Description

CCTV-linked access control system and method using IoT technology and RTLS}

The present invention relates to access control technology, and more specifically, Internet of Things (IoT) technology and Real Time Location (RTLS) technology that manages the movement of visitors within a facility and supports rapid evacuation of visitors in the event of an emergency such as a fire. This is about a CCTV-linked access control system and method using a system.

Current passive RFID access card-based access control security is limited to opening/locking the gateway due to the problem of not being able to provide real-time location. Because of this, RFID access card-based access control security is limited to the role of a key to simply open a door rather than the role of control and security.

This existing access control system has several problems as follows.

First, if the access key is stolen or lost, there is a problem that security personnel must use another person's access key because it is impossible to monitor them individually.

There is a problem in that the gateway is left open during rush hour or when executives, VIPs, or visitors flock there.

Additionally, once a person enters the facility, control is not possible, so there is a problem in that it is impossible to determine the indoor location.

In other words, in the past, only the entry and exit of visitors could be controlled, and the location within the facility was not identified, so there was a problem in which major facilities were not managed well.

Because location tracking tags using existing general GPS cannot track location inside a facility, there were limitations in notifying visitors of the emergency situation when an emergency situation occurred.

As a result, there was a problem in that it was not possible to prevent illegal activities by those entering the system or effectively warn people of access to dangerous areas.

Entrants are provided with a beacon 100 before passing through the entrance gate by a device or manager that manages access to the facility. The visitor receives a beacon signal from the beacon 100 provided through the visitor terminal 150, and communicates with the access management server 400 via the identifier included in the received beacon signal to receive access authorization information. .

The visitor can use the provided beacon 100 to pass through the entrance gate, move to the access authorized area, and perform necessary work.

The visitor terminal 150 is a communication terminal that receives facility interior access details input from the administrator terminal 500 from the access management server 400. The visitor terminal 150 is a communication terminal in which the identifier of the beacon 100 distributed to the visitor and the identification code of the visitor terminal 150 are previously mapped and stored in the access management server 400.

When a beacon signal is received from the beacon 100 possessed by an entrant to the access control server 400 via the beacon receiver 250, the access control server 400 identifies the entrant through the identifier of the received beacon signal. . The visitor terminal 150 can receive access authorization, alarms, warnings, etc. from the access management server 400.

After the visitor terminal 150 and the beacon 100 are linked via the identifier of the beacon 100, if the distance between the visitor terminal 150 and the beacon 100 exceeds the critical distance, the visitor terminal 150 An alarm can be output. Alternatively, the beacon 100 may notify the access control server 400 through the beacon receiver 250 that the visitor terminal 150 has deviated from the critical distance from itself. In other words, since the access management server 400 manages visitors based on the beacons 100 distributed to the visitors, if the distributed beacon 100 moves away from the visitor terminal 150, a problem occurs in which visitors cannot be managed. . Therefore, after a person enters the facility, the access management server 400 monitors whether the distance between the visitor terminal 150 and the beacon 100 is within a critical distance.

The visitor terminal 150 may be a communication terminal mapped and stored with the administrator terminal 500 in the access management server 400 to be synchronized or linked with the administrator terminal 500 in real time.

The visitor terminal 150 can input the visitor's entry location and expected time required and transmit the information to the access management server 400.

The visitor terminal 150 receives access authorization information (e.g., movement path, access authorization time, access authorization area, etc.) from the access management server 400. The visitor can then request a change in the access authorization information to the access management server 400. Changes to access authorization information may include movement route, access authorization time, access authorization area, etc. When permitting a change in access authorization information, the access management server 400 may transmit the permitted access authorization information to the visitor terminal 150. For example, if the visitor must proceed with work beyond the access authorization time, an extension of the access authorization time may be requested from the access management server 400. When the access management server 400 permits an extension of the access authorization time, the access user terminal 150 may receive the permitted access authorization time from the access management server 400.

Here, the visitor terminal 150 may include a Personal Communication System (PCS), Global System for Mobile Communications (GSM), Personal Digital Cellular (PDC), a smartphone, a smart pad, a tablet PC, etc.

Beacon receivers 250 are installed at multiple points within the facility. The beacon receiver 250 receives a beacon signal from the beacon 100 possessed by the visitor and transmits it to the access management server 400. The beacon receiver 250 may be installed in an appropriate number so that the beacon signal can be received without the beacon 100 carried by the person moving within the facility and without a shadow area.

