Hereinafter, advantages, features, and preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a system for diagnosing the status of a digital door lock and a smart plug according to the present invention. 1, the digital door lock 100 and the smart plug 200 are communicably connected to each other so that the digital door lock and the smart plug are connected to the user terminal (300) or a remote control server (400).

The digital door lock (100) is a device that is installed on a front door or the like to authenticate a user and then release the lock state. The digital door lock 100 according to the present invention includes a keypad 110, an input device 120, a locking device controller 130, a locking device 132, a locking device sensing device 134, a first controller 140, A first memory 150 and a first bidirectional wireless communication unit 160. [ In FIG. 1, the components of the digital door lock 100 according to the present invention are shown separately. However, the components may be integrated or separated according to an embodiment of the present invention. For example, although the keypad 110 and the input device 120 are illustrated as separate components in FIG. 1, the keypad 110 and the input device 120 may be configured as one component according to an exemplary embodiment of the present invention.

The keypad 110 and the input device 120 are components for inputting information (hereinafter referred to as "input information") for authenticating a user to the digital door lock 100, And a character. The input device 120 is a component for recognizing biometric information such as a fingerprint, an access card, an electronic key, and the like. The input device 120 may include a fingerprint scanner, an iris recognition device, a card reader, and an electronic key reader. The input information input to the keypad 110 or the input device 120 is transmitted to the first controller 140. The first controller 140 performs user authentication by receiving input information and comparing it with authentication information stored in the first memory 150 to be described later. When the user is authenticated (for example, when the input information matches the authentication information (Door opening control signal) for releasing the locking device to the lock device control unit 130. [ On the other hand, the first controller 140 outputs a failure signal when the user authentication fails (for example, when the input information does not match the authentication information).

The locking device control unit 130 controls the locking device 132 according to the result of user authentication by the first controller 140. That is, when the user authentication of the first controller 140 is successful as described above (for example, when the input information matches the authentication information), the lock controller 130 sets the door open control signal The locking device 132 is released from the locked state. On the other hand, if the user authentication of the first controller 140 is unsuccessful as a result of the user authentication (for example, if the input information and the authentication information do not match), a failure signal is output from the first controller, . ≪ / RTI > Thus, the locking device 132 remains locked. If the user authentication fails according to the embodiment, a warning sound or the like may be output through a separate output device (not shown). Meanwhile, the locking device sensing part 134 is connected to the locking device 132 to detect whether the locking device is released. The lock detection sensor 134 transmits status information of the detected lock device 132 to the first controller 140. [

The first controller 140 controls the operation of each component of the digital door lock 100 and performs user authentication through input information input through the keypad 110 or the input device 120 as described above. More specifically, when a numeric or character password is input through the keypad 110, the first controller 140 receives the input information, loads the authentication information stored in the first memory 150, do. In addition, when biometric information such as a fingerprint recognized through the input device 120, an access card, and unique information (pin number, etc.) of the electronic key are input, the first controller 140 similarly receives the input information, The authentication information stored in the memory 150 is loaded and it is determined whether or not the authentication information matches. If it is determined that the input information matches the authentication information, the first controller 140 outputs a door open control signal to release the locking device 132 from the locking device control unit 130. In addition, when the user authentication fails, the first controller 140 outputs a failure signal.

On the other hand, the first controller 140 determines whether the digital door lock is malfunctioning or abnormal operation through the states of the respective components of the digital door lock 100. Specifically, the first controller 140 receives input information of the keypad 110 or the input device 120, the operation of the lock device 132 according to the user authentication, the data transmission / reception state of the first bidirectional wireless communication unit 160 So as to determine whether each component is in failure or abnormal operation. The first controller 140 stores the sensed information in the first memory 150 and controls the first bidirectional wireless communication unit 160 to transmit the sensed information to the smart plug 200 To the user terminal 300 and the control server 400. [

Specifically, when the input information input through the keypad 110 or the input device 120 does not coincide with the authentication information but the same ratio is equal to or greater than a predetermined reference value and the same input information is input repeatedly more than a predetermined number of times, 140 can be recognized as a failure of the keypad 110 or the input device 120. For example, if the specific license plate (e.g., "4") of the keypad 110 is bad and the password is "1234 "," 1 ", "2 & The first controller 140 can recognize that the "4" plate of the keypad 110 is malfunctioning. That is, when the input information matching 3 digits of the 4 digits of the authentication information is input more than a predetermined number of times, the first controller 140 recognizes that the license plate for the value that is not inputted as the input information among the authentication information is broken . For example, when the authentication information is "1434" and the input information is "1", "4", and "3" Quot; 4 "plate can be determined to be operating normally, the first controller 140 may determine that the input is an error of the user and can process the failure.

