[0026] The present invention relates to an access control system having a crisis management function that automatically changes a user's access authority. Specifically, the purpose of the invention is to provide a technology that enhances security and enables response to crisis situations by automatically raising or lowering the security level of an access door when a crisis occurs, such as the intrusion of an unauthorized visitor, detection of hazardous materials, occurrence of a security incident, or occurrence of an emergency, and by restricting access by comparing the security level of the access door with the security level of the visitor.

[0027] In the following, a more detailed description of the present invention will be provided with reference to the attached drawings, and multiple drawings may be simultaneously referenced to explain one or more technical features or components constituting the invention.

[0028] Looking schematically at the drawings attached as a description of the present invention, FIG. 1 shows a configuration diagram of an access control system having a crisis management function that automatically changes a user's access authority according to one embodiment of the present invention, FIG. 2 shows a flowchart of an access control system having a crisis management function that automatically changes a user's access authority, FIG. 3 shows a flowchart explaining the function of a door authority management unit, FIG. 4 and 5 show flowcharts explaining the function of adjusting the authority of a door according to the result of a crisis situation detection unit.

[0029] Meanwhile, in the following description, some components described in the drawings may be omitted or excessively enlarged or reduced in order to explain the function of each component of the present invention, but it will be understood that such illustrated components do not limit the technical features and scope of rights of the present invention.

[0030] First, referring to FIG. 1, the description of the present invention is as follows: The access control system (10, hereinafter referred to as the ‘system of the present invention’) having a crisis management function that automatically changes the user’s access authority of the present invention includes, as a main component, a user information management unit (11), an access authority management unit (12), an access authority determination unit (13), and an access control unit (14).

[0031] The user information management unit (11) functions to manage user information, including the user's identity, biometric information, authority, and security level, by registering it with the security server (20) and the user authentication means (30).

[0032] At this time, the user authentication means (30) described above is a means for storing user information that can identify the user, and one or more authentication means among biometric information such as fingerprints, iris, veins, and facial features, and access cards may be used.

[0033] In addition, it is desirable to understand that the aforementioned access card is a card that includes means capable of wirelessly transmitting data over short distances and operating in a contactless manner, such as RFID, IC chips, and NFC.

[0034] In addition, the aforementioned user information may further include personal information such as the user's name, affiliation, department, position, resident registration number, address, and contact information, and the present invention is not limited thereto.

[0035] Meanwhile, the above-described security server (20) is configured to communicate with a communication module included in the door (40), and by comparing the user information registered in the user authentication means (30) of the user passing through the door (40) with the user information registered in the security server (20), it can determine whether the user passing through the door (40) is a user registered in the security server (20).

[0036] In addition, the user information management unit (11) described above can automatically set and manage security levels according to the user's identity and authority, and can function to automatically change the security level when there is a change in the user's identity and authority, or to change the security level according to the input of a temporary security level change from an authorized administrator account.

[0037] Specifically, when there is a change in the user's status and authority, such as hiring, resignation, promotion, leave of absence, personnel transfer, or disciplinary action, it can be understood that the security level can be automatically changed through the user information management department (11) or temporarily changed through the administrator account.

[0038] For example, it can be understood that the user's security level is managed by raising the user's security level when the user is promoted, and lowering or deleting the user's security level when the user takes a leave of absence or resigns. In addition, it may be possible to raise or lower the user's security level depending on the type of change when there is a change in the user's identity and authority, and the present invention is not limited thereto.

[0039] Meanwhile, the aforementioned door access control unit (12) can function to manage the security level of the door (40).

[0040] At this time, the aforementioned door (40) can be understood as a security gate such as a speed gate, flap gate, turn gate, full height gate, or anti-static gate, and any door capable of controlling user access may be used, and the present invention is not limited thereto.

[0041] Meanwhile, the aforementioned door (40) may be provided in multiple numbers so as to be installed in areas where user access needs to be controlled, and multiple doors may be controlled individually or in an integrated manner, and the present invention is not limited thereto.

[0042] Additionally, the above-described door (40) may include a recognition device capable of recognizing the above-described user authentication means (30), and the recognition device may include devices such as a biometric device and a card reader.

