Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a crime prevention operation device in which the response of an elevator to a specific floor is limited.

[Conventional technology]

Conventionally, as an example of a crime prevention operation device for an elevator, there is one disclosed in Japanese Utility Model Laid-Open No. 58-60662.

That is, a card reader is provided in the elevator car, which identifies a specific person and decides whether or not to register a car call (call registered by the destination button in the car) on a specific floor. Only when a specific person operates a destination button for a specific floor, a car call for the specific floor is registered and made to respond to this, so that the general public cannot enter the specific floor.

[Problems to be Solved by the Invention]

In the conventional crime prevention driving device for an elevator as described above,
Since only a specific person is allowed to call a car on a specific floor, an unfavorable phenomenon occurs when a specific person and an ordinary person ride together. That is, when a car arrives at a specific floor in response to a car call registered by a specific person, the door automatically opens, so the specific person either refuses to disembark at the specific floor to the general public, or he / she must get on before boarding. There is a problem in that it is not desirable for crime prevention because it must be refused, unnecessary human troubles occur, and the general public is given the opportunity to enter a specific floor.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a crime prevention operation device for an elevator that does not give an ordinary person an opportunity to enter a specific floor even when the ordinary person is on board.

[Means for Solving the Problems]

The crime prevention operation device for an elevator according to the present invention, when a car call on a specific floor and a car call on a general floor ahead of the specific floor in the traveling direction of the car are registered, a specific floor passage command that causes the specific floor to pass immediately. When a car call on the general floor ahead of the traveling direction is not registered, the generation of a specific floor passage command is blocked.

[Action]

According to the present invention, when a call from the specific floor car call and a call from the front general floor are registered, the car passes through the specific floor, so that the car responds to the general floor car call and dismounts the public. If the car call on the front general floor is not registered, the car does not pass through the specific floor, so the car arrives at the specific floor with only a specific person on board.

〔Example〕

1 to 3 are views showing an embodiment of the present invention.
FIG. 1 is an overall configuration diagram, FIG. 2 is a block circuit diagram, and FIG. 3 is a flowchart showing a specific floor passage determination operation.

In FIG. 1, (1) to (8) are the first floor to 8 in the car, respectively.
When the destination button (not shown) on the floor is operated, the destination button signal becomes “H”, and the first floor to the fourth floor and the sixth floor to the eighth floor are the general floor, and the fifth floor is the specific floor. (10) is a well-known card reader provided on the operation panel (not shown) in the car, and (11) is AN
D gate, (12) are destination button signals (1) to (4),
Car call registration means (6) to (8) and the output of the AND gate (11), and (13) car call registration means (12)
Deciding means for deciding the traveling direction of the car by inputting the output of the car, (14) a drive control device for controlling the traveling and stopping of the car based on the output of the deciding means (13), (15) a car call It is a specific floor passage determining means for determining whether to stop the car on the 5th floor based on the outputs of the registration means (12) and the direction determining means (13) and issuing the output to the drive control device (14).

In FIG. 2, (18) is a microcomputer (hereinafter referred to as a microcomputer), which has a CPU (18A), a memory (18B), an input circuit (18C) and an output circuit (18D), and an input circuit (18C).
Is connected to a card reader (10) and destination buttons on the 1st to 8th floors, and the drive circuit (14) is connected to the output circuit (18D).
Are connected.

Next, the operation of this embodiment will be described with reference to FIG.
The specific floor passage determination operation program shown in this flowchart is stored in the memory (18B) of the microcomputer (18).

Now, it is assumed that a specific person who goes from the 1st floor to the 5th floor (specific floor) and an ordinary person who goes to the 7th floor (general floor) are on board. A specific person inserts the card into the card reader (10) and presses the destination button on the 5th floor. Here, if the card verification result is correct, the output of the card reader (10) becomes "H". On the other hand, the destination button signal (5) on the 5th floor becomes "H". With this, AND gate (11)
Becomes "H", and the car call registration means (12) registers the car call on the fifth floor. Further, since the ordinary person presses the destination button on the 7th floor, the destination button signal (7) on the 7th floor becomes "H", and the car call on the 7th floor is similarly registered. When the car call is registered in this way, the operating direction of the car is set to the up direction by the direction determining means (13),
The drive controller (14) starts operation of the car in the up direction.

On the other hand, the specific floor passage determination means (15) determines whether or not to stop the car for the car call on the fifth floor.

First, in step (21), it is determined whether the car call on the specific floor (fifth floor) has been registered. In this case, the car call on the 5th floor has been registered, so proceed to step (22) and proceed to the specific floor (5
(Floor), it is determined whether the car call on the floor upstream in the up direction is registered. In this case, since the car call for the 7th floor is registered, the process proceeds to step (23), and a command to pass through the specific floor (5th floor) is output to the drive control device (14). as a result,
The car passes through the fifth floor without canceling the car call on the fifth floor and responds to the car call on the seventh floor. When the car arrives on the 7th floor, the car call on the 7th floor is released, and the ordinary people get off at the 7th floor.

Next, since the car call of the fifth floor is still registered, the driving direction is set to the down direction by the direction determining means (13), and the driving is started toward the fifth floor. Also at this time, similarly to the above, the specific floor passage determining means (15) determines in step (22) whether or not to stop the car in response to a car call on the fifth floor. Floor ~ 1
Since the car call for the floor is not registered, the step (2
It does not proceed to 3), and the specific floor passage command is not output. Therefore, the car responds to the car call on the 5th floor, and when the car arrives on the 5th floor, the car call on the 5th floor is released, and the specific person alone
You can get off at the floor.

Next, if a specific person going from the 1st floor to the 5th floor (specific floor) and an ordinary person going to the 4th floor (general floor) are on board, the specific floor (5th floor)
Since the car call of the floor (6th to 8th floors) in front of the up direction is not registered, the step (21) does not proceed to step (22), the specific floor passage command is not output, and the car is on the 4th floor or It stops on the 5th floor, and a specific person can get off on the 5th floor alone.

In this way, when the car arrives on the specific floor, only the specific person is in the state of boarding.

In the above-mentioned embodiment, when passing through the specific floor, the car call on the specific floor is not canceled and the registration is maintained. However, when the special floor is passed, the car call on the specific floor is canceled and the car is moved to the front floor. When the response is completed, it is possible to display an appropriate display or the like to allow a specific person to re-register the car call on the specific floor.

〔The invention's effect〕

As described above, in the present invention, when the car call on the specific floor and the car call on the general floor ahead of the specific floor in the traveling direction are registered, the specific floor is passed immediately and the general floor in front of the traveling direction is registered. Since the car call is not registered, the specific floor is made to respond. Therefore, it is possible to prevent the general public from having an opportunity to enter the specific floor without refusing passengers to join the vehicle or refusing to disembark at the specific floor. There is an effect that can be done.
