DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Certain exemplary embodiments are described in greater detail below with reference to the accompanying drawings.
In the following description, like drawing reference numerals are used for like elements, even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of exemplary embodiments. However, exemplary embodiments can be practiced without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the application with unnecessary detail.
FIG. 1 is a block diagram illustrating a structure of a door lock apparatus according to an exemplary embodiment.
According to FIG. 1, a door lock apparatus 100 may include a first interface 110, a near field communication unit 120 (e.g., a near field communicator), a second interface 130, and a controller 140.
The door lock apparatus 100 refers to an apparatus which opens and closes a sliding door, a hinged door and the like automatically by an opening and closing mechanism, performs authentication by using various means such as an electronic card, fingerprint recognition, iris recognition, authentication number input, and the like, and automatically opens and closes a door when the authentication is performed.
The door lock apparatus 100 is disposed on both sides of an entrance door, and thus, the door lock apparatus 100 according to an exemplary embodiment may perform a function of a relay station for relaying communication between devices that are outside and inside of a house.
The first interface 110 may communicate with a plurality of external apparatuses. To be specific, in order to communicate with a plurality of external apparatuses, the first interface 110 may communicate with various external apparatuses (for example, another apparatus or server), which are connected to a network, by using a network address allocated to the door lock apparatus 100.
In addition, the first interface 110 may perform network communication by using various communication methods. To be specific, the first interface 110 may perform network communication by using various communication methods such as a wired/wireless Local Area Network (LAN), Wi-Fi, a Wide Area Network (WAN), Ethernet, Bluetooth, Zigbee, a Universal Serial Bus (USB), IEEE 1394, etc. The first interface 110 may be equipped with various communication modules for performing the network communication according to each communication method.
For example, when communication is to be performed by a wired LAN method, the first interface 110 may be equipped with a wired LAN card, and when communication is to be performed by a Wi-Fi method, the first interface 110 may be equipped with a Wi-Fi communication chip.
The near field communication unit 120 may perform authentication for opening a door.
Herein, the near field communication unit 120 may perform the authentication by performing near field communication with a mobile device (not shown) and recognizing a tag within the mobile device.
For example, the near field communication unit 120 may use a Near Field Communication (NFC) method in order to perform the near field communication with a mobile device (not shown). The NFC method may use one of Radio Frequency Identification (RFID) technologies, and may be a non-contact type communication technology which may use a frequency band of 13.56 MHz. The NFC method is a next-generation communication technology which receives attention due to its high security level and inexpensive costs based on its short communication distance.
In particular, the NFC method is capable of using both of a function of reading data and a function of writing data, and thus, does not require a dongle (a reader) which was needed to use the RFID technology. In addition, the NFC method is similar to the existing near field communication methods such as a Bluetooth method, etc., but is not required to establish a particular setting between devices, unlike the Bluetooth method.
Accordingly, the near field communication unit 120 may be provided with an NFC chip, and when a mobile device including other NFC chip or an NFC card is located within a predetermined range of the near field communication unit 120, may perform authentication by exchanging data with the mobile device.
The second interface 130 may communicate with a display apparatus. Herein, the display apparatus (not shown) may be implemented as various types of electronic apparatus such as a television (TV), a smart phone, a tablet personal computer (PC), a desktop PC, a laptop PC, etc.
In addition, as described above in connection with the first interface 110, the second interface 130 may perform the network communication by using various communication methods. Thus, redundant descriptions will be omitted.
When authentication is performed, the controller 140 may control to receive status information on each of a plurality of external apparatuses from the plurality of external apparatuses, transmit the received status information to a display apparatus, and display the transmitted status information.
In particular, when the authentication for opening a door is performed by the near field communication unit 120, the controller 140 may control the first interface 110 to receive the status information on each of the plurality of external apparatuses by communicating with the plurality of external apparatuses, and may control the second interface 120 to transmit the received status information to the display apparatus to be displayed.
Accordingly, in order to control the display apparatus to display the received status information, the controller 140 may add and transmit a control signal for displaying the received status information on the display apparatus to the received status information as a form of meta data.
FIG. 2 is a view for explaining operations of a door lock apparatus according to an exemplary embodiment.
