Description

System and method to be connected to CCTV camera, light bar and speaker upon control of shutters of subway station}

The present invention relates to a system and method for interlocking CCTV cameras, warning lights, and speakers during shutter control of a subway station.

CCTV systems include multiple cameras that shoot video, a DVR (Digital Video Recorder) or NVR (Network Video Recorder) server, and a hard disk that compresses the image data of each camera and stores it in a hard disk by connecting multiple cameras with UTP cables. It is composed of disk storage, and is transmitted to the CCTV control center monitoring server that receives the video and audio data of each camera channel through the communication network, and the video of multiple cameras on the multiviewer screen of the monitor of the control PC connected to the CCTV control center monitoring server. Data are monitored.

As CCTV cameras, fixed cameras, dome cameras, pan tilt zoom (PTZ) cameras, and dome infrared cameras having infrared LEDs photographed at night are used.

The camera includes a lens, a camera, and a power supply, and includes a dome or top-covered camera housing covering the lens, and is classified into a fixed camera and a rotary camera.

PTZ cameras are equipped with PTZ (Pan, Tilt, Zoom) control functions, Pan fixes the camera position and moves the camera left and right, Tilt (tilt up, tilt down) is a function that moves the camera up and down, and Zoom In/out provides a function to reduce/enlarge the image screen by focusing the focal length of the camera to a near or far distance.

DVR (Digital Video Recorder) is a digital video recorder that encodes images taken by multiple cameras connected by cables within a 1.7km distance and stores them on the hard disk, and distributes and displays images for each camera channel. It is a device, and includes a screen change switch, a screen splitter, a VCR (video player) sensor, and an alarm controller.

Network Video Recorder (NVR) server is a dedicated PC server that records video data of multiple cameras installed on the network, monitors, manages events, and plays video data from multiple cameras. Digital video data is received and compressed through the device. Since it is an IP-only storage device, there is no need for a device that converts an analog camera video signal into a digital camera video signal, and is a device that replaces the existing digital video recorder (DVR).

1 is a block diagram of a DVR system including a conventional CCTV camera and sensor.

A DVR system including a CCTV camera and a sensor includes at least one camera 710 for photographing CCTV images of a surveillance area; A sensor 712 that detects heat when a fire occurs; A hard disk that is connected to the at least one camera 710 and the sensor 712, is assigned a device ID, is connected to at least one camera that photographs an image of a surveillance area, and stores image data recorded from the cameras. DVR 720 with a built-in disk; A computer and HD monitor 723 connected to the DVR 720 and outputting through a screen splitter (2x2, 3x3, 4x4, 5x5) of each CCTV camera in a surveillance area; The mobile communication terminal 780 is connected to the DVR 720, monitors the video streams of cameras in the surveillance area, generates an alarm at the control PC when an intrusion is detected (the alarm went off), and has a preset mobile phone number of the administrator. A control center server 740 for transmitting an intrusion alarm to; And a control PC 790 equipped with a DVR card installed with a screen splitter client for video analysis and CMS monitoring of CCTV video streams recorded from at least one or more cameras in a surveillance area.

As the sensor 712, any one of a door magnet detector, a human body detection sensor (PIR sensor), an ultrasonic sensor, a wireless door sensor, and a fire detection sensor may be used.

Shutters installed at the entrances and waiting rooms of subway stations are operated for crime prevention by controlling passengers' access after train operation is finished to protect facilities in subway stations. In addition to security shutters, fire shutters that operate in case of fire are also installed in boundary areas such as transit or connecting passages. Even after the end of the subway operating hours, personnel are permitted to clean, inspect, and repair facilities including railroad tracks. In particular, security shutters rely on manual operation, so improvement is needed in terms of station automation.

As a related prior art 1, a "fire shutter control system" is registered in Patent Registration No. 10-1773172.

2 is a perspective view of an existing fire shutter control system.

The fire shutter control system (1) is formed of a ceiling (C) in the building and an inner wall of the building connected to the ceiling (C) (the first inner wall (W1) and the second inner wall (W2)) and the floor surface (B). It is a system that controls the fire shutter that opens or closes the passage.

The heat sensing unit 14 may employ a known technology using a heat sensing sensor that responds to changes in ambient temperature.

The blocking unit 20 is moved by the shutter operation unit 30 while being embedded in the ceiling C in the building to close the passage, thereby preventing the spread of heat or smoke caused by the fire. The passage may be a type of movement passage formed by the ceiling C, the first inner wall W1, and the second inner wall W2 in the building. The blocking unit 20 prevents fire or smoke from a fire generated from one side from moving to the other side by closing the moving passage.

The shutter operation unit 30 may lower the blocking unit 20 based on a detection signal applied from the fire detection unit 10. The shutter operation unit 30 uses a motor driven by a power source, and while being connected to the blocking unit 20, the blocking unit 20 is unwound from the ceiling C so as to move downward, or The unwound blocking part 20 may be wound so as to move upward toward the ceiling C.

The position sensing unit 40 may be disposed on a moving path of the blocking unit 20 to detect the position of the blocking unit 20. The moving path of the blocking part 20 refers to a path in which the blocking part 20 moves along the first inner wall W1 and the second inner wall W2 while being embedded in the ceiling C. In addition, the position sensing unit 40 may be installed on at least one of the first inner wall W1 or the second inner wall W2 to detect the position of the blocking unit 20.

In addition, the position sensing unit 40 may detect the position of the blocking unit 20 using infrared rays, ultrasonic waves, electromagnets, etc., and by a proximity sensor due to contact or non-contact with the blocking unit 20 Can be implemented.

The control unit 50 may control the shutter operation unit 30 according to a detection signal applied from the fire detection unit 10 or the position of the blocking unit 20 sensed by the position detection unit 40. I can.

Specifically, when a detection signal is applied from the fire detection unit 10, the shutter operation unit 30 can be controlled to implement a downward motion of the blocking unit 20, and the detection signal is detected by the fire detection unit 10 When the signal is released, the shutter operation unit 30 may be controlled to implement an upward motion of the blocking unit 20. Here, the downward motion of the blocking part 20 means closing the passage, and the upward motion of the blocking part 20 means opening the passage.

In addition, the shutter operation unit 30 can be controlled to move the blocking unit 20 upward or downward according to the position of the blocking unit 20 sensed by the position sensing unit 40, and the position sensing The lifting and descending motion of the blocking part 20 according to the part 40 is performed.

However, the shutter control system of the existing subway station was not linked with CCTV cameras, warning lights and speakers when controlling the shutter of the subway station, and at the same time as controlling the shutter, the image signal input through the camera adjacent to the shutter is displayed on the 3D Map screen. The shutter was not displayed on the screen, and the shutter was not displayed through the speaker, the shutter control screen was displayed on the 3D Map screen of the subway station, and the up/down/stop commands were not executed through the shutter control screen.
