The present invention relates to a scenario based access control system and method.

Many companies and users who provide integrated control solution based on CCTV install a large screen in the control room to monitor the real time video and install the integrated control solution on the PC to control the area assigned to the monitor. Recently, as the main facilities are located in the downtown area with a lot of floating population, or CCTV is replacing the fence or the border of the fence line, the integrated solution of access control and video viewing is becoming more important. However, when there is an object or person intending to enter the surveillance area, it is quite difficult for the observer to observe the image of the intruder.

In particular, there is no link between access control device and CCTV. To date, access control surveillance solutions have been used to investigate the time of intruders' intrusion and to view recorded video from a digital video recorder (DVR) or a network video recorder (NVR). If an intrusion or similar situation occurs, it is troublesome to manually track the intruder's route through CCTV in real time. Also, installing CCTV in the optimal place for interlocking with access control device is not all interlocked. A complete access control system and CCTV interworking should be able to track and prevent an intruder or similar actor in advance.

To this end, products integrating video control solutions into access control solutions are being released. In addition to managing the passengers, they can also show the video to the supervisor in case of an abnormal visitor. However, this can also be effective in a building or a limited range, but in a widespread surveillance environment such as a complex large building, fence, or fence boundary, it can not track the intruder's trail and show it to the watcher.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Like reference numbers in the drawings denote like elements. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a block diagram schematically illustrating a scenario-based access control system according to an embodiment of the present invention.

1, a scenario-based access control system 1 (hereinafter referred to as an access control system) includes a plurality of cameras 1 to N (101 to 10N), a plurality of doors 121 to 123, A plurality of access control devices 1 to N (111 to 11N) provided in a plurality of access control devices 1 to N (111 to 11N) and a plurality of cameras 1 to N (101 to 10N) 130). Each of which can be connected to a communication network, for example, a LAN or TCP / IP.

The access control system 100 according to an embodiment of the present invention selects a camera and an access control device according to the administrator's choice, creates a scenario through mapping between the camera and the access control device, , The camera image according to the scenario can be automatically displayed on the screen.

The plurality of cameras 1 to N (101 to 10N) may be a PTZ camera having a Pan / Tilt / Zoom function, which is disposed at a fixed position in a specific place. The camera can receive various images while moving and / or panning and / or tilting the camera by the driving device, zooming in or zooming out the zoom lens, and adjusting the zoom magnification. The camera can detect an object while dividing a specific area into a plurality of surveillance areas and monitoring each surveillance area by a preset method. At this time, in the preset method, each surveillance region is monitored while moving or rotating according to a preset preset. The camera is connected to the access control server 130 by wire to transmit and receive video and control data. Here, only the wired connection is shown, but it is to be understood that the present invention is not limited thereto and can be configured wirelessly. Each of the plurality of cameras 1 to N (101 to 10N) may be assigned an ID as unique identification information thereof.

The access control devices 1 to N (111 to 11N) are provided in each of the doors 1 to N (121 to 12N), and the entrance and exit control devices 1 to N (111 to 11N) Input means such as a password inputting means, and sensor means, and opens the door when the passenger or visitor is successfully recognized. Also, the authentication information or input information may be transmitted to the access control server 130, and the access door may be opened when the authentication is successful. In addition, the access control server 130 can transmit personal information or access time and the like to / from the accessing party or visitor. Each of the access control devices 1 to N (111 to 11N) and / or the doors 1 to N (121 to 12N) may be given an ID as its own unique identification information. The access control devices 1 to N (111 to 11N) output an event generation signal to the access control server 130 when an unauthorized accessor or visitor (hereinafter referred to as an 'intruder') passes the entrance door.

The access control system 100 according to an embodiment of the present invention may include a plurality of cameras 1 to N (101 to 10N) and a plurality of access control devices 1 to N (111 to 11N) one to one, one to many, Many-to-many mapped scenarios can be created to increase the scalability and flexibility of cameras and access control devices. The scenario is a script that predicts an intruder's movement path when an event occurs in an access control device, for example, when an intruder passes through a door, and maps at least one camera on the anticipated movement path to an access control device. One or more scenarios registered in one access control device may be generated depending on the number of travel paths to be predicted.

2 is a diagram illustrating an example of a scenario according to an embodiment of the present invention. 2 shows an example in which the first to third scenarios are registered in the access control device 1 (111) provided in the door 121 (121). In the first scenario, the camera 1, the camera 5, and the camera 6 are mapped to the access control device 1 (111). When the first scenario is activated, the camera 1, the camera 5, Is automatically displayed. In the second scenario, camera 1, camera 2, and camera 3 are mapped to access control device 1 (111). When the second scenario is activated, images of camera 1, camera 2, and camera 3 are automatically displayed on the screen. In the third scenario, the camera 1, the camera 2, the camera 6, and the camera 10 are mapped to the access control device 1 (111). When the third scenario is activated, Is automatically displayed. In the first to third scenarios, priority may be set as an activation sequence for display when an event occurs.

