Abstract

PURPOSE:To cause only a particular utilizer to ride out from an elevator at a living floor by transmitting a cage door opening command when a signal decoding device operated when a passenger is decided as a particular utilizer is operated during the stop of a cage. CONSTITUTION:When a cage is stopped at a given lining floor by means of a floor platform call button and a destination button, s particular utilizer inputs a memory code to an input device 1. When the memory code is decoded by a signal decoding device 2 and is decided to coincide with the preregistered one of the particular utilizer, a coincidence signal is transmitted to an elevator door opening control device 11. A door opening command is outputted to a cage door 12, and the door 12 is opened and the particular utilizer rides out from an elevator at a living floor. However, when memory code is not inputted or does not coincide with a registered one, the decoding device 2 does not transmit a coincidence signal, whereby the door 12 is not opened.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for controlling the opening of an elevator door using a personal identification code held by a user.

[Prior Art] In condominiums and the like that are used by specific users, a check for specific users is conducted at the entrances and exits of the building to prevent unspecified persons from freely entering and exiting the building. Similar checks are also performed when registering elevator calls, and these checks are
A C card is inserted into an input device and recognized by a password code held in the IC card, or by inputting a specific password into the input device using a numeric keypad.

FIG. 2 is a block circuit diagram showing a conventional elevator calling device disclosed, for example, in Japanese Patent Application Laid-Open No. 64-87477.

In the figure, (1) is an input device that is installed at the entrance of a building and is used to insert an IC card or operate a numeric keypad to enter a PIN code, and (2) is an input device that is connected to input device (1) and is used to input a PIN code. (3) is an entrance door control device that is connected to the signal decoder (2) and gives a door opening command to the building entrance/exit door (4) based on the result of decoding the code;
(5) is a departure permission button installed inside the elevator car and issues a departure command; (6) is a landing button installed in the elevator landing; (7) is a destination button installed inside the elevator car; (8) is a departure button installed inside the elevator car. ) is an elevator control device that is connected to each of the above-mentioned devices (2), (5) to (7) and gives a predetermined operation command to the car drive motor (9).

A conventional elevator calling device is configured as described above, and when a pin code is input through the input device (1),
The signal decoding device (2) determines whether the input PIN code matches that of a specific user registered in advance.
If they match, a match signal is sent to the entrance door control device (3). As a result, the entrance door control device (3) opens the door (4), allowing the specific user to enter the building.

On the other hand, the signal decoding device (2) sends an elevator hall call signal and a call signal for the floor where the specific user resides, that is, the destination floor of the specific user, to the elevator control device (8). Based on these signals, the control device (8) drives the electric motor (9), that is, the car, and the car is brought to the entrance floor and stands by with the door open. After that, when the specified user gets on the car and presses the departure permission button (5),
The car leaves for the specific user's destination floor, that is, the residence floor.

In addition, the signal decoding device (2) outputs a hall call signal and a car call signal, and the departure permission button (5) issues a departure command.
However, there are cases in which the car is operated by using the general landing button (6) and destination button (7) without doing this.

However, in recent years, with the effective use of land in urban areas and the diversification of buildings, there has been a marked increase in the construction of complex housing in which the lower floors of buildings are divided into store floors and the upper floors are divided into residential floors.

In such buildings, unlike buildings such as condominiums that are used only by specific users, it is impossible to check for specific users at the entrances and exits of the building to prevent unspecified persons from freely entering and exiting the building.

Therefore, in the above-mentioned residential complex buildings, the input device (1) as shown in Figure 2 is installed in the elevator landing or in the car to check for specific users when entering the car. do not have.

[Problems to be Solved by the Invention] In the conventional elevator calling device as described above, a PIN code input device is installed in the hall or inside the car to check for a specific user. If a numeric keypad or the like is used to register a car call for a residential floor, there is a problem in that the password becomes meaningless if operated in front of general passengers (store floor users). Also,
When using an IC card, if a general passenger is on board,
There is a problem in that it becomes possible to invade the residential floor.

This invention was made in order to solve the above problems, and it is possible to allow specific users to get off the train on the residential floor without the knowledge of general passengers, and also to restrict general passengers from getting off the train on the residential floor. An object of the present invention is to provide an elevator door opening control device.

[Means for solving the burden] When the car stops, the elevator door opening control device according to the present invention opens the door if the signal decoding device is operating, and opens the door if the signal decoding device is not operating. It was made so that it would not open.

[Function] In this invention, even if the car stops, the door will not open unless the signal interpretation device determines that the user is a specific user, so general passengers cannot get off the car to the residential floor.

[Embodiment] FIG. 1 is a block circuit diagram showing an embodiment of the present invention, and parts similar to those of the conventional device are designated by the same reference numerals.

In the figure, (11) is an elevator-door control device which is connected to the signal decoding device (2) and gives a door opening command signal to the car door (12) based on the result of decoding the password code.

Next, the operation of this embodiment will be explained.

As is well known, this elevator is operated by a hall call using the hall button (6) in FIG. 2 and a destination call using the destination button (7), but a detailed explanation thereof will be omitted.

When the car is driven as described above and stops on the residential floor,
A specific user inputs a PIN code using the input device (1), and when the code is decoded by the signal decoding device (2) and it is determined that it matches the code of the specific user registered in advance, the signal decoding device (2) sends a coincidence signal to the elevator door opening control device (11). With this, a door opening command signal is output from the door control device (11) to the car door (12), the door (12) opens, and the specific user can get off the car.

However, if the general passenger does not input the PIN code, or if the PIN code is input but does not match the registered one, the signal decoding device (2) does not issue a matching signal.

Therefore, since the control device (11) also does not output a door opening command signal, the door (12) does not open even if the car stops in the habitable position, and general passengers cannot get off the car in the habitable position.

In the above example, the door is closed when the car stops, and the waiting time until the specific user instructs the door to be opened is not shown, but considering the time to insert the IC card, You may also set the waiting time for residence techniques to be longer.

[Effect of the invention] As explained above, in this invention, even if the car stops,
Since the door was not opened unless the signal deciphering device determined that the user was a designated user, general passengers would not be able to get off the train, and the designated user would be allowed to get off the train without the general passengers knowing. In addition, it is possible to restrict general passengers from getting off the elevator to their residences, and it is possible to make the elevator suitable for use in complex residential buildings.