Similarly, when the information of the biometric information such as the fingerprint inputted through the input device 120, the access card or the electronic key does not match the authentication information but the matching information is more than the reference value and the same information is repeatedly inputted a predetermined number of times or more, 1 controller 140 may determine that the input device 120 has failed.

The first controller 140 stores the failure information in the first memory 150 when the keypad 110 or the input device 120 is determined to have failed and outputs the failure information through the first two- To the smart plug 200, the user terminal 300, and the control server 400. At this time, the failure information may include information (name, identification information, etc.) of the component in which the failure occurred, failure content (for example, "4" license plate unrecognized) and failure occurrence time information. Accordingly, the user terminal 300 and the control server 400 can receive the failure information, recognize the failure state, and perform the A / S application processing. According to an embodiment of the present invention, when the keypad 110 or the input device 120 fails, the user is authenticated (e.g., password input) through the user terminal 300, To the digital door lock (100). The first controller 140 receives the information related to the user authentication success of the user terminal 300 through the first bidirectional wireless communication unit 160 and generates a door opening control signal so that the locking device control unit 130 It is possible to control to release the lock state of the lock lever 132.

The first controller 140 outputs the door open control signal and then outputs the door open control signal to the lock controller 130 or the lock device 132 using the status information of the lock device 132 received from the lock device detector 134. [ It is possible to judge whether or not it is faulty. For example, when the first controller 140 compares the input information input through the keypad 110 or the input device 120 with the authentication information and the two pieces of information match to output the door open control signal, The device control unit 130 releases the lock state of the lock device 132. [ However, if the status information of the locking device detected by the locking device sensing part 134 is still locked, the first controller 140 determines that the locking device control part 130 or the locking device 132 has failed. Accordingly, the first controller 140 generates and stores the failure information in the first memory 150, and transmits the failure information to the smart plug 200, the user terminal 300, and the first memory 150 via the first bidirectional wireless communication unit 160. [ To the control server 400.

Also, the first controller 140 can determine whether the first bidirectional wireless communication unit or the second bidirectional wireless communication unit 260 of the smart plug 200 has failed through the operation state of the first bidirectional wireless communication unit 160 . For example, when an ACK (acknowledge) signal is not received within a predetermined time after the first bidirectional wireless communication unit 160 transmits data to the second bidirectional wireless communication unit 260, the first controller 140 transmits a first bidirectional It can be determined that a failure or abnormality has occurred in the reception module of the wireless communication unit 160 or the second bidirectional wireless communication unit 260 of the smart plug 200. [ The first controller 140 may store failure information in the first memory 150 and may transmit failure information to the user terminal 300 and the control server 400 through the first bidirectional wireless communication unit 160. [

The first memory 150 may store IDs of digital door locks, IDs of smart plugs, authentication information, and failure information. The ID of the digital door lock and the ID of the smart plug can be used to recognize the other party when the digital door lock 100 and the smart plug 200 communicate with each other. The MAC address can be used as the ID of the digital door lock and the smart plug. The authentication information is information for authenticating a user by comparing with the input information input through the keypad 110 or the input device 120 and includes biometric information such as a password, fingerprint and iris image, unique information of the access card and electronic key . The fault information is information generated by the first controller 140 by detecting the failure state of each component and includes information (name, identification information, etc.) of the component in which the failure occurred, failure content (for example, And failure occurrence time information. Meanwhile, the first memory 150 may store failure information of the smart plug 200. The failure information of the smart plug 200 can be received through the second bidirectional wireless communication unit 260 of the smart plug as described later.

The first bidirectional wireless communication unit 160 communicates with the second bidirectional wireless communication unit 260 of the smart plug 200 and communicates with the smartphone 300 and the control server 400. The first bidirectional wireless communication unit 160 may support various wireless communication methods such as WiFi, WiFi Direct, bluetooth, Near Field Communication (NFC), Zigbee, and RFID (Radio Frequency Identification).

The smart plug 200 according to the present invention includes a relay 210, a relay control unit 212, an AC-DC conversion unit 220, a consumption current sensing unit 230, a second controller 240, 250 and a second bidirectional wireless communication unit 260. Although FIG. 1 illustrates components of the smart plug 200 according to an embodiment of the present invention, the components may be integrated or separated according to an embodiment of the present invention.

