While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the invention is not intended to be limited to the particular embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The terminology used in this application is used only to describe a specific embodiment and is not intended to limit the invention. The singular expressions include plural expressions unless the context clearly dictates otherwise.

1 is a conceptual diagram of an access management system according to the present invention.

The access management system according to the present invention includes an AP (100), a mobile terminal (200), and a management server (300).

The AP 100 includes an AP control unit 110, an AP Wi-Fi communication unit 120, and an AP BT communication unit 130.

The mobile terminal 200 includes a mobile terminal control unit 210, a mobile Wi-Fi communication unit 220, and a mobile terminal BT communication unit 230.

The management server 300 may include a user management unit 310 and a door control unit 320.

An access point (AP) refers to a relay device capable of wireless communication with a wireless device using a standard communication method such as Wi-Fi.

A mobile terminal means a terminal device carried by a user, for example, a smart phone.

Since the AP and the mobile terminal each include the Wi-Fi communication unit (Wi-Fi communication unit) and the Bluetooth communication unit (BT communication unit), the mobile terminal can receive data via Wi-Fi communication using the Wi-Fi communication unit, Data can be transmitted through Bluetooth communication.

The AP and the mobile terminal of the present invention include a control unit for controlling a communication unit (Wi-Fi communication unit) and a Bluetooth communication unit (BT communication unit), respectively.

The management server 300 can exchange data with the AP 100 while communicating wirelessly or by wire.

The user management unit 310 of the management server 300 registers the BLE signal (Bluetooth signal) of the smartphone of the users and judges whether the BLE signal (Bluetooth signal) received from the AP 100 is a registered user signal do.

When the received BLE signal is a registered BLE signal (a predetermined BLE signal), the gate control unit 320 of the management server 300 sends a signal for allowing the gate to open. Signals permitting door opening may be sent directly to the door or may be sent to the door via the AP (100). The door will open the door if it receives a signal to open it.

Automatically opening the door after receiving a signal to allow the door to open is a commonly used technique in existing automatic doors, so a detailed explanation is omitted.

Also, the management server 200 may be designed to transmit a signal to the door or the AP to permit opening of the door after checking whether a predetermined Bluetooth signal has been received, but it may be designed in other ways. That is, after the management server transmits and stores a predetermined Bluetooth signal to the access point, when the access point receives the designated Bluetooth signal, the management server may be modified so that the access point transmits a signal allowing the door to be opened to the door.

As described above, Wi-Fi communication has a very wide communication range, but Bluetooth communication is more advantageous than Wi-Fi communication for application to access management systems because it is easy to set the communication coverage to about 3 m.

However, Bluetooth communication is often turned off by a user of a mobile terminal (e.g., a smart phone), and power consumption is increased when the Bluetooth communication is continuously turned on.

According to the present invention, since the Bluetooth communication is performed and the Bluetooth (BT) scan is performed only when a predefined Wi-Fi signal is sensed through Wi-Fi communication, power consumption can be reduced. An example of a predetermined Wi-Fi signal may be a MAC address of a specific AP. Even when the WiFi communication function is turned off in a mobile terminal (for example, a smart phone), the MAC address of the nearby Wi-Fi signal generating device can be scanned. Therefore, when recognizing a MAC address of a specific AP, The access management service using the Bluetooth communication when the mobile terminal approaches the location of a specific AP (a service in which a door is automatically opened when a user who is allowed to access the door approaches the door) is provided.

In the case where the mobile terminal of the present invention is a smart phone, in order for the smart phone to function as the mobile terminal of the present invention, it is preferable that an application (application program) for allowing the smart phone to operate is installed in the smart phone.

2 is an example of a flow chart of a mobile terminal operation in the present invention. The flow chart of Figure 2

When an application (application program) is executed in the mobile terminal 100, the Wi-Fi signal can be recognized in advance.