[0043] Therefore, it can be understood that by recognizing the user authentication means of a user passing through the door via the aforementioned recognition device and identifying the user, the user's access authority can be determined through the configuration of the system of the present invention described below.

[0044] Meanwhile, as illustrated in FIG. 1, the above-described door access control unit (12) may include a crisis detection unit (121) and a door access control adjustment unit (122).

[0045] The crisis detection unit (121) performs the function of detecting a crisis situation occurring around the door (40) by monitoring the environmental conditions within a preset radius from the door (40) or the door (40) through a video monitoring device installed in one area of ​​the door (40).

[0046] Specifically, the crisis detection unit (121) described above includes one or more cameras among CCTV, thermal imaging cameras, and biometric cameras as a video surveillance device, and can perform the function of detecting a crisis situation by analyzing video captured by the video surveillance device, and generating a crisis occurrence signal according to the type of detected crisis situation and transmitting it to the door access control unit (122) described later.

[0047] In this case, different signals may be generated depending on the type of crisis situation.

[0048] As an embodiment of the present invention, as illustrated in FIG. 4, the crisis detection unit (121) photographs a user approaching the door through a CCTV and a biometric camera among the video surveillance devices described above, analyzes the footage to identify the user approaching the door (S211), checks whether the identified user is a user already registered in the security server (S2111), and if the identified user is not a user registered in the security server, determines that a crisis situation such as unauthorized intrusion or terrorism has occurred (S2112), generates a first crisis occurrence signal to raise the security level of the door (S2113), and transmits it to the door authority adjustment unit (S2114).

[0049] Additionally, as illustrated in FIG. 5, the crisis detection unit (121) measures the temperature of the door and a preset radius from the door through a thermal imaging camera among the video surveillance devices described above (S212), checks whether the measured temperature is above the preset temperature (S2121), and if the temperature above the preset temperature is measured, determines that a crisis situation such as a fire has occurred (S2122), and generates a second crisis occurrence signal to lower the security level of the door (S2123) and transmits it to the door authority adjustment unit (S2124).

[0050] That is, the aforementioned first crisis occurrence signal can be understood as a signal that detects the entry of an outsider not registered on the security server, such as unauthorized intrusion by a user or terrorism, and causes the security level of the entrance door to be raised (e.g., adjusted to a security level higher than the initially set security level) in order to restrict the entry of outsiders; and the aforementioned second crisis occurrence signal is preferably understood as a signal that detects a disaster situation, such as a fire, and causes the security level of the entrance door to be lowered (e.g., adjusted to a security level lower than the initially set security level or temporarily removed from the security level) to facilitate user entry for rapid evacuation.

[0051] Meanwhile, as an embodiment of the present invention, the crisis detection unit described above is described as detecting crisis situations such as unauthorized intrusion, terrorism, and fire; however, the crisis situations in the present invention may include emergency situations such as unauthorized intrusion by an unauthorized user, detection of hazardous materials, hacking, terrorism, and fire, and may also include failure of equipment constituting the system of the present invention, and natural disasters such as earthquakes, floods, and typhoons, and the present invention is not limited thereto.

[0052] In addition, as another embodiment of the present invention, the crisis detection unit described above may include sensors such as an earthquake detection sensor, a water level detection sensor, and a wind speed detection sensor in addition to a video surveillance device to perform the function of detecting crisis situations such as earthquakes, floods, and typhoons occurring around the entrance, and the present invention is not limited thereto.

[0053] Returning to Fig. 1 to continue the explanation, the door authority adjustment unit (122) performs the function of automatically raising or lowering the security level of the door (40) according to the crisis situation detected by the crisis detection unit (121) described above.

[0054] Specifically, it can be understood that when the first crisis occurrence signal described above is transmitted from the crisis detection unit (121) described above, the security level of the door (40) is raised, and when the second crisis occurrence signal is transmitted from the crisis detection unit (121), the security level of the door (40) is lowered.

[0055] Accordingly, it is desirable to understand that the crisis detection unit (121) described above detects a crisis situation, and when a crisis situation occurs, generates a crisis occurrence signal according to the type of crisis situation and transmits it to the access control unit (122), thereby controlling the user's access by adjusting the security level set on the door (40) upward or downward.

