Description

[0001] The present invention relates to a digital door lock apparatus using a smart phone,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a digital door lock apparatus, and more particularly, to a digital door lock apparatus using a smart phone.

Used in residential facilities and security purposes, locks are installed on the doors to restrict access by outsiders. A digital door lock device, which is a door lock device that is opened and closed by a pre-registered password, is widely used instead of a manual lock device using an existing key.

Recently, digital door lock devices with new functions are being developed by popularization of smart phones. A door lock apparatus using a smart phone is configured to operate a door open / close apparatus of a door lock apparatus using near field communication or commercial wireless communication. To do this, it is necessary to carry the smartphone all the time, so that it can be accessed.

An example of such a digital door lock device is a door lock control method and system (" Prior Art 1 ") of Japanese Laid-Open Patent Application No. 10-2011-0014893. In the prior art 1, input information is input in accordance with a key button operation, authentication is performed using previously stored authentication information, and authentication result information is generated. Then, it is configured to transmit the result information to the registered portable terminal as a communication message. Accordingly, the user can open / close the door lock device in accordance with the control command included in the message. However, although the prior art 1 can control the door lock using the portable terminal, the application range is limited because the portable terminal is registered only. Also, although the prior art 1 uses a portable terminal, the door lock device is not directly opened or closed by directly using a portable terminal such as a smart phone.

Of course, another Korean Patent Registration No. 10-131594 (Prior Art 2) discloses a configuration in which a door is opened or closed by a password input from a key button of a smartphone. However, in the prior art 2, only the configuration for opening and closing the door through the key button of the smartphone is disclosed.

That is, in the above-described related arts, the door is basically configured to open and close the door through key button operation. This means that the door opening and closing method is extremely limited. Therefore, if other options can be selected in addition to the operation of the key buttons, user's convenience can be improved. For example, it is possible to utilize pattern information to be input on a screen by a touch method. Of course, there is a digital door lock device capable of inputting pattern information in a touch manner. However, since it is expensive compared with a general door lock device, its use is limited. Instead, as another method of applying the touch method, it is possible to use a touch method of a smart phone which has become popular recently. In other words, the use of a high-priced touch-type digital door lock device can be eliminated, and its function can be implemented using a smart phone.

In addition, most of the doors are equipped with cameras. However, these cameras are now used only as a way to identify who the visitor is. That is, it is enough to check the visitor and open the door by manipulating the door-off button indoors. Therefore, if there is no one in the room, the camera can not open the door even if the visitor is photographed.

Korean Patent Publication No. 10-2011-0014893 (February 14, 2011, door lock control method and system) Korean Patent No. 10-1315940 (October 1, 2013, door lock system using smart phone)

It is an object of the present invention to provide a digital door lock device using a smart phone that can open and close a door using not only a password input using a key button of a digital door lock device but also pattern information derived by operating the key button as a password .

In addition, the present invention provides convenience of door opening / closing operations by displaying one of a key button input screen and a pattern input screen on a screen of a smartphone according to a set door opening / closing method when a smartphone is positioned in front of the door lock device.

In addition, the present invention allows the door to be opened or closed through face information stored in the door lock device.

According to an aspect of the present invention, there is provided a door lock device comprising: at least one sensor mounted on an outer case of a door lock device and sensing a smart phone approaching a front of a door; A first controller for outputting a screen display signal to display at least one of a preset key button input screen and a pattern input screen on the screen of the smartphone when the smartphone is detected; A camera for photographing a face of a visitor according to a control operation of the first control unit when a call button is operated; If the password or pattern information input on the key button input screen and the pattern input screen is normal or if the face information of the visitor photographed by the camera is stored in the storage unit and if the matching ratio is equal to or greater than the preset ratio, And a second controller for controlling the second door lock device.

If the matching ratio is less than the previously set ratio, or if the face information is not stored in the storage unit, the second control unit connects the camera and the manager's smartphone through a predetermined communication network.

And a pattern forming unit for detecting the touch-operated path of the key button of the smartphone to generate the pattern information.

