The present invention relates to an access management system and a method thereof, and more particularly, to an access management system and a method for transmitting an access situation of a managed person entering and exiting a predetermined area to a subscriber who requests management of the managed person by using an image. It is about a method.

An access control system that prevents unauthorized persons from entering and manages the entry of authorized persons is already in common use, and manages the access information of authorized personnel in a computerized way by preventing entry of miscellaneous or dangerous persons. Doing.

Figure 1 shows the configuration of a general access management system, a basic configuration that can be used for various purposes. First, when the user 20 contacts the card reader 15 with the registered security card 25 in order to open the door 10 that cannot be manually operated from the outside, the card reader 15 receives the corresponding security card ( Acquire authentication information from 25 and transmit the corresponding authentication information to the access management server 17. The access management server 17 maintains the state of opening or closing the door 10 based on the corresponding authentication information. If the access management server 17 has a remote management function, the access contents may be checked through the manager terminal 31 of a remote site connected through the communication network 30. If the authentication fails or the door 10 is forcibly opened and closed without the security card 25, the information may be notified to the subscriber's mobile communication terminal 32 as text information. Alternatively, when the remote administrator wants to check the access information of the user 20 through the mobile communication terminal 32, the access management server 17 sends the information to the mobile communication terminal 32 in the form of a text message. It may be provided.

Figure 2 shows the configuration of the access control system for confirming the information of the person in a contactless manner. A receiver capable of obtaining information by contactlessly detecting the authentication means 45 by a subject 40 having an authentication means (for example, short-range wireless transmission means, etc.) 45 for authenticating entry and exit without contact. When passing through the detection area of 51, the receiver 51 obtains the authentication information of the authentication means 45, provides it to the authentication server 52, and permits access when authenticated, and authentication fails. Records it or otherwise notifies the administrator. Or, if there is a doorway that can be opened and closed, the doorway can be closed. When the system is used for the purpose of identifying the entry and exit of the management subject 40 rather than the authentication of the entry and exit, the authentication server 52 is based on the authentication information obtained from the authentication means 45. The access information of 40 may be recorded, and if necessary, the access information may be notified to the subscriber terminals 131 and 132 that have requested the management of the management target person 40 through the communication network 130.

In addition to the above methods, methods of obtaining access information using the body information of the management subject and providing the same to the subscriber who wants to manage the access of the management subject are also used.

The above methods are useful for subscribers who want to check the moving and current status of the supervised person, not just access control.The current status of office workers or working workers, or whether the children attend school or school, It is used to ensure safe mobility and academic fidelity.

However, since both the method of using the security card and the method of using the contactless authentication means are access systems based on simple character information, the security card or the authentication means can be stolen, so the reliability is low and the body information is authenticated. When used as a means, theft is low, but it takes a long time to check the physical information and also restricts who can be authenticated at one time. It is very difficult to confirm the entry and exit of the supervised person by applying the above system to the factory commute time, the school gate during the school day, the school entrance before and after the lecture, etc.).

In particular, if you want to check your child's return to and from school, caregivers who want to check your child's return to and from school are simply looking for your child to go to school. We want to make sure we are going to and from school, but existing systems are unable to effectively provide this additional information to subscribers.

An object of the present invention, which is newly proposed to reliably identify a plurality of subjects of management, is to identify a movement and authentication information of a subject of management having a non-contact authentication means through a sensor receiver to detect a camera disposed at a position where the subject of management is moved.

Embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

3 is a conceptual view showing the configuration of the access management system according to an embodiment of the present invention, an example of the case applied to enable the parents to check the back and forth school of the students to be managed remotely. However, the same configuration can be widely applied to factories, academies, companies, and the like.

