Description

TECHNICAL FIELD The present invention relates to an automatic gate authentication system using a smart device wireless communication and a parabolic antenna,

The present invention relates to a system and a method for automatically authenticating a gate using a smart device wireless communication and a parabola antenna, and more particularly, to a system and method for automatically authenticating a gate provided to allow access authentication of a user only by having a smart device .

Access security gates have been mainly used in public organizations and large corporations. Recently, the necessity of access security has been strengthened, and they are installed in various places such as schools, broadcasting stations, and research institutes.

Access security gates are mainly composed of physical methods such as password input and keys, and methods using short range communication and biometric technology such as RFID, fingerprint recognition and barcode recognition.

However, in the case of the short distance communication and the biometric method, the passenger has to prepare the card and touch the finger, or to recognize the fingerprint, so that the speed of the physical method is faster than that of the past.

Korean Patent Laid-Open Publication No. 2016-0062369 (published on June 2, 2016) discloses an access authentication system and an authentication method using Bluetooth and a smart device.

It is significant that the wireless communication method solves the inconvenience of the passengers by performing the security authentication only by the user having the smart device.

However, a number of patent documents including the above prior art do not provide a solution to the following several problems.

First, the smart device owned by the user is normally in the standby mode. In standby mode, it does not scan the signal sent from the wireless communication module. Therefore, it is necessary to release the standby mode of the smart device when the user passes through the gate, or to load the application continuously in the background. To release the standby mode directly by the user is against the intention of solving the inconvenience of the passengers, and always loading the application causes problems of battery consumption and memory occupation.

Second, when the smart device searches for the MAC address of the gate, the authentication request is made to the server. However, there is a problem that the authentication data is excessively accumulated in the server due to the authentication request of several times per second, which makes it difficult to select valid data.

Third, when the reception intensity of the wireless transmission signal is detected in the smart device, there is a problem that the difference in value is not clearly distinguished according to the distance between the smart device and the wireless communication module, and the value is irregularly generated.

Fourth, when the user passes through the gate while holding the smart device, the gate is not opened in real time due to the time required for the authentication request of the smart device and the authentication process of the server, .

Hereinafter, the present invention will be described in detail with reference to the drawings. The embodiments described below are provided as examples for allowing a person skilled in the art to sufficiently convey the ideas of the present invention. The present invention is not limited to the embodiments described below and may be embodied in other forms.

The gate automatic authentication system according to the present embodiment is provided to enable an authenticated user to pass through the gate by having a smart phone.

To this end, the present gate automatic authentication system is configured to include the gate 100, the smart device 200, and the server 300.

The gate 100 is responsible for access control and is designed to allow unauthorized, unidentified users to pass only controlled and authenticated users. To this end, the gate 100 is configured to include a proximity sensor 110, a gate wireless communication module 120, a controller 130, an access unit 140, and a parabolic antenna 150.

The proximity sensor 110 is provided for recognizing the user when the user enters a predetermined area in the gate. In order to recognize the user, the proximity sensor 110 may be provided with an infrared sensor

When the proximity sensor 110 senses the user and generates an electric signal, power is applied to the gate wireless communication module 120 and the gate wireless communication module 130 operates.

Of course, the proximity sensor 110 may be provided with an ultrasonic sensor. Ultrasonic sensors are advantageous in that they are not affected by external factors such as the color and temperature of the object. However, the ultrasonic sensor may have a problem in that the speed of signal recognition is lowered due to the relatively slow speed due to the sound waves. If the user can be detected, a sensing device other than an infrared sensor and an ultrasonic sensor may be provided.

The gate wireless communication module 120 is provided for outputting an access signal to the smart device 200. The access signal may include the identity information of the corresponding gate.

For example, a plurality of gates may be provided to allow an authenticated user to pass through, and each gate may have different identity information. In this case, the ID information of the gate 100 may be included in the access signal so that only the gate 100 through which the user passes is opened.

