Description

A control system for in and out based on scenario and method

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

Many companies and users who provide CCTV-based integrated control solutions install large screens in the control room to monitor real-time video and install integrated control solutions on the PC to control the area allocated to the monitors. Recently, as the major facilities are located in the city with a lot of floating populations or the fences or rail line boundaries are replaced with CCTVs, solutions that integrate access control and video control have become important. However, if there is an object or person trying to break into the surveillance zone, it is quite difficult for the watcher to see the video following the intruder's track.

In particular, there is no connection between the access control device and the CCTV. Until now, access control surveillance solutions have only been able to investigate the time of intrusion when an intruder occurs and view the recorded video on a digital video recorder (DVR) or a network video recorder (NVR). If an intrusion or similar situation occurs, troublesome manual work must be done to track the intruder's movement path by CCTV in real time. In addition, the installation of CCTV in the optimum place for interworking with the access control device is not all interlocking. A complete access control system and CCTV linkage must be able to track and prevent intruders or similar actors in video.

To this end, products that integrate video control solutions with access control solutions have recently been released. In addition to the management of the visitors, the abnormal video may be shown to the monitor. However, even in this case, it can be effective in buildings or limited ranges, but in a wide range of surveillance environments, such as complex large buildings, fences, or barbed wire boundaries, it is not possible to track and show the intruder's route.

Japanese Laid-Open Patent Publication No. 2010-231422 discloses a method for performing processing according to a scenario when an abnormality occurs using a corresponding processing scenario.

The present invention is to provide an access control system that can effectively track the intruder by setting a scenario suitable for the facility or environment to anticipate and monitor the path of the intruder in advance.

Like reference numbers in the drawings denote like elements. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

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

Referring to FIG. 1, the scenario-based access control system 1 (hereinafter referred to as an access control system) of the present invention includes a plurality of cameras 1 to N (101 to 10N) and a plurality of doors 121 to 123. An access control server connected to a plurality of access control devices 1 to N (111 to 11N), a plurality of cameras 1 to N (101 to 10N) and a plurality of access control devices 1 to N (111 to 11N) provided in the 130). Each may be connected by a communication network, for example LAN, 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 a manager's selection, creates a scenario through mapping the camera and the access control device, and generates an event in the access control device. In this case, the camera image according to the scenario may be automatically displayed on the screen.

The plurality of cameras 1 to N 101 to 10N may be PTZ cameras that are disposed at a fixed position at a specific place and have a pan / tilt / zoom function. The camera may receive various images while moving and / or panning and / or tilting and rotating the zoom lens or adjusting the zoom magnification by zooming in or out of the zoom lens. The camera may detect an object by dividing a specific area into a plurality of monitoring areas and monitoring each monitoring area by a preset method. At this time, in the preset method, each surveillance area is monitored while moving or rotating according to a preset preset. The camera may be wired to the access control server 130 to transmit and receive images and control data. Here, although only a wired connection is shown, the present invention is not limited thereto and may be configured wirelessly. Each of the plurality of cameras 1 to N 101 to 10N may be given an ID as its own unique identification information.

The access control devices 1 to N (111 to 11N) are provided at each of the doors 1 to N (121 to 12N), and an accessor or visitor recognizes the user information, for example, face recognition, fingerprint recognition, iris recognition, and the like. It may be an input means such as a password input or a sensor means. If the accessor or visitor recognition is successful, the door is opened. In addition, the recognition information or input information may be transmitted to the access control server 130, and the door may be opened when authentication is successful. In addition, when entering or leaving the person or the visitor, it may transmit the personal information or access time to the access control server 130. Each of the plurality of 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 occurrence signal to the access control server 130 when an unauthorized person or visitor (hereinafter referred to as an “intruder”) attempts to pass through the door.

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

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

For example, when an event occurrence signal is output from the access control device 1 111 provided in the door 1 121 and an alarm signal is generated, an activated scenario among three scenarios registered in the access control device 1 111. The video taken by the mapped camera is automatically displayed on the screen.

The access control server 130 is in charge of general management and operation of the access control system 100 and controls the 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, an event occurrence signal is received from the access control device 1 111. 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 access control device 1 111 to allow the mapped cameras of the scenario to photograph the surveillance area according to a set condition. The access control server 130 simultaneously records images of the cameras and simultaneously displays images of the cameras mapped to the scenarios on one screen. The detailed configuration of the access control server 130 will be described later with reference to FIG. 3.

