JPH0252830A - Barglarproof operation device for elevator - Google Patents

Abstract

PURPOSE:To produce an eminent burglarproof effect by providing a stop blocking device to register a cage call in a specified time zone during the night and block the stop of a cage at a target floor by operating a burglar push button in a cage when a man is present at a station at the target floor. CONSTITUTION:During a timer between 2 o'clock AM and six o'clock PM, a clock relay 6W is energized, and a contact 6W1 is closed. When a passenger riding on at a first floor registers a cage call at a third floor, a relay contact 3C is closed, and with a burglar button X pushed, a corresponding relay 20 is energized, a relay contact 203 thereof is closed, and a display lamp lighting OFF relay 13H is energized. This operation enables a man at a station to recognize a cage position. Further, when a man is present at a third floor station, a man body detecting relay contact 3L is closed, and when the cage approaches a third floor, a cage position contact 3P is closed, and a stop block relay 12 is energized. This constitution opens a contact 121 thereof, prevents energization of a stop command relay 9, and prevents the stop of the cage at the third floor.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement in a security operation device for an elevator.

[Conventional technology]

Because the doors of elevator cars close and become a closed room, there are many crimes where passengers, especially women, are violently assaulted.

As a driving device to prevent this crime, for example,
As disclosed in Publication No. 8-144079, even if there is a call for a landing during a specific time period at night, passengers do not respond to the call and go directly to their destination floor. In the unlikely event that a car call occurs at the destination floor, a guidance display will be displayed inside the car asking you to register a car call other than the destination floor, and an operating system will be installed to prevent two people from boarding the same car at night. Proposed.

[Problem to be solved by the invention]

With the above conventional device, there is no problem with the above-mentioned device because if there is a suspicious person at the platform during a specific time period at night and the suspicious person registers a platform call, the car will not stop at that platform, but the suspicious person will not register the platform call. This was a problem because the cars were sometimes ambushing passengers on the floor, and in this case the cars would stop on that floor.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to provide a crime prevention driving device that prevents passengers in a car from encountering a suspicious person even if there is a suspicious person at the landing during a specific time period at night.

[Means to solve the problem]

The purpose of this is to install a device that detects the presence of a person at the platform, and when a security button is operated, if there is a person on the platform floor where the car call is registered, the driver's panel will indicate that there is a person on the destination floor. This is achieved by providing a display to register the floor call and providing a device that prevents the car from stopping at that floor.

[Effect]

During specific hours at night, register car calls and operate the security button inside the car. At that time, if there is someone on the landing floor where the car call was registered, the driver board will not stop on that floor, so you will have to stop at another floor! , will be displayed to record. Therefore, passengers can register other floors and get off at a floor where no one is present at the landing, providing a significant crime prevention effect.

〔Example〕

An embodiment of the present invention will be described below with reference to five drawings. Note that the elevator is assumed to be in service on the 1st to 5th floors.

Figure 2 is a schematic diagram of the elevator landing seen from the front.
is the platform door, B is the platform indicator light, C is the platform call button,
D is a human body detector, such as a mud switch, which is installed in the front of the landing door and detects the presence of a person in the landing.

In Figure 1, + and - are DC power supplies, IC-5C is a call registration relay contact that opens when a car call on the 1st to 5th floors is registered, and IL to 5L are terminals for the landings on the 1st to 5th floors, respectively. A human body detection relay contact that closes when it detects that there is a person on the floor, ■P to 5P are car position contacts that close when a person is on the 1st to 5th floors, and 6W is a time detection device, for example, 2 a.m. to 6 a.m., 6W□ is its normally open contact, and 7H is the contact for the landing call stop decision relay that opens even if a stop due to landing preparation is decided.
8C is a car call stop decision relay contact that opens when a stop due to a car call is determined, 9 is a stop command relay that gives a stop command to the car when energized, and 10C is a guide indicator light provided on the operation panel inside the car. , 12 is a stop prevention relay that is energized to prevent the stop when there is a person at the landing, 12 □ is its normally closed contact, 12 □ is its normally open contact, and 13H turns off the landing indicator light B when it is energized. 20 is a relay for crime-prevention driving that turns off the indicator light when energized, and 20.
~203 is its normally open contact.

204 is the normally closed contact or the in-car security button contact, and Y is a door open confirmation relay that detects when the door is opened.

Next, the operation of this embodiment will be explained.

At any time other than between 2:00 a.m. and 6:00 a.m.

Clock relay 6W is de-energized, and clock relay contact 6W□
is open. Therefore, when the car is determined to stop due to a hall call, the hall call stop determination relay 7H is closed, and when the car is determined to be stopped due to a car call, the car call stop determination relay contact 8C is closed, so that the stop command relay is closed. 9 is energized and the car stops.

Next, from 2 a.m. to 6 a.m., the clock relay 6W is energized and the clock relay contact 6W is closed. Currently, the car is on the 1st floor, and when a passenger who boarded from the 1st floor registers a car call on the 3rd floor, the 3rd floor car call registration relay contact 3C
is closed, and when the security button X is pressed, the security driving relay 20 is energized. The security driving relay contact 203 is opened and the 1 indicator light extinguishing relay 13H is energized, thereby turning off the landing area indicator light, so that the car position is not recognized by people at the landing area. If there is a person on the 3rd floor platform, human body detection relay contact 3L
is closed.

A control circuit (not shown) causes the car to travel upward, and when it approaches the third floor, the car position contact 3P closes, and the stop prevention relay 12 is energized, so the stop prevention relay contact 121 opens.
The stop command relay 9 is not energized and the car does not stop at 3Wi.

In addition, the stop prevention relay contact 12□ is closed, the guide indicator light 10G is lit, and a message is displayed, for example, ``There are people in Hall R, so please drive to another floor.'' So the passengers, for example 4
Register the floor call button.

Therefore, the opportunity for passengers in the car to ride together with other passengers is avoided.

When the car further ascends and approaches the 4th floor, the stop prevention relay 12 is deenergized and the car call stop decision relay contact 8C is closed, so the stop command relay 9 is energized and the car stops at the 4th floor. , the door opens and passengers can exit safely. Note that when the door opens, the door open confirmation relay contact Y opens, the security driving relay 20 is deenergized, and the vehicle returns to its initial state.

In this way, according to this embodiment, if there is a person at the destination floor landing, the car will not be stopped at that floor.

In order to travel to another floor, passengers can avoid encountering danger.

〔Effect of the invention〕

According to the present invention, by registering a car call and operating a security button inside the car during a specific time period at night, if there is a person at the destination floor landing, a guidance display is lit on the driver's panel;
Since the car is not stopped on that floor, passengers can get off at a floor where no one is present, which has a significant crime prevention effect.