First, RFID receivers 101 and 102 for detecting RFID tags which are non-contact authentication means placed on the teaching gate 100 and carried by students 141 and 142 to be managed, and detection provided by the RFID receivers 101 and 102. The RFID server 110 receives the information (the unique information of the RFID tag) and checks the validity of the detection information and provides the information to the DVR 120 when the validity is valid. The students from the cameras 121 and 122 having a plurality of cameras 121 and 122 and located in a direction in which the students 141 and 142 travel through detection information and time information provided by the RFID server 110. Receiving the images of the (121, 122) through the communication network 130 receives the DVR 120 for providing the image and detection information to the remote control server 125, and receives the information provided by the DVR 120 Subscriber information is captured from the database 127 linked based on the information. And, generating a video message transmitted to the subscriber is made it to the control server 125 for transmission to one of the subscriber terminals (132, 131).

That is, the contactless access management configuration for detecting the movement of the management object in a non-contact manner and the DVR configuration for acquiring and storing images from multiple cameras and, if necessary, transmitting certain images to a remote place through a communication network, and obtained from multiple DVRs. Based on the image and the management target information, a complex combination of control configurations for transmitting a message (multimedia message, e-mail, etc.) to the subscriber who has requested the management of the management target, the related information including an access image of the management target.

Through this combination, the subscriber acquires accurate images of moving targets concentrated in a certain period of time and manages the managed targets. In order to be delivered close to, it is necessary to accurately detect a management object using a large contactless method, obtain an accurate image of a management object moving with a plurality of groups, and generate a video message suitable for various subscriber stations.

Let us look at each element of the configuration shown in the above point of view.

First, the students 141 and 142 to be managed are to carry the contactless authentication means always available, for this purpose, it is preferable that the contactless authentication means is an RFID tag with high detection speed and high accuracy without requiring power management. However, in some cases, power may be added for high detection performance. The RFID tag may be applied to a student ID card or applied to an item that the student always carries, such as a student's bag, a wristwatch, or a mobile phone. The RFID tag may store information on students, but may have only unique information of the RFID tag in order to reduce cost and improve detection performance.

Although the 900MHz band RFID tag in which standardization is in progress is suitable as the contactless authentication means, it is noted that other types of short range wireless communication methods (RF, IrDA, Bluetooth, Zigbee) may be applied. Of course, the interlocking detection means should also apply means for supporting the same communication method.

In addition, the RFID tag may not only be applied to students subject to management, but may also be applied to teachers, school staff, administrative staff, and related persons related to the school. In this case, the RFID tag may be used for simple access management without subscribers. It can be used for time and attendance management or access management.

The RFID server 110 may perform an authentication process based on the RFID tag information obtained from the RFID receivers 101 and 102 and a student and related person information database (not shown) pre-configured in and out of the RFID tag. It is possible to perform separate access management by identifying whether it is a management target who needs to acquire and transmit or a related person who needs to perform simple access management. The RFID server 110 substantially acts as an access management server, and provides related time and attendance management functions such as storage of the access information and classification by date. Subsequent access management for the management subjects includes location information (or event occurrence information) of the RFID receivers 101 and 102 and detected RFID tag information (or management target / subscriber information included in the tag). It provides a function to deliver to the DVR (120). In addition, the access information of the management subjects is separately set as access information of the management subjects using the belonging and time information (or the direction of movement of the subjects, which will be described in detail later) of the management subjects. Can provide. For example, when shown, students can manage their school's attendance and drop-off information for each class, and provide that information to their classroom teacher.

The DVR 120 may store an image of the plurality of cameras 121 and 122, a basic function of searching for a corresponding image, and an image obtained at a certain time, or an image corresponding to some of the plurality of cameras. By extracting a series of images before and after the view point, the image and one or more pieces of detection information (RFID tag information, management target / subscriber information included in the RFID tag, time information, and part of the DVR information) acquired from the remote view It has a function of transmitting to the control server (125). To this end, the DVR 120 is provided with a remote access function through the communication network 130, it may be provided with a subscriber network access means such as a web server.

The communication network 130 includes various communication networks such as an internet network (TCP / IP), a wired communication network (PSTN), a wireless communication network (WLAN, WAP, etc.), an information communication network (ISDN), and the like.