When there are two operating members for opening the door, the first controller combines the key button input screen and the pattern input screen to display the screen sequentially on the smartphone.

According to another aspect of the present invention, when approaching a front side of a door equipped with a door lock device, an input screen of at least one of a key button input screen and a pattern input screen is opened If the input screen is displayed more than once, the next input screen is displayed only when the password or the pattern information inputted to the input screen displayed on the screen is normally authenticated.

The digital door lock device using the smartphone according to the present invention has the following effects.

The present invention allows a key button input screen or a pattern input screen to be displayed on a screen of a smartphone accessing a door, and the door is opened when the password or pattern information input through the input screen is normally authenticated. Accordingly, the user can open the door more easily without taking any additional action. Moreover, since the user uses his or her own smartphone, the risk of leakage of the password or pattern information is minimized, and the complement can be improved.

In addition, the present invention can determine whether the door is opened from a remote place by using the face information of a visitor in the absence of a smart phone, thereby enabling the convenience of the door opening method to be pursued.

2 is a flowchart showing a process of opening a door using password and pattern information according to an embodiment of the present invention.
3 is a flowchart illustrating a process of opening a door using face information of a visitor according to another embodiment of the present invention.

The present invention opens a door using a password or pattern information using a key button provided on a smart phone and allows a visitor to open the door through his or her own stored face information and an additional authentication procedure, Thereby opening and closing the door provided with the apparatus more safely and conveniently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a digital door lock device using a smartphone according to the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram of a digital door lock device according to an embodiment of the present invention. In this case, a digital door lock device (hereinafter referred to as a 'door lock device') 100 is installed in a door (not shown). The door lock apparatus 100 includes a set of an outer case 110 and an inner case 130, which are disposed on the outdoor side and on the indoor side, respectively, with the door therebetween, and are coupled to each other. The door between the outer case 110 and the inner case 130 is not shown, but an operation member for locking the door by inserting / releasing the door latch is formed. At this time, the door latch portion and the operation member may be two. This is to allow the door to be opened by entering the password twice.

A button input unit 112 having a key button 113 for inputting a password is provided in the outer case 110 in a protective cover (not shown). Of course, the protective cover may not be configured and the button input unit 112 may be exposed to the outside. The external case 110 is provided with a call button 115 for requesting a visitor to open the door, a camera 116 for photographing a visitor, a microphone 117 for receiving a voice data signal, a speaker 118 for outputting a voice data signal, And so on. At least one sensor 119 for detecting the approach of the smartphone 1 is mounted on the outer case 110. The sensor 119 is for displaying a key button input screen or a pattern input screen on the screen of the smartphone 1 when the smart phone 1 approaches the front of the door.

The inner case 130 includes a selection unit 131 for selecting a key input screen or a pattern input screen to be displayed on the screen of the smartphone 1 sensed by the sensor 119. The selection unit 131 is operated by the user. Accordingly, the smartphone 1 located outside the door displays either a key button input screen or a pattern input screen as a password input screen required for the authentication procedure. Alternatively, the key button input screen and the pattern input screen may be displayed in order.

In addition, the inner case 130 is configured with a storage unit 132 for storing password information according to the combination of the key buttons 113 and pattern information according to the pattern input. The password can be set by inputting a predetermined number using the key button 113. [ The pattern input also uses the key button 113. That is, the present invention is not a door lock apparatus having a relatively expensive touch screen, but a door lock apparatus having a key button 113 as a physical structure, because a pattern can not be input in a general manner of touching a screen. Thus, a pattern is formed by operating the keys provided in the button input unit 112, that is, nine (1 to 9) or twelve (0 to 9, *, #) key buttons. For example, when 1, 2, 3, 5, 7, 8, and 9 are operated successively, the pattern of the alphabet Z can be input. Here, the password and the pattern information may be plural. That is, when there are two door latch portions and two actuating members, they must be released. At this time, the password may be composed of only the password, the pattern information alone, or the combination of the password and the pattern information.

