[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control device for a wheelchair elevator,
In particular, the present invention relates to a control device for a wheelchair elevator that restricts registration of unnecessary calls from a dedicated car call registration device.

[Conventional technology]

In addition to the call registration device used by general passengers, wheelchair-accessible elevators have a call registration device located at each floor's landing and in the car.

It is equipped with a dedicated hall call registration device and a dedicated car call registration device that are installed at a height that is easy for passengers using wheelchairs to operate. When the elevator services calls registered by these dedicated call registration devices, and when the elevator door is open for calls from general passengers, taking into account the convenience of wheelchair users when getting on and off. It is set longer than .

Therefore, even if a general passenger accidentally or mischievously operates the dedicated car call registration device, the elevator door will remain open for a long time, and the service performance of the elevator will deteriorate.

Therefore, as a means to solve the above problem, JP-A-59-1
The one shown in Japanese Patent No. 53771 has been proposed.

This method allows a new dedicated car call to be registered within a predetermined time after the elevator stops in response to a call from the dedicated hall call registration device.

[Problem that the invention seeks to solve]

However, with the conventional method described above, it is not possible to determine whether or not a wheelchair user has entered the elevator car. This made it possible to register elevators, which caused the problem of worsening the serviceability of elevators.

This invention was made to solve the above-mentioned problems, and even if an ordinary passenger accidentally or intentionally operates the special car call registration device for wheelchair users, it can be disabled. An object of the present invention is to provide a control device for a wheelchair elevator that eliminates deterioration of service performance of the elevator.

[Means for solving problems]

The control device for a wheelchair elevator according to the present invention includes a device for detecting when a wheelchair user enters the vehicle, and a dedicated hall call registration button for the elevator! Control means that enables a new call to be registered by a dedicated car call registration device only when the boarding detection device operates for a predetermined period of time after stopping in response to an IK call. It is.

[Effect]

In this invention, the control means determines whether the device for detecting entry of a wheelchair user has operated for a certain period of time after the elevator stopped in response to a dedicated hall call, and determines that the device has operated for a certain period of time. Registration of unnecessary car calls is restricted by allowing registration of new dedicated car calls only in certain cases.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows a circuit diagram of a control device for a wheelchair elevator according to the present invention, where l is a small computer for elevator control, and a central processing unit that manages and controls various calculations, internal devices of the computer, and external devices.

This is a normally open contact of the ATF photoelectric device for detecting when a wheelchair user enters the vehicle, and it closes when the wheelchair user enters the vehicle.One end of the normally open contact 6 is connected to the input device of the small computer 1. The other end is connected to the power supply line 7. /C is 1
Normally open contacts +nC and (n-/
) This is the normally open contact of the dedicated car call registration button on the nth floor and the n-1st floor, and the normally open contact of the dedicated car call registration button /C”n
One end of C is connected to the input device DA, and the other end is connected to the power supply line 7, respectively, and call signals generated by the closing of the normally open contacts /C to nC are taken into the input device DA.

Also, /H is the normally open contact of the dedicated hall call registration button for the first floor, n
H and (n-/)H are the normally open contacts of the dedicated hall call registration buttons for n5iJ and n-1 floors, and these normally open contacts/H-
One end of nH is connected to the above input device.

The other ends are respectively connected to the power supply line 7, and the call signal of each normally open contact /H=nH is taken into the input device DA.

Dedicated car call button lamps for /CLFi 1st floor* nCL and (n-/)CL are dedicated car call button lamps for the nth and n-1st floors, and one end of each of these lamps /CL to nCL is connected to the small computer l mentioned above. The other end is connected to the output device 3, and the other end is connected to the power supply line S. Also, /HL is a dedicated hall call button lamp for IN + nHL and (n-/)HL are all!
These are dedicated hall call button lamps for the J and n-1 floors, and one end of each of these lamps/HL-nHL is connected to the output device [116], and the other end is connected to the power supply line t.

Next, the operation of this embodiment configured as described above will be explained.