The control server 125 receives image information and detection information provided from the plurality of DVRs 120 and applies the characteristics of the corresponding terminal to the subscriber terminals 132 and 131 set by the subscriber who has requested management of the management target. Performs the function of creating and providing a video message of a suitable type. In addition, the control server 125 may select a suitable optimum image (images in which all of the management objects corresponding to the plurality of detection information simultaneously transmitted) are selected from among the corresponding images when a series of images is received; In order to transform the screened image into an image suitable for each subscriber station corresponding to the management targets, the image provided by the DVR is changed in size to suit the display characteristics of the subscriber station and post-processing (sharpening, contrast). Increase, auto-correct, etc.). For example, when the subscriber station 132 is a mobile communication terminal (mobile phone, personal digital assistant, etc.), the subscriber terminal 132 generates a multimedia message having an image of a size that the terminal can receive and display. When the terminal 131 is a PC having a communication function, the terminal 131 may generate and provide an e-mail message including a high quality image for capacity.

The illustrated database 127 may be accessed by the control server 125 and may be stored in association with subscriber information and information on a management target. If necessary, the database 127 may have a server function to provide database information to the RFID server 110, and process subscriber access through the communication network 130 to obtain subscriber information and management target information. It may be. Of course, such a web server function may be provided by the control server 125.

In addition, the database 127 stores the image and detection information (time information, detection type (school / school), DVR location (school name), etc.) provided to the subscriber by the control server 125 to separate subscribers. In case of direct connection, the video may be provided. In this case, the video may be an original video provided by the DVR.

FIG. 4 is a view illustrating a divisional configuration of the RFID receivers 103a to 103d and the cameras 121a to 121d and 122a to 122d for more precisely obtaining an image of a management target. If there is an entrance and exit, the appropriate detection area and image acquisition area are divided into unit zones (A ~ D), and RFID receivers 103a to 103d in charge of the corresponding zones are disposed in each zone, and the management target passing through the zones. The camera pairs 121a-122a, 121b-122b, 121c-122c, and 121d-122d are disposed at positions where the front surface can be photographed according to the progress direction of the corresponding management targets. Through the arrangement as described above, the RFID server can know the position information and the RFID tag information of the RFID receiver (specific information allocation for each RFID) that detects the RFID tag. Therefore, it is possible to provide the DVR with information for selecting a camera suitable for the detected contents. In addition, since the RFID server can know the arrangement position of the cameras and the arrangement information of the zone, it is possible to adjust the time of providing the information to the DVR at the time of RFID tag detection in consideration of the general moving speed of the management object. You can also manage the time of acquisition.

On the other hand, in the case of the management target detected at a time other than the period that can be distinguished, such as school or dismissal, it is difficult to know the exact direction of movement, it is possible to arrange a plurality of RFID receivers for the progress.

FIG. 5 illustrates a case in which RFID receivers 101a, 101b, 102a, and 102b are overlapped with each other in a traveling direction so as to know the exact moving direction and the moving speed of the management targets 141 and 142. FIG. When the respective detection areas E and F are set on the rear surface and the rear surface, the moving direction of the management targets 141 and 142 can be confirmed through the detection of a continuous RFID tag, and the speed thereof can also be calculated. Accordingly, the RFDI server that has obtained the information may provide information (for example, event information) that allows the DVR to acquire an image of an appropriate viewpoint using an appropriate camera in consideration of the moving direction information and the moving speed. Of course, the DVR may be provided with the above-described functions. In this case, the RFID server only needs to transmit detection information and detection generation position information of the RFID tag to the DVR.

6 illustrates an example of a screen of a subscriber station 132 that has received a video message provided by applying the above schemes, wherein the subscriber station 132 in the form of a mobile communication terminal receives image information and detection in a multimedia message format. It is a screen 133 for receiving and displaying related information (name of management subject, whether to go to school or not, whether to go to school or not, time information, etc.).

In this way, subscribers can visually check when their child enters and exits school, who attends with them, how their child feels, and what local weather is like.