This beacon receiver 250 may be a device that receives sensed values from at least one sensor. The beacon receiver 250 may be a device that transmits detection values to the access management server 400. When attempting to authenticate a visitor using the beacon receiver 250, it may be a device that operates the CCTV 300 at the time the signal from the beacon 100 is received to check whether the identifier and the mapped image of the visitor are correct.

CCTV 300 is installed at multiple points within the facility to film the surroundings. CCTV (300) transmits the captured video to the access control server (400). The CCTV 300 can capture visitors entering the facility under the control of the access management server 400.

The guidance message output machine 350 is installed at a plurality of points within the facility and outputs necessary guidance messages to visitors entering the facility. For example, the guidance message may include a usage guidance message on how to use the facility, a warning message about movement in an unauthorized area, an emergency situation message informing of an emergency situation, etc. The guidance message may include text, light, sound, etc. The guidance message output device may include a speaker, an alarm, a display device, etc.

The access control server 400 is a device that manages people entering and leaving the facility using IoT technology and RTLS. The access management server 400 collects beacon signals including the identifier of the beacon 100 received via the beacon receiver 150, and collects streaming or downloaded video through the CCTV 300 to determine who enters the facility. manage.

When the access management server 400 receives the beacon signal, it can transmit a visitor confirmation message to the visitor terminal 150 of the person holding the beacon 100 and receive a reply message from the visitor terminal 150. For example, the access control server 400, which has received the beacon signal, sends an accessor confirmation message to the accessor terminal 150 using the user (entrant) information of the pre-stored beacon, that is, the phone number of the accessor terminal 150. A response (reply) message can be received from the visitor terminal 150.

The access control server 400 compares the detection value received from at least one sensor with a preset reference value, and if it is outside the error range, sends a notification to the visitor terminal 150 or the guidance message output 350 to prevent an accident. Can be transmitted.

The access management server 400 can monitor the movement of visitors and produce statistics and tallies at the same time. When the access control server 400 recognizes the beacon 100 of the visitor from the beacon receiver 250 installed in the unauthorized access area, it can inform the relevant visitor terminal 150 that the access is an unauthorized area.

The access management server 400 can perform the function of monitoring the entry and exit of people entering and leaving the facility using the beacon receivers 250 installed for each authorized and unauthorized area.

This access management server 400 can be implemented as a computer that can access a remote server or terminal through the network 200. Here, the computer may include a laptop equipped with a web browser, a desktop, a laptop, a cloud, etc.

The access management server 400 manages visitors based on real-time location tracking using the beacon 100, and identifies and responds to unauthorized actions of visitors in advance, thereby suppressing problems caused by existing post-confirmation and response. You can.

First, the access management server 400 can manage visitors based on the access area.

The access management server 400 sets an authorized access area and an unauthorized access area within the facility for each visitor to whom the beacon 100 is distributed. The access management server 400 collects beacon signals output from the beacon 100 from a plurality of beacon receivers 250 installed within the facility. The access management server 400 confirms the movement path based on the location of the visitor determined by the collected beacon signal. The access management server 400 checks whether the confirmed movement path is within the access authorization area, and then, if it is within the access authorization area, estimates the direction of movement according to the confirmed movement path. In addition, if the access management server 400 estimates the direction of movement and there is a visitor approaching an unauthorized area, it outputs a warning message notifying the visitor that he or she is approaching the unauthorized area.

At this time, the access management server 400 checks the movement path based on the location of the visitor. The access management server 400 estimates the direction of movement of the visitor by referring to the travel path of the visitor and a map based on the visitor's location within the facility.

Alternatively, the access management server 400 may estimate the next movement path or movement speed based on the current movement path of the visitor. Additionally, the access management server 400 can determine whether the visitor is approaching an unauthorized access area based on the estimated movement path or movement speed.

The access control server 400 can output a warning message as follows.

As a result of estimating the direction of movement, the access management server 400, if there is an entrant approaching an unauthorized access area, outputs a warning message notifying the entrant that the entrant is approaching the unauthorized access area to the information message output device 350 near the entrant. can do.

If, as a result of estimating the direction of movement, there is an entrant approaching an unauthorized area, the access management server 400 may output a warning message notifying that the entrant is approaching the unauthorized access area to the visitor terminal 150 of the entrant.

If, as a result of estimating the direction of movement, there is an entrant approaching an unauthorized area, the access management server 400 may photograph the entrant using the CCTV 300 near the entrant.

