Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for operating an elevator in a crime prevention manner.

Recently, crimes have been occurring that take advantage of the fact that elevator cars are closed rooms and assault passengers (particularly women). Therefore, various proposals have been made as a countermeasure. For example, if a specific button inside the car is pressed or a passenger in the car makes a noise, the system will stop the car at the nearest floor and give the passenger a chance to escape from the car. be.

However, if there is no one on the nearest floor, it is not safe enough and may even be convenient for the criminal.

This invention is intended to improve the above-mentioned problems, and aims to provide a security operation device for an elevator that can stop the car on a floor where there are people when a passenger is attacked by a thug.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, (+) and (-) are DC power supplies, 1Aa is the landing call registration relay contact that closes when the first floor landing upbound call is registered, and 2Aa, 2Ab to 5Aa, 5Ab
2Ba, 2Bb to 6Ba, 6Bb are the 2nd floor up call registration relay contacts on the 2nd floor to the 5th floor.

Car position contact that opens when you are on the 3rd to 6th floors, 10 is a security button installed inside the car, 11
is an abnormality detection relay, 11a to 11d are normally open contacts, 11e is also a normally closed contact, 12a, 12b
13 is a door closing confirmation relay contact that closes when the landing door and car door (hereinafter simply referred to as the door) are fully closed; 13 is a travel relay contact that closes while the car is running; 14 is a stop command when energized. Stop command relay that issues 1
5a and 15b are upward direction relay contacts that close when the car is running uphill; 16 is a forward call detection relay; 16a and 16b are its normally closed contacts; and 17 is a relay that is opened while the car is running and is closed after the car has stopped. A time relay contact that closes after a certain period of time; 18 is a run command relay contact that closes when a run command is given to the car, and opens after passing the door zone (range where floor doors can be opened and closed); 19 is a run command relay contact that closes when the car is stopped; The door zone relay contact 20, which opens when the door is in the door zone of the desired floor, is a door control relay that issues a door close command when energized and issues a door open command when deenergized.

Next, the operation of this embodiment will be explained.

Normally, when the car is stopped on the first floor and the door is open, the door zone relay contact 19 is open. At this time, when a car call on the 6th floor, for example, is registered in the car, the car call registration relay contact 6c is closed. Now, when a run command is issued, the run command relay contact 18 closes and (+)-17-18
-20-(-)- circuit allows door control relay 20
is energized and the door begins to close. When the door is closed, the car runs and the travel relay contact 13 is closed. When the car approaches the 6th floor, the car position contact 6D closes and (+)-11e-6C-6D-13-14-
The stop command relay 14 is energized by the (-)- circuit, a stop command is issued, and the car stops at the 6th floor. At this time, the time relay contact 17 is open and the door zone relay contact 19 is open, so
The door control relay 20 is deenergized and the door opens. After a certain period of time has elapsed in this state, the time relay contact 17 closes and returns to the initial state.

