Description

[0001] The present invention relates to a security camera device for an elevator door,

The present invention relates to a security camera apparatus for an elevator door, and more particularly, to a security camera apparatus for monitoring the outside of an elevator equipped with a monitor.

Increasingly, security doors for elevator passengers have recently been installed on elevator doors. Such security windows are also needed for the safety of elevator passengers, as well as for the safety of the elevator exterior, specifically the building corridor.

Fig. 1 shows a conventional elevator equipped with a security window. Fig. 1A is a front view of an elevator door. Fig. 1B is a cross-sectional view taken along line B-B of Fig. 1A together with a hoistway.

As shown in the figure, when the security windows W1 and W2 are installed on the door of the elevator, it is possible to confirm the passenger P1 of the elevator in the hallway through the security window, Since the security of the person (P2) can be confirmed, the number of such security windows is gradually increasing, and the size of security windows is also becoming larger. Recently, the most widely used security window size is 100mmX500mm in each side.

However, for this purpose, security windows W1 and W2 must be provided on both the cage door D1 and the hall door D2 of the elevator. In addition, the elevator door must be fireproof in order to comply with fire regulations. For this reason, the glass used for the security windows (W1 and W2) must be expensive glass having fire prevention function. Also, there is one cage door D1, but one hole door D2 is provided for each layer, so that the number of the hall doors increases significantly in the case of a high-rise building.

That is, since security doors W1 and W2 having fire protection functions are installed in both the doors D1 and D2, there is a problem in that the installation cost is high as well as the material cost and the construction period is long.

However, in a security window having such a structure, it is possible to check the safety of both arrows only when the elevator is stopped as shown in FIG. 1B, and it is impossible to confirm whether or not the other layers that pass the elevator while it is in operation are safe. This problem becomes more evident in the case of a high-speed elevator with a high elevator elevation speed.

Furthermore, when the hallway is dark at night, there is a problem that the safety check of the hallway side is impossible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is an object of the present invention to provide an interior of a building by photographing an emergency situation occurring at night or in a dark corridor and displaying it on a monitor.

And a controller (40) connected to the security camera, the infrared lamp, and the sensing device to control operation of the elements and store data,

When the security camera 10 normally captures a moving picture and senses that the doors 30 and 31 are correctly matched with the doors D1 and D2, the still image is captured under the control of the controller, So that moving images and still images are displayed on the monitor M by the controller.

The sensing device 30 includes an optical sensor 32 provided on the cage door D1 and a light sensor 32 mounted on the hall door D2 at a position corresponding to the optical sensor, And a reflector 34 for reflecting the light toward the light source.

In another embodiment of the present invention, an I / O port 50 for controlling a monitor and inputting / outputting data is provided in a control panel in the elevator cage and connected to the controller 40. The I / O port 50 ) Is connected to a keyboard, a USB or other input / output device.

According to the present invention configured as described above, emergency situations occurring in a dark corridor such as a fire, a robbery or theft event can be greatly improved by security personnel in real time as well as passengers aboard the elevator or passengers waiting in the corridor .

In addition, according to the present invention, the number of expensive fireproof glass security windows can be greatly reduced, and the installation cost and the maintenance cost can be greatly reduced as compared with the conventional art.

The monitor M is installed inside and outside the door or the cage of the elevator. In this embodiment, the monitor M is installed in the door of the elevator, particularly the cage door D1.

As shown in Figs. 2A to 2B, the security camera 10 is installed outside on the surface of the cage door D1 of the elevator. Such a security camera 10 continuously captures a moving image for a designated time under the control of the controller, and captures a still image at a specific time, which will be described later.

An infrared lamp 20 is installed on the surface of the cage door D1 adjacent to the security camera 10. The infrared lamp 20 is installed to photograph the dark building corridor at night with the security camera 10. [ The infrared ray of the infrared lamp 20 emits infrared rays towards the corridor, and may emit infrared rays whenever necessary, or may always emit infrared rays.

In addition, a sensing device 30 is provided to sense when the cage door D1 is exactly aligned with the elevator door D2. The sensing device 30 includes an optical sensor 32 installed in the cage door D1 and a light sensor 32 installed in the hall door D2 at a position corresponding to the optical sensor to receive light from the optical sensor 32, But it is also possible to use another sensing device if necessary. That is, any sensing device is considered to be included in the scope of the present invention only when it detects the moment when the cage door and the hall door are exactly matched.

A window W is formed in the hall door D2 at a position corresponding to the front surface of the security camera 10 and the infrared lamp 20. The window is covered with a transparent glass, Of the viewing angle (A).

Fig. 3A is a view showing another layer other than the one layer, FIG. 3B is a front view of the elevator door of the first floor, and FIG. 3C is a front view showing the display state of the monitor.

As shown in FIGS. 3A to 3C, it is preferable that the security camera 10 and the infrared lamp 20 are disposed so as to be adjacent to each other in the lower side in the range of the window W. 3B, on the first floor, a monitor M is installed on the surface of the hall door D2 to inform passengers waiting for the elevator, and a security camera 10 is installed on the monitor M, (See Fig. 3C). Generally, on the upper part of the monitor, a still image on the hallway side which can be photographed by the security camera 10 on the hallway side of each floor, that is, inside the elevator through the window W is displayed, and a security camera 10 It is preferable to display continuous moving images photographed. In the illustrated embodiment, the building has nine floors, and the first to ninth floor still images are displayed on the monitor M. Of course, such a monitor (M) can also be installed in the building management room if a building management room is present, so that an administrator or a security officer can view the same image. As shown in FIG. 2A, a passenger waiting on the first floor can see the image of the monitor (M) and can check the safety state of the corridor of the entire building. It is natural to see this situation in the management office. Therefore, in the event of fire, robbery or thieves, passengers waiting on each floor, security personnel in the passenger or management room inside the elevator will be able to immediately identify emergencies and respond promptly.

Since the window W needs to be large, it is necessary to cover only the viewing angle A of the camera as described above. Therefore, the size of the window W can be largely reduced compared to the conventional one, and the size of the window W can be reduced to 50 mm x 100 mm. It does not hurt the appearance of. Further, since it is not necessary to form a security window in the cage door D1, it is not necessary to use an expensive fireproof glass for the glass for the window W, so that the cost can be further reduced.
