There is a problem that integrated and intuitive management of home devices is not easy.

Published Patent No. 10-2012-0014076

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-mentioned problems of the related art, and it is an object of the present invention to provide a home device which can always control home devices provided in the home even outside the home, And a control method therefor, a home device included in the home system, and a control method thereof.

According to another aspect of the present invention, there is provided a method of controlling a home device control system including a cloud server, a router, and a home device, the method comprising: causing the home device to generate UDP hole punching corresponding to the cloud server in the router UDP packet, and when it is determined that UDP hole punching corresponding to the cloud server has not been generated in the router based on the communication state with the cloud server, a long polling TCP response is requested to the cloud server Transmitting a long polling TCP request signal; And the cloud server communicates with the home device via at least one of UDP communication and TCP communication via the router.

In order to achieve the above-mentioned object, a control method of a home device communicating with a cloud server via a router according to the present invention comprises: transmitting a UDP packet for causing UDP hole punching corresponding to the cloud server to be generated in the router ; Determining whether UDP hole punching corresponding to the cloud server is generated in the router based on a communication state with the cloud server; And a step of transmitting a long polling TCP request signal for requesting a long polling TCP response to the cloud server when it is determined that the UDP hole punching corresponding to the cloud server is not generated in the router .

In order to achieve the above object, a home device control system including a cloud server, a router, and a home device according to the present invention is characterized in that the cloud server communicates with the home device via UDP (User Datagram Protocol) Wherein the home device transmits a UDP packet for causing a UDP hole punching corresponding to the cloud server to be generated in the router, and a communication state with the cloud server And a long polling TCP request signal for requesting a long polling TCP response to the cloud server when it is determined that UDP hole punching corresponding to the cloud server has not been created in the router based on the long polling TCP request signal .

In order to achieve the above object, a home device communicating with a cloud server via a router according to the present invention comprises: a receiver for receiving a control signal from the cloud server; A transmitting unit transmitting at least one of a request signal and a response signal to the cloud server; A UDP packet for causing a UDP (User Datagram Protocol) hole punching corresponding to the cloud server to be generated in the router is transmitted through the transmission unit, and the UDP packet is transmitted to the cloud server based on a communication state with the cloud server And a controller for controlling a long polling TCP request signal requesting a long polling TCP response to the cloud server when it is determined that a corresponding UDP hole punching has not been generated.

As described above, according to the present invention, a home device provided in a home can be controlled using an Internet network even outside the home using a user terminal.

In particular, when the UDP hole punching is not generated in the router, the home device preferentially controls the UDP communication with the cloud server. In this case, TCP communication with the cloud server is performed secondarily, thereby reducing the load on the server. The connection can be made even under the network condition.

Furthermore, since the user terminal can access the cloud server and collectively check the status of home home devices, the inconvenience of directly connecting to the home device each time is reduced.

FIG. 2 is a functional block diagram of the home device of FIG. 1,
FIG. 3 is a view showing an example of a router and the control dongle connected thereto in FIG. 1,
FIG. 4 and FIG. 5 are control flowcharts of a home device control system according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, embodiments of the present invention will be described in order to facilitate understanding of the present invention, and the present invention is not limited to these embodiments. In particular, the present invention can be configured by combining at least any one of individual components, individual functions, or individual steps included in each embodiment.

Hereinafter, each signal referred to in the embodiments of the present invention may refer to one signal transmitted by one connection or the like, but may also mean a series of signals transmitted for the purpose of performing a specific function . That is, in each embodiment, a plurality of signals transmitted after a predetermined time interval or after receiving a response signal from the counterpart device can be represented by a single signal name for convenience.

The home system 100 control system according to an embodiment of the present invention includes a cloud server 400, a router 200, a home device 100, and a user terminal 300 as shown in FIG. 1 .

Here, the cloud server 400 communicates with the home device 100 via a router 200 using at least one of UDP (User Datagram Protocol) communication and TCP (Transmission Control Protocol) communication. The home server 100 And transmits a control signal to the home device 100 when a control signal transmission event is detected. The home device 100 transmits the control signal to the home device 100 when the control signal transmission event is detected.

For example, if there is a control request from the user terminal 300, the cloud server 400 may transmit a control signal corresponding to the control request to the corresponding home device 100.

This control signal can be transmitted by UDP communication or TCP communication as described above.

For example, if UDP hole punching is generated in the router 200 as described later and the UDP communication with the home device 100 is possible, the cloud server 400 performs UDP communication with the home device 100, The UDP communication with the home device 100 can be performed.