[0056] Meanwhile, the above-described access authority determination unit (12) can function to identify the security level registered in the user authentication means (30) based on user information registered in the security server (20), and to determine access authority by comparing the identified user security level with the security level set in the door (40).

[0057] Specifically, as illustrated in FIG. 6, the access authority determination unit (12) described above identifies a security level registered in a user authentication means based on user information registered in a security server and compares it with a security level set in a door (S301), checks whether the security level registered in the user authentication means is equal to or greater than the security level set in a door (S302), and if the security level registered in the user authentication means is equal to or greater than the security level set in a door, determines that the user has access authority and generates a first signal to permit the user's access (S303) and transmits it to an access control unit to be described later (S305), and if the security level registered in the user authentication means is less than the security level set in a door, determines that the user does not have access authority and generates a second signal to deny the user's access (S304) and transmits it to an access control unit (S305).

[0058] Returning to Fig. 1 to continue the explanation, the access control unit (14) described above can function to control the opening and closing of the door (40) according to the result of the access authority determination of the access authority determination unit (13) described above, thereby controlling the access of the user.

[0059] Specifically, it is preferable to understand that the access control unit (14) described above controls the opening and closing of the door (40) based on the first signal and the second signal transmitted by the access authority determination unit (13) determining the user's access authority, and when the first signal is received, the door (40) is opened to form a passageway, and when the second signal is received, the door (40) is closed to control the user's access.

[0060] Meanwhile, the aforementioned door (40) can be understood as a security gate such as a speed gate, flap gate, turn gate, full height gate, or anti-static gate, and any door capable of controlling user access can be used, and the present invention is not limited thereto.

[0061] Meanwhile, as an embodiment of the present invention, the above-described door authority management unit (12) can function to adjust the security level of the door upward or downward according to the security level stored in the door authority change means held by the manager.

[0062] At this time, when changing the security level of the door (40) through the aforementioned door authority change means, it is desirable to determine the user's access authority by prioritizing the security level changed through the door authority change means over the security level previously set in the door (40).

[0063] That is, it can be understood that if the security level changed through the door access control change means is higher than the security level previously set on the door (40), the higher security level is used as the standard, and if the security level changed through the door access control change means is lower, the user's access authority is determined based on the lower security level.

[0064] Meanwhile, the above-described means for changing the access door authority may include means for remotely changing or manually changing the access door (40), and may include, for example, an administrator account authorized to remotely communicate with the access door, an administrator terminal, and a security card for an administrator capable of manually changing the security level of the access door, a password, a key, etc., but the present invention is not limited thereto.

[0065] Meanwhile, as another embodiment of the present invention, as shown in FIG. 7, the system (10-1) of the present invention may further include an access record storage unit (15) and a user security level adjustment unit (16) in addition to a user information management unit (11), an access authority management unit (12), an access authority determination unit (13), and an access control unit (14).

[0066] First, the access record storage unit (15) described above can perform the function of storing the access record of a user entering through the door (40) in the security server (40).

[0067] At this time, the above-described access record storage unit (15) can be understood as storing access records such as a video of a user entering through the door (40), the location of the door used by the user when entering, the type of user authentication means, the user's security level, the time of entry, and the number of times of entry.

[0068] Meanwhile, the user security level adjustment unit (16) described above can perform the function of analyzing the user's access record stored in the security server (20) from the access record storage unit (15) described above to identify the user's access pattern and adjusting the user's security level based on the access pattern.

[0069] At this time, the user security level adjustment unit (16) described above can be understood to identify access patterns such as the user's access frequency, access time, access path, access authentication means, access history, and security level through the user's access records stored in the security server (20), and to adjust the user's security level according to the user's access pattern.

[0070] For example, for users with frequent entry, the security level can be raised to facilitate smooth access. Conversely, for users with irregular entry times, the security level can be lowered to require additional security measures when passing through the door, thereby enhancing security.

[0071] In addition, as another embodiment of the present invention, it may be possible to adjust the security level of the door based on the user's entry and exit patterns. For example, during times when the frequency of user entry and exit is low, the security level of the door is raised to reliably control the entry of users not registered with the security server, and during times when the frequency of user entry and exit is high, the security level of the door is lowered to simplify the door passage procedure, thereby shortening the time required for users to enter and exit and reducing the waiting time for users waiting to pass through the door. This can improve user convenience and enhance work efficiency.

