The present invention relates to a door opening and closing, and more particularly to a recording medium recording a door opening and closing control system and a control method using a mobile terminal.

Recently, the door opening and closing system using a key operation, which is mainly used, has been designed to be so complicated and robust that it is almost impossible to open and close the door without the corresponding key. In addition, the structure of the key for setting and unlocking the door opening and closing system is also very complicated.

However, the door opening and closing system by a conventional key operation is easy to duplicate the key there was a problem that the stability of the security is very low. In addition, for a user who uses a plurality of door opening and closing devices by key operation, it is inconvenient to carry all the keys corresponding to each of the door opening and closing devices (for example, a general door, a car, and a desk). In addition, there were many inconveniences in managing a plurality of keys.

Also, in recent years, in the opening and closing system of the door, there is a technological development from the opening and closing method using a contact smart card to the opening and closing method using a contactless smart card. Even in the case of using a door opening and closing method using a non-contact smart card, the user must have a separate smart card, which causes inconvenience in terms of use and management.

In order to solve such inconvenience in use and management, a door opening and closing device and method using a mobile terminal have been considered. However, the conventional method using the mobile terminal can open and close the door only through the base station, and there is a problem of having to pay a separate call fee, and because the door is opened and closed after the communication through the base station takes a long time to open and close There was a problem.

In addition, the above-described conventional door opening and closing control system using a mobile terminal and a smart card had a problem of inferior security because only one authentication procedure is performed, and if the terminal and the smart card are lost, it is difficult to open and close the door.

1 is a view schematically showing the configuration of a door opening and closing control system according to an embodiment of the present invention.

According to FIG. 1, the entire system includes an RFID tag 10, a mobile terminal 30 and a door lock device 50.

The RFID tag 10 has a personal identification number embedded therein, and the unique identification number is wirelessly read by the door lock device when the RFID tag 10 enters an effective distance of a specific frequency.

The RFID tag 10 may be inserted into the integrated card or the mobile terminal 30. Herein, the mobile terminal 30 is not limited as long as it is a device capable of performing a short range wireless communication function with the door lock device 50 such as a mobile phone or a personal digital assistant (PDA). In addition, the integrated card may be a mileage card, a credit card, a transportation card, etc. issued by mobile carriers (KTF, SKT, LGT), at least one of them may be an integrated card. It may also be an identification card used by a general company or school. Of course, RFID tags can be applied to smart cards that are used a lot these days.

Here, the RFID tag 10 is preferably generated from the mobile communication company of the mobile terminal 30. It may be provided in the membership card by generating in the mobile communication company. In addition, it is mounted in the mobile terminal 30 so that the function of the key (key) for the RFID tag 10 and password generation (by the mobile terminal 30) according to the opening and closing of the door lock device 50 using one device Can be performed, thereby providing convenience to the user. In addition, the RFID tag 10 may be generated and managed by the mobile communication company so that the corresponding RFID tag 10 may be issued from any mobile communication company distributor. Thus, when the user loses the mobile phone and cannot open or close the door lock device 50, the user may open or close the door lock device 50 using the RFID tag 10 reissued from a nearby dealer. In addition, since authentication by a password can be performed by any mobile terminal 30 that can emit an infrared signal, the dealer can solve the problem caused by the loss of the mobile phone.

The mobile terminal 30 is a terminal capable of performing short-range communication for setting or unlocking the door lock device 50. As described above, the mobile terminal 30 is not limited as long as it is a device capable of short-range communication. Short-range communication includes RF communication, infrared communication, Bluetooth, and the like, and it is natural that all short-range communication developed or developed afterwards may be included. Hereinafter, the infrared communication according to a preferred embodiment of the present invention will be described as an example. Therefore, the mobile terminal 30 should be able to generate an infrared signal, and should have an infrared port to emit it. A password generated according to a user's operation can be transmitted to the door lock device 50 using an infrared port built in the mobile terminal 30. For example, in the case of a mobile phone, when a password is input using a numeric button, an infrared signal corresponding to each number of the input password is generated and emitted through the infrared port. It may be configured similarly to a remote control function of a television using a conventional infrared port.

The door lock device 50 reads and authenticates the RFID tag, performs an authentication procedure according to the password received from the mobile terminal 30, and opens and closes the door corresponding to the two authentication results.

Figure 2a is a view showing the configuration of the door lock device according to an embodiment of the present invention.

According to FIG. 2A, the door lock device 50 includes an RFID reader 51, an infrared receiver 52, a storage 53, a controller 54, a lock 55 and a speaker 56.