To this end, the cloud server 400 may transmit a UDP packet for causing the router 200 to generate UDP hole punching when the connection of the home device 100 is detected.

Here, UDP hole punching means that a communication port is opened to allow a UDP packet to be transmitted. In order to generate a UDP hole punching in a predetermined gateway device (the router 200 in this embodiment), UDP packets are transmitted And the process of generating the UDP hole punching in the corresponding gateway device per se corresponds to the known technique, so that a detailed description thereof will be omitted.

The cloud server 400 also transmits a long polling TCP response signal to the home device 100 when the long polling TCP request signal is received from the home device 100. [

Here, the long polling TCP response signal is transmitted by maintaining the waiting state for a predetermined time (for example, 90 seconds), and when there is no control signal to be transmitted during that period, the home terminal 100 transmits a control end signal to the home device 100 .

That is, when a control signal transmission event is detected within a predetermined time after the long polling TCP request signal of the home device 100 is received, the cloud server 400 immediately transmits a control signal corresponding to the control signal transmission event to the home device 100 100, and if a control signal transmission event is not detected within the set time, a control end signal is transmitted to the home device 100 at a predetermined time.

That is, when the UDP communication with the home device 100 is possible, the cloud server 400 transmits a control signal in a UDP packet, and when the TCP session is established according to the long polling TCP request signal to the home device 100 If there is a control signal to be transmitted to the corresponding home device 100 within a predetermined time, the control signal is transmitted immediately. Otherwise, the control end signal is transmitted at a time point when the preset time ends.

Here, the TCP communication between the home device 100 and the cloud server 400 may be a communication based on HyperText Transfer Protocol (HTTP).

In order to control the above-described home devices 100, the cloud server 400 is provided with user information (e.g., a user ID) and information about each home device 100 (for example, a serial number or a MAC Address information, etc.) of the home device 100 must be matched in advance, and information about the router 200 to which each home device 100 is connected (for example, the router 200) IP address) must be registered.

It is needless to say that the cloud server 400 may be constituted by a plurality of physically distinct servers.

The router 200 is a kind of gateway provided in the home, and plays a role of relaying the home devices 100 and the cloud server 400 so that they can communicate with each other.

The router 200 can also communicate with the user terminal 300 to be described later so that the user terminal 300 can communicate with the home device 100 or the cloud server 400 via the router 200. [

For example, when it is assumed that the router 200 corresponds to a Wi-Fi access point, the router 200 and the home device 100 can communicate with each other through a wired or wireless connection, The communication by the method can be performed.

It is preferable that the wireless communication is established between the router 200 and the user terminal 300.

The router 200 can generate UDP hole punching according to a UDP packet received from at least one of the home device 100 and the cloud server 400 as described above. In this case, the home device 100 and the cloud server 400, Lt; RTI ID = 0.0 > UDP < / RTI >

The home device 100 refers to all devices that are provided in the home and can be controlled by the user from the outside by using the user terminal 300 as described later. For example, the home device 100 may be connected to a lamp, An apparatus capable of operating, a device connected to a gas valve to perform opening and closing operations with a gas valve, and a device connected to a television and performing power on / off of the television.

Each of the home devices 100 is configured to be able to communicate with an access point as described above. In particular, the home device 100 transmits a UDP packet for generating a UDP hole punching corresponding to the cloud server 400 to the router 200 And performs TCP communication with the cloud server 400 when it is determined that the corresponding UDP hole punching has not been generated in the router 200. [

An example of a detailed functional block of such a home device 100 is shown in FIG.

As shown in the figure, each home device 100 may include a receiving unit 110, a transmitting unit 120, and a controller 130.

Here, the receiving unit 110 receives a control signal from the cloud server 400, and the transmitting unit 120 transmits a response signal including a processing result according to the control signal or a specific request signal to the cloud server 400, As shown in FIG.

The control unit 130 controls the UDP packet to be generated in the router 200 so that the UDP hole punching corresponding to the cloud server 400 is transmitted through the transmission unit 120. [

When the controller 130 determines that the UDP hole punching corresponding to the cloud server 400 is generated in the router 200 based on the communication state with the cloud server 400, the controller 130 performs UDP communication with the cloud server 400 If it is determined that UDP hole punching corresponding to the cloud server 400 has not been generated in the router 200 based on the communication state with the cloud server 400, a long polling TCP request is sent to the cloud server 400 So that the signal is transmitted.

