Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

First, a door lock control system according to the present invention will be described with reference to FIG.

1, the door lock control system of the present invention includes a door lock apparatus 100 for randomly generating an array of keypads related to a password input, a control unit 100 for periodically checking the communication connection state with the door lock apparatus 100, A server 200 for monitoring the occurrence of a specific situation related to the door lock apparatus 100 on the basis of the door lock apparatus 100 and a user terminal 300 for performing at least one remote control function for remotely controlling the door lock apparatus 100 .

Each of the devices of the door lock control system operates in cooperation with each other through a network to provide smarter functions based on the Internet of Things (IoT) technology.

Here, the network may be a wired network such as a local area network (LAN), a wide area network (WAN) or a value added network (VAN), a mobile radio communication network, The present invention can be implemented in all kinds of wireless networks such as Bluetooth, Wireless Broadband Internet (Wibro), and High Speed Downlink Packet Access (HSDPA), and there is no particular restriction as long as it can be applied to the IoT technology.

Accordingly, the door lock control system of the present invention can provide a door lock service (hereinafter referred to as smart door lock service) according to differentiated functions while improving the security of the existing door lock by controlling the door lock device 100 based on the IoT technology Hereinafter, the features of each device for providing such a smart door lock service will be described in more detail.

First, the configuration of the door lock apparatus 100 will be described in more detail.

The door lock apparatus 100 performs basic operations such as door opening and closing and malfunction notifications generally provided in a door lock and provides a smart door lock service in cooperation with the server 200 and the user terminal 300 through a network Lt; / RTI > At this time, various means such as voice recognition, fingerprint recognition and the like may be used in addition to the password for opening and closing the door.

2, the door lock apparatus 100 includes a keypad management unit 110, a function control unit 120, a camera unit 130, a storage unit 140, a display unit 150, and a local communication unit 160, As shown in FIG.

The keypad management unit 110 randomly generates an array of keypads related to the input of a password to improve security.

More specifically, the keypad management unit 110 randomly generates an array of keypads when the user performs a control (e.g., key press / touch) related to the display of the keypad to input the password.

That is, when the user inputs a password, the keypad management unit 110 arranges the positions of the numbers displayed on the keypad at new positions every time so that a person can not memorize the position of the keypad.

Accordingly, when the user inputs a password, even if the position of the keypad corresponding to the password is exposed to the outside, the unauthorized access can be blocked by the keypad arranged at random.

The function control unit 120 controls the basic operations such as door open / close and malfunction notification, which are generally provided in the door lock, to be performed.

More specifically, when the user inputs a password to open a door, the function control unit 120 determines whether or not to open or close the door based on a result of comparing the entered password with a predetermined password.

That is, when the input password matches the predetermined password, the function control unit 120 determines that the input is a normal access, and controls the door to be opened.

On the other hand, if the entered password does not match the pre-set password, the function control unit 120 determines that an abnormal access is attempted and controls the door not to be opened.

Thereafter, when an abnormal access is attempted more than a predetermined number of times, the function control unit 120 shoots a forward image through the camera to generate a negative trial image, and confirms an access log. Then, the function control unit 120 transmits the unauthorized access determination information including the unauthorized attempt image and the access log to the server 200.

Accordingly, the server 200 functions as a firewall server (FireBase Cloud Messaging Server), generates a push message, which is informal access notification information, based on the unauthorized access determination information, and transmits the generated push message to the user terminal 300 . In the embodiment of the present invention, the server 200 includes a function of a push server. However, the present invention is not limited to this, and the server 200 and the push server may be divided into separate devices.

Then, the user terminal 300 receives the push message and can check the illegal access decision information received from the door lock apparatus 100. [ Here, the push message is basically transmitted to a specific user, but may also be transmitted to a plurality of users using the door lock apparatus 100.

In the case where unauthorized entry / exit is detected according to the above description, since the door lock apparatus 100 simply generates an alarm to notify the unauthorized entry / exit, if the user is not present in the house, the alarm can not be checked, However, in the present invention, it is possible to provide unauthorized access determination information, that is, an unauthorized attempt image and an access log, in a push message format in real time, so that it is possible to quickly and easily cope with unauthorized access.

Meanwhile, when the security time is set so that access from the user terminal 300 through the door lock apparatus 100 can be blocked, the function control unit 120 monitors whether access is attempted during the security time.

Here, the security time is a time set by the user so that all access through the door lock device 100 can be blocked, and the operation of the keypad during this time is regarded as unauthorized access.

That is, when the keypad of the door lock apparatus 100 operates for access during the security time, the function controller 120 regards the keypad as illegal access and generates unauthorized access determination information for informing abnormal access as described above To the server (200).

Then, the server 200 generates a push message based on the unauthorized access determination information and transmits the push message to the user terminal 300. Accordingly, the user terminal 300 receives the push message and can check the unauthorized access determination information received from the door lock apparatus 100.

