The driving unit 110 is formed on one side of the door 10 to allow the deadbolt 111 to be moved by an electric signal. The driving unit 110 includes an electric motor 112 and a deadbolt 111. The driving unit 110 may receive power from the external constant power supply through the deadbolt 111 or may receive power from the internal power supply 113 such as a removable battery. Herein, the internal power supply 113 may use a primary battery or a secondary battery. The deadbolt 111 has one side thereof formed of a rectangular parallelepiped member and a driving electrode 111-1 formed therein. The deadbolt 111 may be formed of an insulating high-strength synthetic resin material. The deadbolt 111 is advanced or withdrawn by the electric motor 112. When the deadbolt 111 is advanced, the deadbolt 111 is inserted into the bracket 20 formed in the door frame 11 to prevent the door 10 from opening. When the deadbolt 111 is withdrawn, the deadbolt 111 is separated from the bracket 20 and is drawn into the first body 101 to allow the door 10 to open.
In the case of the view (b), the door frame 11 is located to protrude from the plane of the door 10. Herein, the bracket 20 is installed in the second direction, which is arranged in an inner side of the door frame 11. The power board 31 is inserted into the bracket 20 in a direction perpendicular to the case of view (a), and the power board 31 is connected to the external adapter 30. The deadbolt 111 of the digital door lock 100 is drawn out from the first body 101 to be introduced into the bracket 20, and is in contact with the power board 31 to receive external power. In this way, the installation direction of the bracket 20 and the insertion position of the power board 31 are varied depending on the positions of the door 10 and the door frame 11, so that the installation is easy.
The inside of the bracket 20 includes a first seating groove 21-1, a second seating groove 22-1, a first wire groove 24, and a second wire groove 25. The first seating groove 21-1 is a groove in which the power board 31 is seated. The first seating groove 21-1 is formed in an inner partition wall to face the first insertion hole 21 so that the front tip of the deadbolt 111 is connected to the power board 31 when the deadbolt 111 is inserted through the first insertion port 21. The second seating groove 22-1 is another groove in which the power board 31 is seated. The second seating groove 22-1 is formed in an inner partition wall to face the second insertion hole 22 so that the front tip of the deadbolt 111 is connected to the power board 31 when the deadbolt 111 is inserted through the second insertion hole 22. Herein, the first seating groove 21-1 and the second seating groove 22-1 are formed orthogonal to each other.
The first wire groove 24 is a groove for fixing the electric wire of the adapter 30. The first wire groove 24 is formed on each of both inner sides of the bracket 20. This is to facilitate wiring of the electric wire of the adapter 30 according to the installation position of the bracket 20. The second wire groove 25 is another groove which is formed in one side of the bracket 20 to fix the electric wire. Accordingly, the first wire groove 24 and the second wire groove 25 are formed on the bottom surface of the bracket 20 so that wiring of the electric wire of the adapter 30 is possible in various positions. In addition, the first wire groove 24 and the second wire groove 25 may fix the electric wire of the adapter 30 to prevent the wire from being removed.
The detection unit 120 is implemented as a contact or non-contact sensor to sense whether the door 10 is opened or closed. When the detection unit 120 is implemented as a contact sensor, the detection unit 120 is formed to protrude to the outside of the first body 101. The detection unit 120 is provided in such a manner as to be in contact with the door frame 11 when the door 10 is closed, and not in contact with the door frame 11 when the door 10 is opened. The detection unit 120 senses whether the door 10 is opened or closed according to whether the door 10 is in contact with the door frame 11, and generates a detection signal for determining whether the digital door lock 100 receives power from an external power supply or an internal power supply 113 to output the same to the controller 230.
