Description

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

At night, when the corner of the elevator stopped at the floor and the door opened, a crime occurred in which Norihiro (female in q#) was the only one in the car and got into the car and assaulted *If-. ing. As a passenger, you cannot see the state of the landing on the floor you are trying to get off from from inside the car, so there is nothing you can do about it.

The purpose of this invention is to improve the above-mentioned problems, and to provide an elevator security device that displays the information of the landings on each floor inside the car to notify the situation of the landings and prevent danger. shall be.

An embodiment of the present invention will be described below with reference to FIG.

In the figure, (lA) to (5A) are industrial television cameras (hereinafter referred to as television cameras) installed in the elevators on the 1st to 5th floors, respectively, and capture images of the respective g# places.
IB) ~ (5B), each elevator car is on the 1st floor ~
(6) is the car position contact that closes when the car approaches the 5th floor; (6) is the stop decision relay contact that closes when the car decides to stop; (1)
) is a television receiver (hereinafter referred to as a television receiver) equipped with a clock contact that closes at night (for example, from 10 p.m. to 6 a.m.) and a cage with internal pressure. , respectively 1st floor ~ 5th floor
Photographing the landing on the floor. At night, the clock contacts (7
) is closed.

Now, when the car approaches the 4th floor and decides to stop, the 4th floor car position contact (4B) and the stop decision relay (61) close.
(With a $1 circuit, the TV camera inside the house + 81t
: is activated, and the situation at the landing on the 4th floor is imaged. If there is no suspicious person on the fourth floor based on the footage, the passenger can wait until then, and the car will stop on the fourth floor and the door will open. Now, passengers can feel safe getting out of the car. When the door closes, the stop decision relay contact (set) opens and the TV receiver (8
) images also disappear.

If the image from the TV receiver ($) shows that there is a suspicious person in the landing on the 4th floor, the passenger can press and hold the door close button (not shown) on the in-car control panel and the car will stop. However, the door does not open, and the call for the 4th floor is held, and the driver continues toward the next called floor. In this way, the risk of being hit by a suspicious eight is avoided.

It should be noted that if the door close button or pass button (not shown) is held down, the robot may run to the top floor, bottom floor, or the next floor.

Furthermore, if the stop decision relay contact (6) is omitted, the video of the landing area on each floor will always be monitored. Also, the clock contact ())
If you omit it completely, you can receive the Eirin at the landing even during the day.

FIGS. 2 and 3 show another embodiment of the invention, which is the same as FIG. 1 except as shown.

In the figure, (→, (→) are DC power supplies, (IC) to (5C) are person detectors (mud switch, ultrasonic scanning (2D) to (5D) are position contacts that open when the heel approaches the 2nd to B floors, respectively (IE) to (5D).
1) are call registration relay contacts that close when a car call is registered by the destination buttons (not shown) for the 1st to 5th floors in the car, and (1F) to (5F) are for the 1st to 5th floors. With the front call detection relay, (11Fa) ~ (5Fa
) is its normally open contact, (1'F'b) ~ (IFe),
(21$b) ~ (274) , (3Fb) ,
(5!Fa) and (number n) are normally closed contacts, and (9) is an upstream relay contact that closes when the car runs uphill.

Assuming that the car is now running uphill and all car calls from the 1st to 6th floors are registered, the up direction relay contact (9) and the car call registration relay contact (1) for the 1st to 5th floors are registered.
Illusion (51C) is closed. When the car approaches the second floor, the car position contact (2D) opens, so the contact (IF) is deenergized by the front call detection relay (IF) for the first floor.
b) ~(lFe) is closed. Now, (”) −+9
1- (5D) -(4D) -(3D) -(21C
) −(lFb) −(2F)−(−) circuit,
The front car call detection relay (21') for the 2nd floor is energized, and the contacts (2Fb) to (2F (1) open. Therefore, the front car call detection relay (3F) for the 3rd to 6th floors is activated.
(51F) is not energized. Additionally, when the car approaches the third floor, the car position contact (3D) opens, so the second floor front call detection relay (2F) is deenergized and the contact (21
Ft+) to (gya) are closed. Now, the 3rd floor front call detection relay (3F) is energized, as described above.
Contact (3F1)).

(3Fc) a Since it is open, the front call detection relays (4F) and (ay) for the 4th and 6th floors are not energized.

The same applies to other floors. In particular, when 1? is driving up, the forward call detection relay (1?
) to (5F) will be energized.

Currently, the car is running up near the 2nd floor, and if a car call for the 4th floor is registered, the 4th floor forward call detection relay (4F) is energized and the contact (4Fa) is activated as described above. is closed. Here, if there is a person in the landing on the 4th floor, the person detector contact (4C) on the 4th floor will close, so (4A) -
(apa) -(4c)-+711g+ circuit allows the television camera (8) inside the car to capture an image of the situation at the landing on the 4th floor. From this, even if passengers do not constantly monitor the television receiver (8), they will be able to know that there are people at the platform they are trying to get off from, and will be able to take the above-mentioned avoidance measures. I can do it.

Although this embodiment has been shown for uphill driving, it is obvious that it can also be applied to downhill driving and for hall calls. Further, the human detector contacts (10) to (50) or the watch contacts (7) may be omitted.

Furthermore, a plurality of television receivers (8) may be provided to display one or more landing locations.

If the person detectors (10) to (5C) to the east operate, they may be pressed as follows and displayed in the car.

(7) A separate indicator light is provided below the floor number indicator light of the position indicator in the car and is turned on.

(a) Make the call registration light (built into the destination button inside the car) blink.

As explained above, in this invention, a television camera is installed at the landing on each floor, and one of the cameras is selected and the image is received by the television receiver in the car, so passengers in the car can be informed of the situation at the landing. Therefore, it is possible to take measures to prevent the car from stopping.

In addition, when it was detected that there was a person at a landing, the TV receiver in the car was forced to receive the image of that landing, so even if the TV receiver was not constantly monitored, it was possible to detect the presence of a passenger in the car. You can tell them where to board.
