Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 is a schematic structural diagram of a home network system 1 according to an embodiment of the present invention.

A home network system 1 according to an embodiment of the present invention includes a video phone 2 for outputting video and audio of the entrance door of a groove, a home network device 3 mounted on the video phone 2, A server 5 that manages data of the home IoT device 4 and a user terminal which receives data of the home IoT device 4 from the server 5 6).

The video phone 2 is installed in a room of a home and supports video and audio communication with a video phone of an entrance door or an apartment door. The video phone 2 opens the door through the button input of the user. The video phone 2 is upgraded to the home IoT device 4 with the home network device 3 mounted thereon. That is, the video phone 2 is included in the home IoT device 4.

The home network device 3 corresponds to a kind of adapter device installed in the video phone 2 and providing a home network service. The home network apparatus 3 mounted on the video phone 2 transmits video and audio information of the video phone 2 through a wireless communication function (e.g., Wi-Fi). Further, the home network apparatus 3 receives the remote command corresponding to the opening command of the door and transmits it to the video phone 2.

Here, the home network apparatus 3 has a gateway function and communicates data with a plurality of home I / O devices 4 in the home. The home network device 3 mediates intra-home data communication between the home IoT devices 4 according to the gateway function. Communication through which an intra-home AP (e.g., a wireless router) is mediated through intermediation of data communication. The data communication intermediation through which the in-home AP is mediated is a type of local breakout processing, which improves the communication speed and reduces the processing load on the server. For example, in the case of the local break-out process, the home network apparatus 3 transmits data of local communication (e.g., z-wave type) between the in-home IoT devices 4 to the in-home AP, And transmits the data to the device (4). The in-home AP provides local break-out communication services only to the IoT devices 4 registered in the home network device 3. [

The home IoT device 4 includes various devices and equipments such as home appliances, lighting, gas, electricity and the like, and there is no particular restriction. The device that transmits the operation state of the device through the wireless network and receives the remote command of the device corresponds to the home IoT device 4. The home IoT device 4 is capable of communicating data through the gateway function of the home network device 3 and communicating data with the server 5 via the in-home AP.

The server 5 receives the data of the home IoT device 4 and stores it as history information. A unique server 5 may be assigned to each of the home IoT devices 4. The server 5 provides information on the operating state of the home IoT device 4 at the request of the user terminal 6 and receives a remote command from the user terminal 6. [ The server 5 can lower the received remote command to the home IoT device 4 through the gateway function of the home network device 3 or to the home IoT device 4 via the in-home AP.

2 is a schematic internal configuration diagram of the home network apparatus 3 of FIG.

The home network apparatus 3 according to the embodiment of the present invention includes a signal input unit 31 for receiving video and audio signals of the video phone 2, a GW processing unit 33 for processing a gateway function, And a wireless communication unit (34).

Preferably, the home network apparatus 3 may further include an analog-to-digital (AD) signal converting unit 32.

The signal input unit 31 receives a video signal and a voice signal output from the video phone 2. [ For example, a videophone of a doorway captures an image of a doorway portion by user's button operation (for example, a doorbell), and receives a user's voice. In addition, the indoor video phone 2 requests transmission of video and audio signals to the entrance video phone by the user's request (e.g., button operation).

The AD signal converting unit 32 converts an analog signal into a digital signal. If the video phone is spherical, the video and audio signals are analog signals, and therefore conversion to a digital signal by the AD signal converter 32 is required.

The GW processing unit 33 processes a gateway function for various data received from the video phone 2 and the home IoT device 4. [ For the gateway function, the GW processing unit 33 registers the ID of the home IoT device 4. For processing of the gateway function, the GW processing unit 33 registers destination ID information corresponding to the registered ID and the state information of the home IoT device 4 and an instruction of a subsequent processing operation.

Here, the gateway function includes collection and classification of data. In accordance with the collection of the data, the GW processing unit 33 collects the data received from the home IoT device 4. In accordance with the classification of the data, the GW processing unit 33 inquires the information of the destination and the subsequent processing operation registered with the ID and status information of the collected data. The GW processing unit 33 performs the following processing operation to be inquired, and sets the inquired destination in the collected data. The destination includes the home IoT device 4 and the server 5.