In addition, the detection unit 120 may be implemented as a non-contact sensor such as an infrared sensor, an illuminance sensor, and a magnetic sensor to sense whether the door 10 is opened or closed. In addition, the detection unit 120 may be formed with both the contact sensor and the non-contact sensor. For example, a first detection signal relating to whether the door 10 is opened or closed may be generated through the contact sensor, and a second detection signal relating to whether the door 10 is opened or closed may be generated through the non-contact sensor. This is to determine whether the detection unit 120 has a failure. When the first detection signal and the second detection signal are different from each other, such as a case that the first detection signal indicates a state in which the door 10 is open and the second detection signal indicates a state in which the door 10 is closed, or vice versa, it may be determined that the detection unit 120 has a failure.
The controller 130 is implemented as at least one microcontroller unit (MCU) on a circuit board. Herein, the controller 130 may be formed on the first body 101 or the second body 102. The controller 130 may move the deadbolt 111 according to an electric signal to control whether or not the door 10 is opened or closed. The controller 130 switches to receive power from an external constant power supply when the deadbolt 111 is drawn out of the main body and thus is in contact with the power board 31 inside the bracket 20 formed in the door frame 11. The controller 130 receives power from the internal power supply 113 when the deadbolt 111 is introduced into the body to be not in contact with the power board 31. Herein, the controller 130 shifts the voltage level of the electric signal when switching the power supply source between the constant power supply and the internal power supply 113, thereby preventing a power failure of the digital door lock 100.
In addition, the controller 130 outputs a failure signal when constant power is not supplied through the deadbolt 111 and power is not supplied from the internal power supply 113, in the case that the door 10 is closed. The controller 130 may determine whether the door 10 is opened or closed through the detection unit 120. Herein, even when the door 10 is closed, a failure signal is output when external constant power is not supplied. In addition, when the internal power supply 113 is configured as a rechargeable battery, a failure signal is output when the constant power is not charged to the internal power supply 113. The failure signal may be transmitted to the user terminal 40 or output as an alarm sound.
In addition, the controller 130 compares a first detection signal for detecting whether the door is open or closed through the detection unit 120, and a second detection signal for detecting whether a driving electrode 111-1 of the deadbolt 111 is in contact with the power terminal of the power board 31, and output a failure signal when the first signal and the second signal do not match with each other. The failure signal may be transmitted to the user terminal 40 or output as an alarm sound.
In addition, when the detection unit 120 is implemented with a contact sensor and a non-contact sensor, the controller 130 may output a failure signal even when the first detection signal of the contact sensor and the second detection signal of the non-contact sensor do not match with each other. The failure signal may be transmitted to the user terminal 40 or output as an alarm sound.
In addition, the controller 130 may check the power remaining amount state of the internal power supply. When the door 10 is closed, the controller 130 may send an electric signal to the internal power supply using a constant power supplied from the outside to determine the power remaining amount state. When the internal power supply is implemented as a secondary battery, the controller 130 may sense the deterioration of the charge/discharge performance. The controller 130 may identify the characteristic voltage for the internal power supply in the form of a secondary battery to determine the charging performance. The controller 130 may output a failure signal when the charging performance of the internal power supply in the form of a secondary battery is less than or equal to a predetermined value.
Meanwhile, the digital door lock 100 according to an embodiment of the present invention may further include a communication unit 140 and a sound unit 150.
The communication unit 140 communicates with an external user terminal 40 or a management server. The external user terminal 40 is a concept encompassing a fixed or mobile terminal used by a user. The communication unit 140 may output a detection signal relating to whether the door 10 is opened or closed to the user terminal 40 through a network, or may output information on the power remaining amount of the internal power supply 113 of the digital door lock 100. In addition, the communication unit 140 may acquire an indoor or outdoor image through the camera 104 formed in the first body 101 or the second body 102 and transmit the same to the user terminal 40. In addition, the communication unit 140 may receive a control signal remotely from the user terminal 40 and output the same to the controller 130. Accordingly, the user may remotely open/close the door lock 100 or check an indoor or outdoor situation.