Next, the access management server 400 can manage visitors based on access time.

First, the access management server 400 can set the access authorization time for each visitor to whom the beacon is distributed. The access management server 400 collects beacon signals from a plurality of beacon receivers 250 and confirms the current location and current time of the visitor. The access management server 400 calculates the travel time from the confirmed current location to the access gate. Additionally, the access management server 400 can output a guidance message to the visitor terminal 150 of the relevant visitor by referring to the calculated travel time and access authorization time.

Here, the reason why the access management server 400 calculates the travel time from the current location of the visitor to the entrance gate is to prevent the visitor from staying in the facility beyond the access authorization time.

Therefore, the access management server 400 calculates the travel time from the current location of the visitor to the entrance gate. Travel time can be calculated based on the time the visitor spent moving within the facility. The access management server 400 determines whether the difference between the calculated travel time and the access authorization time reaches the standard value. When the reference value is reached, the access management server 400 outputs a wife message to the visitor terminal 150 of the relevant visitor.

Since there may be a difference between the calculated travel time and the actual travel time of the visitor, the reference value is a time set by taking this difference into account. The standard value may be set considering the size of the facility, travel distance, etc., and may be, for example, a time of less than 30 minutes.

The guidance message may include the access authorization time, the location of the available access gates based on the current location, the travel route to the access gate, and the travel time. Other information messages may include information on how to use transportation, such as a shuttle, within the facility.

On the other hand, the access management server 400 can manage visitors as follows when an emergency situation occurs within the facility. That is, the access management server 400 confirms the current location of the visitor using beacon signals collected from a plurality of beacon receivers 250. The access management server 400 extracts available access gates from the confirmed current location. And the access management server 400 guides the movement route to the access gate extracted by the access terminal 150 owned by the access person. Additionally, the access management server 400 can notify the occurrence of an emergency situation to the information message output device 350 near the visitor.

The administrator terminal 500 is a communication terminal used by an administrator who performs access control. The administrator terminal 500 may be a terminal that transmits the movement line of the visitor to the access management server 400 and outputs it from each visitor terminal 150. The administrator terminal 500 can determine the status of an intruder from the CCTV 300 through the access management server 400 or the location of the intruder through the beacon receiver 250. When an emergency situation is detected from at least one sensor through the access management server 400, the administrator terminal 500 can immediately send an alarm.

The administrator terminal 500 may be implemented as a communication terminal capable of accessing a remote server or terminal through the network 200. This administrator terminal 500 may include a set-top box, a laptop equipped with a web browser, a desktop, a laptop, etc.

Alternatively, the administrator terminal 500 may be a communication terminal carried by the administrator that can connect to a remote server or terminal through the network 200. This manager terminal 500 may include a PCS, GSM, PDC, smartphone, smart pad, tablet PC, etc.

Figure 3 is a schematic diagram of the access control server in the CCTV-linked access control system using IoT technology and RTLS according to the present invention.

Referring to Figures 1 to 3, the access control server 400 according to the present invention includes a beacon collection unit 410, a CCTV monitoring unit 420, a moving object management unit 430, an unauthorized entry detection unit 440, and a notification unit. It may include a unit 450 and an access management unit 460.

The beacon collection unit 410 is installed at a preset location and can collect data on people entering and leaving at least one beacon 100 through the beacon receiver 250 that receives a beacon signal from at least one beacon 100.

The preset location may include an access gate that separates each area, an authorized access area, and an unauthorized access area. Among preset locations, unauthorized access areas may be mapped and stored in advance on the access management server 400. The access management report 400 can manage the entry by classifying which visitors or administrators have entered the unauthorized area.

The CCTV monitoring unit 420 can capture a visitor holding a beacon 100 that outputs a beacon signal received from the beacon collector 250 through the CCTV 300 and monitor the captured video data.

CCTV 300 is capable of real-time filming. However, since problems may arise where the load on networking resources and computing resources that analyze the CCTV (300) increases, the CCTV (300) requires the beacon collector (250) linked to the CCTV (300) to collect the beacon (100). It may operate in such a way that it is activated only when an entrant is detected or a preset image template is detected. CCTV 300 can continuously capture unauthorized access areas.

The moving object management unit 430 can determine the movement path and entry/exit of the detected object based on the collected beacon 100 data and video data of the CCTV 300. At this time, the detected object may be an entrant, an administrator, an intruder, etc.