For example, when an event generation signal is output from the access control device 1 (111) provided in the door 121 (121) and an alarm signal is generated, the activated scenario The image captured by the mapped camera is automatically displayed on the screen.

The access control server 130 performs overall management and operation of the access control system 100 and controls interworking between the cameras 1 to N (101 to 10N) and the access control devices 1 to N (111 to 11N). The access control server 130 receives an event generation signal from each of the plurality of access control devices. For example, the access control device 1 (111) receives an event occurrence signal. The access control device 1 (111) transmits an event occurrence signal to the access control server 130 when an event occurs. The access control server 130 extracts one or more scenarios registered in the entrance control device 1 (111) and allows the mapped cameras of the scenario to photograph the surveillance area according to the set conditions. The entrance control server 130 simultaneously displays the images of the cameras mapped to the scenario on one screen while recording the images of the cameras. The specific configuration of the access control server 130 will be described later with reference to FIG.

Conventional access control monitoring solutions have inherent roles according to the characteristics of each equipment. For example, CCTV monitors specific areas, video recording and playback of NVR or DVR, and access control of access control devices. In this case, access control is not easy even if each system is not linked or linked. The reason for this is that first, software for video surveillance management, access control management, video recording and playback must be separately installed and operated. Second, even if the integrated control software for access control and video surveillance is installed and operated, not only the compatibility between the devices is not suitable, but also the manipulation of the supervisor is required to cope with an unexpected or emergency situation. The supervisor must find and reproduce the video of the CCTV after an alarm such as abnormal access is generated in the access control device. In order to track the intruder's activity, the CCTV of the expected area should be observed to find the intruder . The technological limitations of this passive and monitor-dependent solution are simply CCTV and access control devices, but not a fully integrated access control solution.

The access control system 100 according to an embodiment of the present invention can predict a behavior of an intruder in advance and set a scenario suitable for a facility or an environment to be monitored, Access control solution.

Usually, camera ID and access device ID are matched to the database in order to link camera image and access device. For example, if the access device ID # 4 and the camera ID # 6 are matched, if the alarm is generated in the access device ID # 4, the surveiller can see the video of the camera ID # 6. In most cases, the intruder is moving to another location, so the watchdog will not be able to identify the intruder with camera ID # 6. Until the intruder passes through the other access device, the observer must visually observe all expected cameras and find the intruder. While buildings and facilities that are simple in structure and limited in size can easily locate moving intruders, it is very difficult to track down intruders when monitoring large or complex buildings or fences or fences.

The access control system 100 according to an exemplary embodiment of the present invention provides an integrated control solution based on scenarios of an intruder occurrence, an unexpected situation, and a fire. In other words, the access control system 100 registers the cameras in the scenarios in advance, which are predictable in the access device in which the alarm is generated by the intruder, and the registered scenarios and cameras are stored in the database. If an access device is alerted by an intruder, the observer can observe the intruder's actions with all the cameras in the registered scenario and anticipate the final target area. These scenarios can be used not only for intruders, but also for the purpose of protecting and proactively protecting major facilities such as fire, flooding, and earthquake scenarios.

FIG. 3 is a view schematically showing the access control server and peripheral structures of FIG. 1 according to an embodiment of the present invention.

1 and 3 together, the access control server 130 includes an event detection unit 132, a scenario extraction unit 133, a camera control unit 134, a video output control unit 135, and an alarm unit 136 .

The video output control unit 135 performs signal processing of the input video and converts it to conform to the standard of the administrator terminal 140. [ The video output control unit 135 can record the video output to the storage device 150 in real time. At this time, an event occurrence time or the like can be inserted into the video as metadata.

The image output control unit 135 may cause the image input through the mapped camera of the scenario to be preferentially displayed on the output device such as the administrator terminal 140. [ At this time, according to the extraction order of the plurality of scenarios registered in the access control apparatus in which the event is generated, for example, according to the scenario priority, images input from the cameras mapped to the scenario are displayed in the divided areas of the monitor screen Can be controlled.

The alarm unit 136 outputs an alarm signal to the administrator terminal 140 when the event detection unit 132 receives the event occurrence signal.

The event detection unit 132, the scenario extraction unit 133, the camera control unit 134, the video output control unit 135, and the alarm unit 136 may be hardware (e.g., a DSP (Digital Signal Processor) , Or may be realized by executing a program by a computer such as a CPU (Central Processing Unit).