Here, the long polling TCP request signal is a signal requesting the long polling TCP response to the cloud server 400.

For example, when the UDP packet is not received from the cloud server 400 within a predetermined time after the UDP packet is transmitted to the cloud server 400 to generate the UDP hole punching in the router 200 It can be determined that UDP hole punching is not generated in the router 200. [

When it is determined that UDP hole punching is not generated in the router 200, the controller 130 transmits a long polling TCP request signal to the cloud server 400 to enable TCP communication with the cloud server 400.

The control unit 130 performs a control function corresponding to the control signal when the control signal is received from the cloud server 400. For example, when the home device 100 of the present embodiment is integrally formed with the electric lamp, The flashing switching operation of the lamp can be performed.

Alternatively, when the home device 100 of the present embodiment is not integrally formed with the electric lamp but is connected by a cable for transmission of a switching signal, the controller 130 may transmit a switching signal corresponding to the control signal through the cable It is.

As another example, when the received control signal is a status information request for the home-device 100, the controller 130 transmits status information of the home-device 100 (e.g., information related to sensing information or operation status) Or may be transmitted to the server 400.

As described above, the control signal can be received by UDP communication or TCP communication. In particular, when the control signal is received as a TCP packet, the control unit 130 receives a control corresponding to the control signal, A TCP request signal may be transmitted to the cloud server 400 or a new long polling TCP request signal may be transmitted to the cloud server 400 when a control end signal is received from the cloud server 400. [

When the home devices 100 communicate with the cloud server 400, the state information of the home device 100 is transmitted to the cloud server 400 at a specific time or at a time when the request is received from the cloud server 400, So that the plurality of home devices 100 can be integrally managed.

The user terminal 300 accesses the cloud server 400 to check the status of each home device 100 provided in the home and controls each home device 100.

For example, the user terminal 300 can access the cloud server 400 via a base station outside the home.

That is, the user can simultaneously check the state information of the home devices 100 provided in the home using the user terminal 300, for example, in the form of an integrated list, select one of them, It can be done.

The cloud server 400 transmits a control signal to the home device 100 according to the control command of the user terminal 300 as described above.

For this purpose, the information about the home device 100 provided in the home should be registered in the cloud server 400 in advance.

The user terminal 300 receives the device information from the home device 100 via the router 200 and controls the home device 100 only when the received device information is registered in the cloud server 400 The information related to the home device 100 may be registered in the cloud server.

For example, when users buy the home device 100, the unique number (serial number or MAC address, etc.) of the home device 100 is matched with the user information (e.g., ID, etc.) in the cloud server 400 When the unique number received from the home device 100 matches the user ID and is already registered in the cloud server 400, the user terminal 300 can access the router 200 connected to the home device 100 The IP address or the MAC address of the mobile terminal 400 can be registered in the cloud server 400.

If the user terminal 300 compares the device information of the home device 100 with the device information stored in the cloud server 400, it is possible to prevent illegal use by the user who has acquired the home device 100 in a non- can do.

Although the user terminal 300 directly communicates with the home devices 100 to acquire the device information in the above embodiment, if the router 200 is provided with a separate control dongle 500, The terminal 300 can acquire the device information of the home device 100 using the control dongle 500.

That is, the user terminal 300 receives the device information about the home device 100 from the control dongle 500, and the device information about the home device 100 received from the control dongle 500 is transmitted to the cloud server 400. [ The information related to the home device 100 for the control of the home device 100 can be registered in the cloud server 400 only when it is registered in the cloud server 400. [

In this case, the information related to the home device 100 for controlling the home device 100 may further include not only the IP address of the access point but also various information (such as a serial number or internal IP information) about the control dongle 500 .

This is for distinguishing between a plurality of control dongles 500 connected to the router 200.

An example of such a control dongle 500 is well illustrated in FIG. That is, the control dongle 500 may be configured to be mounted on a predetermined port of the router 200 as shown in FIG.

The control dongle 500 maintains the communication state through the pairing process with each home device 100 on behalf of the user terminal 300 in the embodiment described above and receives the device information from each home device 100, And transmits the control signal received from the cloud server 400 to each home device 100. The communication process between the control dongle 500 and each home device 100 Corresponds to a known technique, and thus a detailed description thereof will be omitted.

It is needless to say that the control dongle 500 and the router 200 may be integrally formed.

Hereinafter, a control flow of the control system of the home-device 100 according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5. FIG.

First, a process of registering information related to the home device 100 in the cloud server will be described with reference to FIG. In this embodiment, since the control dongle 500 is directly connected to the access point (i.e., the router 200), it is assumed that the control dongle 500 is a single device for convenience.