The RFID reader 51 is a device capable of reading and recognizing a unique identification number of the RFID tag 10. When the RFID tag 10 enters within an effective distance of the specific frequency by generating a specific frequency, the RFID tag ( 10) Read by recognizing the unique identification number stored in. The RFID reader 51 is preferably set to recognize only the RFID tag 10 located at a distance of about 1 meter. This is to prevent the unnecessary reading of the RFID tag 10. For example, when the door lock device 50 is provided at the entrance of the corridor apartment, the RFID of the person who passes through the corridor and enters another house may be read.

The infrared receiver 52 performs a function of receiving an infrared signal generated and emitted from the mobile terminal 30. The received infrared signal is recognized with a corresponding password to perform the authentication procedure. The function of recognizing the infrared signal as a password may be performed by the infrared receiver 52 itself, but may also be performed by the controller 54. When the infrared receiver 52 performs the infrared receiver 52 may include an infrared sensor for detecting an infrared signal and a signal recognition unit for reading the received infrared signal. The signal recognizer may have a frequency table corresponding to a number and a command corresponding to each frequency so as to recognize the received infrared signal as each number or another command. Therefore, the door lock device 50 may recognize the infrared signal received from the mobile terminal 30 as a password or other control command.

The storage unit 53 stores a preset at least one unique identification number and password. By using the stored unique identification number and password, the authentication of the unique identification number recognized by the RFID reader 51 and the authentication of the password recognized by the infrared receiver 52 can be performed. Therefore, the stored unique identification number serves as the first authentication number and the password serves as the second authentication number. The user can register or update a password by transmitting a control command for registering or updating a password and a password to be registered or updated by using the mobile terminal 30. In addition, although not shown in FIG. 2A, the door lock device 50 may further include a key input unit including one or more buttons (that is, a function button and a numeric button) to enable password registration or update using the key input unit. .

The controller 54 performs a function of processing the authentication of the unique identification number recognized by the RFID reader 51 and the authentication of the password recognized by the infrared receiver 52. In addition, it performs the function of controlling the unlocking according to the lock setting of the lock unit 55 and the authentication result of the unique identification number, password.

The control signal for unlocking is generated by performing authentication of the unique identification number recognized by the RFID reader 51 and authentication of the password recognized by the infrared receiver 52.

The controller 54 may automatically generate the lock setting signal when a predetermined time (for example, 3 seconds) elapses after the lock is released by the control signal for the lock setting. In addition, the lock setting signal may be generated when the unique identification number of the RFID tag 10 is recognized and authenticated by the RFID reader 51 in the unlocked state. Alternatively, the lock setting signal may be generated by the lock signal generated by the mobile terminal 30 and recognized by the infrared receiver 52. Here, the lock signal may be generated by the infrared receiver 52 recognizing an infrared signal generated by the mobile terminal 30 by pressing any button provided on the keypad.

The above-described processing procedure according to the lock setting and unlocking will be described in detail below with reference to the drawings.

The lock unit 55 is driven in response to the lock setting signal or the lock release signal transmitted from the control unit 54 to set the lock state and the unlock state of the door.

The speaker 56 performs a function of generating a warning sound when the read RFID tag 10 is not authenticated or when the password according to the received infrared signal is not authenticated. Alternatively, all authentication procedures may be performed to output a sound corresponding to the authentication completion when the locking unit 55 is locked in the unlocked state or unlocked in the locked setting state. Naturally, the speaker 56 according to the present invention is an additional component and is not a necessary component. In addition, an indicator (not shown) for outputting a light corresponding to the output of the sound by the speaker 56 may be further included.

According to an embodiment of the present invention, the RFID tag 10 may be included in the mobile terminal 30. Hereinafter, the RFID tag is included in the mobile terminal 30 as an example.

 2B is a diagram illustrating a configuration of a mobile terminal having an RFID tag according to an exemplary embodiment of the present invention.

According to FIG. 2B, the mobile terminal 30 includes an RFID tag 31, a button unit 33, an infrared signal generator 35, and an infrared port 37.

As described above, the RFID tag 31 may be generated from a mobile communication company corresponding to the mobile terminal 30.

The button unit 33 is a means for the user to input a password and / or a control command, and an infrared signal corresponding to the user's manipulation of the button unit 33 is generated.

The infrared signal generator 35 performs a function of generating an infrared signal corresponding to the manipulation of the button unit 33. Infrared signals of different frequencies are preset for each button, so that the door lock device 50 can recognize the password by the infrared signal according to each button pressing operation.

The infrared port 37 emits the infrared signal generated from the infrared signal generator 35 to the outside. That is, the infrared signal is transmitted to the infrared receiver 52 of the door lock device 50 to perform a password authentication procedure.

3 is a flowchart illustrating a procedure for setting a lock release of a door lock device according to a preferred embodiment of the present invention.