The administrator terminal 140 is a terminal used by an administrator or a security official who manages the access control system 100, and may be a PC or a mobile terminal. The administrator can control the access control system 100 through the administrator terminal 140. In one embodiment of the present invention, the administrator terminal 140 creates and registers a scenario in the access control devices 1 to N (111 to 11N), and controls the access control devices 1 to N (111 to 11N) And N (101 to 10N), respectively. In addition, the administrator terminal 140 may display, modify, add, or delete a scenario list and a mapping list between the camera and the access control device. The administrator terminal 140 displays the images of the mapped cameras of the scenario on the monitor. The administrator terminal 140 can set the image size, the number of simultaneous display images and the image display position, and the order of activating the plurality of scenarios by setting display conditions using the interface. When a plurality of scenarios are registered in the access control apparatus in which an event has occurred, the camera images of the respective scenarios can be simultaneously displayed on one screen in the order set in the scenario according to the display condition. Alternatively, the camera images of all the scenarios registered in the access control apparatus in which the event has occurred can be simultaneously displayed on one screen.

The storage device 150 may include a video recording device such as a DVR or an NVR. The administrator terminal 140 and the storage device 150 may be integrally formed.

The scenario DB 160 stores scenarios generated by the administrator terminal 140 and registered for each access control apparatus. The scenario is a script in which the access control device and a plurality of cameras are mapped according to the predicted movement path of the intruder. A physical positional relationship between a plurality of cameras can be set in a matrix structure. Accordingly, each camera can be interlocked with a camera disposed on the basis of the camera itself. The physical location relationship setting can be set for all cameras regardless of scenarios or scenarios. The scenario DB 160 may be included in the access control server 130.

There should be a high degree of freedom in setting up the equipment and setting up the control software to suit the target and environment to be monitored by the supervisor. If a surveiller observes a person who is attempting to act abnormally or illegally with a camera, it is necessary to track the movement of the person. To this end, an embodiment of the present invention displays selection means on the upper, lower, left, and right sides of the image. The position of each selection means represents the physical positional relationship between cameras set in a matrix structure. Referring to FIG. 4, direction indicators such as arrows are displayed on the upper, lower, right, and left sides of the image as selection means. When the right direction indicator is selected, the image of the camera set to be located on the right (east) side of the camera for photographing the currently displayed image is displayed. When the left direction indicator is selected, the image of the camera set to be located on the left (west) side of the camera for photographing the currently displayed image is displayed. When the Up direction indicator is selected, the image of the camera set to be located on the upper side (north side) of the camera for photographing the currently displayed image is displayed. When the down direction indicator is selected, the image of the camera set to be located at the lower (south) side of the camera for photographing the currently displayed image is displayed.

The access control system 100 according to the embodiment of the present invention can provide the selection means to the display image by setting the physical positional relationship between a plurality of cameras in the entire surveillance region or a plurality of cameras in each scenario in a matrix structure . Accordingly, it is possible to track an intruder's behavior in real time. In other words, the access control system 100 according to an embodiment of the present invention tracks and predicts an intruder or similar actor when a simple database operation and a direction indicator on the image are generated, thereby preventing occurrence of an unspecified event in advance It can be linked with the access control device as well as the sensing device.

5 is a flowchart schematically illustrating a scenario-based access control method according to an embodiment of the present invention.

Referring to FIG. 5, a scenario in which a plurality of cameras and a plurality of access control devices are mapped is registered in the access control device (S501). Here, the administrator or the supplementary person creates a scenario in which the camera and the access control device are mapped using the user interface of the administrator terminal, and stores it in the database. Here, the scenario is the predicted movement path of the intruder in the entrance door, and one or more scenarios registered in the entrance control device provided at the entrance door can be created. Adding, modifying, or deleting scenarios and mappings can also be performed using a user interface.

When an event occurrence signal is input from the specific access control device to the access control server, the scenario registered in the access control device is extracted (S503).

The access control server causes the camera mapped to the access control device of the extracted scenario to start shooting according to the setting condition, and transmits the received image to the administrator terminal (S505). The administrator terminal displays the received image. At this time, by setting the display condition using the interface of the administrator terminal, it is possible to set the image size, the number of simultaneous display images and the image display position, and the order of activation of a plurality of scenarios. Access control server can record video together with video transmission.

Upon receiving the direction indicator selection signal displayed on the image, the access control server receives the image captured by the camera corresponding to the selection signal and transmits the image to the administrator terminal (S507). A direction indicator can be set on the image using the interface of the administrator terminal, and a selection signal is generated by clicking the direction indicator and transmitted to the access control server. A physical positional relationship is established between the plurality of cameras in a matrix structure. Accordingly, the access control server controls the camera corresponding to the selection signal, and can receive the image photographed by the camera and transmit the image to the administrator terminal.