The sound unit 150 detects surrounding sound. The sound unit 150 may identify an indoor or outdoor user through frequency analysis. The sound unit 150 operates in a sleep mode and, when a frequency of a predetermined amount or higher is detected, changes into a start mode to detect the frequency. The sound unit 150 may transmit the sound information to the external user terminal 40 through the communication unit 140. Herein, when the surrounding sound is detected, the controller 130 compares a frequency of the surrounding sound with that of a predetermined visitor's sound to identify information on the visitor and outputs the same to the external user terminal 40 or a management server. Herein, it is preferable that frequency information on sound of each visitor is preset in the user terminal 40 or the management server. Accordingly, it is possible to distinguish between a visitor and an internal resident from a remote location.
Meanwhile, the controller 130 receives at least one of a keypad input, a pattern input, and a question-and-answer input through the display unit 103 formed in the first body 101 or the second body 102 to provide a lock screen. When a code consisting of a combination of symbols and characters set by the user is input through the display unit 103, the controller 130 may unlock the digital door lock 100. When a gesture pattern set by the user is input through the display unit 103, the controller 130 may unlock the digital door lock 100. When a quiz in a question-and-answer format is provided through the display unit 103, and an answer is inputted from the user, the controller 130 may unlock the digital door lock 100. The lock screen may be randomly changed by the user. Since various lock screens may be provided, it is possible to reduce a risk of shoulder surfing by others and induce interest to the user.
In addition, the controller 130 may output an identification code through the display unit 103 formed in the first body 101 or the second body 102. Herein, the display unit 103 may be implemented as a touch display to output symbols, characters, figures, and the like. The controller 130 receives an identification code randomly changed at a predetermined period of time from the management server and outputs the identification code to the display unit 103 when the user terminal 40 approaches. The identification code may be implemented as a one-dimensional barcode, a two-dimensional barcode, or the like, but is not limited thereto. When the user terminal 40 obtains the identification code and thus is authenticated by the management server, the deadbolt 111 may be drawn into the body to release the lock state. Accordingly, the user may identify the user in such a manner as to directly input a password through the display unit 103 of the digital door lock 100 or in a non-contact manner without recognizing a fingerprint. The identification code is encrypted and managed by the management server, and the information is randomly changed at a predetermined period of time.
In addition, when the user's approach to the door is sensed using the human body sensor 106 formed in the first body 101 or the second body 102, the controller 130 may capture the user with the camera 104 formed in the first body 101 or the second body 102 and transmit the capturing result to the user terminal 40. The controller 130 detects infrared rays to check whether the user is approaching the door, and captures the human body of the user and transmits the capturing result to the user terminal 40 in a form of a push alarm. The controller 130 communicates with a remote camera formed indoors to allow a function of the camera 104 formed in the digital door lock 100 to be turned off and the indoor remote camera to be turned on when the door 10 is open. This is to monitor the indoor situation and persons entering and leaving the room through the remote camera 40, since the camera 104 of the digital door lock 100 cannot properly capture indoor situation when the door 10 is opened.
In addition, the controller 130 may access an external weather server, an Internet server, and the like to display life information such as weather information and schedule information on the display unit 103 of the digital door lock 100. Accordingly, when the user approaches the digital door lock 100, the human body sensor 106 detects the user's approach so that the user may check the current weather or schedule through the display unit 103. Herein, the controller 130 may be linked to external traffic information and the like to output the same to the display unit 103 of the digital door lock 100. The controller 130 may communicate with the user terminal 40 or may directly communicate with an external server to obtain public data such as weather information, schedule information, traffic information, and the like. The controller 130 may output such information as a voice through a speaker to notify the user of the information.
In addition, preset advertisement content may be exposed on the display unit 103 of the digital door lock 100. Herein, the advertisement content is changed at a predetermined period of time. The digital door lock 100 may expose the advertisement content when any person approaches the door. The advertisement content may be provided through the display unit 103 and a speaker. When the user attempts to unlock the door lock 100, the advertisement content is exposed first, and when the user has unlocked the door lock 100, predetermined points are accumulated to the account of the user terminal 40.

