For example, specific shapes, structures, and characteristics described herein may be implemented in another embodiment without departing from the spirit and scope of the invention in connection with one embodiment. Additionally, it should be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. Accordingly, the detailed description set forth below is not to be taken in a limiting sense, and the scope of the present invention, if properly described, is limited only by the appended claims, along with all equivalents as claimed by those claims. Like reference numbers in the drawings indicate the same or similar function throughout the various aspects.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a diagram showing a schematic configuration of a door security management system according to an embodiment of the present invention.

Referring to FIG. 1 , the door security management system 10 according to an embodiment of the present invention includes a sensor unit 100, a terminal authentication unit 200, a camera unit 300, a foreign matter removal unit 400 and security A management server 500 is included.

The sensor unit 100 is installed as a switch-type sensing device or a laser reflection type sensing device and transmits the detected opening of the door D to the security management server 500 through the network N.

At this time, the sensor unit 100 is not limited to a switch type detection device or a laser reflection type detection device, and any device capable of detecting the opening of the door D can be applied regardless of its name. .

The terminal authentication unit 200 stores information in the user terminal (C) through short-range wireless communication (eg, Bluetooth or NFC) from the user terminal (C) carried by the user (P) who has entered through the door (D). Receives the identification information of the person P who has access, and transmits the identification information of the person P who has been received to the security management server 500 through the network N.

Here, the accessor terminal C may consist of one or more, and is widely used by the general public, such as a desktop computer (PC), a notebook, a smart phone, a tablet PC, and the like. It is a broad concept meaning various types of information communication devices and multimedia devices that support wired/wireless networks, such as mobile communication terminals.

And, the network N may include, for example, wireless communication, wired communication, optical ultrasound, or a combination thereof. Body Area Network (BAN), satellite communications, cellular communications, Bluetooth, Near Field Communication (NFC), Infrared Data Association standard (IrDA), Wireless Fidelity (WiFi), and Worldwide Interoperability for Microwave access (WiMAX) will be included in the communication path. Ethernet, digital subscriber line (DSL), fiber to the home (FTTH), and plain old telephone service (POTS) are examples of wired communication that can be included in a communication network. Also, a communications network can traverse multiple network topologies and distances. For example, a communications network may include a direct connection, a personal area network (PAN), a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), or any combination thereof. In addition, it may be performed through a low power wide area network (Low Power Wide Area Network) including LoRaWAN, NB-Fi, and RPMA. However, the description of the network N is not limited to the above communication network, and any latest data communication network may be applied.

The camera unit 300, when notified by the sensor unit 100 that the opening of the door D has been detected, starts shooting and captures the face of the person P to obtain a facial image of the person P, The facial image of the entrant P is transmitted to the security management server 500 through the network N.

When a drive request is received from the security management server 500, the foreign matter removal unit 400 removes foreign substances attached to the shoes S of the person P entering the room through the door D. It is installed on the front bottom surface of (D).

The security management server 500 stores the identification information and facial images of the visitors P who are authorized for access in a database, and uses the identification information of the visitors P received from the terminal authentication unit 200 The first authentication is performed on whether or not the person P is allowed to enter, and if the corresponding identification information cannot be checked in the database as a result of the first authentication, the face image of the person P photographed by the camera unit 300 is used. Secondary authentication is performed on the person P, and when the person P is allowed to enter through the first or second authentication, the operation of the foreign matter removal unit 400 is requested.

That is, when the security management server 500 determines that the person P is allowed to enter through the primary authentication, the foreign matter removal unit 400 is immediately requested to be driven, and through the primary authentication, the foreign substance removal unit 400 is requested to operate. If it is not determined that the person is the person (P), the secondary authentication is performed immediately, and if it is determined that the person (P) is allowed to enter, the operation of the foreign matter removal unit (400) is requested, and the person (P, who is allowed to enter) If it is not determined that it is, a warning signal can be generated using a speaker installed in the room R, and at the same time, an unauthorized intrusion warning message can be transmitted to the manager terminal possessed by the manager (not shown in the drawing for convenience of explanation). .

The door security management system 10 according to an embodiment of the present invention having the configuration described above performs secondary authentication, which is image authentication, even if the primary authentication fails because a person permitted to enter does not carry a registered terminal. Since it is possible to determine that a person has been permitted to enter through this process, it is possible to prevent an error in which illegal intrusion is judged to have occurred by the person who has been permitted to enter only through the primary authentication.

In addition, it is possible to maintain the cleanliness of the building by removing foreign substances such as sand from the shoes S of people entering and exiting the building at the entry stage.