Then, when recognizing the Wi-Fi signal set in advance, it starts BLE communication (Bluetooth communication). And then transmits the designated BLE signal (Bluetooth signal). The designated BLE signal includes unique information about the user (e.g., a unique number of a smart phone, an ID, a password, and the like) so that it can be determined whether or not the user is permitted to enter or exit.

3 is an example of a flowchart of an access point operation in the present invention.

In FIG. 3, when the access point receives the designated Bluetooth signal, it sends a BLE signal directly to the door to open the door.

4 is an example of a flowchart of the management server operation in the present invention.

In FIG. 4, when a predetermined signal is sensed (received) after waiting for signal reception at the AP, a signal for controlling the doorway (a signal for allowing opening of the doorway) is transmitted.

The access management system in the present invention can be used in apartment common entrance, hospital, company, and the like.

The antenna of the AP in the present invention can effectively limit the communication coverage using a directional antenna.

If a plurality of directional antennas are installed in the AP of the present invention, the moving direction of the user can be recognized through a change in a signal received through a plurality of antennas.

Also, when entering the inside from outside, the door is opened only when the user is allowed in advance, but when leaving outside, the door may be designed to be opened regardless of whether or not the user is allowed in advance. In other words, the door can be opened by using an ultrasonic sensor, a light sensor, a button, or the like when going outside.

Also, it is possible to automatically store the access information for the user who entered and exiting through the unique information of the user smartphone which has passed through the door, to the management server. If you do this, it is advantageous for the company to automatically manage the commute, access times, and so on.

When the access management system of the present invention is used in a common entrance of an apartment, there is an advantage that access to apartment residents is facilitated.

When the access management system of the present invention is used in hospitals, only registered persons such as patients and their caregivers can be controlled to be able to enter and exit, and it can contribute to preventing the spread of infectious diseases through track and access records of the people who entered and exits.

When the employment management system of the present invention is used in an office, it is possible to prevent an outsider from entering and leaving, and it is advantageous to automatically record and manage the commute time of employees.

One embodiment of the access control method of the present invention using the access control system may include the following four steps.

(1) Step 1): the management server transmits and stores a pre-designated Bluetooth signal to the access point

(2) Step 2: If the mobile terminal reads the unique information of the access point through the Wi-Fi communication and confirms that it is a predetermined access point through the unique information, activating the Bluetooth communication function

(3) Step 3: The mobile terminal sends a pre-designated Bluetooth signal to the access point through the activated Bluetooth communication

(4) Step 4: When the access point receives the designated Bluetooth signal, the access point sends a signal to the door allowing the opening of the door

Another embodiment of the access control method of the present invention using the access control system may include the following three steps.

(1) Step 1: Activating the Bluetooth communication function when the mobile terminal reads the unique information of the access point through Wi-Fi communication and confirms that it is a predetermined access point through the unique information

(2) Step 2: The mobile terminal transmits a pre-designated Bluetooth signal to the access point through the activated Bluetooth communication

(3) Step 3: The access point transmits the received Bluetooth signal to the management server, and when the management server receives the designated Bluetooth signal, it sends a signal to the door allowing the opening of the door

Users allowed to enter and exit in the access management system can be managed for each group. For example, in the case of an apartment access control system, apartment members become a group, in the case of a company's access control system, a company employee becomes a group, and in a case of an access control system of a medical institution, .

Accordingly, when a signal for allowing the door opening is transmitted, when notifications or advertisement information are sent from the access point to the user's mobile terminal, communication connection (Bluetooth connection, Wi-Fi connection, Connection, etc.), thereby saving communication costs.

The announcement information is information on notifications to be notified to the users of the group, and the advertisement information is information to be transmitted to the user for advertisement, and also includes information on coupon issuance and the like. Since the advertisement information can be transmitted for each group (that is, the advertisement information can be transmitted only to the mobile terminal of the user corresponding to the group), the advertisement effect is maximized and it is also possible to attract new customers.
