different floors. , is characterized in that it is assigned to that hall call.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a flowchart showing the procedure of the portion of the elevator group management control program related to the present invention, which starts with an interrupt process when a hall call button on a common floor is operated.

As in the case described above, each procedure in FIG. 1 will be described below when a passenger on the third floor in FIG. 2 registers a descending hall call for the third floor in order to go to the first basement floor.

When a passenger on the third floor operates the descending hall call button, the descending hall call is registered and the program shown in FIG. 1 starts.

First, it is determined whether the hall call has already been allocated (step S11), and if it has not been allocated yet, the most suitable car from among all car numbers (cars A to C in this case) is selected by normal allocation calculation. is selected (step S12). Assuming that Car A has been assigned based on the evaluation of waiting time, etc., this will be announced to passengers on the third floor using indicator lights (step S13), and at the same time,
A monitoring timer is started (step S14) and measurement of elapsed time after the allocation forecast is started. After that, the program will proceed to return, so this program ends for now, and if the passengers on the 3rd floor do nothing, the assignment will not change, and the A machine will respond to the 3rd floor and stop.

However, when the allocation forecast is made, it becomes clear that the passengers on the 3rd floor have been allocated to Car A, which cannot go to the 1st basement floor, so if they are dissatisfied with this allocation, they can press the boarding call button again in the descending direction. By operating , the program shown in FIG. 1 starts again.

In addition, at this time, there should be some kind of constant display in advance at the landing, or voice guidance, that Unit A cannot be placed in service on the first basement floor, and that if the assignment is inappropriate, the landing call button will have to be operated again. It is desirable to provide guidance only when necessary. However, if the number of passengers using the different floors is limited to a limited number of passengers, such display guidance is not necessarily necessary.

When the hall call button is operated again and the program shown in FIG. 1 is restarted, this time the hall call has already been assigned, so the process proceeds from step S11 to S15. In step S15, it is determined whether the assignment has already been changed, and if the assignment has already been changed to an elevator that can be used on different floors, there is no need to make any further changes and the process proceeds to return, but if not, the procedure Proceed to S16. In step S16, if there is no different floor in front of the hall call, there is no need to change the assignment, so the process goes to return, but if there is a different floor in front of the hall call, the process goes to step S17. In step S17, it is determined whether the allocation forecast has already been made. If the allocation forecast has not yet been made, passengers waiting at the landing do not know which car will respond, and therefore it is assumed that the reason why the landing call button was pressed again is for a reason other than the desire to change the allocation. Therefore, in that case, there is no need to change the allocation and the process proceeds to return, but if the allocation has already been predicted, the process proceeds to step S18. This procedure S
In step S18, it is determined whether the timer activated in step S14 is within a predetermined time limit. If this was within the predetermined time limit, there is a high possibility that the waiting passengers who saw the allocation forecast were dissatisfied with the allocation and operated the hall call button again, but if the button was operated beyond the predetermined time limit, a different For example, there is a high possibility that the operation was repeated because a later passenger pressed the hall call button without knowing that the hall call was already registered, so in such a case, the assignment may be changed. This is because there is no need to do this.

However, this monitoring timer is not necessarily necessary since a later passenger may become dissatisfied with the initial allocation and wish to change the allocation after a predetermined time limit.

If the timer is within the predetermined time limit, the process proceeds from step S18 to S19, and this time, excluding the elevator that cannot service different floors, that is, the elevator No. A, the most suitable elevator is selected and assigned from the remaining No. B and C elevators. Assuming that machine B is currently selected, the allocation forecast is changed from machine A to machine B (step S20),
Exit this program. Even if the hall call button is operated again after that, it will take step S.
Since the process proceeds from 11 to return via S15, no further assignment changes are made, and therefore, the B-car responds to the landing call for the 3rd floor descending direction, allowing passengers on the 3rd floor to go to the 1st basement floor without changing trains. .

In the above description, the case where the stepped floor is the lowest floor is explained, but it goes without saying that the present invention can be similarly applied even when the intermediate floor or the top floor is the stepped floor.

In addition, in the above embodiment, when the hall call button is operated again, the assignment is changed, but there is not always one person waiting at the hall, and if the assignment is changed, the elevator that was initially assigned will have a lower waiting time. There is a high possibility that the elevator will be changed to a longer elevator.
If you change the allocation when there are a mix of customers going to different floors and customers going to the common floor, the service may actually get worse for the customers going to the common floor, so change the allocation. Instead, when the hall call button is operated again, the initial assignment may be left as is and an elevator that can go to a different floor may be additionally assigned.

〔Effect of the invention〕

According to the present invention, even if the desired elevator is not allocated, an elevator that can reliably operate the different floor can be allocated simply by re-operating the hall call button, and the passenger can directly go to the different floor without changing trains. can go.

Moreover, there is no need to install new push buttons at each landing or in the car, and this can be done by simply changing the program, making it extremely economical and easy to apply not only to new construction sites but also to existing construction sites. be able to.