Referring to FIG. 2, when a mobile device 220 including an NFC chip for performing the authentication when being tagged with a door lock apparatus 210 approaches within a predetermined range, the controller 140 of the door lock apparatus 210 performs the authentication for opening a door, and when the authentication is performed, may receive status information on each of a plurality of external apparatuses 240 from the plurality of external apparatuses 240.
In addition, the controller 140 of the door lock apparatus 210 may control to transmit the received status information to a display apparatus 230 and display the transmitted status information.
For example, when a user brings the mobile device 220 including an NFC chip for performing authentication by being tagged with the door lock apparatus 210 within a predetermined range of the door lock apparatus 210 in order to enter a house, the controller 140 performs the authentication for opening a door, and may receive information on electricity consumption amount measured by an electricity meter.
In addition, the controller 140 may control to transmit the information on the electricity consumption amount received from the electricity meter and display the information. Thus, the user is able to know the electricity consumption amount as shown in the electricity meter through the display apparatus 230 without checking the electricity meter.
The display apparatus 230 may be the mobile device 220 including an NFC chip for performing the authentication by being tagged with the door lock apparatus 210. In this case, the mobile device 220 may perform the authentication with the door lock apparatus 230, and receive and display the status information on each of a plurality of external apparatuses from the door lock apparatus 230 after the authentication is performed. Those operations will be described in detail by referring to FIG. 3.
FIG. 3 is a view for explaining operations of a mobile device according to an exemplary embodiment.
Referring to FIG. 3, when a mobile device 320 including an NFC chip for performing the authentication by being tagged with a door lock apparatus 310 approaches within a predetermined range, the controller 140 of the door lock apparatus 310 may perform the authentication for opening a door, and when the authentication is performed, may receive the status information on each of a plurality of external apparatuses 330 from the plurality of external apparatuses 330.
In addition, the controller 140 of the door lock apparatus 310 may control to transmit the received status information to the mobile device and display the received status information.
That is, a user is able to perform the authentication by tagging the mobile device 320 with the door lock apparatus 310, and when the authentication is performed, is able to check the status of each of the plurality of external apparatuses 330 through a screen of the mobile device 320.
Although the aforementioned exemplary embodiment was described by taking the mobile device 320 including the NFC chip for performing the authentication by being tagged with the door lock apparatus 310 as an example, a card where the NFC chip is embedded may be separated from the mobile device 320.
That is, the user is able to perform the authentication by tagging the mobile device 320 with the door lock apparatus 310 by using a card where the NFC chip is embedded, and when the authentication is performed, the controller 140 of the door lock apparatus 310 may control to transmit the status information on each of the plurality of apparatuses to the mobile device 320 and display the status information.
In addition, the door lock apparatus 310 may further include a plurality of keys. Hence, when an authentication number is input through the plurality of keys, the near field communication unit 120 may perform the authentication by comparing the input authentication number and a pre-stored authentication number.
For example, when a user inputs an authentication number by using the plurality of keys mounted on the door lock apparatus 310 without performing the authentication by tagging the mobile device with the door lock apparatus by using the card where the NFC chip is embedded, the controller 140 of the door lock apparatus 310 may perform the authentication by comparing the authentication number input through the plurality of keys and the pre-stored authentication number, and when the authentication is performed, may control to receive the status information on each of the plurality of external apparatuses 330 from the plurality of external apparatuses 330 as specified above, transmit the received status information to the display apparatus 230 or the mobile device 320 and display the status information.
Hence, when a door lock apparatus is equipped with both of a near field communication unit which performs the authentication by a tagging operation and a plurality of keys, a user is able to perform the authentication selectively, and when the authentication is performed, the user is able to check the status of each of a plurality of external apparatuses through a display apparatus or a mobile device.
The plurality of external apparatuses 330 may include at least one of a first external apparatus which is disposed in an external environment of a space defined by a door where a door lock apparatus is mounted and a second external apparatus which is disposed in an internal environment of the space. Those external apparatuses will be described in detail by referring to FIG. 4.
FIG. 4 is a view of a plurality of external apparatuses according to an exemplary embodiment.
Referring to FIG. 4, a space 420 defined by a door 410 where a door lock apparatus is mounted may refer to an internal space of a house.
In addition, an external environment of the space 420 defined by the door 410 where a door lock apparatus may refer to an external space of a house.