Incidentally, the ID information is unique information that can identify the gate such as the Mac address of the gate.

As a result, the server 300 receiving the authentication request signal including the ID information may send an operation control signal to the gate 100 accessed by the user, so that only the gate 100 accessed by the user is opened. The server 300 will be described later in more detail.

The control unit 130 is provided for controlling the first half of the gate 100. For example, when the proximity sensor 110 senses a user and generates an electrical signal, power is applied to the gate wireless communication module 120, and the gate wireless communication module 130 outputs an access signal.

Here, the access signal serves as an event signal for driving a dedicated application of the smart device 200. This allows authentication to be performed even if the dedicated application is not always loaded in the background.

In addition, when the operation control signal is received from the server 300, the control unit 130 may open the access unit 140 so that the user can pass the operation control signal.

The access portion 140 is provided for opening and closing the gate to limit access of the user. For example, it is possible to restrict the access of the user by installing an access door. When the operation control signal is received from the server 300, the motor provided with the access film may be operated to open the access film.

On the other hand, the parabolic antenna 150 is provided to clearly distinguish the access signal within the recognition range from the access signal outside the recognition range.

For example, if the access signal within the recognition range of the smart wireless communication module 220 is class A and the signal outside the recognition range is class B, the signal intensity that is the boundary between class A and class B becomes a threshold value.

Since the intensity of the signal varies depending on the location and the environment, the threshold value can not be specified as one and thus it is impossible to automate the threshold setting. Nevertheless, the thresholds in the situation are clearly defined according to the location and the environment, so that other protocols using the same frequency band and the gates caused by radio interference due to interference propagation (multipath) received by surrounding objects or walls It is possible to prevent an operation error of the portable terminal 100.

Specifically, there are a software method and a hardware method for classifying a class A and a class B by giving a threshold value.

First, in software, a correction algorithm such as Kalman filter is applied to remove the noise of the signal. The Kalman filter is applied and the signal intensity of the recognition range is set as a threshold value by directly measuring the signal at a position within or outside the recognition range. Referring to FIG. 6, there is shown an example in which noise of a signal is removed by applying a Kalman filter. ? represents a signal before filter application, and? represents a signal after filter application.

Second, it is possible to amplify the signal intensity within the recognition range by using the parabola antenna 150 in a hardware manner, and to derive the threshold value by attenuating the signal intensity outside the recognition range.

As described in the background of the present invention, there is a problem in that when the reception strength of the access signal of the gate wireless communication module 120 is detected, the difference in value is not clearly distinguished and the value jumps irregularly. To this end, the present invention can improve the accuracy of recognition by concentrating signals using the parabolic antenna 150. [

Referring to FIG. 7, a propagation source is positioned at the center of the parabolic antenna 150 so that the signal is reflected. Since the gate wireless communication module 120 corresponds to a radio wave source, it can be mounted at the center of the parabola antenna 150. [ The concave surface of the parabolic antenna 150 may be disposed so as to face the direction in which the user passes, and the gate wireless communication module 120 may be disposed at a position corresponding to the concave surface. Accordingly, the smart wireless communication module 220 receives the reflected signal on the concave surface of the parabolic antenna 150. [

As described above, when the reception intensity of the access signal is sensed in the smart device 200, the difference in value is not clearly distinguished according to the distance between the smart device 200 and the gate wireless communication module 120, There is a problem that a splash phenomenon occurs. The parabola antenna 150 of the present invention clearly distinguishes signals within and outside the recognition range.

The smart device 200 is provided to receive an access signal from the gate 100 and authenticate access to the smart device 200 by requesting authentication from the server 300.

To this end, the smart device 200 is configured to include a smart wireless communication module 210, a control unit 220, an authentication request restriction module 230, and a display unit 240.

The smart wireless communication module 210 generates Received Signal Strength Indication (RSSI) data and transmits an authentication request signal including ID information of the gate 100, RSSI data, unique number information of the smart device 200, And is provided for transmitting to the server 300.