The smart plug 200 is connected to an external power source through the receptacle C and the current supplied to the inside through the receptacle is transmitted to the relay 210 and the AC-DC converter 220. The relay 210 may be disposed on a path of a circuit through which a current supplied from the outside flows. On the other hand, the relay controller 212 turns on / off the relay 210 according to the control signal of the second controller 240. For example, when the power on / off signal transmitted from the digital door lock 100 or the user terminal 300 is received by the second bidirectional wireless communication unit 260, the second controller 240 may turn on or off according to the received signal. off control signal to the relay control unit 212, and the relay control unit turns on or off the relay 210 according to the control signal of the second controller. Meanwhile, the AC-DC converter 220 converts the alternating current (AC) transmitted through the receptacle C into direct current (DC) and supplies the direct current (DC).

The consumption current sensing unit 230 is connected to a circuit connected to the receptacle C and senses the amount of current flowing in the smart plug internal circuit. The amount of current sensed through the consumption current sensing unit 230 is input to the second controller 240.

The second controller 240 controls the operation of each component of the smart plug 200 and outputs a control signal for turning on / off the relay according to an external control signal as described above. Specifically, when a control signal for turning on the power of the smart plug 200 is received from the digital door lock 100 or the user terminal 300 through the second bidirectional wireless communication unit 260, the second controller 240 And generates and outputs a control signal accordingly. The relay control unit 212 turns on the relay 210 according to the control signal of the second controller 240 and current flows to the smart plug 200 to supply power to the electronic device connected to the smart plug. Meanwhile, when a control signal for turning off the power supply of the smart plug 200 is received from the digital door lock 100 or the user terminal 300 through the second bidirectional wireless communication unit 260, And outputs the generated control signal. The relay controller 212 turns off the relay 210 according to the control signal of the second controller 240. Accordingly, since the current is cut off to the smart plug 200, the power is cut off to the electronic device connected to the smart plug.

Meanwhile, the second controller 240 determines whether the smart plug malfunctions or malfunctions through the states of the respective components of the smart plug 200. Specifically, the second controller 240 determines whether the relay 210, the relay control unit 212, or the consumption current detection unit 230 is malfunctioning or abnormal operation through the amount of current sensed by the consumption current sensing unit 230 . For example, when the second controller 240 receives a control signal for the power on of the smart plug 200 from the digital door lock 100 or the user terminal 200 and outputs a control signal, The second controller 240 may determine that there is an abnormality in the relay 210, the relay control unit 212, or the consumption current sensing unit 230, if there is no change in the amount of current sensed by the first controller 240. That is, Conversely, when the control signal for the power off of the smart plug 200 is received from the digital door lock 100 or the user terminal 200 and the second controller 240 outputs the control signal, the consumption current sensing unit 230 The second controller 240 can determine that the relay 210, the relay control unit 212, or the consumption current sensing unit 230 is abnormal if the detected current amount is the current amount of the power supply state. The second controller 240 generates and stores the failure information in the second memory 250 and transmits the failure information to the user terminal 300 and the control server 400 through the second bidirectional wireless communication unit 260. At this time, the failure information may include information (name, identification information, etc.) of the component in which the failure occurred, failure content (for example, "4" license plate unrecognized) and failure occurrence time information.

Also, the second controller 240 can determine whether the first bidirectional wireless communication unit 160 of the second bidirectional wireless communication unit or the digital door lock 100 has failed through the operation state of the second bidirectional wireless communication unit 260 . For example, when the ACK (acknowledge) signal is not received within a predetermined time after the second bidirectional wireless communication unit 260 transmits data to the first bidirectional wireless communication unit 160, the second controller 240 transmits a second bidirectional It can be determined that a failure or abnormality has occurred in the reception module of the wireless communication unit 260 or the first bidirectional wireless communication unit 160 of the digital door lock 100. [ The second controller 240 may store the failure information in the second memory 250 and may transmit the failure information to the user terminal 300 and the control server 400 through the second bidirectional wireless communication unit 260. [

The second memory 250 may store the ID of the smart plug, the ID of the digital door lock, and the failure information. The ID of the smart plug and the ID of the digital door lock can be used to recognize the other party when the smart plug 200 and the digital door lock 100 communicate with each other, and a MAC address or the like can be used. The failure information is information generated by the second controller 240 by detecting the failure state of each component, and may include information (name, identification information, etc.) of the component in which the failure occurred, failure content, and failure occurrence time information. On the other hand, the second memory 250 may store failure information of the digital door lock 100. The failure information of the digital door lock 100 is received through the first bidirectional wireless communication unit 160 of the digital door lock as described above.

