Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a car monitoring device for monitoring the inside of an elevator car.

[Prior Art] Conventionally, car monitoring devices for monitoring the inside of an elevator car have been disclosed in Japanese Utility Model Application Publication No. 58-48669 and Japanese Patent Application Laid-Open No. 6
As shown in Publication No. 3-171781, a TV camera is installed inside the car, and images inside the car taken by this TV camera are displayed on monitor TVs installed in the manager's room or the room on the hill, and management is thereby carried out. The inside of the car was monitored by people and occupants.

[Problems to be Solved by the Invention] In the conventional elevator car monitoring device described above, only the television camera that constitutes the device is installed inside the car,
Generally, they are installed on the ceiling or corner of the car, or from a design standpoint, they are installed so that they are not noticeable to passengers. Therefore, although passengers who have boarded the car can intuitively recognize that the inside of the car is under surveillance, they cannot know the actual inside-the-car surveillance situation displayed on the monitor television. Therefore, even if a passenger with criminal intentions boards the car, there is a problem in that the effect of suppressing the criminal consciousness and behavior in advance is low.

This invention was made to solve the above-mentioned problems, and an object thereof is to provide an elevator car monitoring device that can suppress criminal acts by criminals and improve the crime prevention effect.

[Means for Solving the Problems] The elevator car monitoring device according to the present invention displays an image taken by a television camera inside the car in addition to the monitor TV outside the car, so that the passenger's own moon can be monitored inside the car. It is equipped with a monitor television to enable monitoring.

[Function] In this invention, the image taken by the television camera is displayed not only on the monitor TV outside the car but also on the monitor TV inside the car. The situation can be monitored, giving passengers a sense of security that crime prevention monitoring is being carried out, and giving criminals a psychological deterrent that they are being watched, improving the crime prevention effect. let

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 and FIG. 2 show an embodiment of a car monitoring device for a caravan according to the present invention.

In Figure 1, 1 is a manager's room, 2 is a monitor TV installed in the manager's room 1, and 3 is an elevator hoistway installed inside an office building or condominium. A hoisting machine 5 is installed in a machine room 4 formed at two ends of 3. The main rope 6 wrapped around the sheave 5a of the lifting machine 5
A car 7 that ascends and descends into the hoistway 3 and a counterweight 17 are connected to both ends of the hoistway.

Inside the car 7, a television camera 8 for photographing the interior and a monitor television 9 for displaying images taken by the television camera 8 to passengers inside the car are installed. 10 is the TV camera 8 and the in-car monitor TV 9
A video signal transmission cable 11 is an elevator cable that also serves to transmit video signals, one end of which is connected to the lower part of the car 7, and the other end of which is connected to the terminal board 12 attached to the inner wall of the hoistway 3. It is connected to the. Reference numeral 13 denotes a video signal cable that connects one end of the elevator cable 11 and the in-car monitor television 9.

In addition, the terminal board 12 and the monitor television 2 in the manager's room 1
A cable 14 for transmitting video signals connects between the two.

FIG. 2 shows a connection diagram between the television camera 8, the car side monitor television 9, and the manager's room side monitor television 2.

The monitor televisions 8 and 2 generally have human output connectors for video input and video output, so that the video signal input to the video input connector is simultaneously output to the video output connector and displayed on the monitor display. is also output. In the car monitoring device of this embodiment configured as described above, the video signal inside the car taken by the television camera 8 is supplied to the monitor TV 9 inside the car through the cable 10, and the situation inside the car is displayed. .

On the other hand, the video signal photographed by the television camera 8 is sent to the output connector (not shown) of the car-side monitor television 9 and the cable 13. The signal is transmitted to the monitor television 2 in the manager's room 1 through the elevator cable 11, terminal board 12, and cable 14, and displayed.

In this embodiment, the images taken by the television camera 8 are displayed on the monitor television 9 in the car and in the manager's room 1.
Since the images are simultaneously displayed on the monitor TV 2 of
The situation inside can be monitored. This not only gives passengers a sense of security that they are being monitored, but also allows them to monitor their behavior and that of other passengers through the screen of the monitor television 8, which eliminates the discomfort of having to directly monitor each other.
In addition to preventing mutual distrust, the potential criminals themselves are also shown on the monitor TV 8, so the psychological impact of being watched by fellow passengers on criminals trying to play pranks is significant. This will have the effect of suppressing criminal activity.

FIG. 3 is a block diagram showing another embodiment of the invention.

In FIG. 3, the same reference numerals as in FIG. 2 represent the same parts. Further, 15 is a video signal generating device, and 16 is a changeover switch for selectively connecting the monitor television 9 on the car side to the monitor television 2 (video output connector) and the video signal generating device 15 on the manager's room side.

In another embodiment configured in this way, by operating the changeover switch 16, the image from the television camera 8 can be displayed on the monitor television 9 in the car, and
A video signal from the video signal generator 15 can also be supplied.

Therefore, for example, during the day when it is relatively safe, indoor information inside the building and general TV programs are transmitted from the video signal generator and displayed on the monitor TV 8 inside the car, and at night, images inside the car 7 are displayed. It becomes possible to display multiple functions such as

[Effect of the invention 1 As described above, according to the present invention, a monitor TV is installed inside the car, and the inside of the car can be monitored in the manager's room, etc., and at the same time, the passenger can also monitor the car himself/herself. This gives passengers a sense of security that they are being watched, and also allows them to monitor each other's behavior from the monitor TV screen, which also helps potential criminals feel that they are being watched. This has the effect of having a large impact, suppressing criminal acts by criminals, and improving crime prevention effects.