Then, in the process of processing the gateway function, the GW processing unit 33 inquires information corresponding to the ID and the operation state collected from the first home IoT device 4. [ When information indicating the destination as the second home IoT device 4 is inquired, the GW processing section 33 uses the ID of the inquired second home IoT device 4 as a destination as a local control between the devices, And commands the IoT device 4 to perform a subsequent processing operation. In the subsequent processing operation, the GW processing section 33 may convert data received from the first home IoT device 4 and generate data to be transmitted to the second home IoT device 4. [

If the information corresponding to the ID and the operation state collected from the first home IoT device 4 is not retrieved, the GW processing unit 33 sets the destination to the server 5. [ Further, when a remote command for controlling the specific home IoT device 4 is collected from the server 5, the GW processing unit 33 is able to set the destination of the received remote command to the home IoT device 4. [

The wireless communication unit 34 transmits the data output from the GW processing unit 33 through the wireless network and transfers the data received through the wireless network to the input data of the GW processing unit 33. The input data correspond to data collected by the GW processing unit 33 by the gateway function.

The communication between the first home IoT device 4 and the second home IoT device 4 communicates with the first home IoT device 4 (internal communication or local communication) And the server 5 communicate by external communication. In the intra-home communication, the GW processing unit 33 processes the gateway function and integrally manages the plurality of home I / O devices 4. [ In-home communication replaces the processing load of the server 5.

FIG. 3 is an exemplary view illustrating the video and audio information of the video phone 2 received from the home network apparatus 3 of FIG. 1 on the screen of the TV terminal 401. FIG.

Here, the video phone 2, the TV terminal 401, and the TV set top box 402 correspond to the home IoT device 4. It is assumed that the doorbell is pressed and an output event occurs in the video phone 2. [ The visitor presses the buzzer of the video phone 201 at the common entrance (e.g., the first floor entrance of the apartment house) or the video phone 202 of the individual household door. The in-home video phone 2 receives image information and audio information according to the doorbell signal from the video phone 201 at the common entrance or the video phone at the entrance of the individual household.

When the home network apparatus 3 receives the video signal and the audio signal from the video phone 2, the home network apparatus 3 inquires the information set as the ID of the video phone 2 with respect to the input video signal and the audio signal. Information indicating the destination as a TV terminal 401 is searched using the ID as a key. The home network apparatus 3 wirelessly transmits the received video signal and audio signal to the TV terminal 401 when the TV terminal 401 is turned on in accordance with intra-home communication. On the other hand, the TV set top box 402 may receive the video signal and the audio signal from the home network device 3 and output it to the TV terminal 401. The TV terminal 401 outputs a pop-up screen on a TV screen in a PIP (Picture in Picture) manner, and outputs a video signal and a voice signal received through a pop-up screen. The user who is viewing the TV receives the visitor via the pop-up screen and issues an opening command to the corresponding entrance through the TV remote controller 7. The TV terminal 401 or the TV set top box 402 receives the remote control command and transmits the received command to the home network apparatus 3. [ The home network device 3 inquires the device ID and status information of the received command, sets the destination as the video phone 2 according to the inquired information, and sets the open command as a subsequent processing command. The home network device 3 outputs an open command to the video phone 2 and the video phone 2 issues a command to authorize the opening of the door.

The above example is an example of intra-home communication in which the TV terminal 401 or the TV set top box 402 is the first and second home IoT devices 4, respectively, for the videophone 2. Accordingly, it is apparent that the user can register various home automation commands based on the home network service in advance according to the opening and closing instructions of the door received through the video phone 2. [ In the case of the first entrance / exit within the user's home, home appliances, lights, boilers, etc. can be switched to the on-operation by the home automation command. Also, in the case of the user's last exit, it is possible to turn off the home IoT device 4 in the ON state or change the driving state by the home automation command.

4 is a schematic flow diagram of a home network method according to an embodiment of the present invention.