The storage unit 140 stores all pieces of information transmitted and received (e.g., a predetermined password, an access log, an unauthorized attempted image, etc.) to provide a smart door lock service.

The display unit 150 may be an area for displaying and outputting information to a user when driving the door lock apparatus 100 and may be a display device such as a liquid crystal display (LCD).

The short-range communication unit 160 determines whether to open or close the door by confirming the specific tag information input through short-distance wireless communication.

More specifically, when the specific tag information is confirmed from the user terminal 300 via the short-range wireless communication, the short-range communication unit 160 determines whether or not the corresponding inquiry is opened or closed based on the result of comparison between the specific tag information and the pre- do.

That is, the short-range communication unit 160 detects a user identifier (UID) from the user terminal 300 when it is confirmed that the user terminal 300 is connected through short-distance wireless communication. Then, the short-range communication unit 160 receives the tag identifier (UID) previously stored in the server 200. [

Then, the short-range communication unit 160 compares the previously stored tag identifier (UID) with the detected tag identifier (UID).

That is, if the pre-stored tag identifier (UID) matches the detected tag identifier (UID), the short-range communication unit 160 determines that it is a normal access and leaves the access log to the server 200 and opens the door. On the other hand, if the pre-stored tag identifier (UID) does not match the detected tag identifier (UID), the short-range communication unit 160 determines that an abnormal access is attempted and controls the door not to be opened.

Next, the configuration of the server 200 will be described in more detail.

The server 200 performs overall management / control related to providing the smart door lock service and maintaining the connection of the network.

In particular, the server 200 monitors the occurrence of a specific situation related to the door lock apparatus 100 based on a result of periodically checking the communication connection state with the door lock apparatus 100.

The server 200 may include a monitoring unit 210, a service management unit 220, and a storage unit 230, as shown in FIG.

The monitoring unit 210 periodically checks the communication connection state with the door lock apparatus 100. [

More specifically, the monitoring unit 210 receives a specific bit including identification information from the door lock apparatus 100 at the time of initial communication with the door lock apparatus 100, and based on the result of checking whether the identification information is stored, Specifies a timer to periodically check the connection status.

Here, the specific bit is transmitted / received by a function called "HeartBeat" performed by the server program, and it is possible to check whether the communication connection between the server 200 and the door lock apparatus 100, such as heartbeat, Signal. In this specific bit, identification information for each door lock device, that is, an IP address is included so that the server 200 can identify a plurality of door lock devices.

That is, when the specific bit including the identification information is received from the door lock apparatus 100, the monitoring unit 210 detects the identification information from the specific bit. Thereafter, the monitoring unit 210 specifies a timer based on a result of checking whether the identification information exists or not based on the user information table stored in the storage unit 230.

At this time, if the identification information is not stored in the pre-stored user information table, the process of determining that the door lock apparatus 100 newly registers and storing the detected identification information in the user information table will be performed first.

If the identification information is stored in the pre-stored user information table, the monitoring unit 210 transmits a specific bit after the door lock apparatus 100 completes the new registration. Therefore, Timer is specified.

If a timer is specified in accordance with the above-described procedure, the monitoring unit 210 checks whether or not a specific bit is periodically received for a time designated by the timer.

That is, when a specific bit is periodically received for a time designated by the timer, the monitoring unit 210 determines that the communication connection state with the door lock apparatus 100 corresponding to the identification information included in the specific bit is normal. Then, the monitoring unit 210 resets the timer before expiration of the timer to continuously check the communication connection state.

On the other hand, if a specific bit is not received periodically for a time designated by the timer, the monitoring unit 210 determines that the communication connection state with the door lock apparatus 100 corresponding to the identification information included in the specific bit is abnormal .

That is, the monitoring unit 210 determines that the communication connection with the door lock apparatus 100 corresponding to the identification information is terminated by the specific situation, and informs the user terminal 300 of the occurrence of the specific situation.

Here, the specific situation includes at least one of failure / breakage of the door lock apparatus 100 corresponding to the identification information, occurrence of network abnormality between the door lock apparatus 100 and the server 200 corresponding to the identification information, and performance of the door lock basic operation .

Accordingly, the user can remotely monitor whether or not a specific situation related to the door lock apparatus 100 occurs. Therefore, the user can check in real time whether a physical breakdown or breakage of the door lock apparatus 100 located at a remote location or a network abnormality occurs It is possible to provide a door lock service which is more secure than the conventional one.

On the other hand, when a specific situation occurs due to execution of a door lock basic operation (e.g., door opening and closing), it is checked whether or not a specific bit that has been disconnected after the execution of a basic operation (e.g., door open / close) is normally received again. It is preferable to inform the user terminal 300 of the completion of the process.