Conventional access control monitoring solutions have a unique role depending on the characteristics of each device. For example, CCTV would monitor a specific area, NVR or DVR would record and play video, and access control would only manage access. In this case, access management is not easy even if each system is not linked or linked. This is because first, software for video surveillance, access control, and video recording and playback must be installed and operated separately. Secondly, even if the integrated control software for access control and video surveillance is installed and operated, the compatibility between the equipments is not compatible and the supervisor's operation is required to cope with sudden or emergency situations. Here, the operation of the monitor means that after an alarm such as an abnormal entry occurs in the access control device, the monitor must find and reproduce the video of the relevant CCTV, and in order to track the intruder's track, observe all CCTVs in the expected area to find the intruder. . The technical limitation of such a passive and supervisor-dependent solution is simply that CCTV and access control devices only work together, and there is no fully integrated access control solution.

The access control system 100 according to an embodiment of the present invention is configured to set a scenario suitable for a facility or environment to predict and monitor an intruder's track in advance, and integrate an image that can be automatically placed on a screen and tracked. Access control solution.

Normally, camera ID and access device ID are matched with database for camera image and access device interworking. For example, when the access device ID # 4 and the camera ID # 6 are matched, if an alarm occurs in the access device ID # 4, the monitor may view the image of the camera ID # 6. In most cases, the intruder is moving to another location, so the watcher cannot identify the intruder in camera ID # 6. The observer must visually observe all prospective cameras and find the intruder until the intruder passes through another entry. It is easy to find moving intruders in buildings and facilities that are simple in structure and limited in size, but tracking large and complex buildings or fences and fences is very difficult to track.

The access control system 100 according to an embodiment of the present invention provides an integrated control solution based on scenarios such as intruder occurrence, accident situation, fire, and the like. That is, the access control system 100 makes a predictable course path in advance in the access device where the intruder is alerted, registers the cameras in advance, and registers the registered scenarios and the cameras are stored in a database. If an intruder alarm occurs by an intruder, the observer can observe the intruder's behavior with all cameras in the registered scenario and predict the final target area. Such scenarios can be used not only for intruders, but also for the purpose of protecting and preventing major installations such as fire, flooding and earthquake scenarios.

When the scenario extractor 133 receives the event occurrence signal from the event detector 132, the scenario extractor 133 extracts a scenario registered in the access control device where the event occurs from the scenario DB 160.

The camera controller 134 outputs a camera control signal so that the mapped cameras of the scenario extracted by the scenario extractor 133 capture an image. The camera control signal may include a shooting start signal, a PTZ control signal, and the like. The camera receiving the camera control signal photographs the surveillance area under the set condition.

The image output controller 135 receives an image photographed by one or more cameras and transmits the image to the manager terminal 140. The image output controller 135 performs signal processing on the input image and converts the image to conform to the standard of the manager terminal 140. The image output controller 135 may record the image output in real time to the storage device 150. In this case, an event occurrence time or the like may be inserted into the image as metadata.

The image output controller 135 may preferentially display the images input through the mapped camera of the scenario on an output device such as the manager terminal 140. At this time, according to the extraction order of the plurality of scenarios registered in the access control device where the event occurred, for example, according to the scenario priority, the images input from the cameras mapped to the scenarios are displayed in the divided area of the monitor screen. Can be controlled.

When the event detector 132 receives the event occurrence signal, the alarm unit 136 outputs an alarm signal to the manager terminal 140.

The event detector 132, the scenario extractor 133, the camera controller 134, the image output controller 135, and the alarm 136 are hardware such as a DSP (Digital Signal Processor) dedicated to realizing the respective functions. May be realized by a computer such as a CPU (Central Processing Unit).

The manager terminal 140 is a terminal used by an administrator or a security person who manages the access control system 100 and may be a PC or a mobile terminal. The manager may control the access control system 100 through the manager terminal 140. In one embodiment of the present invention, the manager terminal 140 creates and registers a scenario in the access control devices 1 to N (111 to 11N), and the access control devices 1 to N (111 to 11N) and the cameras 1 to 1 in the scenario. A user interface capable of mapping N 101 to 10N, respectively. In addition, the manager terminal 140 may display a scenario list and a mapping list between the camera and the access control device, and may perform modification, addition, or deletion. The manager terminal 140 displays an image of the mapped cameras of the scenario on the monitor. The manager terminal 140 may set an image size, a number of simultaneous display images, an image display position, and a plurality of scenario activation orders by setting display conditions using an interface. When a plurality of scenarios are registered in the access control device where an event occurs, camera images of each scenario may be simultaneously displayed on one screen according to the display condition. Alternatively, camera images of all scenarios registered in the access control device where the event occurred may be simultaneously displayed on one screen.