The user terminal 300 requests access point information and control dongle information (step S1), and receives access point information and dongle information from the access point 200 and the control dongle 500 (step S3). For example, a serial number of the access point 200, a MAC address, an IP address, a serial number of the control dongle 500, and the like.

The user terminal 300 requests the control device 500 of the home device 100 in step S5 and the control dongle 500 transmits the device information of the home device 100, (E.g., device ID, device name, serial number, etc.) to the user terminal 300 (step S7).

Meanwhile, the user terminal 300 transmits the user ID input by the user (step S9) to the cloud server 400 and requests the device information list (step S11).

The cloud server 400 transmits the device information list matched with the user ID to the user terminal 300 (step S13).

The user terminal 300 compares the device information received from the control dongle 500 with the device information list received from the cloud server 400 and determines whether the subscription information matches the subscription information (step S15).

That is, when the device information received from the control dongle 500 is included in the device information list received from the cloud server 400, the user terminal 300 determines that the corresponding home device 100 is normally subscribed, that is, It is judged to be an authorized device.

The user terminal 300 transmits the information related to the home device 100 (the IP address of the access point 200, the private IP information of the control dongle 500, the control dongle 500 ) To the cloud server 400 (step S17).

Accordingly, the cloud server 400 registers information related to the home device 100, and if the user terminal 300 makes a request from the user terminal 300, the cloud server 400 can permit the control only on the home device 100 to which the related information is registered.

That is, it is possible to prevent a user who has illegally acquired the home device 100 from using the home device 100 by not granting the control authority to the user of the home device 100 to which the related information such as the access point IP address is not registered.

5 illustrates a process performed when the home-device 100 fails to perform UDP communication with the cloud server 400. FIG.

First, the home device 100, the router 200, and the cloud server 400 perform UDP hole punching in the router 200 through transmission of a UDP packet (step S21).

The home device 100 determines whether the UDP hole punching has been generated in the router 200 according to whether the UDP packet is received from the cloud server 400 (step S23).

If the UDP hole punching is not generated in the router 200 (step S23), the home device 100 transmits an HTTP Request signal for long polling to the cloud server 400 (step S25).

When a control transmission event is detected before a predetermined time (90 seconds in this embodiment) elapses after the HTTP Request [Long Polling] signal is received from the home device 100 (step S27) (step S31 ) Control signal to the home device 100 (step S33). When 90 seconds have elapsed, an HTTP Response [605-no control] signal is transmitted as a control end signal to the home device 100 100) (step S29).

Here, the cloud server 400 may delete the communication session after transmitting the control signal to the home device 100 or transmitting the control end signal.

On the other hand, the home device 100 receiving the HTTP Response [200-control request] signal from the cloud server 400 performs a control process corresponding to the control request signal (step S35).

When the home device 100 receives the HTTP Response [200-Control Request] signal or the HTTP Response [605-No Control] signal from the cloud server 400, the home device 100 generates a new HTTP Request [Long Polling] (400).

Accordingly, TCP communication is maintained between the home device 100 and the cloud server 400 for a predetermined time, and the home device 100 receives a control signal from the cloud server 400 through the TCP communication Can receive.

That is, when the UDP hole punching is generated in the router 200, the home device 100 can receive the control signal from the cloud server 400 through the UDP packet, and UDP hole punching is generated in the router 200 It is possible to keep the TCP channel continuously with the cloud server 400 and to receive the control signal through the TCP packet.

In this case, the cloud server 400 preferentially performs UDP communication with the home device 100 to reduce the load on the server. For the home device 100 that is not capable of UDP communication, TCP communication is performed, so that normal control can be performed on all the home devices 100.

Meanwhile, it goes without saying that the process of performing each of the above-described embodiments can be performed by a program or an application stored in a predetermined recording medium (for example, a computer-readable). Here, the recording medium includes an electronic recording medium such as a RAM (Random Access Memory), a magnetic recording medium such as a hard disk, and an optical recording medium such as a CD (Compact Disk).

At this time, the program stored in the recording medium may be executed on hardware such as a computer or a smart phone to perform each of the above embodiments. In particular, at least one of the functional blocks of the user terminal according to the present invention described above may be implemented by such a program or application.

The present invention is not limited to the above-described specific embodiments, and various modifications and changes may be made without departing from the gist of the present invention. It is to be understood that such variations and modifications are intended to be included in the scope of the appended claims.
