Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an elevator control device for ensuring the safety of passengers stranded on a passing floor in an elevator that operates to pass through a specific floor.

[Technical background of the invention and its problems]

Equipped with a specific floor passing operation device that has the function of turning a preset floor into a passing floor by preventing registration of landing calls and car calls for a preset floor by operating a specific floor passing switch. In an elevator, if the specific floor pass switch is operated after a user has mistakenly gotten off to the floor they are passing through, the user will not be able to register the hall call even if they press the hall call, so they will have to take the elevator from the floor they are passing through. Unable to board the train, he becomes trapped on that floor, which becomes a kind of closed room.

Passengers trapped on the passing floor in this way cannot go out unless the specific floor switch is released, which could lead to a serious disaster. Furthermore, even if the elevator stops at the nearest floor due to some kind of trouble, the same thing can happen if the nearest floor is a passing floor.

[Purpose of invention]

This invention was developed in view of the above points, and is designed to safely rescue passengers even if they accidentally get off to the floor they are passing while the specific floor pass switch is being operated in an elevator equipped with a specific floor pass operation device. To provide an elevator control device that can

[Summary of the idea]

In order to achieve the above purpose, the present invention detects when a passenger presses the hall call button and sends a rescue signal such as a buzzer or indicator light to the manager's room or an equivalent location. By outputting a call registration permission signal from the corresponding location, it is possible to register a hall call for the floor to be passed through.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

The figure shows an embodiment of the present invention, in which 5 is a specific floor passing switch, 6 is a specific floor passing operation detection relay, and 6-1a
is the normally open contact of 6, 6-1b is the normally closed contact of 6, 7 is the hall call registration button, 8 is the trapped call detection relay that detects a hall call that occurs on the passing floor during operation passing through a specific floor, 8-1a is a normally open contact of 8, 10 is a thyristor for hall call registration, 11 is a hall call registration detection relay, 11-1b is a normally closed contact of 11, and 12 is a terminal that is connected to a passing floor from the manager's room or an equivalent place when driving to pass a specific floor. 13 is a forced call registration relay for the passing floor during passing operation, 13-1a is a normally open contact of 13, 14 is an electronic buzzer attached to the manager's room, 15
is the indicator light installed in the manager's room. P and N are control buses. When the specific floor passing switch 5 is operated, the specific floor passing operation detection relay 6 is energized. 6
The normally closed contact 6-1b is energized by the excitation of 7.
-6-1b-10-11 makes it impossible to register the call for the floor you are passing through. Also, the normally open contact 6-1a is closed. At this time, by pressing the hall call registration button 7 on the passing floor, 7-6-1a-11-1b
At -8, the relay 8 is energized to detect a confinement call, which detects a hall call that occurs on a passing floor during a specific floor passing operation. 8 closes the normally open contact 8-1a, and 8-1a-14 causes an electronic buzzer 15 installed in the manager's room or an equivalent location to sound. The manager learns that there is a user on the passing floor by the sound of the electronic buzzer 15, outputs a registration permission signal by operating the registration permission switch 12, and
-11-1b-13 energizes the forced call registration relay 13 of the passing floor during passing operation. The normally open contact of 13-1a is closed by the excitation of 13, and 13-1a is closed.
The hall call registration permission relay 11 is energized by 1a-10-11, and the hall call of the passing floor is registered. When 11 is excited, 7-6-1a-11-1
At step b-8, the relay 8 for detecting a call for confinement is deenergized, and as a result, at step 8-1a-14, the electronic buzzer 14 in the manager's room or a corresponding place stops sounding. In addition, by 8-1a-12-11-1b-13, forced call registration relay 1 of the passing floor during passing operation
The excitation of 3 is released. Hall call registration detection relay 1
1 is deenergized when the elevator is in service and the call is canceled by a circuit not shown. Similar operations are repeated while the specific floor passage switch 5 is being operated.

Instead of the electronic buzzer 14 installed in the manager's room or an equivalent location, an indicator light 15 can be used to notify the manager and perform similar operations.

[Effect of idea]

As explained above, according to the elevator control device of the present invention, when a passenger attempts to register a call at a passing floor while the passing switch is operated in an elevator equipped with a specific floor passing operation device,
By sounding an electronic buzzer installed in the manager's room, the manager can confirm that there are customers on the floor they are passing through, and the manager's office can issue a call registration permission signal to enable call registration. Therefore, the safety of users confined to the passing floor can be ensured.