The moving object management unit 430 is also responsible for managing the real-time location of visitors, identifying the movements of visitors on a specific date and at a specific time, and comparing and searching the movements of multiple visitors.

The unauthorized entry detection unit 440 may transmit a notification to the administrator terminal 500 when at least one detected object to which the beacon 100 is not attached is extracted from the image collected through the CCTV 300. The unauthorized entry detection unit 440 may send a notification to the administrator terminal 500 when a detected object is extracted from the video of the CCTV 300 captured in an unauthorized area.

When the signal of the beacon 100 is received from the beacon receiver 250 installed in an unauthorized area among the preset locations, the notification unit 450 detects the object attached to the beacon 100 and enters the visitor terminal 150 held by the beacon receiver 250. You can first notify that you have entered an unauthorized area. The notification unit 450 may output a warning message to the information message output device 350.

The notification unit 450 may transmit an alarm alert when the beacon 100 moves outside the center, i.e., to a non-communication area, other than an unauthorized access area, when the beacon 100 is left unattended, or when an entrant uses the emergency button.

The notification unit 450 promptly notifies the person holding the beacon 100 even if an emergency situation such as a fire occurs in an authorized access area rather than an unauthorized access area.

If an alarm is initially sent to the visitor terminal 150 indicating that an unauthorized access area has been entered, but there is no response, the notification unit 450 may regard the situation as an emergency and transmit this situation to the administrator terminal 500.

The manager terminal 500, which has received this non-response situation, can transmit it to the field security terminal (see 700 in FIG. 4).

The on-site security terminal can directly find entrants who have entered an unauthorized area through on-site security personnel, notify them that they have entered an unauthorized area or an emergency situation such as a fire, and guide them to move to an authorized access area or a safe area.

The access management unit 460 may check the identifier mapped to the collected beacon signal when determining the entrance, exit and real-time location of the detected object based on the collected at least one beacon signal and the image data of the CCTV 300.

In the case of the beacon 100, the entry and exit of the visitor can be recorded.

Figure 4 is a diagram schematically showing the operation configuration of the access control system when a person enters the facility in the CCTV-linked access control system using IoT technology and RTLS according to the present invention.

Referring to FIG. 4, the access control system according to the present invention distributes beacons 100 to visitors entering the facility 600. That is, the visitor is provided with a beacon 100 before passing through the entrance gate by the device or manager that manages access to the facility.

When a visitor enters the access authorization area 610, the visitor management server 400 continues to check the travel path of the visitor through the beacon collector 250 and CCTV 300.

The visitor management server 400 estimates the direction of movement according to the confirmed movement path, and if there is an entrant approaching the unauthorized access area 620 as a result of estimating the direction of movement, the visitor is close to the unauthorized access area 620. A warning message is output informing you of this. For example, a warning message may be transmitted to the visitor terminal 150 of the relevant visitor.

When an entrant enters the unauthorized access area 620 without entering the authorized access area 610, the CCTV 300 photographs the movement path of the entrant and transmits it to the access management server 400.

When an entrant enters the unauthorized access area 620, the access management server 400 secondarily notifies the entrant's entry terminal 150 that the entrant has entered the unauthorized access area 620. At this time, the warning message secondarily notified to the visitor terminal 150 may include text, warning sound, or vibration.

Additionally, the access management server 400 can output a secondary warning message through the information message output device 350 near the relevant visitor.

If the visitor does not respond even though the user is notified of entering the unauthorized access area 620 in this way, the access management server 400 notifies the administrator terminal 500 of this non-response situation.

The manager terminal 500 transmits the received emergency situation to the on-site security terminal 700 so that the visitor 100 who has entered the unauthorized access area 620 within the facility 600 can be contacted directly.

An on-site security agent holding an on-site security terminal (700) checks the information received on the on-site security terminal (700), finds the person entering the unauthorized access area (620), and notifies them of their entry into the unauthorized area (620). , you can be guided to move to the access authorization area 610.

The CCTV-linked access control method using IoT technology and RTLS according to the present invention will be described with reference to FIGS. 4 to 6 as follows.

Figure 5 is an operation flowchart illustrating a first example of a CCTV-linked access control method using IoT technology and RTLS according to the present invention. Figure 5 shows a method of managing visitors based on the access area.

First, in step S10, the access management server 400 sets an authorized access area 610 and an unauthorized access area 620 within the facility 600 for each visitor to whom the beacon 100 is distributed.