Each step shown in FIG. 3 may be a step performed independently in each component of the door lock device 50, but will be collectively described as being performed in the door lock device 50 for convenience of description.

According to FIG. 3, in step S310, the door lock device 50 generates a specific frequency signal of a predetermined band, recognizes the RFID tag 31 located within the effective distance of the specific frequency signal, and stores the RFID tag 31 in the RFID tag 31. Read the unique identification number.

In step S320, the door lock device 50 determines whether the primary authentication is successfully performed by comparing the read unique identification number with the first authentication number stored in the storage unit 53. If the primary authentication is not successfully performed, the process proceeds to step S325 and a warning sound is output. However, the first authentication is an authentication procedure using only a unique identification number stored in the RFID tag 31, and a warning sound may not be output when a person without an intention of access is close, so in this case, until the infrared signal is received by step S330. It may wait in S320.

In operation S330, when the first authentication is successfully performed (that is, the unique identification number is authenticated), the door lock device 50 receives the infrared signal generated from the mobile terminal 10, and receives the received infrared signal in a predetermined method. It is converted and recognized as a password.

In operation S340, the door lock apparatus 50 determines whether the second authentication is successfully performed by comparing the recognized password with the second authentication number stored in the storage 53. If the secondary authentication is not successful (for example, an unauthenticated password), the flow advances to step S325 to output a warning sound. Of course, the warning sound output step can be omitted.

If the secondary authentication is successfully completed, the door lock device 50 releases the lock state of the lock unit 55 in step S350.

Here, the order of the first authentication process (steps S310 to S320) and the second authentication process (steps S330 to S340) may be performed in the reverse order. That is, after receiving and authenticating a password from the mobile terminal 10, authentication for the unique identification number stored in the RFID tag 31 may be performed.

Of course, the order of the first authentication process and the second authentication process is not fixed, and the authentication procedure may be performed according to the order received first of the unique identification number and the password.

Therefore, the order of the two authentication procedures may be determined in advance, or the authentication procedure may be performed regardless of the order. In addition, when the order of authentication is determined in the order of the password and the RFID tag 31, the RFID reader 51 is activated to emit a specific frequency only when the password by the infrared signal is authenticated, and accordingly, the second authentication is performed. Procedures may also be performed. This eliminates the need for the RFID reader 51 to emit a particular frequency at any time, thereby saving the energy used to emit a particular frequency.

4A is a flowchart illustrating a procedure of setting a lock of a door lock device according to an exemplary embodiment of the present invention.

The door lock device 50 in which the lock unit 55 is in the unlocked state reads the unique identification number of the RFID tag 31 located within the effective distance in step S410. Subsequently, authentication for the unique identification number is performed in step S420. When the unique identification number is authenticated in step S430, the door is locked, and a lock setting sound corresponding to the completion of the lock is output.

Figure 4b is a flow chart illustrating a procedure for setting the lock of the door lock device according to another embodiment of the present invention.

The door lock device 50 in which the lock unit 55 is in the unlocked state receives the infrared signal from the mobile terminal 30 in step S450. The infrared signal is generated as a specific button or any button of the mobile terminal 30 is pressed. In step S460, the door lock device 50 recognizes that the generated infrared signal is a lock signal and locks the door in step S470. Set and output the lock setting sound corresponding to the completion of the lock.

Of course, even if the door lock device 50 does not receive the unique identification number of the RFID tag 31 or the infrared signal from the mobile terminal 10 to set the lock, it may be automatically switched to the locked state after a predetermined time elapses. Is as described above.

5 is a view showing the door lock device 50 viewed from the outside of the door according to an embodiment of the present invention.

A handle 510 on the outside of the door and two holes 530 and 550 are formed at one side. One hole 530 has a portion that generates a specific frequency to emit a specific frequency to the outside of the portion of the RFID reader 51 mounted inside or inside the door. A part of the infrared sensor is located in the other hall 550 to detect an infrared signal received from the external mobile terminal 30 among the infrared receivers 52. Alternatively, a part of the RFID reader 51 and the infrared sensor may be located together in one hole.

As described above, according to the present invention, a door opening and closing control system using a mobile terminal having more stable security and a control method thereof are recorded by performing two authentication procedures using an RFID tag and a password generated by the mobile terminal. There is an effect that can provide a recording medium.

In addition, a mobile terminal having a key function of opening and closing a door and a door tag control system using a mobile terminal capable of opening and closing the door more conveniently even when the RFID tag is lost and a recording medium recording the control method thereof can be provided. It also works.

In addition, since there is no separate device for opening and closing the door outside the door, it is also possible to provide a door opening and closing control system using a mobile terminal that can reduce the risk of door failure and a recording medium recording the control method thereof. have.
