Abstract

The present invention relates to a character generator that superimposes the floor state of the elevator on a video signal of a surveillance camera installed in an elevator (elevator) used as a means of moving between floors in a high-rise building and transmits it to a monitor or storage device for receiving the same. By superimposing the video signal of CCTV installed in the elevator and the floor display of the elevator (On Screen Display), it monitors the movement of the elevator and helps to check the passenger's boarding / unloading floor recorded in the storage device in the event of an accident. There is a purpose to give.

The configuration of the present invention includes a first receiving end for receiving a camera power supply and an image signal; A second receiving end for receiving a signal output from a power supply and a sensor of a sensor installed in the elevator; A third receiving end controlling a position where the floor display character is displayed; A character generator for reading the sensor information input from the second receiving end and displaying a layer overlapping with the image signal received at the first receiving end; It consists of a transmitter for amplifying and transmitting the video signal output from the character generator to the display device.

Description

Elevator Floor Indicator for Closed Circuit Cameras {Elevator Floor Indicator}

The issue of crime prevention and surveillance, which must prevent more intelligent and advanced crimes, becomes more and more important, and the installation of CCTV for security surveillance is increasing day by day. In addition, as in the case of high-rise apartments, CCTVs are installed at building entrances or lifts (elevators) for the purpose of crime prevention or for tracking after criminals. Recently, there is a case of robbery against women in an elevator, so it is inevitable to install a CCTV camera on the elevator.

The video signal captured by the surveillance camera introduced for the purpose of such a crime is transmitted to the control room or the management room for monitoring the elevator to be monitored through the storage device and the monitor.

In general, when a criminal moves by using an elevator in a crime against a residential area such as a high-rise apartment, it is necessary to monitor the moving floor of the elevator or monitor the movement of the elevator in real time through a monitor. have.

Due to this necessity, the installation of the surveillance camera is directed toward the floor display unit in the elevator, but the exact floor display character cannot be photographed.

In addition, the conventional floor marker generator is difficult to install, and because the elevator operation information must be shared, the elevator is not applicable, there is a problem such as generation of elements that interfere with the elevator operation.

Therefore, in order to solve this problem and effectively monitor the present invention, an elevator floor display character is superimposed on an image signal of a surveillance camera installed in an elevator in such a manner that the installation is easy and there is no obstacle to elevator operation.

In order to transmit the layer display as described above, the present invention is a part of CCTV so that the present invention can be briefly introduced and describe a system equipped with the present invention.

In general, the CCTV is composed of the imaging unit 100, the transmission unit 200 and the display device 300. The imaging unit 100 generally refers to a camera and the transmission unit 500 refers to a wired or wireless transmission of an image signal to the display device 300. The display device 300 refers to a device that makes an image signal visible to a human eye.

1 is a general CCTV installation system, the imaging unit 100 receives power from the elevator 400 to photograph the subject, and the transmission unit uses the transmission / reception terminal by wire or wireless to capture the image signal captured by the imaging unit 100. The transmitted image information is displayed by using the display device 300.

2 is a CCTV system equipped with the present invention, the image signal photographed inside the elevator in the image pickup unit 100 for photographing the subject is floor information in the elevator floor display device 200 receives information detected by a sensor installed on the elevator top Is superimposed on an image signal (On Screen Display) and transmitted to the display device 300.

Since the elevator operates using information of various sensors, sharing information of various sensors mounted on the elevator may cause a problem in safe operation, so the present invention installs a separate sensor in a safe place.

Looking at the present invention in detail to share the power for supplying the image pickup unit 100 in the elevator floor display device, the elevator movement information detected by the two sensors installed separately from the elevator floor display device 200 and the imaging unit 100 ) Is superimposed on the video signal. The layer markers superimposed on the video signal can be freely selected. Rather than converting the signal input to the elevator position indicator to inform the elevator movement status, it is a method of receiving and controlling the information of the sensor 210 separately installed, so it is easy to apply universally and eliminates the elements that hinder the operation of the elevator as much as possible. It is simple to install and operate.

In FIG. 3, the image signal received by the first receiving end 201 is transformed into a stable image signal in the floor display device and then transmitted to an OSD generator. The sensor signal received by the second receiving end 207 is analyzed by the central processing unit (MICOM: 204) and controlled to generate an appropriate floor display character in the character generator. In the central processing unit (MICOM) 204, when there is a KEY input at the third receiving end, the floor display characters are sequentially changed in the display device 320. The layer display device amplifies 203 an image signal overlaid with layer display characters and transmits the image signal to the transmitter 208 for transmission to the display device 320. In addition, the central processing unit (MICOM) 204 stores the changed information in the external EEPROM when the changed information exists.

The sensor of Figure 4 is equipped with a variety of methods, such as photosensor method, RFID method, proximity sensor method according to the elevator installation situation to enable simple installation and stable operation. In addition, the floor display status is always stored in the EEPROM during the power failure of the elevator. To minimize errors and to correct errors caused by the inflow of various noises, it is possible to compare and compare the current status via the reference floor (1st floor). The reset function has been added.

The present invention is designed with low power consumption so that the power of the surveillance camera can be shared (206) without using a separate power supply, minimizes the effects of noise, etc. in a harsh environment, and is characterized by simple installation. .

5 shows a state in which the floor display letters are displayed on the display device 320, and in the case of the basement floor, the letter B (321) is added before the floor letter, and has a function of limiting the floors on which the floor display of the elevator is not to be performed. .

As described above, the present invention increases the installation effect of the surveillance camera in the elevator, it is possible to view the elevator floor of the elevator occupants recorded on the DVR in the event of an accident that facilitates the prevention or post-mortem analysis of the crime, the movement status of the elevator It is possible to monitor in real time through the monitor (guard room or control room), the direction of the camera inside the elevator can illuminate the passenger's face, and it can be installed and operated universally by supplementing the conventional floor display method. This is possible.