The second bidirectional wireless communication unit 260 may also support various wireless communication methods such as WiFi, WiFi Direct, Bluetooth, Near Field Communication (NFC), Zigbee, and RFID (Radio Frequency Identification).

The user terminal 300 receives malfunction information from the digital door lock 100 and the smart plug 200 as a user terminal. In addition, the user terminal 300 stores the received failure information and displays failure information so that the user can recognize the failure of the digital door lock or smart plug. According to an embodiment, the user terminal 300 may perform processing for failure information according to a user input. For example, when the user terminal 300 receives and displays the failure information, if the A / S application request is inputted from the user, the user terminal sends the A / S application Lt; / RTI > In addition, if the failure type of the digital door lock or smart plug can be temporarily resolved, the user terminal 300 can perform an operation accordingly. For example, when the user authentication is not performed due to the failure of the keypad 110 or the input device 120 of the digital door lock 100, the user terminal 300 outputs an authentication screen for authenticating the user, . At this time, the user authentication by the user terminal 300 can be preset by the user, and various methods such as password input, pattern input, biometric information recognition such as fingerprint / iris, and face recognition can be used.

FIG. 3 is a flowchart illustrating a process of diagnosing a status of a digital door lock according to the present invention. FIG. 3 is a diagram illustrating a process of diagnosing whether a keypad and an input device of a digital door lock, a lock controller, and a lock device are failed. Hereinafter, a process of diagnosing a state of a digital door lock according to the present invention will be described with reference to FIG.

When the user inputs input information through the keypad 110 or the input device 120 to open the digital door lock 100, the first controller 140 performs user authentication by comparing the input information with the authentication information (ST100 , ST110). Specifically, the user inputs a password through the keypad 110, or recognizes biometric information such as a fingerprint / iris, an access card, or an electronic key through the input device 120. Input information received or recognized through the keypad 110 or the input device 120 is transmitted to the first controller 140. [ The first controller 140 loads the authentication information from the first memory 150 and compares the received authentication information with the input information.

If the input information does not coincide with the authentication information in ST110, the first controller 140 performs failure processing (ST120, ST130). The alarm sound and warning message corresponding to the user authentication failure may be output through a separate output device of the digital door lock 100 according to the embodiment.

Meanwhile, the first controller 140 determines whether the ratio of the received input information with the authentication information is equal to or greater than a reference value (ST140). For example, when the reference value is 70% and the authentication information is "1234 ", if the input information is" 123 ", the matching ratio is 75%.

In ST140, if the ratio of input information matched with the authentication information is equal to or greater than the reference value, the first controller 140 determines whether the same input value is repeatedly inputted a predetermined number of times or more (ST150, ST160). For example, in the above example, if the reference count is three, the first controller 140 temporarily stores the authentication information "123" as the input information that matches the reference value or more in the first memory 150 in ST140, Is set to one. After repeating the steps ST100 to ST140, if the input information "123" is input again, the first controller 140 determines whether the input information is the same as the existing input information ("123") stored in the memory. Increment the value of the counter by 1 and set it to 2. The first controller 140 determines whether the value of the counter is equal to the reference number, and repeats the process of ST100 to ST160 if the value is smaller than the reference number.

On the other hand, if the processes of ST100 to ST160 are repeated and the same input information whose matching ratio with the authentication information is equal to or larger than the reference value is inputted more than the reference number, the first controller 140 generates the failure information, (ST170). In the above example, when "123" is input again as the input information as a result of repeating the processes of ST100 to ST160, the first controller 140 increases the value of the counter by one. Therefore, the counter value is 3. When the first controller 140 compares the counter value with the reference number, the first controller generates the failure information because the counter value is equal to the reference number. That is, since "123" is repeatedly inputted three times repeatedly as the input information similar to the authentication information "1234 ", the first controller 140 determines that the keypad 110 corresponding to" 4 " It can be judged that the license plate is broken. The first controller 140 generates and stores the failure information in the first memory 150 and transmits the failure information to the smart plug 200, the user terminal 300, and the second smart card 200 through the first two-way wireless communication unit 160 and the communication device 500, To the control server 400. The user terminal 300 and the control server 400 can recognize the failure state and detailed information of the digital door lock 100 by receiving the failure information and can promptly perform the A / S by registering the A / S application.