Accordingly, a plurality of external apparatuses 430 which are located in the space 420 defined by the door 410 where a door lock apparatus is mounted, that is, an internal space of a house is a second external apparatus, and a plurality of external apparatuses 440 which are located in an external environment of the space 420 defined by the door 410 where a door lock apparatus is mounted, that is, an external space of the house is a first external apparatus.
As shown in FIG. 4, a plurality of external apparatuses 430 which are located in the internal space of a house, that is, the second external apparatus may be a TV, a stereo system, a washing machine, a gas stove, etc., and a plurality of external apparatuses 440 which are located in the external space of a house, that is, the first external apparatus may be a car, a sprinkler, a closed circuit television (CCTV), etc.
Herein, a display apparatus which receives the status information on the plurality of external apparatuses 430 and 440 from the door lock apparatus and displays the received status information may be an apparatus which is disposed in the internal environment of the space 420 defined by the door 410 where the door lock apparatus is mounted.
For example, in FIG. 4, the display apparatus which receives the status information on the plurality of external apparatuses 430 and 440 from the door lock apparatus and displays the received status information may be a TV.
When the display apparatus is a TV, a user is able to perform the authentication by using an NFC card or by inputting an authentication number through the plurality of keys mounted on the door lock apparatus, and the TV may receive the status information on each of the plurality of external apparatuses 430 and 440 from the door lock apparatus. When the received status information is transmitted to the TV, the TV may display the status of each of the plurality of external apparatuses.
Herein, the display apparatus was described by taking a TV as an example, but not limited thereto, the display apparatus according to an exemplary embodiment may be implemented as an electronic apparatus which is capable of displaying the status of each of a plurality of external apparatuses based on the received status information.
In addition, although not illustrated in FIG. 4, the display apparatus which receives the status information on the plurality of external apparatuses 430 and 440 from the door lock apparatus and displays the received status information may be a mobile device.
When the authentication is performed, the controller 140 may request for the status information to each of the plurality of external apparatuses and receive the status information.
To be specific, the controller 140 may perform the authentication by recognizing an NFC card in the mobile device through the near field communication with the mobile device, or when the authentication is performed through the authentication number input by the plurality of keys mounted on the door lock apparatus 100, the controller 140 may request for the status information to each of the plurality of external apparatuses, and receive the status information from each of the plurality of external apparatuses.
Herein, the controller 140 may request for the status information to each of the plurality of external apparatuses and receive the status information only after the authentication is performed by the near field communication unit 120. At this time, the controller 140 may control to transmit the received status information to the display apparatus or the mobile device and display the transmitted status information.
For example, when the near field communication unit 120 recognizes the NFC card in the mobile device, an authentication condition is satisfied, and the authentication is performed, the controller 140 may transmit a signal to request for the status information on each of the plurality of external apparatuses by a confirmation signal which shows that the authentication condition is satisfied triggering the first interface.
In addition, the door lock apparatus 100 may further include a storage configured to store the status information. Such configuration of the door lock apparatus 100 will be described by referring to FIG. 5.
FIG. 5 is a block diagram of a structure of a door lock apparatus according to an exemplary embodiment.
Referring to FIG. 5, a door lock apparatus 500 may include a first interface 510, a near field communication unit 520, a second interface 530, a storage 540, and a controller 550.
The first interface 510, the near field communication unit 520, the second interface 530, and the controller 550 were described above, and thus, the detailed description is omitted.
When the door lock apparatus 500 includes the storage 540, the controller 550 may receive the status information from a plurality of external apparatuses at a predetermined time interval and store the received status information in the storage 540.
To be specific, the controller 550 may update the status information by receiving the status information from the plurality of external apparatuses at a predetermined time interval and storing the status information in the storage 540 even when the authentication is not performed in the near field communication unit 520.
In this case, the user is able to see the status of each of the plurality of external apparatuses by receiving the status of each of the plurality of external apparatuses, which is updated to the storage 540 through the communication between the mobile device and the door lock apparatus 500 without performing the authentication.
In addition, in case of updating the status information by receiving the status information from the plurality of external apparatuses and storing the status information in the storage 540, when the near field communication unit 520 performs the authentication, the controller 550 may receive the status information by requesting for the status information to each of the plurality of external apparatuses.
The plurality of external apparatuses may include at least one of a car, an electricity meter, a sprinkler, an air-conditional and heating system, and a home appliance.