The service management unit 220 determines whether the service is blocked based on a result of checking whether a specific situation occurs or not from the monitoring unit 210. Hereinafter, it will be described that the specific situation is not a door lock basic operation but a failure / breakage of the door lock apparatus 100 or a network anomaly.

More specifically, when the monitoring unit 210 determines that a specific situation has occurred, the service management unit 220 controls the remote control function so that a part of the remote control function is not performed because the communication connection state is abnormal.

That is, when the communication connection state is abnormal, the service management unit 220 blocks a specific remote control function related to generating a temporary password among at least one remote control function that can be performed by the user terminal 300.

Here, if the temporary password is used once unlike the password preset by the user, the temporary password is deleted so that it can no longer be used. In case of the deletion method, the user may delete the temporary password directly using the user terminal 300, Or a method of automatically deleting data after a predetermined period of time.

In this regard, FIG. 4 shows an example in which a temporary password is generated to invite a friend.

4, when a specific remote control function related to generating a temporary password is requested from the user terminal 300, the server 200 transmits the predetermined password to the door lock apparatus 100 and the server (S10-S12) based on the result of checking whether the communication connection state between the mobile communication terminal 200 and the mobile communication terminal 200 is normally maintained.

That is, the server 200 generates a temporary password only when the communication connection state is normal, and shares it with the door lock apparatus 100. Thereafter, the server 200 transmits the temporary password to the user terminal 300.

Then, the temporary password is displayed on the user terminal 300, and the user transmits the displayed temporary password to the terminal of the invitee through various message transmission methods (e.g., SMS, KakaoTalk, etc.) (S13).

If the temporary password is transmitted to the terminal of the invitee and the invitee inputs the temporary password to the keypad of the door lock apparatus 100, the door lock apparatus 100 transmits the temporary password received from the server 200 and the invitee Based on the result of checking whether or not the temporary password inputted by the door lock apparatus 100 is matched (S14).

As described above, generating and using a temporary password is an important part of security. Therefore, in the present invention, when the communication connection state between the door lock apparatus 100 and the server 200 is abnormal, It will block certain remote control functions.

Referring again to FIG. 3, the storage unit 230 stores all information for providing a smart door lock service.

That is, the storage unit 230 stores all information transmitted and received when interlocked with the door lock apparatus 100 to provide a smart door lock service, and stores all information transmitted and received when the user terminal 300 is interlocked with the door lock apparatus 100 .

Since such information is stored in a PHP (Hypertext Preprocessor) file format, the PHP file can be called from the user terminal 300 to fetch or change data from the storage unit 230.

In the embodiment of the present invention, the user terminal 300 accesses the PHP file through the server 200, directly accesses the storage unit 230 of the server 200, and transmits information using a query But it is needless to say that the information stored in the storage unit 230 may be transmitted in such a manner that the storage unit 230 of the server 200 is managed using a cloud server (e.g., a push server).

Hereinafter, information stored in the storage unit 230 will be described in more detail with reference to Tables 1 to 7.

Table 1 is a user information table. User information such as a user ID, a user password, a door lock password, a user name, a user IP address, and a door lock serial number are stored.

That is, a user who uses the door lock apparatus 100 shares an ID for using the application installed in the user terminal 300 and an ID for using the door lock apparatus 100 in the user information table, And an IP address for periodically confirming the IP address.

Table 2 is a security information table, and information related to the security time setting is stored so that entrance and exit through the door lock apparatus 100 can be blocked.

That is, in the security information table, when the user ID is created with the initial membership, the security time is stored as a default value of 0: 0 (default value for time).

Next, Table 3 is a log table, and stores access time, access success or user ID corresponding to the access log of the door lock apparatus 100, and the like.

Next, Table 4 is the temporary password related table, and the user ID and the temporary password are stored.

In the case of the temporary password stored in the temporary password related table, the temporary password is immediately deleted from the temporary password related table if it is used to access once.

Next, Table 5 is a push-related table, and a user ID and a token used in the application of the user terminal 300 are stored.

That is, the push related table stores a token, which is a kind of application ID generated when the application is initially installed in the user terminal 300. These tokens are deleted or reinstalled depending on whether the application is deleted or not.

Next, Table 6 shows a tag identifier (UID) table, which stores a tag identifier (UID) corresponding to a specific tag (Tag) connected via short-range wireless communication (e.g., NFC).

Next, Table 7 shows the unauthorized access-related table, which includes the unauthorized attempt image generated by shooting forward through the camera, the file name in the storage unit 230, the upload time, and the user ID. At this time, the upload time may be a time corresponding to the time taken from the camera.

Next, the configuration of the user terminal 300 will be described in more detail.

As shown in FIG. 7, the server 200 periodically checks the communication connection state with the door lock apparatus 100 (S100).

