Abstract

PURPOSE: To permit the direct traveling of an elevator to a double-level floor without changing the elevator even in the case where a desirable elevator is not assigned for traveling by selecting the optimal elevator capable of traveling to the double-level floor only with the re-operation of a landing call button, and assigning the elevator to the landing call. CONSTITUTION: When a landing call is registered, the optimal elevator is selected among plural elevators (a process S12), the selected elevator is assigned to the landing call, and while this assignment is informed to the landing with a display device (a process S13). Thereafter, when a landing call button of this floor is operated, the optimal elevator capable of traveling to a double-level floor is selected among the plural elevators (a process S20), and assigned to the landing call. As a result, a passenger can directly go to the double-level floor without changing the elevator.

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, a floor with different service floors where only one group of cars can be used will be called a different level floor, and a floor where all cars can be used will be called a common floor.-As an example, as shown in Figure 2, a floor with 6 floors including a basement floor will be called a common floor. A case will be explained in which three elevators A to C are in service in a building, the 1st to 5th floors are common floors, and the 1st basement floor is a different 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 of the third floor. At this time, there will be no problem if the B or C car is allocated, but if the A car is allocated, an inconvenience will occur.

In other words, at this time, passengers on the 3rd floor board the assigned car A and go to the 1st floor, register the hall call again on the 1st floor and transfer to another car, or use the stairs from the 1st floor to go to the 1st basement floor. The only option is to either go to the 3rd floor without getting on the A car, register the hall call again on the 3rd floor, and wait for another car to be assigned. It was inconvenient and the service was poor.

In order to solve this problem, for example, Japanese Patent Application Laid-Open No. 58-157679
As indicated in the publication, when an elevator that does not service different floors opens its doors in response to a hall call,
By announcing that there will be no service on the different floors and having the passenger press a push button for using the different floors provided inside the car, 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. there were.

[Means for solving problems]

The present invention has been made to solve the above problems,
When a hall call is registered, the most suitable elevator is selected from among multiple elevators and assigned to that hall call, and the assignment is announced to the hall using a display device, etc., and then the hall call button for the floor is operated. Then, the most suitable elevator is selected from among the plurality of elevators that can be used for different floors, and is assigned to that hall call.

〔Example〕

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

Figure 1 shows the elevator group management control program.
This is a flowchart showing the procedure of the part related to the present invention, which starts with an interrupt process when the hall call button 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 assigned or not (step Sl'l). If the hall call has not been assigned yet, the most suitable one is selected from among all the cars (cars A to C in this case) by normal allocation calculation. A machine number is selected (step 512). Assuming that machine A is now assigned based on the evaluation of waiting time, etc., this is
At the same time as giving a forecast to passengers on the floor using indicator lights (step 513), a monitoring timer is activated (step 514) to start measuring the elapsed time after the allocation forecast. 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 group of people, 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 311 to S15.

In step S15, it is determined whether the allocation has already been changed,
If the assignment has already been changed to an elevator that can be used for different floors, there is no need to make any further changes and the process proceeds to return; otherwise, the process proceeds to step 316. In step 316, 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 317. In step 317, it is determined whether the allocation forecast has already been made. If the allocation forecast had not yet been made, passengers waiting at the landing would not know which car would answer, and the reason why the landing call button was pressed again was due to a reason other than the request for a change in allocation. In that case, there is no need to change the allocation and the process goes to return, but if the allocation has already been predicted, the process goes to step 318. Determine whether it exists or not. If this was within the specified time limit, there is a strong possibility that the waiting passengers who saw the allocation forecast were dissatisfied with the allocation and operated the hall call button again.
If the button is operated beyond the specified time limit, it is possible that the button was operated again for another reason, such as a passenger who arrived later pressed the hall call button without knowing that the hall call was already registered. This is because there is no need to change the allocation in such a case since the nature of the allocation is large.

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

If the timer is within the predetermined time limit, the process proceeds from steps 318 to 319, 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 elevators B and C. Assuming that car No. B is selected now, the allocation forecast is changed from car No. A to car B, step 520), and this program is terminated. Even if the hall call button is operated again after that, the process will proceed from step Sll to return via step 315, so no further assignment changes will be made, and therefore, Car B will respond to the hall call in the direction of descending to the third floor. Passengers on the third floor can go to the first basement floor without changing trains.

In the above explanation, the case where the floor with different steps is the lowest floor is explained, but it goes without saying that the present invention can be similarly applied even if the middle floor or the top floor is the different 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. Since there is a high possibility that customers will be changed to an elevator that takes a longer time, if the assignment is changed when there are a mix of customers going to different floors and customers going to the common floor, the service will be worse for the customers going to the common floor. (This may happen, so instead of changing the assignment, when the hall call button is operated again, the initial assignment may be left as is and an additional elevator that can go to a different floor may be assigned. - [Effects of the Invention] According to the present invention, even if the desired elevator is not allocated, an elevator that can reliably operate a different floor can be allocated simply by re-operating the hall call button, and passengers can always change trains. You can go directly to a different floor without having to worry about it.

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.