At this time, visitors must apply for a visit through pre-registration or on-site registration.

Entrants are provided with a beacon 100 before passing through the entrance gate by a device or manager that manages access to the facility 600. The visitor receives a beacon signal from the beacon 100 provided through the visitor terminal 150, and communicates with the access management server 400 via the identifier included in the received beacon signal to receive access authorization information. .

Entrants can use the provided beacon 100 to pass through the entrance gate and move to the access authorization area 610 to perform necessary work.

The access management server 400 performs visitor management as follows based on the beacon signal output from the beacon 100 distributed to the visitor's movement path.

Next, in step S20, the access control server 400 collects beacon signals including identifiers that distinguish visitors output from the beacon 100 from a plurality of beacon receivers 250 installed in the facility 600.

Next, in step S30, the access management server 400 confirms the movement path based on the location of the visitor determined by the collected beacon signal.

Next, in step S40, the access management server 400 checks whether the confirmed movement path is within the access authorization area 610.

If, as a result of the confirmation in step S40, the person is not within the access authorized area 610, that is, in the unauthorized access area 620, the access management server 400 informs the relevant person in step S70 that he or she is in the unauthorized access area 620. A warning message is output to notify you.

If the confirmation result of step S40 is within the access authorization area 610, the access management server 400 estimates the direction of movement of the visitor according to the confirmed movement path in step S50.

Next, in step S60, the access management server 400 determines whether there is an entrant approaching the unauthorized access area 620 as a result of estimating the direction of movement.

If there is no visitor as a result of the determination in step S60, the access management server 400 performs the process again from step S20.

If there is an entrant as a result of the determination in step S60, the access management server 400 outputs a warning message to the entrant in step S70 informing the entrant that he or she is approaching the unauthorized access area 620.

At this time, the access management server 400 may output a warning message notifying the visitor that he or she is approaching the unauthorized access area 620 to the information message output device 350 near the visitor. Alternatively, the access management server 400 may output a warning message notifying that the access control server 400 is approaching the unauthorized access area 620 to the access terminal 150 owned by the relevant access user.

The access management server 400 can use the CCTV 300 to capture visitors who are expected to move to the unauthorized access area 620.

Meanwhile, after outputting the warning message, when the relevant visitor enters the unauthorized access area 620, the access management server 400 sends the unauthorized access area 620 to the visitor terminal 150 that entered the unauthorized access area 620. ) to notify you that you have entered the system. Additionally, the access management server 400 can use CCTV 300 to capture visitors who have moved to the unauthorized access area 620.

Next, if the visitor does not respond even though the entry into the unauthorized area 620 is notified for the second time, the access management server 400 notifies the administrator terminal 500 of this non-response situation.

Next, the administrator terminal 500 transmits a message requesting on-site action to the on-site security terminal 700 so that the on-site security agent can directly visit the visitor 100 who has entered the unauthorized access area 620.

In addition, the on-site security agent holding the on-site security terminal 700 checks the message received on the on-site security terminal 700, finds the person entering the unauthorized access area 620, and determines the fact that he or she has entered the unauthorized access area 620. and can guide the user to move to the access authorization area 610.

Figure 6 is an operation flowchart for explaining a second example of a CCTV-linked access control method using IoT technology and RTLS according to the present invention. Figure 5 shows a method of managing visitors based on access authorization time.

First, in step S15, the access management server 400 sets the access authorization time for each visitor to whom the beacon 100 is distributed.

Next, in step S20, the access management server 400 collects beacon signals including identifiers that distinguish visitors output from the beacon 100 from a plurality of beacon receivers 250 installed in the facility 600.

Next, in step S35, the access management server 400 checks the current location and current time of the visitor using the collected beacon signal.

Next, in step S45, the access management server 400 calculates the travel time from the confirmed current location to the access gate.

Next, in step S65, the access management server 400 determines whether the difference between the calculated travel time and the access authorization time reaches the reference value.

If the determination in step S65 does not reach the standard value, the access management server 400 performs the process again from step S20.

If the determination result of step S65 reaches the reference value, the access management server 400 outputs a guidance message to the access terminal 150 of the relevant person in step S75. The guidance message includes information that allows the relevant person to move out of the facility 600 within the access authorization time. For example, the guidance message may include the access authorization time, the location of the available access gates based on the current location, the travel route to the access gate, and the travel time. Other information messages may include information on how to use the transportation means, such as a shuttle, in the facility 600.