Suppose now that a passenger who boarded the car from the first floor registers a call for the car on the sixth floor as described above, and while the car is ascending, a thug who rides with him assaults the passenger. When the victim presses the security button 10, the abnormality detection relay 11 is energized, the contacts 11a to 11d are closed, and the contact 11
e is open. At this time, door close confirmation relay contact 1
Since 2a and 12b are closed, the abnormality detection relay 11 maintains itself. Since the car call registration relay contact 6C is disconnected by opening the contact 11e, the stop circuit due to the car call becomes insensitive. At this time, if an up-hall call on the 5th floor is registered, up-hall call registration relay contacts 5Aa and 5ab are closed. Now, when the car is on the third floor, the car position relay contact 3E is open and the upward direction relay contact 15b is closed, so (+)-5Ab-6E-15b-
The forward call detection relay 16 is energized by the circuit 16-(-)-, and the contact 16a is opened. That is, energizing the forward call detection relay 16 means that
It is detected that a hall call is registered on the floor in front of the car in the running direction, and the fact that the car is deenergized means that it is detected that there is no hall call ahead. Now, when the car approaches the 5th floor, the car position contact 5D
is closed, (+)-5Aa-5D-13-14-
The stop command relay 14 is energized by the (-)- circuit, and the car stops at the 5th floor. In other words, since no hall call is registered on the 4th floor, which is the nearest floor, hall call registration relays 4Aa and 4Ba are both open, and as soon as the car approaches the 4th floor, the car position contact 4D closes. However, the stop command relay 14 is not energized, so the train passes through the fourth floor, which is the nearest floor, and stops at the fifth floor, where the hall call is. When the door opens, there will be passengers waiting at the fifth-floor landing who have registered their calls, making it harder for the criminal to continue committing the crime and making it easier for the victim to escape. In the above case, the same is true when a call to the fifth floor is registered, and the contact 5Ba is closed, so the car stops. Normally, the train does not respond to calls coming down the hall while driving up, but it will stop if an abnormality is detected. In addition, if the door opens on the 5th floor, the door close confirmation relay contact 12
Since a is opened, the abnormality detection relay 11 is deenergized and returns to the initial state. Note that if a hall call is registered on the 4th floor, which is the nearest floor, the hall call registration relay contact 4Aa or 4Ba is closed, and when the car approaches the 4th floor, the car position contact 4D is closed. (+)-4Aa-4D-13-14-(-)- or (+)-4Ba-4D-13-14-(-)-
The stop command relay 14 is energized by the circuit,
The car stops at the fourth floor, which is the nearest floor. From then on, 5
The situation is the same as if the vehicle had stopped on a floor, making it easier for the victim to escape.

If the security button 10 is pressed during uphill driving and there is no call to the front hall, the front call detection relay 16 is deenergized and 16a and 16b are closed. Therefore, when the security button 10 is pressed, (+)-11c-16a-15a-13-
14-(-)- circuit, the stop command relay 14
is energized, the car is stopped at the nearest floor in the up direction where there is no hall call, for example the 4th floor, and the driving direction is quickly reversed so that it is driven to the floor where there is a hall call in the down direction. That is, when the stop command relay 14 is energized, (+)-11d-16b-12b-
Since the door control relay 20 is held by the circuit 1E-20-(-)-, the door close command is not released and the door does not open. Here, the driving direction of the car is reversed to the downhill direction. Although this circuit is omitted, it can be easily constructed by, for example, creating a pseudo call on the first floor. The car now shifts to downhill operation and starts running toward the first floor. If the car approaches the first floor, (+)-11b-1D-13-14-(-)-
The stop command relay 14 is energized by the circuit,
The car stops on the first floor. At this time, the car position contact 1E is open, and the door zone relay contact 19
Since the time relay contact 17 and the time relay contact 17 are also open, the door control relay 20 is deenergized and the door opens. That is, when there is no call for the front hall, the car is returned to the first floor where there is a high possibility that there are people near the hall.

It will be easily understood from the above explanation that if the security button 10 is pressed while the car is running downhill, the car will stop at that floor if a hall call is registered. If there is no call from the front hall, the front call detection relay contact 16a is closed, but the upward direction relay contact 15a is open, so the stop command relay 14 becomes insensitive and the car goes straight to the first floor. .

Although it is assumed that the vehicle is stopped on the first floor when there is no front hall call, the present invention is not limited to this, and the vehicle may be stopped on a floor where there is a possibility that there are people near the hall.

Furthermore, although the description has been made assuming that the victim in the car presses the security button 10, it is possible that the present invention can be applied not only to such passenger identification operations, but also to automatic detection of passenger movements, screams, etc. Of course.

Furthermore, the roof floor is usually a place for crime, so if the crime prevention button 10 is pressed, you can stop on the roof floor without opening the door and reverse the driving direction. That makes it desirable.

As explained above, in this invention, when an abnormality occurs with a passenger in the car or a passenger performs a specific operation, the car will not stop at the nearest floor unless a hall call is registered on the nearest floor. Since the car is stopped at a floor where a different landing call is registered than the nearest floor, the victim in the car can easily escape by stopping at a floor where there are people near the landing. can.