[0072] Meanwhile, although not illustrated in the attached drawings, as another embodiment of the present invention, the system of the present invention may further include a warning generating unit and a maintenance unit.

[0073] The aforementioned warning generation unit can perform the function of enabling an administrator or user to respond to a crisis situation by generating a warning signal to an administrator terminal or a space where a door is installed when a crisis is detected by the aforementioned crisis detection unit, thereby notifying the occurrence of a crisis situation.

[0074] Specifically, when a first crisis occurrence signal and a second crisis occurrence signal are generated by the crisis detection unit described above, the crisis detection unit transmits the first crisis occurrence signal and the second crisis occurrence signal to the warning generation unit, and the warning generation unit receives them and transmits them to a warning device (e.g., an emergency bell, a visual alarm device, etc.) installed in a space where an administrator account, an administrator terminal, and an access door are installed, thereby notifying of the occurrence of a crisis situation.

[0075] As an example, when the aforementioned warning generating unit receives a first crisis occurrence signal and a second crisis occurrence signal from the crisis detection unit, it transmits a first warning signal and a second warning signal corresponding thereto to the manager terminal, thereby enabling the manager to check what kind of crisis situation has occurred and allowing the manager to respond quickly according to the type of crisis situation.

[0076] In addition, the aforementioned warning generating unit transmits a first warning signal and a second warning signal to a warning device (e.g., an emergency bell, a visual alarm device, etc.) installed within the space where the door is installed. Upon receiving the first warning signal and the second warning signal, the warning device emits a different notification sound or flashing signal depending on the type of warning signal, thereby notifying an administrator or user located near the door that a crisis situation has occurred. The administrator located near the door can recognize the type of crisis situation based on the type of notification sound or flashing signal and respond to the crisis situation according to the corresponding response protocol for the occurrence of the crisis situation.

[0077] On the other hand, as another embodiment of the present invention, when the warning generating unit described above transmits a first crisis occurrence signal and a second crisis occurrence signal generated by detecting a crisis situation in the crisis detection unit described above to the administrator account and administrator terminal described above, it may be possible for the administrator account and administrator terminal to remotely control the opening and closing of the door according to the received crisis occurrence signal, and it may also be possible to temporarily raise or lower the security level of the door or the user remotely, and the present invention is not limited thereto.

[0078] Meanwhile, the maintenance unit described above can be understood as performing a function to maintain the system of the present invention in an up-to-date state in preparation for dangerous situations by testing whether the system of the present invention is operating properly according to a preset cycle to maintain the stability and reliability of the system of the present invention, and by updating user information stored in a security server.

[0079] At this time, it is preferable to understand that the aforementioned maintenance unit conducts tests to verify whether the functions of the system of the present invention operate properly, such as the communication status between the security server and the door, the operating status of the door, the operating status of the video surveillance device, and whether the security level can be changed through the means for changing door authority, as a system operation test.

[0080] Hereinafter, with reference to FIGS. 2 and 3, the flow of an access control system having a crisis management function that automatically changes the user's access rights according to the present invention will be described.

[0081] Referring to FIG. 2, the system of the present invention is characterized by performing the following steps: registering and managing user information including user identity, biometric information, authority, and security level in a security server and a user authentication means (S10); managing the security level of an access door (S20); identifying the security level registered in the user authentication means registered in the security server and determining access authority by comparing the identified user security level with the security level set in the access door (S30); and controlling the opening and closing of the access door according to the result of determining access authority to control the user's access (S40).

[0082] That is, an access control system having a crisis management function that automatically changes a user's access authority according to one embodiment of the present invention can be classified into a user information management step, an access authority management step, an access authority determination step, and an access control step.

[0083] Furthermore, it is desirable to understand that the aforementioned user information management step performs the same function as the aforementioned user information management unit, the aforementioned door access authority management step performs the same function as the aforementioned door access authority management unit, the aforementioned access authority determination step performs the same function as the aforementioned door access authority determination unit, and the aforementioned access control step performs the same function as the aforementioned access control unit.