According to the embodiment, the user terminal 300 can perform user authentication through the user terminal when the configuration part in which a failure occurs after receiving the failure information is the keypad 110 or the input device 120. [ That is, the user terminal 300 outputs a message asking whether to open the digital door lock 100 through separate user authentication, and when the user selects the digital door lock 100, the user authentication proceeds. For example, the user terminal 300 can authenticate a user by inputting a password, inputting a pattern, biometric information recognition such as fingerprint or iris, or face recognition. When the user authentication is successful, the user terminal 300 transmits the control information for releasing the lock state to the digital door lock (100). The control information transmitted from the user terminal 300 is received by the first bidirectional wireless communication unit 160 and transmitted to the first controller 140, and the first controller outputs a door open control signal. The lock control unit 130 releases the lock state of the lock device 132 in accordance with the door open control signal. Accordingly, the user can temporarily release the locked state of the digital door lock 300 using the user terminal 300 even if the keypad 110 or the input device 120 fails.

On the other hand, when the input information matches the authentication information in ST120, the first controller 140 outputs a door open control signal, and the lock controller 130 releases the locked state of the lock device 132 (ST180 ).

The locking device sensing unit 134 senses the state information of the locking device 132 and transmits it to the first controller 140 (ST190).

The first controller 140 determines whether the state information of the lock device coincides with the control signal of the first controller, and generates failure information if the state information of the lock device does not match (ST200, ST170). For example, when the first controller 140 outputs the door open control signal and the detection result of the lock detector 134 indicates that the lock device 132 is in the locked state, the first controller is the lock controller 130 or It can be determined that the lock device 132 or the like has failed. In contrast, when the first controller 140 outputs the door closing control signal but the lock device 132 is in the open state, the first controller can similarly determine that the lock device controller 130 or the lock device has failed have. The first controller 140 generates and stores the failure information in the first memory 150 and transmits the failure information to the smart plug 200, the user terminal 300, and the second smart card 200 through the first two-way wireless communication unit 160 and the communication device 500, And transmits the failure information to the control server 400.

On the other hand, if the state information of the locking device matches the control signal of the first controller 140 as a result of the determination in ST200, each component of the digital door lock 100 waits while maintaining the operation state (ST210).

FIG. 4 is a flowchart illustrating a process of diagnosing a state of a smart plug according to the present invention. FIG. 4 is a diagram illustrating a process of diagnosing whether a relay, a relay control unit, and a consumption current sensing unit of a smart plug according to the present invention have failed. Hereinafter, the process of diagnosing a state of the smart plug according to the present invention will be described with reference to FIG.

When the control information for turning on or off the power of the smart plug 200 is transmitted from the outside, the second bidirectional wireless communication unit 260 receives the control information (ST 300). The control information may be transmitted from the digital door lock 100, the user terminal 300, or the control server 400 or the like.

The received control information is transmitted to the second controller 240, and the second controller outputs a control signal for controlling the relay according to the control information (ST310). For example, when the control information is control information for turning on the power of the smart plug 200, the second controller 240 generates a control signal for turning on the relay 210, and the relay controller 212 Turn on the relay according to the control signal. Meanwhile, when the control information is control information for turning off the power supply of the smart plug 200, the second controller 240 generates a control signal for turning off the relay 210, The relay is turned off.

The consumption current sensing unit 230 senses the amount of current flowing in the circuit of the smart plug 200 (ST320). The amount of current sensed by the current consumption sensing unit 230 is transmitted to the second controller 240.

The second controller 240 determines whether there is a change in the amount of current sensed by the consumption current sensing unit 230 (ST330). That is, the second controller 240 determines whether there is a change in the amount of current after generating the relay control signal.

If there is no change in ST330, the second controller 240 generates failure information (ST340). For example, if the second controller 240 outputs a control signal to turn on the relay 210 but the amount of current sensed by the consumption current sensing unit 230 is "0 " or below the reference value, . If the second controller 240 outputs a control signal for turning off the relay 210 but the amount of current sensed by the current consumption sensing unit 230 is equal to or greater than the reference value, it can be determined that the relay is not normally turned off. Therefore, the second controller 240 can determine that the relay 210 or the relay controller 212 has failed, or that the consumption current detector 230 has failed, and can generate the failure information according to the failure. The second controller 240 stores the generated failure information in the second memory 250 and transmits the generated failure information to the digital door lock 100, the user terminal 300, and the portable terminal 100 through the second bidirectional wireless communication unit 260 and the communication device 500, To the control server 400.

On the other hand, when there is a change in the sensed current amount as a result of the determination in ST330, that is, when the amount of current corresponding to the control signal generated by the second controller 240 is sensed, each component of the smart plug 200 waits while maintaining the operating state (ST350).