When an elevator user specifies a destination by pressing a dedicated car call button, the corresponding normally open contact 1, such as a normally open contact IC, closes, and the resulting call signal is input to the CPU through the input device. . The CPU executes calculations according to the processing program and sets an indicator light lighting signal corresponding to the 11th floor in the output device 3. As a result, the output device S
The circuit connecting the lamp/CL and the power line t becomes conductive and becomes 1.
The dedicated car call button lamp/CL for the floor lights up.

Also, if a hall call is generated by pressing the dedicated hall call button, the normally open contact /H-nH of the pressed hall call button.

For example, when nH is closed, the call signal is input to the CPU through the input device, and the call signal is input to the CPU by the CPU.
A lamp lighting signal corresponding to the H floor is set in the output device 3, thereby lighting the dedicated hall call button lamp nHL for the nH floor.

Although a detailed explanation will be omitted, the small computer 1 issues an operation command to the floor corresponding to the registered call to the elevator operating circuit, and operates the elevator to that floor for service. At the same time, the small computer l executes a process for restricting dedicated car call registration.

FIG. 2 shows a processing flowchart for restricting the above-mentioned dedicated car call registration, and the processing is incorporated into a part of the control program executed by the small computer l.

That is, when the flow shown in FIG. 2 starts, first, in step S/, a dedicated hall call signal is read through the input device DA. And the next step S-
Now, set the unregistered private hall call in the data table of the storage device 3.

Step S3 is to check whether the elevator is stopped or not; if one elevator is running, step S3 is performed.
When it is determined that the system is stopped, step S
Move to Dahe.

In step SII, the dedicated hall call registration state set in step S is searched, and it is determined whether or not the response to the dedicated hall call has stopped. Here, if the stop occurs in response to a 1-dedicated hall call, the process moves to step SjK; otherwise, the process moves to step SjK.

Generally, a small computer 1 for controlling an elevator is equipped with an internal timer, although a detailed explanation thereof will be omitted. Therefore, in the step S3 above, the photoelectric device for detecting the entry of a wheelchair user is activated, and the information that the normally open contacts 6 are closed is read into the CPU through the input device. The closing time of the contact base is calculated, and it is determined whether the photoelectric device for detecting entry of a wheelchair user operates for a certain period of time (for example, 3 seconds) and whether or not it is correct. When it is determined that the operation has been performed for a certain period of time, the process advances to step S4. However, if the determination is "NO", proceed to step S1.
It is determined whether a certain period of time (for example, 15 seconds) has elapsed after answering the dedicated call. If the certain period of time does not elapse here, the process returns to step S3, and step S! Execute the process. In addition, even if a certain period of time has elapsed, wheelchair users will not be able to enter the vehicle.
If the photoelectric device for 3 does not operate, the process moves to step St.
New dedicated car call registration impossible data is calculated by the CPU and set in 1 memory device W13, and even if a call signal from a new dedicated car call button is input to the input device D, the new dedicated car call cannot be registered in the storage device 3. Data prohibits its registration.

On the other hand, when proceeding to step S6, if CPU-
By this, new car call registration enable data is set in the storage device J, thereby making it possible to register a new dedicated car call when a call signal is input to the input device DA by operating a new dedicated car call button. Then, in the next step S9, a dedicated car call signal reading process is executed.

In this embodiment as described above, registration of a newly generated call by the dedicated car call registration device is only possible when the wheelchair boarding detection device operates for a predetermined period of time after stopping at a dedicated hall call. Therefore, the registration of unnecessary calls from the dedicated car call registration device, that is, the registration of dedicated car calls due to mistakes or mischief by ordinary passengers, can be restricted, and the service performance of the elevator can be improved.

In the above embodiment, the case where the wheelchair user boarding detection device is used to control the registration of a new dedicated car call registration device is explained. Of course, you can use it. Further, in the above embodiment, a photoelectric device is used as a device for detecting entry of a wheelchair user, but the present invention is not limited to this.
It is also possible to use an ultrasonic sensor mud switch, etc.
