Description

O.S.D Generator for the CCTV CAMERA which a floor indication of an elevator becomes}

The rise of residential spaces that accompanied the development of the industrial society entailed the introduction of elevators. As a side effect, elevators in high-rise buildings such as apartments and buildings have become a very closed place and have a high possibility of crime. For this reason, many elevators with closed-circuit televisions in consideration of crime prevention are currently introduced.

Looking at the characteristics of the elevator, an elevator or an elevator (lift) is a device for moving people or cargo up and down along a pair of guide rails installed inside a vertical passage inside the building. It is called a cage or car, and it connects the counterweight, the cage and the counterweight, which hangs relative to the weight of the cage to reduce the load of the cage, the guide rail, and the cage to move the cage up and down. It is composed of a wire rope (hanging) wire that is caught on the rotating wheel of the winch. These elevators are widely used as a means of transporting high-rise buildings. In Korea's building law, a building owner has to install a lift in order to build a building with six floors or more and a total floor area of 2,000 square meters (excluding buildings prescribed by Presidential Decree). The size and structure of this law is prescribed by Ordinance of the Ministry of Construction and Transportation (Rev. 99 · 2 · 8 Law No. 5895).

Elevators are enclosed spaces that are very vulnerable to the physical violence of people inside the elevators. Also, the anonymity of high-rise buildings such as apartments makes these violence more easily. As a preventive device in such a situation, CCTV can be used very usefully, and the installation of CCTV to the elevator described above is used as a very useful means for crime prevention as well as on-site preservation after the crime. In general, the video taken through the CCTV created in the elevator is observed through a monitor in the control room or security room that manages the elevator.

Looking at the structure of the closed-circuit television system installed in these elevators, generally follow the CCTV system, usually divided into the image pickup unit, the transmission unit and the display device. In this case, the image pickup unit captures an image of the camera and captures a subject by using a device such as a CCD camera or a camcorder, and analyzes the electrical signal and transmits it to the transmission unit. The transmitter is divided into a wireless transmission system and a wired transmission system. In the case of a relatively simple wired CCTV, a coaxial line is used to transmit an image captured by the image pickup unit to the display unit. In addition, the wireless transmission system transmits the image information captured by the image pickup unit to the display device through a unique channel. Finally, the display device displays a subject photographed by the imaging unit through a monitor, and includes not only a monitor but also a storage device and a camera controller.

The present invention is a device for displaying the floor position of the elevator on the display device as a way to obtain useful information about the interior and the situation of the elevator in the control room and security room that observes the display device for the CCTV installed in the elevator described above. . The floor position indicator which displays the floor number of elevator directly related to the present design is attached to the car position indicator by DIGITAL (DOT MATRIX) method using LED on the TRANSOM panel of the upper part of the inside of the car. It is produced by inserting acrylic plate, and the products which display hierarchical number and destination direction are used, and various methods related to this have been proposed.

The present invention intends to express the location of the elevator together with the video of the CCTV installed in the elevator on the display device. For this purpose, the image signal of the imaging unit and the data indicating the floor position of the elevator are displayed on the display device.