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

The scenario DB 160 stores a scenario generated by the manager terminal 140 and registered for each access control device. The scenario is a script in which an access control device and a plurality of cameras are mapped according to an intruder's predicted movement path. The physical positional relationship between the plurality of cameras may be set in a matrix structure. Accordingly, each camera may be linked with cameras arranged in east, west, north and south based on its own. The physical location relationship setting may be set for all cameras by scenario or regardless of the scenario. The scenario DB 160 may be included in the access control server 130.

4 is a diagram illustrating an example of a display image according to an embodiment of the present invention.

The degree of freedom of equipment installation and control software should be high enough for the monitor to be monitored and the environment. If a watcher observes a person with a camera who is trying to do something wrong or illegal, he or she needs to track the person's movements. To this end, an embodiment of the present invention displays the selection means on the top, bottom, left and right of the image. The position of each selection means represents the physical positional relationship between the cameras set in a matrix structure. Referring to FIG. 4, direction indicators such as arrows are displayed on the top, bottom, left, and right sides of the image as selection means. When the right direction indicator is selected, an image of a camera set to be located on the right side (east) of the camera capturing the currently displayed image is displayed. When the left direction indicator is selected, an image of a camera set to be located on the left (west) of the camera capturing the currently displayed image is displayed. When the Up direction indicator is selected, an image of a camera set to be located above (north) of the camera capturing the currently displayed image is displayed. When the down direction indicator is selected, an image of a camera set to be positioned below (south) of the camera capturing the currently displayed image is displayed.

The access control system 100 according to an embodiment of the present invention may provide a selection means for the display image by setting a physical position relationship in a matrix structure between a plurality of cameras of the entire surveillance area or between a plurality of cameras for each scenario. . This allows tracking of intruders' tracks in real time. That is, the access control system 100 according to an embodiment of the present invention can track and anticipate the behavior when an intruder or a similar actor occurs with a simple database manipulation and a direction indicator on an image to prevent the occurrence of an unspecified event in advance. It can also be interlocked with not only access control devices but also detection devices.

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 manager or the complementary party creates a scenario in which the camera and the access control device are mapped using the user interface of the manager terminal and stores the scenario in the database. Here, the scenario is a predicted movement path of the intruder at the door, and one or more scenarios registered in the access control device provided at the door may be generated. Addition, modification, or deletion of scenarios and mappings can also be performed using the user interface.

When an event occurrence signal is input from the specific access control device to the access control server, a scenario registered in the corresponding 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 manager terminal (S505). The manager terminal displays the received image. At this time, by setting the display condition using the interface of the manager terminal, it is possible to set the image size, the number of simultaneous display images, the image display position, and the sequence of activation of a plurality of scenarios. The access control server may record the image along with the image transmission.

When the direction indicator selection signal displayed on the image is received, the access control server receives the image photographed by the camera corresponding to the selection signal and transmits it to the manager terminal (S507). The direction indicator display can be set on the image using the interface of the manager terminal, and a selection signal is generated by clicking the direction indicator and transmitted to the access control server. The physical positional relationship is set in matrix structure between some cameras. Accordingly, the access control server may control a camera corresponding to the selection signal, receive an image photographed by the camera, and transmit the image to the manager terminal.

The scenario-based access control system according to an embodiment of the present invention registers one or more scenarios corresponding to an event that may occur in the access control device, and monitors images input from the cameras mapped to the scenarios according to the scenario when the event occurs. Allow for optional display. Therefore, since the monitoring video of the area where the event occurs is preferentially displayed on the monitor based on the scenario, the monitoring performance of the access control system can be improved by allowing the operator to easily monitor the status of the monitoring area.

An apparatus according to the present invention may include a processor, a memory for storing and executing program data, a permanent storage such as a disk drive, a communication port for communicating with an external device, a user interface such as a touch panel, a key, Devices, and the like. Methods implemented with software modules or algorithms may be stored on a computer readable recording medium as computer readable codes or program instructions executable on the processor.