The user in the home mounts the home network apparatus 3 on the video phone 2. [ The user manipulates the user terminal 6 to register each home IoT device 4 integrated and managed in the home network device (S31). The corresponding ID is registered by the registration of the home IoT device 4. [

When the ID of the home IoT device 4 is registered, the user sets the ID of the destination home IoT device 4 to be processed by the gateway function and the subsequent processing command according to the collected status information of the ID (S32).

After the processing of the gateway function is registered, when an event of data reception is generated in the video phone 2, the home network apparatus 3 receives various signals from the video phone 2 (S33).

Further, when an event defined by the home IoT device 4 is generated, the home network device 3 receives the corresponding state data from the home IoT device 4 (S34).

When the home network device 3 receives the data, it processes the gateway function to inquire predetermined information using the source ID and the status data of the received data as a key, and designate a destination and a subsequent processing command according to the inquired information ( S35).

If the local communication is determined by the inquiry, the home network device 36 transmits a remote command with the home IoT device 4 as its destination (S36).

If the external communication is determined by the inquiry, the home network device 36 uploads the received data with the server 6 as a destination (S37). The server 6 can notify the state of the home IoT device 4 to the corresponding user terminal 6 when the uploaded data meets the notification condition according to the pre-registered notification setting.

The user terminal 6 accesses the server 6, inquires the operation status of the home IOT device 4, receives a remote command requested by the user, and issues a remote command to the server 6. The server 6 may then either issue a remote command to the home IoT device 4 via the intermediary of the home network device 36 for the received remote command or directly issue the remote command to the home IoT device 4 .

5 is a schematic flow chart of the home network apparatus 3 outputting the video and audio information of the video phone 2 to the TV terminal 401. Fig.

Here, the TV terminal 401 may include a TV set top box 402. In addition, since the TV terminal 401 is an example of the home IoT device 4, it goes without saying that the following steps are applied to the home IoT device 4.

When the TV terminal 401 is turned on, an application (WebApp) having a home IoT function is executed and detects a GW processing unit 33 of the home network apparatus 3 corresponding to the home hub through wireless communication to request a connection S401, S402).

In response to the connection request of the TV terminal 401, the home network apparatus 3 replies the connection address to the TV terminal 401 (S403).

In response to the connection address, the TV terminal 401 requests the socket connection to the home network apparatus 3 (S404), and the connection is made so that the TV terminal 401 and the home network apparatus 3 can perform data communication (S405).

Thereafter, when the doorbell signal is generated, the home network apparatus 3 receives the video signal and the audio signal according to the doorbell signal from the video phone 2 (S406).

When the doorbell signal is received, the home network apparatus 3 inquires processing information corresponding to the video phone 2 and the doorbell signal, sets the TV terminal 401 as a destination according to the inquired information, ) To inform subsequent processing of the doorbell signal (S407).

When the TV terminal 401 receives the doorbell signal, it executes the PIP application, receives the video and audio signals of the video phone 2 from the home network apparatus 3, and outputs the received signal through the PIP application S408).

When the TV terminal 401 receives the door open command by the user's remote control operation, the home network apparatus 3 receives an open command corresponding to the remote command from the TV terminal 401 (S409).

When the open command is received, the home network device 3 inquires information corresponding to the received open command, determines that the video phone 2 is an instruction to open the door according to the inquired information, The door open command is output (S410). The video phone 2 applies the opening to the door.

When the door is opened, the home network device 3 receives the data with the door open from the video phone 2 (S411).

When the opening data of the door is received, the home network apparatus 3 notifies the TV terminal 401 of the interruption of the transmission of video and audio signals, and the TV terminal 401 ends the PIP popup screen (S412).

In the above-described embodiment, the term "part" is not used as a term to denote the hardware division of the home network device 3. [ Accordingly, a plurality of constituent parts may be integrated into one constituent part, and one constituent part may be divided into a plurality of constituent parts. The constituent unit may mean a constituent part of hardware, but may also mean a constituent part of software. Therefore, it should be understood that the present invention is not particularly limited by the term "part ".

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It goes without saying that various modifications and variations are possible within the scope of equivalence of the scope.
