Abstract

PURPOSE:To facilitate the riding of a wheelchair user by taking the statistics of the generated information of wheelchair leased calls so as to prepare necessary control information, placing a wheelchair cage in a standing-by position on an expected floor upon the generation of a wheelchair leased call and blocking another-hall call assignment to this cage for the wheelchair. CONSTITUTION:The statistics of the registered information of wheelchair leased calls from a registration device 1B are collected at a learning means 4 so as to prepare necessary control information. When the continuation of the registration of the wheelchair leased calls at a specific floor within the specified time every day or on a specific day of the week is recognized from the output of this learning means 4, an operation control means 3, upon the generation of the wheelchair leased call, places a cage for a wheelchair in a standing-by position on the expected floor and blocks another hall call assignment to this wheelchair cage. As a result, the probability of a wheelchair user riding immediately upon his arrival at the hall is heightened, thereby facilitating the use of the cage for the wheelchair.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for group management of a plurality of cars including wheelchair cars.

[Prior Art] In recent years, elevator group control devices have become capable of processing large amounts of information and performing sophisticated control through the use of microcomputers (hereinafter referred to as microcomputers). - is an indispensable means of vertical transportation within a building, and its users are made up of a wide range of 11 people, from the elderly to children and the physically handicapped. Therefore, for the convenience of wheelchair users, many elevators are now equipped with call registration devices specifically for wheelchair users. A wheelchair user can use the elevator easily and safely by operating this wheelchair-specific call registration device.

[Problem to be solved by the invention] In the conventional elevator group control device as described above, -
Cars that can accommodate wheelchairs (hereinafter referred to as wheelchair-accessible cars) are placed in the baskets that are managed as a group. If a user registers a wheelchair-only call, there is a problem in that the user has to wait at the boarding station until the wheelchair basket arrives.

This invention was made to solve the above-mentioned problems, and it is an object of the present invention to provide an elevator group management device that allows wheelchair users to easily use a wheelchair car.

Another object of the present invention is to provide an elevator group management device that can alleviate the inconvenience of general users due to the convenience of wheelchair users in addition to the above-mentioned objects. .

[Means to solve the problem] An elevator group management device according to the present invention.

Information on the occurrence of wheelchair-only calls is compiled to create the necessary control information, and wheelchair baskets are placed on standby in advance on floors where wheelchair-only calls are expected to occur.

This wheelchair cage is designed to prevent other hall calls from being assigned.

Further, in the elevator group management device according to another invention of the present invention, in the above-mentioned elevator group control device, if a wheelchair-specific call is not registered even after a predetermined period of time has passed after the wheelchair car enters the standby operation, This allows other hall calls to be assigned to the wheelchair cage inside.

[Function] In this invention, the time when a wheelchair-only call is generated is learned, and a wheelchair car is placed in advance on the floor where a wheelchair-only call is expected to occur, so that a wheelchair user can arrive at the boarding area. There is a high probability that you will be able to get into a wheelchair basket immediately upon arrival.

Further, in another aspect of the present invention, even if the wheelchair basket waits for a predetermined period of time, if the wheelchair user does not use it, it can respond to calls from other halls, so that the wheelchair basket is not left idle. time is reduced.

6).

It is assumed that each car is group-managed using an allocation method in which each car is allocated to a registered hall call.

In Figure 2, (11) is created by the traffic statistics means (5) and is stored in the RAM of the traffic statistics means (5) (not shown).
With the wheelchair-specific call registration information stored in the wheelchair-specific call registration device (IB), the operation control means (3
) and consists of 1 byte x 7 = bytes of information.

WC-CALL-MONTH is the month of occurrence WC-C-A
LL-DAY is the day of occurrence WC-CALL-WEEK is the day of the week of occurrence WC-CALL-HOUR is the time of occurrence (hour) WC-CALL-MINUTE is the time of occurrence (
) WC-CALL-FLOOR represents the generation floor WC-C:ALL-UPD represents the generation direction.

In Fig. 3, (12) is the traffic volume statistical result created by the control information creation means (6) and stored in the RAM (not shown) of the control information creation means (6), indicating the past week. The numbers in Figure 0 represent the number of times wheelchair-only calls have been registered for each time period, divided into a predetermined number for each day from Monday to Sunday, for each floor.