FIG. 7 illustrates a configuration of an embodiment in which the above-described configurations are expanded, and as illustrated, a plurality of local systems 200, 210, and 220 configured as a plurality of contactless access management means and a DVR means capable of detecting and transmitting images. The configuration of the control server 240 for the integrated management of the image and the detection-related information provided by the subscriber terminal (231, 232, 233) and the subscriber management to receive the image containing message generated by the control server 240 and A combination of configurations (database 245, dynamic domain name server (DDNS) 250) for supporting connection of communication network 230 of multiple DVRs 205, 215, 225 is shown.

In general, the local systems 200, 210, and 220 for providing the subscribers with access information on a plurality of managed objects in a video form a unit configuration of individual schools, academies, factories, and workplaces, respectively. Fields (images, detection related information) are managed by one or more control server 240 in the form of multimedia messages (short messages in special cases) or e-mail messages according to the types of subscriber stations (231, 232, 233) The video message is generated and provided to each subscriber station.

In general, the DVRs 205, 215, and 225 may have a fixed IP address, but in many cases, the DVRs 205, 215, and 225 are likely to be used in an environment in which IPs are dynamically assigned. Even if the IP of the DVRs 205, 215, and 225 is changed by registering 215 and 225, the control server 240 provides the IP information of the DVRs 205, 215, and 225 to connect as if using a fixed IP. To be able. In addition, the DDNS 250 can perform the registration and authentication process for the subscribers as well as the information on the IP to obtain the necessary subscription information and can be connected to the control server 240 with the database 245 It can be stored in the, the control server 240 may provide the subscriber with the subscriber-specific image or detection-related information stored in the database 245 through the authentication process. That is, through this process, the subscriber's subscription, subscriber information acquisition, and subscriber authentication can be handled and billing can be handled if necessary.

8 shows an example of an image format provided by a DVR to a control server. As shown in FIG. 8, the image is composed of a plurality of frames. The DVR may not simply select and transmit one of the images obtained through a specific camera based on the detection related information provided by the RFID server, but may collectively transmit a series of images before and after receiving the detection related information. . That is, since the DVR performs the function of storing the images provided from all the cameras in the built-in storage means during normal times, it is possible to extract the images before and after a specific point of view, and through such images The probability of video transmission can be reduced.

In particular, when the motion is severe, the captured image may be shaken or have low sharpness, and not all of the managed objects to be photographed may be included in the image. It is desirable to select an optimal image, and this function can be mainly performed by the control server. The series of images may be selected in the order of frames stored by the DVR, and may be selected at regular intervals in consideration of the moving speed of the management target and the position of the camera. For example, the illustrated series of images may be in a format including two images before the time point at which the detection related information is received and eight images after the detection related information.

The control server selects an optimal image based on at least some of information including sharpness, contour, color, and facial face among the received series of images. Considering the processing time and the computing power of the control server, A method to select a high-definition image, a method to detect the outline to infer the number of people and select the image with the highest number, and a color detection to detect the most color (for example, skin color) Can be applied individually or in combination to determine the number of people by analyzing the face, to determine the number of people or to select the image containing the face of the person with a high similarity to the management object.

And, if necessary, the control server can be modified in accordance with the type of the message to transmit the selected image of the image and the screen size of the subscriber station to be transmitted. In addition, the control server may make the video into a short video and include it in the video message.

In addition, the control server may further perform a function of separately storing the original of the video or the original of the selected video to provide it when the subscriber requests, or may provide a video message in a plurality of ways. That is, for example, a multimedia message may be generated and transmitted to a mobile phone, and an email message including an image may be generated and transmitted to an email address.

FIG. 9 is a flowchart illustrating a process of providing access information of a management object to a subscriber by applying the above-described system. In this case, the areas divided by a plurality of RFID receivers and cameras are distributed and disposed in a moving area of the management object. An RFID server that provides related information to a DVR uses a device having an access management function. The DVR has a function of obtaining a series of images from a camera arranged in a specific direction of a specific area through the detection-related information and transmitting them to a control server, wherein the control server selects a specific image from the series of images. It is provided with a function of providing a video message to the subscriber terminal.

