Description

[Detailed Description of the Invention] This invention relates to an improvement of a device for operating an elevator.

In general buildings, anyone can freely use the elevator by pressing the landing button on each floor or the destination button in the car. However, in so-called Getabaki apartment buildings, where the lower floors of the building are stores and offices and the upper floors are residences, random people can go to the floors where the stores and offices are located, and the residences are not. It is necessary to allow only certain people to go to certain floors. Therefore, normal push buttons and touch buttons are used for the landing button and destination button to go to the floor where stores and offices are located, and switches that are operated with a key are used for the landing button and destination button to go to the floor where the residence is located. There is something that I have designed to use. However, this is inconvenient and not very practical as the key must be carried around.

Therefore, in recent years, so-called so-called methods have been introduced in which the call for a specific floor is registered only when multiple buttons installed at the landing or in the car are pressed in a specific order, or only specific buttons are pressed at the same time. A cryptographic call registration device is used. In addition, the encrypted operating device is also used to change the operating mode using a key-operated switch.

However, with the above-mentioned coded type, if you accidentally press the button in the correct way while trying to do it in a mischievous manner, the call for a specific floor may be registered or the operation mode may be switched. Therefore, the contents of the code are likely to be known to a third party.

This device improves on the above-mentioned drawbacks, and if an incorrect operation is performed, it will not be recognized even if the operation is correct under certain conditions, so that the contents of the code will be disclosed to a third party. It is an object of the present invention to provide an elevator operating device that is hidden from the public.

An embodiment of this invention will be described below with reference to figures.

In the figure, (+) and (-) are DC power supplies, 1a to 3a, 1
b to 3b are the 1st to 3rd floors provided in the car, respectively.
The normally open contacts of the destination buttons on the floors, 1c to 3c are the normally closed contacts of the destination buttons on the 1st to 3rd floors, 11 to 13
are car call registration relays on the 1st to 3rd floors, respectively.
11a to 13a are normally open contacts, 21 to 23 are car position contacts that open when the car approaches the first to third floors, and 24 is a car position contact that operates immediately when energized and returns after a certain period of time when it is deenergized. This is a time relay for detecting erroneous operation, and 24a is its normally closed contact.

Next, the operation of this embodiment will be explained.

Currently, the first and second floors are general floors that anyone can access, and the third floor is a special floor that only certain people can access.

When a passenger who has boarded the car on the first floor presses the destination button on the second floor, contact 2a closes and (+)-2a-3
The second floor car call registration relay 12 is energized by the circuit c-22-12-(-), and is self-held by closing the contact 12a. The call for the car on the second floor is now registered, and the car runs towards the second floor.

When registering a car call on the third floor, press the destination buttons for the second and third floors at the same time, contacts 2b and 3a will close, and (+)-3a-2b-1c-24a-23-
The third floor car call registration relay 13 is energized by the circuit 13-(-), and is self-held by closing the contact 13a. At this time, since the contact point 3c is opened, the car call registration relay 12 on the second floor is not energized. Furthermore, since the contact 3b is closed but the contact 2c is open, the time relay 24 is not energized.

Now, if you press only the destination button for the third floor as a prank or the like, the time relay 24 will operate due to the (+)-3b-2c-24-(-) circuit and the contact 24a will open. Next, when you let go of the destination button for the third floor,
The contact 3b is opened and the time relay 24 starts counting the time limit. Contact 24a during time limit counting
is open, so even if the destination buttons for the third and second floors are pressed during this time, the third floor car call registration relay 13 will not be energized and the third floor car call will not be registered. Further, even if the destination buttons for the third floor and the first floor are pressed at the same time, the time relay 24 is activated by the (+)-3b-1b-24-(-) circuit.

In this way, the call will not be registered for a predetermined period of time after pressing the button incorrectly, even if the button is pressed correctly, so even if you happen to press the button correctly while trying to press it in various ways for mischief, etc. The call is never registered.

When the time limit count ends, the time limit relay 24 returns to normal and the contact 24a closes, so that the initial state is returned and the car call for the third floor can also be registered.

In addition, when the car runs in response to a car call and approaches that floor, the car position contacts 21 to 23 respectively
is opened, the car call registration relays 11 to 13 are deenergized, and the car call is canceled.

In the example, a car call is registered only when specific destination buttons are pressed at the same time.
It can also be applied when registering a hall call or switching the driving style. Moreover, it can be applied not only to pressing specific buttons at the same time but also to pressing them in a specific order.

In addition, even if you press the button correctly for a certain period of time after pressing it incorrectly, you will not be able to register a call. , call registration may be disabled.

As explained above, in this invention, when multiple buttons in the hall or in the car are operated in a specific order, or when specific buttons are operated at the same time, this is recognized as a correct operation, and the above-mentioned specific operation is performed. If a different operation is performed, the system will prevent recognition of the correct operation until a certain amount of time has passed or the button has been pressed a certain number of times. Even if you accidentally perform the correct operation while
It is possible to detect erroneous operations and prevent the contents of the code from being known to a third party.

Claims (1)

[Scope of utility model registration request] If you operate multiple buttons in a certain order among the buttons provided at the landing or in the car, or operate certain buttons among the above-mentioned multiple buttons at the same time,
In an elevator that recognizes this as a correct operation and performs a predetermined elevator operation, there is an erroneous operation detection circuit that detects that an operation different from the above-mentioned specific operation has been performed, and when this erroneous operation detection circuit is activated, a certain period of time has elapsed since then. An elevator operating device comprising a recognition blocking circuit that blocks the recognition even if the predetermined operation is performed until the button is pressed a certain number of times.