More specifically, upon initial communication with the door lock apparatus 100, the server 200 receives a specific bit including identification information from the door lock apparatus 100, and based on the result of checking whether the identification information is stored, Specifies a timer to periodically check the status.

That is, when receiving a specific bit including identification information from the door lock apparatus 100, the server 200 detects the identification information from the specific bit. Thereafter, the server 200 designates a timer based on the result of checking whether the identification information exists based on the pre-stored user information table.

At this time, if the identification information is not stored in the pre-stored user information table, the process of determining that the door lock apparatus 100 newly registers and storing the detected identification information in the user information table will be performed first.

If the identification information is stored in the pre-stored user information table, the server 200 transmits a specific bit after the door lock apparatus 100 completes the new registration. Therefore, the timer 200 for periodically confirming the communication connection state .

If a timer is specified in accordance with the above-described procedure, the server 200 checks whether a specific bit is received periodically for a time designated by the timer (S101).

Thereafter, the server 200 resets the timer before expiration of the timer to continuously check the communication connection state.

On the other hand, if it is determined in step S101 that the specific bit is not periodically received for the time designated by the timer, the server 200 determines that the communication connection state with the door lock apparatus 100 corresponding to the identification information included in the specific bit is abnormal .

That is, the server 200 determines that the communication connection with the door lock apparatus 100 corresponding to the identification information is terminated by the specific situation, and notifies the user terminal 300 of the occurrence of the specific situation (S102-S103 ).

Here, the specific situation includes at least one of failure / breakage of the door lock apparatus 100 corresponding to the identification information, occurrence of network abnormality between the door lock apparatus 100 and the server 200 corresponding to the identification information, and performance of the door lock basic operation .

More specifically, the server 200 determines whether or not to block the service based on a result of checking whether a specific situation occurs. Hereinafter, it will be described that the specific situation is not a door lock basic operation but a failure / breakage of the door lock apparatus 100 or a network anomaly.

That is, when the communication connection state is abnormal, the server 200 blocks a specific remote control function related to generating a temporary password among at least one remote control function that can be performed by the user terminal 300.

Thereafter, the server 200 generates a blocking request message requesting to block the specific remote control function, and transmits the blocking request message to the user terminal 300.

When the shutdown request message is received from the server 200 in accordance with the above-described procedure, when the user executes the application for remote control of the door lock apparatus 100, the user terminal 300 displays a remote control menu Even if the friend invitation 430 is selected from the list 400, the control is inhibited from being performed.

Meanwhile, when the security time setting 450 of the remote control menu list 400 is selected, the user terminal 300 provides a screen for setting a security time so that entrance and exit through the door lock apparatus 100 can be blocked (S105).

When the user sets the security time, the user terminal 300 generates a security time notification message so that all access through the door lock apparatus 100 can be blocked during the set security time, and transmits the security time notification message to the door lock apparatus 100 and / To the server 200 (S106, S107).

Then, the door lock apparatus 100 stores the security time received from the user terminal 300, and monitors whether or not access is attempted during the security time (S108).

As a result of the determination in step S108, if access is attempted during the security time, the door lock apparatus 100 shoots forward through the camera to generate an unauthorized trial image, and confirms the access log. Then, the door lock apparatus 100 transmits the unauthorized access determination information including the unauthorized attempt image and the access log to the server 200 (S109, S110).

When the unauthorized access determination information is received from the door lock apparatus 100 in accordance with the above description, the server 200 generates a push message, which is the unauthorized access notification information, based on the unauthorized access determination information, and transmits the generated push message to the user terminal 300 (S111, S112).

Accordingly, the user terminal 300 receives the push message and confirms the unauthorized access decision information received from the door lock apparatus 100, so that the user terminal 300 can respond promptly (S113).

At this time, it is desirable to provide a function of allowing the notification-related processing to be performed easily if the user decides the coping method by confirming and reporting the unauthorized access.

On the other hand, if it is determined in step S108 that no access is attempted during the security time, the door lock apparatus 100 performs a process after step S114 of performing basic operations such as opening / closing of a door, .

That is, when the user inputs a password to open a door, the door lock apparatus 100 determines whether or not the door is opened or closed based on a result of comparing the entered password with a predetermined password.

At this time, if the entered password matches the pre-set password, the door lock apparatus 100 determines that the door is normally accessed and controls the door to be opened.

On the other hand, if the input password and the predetermined password do not match, the door lock apparatus 100 determines that an abnormal access is attempted and controls the door not to be opened.

Thereafter, when the abnormal access is attempted more than the predetermined number of times, the door lock apparatus 100 shoots forward through the camera to generate an unauthorized trial image, and confirms the access log. Next, the door lock apparatus 100 will perform the process after the above-described step S109 for transmitting the unauthorized access determination information including the unauthorized attempt image and the access log to the server 200. [
