JPH05147835A - Elevator stop calling register for disabled people - Google Patents

Abstract

PURPOSE:To prevent degradation of service due to erronous registration for an elevator group in which an elevator for general passenger is used also as an elevator for disabled people, by judging whether a call from disabled people is really from a disabled person or not, on the elevator side. CONSTITUTION:When a call from a call button for elevator stop for disabled people is registered, it is judged whether there is a wheelchair or not by a wheelchair detector 11 through an image recognition process based on image information collected by a television camera, and when a wheelchair exits, an elevator for disabled people is allotted to this call by an elevator controller 10. When a wheelchair does not exist, the call is cancelled by the elevator controller. Even when a call for elevator stop for disabled people is registered by a general passenger in form of his mischief, it is judged whether the call is really from a disabled person on the elevator side or not, based on which the call is validated or cancelled, and degradation in operational service due to erronous registration, can be thus prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator which is commonly used by a passenger for a passenger and an elevator for a physically handicapped person in a group of a plurality of elevators, and efficient elevator call assignment for both of them. Regarding

[0002]

2. Description of the Related Art Elevators for general passengers serviced by a plurality of elevators are considered to be used by people with physical disabilities, and some elevators are often used as elevators for people with physical disabilities. As a guideline, JEAS-506B, "Standard specifications of wheelchair-equipped elevator" has been established, and according to it, (1) It is obligatory to provide a dedicated landing call button for people with disabilities. This is because the elevators for people with disabilities are only compatible with specific units, so people with disabilities must always board the elevators for people with disabilities at the landing, while the elevators must be equipped with elevators for people with disabilities. It has to be assigned to the call for the dedicated landing button.

However, the hall call button for persons with physical disabilities can be pushed even by a person who is not physically handicapped. Therefore, it is often operated when a general passenger is irritated. Even after servicing the floor, an elevator for people with disabilities must be assigned to this floor without fail, which significantly impairs overall driving efficiency.

[0004]

In order to solve this problem, Japanese Laid-Open Patent Publication No. 54-56864 describes a method of providing an up and down wheelchair detection device on the landing floor to distinguish it from a general call. However, this method had a problem that disabled people had to go to the up and down positions themselves. Further, since the wheelchair detection device for all floors must be kept valid at all times, there is a problem in terms of energy saving.

[0005]

In order to solve the above problems, the present invention installs a television camera near the entrance of an elevator for persons with disabilities, detects a wheelchair by a known image recognition processing technique, and calls for persons with disabilities. It was made possible to recognize whether the operation of the button was caused by a disabled person.

When the elevator control device determines that the call registration by the call button for the disabled is not a call by the disabled, the call for the disabled is canceled.

Further, since this wheelchair detection device is adapted to be able to detect the call button for persons with disabilities after the operation, the wheelchair detection device installed on each floor does not need to be always valid.

[0008]

[Operation] The TV cameras installed on each floor operate after the hall call button for people with disabilities is pressed. Then, if the image recognition processing device installed in the elevator machine room detects a wheelchair, this call is judged by the elevator control device to be a call for persons with disabilities, and the elevator machine that is adapted for persons with disabilities is assigned to this call. Put on. If the wheelchair is not detected for a certain period of time, the elevator control unit determines that the call of the hall call button for disabled persons is erroneously registered and cancels the call.

On the other hand, an image input device including this television camera is required on each floor, but since the hall call button for persons with disabilities is made to operate after the operation, it is not necessary to keep it valid all the time, and it is possible to save a great deal of energy. Energy can be expected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 shows a hall entrance / exit of an elevator for persons with disabilities, and 1 is a hall call button for general passengers, and 2 is a hall call button exclusively for persons with disabilities. Reference numeral 3 indicates an entrance / exit of an elevator for people with disabilities, and 5 indicates a television camera installed on a ceiling 4 of the entrance / exit.

FIG. 2 shows a block diagram of the present invention. The elevator control device 10 that has received the call for the handicapped person using the hall call button 2 exclusively for the handicapped person enables the power sources of the wheelchair detection device 11 and the TV camera 12, and the image input 12 by the TV camera 5 is installed in the machine room of the elevator. The image is sent to the wheelchair detection device 11 by the image recognition processing, and it is determined whether or not there is a wheelchair on the floor where the call for the wheelchair is received. That information is the elevator control 10
If there is a wheelchair, the elevator for the disabled is assigned to the floor, and if the wheelchair is not detected, the elevator controller 10 cancels the call for the disabled.
Returning to normal operation Hereinafter, this flowchart is shown in FIG.

That is, when registration (step 22) is performed by the hall call button 2 for persons with disabilities during normal operation (step 21), the elevator control device 10 turns on the television camera of the corresponding floor (23), This image information is sent to the wheelchair detection device 11. If the wheelchair detection device 11 does not detect the wheelchair, the hall call registration for the disabled is canceled (step 25) and the normal operation is resumed. However, when the wheelchair is detected, the elevator control device 10 causes the disabled call button to be pressed. Registration as a valid call (step 24,
26) Allocate this call to a disabled elevator.

When the service of the elevator for persons with disabilities ends (steps 27 and 28), the elevator returns to normal operation.

[0015]

As described above, according to the present invention, the call registration by the hall call button for the disabled, which can be operated by anyone, is performed by the elevator side to judge whether or not the call is due to the disabled person, and the call registration is performed. It is possible to prevent erroneous registration due to annoying mischief and the like, and prevent a decrease in elevator service efficiency due to the assignment of an elevator for persons with disabilities due to erroneous registration. Further, since the TV camera and the wheelchair detection device are made effective after the call registration for the handicapped person, it is not necessary to be made effective all the time, and an energy saving effect can be expected.