First, when a management object having an RFID tag, which is a non-contact authentication means, passes a management area in which a specific RFID receiver is disposed, the RFID server receiving the sensing information may use the information as it is or in consideration of the layout information of the management area. Wait for the next sensing information and check the information on the direction (and speed) of the management target. Thereafter, the tag information included in the detected information is checked to determine whether it is a registered tag, and if it is not a registered tag, no further work is performed or only a simple access record is left if necessary.

If the detected tag is a registered tag, the RFID server records a management object corresponding to the RFID tag or related information carrying the RFID tag and separately performs an access management procedure (not shown). On the other hand, the management of the cameras arranged in the zone in consideration of the information related to the RFID tag, the information on the zone in which the RFID tag is detected, the direction and speed of movement of the management target, and the arrangement of the camera with respect to the zone The camera transmits information to the DVR at an appropriate timing to acquire an image through a camera disposed at a position where the subject's face can be checked. The direction, movement speed, camera selection, and timing selection may be performed by the DVR itself based on simple detection related information provided by the RFID server. The timing information may not necessarily be real time because the DVR may continuously store an image and extract an image captured and stored at an arbitrary point in time.

The DVR acquires an image of the management target (single or a plurality of management targets) as a series of image information, and provides various detection related information (RFID tag information and identification information of the management target corresponding to the tag) related to the management target. , The detection time information, the unique information of the DVR (corresponding to the installation location), and some of the subscriber information requested to be managed by the management target) are transmitted to the remote control server.

In practice, in a situation where a large number of managed persons pass through a certain area within a certain time, there may be a plurality of managed objects passing through the same area for a specific time interval, so that the RFID server or DVR can manage the movement speed or area of the managed objects. In consideration of the area that the camera can hold at one time, the image can be selected and transmitted at a predetermined time unit. For example, when four RFID tags are sequentially detected, the first three RFID tags are processed at one time by acquiring and transmitting one image in consideration of the detection interval, and the subsequent one RFID tag is obtained by the next image acquisition and transmission. You can apply a way to handle the transmission.

 The control server receives the images and detection-related information provided from a plurality of DVRs and selects the image to be transmitted to the appropriate optimal image among the images. In this case, the image quality of the selected image may be improved by performing image correction on sharpness, color, contrast, and the like. The control server acquires corresponding subscriber information through the detection related information (which may be information on multiple management targets), and if the subscriber is an authenticated subscriber, the type of the subscriber station and the message to be transmitted to the subscriber station. By selecting a type, a message in which the selected image is inserted is generated and transmitted.

Although not mentioned above, if the management object that does not carry the non-access authentication means by additionally applying passive access information confirmation means and method to the system manually inputs its own information into the means, the means and the information are inputted. Access authentication may be performed by acquiring an image of an input time point.

By using the above method, parents can clearly check not only their children's attendance and attendance information, but also related surrounding situations (friend group, attendance and attendance status, child's status, etc.), and the administrator can visually check the actual access information of the management subjects. This will make it clear.

As described above, the access control system and method according to an embodiment of the present invention is located at a position where the management object moves by grasping the movement and authentication information of the management object having a non-contact authentication means through a sensor receiver. By acquiring the image of the management object through a camera and transmitting it to the subscriber who requests the management object as an image, it is possible to visually check the actual identity of the management object in addition to the access information of the management object. It works.

The access control system and method according to an embodiment of the present invention provide the digital image storage device (DVR) that continuously stores the information when the management target is detected by the authentication means, and then moves the control target to the moving direction of the management target. By extracting a series of images before and after the detection target of the management target from the image information of the located camera channel and transmitting them to the control server, and selecting the most suitable image among them, it is possible to select and provide a clearer management target image. It has an effect.

When the control server receives a series of image information, the access management system and method according to an embodiment of the present invention analyzes information such as sharpness, outline, color, and facial information of the image information, and simultaneously detects a plurality of images. By allowing the user to select high-quality images including all the management targets, images for multiple management targets can be processed at one time, thereby reducing the load and effectively coping with the situation in which visitors are concentrated.