The RSSI data is an index of received signal strength and can be used to determine the relative distance to the communicating module (RSSI = -10n log d + Tx Power (n is the loss)).

Accordingly, the Tx Power of the gate wireless communication module 120 is determined by the distance between the smart device 200 and the gate wireless communication module 120 as well as the distance between the smart wireless communication module 210 of the smart device 200 RSSI data will be affected.

When the smart wireless communication module 210 scans the access signal, it can generate RSSI data and cause the smart device 200 to execute a dedicated application. When the dedicated application is executed, the authentication request signal may be transmitted to the server 300 so that authentication of the user is performed.

The RSSI data can be used to identify the gate 100 at the location where access authentication is desired. For example, among the access signals received from the plurality of gates 100 to the smart device 200, the gate 100 having the strongest RSSI data value may be determined as the gate 100 to which the user intends to enter / . That is, an access signal can be received by selecting a MAC address having the largest RSSI data value.

On the other hand, when a user directly drives an application for an authentication request as in the prior art, it is against the intention of solving the inconvenience of a passenger, and always loading the dedicated application in the background causes problems such as battery consumption and memory occupation .

The access signal through the smart wireless communication module 210 serves as an event signal for driving a dedicated application, so that access authentication can be performed only by the user having the smart device 200 and accessing the gate.

The control unit 220 is provided for controlling the entirety of the smart device 200. For example, when the identification information is input to the display unit 240, the identification information of the user can be transmitted to the server 300.

In addition, when the access signal is scanned by the smart wireless communication module 210, the control unit 220 drives a dedicated application and transmits an authentication request signal including the identity information of the user to the server 300. [

The authentication request limiting module 230 is provided for requesting authentication to the server 300 only when the RSSI data value of the access signal scanned by the smart wireless communication module 210 is greater than a predetermined value.

When the smart device 200 scans an access signal including the ID information of the gate 100, the smart device 200 makes an authentication request to the server 300. When authentication requests are made to the server 300 by too many authentication requests per second, There is a problem that it is difficult to pick up the valid data by piled up. To this end, the authentication request limiting module 230 of the present invention requests the server 300 for authentication only when the RSSI data value is equal to or greater than a predetermined value, thereby solving the server overloading problem. That is, the smart device 200 may be configured to transmit an authentication request signal to the server 300 only when the intensity of the access signal recognized by the smart device 200 is equal to or greater than a predetermined intensity.

The display unit 240 is provided for receiving information that can prove the identity of the user and an ID and a password to be used by the user. To this end, the display unit may include an identity registration area 241. [ 4 (a), when the user clicks or touches the identity registration area 241, the display unit 240 displays the name, resident registration number, ID, or password as shown in FIG. 4 (b) Lt; / RTI >

The inputted identity information through this process can be transmitted to the server 300 for access authentication.

On the other hand, the server 300 is provided to receive the authentication request signal and to control the gate 100 so that a user permitted to pass through the gate 100 is allowed to pass.

To this end, the server 300 is configured to include a communication module 310, an identity information registration module 320, a control unit 330, an access log recording module 340, and an output unit 350.

The communication module 310 is provided for wireless communication with the gate wireless communication module 120 or the smart wireless communication module 210.

For example, the communication module 310 may receive an authentication request signal from the smart wireless communication module 210 and may transmit an operation control signal to the gate wireless communication module 120 when the user authentication is completed.

The identity information registration module 320 is provided for storing the identification information including the unique ID and password used by the user, the unique number information of the smart device 200, and the like.

The identity information of the user input to the smart device 200 and the unique number information of the smart device 200 may be transmitted to the server 300 and stored in the identity information registration module 230.

The control unit 330 compares the identity information received from the smart wireless communication module 210 of the smart device 200 requesting authentication with the identity information previously stored by the identity information registration module to determine whether the user is permitted to enter or leave It is prepared to carry out the identification process.