The communication unit 310 is capable of two-way communication with the door lock and the user terminal. A reward means such as points, coupons, and cash is paid to the account of the user terminal.
The detection information management unit 320 acquires detection information obtained by detecting the person's approach from the door lock. Herein, a motion detection sensor, a fingerprint sensor, a contact sensor, etc. capable of detecting the person's approach may be provided in the door lock, but the present invention is not limited thereto. The detection information management unit 320 detects in real time whether a person approaches the door lock. Accordingly, the advertisement information may be output to the display unit of the door lock when a person approaches. When detection information is acquired, the detection information management unit 320 outputs the detection information to the controller 340.
The advertisement information management unit 330 manages the advertisement information output to the display unit of the door lock. The advertisement information is content including at least one of a video, audio, and image uploaded by an advertiser. The advertisement information may be randomly output according to user setting or output in a customized manner to the user using the door lock. The advertisement information management unit 330 may update and provide the advertisement information when the user's approach is detected and the door lock is unlocked. The advertisement information management unit 330 may change and provide the advertisement information according to the location where the door lock is installed, the time when the door lock is installed, the user who installs the door lock, and the like.
In addition, when the user requests additional information about the advertisement information, the advertisement information management unit 330 may provide a URL for providing the additional information to the user terminal. The URL is to provide the additional information because the time when the advertisement information is displayed through the door lock is short. For example, an interface for requesting the additional information may be included in the advertisement information. When the user clicks the interface, a URL of the additional information may be provided to a preset account of the user terminal through SMS, LMS, and SNS. The user may check the additional information through the URL link.
The controller 340 controls the display unit in such a manner as to output preset advertisement information. The advertisement information is determined on the basis of location information of the door lock. The controller 340 may use location information of a network subscription network to which the corresponding door lock belongs, or recognize location information based on an address value input from an application installed in the user terminal. Herein, the location information of the door lock may be set in such a manner that detailed address information is not input to protect personal information.
The controller 340 designates nearby advertisers and outputs the corresponding advertisement information according to the location information of the door lock. Herein, the controller 340 may be set in such a manner as to automatically output the advertisement information according to the location information to the door lock. The controller 340 may receive user information from a user terminal to correspond the user information to the advertisement information on the basis of user's gender, age, and preference information. For example, in the case of a student, advertisement information related to education may be displayed, such as an academy advertisement.
In addition, the controller 340 compares the first location information of the door lock with the second location information of the user terminal. The controller 340 designates the advertisement information on the basis of the first location information, when the first location information and the second location information are within a predetermined range. Meanwhile, the controller 340 may designate the advertisement information on the basis of the second location information when the first location information and the second location information are not within the predetermined range. This is to more accurately set the location information of the door lock when the network is unstable.
In addition, the controller 340 may analyze the user's preference by performing data mining on the usage record of the user terminal, and update the advertisement information according to the preference. Herein, it is possible to classify a type of a product that the user prefers by analyzing the user's Internet search record, call record, etc. through an application installed in the user terminal. The controller 340 may designate an advertisement associated with a product that the user prefers to be output to the door lock as advertisement information.
In addition, the controller 340 outputs a lock screen to the display unit when a user attempts to unlock the door lock. Herein, the user may be allowed to output the lock screen using a touch sensor or a contact sensor provided in the door lock. The lock screen may be automatically output after the advertisement information ends. The lock screen may be in the form of a number key input or a touch pattern input, but is not limited thereto. For example, the lock screen may be implemented as an interface capable of recognizing a user's fingerprint, voice, iris, or face.
In addition, the controller 340 may output an identification code on the lock screen. The identification code is formed in the type of a barcode, a QR code, and an AR code, but is not limited thereto. When the user terminal acquires an identification code and transmits the same together with the authentication information, the controller 340 performs a validity check on the identification code and authentication information. The controller 340 unlocks the door lock when the identification code and authentication information transmitted from the user terminal are valid. Here, the authentication information may include a unique identification number of the user terminal, a mobile communication number, and fingerprint information. Accordingly, the user may unlock the door lock without entering a password into the door lock, thereby reducing the risk of shoulder surfing and enhancing security.
