Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator operating system, and more particularly to an improvement in an operating system for rescuing all passengers in the event of a disaster.

[Prior art]

If a disaster (earthquake, fire, power outage, etc.) occurs while the elevator is running, the elevator will come to an emergency stop and the elevator will stop running. It is designed to drive to a specific evacuation floor (usually the first floor) and rescue all passengers.

However, it may happen that the emergency stop position has already reached the evacuation floor, but the door opening zone of the evacuation floor is not yet reached. In this case, it is usually difficult to automatically drive the car and land it on the evacuation floor. This is because the position detection mechanism of the floor selector detects that the car has already reached the evacuation floor, so the driving direction of the car cannot be determined.

To improve this, the car stops at the evacuation floor zone,
If the door is not in the open zone, forcefully determine the driving direction, drive the car to a floor other than the evacuation floor, and then
It is proposed that the vehicle be driven to the evacuation floor again.

In FIG. 1, floors 1 to 9 are the 1st to 9th floors, and the 2nd to 5th floors are express zones EXP where there are no landings.

In such an elevator, when the corner 10 stops within the zone of the first floor 1, which is the evacuation floor, as shown in the diagram, and is not in the door opening zone, it is forced to operate upward and pass through the express zone. The train will stop at 6th floor 6 and drive to 1st floor 1 again.

Driving like this in the event of a sudden disaster is undesirable as it will delay the rescue of guests.Also, if you are using all non-A power sources, you may have to
It is uneconomical because 1 unit of electricity is consumed in 2 units.

[Purpose of the invention]

An object of the present invention is to provide an elevator operation system that can quickly operate the car to all evacuation floors and rescue passengers even if the car stops in the evacuation floor zone, without wasting time in the express zone. is to provide.

[Summary of the invention]

If traveling in the express zone is a waste of time, passengers can be rescued in the shortest driving time by forcing the train to drive from its stop in the difficult road zone to the open-door zone.

In order to accomplish this, the present invention makes it possible to forcibly determine the entire driving direction by installing a position detector within the door opening zone.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

In the figure, 10 is the cam installed at corner 1o, 5vvc is the cam that is operated by the position detection switch SW', DZ is the door opening zone of 1st floor 1, FZ is the floor zone of 1st floor 1, and 8WIt-
The cam SWC operates by touching the 1 position detection switch. P
FZS is a contact point of a relay (not shown) that operates when the car is in the open door zone DZ on the first floor 1; 11 is a contact point of a relay (not shown) that operates when the car is in door opening zone DZ on the first floor 1; 11 is operated by a floor zone contact FL. Relay 12 is a relay operated by the door opening zone contact, 13 is a relay operated by the position detection switch SW, and 114 is a downward direction relay.
15 is a rising direction relay, and F8 is a disaster occurrence signal contact, which closes when, for example, the 1-volt power supply is established and the 2-V beta becomes operational. (+) (-) indicates the operating power supply.

Relative relationship between position detection switch sw and cam SWC (1)
, t = If the car stops on the row zone side, SW and SW
Do not touch C (contact SW is closed!). (2)
From the door opening zone DZ onwards, the SW and SWC are set to be in touch (the contact SW remains open) within the floor zone I='Z. In the same figure, SW
The sw'i basket and SWC' are placed inside the tower, but there is no problem in placing the sw'i cage and SWC' inside the tower. Also,
The SW and SWC may also be used in common with other devices (for example, end floor reduction gearing, etc.).

Next, the entire operation of the embodiment will be explained.

Assume that due to the occurrence of a disaster (power outage), the elevator stops in the first floor zone FZ outside the door opening zone DZ of the first floor 1.

When the emergency (in-house) power supply is established and the V-Beta is ready for operation, the disaster occurrence signal contact FS closes. Since the car has stopped in the floor zone FZ, the floor zone detection contact PL is closed and the floor zone contact V-11 is turned ON. The corner is outside the open door zone DZ! , +h, so
The door opening zone detection contact DZS is open, and the door opening zone 1JV-12 remains OFF. Further, since the position detection switch SW is not touched by the cam SWC, the circuit is closed, and the position detection switch SW (+)V-13 is turned on. Circuit (+) k's 11-33- 1 zb,
-14-(-) is formed, and the downward direction relay 14 is
Turn on. By turning on descending direction 171/-1, 4, the elevator moves to the evacuation floor 1st floor 1 level (door opening zone DZ
), begins descending operation towards. When the handle 1° descends and the cam SWC touches the position detection switch S■, the contact sW opens and the position detection relay 13 becomes OL! '
F L, contact 13. is open.

As a result, the descending direction relay 14 goes to 0FFL, and the innovator stops. The car stopped in the door opening zone DZ, the door opened, and the passengers were rescued.

The Queen explained about envelopers installed in buildings without basements, but if there is a basement and the car stops below the level of the first floor, V-15 in the upward direction is
By pressing N, the elevator operates upward, stops in the door opening zone DZ, and opens the door.

In this example, the direction was determined by installing all the position detection devices within the door opening zone, but if the evacuation floor is the lowest floor, the direction may be determined using the signal from the door opening zone detection relay on the lowest floor. .

〔Effect of the invention〕

According to the present invention, passengers can be rescued quickly and the amount of force required can be saved.

Claims (1)

[Scope of Claims] 1. An elevator operation device in which a floor adjacent to an express section is set as an evacuation floor and the car is returned directly to the evacuation floor in the event of a disaster, wherein the car is located near the evacuation floor. 1. An elevator operating device characterized in that the elevator is configured to detect that the elevator has stopped, to drive the elevator to the evacuation floor by using a complete direction determining circuit for causing the elevator to travel in the direction of the evacuation floor.
