Description

Indoor access control system and method based on QR code and beacon {Systems and methods for controlling QR code and beacon-based indoor access}

The present invention relates to an indoor access control system and method based on a QR code and a beacon.

A general access control system requires network construction (TPC/IP) between the central system and automatic switchgear, and authentication methods vary according to the security purpose of RFID, fingerprint, number key, and biometrics (face, iris, etc.) system. In a general access control system, the reader for authentication recognition is not suitable for an outdoor exposure environment, and it is difficult to grant permanent authority because the change of the determined authority is non-variable.

Looking at the prior art related to the access system, Korean Registered Patent Publication No. 10-1465201 "identification authentication and access control system using mobile phone and its method" receives biometric information necessary for identity authentication and transmits an authentication key from a mobile phone through short-range wireless communication We provide an identification authentication and access control system and method using a mobile phone that receives a control signal from the door lock control unit and operates to allow access, and Patent Registration No. 10-1414773 "How to open and close electronic door lock device" And the mobile communication terminal" is an electronic door lock using a mobile communication terminal that recognizes a part of the body and controls whether the door lock device is opened or closed by pairing with an electronic door lock device while an application installed in the mobile communication terminal is running. A method for opening and closing the device is provided. Republic of Korea Patent Publication No. 10-2014-0082949 "Access control system using NFC communication and data transmission/reception method" converts data transmitted and received using a smartphone into NFC's NDEF format and transmits the data to the smartphone It provides an access control system and data transmission/reception method using NFC communication that can be inquired.

Like the above-mentioned patents, domestic and foreign intellectual property rights related to access control systems have been investigated to exist in considerable numbers based on many different technologies. Since the method of easily querying user registration and access using is applied, there is a problem in that the reader for authentication recognition is not suitable for an outdoor exposure environment, and it is difficult to grant permanent authority because the change of the determined authority is non-variable.

In addition, the domestic access control system has a network between the central system and automatic switchgear, and the system is built through an authentication system in the form of RFID/fingerprint recognition. Authentication technologies such as number keys and RFID are used, and the first entry is automatically registered.

In the case of centralized access devices, there are various authentication methods, but most readers are connected indoors or through a wired network, and the access system is made for the same non-surface members such as residents.

Thereafter, the QR code reader terminal compares the QR code displayed on the user terminal with the plurality of issued QR codes provided from the access control management server to confirm validity, and detects the BIA (Burned-in Address) signal of the user terminal. If so, the control unit of the first access switch is requested to open the door (S730). Thereafter, when the user terminal 200 whose validity has been confirmed calculates and provides real-time indoor location information based on a plurality of beacon signals disposed nearby (S740), the indoor location of the user terminal is determined to be the second indoor location within the second access space. When located within a preset distance from the access control device, the access control management server requests to open the door of the second access control device (S750), and when the access control management server confirms the valid period of access of the user terminal, the second access control management server A door open signal is output to the door opening/closing device (S760).

Prepare for network and server failures Process of periodically requesting a QR code issuance list at a pre-set time and storing and updating it in an internal DB Process of making a request, 4. Process of checking validity and making a response based on the data in the database in the access control management server, 5. If a successful response or the result of searching the internal DB is valid, the terminal searches for signals of nearby Bluetooth devices and Process of determining whether there is a BIA signal corresponding to the user identification code of the tagged QR code, 6. If the signal is detected, the door contact is finally closed to open the door, and if not detected, the QR code reader terminal displays 7. When the door is opened, the terminal transmits data indicating that the user has undergone QR code authentication to the access control management server.

In addition, the location-based authentication process is: 1. The process of measuring the latitude and longitude of the user's location using GPS, 2. The process of measuring the approximate location based on the measured latitude and longitude, 3. Through the smartphone app The process of activating the Bluetooth function of a smartphone when approaching a pre-set place, 4. For users who have passed QR code authentication, the smartphone App detects the signal strength from beacons installed in the field and proceeds with indoor positioning. Process, 5. When the user reaches a location requiring authentication, the process of requesting the door open from the smartphone App to the access control management server, 6. The access control management server checks the user's access validity period, etc. 7. The process of changing the state of the door to the open state, 7. The process of polling the status of the door and opening the door if it is in the open state, 8. The process of storing the user's access record in the database of the access control management server. there is.

Therefore, when using the present invention, when using a plurality of access control devices arranged in a specific space, the validity is checked through the QR code issued at the time of first passage, and when the remaining access control devices are accessed, the location authentication method automatically As the door is opened, there is an advantage in that it is possible to solve the inconvenience of passing through by tagging a QR code or an identification code one by one cumbersomely as in the prior art.