On the other hand, the face information of the face of the visitor can be stored in the storage unit 132. The stored face information is used to authenticate whether or not the visitor is a passable visitor by comparing the face information of the visitor photographed by the camera 116. [ At this time, the face information is not unconditionally stored in the storage unit 132, but only the facial information that is accepted as outgoing is stored. When the user confirms the facial information captured by the camera 116 mounted on the outer case 110 and then selectively stores the facial information, or when a visitor who wants to access the facial information transmits his or her face photograph to the user in a file form, Can be stored. That is, the face information of the person who is determined that the user can not enter or leave is not stored. In this case, the user directly identifies the visitor and selectively opens the door.

The inner case 130 includes a start button 133 and an end button 134 for indicating the start and end of pattern input for storing the pattern information in the storage unit 132 and a key button 113 The pattern forming unit 135 may be configured to form a pattern with reference to the path. The pattern forming unit 135 forms a pattern by detecting the operation sequence of the key button 113. [

A first control unit 136 and a second control unit 137 for controlling the operation of the door lock apparatus 100 are formed in the inner case 130. When the smartphone 1 is detected by the sensor 119, the first control unit 136 outputs a screen display signal to display a key button input screen or a pattern input screen, and also photographs the face of the visitor at the time of a visitor call And controls the operation of the camera 116. The second control unit 137 controls face information matching and door opening / closing as a whole. That is, the second control unit 137 checks whether the face information shot by the camera 116 is stored in the storage unit 132, and maintains the door in the open or closed state according to the result. If the matching degree between the photographed face information and the stored face information is less than a preset threshold value, the user and the visitor may control the authentication procedure through the video call. Of course, when the face information of the visitor is not stored, the face information is stored in the storage unit 132 through the video call, and the door is opened, but the face information is not stored unconditionally. Although the first embodiment of the present invention is described as being divided into the first controller 136 and the second controller 137, the first controller 136 and the second controller 137 may be configured as one controller, It is of course possible to configure it to perform control operations.

And a communication unit 138 for transmitting / receiving various control signals for communication with the smartphone 2 is formed in the inner case 130. That is, it means that a video call can be made. When the smartphone 2 user is outside, the smartphone 2 is connected to the door lock apparatus 100. The user uses his / her own smartphone 2 and a visitor outside the door transmits his / her face information and voice through the camera 116, the microphone 117 and the speaker 118, The user is in video communication with the user while receiving the voice.

Next, the operation of the digital door lock device will be described. First, a process of opening the door using the password and the pattern information will be described with reference to FIG.

The user stores at least one of a password and pattern information for opening the door in the storage unit 132 (S100). The password is input by manipulating the numeric keys and special keys (*, #, etc.) arranged in the button input unit 112 and stores it in the storage unit 132. When the pattern information is used, the user presses the start button 133 and operates the numbers and special keys arranged in the button input unit 112. When the operation is completed, the end button 134 is operated. Then, the pattern forming unit 135 forms a pattern according to the path of the operated number or the special key, and stores the pattern in the storage unit 132. At this time, a plurality of password and pattern information may be stored in the storage unit 132, or a combination of password and pattern information may be stored as one password. In the case of a plurality of passwords or pattern information, the door can be opened by giving a password to each user and each person judged to be possible to access, or if a person normally authenticates all of the plurality of passwords, If the information is entered normally, it means that the door can be opened. If a password is assigned to each individual, the password or pattern information is corresponded to each telephone number as shown in Table 1 below. In Table 1, the pattern information A is a result of sequentially pressing '2-4-7', '2-6-9', and '4-5-6'.

Managers / Visitors Phone number password Remarks User A 010-1234-5678 34671! password User B 010-2345-6789 124552 password ·

· ·
·
· ·
·
· ·
·
· User C 010-3456-7890 A Pattern information

While storing the password and pattern information in the storage unit 132, the user operates the selection unit 131 to select a key button input screen or a pattern input screen to be displayed on the screen of the smartphone 1 (s101). Or the key button input screen and the pattern input screen may be displayed in order.

