Although the terms used in the present invention have been selected as general terms that are widely used at present, there are some terms selected arbitrarily by the applicant in a specific case. In this case, the meaning described or used in the detailed description part of the invention The meaning must be grasped.

Hereinafter, the technical structure of the present invention will be described in detail with reference to preferred embodiments shown in the accompanying drawings.

However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Like reference numerals designate like elements throughout the specification.

Referring to FIG. 2, a door lock opening device 100 according to an embodiment of the present invention includes a portable terminal 110 and a door lock 120.

The portable terminal 110 is a terminal equipped with a display 111 capable of emitting visible light, and may be a portable terminal such as a smart phone.

However, it is possible to substitute any portable terminal capable of emitting VLC data with visible light by a VLC communication program, which will be described below, such as a tablet PC in addition to a smart phone.

In addition, the portable terminal 110 emits coded visible light for the set password, and a VLC communication program is stored therein.

In addition, the VLC communication program may be stored in a storage medium such as an SD card readable by the portable terminal 110 and read by the portable terminal 110.

However, the VLC communication program may be stored in the internal memory of the portable terminal 110 when the portable terminal 110 is manufactured.

In addition, the portable terminal 110 may download and store the VLC communication program from a server system having a storage capable of storing the VLC communication program and a communication means that can be connected to the portable terminal 110 through a communication network have.

The server system may be a server system capable of transmitting the VLC communication program according to a download request of the portable terminal 110, for example, 'Android Market', 'T Store', or 'App Store'.

3, the functions of the VLC communication program will be described in detail. The VLC communication program 112 includes a password input unit 112a, a VLC data encoding unit 112b, Means 112b and VLC data transmitting means 112c to cause VLC data to be output as visible light through the display 111 of the smartphone 110. [

Also, the password input unit 112a receives a password from a user, displays a ten-key on the display 111, and receives a password from a user.

However, the ten-key may be replaced by a character input key, such as a Qwerty key-pad.

After the password is initially set, the password input means 112a may display only the hot key such as 'Open' without displaying the ten-key, and when the hot key is input, it is recognized that the password is input can do.

In addition, the VLC data encoding unit 112b encodes the secret number to generate VLC data.

In addition, the VLC data is data for carrying information by carrying information on visible light and transmitting information by turning on light as digital information '1' and off as digital information '0'.

In addition, the VLC data encoding unit 112b may insert an identification code into the header of the VLC data to distinguish between the light for VLC data transmission and the external light noise, And inserts a CRC (Cyclic Redundancy Check) into the Tail.

The error detection code may use an error detection code such as a parity bit or a Hamming code in addition to the cyclic code.

The VLC data encoding unit 112b scrambles or encrypts the VLC data so that the VLC data can not be recognized by other devices other than the door lock 120, .

The VLC data transmitting means 112c turns on / off the display 111 of the smartphone 110 to output the VCL data as visible light.

In addition, the VLC data transmitting unit 112c can reduce the power consumption of the smartphone 110 by turning on / off only a certain area of the display 111. [

The door lock 120 is attached to the door and opens and closes the door. The door lock 120 receives the visible light from the smartphone 110 and decrypts the received visible light. When the decrypted data is stored in the door, Open.

In addition, the door lock 120 may include a VLC data setting mode for initially receiving and storing VLC data from the smartphone 110, and an open / close mode for opening the opening / closing device when VLC data is input after setting VLC data And the door lock 120 may be provided with a mode change button (not shown) for switching the modes.

The door lock 120 includes a visible light receiving unit 121, a VLC data decoding unit 122, a VLC data storage unit 123, and a door lock opening / closing unit 124.

In addition, the visible light receiving unit 121 receives VLC data by receiving visible light from the smartphone 110.

For example, the visible light receiving unit 121 may receive the VLC data, including a photodiode (not shown) for receiving visible light, and an A / D converter for converting the signal of the photodiode into a digital signal.

Also, the VLC data decoding unit 122 decodes the VLC data and recognizes the password.

The VLC data storage unit 123 stores the VLC data decoded by the VLC data decoding unit 122 when the door lock 120 is in the setting mode.

When the door lock 120 is in the opening and closing mode, the door lock opening / closing unit 124 determines whether the VLC data decoded by the VLC data decoding unit 122 is stored in the VLC data storage unit 123, The opening / closing device of the door lock 120 is opened.

That is, according to the door lock opening device 100 according to the embodiment of the present invention, the door lock 120 can be opened / closed using only the smart phone 110 without using a separate remote controller, will be.

Also, a plurality of different VLC data may be stored in the VLC data storage unit 123, and a plurality of users may set a password using their own smartphone to open and close the door lock.

In this case, the door lock 120 may be useful when opening and closing a door lock (aka 'lobby phone') installed on a common house entrance with a smartphone.

The door lock 120 may include a key input unit 125 for receiving a door lock password and a door lock password storage unit 126 for storing and matching specific VLC data of the door lock password and the VLC data storage unit 123 with each other . ≪ / RTI >

Also, the door lock password may be the same as or different from the password set in the smartphone 110.

That is, even though the VLC data are the same, the smartphone password and the door lock password may be different from each other, so that the security can be enhanced and the password can be conveniently set according to the user's need.

The door lock opening / closing unit 124 opens the opening / closing device of the door lock 120 when the door lock password inputted to the key input unit 120 in the open / close mode is stored in the door lock password storage unit 126.

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 taken by way of limitation in the present invention. Various changes and modifications will be possible.