In addition, the controller 340 is also capable of linking the advertisement information of the door lock to the user terminal. For example, when the advertisement information of the door lock is terminated and the door lock is unlocked, the advertisement information is output to the user terminal of a user who is approaching. In the case of an advertisement of 1 minute, when the user is capable of performing the unlocking procedure in 5 seconds, the advertisement of the remaining 55 seconds may be transmitted to the user terminal so that the user is capable of continuously viewing. Accordingly, even when the advertisement is exposed to the door lock for a short time, the advertisement may be continuously exposed to the user terminal.
Meanwhile, the digital door lock control server 300 according to an embodiment of the present invention may further include a reward unit 350.
The reward unit 350 pays a preset reward means to a user account of the door lock according to the number of times that the advertisement information is provided. Here, the reward means comprehensively includes any form capable of being used for money, such as cash, points, coupons, and virtual currency. The reward unit 350 counts the number of times the advertiser's advertisement information is output from the corresponding door lock, and differentially pays the reward means. For example, as the number of times the advertisement information is output increases, a total amount paid as the reward means increases. Herein, the reward unit 350 is connected to an external financial server, an Internet server, and the like.
Herein, the controller 340 pays a predetermined fee to the user account of the door lock when the advertisement information is terminated and the lock screen is released. The controller 340 may perform a validity check to detect whether the advertisement information is effectively output from the corresponding door lock. For example, when the door lock is unlocked within a predetermined time after the advertisement information is displayed, the payment of the reward means may be canceled. Accordingly, it is possible to avoid a situation where the advertisement information is just displayed on the door lock without the user actually watching the advertisement information.
In addition, the controller 340 may differentially pay the reward means according to the time that the advertisement information is output. For example, in the case of an advertisement for 1 minute, points are differentially paid, such as 10 points when the unlocking procedure is performed within 5 seconds, 20 points for 6-30 seconds, 30 points for 31-60 seconds, and so on. The controller 340 may pay an additional reward means when the advertisement information is continuously output in the user terminal, in the case that some of the advertisement information is transmitted to the user terminal so that the user is capable of continuous viewing. This is to compensate a case that the advertisement is briefly exposed in the door lock but the user additionally views the advertisement through the user terminal.
Meanwhile, the digital door lock control server 300 according to an embodiment of the present invention may further include an analysis unit 360. The analysis unit 360 may generate analysis information on the number of times the advertisement information is viewed and the location where the advertisement information is viewed and provides the analysis information to the advertiser. The analysis unit 360 may generate an electronic map to display and provide exposure information of advertisement information for each location. In this case, the analysis unit 360 may generate analysis information by corresponding the position where the door lock is installed to order information of the advertiser's advertisement product. For example, in the case of Pizza A, using analysis information, such as the number of advertisement exposures in apartment B is 50 times a day, and the order quantity is 10 times a day before the advertisement and 20 times a day after the advertisement, it may be determined whether the advertising information actually leads to an increase in sales.
Meanwhile, the digital door lock control server 300 according to an embodiment of the present invention may further include a game unit 370. The game unit 370 may output game information on the lock screen to induce the unlocking procedure. For example, the game information may be implemented in various forms such as common sense of current affairs, English problems, math problems, quizzes, and hidden objects. The game information may be set by the user through the user terminal. This may be set by a user who has a representative administrator authority among members. After the advertisement information is output, the game information is displayed on the lock screen, and when the mission is completed, the door lock is unlocked. For example, in the case that the game information is output in the form of a quiz “What date is the wedding anniversary?”, the door lock is unlocked when the user enters the date using the keypad. Accordingly, the user may be interested in unlocking the door lock.