In this initial setting state, the sensor 119 senses the outside of the door (s102). And no smartphone will be detected unless there is a person to access the result of the sensing. At this time, no control operation related to the door opening is performed. On the other hand, when the smartphone 1 is detected (s104), the sensor 119 transmits the detection result to the first control unit 136. [ At this time, it is possible to detect the smartphone 1 because the smartphone is in a standby state. If the smartphone 1 is powered off, it can not be detected.

The first control unit 136 transmits a screen display signal to the smartphone 1 so as to display one of the key button input screen and the pattern input screen selected by the selection unit 131 at step s106. Then, the smartphone 1 displays one of the key button input screen and the pattern input screen in the standby state according to the screen display signal. Accordingly, the password input or the pattern information can be input by using the key button input screen or the pattern input screen displayed on the screen of the smartphone 1 (s108). The inputted password or pattern information is transmitted to the second control unit 137. The second control unit 137 compares the received information with the information stored in the storage unit 132 (S110), and controls the door to be opened when it is normally authenticated (S112).

As long as the smart phone 1 is located at the front of the door, a key button input screen or a pattern input screen is displayed so that a password or a pattern can be input to the screen of the smart phone 1 for opening the door , So that the door can be opened without taking any other action.

On the other hand, the smartphone 1 may display the key button input screen and the pattern input screen in order according to the password setting method. If the pattern information screen or the key button screen is displayed, the second authentication process is performed. In this case, the door is opened only when all the authentication procedures are normally completed. However, this can be applied to the door having two operation members. That is, when the first authentication is completed, one operation member is released, and when the second authentication is completed, the other operation member is released.

3 is a flowchart illustrating a process of opening a door using face information of a visitor according to another embodiment of the present invention. 3 may correspond to a case where the visitor does not have the smartphone 1 or the sensor 119 can not detect the smartphone 1 while the battery of the smartphone 1 is fully discharged . Further, the user carries his / her own smartphone 2, but assumes that he / she is not in the room but is outside.

To explain this, the visitor presses the call button 115 located outside the door (s120). Then, the first control unit 136 turns on the camera 116 to photograph the face of the visitor (s122). The first control unit 136 may output a guidance message such as 'photographing is taking place' through the speaker 118 for the face photographing. If the face of the visitor is photographed through this process, the second control unit 137 checks whether the photographed face information is stored in the storage unit 132 (s124).

As a result, if it is stored in the storage unit 132 (s126), it can be regarded as a visitor who can enter and leave, so that the second control unit 137 opens the door. At this time, the second control unit 137 compares the photographed face information with the face information previously stored in the storage unit 132, and judges that the comparison result is reliable only when the comparison result is about 90% or more (s128). If it is 90% or more, the door is opened (s130). If it is less than 90%, it is determined that the same person is unreliable and the door is not opened (s132). If the face matching ratio is less than 90% according to the comparison result, the second controller 137 communicates with the smartphone 2 for the user and controls the video call with the visitor (s134). Accordingly, the user can confirm the face of the visitor (s136) and selectively control the door to be in the open or closed state (s138). On the other hand, if the matching ratio is less than 90%, the first control unit 136 performs the face photographing once or twice and the second control unit 137 compares the face information with the stored face information again, There may be an effort to improve. Nevertheless, if the comparison result is still less than 90%, a video call is made. When the visitor is confirmed, the user uses the smartphone 2 to open the door. At this time, the smartphone 2 will transmit the door open signal to the second controller 137 through the communication network.

On the other hand, if the face information is not stored in the storage unit 132 or is less than 90% as described above, the door opening or door blocking is performed through the video call as described above, Information is stored in the storage unit 132. [ Of course, in the case of a visitor judged not to have to open the door through a video call, the captured face information need not be stored. However, if the visitor's face information is stored, You do not need to do this.

When the door is opened by a smartphone, it is determined whether or not the visitor's face information is stored. When the door is opened, the door is automatically opened. If not, the visitor's face information is stored To identify the visitor and to open the door.

As described above, the present embodiment provides a technical point that the digital door lock device can be controlled using a smart phone.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