When the identity information received from the smart device 200 is compared with the identity information stored in the identity information registration module 330, if the same identity information is present, it is determined that the user is permitted to enter and leave, 100 in accordance with the present invention.

However, when the smart device 200 is reported as lost by the user, the control unit 330 may restrict the authentication of the smart device 200 corresponding to the unique number information stored in the identity information registration module 320.

Through the control unit 330, it is possible to carry out the user authentication by performing the identity verification procedure.

The access log recording module 340 is provided to store and manage the identity information of the user who enters and exits, the ID information of the gate 100, and the access date and time. The access log recording module 340 enables the administrator to check and manage the entry and exit details.

The output unit 350 is provided for outputting the entry and exit details stored in the access log recording module 340. For example, the output unit 350 may include an identity region 351, a gate number region 352, and a time region 353, as shown in FIG.

The identity area 351 may be provided to output the name of the user, and the gate number area 352 may output the identity information to identify the gate 100.

Further, the time zone 353 may be provided such that the gate open time is output.

This allows the administrator to check and manage the user's access history.

8 is a flowchart illustrating a method for automatically authenticating a gate according to an embodiment of the present invention.

As described above, the proximity sensor 110 provided in the gate 100 may operate (S810). The proximity sensor 110 may be arranged to recognize a user approaching the gate 100.

If the user is recognized by the proximity sensor 110 (S820-Yes), the gate wireless communication module 120 can output the access signal (S830). The smart device 200 receiving the access signal can receive the access signal Can be driven. On the other hand, if the proximity sensor 110 does not recognize the user, the access signal is not output (S820-No).

When the dedicated application is activated, the smart device 200 can transmit an authentication request signal to the server 300 (S850). When the server 300 receives the authentication request signal including the identity information of the user, the server 300 can determine whether or not the user is permitted to access the server 300.

If it is determined that the user is allowed to enter or leave the server 300, the server 300 may be controlled to open the gate 100 (S860). The open gate may be closed after a predetermined delay time. The process of determining whether or not to permit access will be described in more detail with reference to FIG.

This allows the user to perform access authentication without releasing the standby mode of the smart device 200 or having the dedicated application always running in the background.

9 is a flowchart illustrating an access authentication process according to an embodiment of the present invention.

As described above, the proximity sensor 110 may operate to recognize the user (S905). If the user enters the gate 100 and the proximity sensor 110 recognizes the user (S910-Yes), the proximity sensor 110 may generate an electrical signal (S915).

On the other hand, if the user is not recognized, no electrical signal is generated (S910-No).

When the proximity sensor 110 generates an electrical signal, the controller 130 may apply power to the gate wireless communication module 120 (S920). When the power is applied to the gate wireless communication module 120, the controller 130 controls the gate wireless communication module 120 to output an access signal including the ID information (S925).

When the gate wireless communication module 120 outputs an access signal, the smart wireless communication module 210 of the smart device 200 possessed by the user can scan the access signal and generate RSSI data according to the intensity of the signal .

In this case, when an access signal is output from the different gate 100, the smart wireless communication module 210 scans the access signal having the largest RSSI data value (S930) It can be judged.

When the access signal is scanned, the smart device 200 can start the dedicated application (S935). When the dedicated application is activated, the authentication request signal including the identity information of the user, the unique number information of the smart device 200, and the ID information of the gate 100 may be transmitted to the server 300 (S940).

When the same identity information is present (S945-Yes), the server 300 compares the received user identification information with the stored stored identification information and determines whether the gate 100 (S950). ≪ / RTI >

On the other hand, when the same identity information does not exist (S945-No), it is determined that the user is not permitted to enter and leave, and the operation control signal is not transmitted to the gate 100. [ Incidentally, the gate 100 may be provided to generate a warning sound.

When the gate 100 receives the operation control signal, it may open the gate 100 so that the user can pass it (S955).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
