Description

Access location classification access control system using multiple Bluetooth modules and access control method using the same The present invention relates to an access control system for distinguishing the entry and exit locations of assets or personnel using a plurality of Bluetooth modules, and more specifically, to an access control system and an access control method using the same, which enables reliable distinction of the entry and exit locations of assets or personnel even using only short-range wireless communication technology by receiving a plurality of location-based signals transmitted from a plurality of Bluetooth communication sources for managing the entry and exit or movement of assets or personnel at a scanner, and calculating the signal strength of the said location-based signals at the scanner to estimate the scanner's location. Bluetooth is a short-range communication standard first developed by Ericsson in 1994 and is widely used for the transmission of voice or data. Bluetooth has several advantages over other wireless methods. Unlike wireless LANs, Bluetooth is not sensitive to walls or obstacles, resulting in a high data transmission rate. Furthermore, since it is non-directional, there is no need to maintain a constant directionality like a TV remote control. In addition, Bluetooth offers excellent security because it transmits data across multiple frequencies. Consequently, it has become an almost essential component in modern portable electronic devices, to the point where it is actually harder to find a product that does not support Bluetooth. Among these, the greatest advantage of Bluetooth is undoubtedly its compatibility. It offers excellent compatibility between supported devices, allowing for connection through a simple procedure. Two interconnected Bluetooth devices act as a Master and a Slave, respectively, and become connected through a simple pairing process. Once paired, the two Bluetooth devices can transmit and receive voice or data. Meanwhile, door locks installed on entrances and the like are controlled by an access control device. The access control device may be integrated into a single main body with the door lock, or it may be provided in the form of a separate access management unit or access control device along with additional functions. The access control device receives pre-set authentication information from the entrant, performs authentication (i.e., determines whether the entrant is authorized), and opens the door only to the entrant who has successfully authenticated it. To this end, the access control device may pre-register and store authentication information for authorized entrants, or it may be connected via a network to a separate server that manages such authentication information. When connected to a server, the server may perform the authentication process instead of the access control device. In such cases, the access control device may provide the authentication information received from the entrant to the server, and the server may perform the authentication process and provide only the authentication result to the access control device. Here, authentication methods that can be used for access authentication include (1) a method of receiving a password by operating a button or by using a magnetic card, RFID (Radio Frequency Identification), etc., and comparing it with a registered password, and (2) a method of obtaining images such as fingerprints, irises, veins, and faces from an accessor to extract feature points and comparing them with pre-registered feature points (i.e., registered authentication information). For example, an access control device using fingerprint authentication is equipped with a fingerprint sensor to read the fingerprint of an accessor. Meanwhile, with the recent increase in the use of multi-functional digital terminals equipped with Bluetooth interfaces (e.g., smartphones), there are attempts to utilize Bluetooth for access authentication. When an access control device needs to authenticate multiple entrants, it must always remain in a standby state for new entrants. Therefore, once the access control device has paired with a specific entrant and completed the authentication process, it must immediately disconnect from that entrant and wait for another entrant. In such cases, the fact that the Bluetooth interface allows connection up to a certain distance but lacks directionality becomes a problem. The access control device must allow Bluetooth pairing with the entrant (i.e., their smartphone) at any time if the entrant is outside the door. This is because the entrant may still be outside even immediately after the door has been opened through authentication. Conversely, the device can attempt Bluetooth pairing again with an entrant (i.e., their smartphone) who has just entered the house through authentication and is located inside, and perform authentication again. This process can occur without the entrant's know