For example, in the past week, there have been registrations for wheelchair-only calls on the first floor, once between 10:10 and 10:20 on Mondays, and twice between 10:20 and 10:30. . This value is weighted and added for each floor, each day of the week, and each time period, and is newly stored as a learning result. Although not shown in Figure 1, traffic volume statistical results (12)
is created for all floors and all time periods.

Next, the standby operation of the wheelchair corner of this embodiment will be explained with reference to FIG. Note that this program is stored in the memory (not shown) of the operation control means (3). Then, the command shown in FIG. 4 is issued from the driving control means (3) to the wheelchair car control device (2B) based on the traffic volume for one week compiled by the learning means (4). This program is executed, for example, before each time period starts.

In step (21), it is determined whether a wheelchair cage is currently waiting on any floor. If the car is on standby, it is determined in step (22) whether there is enough room in the number of cars in operation for the current traffic condition in the current time zone. As this judgment condition, for example, whether the waiting time at the landing is long or short is used, depending on the information stored in the learning means (4). When it is determined in step (22) that there is a surplus in the number of vehicles in operation.

In step (23), it is determined whether any candidate waiting floor for wheelchairs is set in the current time period. In addition.

The operation for setting the waiting candidate floor will be described later with reference to FIG. If it is determined in step (23) that a waiting candidate floor has been set, it is determined in step (24) whether or not the currently waiting wheelchair cage is on the waiting candidate floor.

If the wheelchair car is not on the candidate floor, the wheelchair car is moved to the waiting candidate floor in step (25), and the assignment of a general hall call to the waiting wheelchair car is prevented in step (26).

Next, the operation for setting the waiting candidate floor will be explained with reference to FIG. This setting operation is executed, for example, when performing statistical processing at the end of -week, and detects the registration frequency of regular wheelchair-only calls from the learning results.

First, in step (31), time period i is set, and in step (32)
), initialize each floor k to O. Step (3
In step 3), it is determined based on the learning results whether a wheelchair-only call is registered on the floor every day or on a specific day of the week. This determination may be made, for example, if a wheelchair-only call has always been registered on a floor at the same time on the same day of the week over the past few months, or if a wheelchair-only call has always been registered on a floor within a certain time range every day from Monday to Friday. It is based on the fact that it is registered. If it is determined in step (33) that the floor meets the criteria, it is determined in step (34) whether the priority of the floor is higher than other floors. Here, the priority is 1. For example, if regular registrations for wheelchair-only calls occur on multiple floors within the same time period, the floor with the most number of registrations may be selected, or a specific floor (e.g. This is the criterion when you want to give priority to the main floor. If the floor is determined to have a high priority in step (34), the floor is set as a standby candidate floor in time period i in step (35).

Note that if it is determined in step (33) that no wheelchair basket is registered, or if it is determined in step (34) that the priority of the floor is low, step (35) is not executed. , in step (36), it is determined whether all floors k have been completed.

If not completed, add 1 to floor k in step (387), return to step (33), and perform steps (33) to (3).
6) is repeated, and in step (37) it is determined whether all time periods i have been completed. If not, in step (39), 1 is added to time period i and the process returns to step (32). Repeat steps (32) to (37).

In addition, if a wheelchair-only call does not occur on this waiting floor even after a predetermined period of time has elapsed after entering the standby operation and preventing the allocation of general hall calls in step (26) in FIG. By allowing passengers to allocate calls on other floors, it is possible to prevent wheelchair baskets from being left unnecessarily idle and to prevent extended waiting times for general calls on other floors. .

[Effects of the Invention] As explained above, in this invention, the information on the occurrence of wheelchair-only calls is compiled to create necessary control information, and the wheelchair car is made to stand by in advance on the floor where the wheelchair-only call is expected to occur. Since other hall calls are prevented from being assigned to this wheelchair car, there is a high probability that the wheelchair user will be able to board the car immediately upon arriving at the hall, and the wheelchair car can be easily used.

In another aspect of the present invention, if a wheelchair-specific call is not registered even after a predetermined period of time has passed after the wheelchair car enters the standby operation, another hall call is assigned to the waiting wheelchair car. Since this is now allowed, the amount of time that wheelchair baskets are left unattended is shortened, which has the effect of alleviating the inconvenience for general users.
