FIG. 11 is a signal flow diagram illustrating a process and an operation procedure of a smart home grid using a network storage device according to an embodiment of the present invention. Referring to FIG.

Referring to FIG. 11, when the network storage device 700 finishes booting, it automatically transmits a smart home grid creation request message to the home management server 710 (S800). At this time, the generation request message can include MAC (Media Access Control) information and serial information of a home gateway to participate in the smart home grid. That is, the user of the network storage device 700 receives the MAC information and the serial information of the home gateways of other family members in advance, and can utilize the MAC information and the serial information as the base information in the construction of the smart home grid.

The home gateways 720a and 720b collect information about the home tactical devices 730a to 730f installed in the home through the ZigBee / PLC interface after establishing connection (TCP connection) with a home gateway that is already known automatically after booting, And generates information on the home tag apparatus. In addition, the home gateways 720a and 720b connect to the home management server 710 and transmit a smart home grid participation request message (S805 and S810). At this time, the participation request message includes MAC information of the home gateways 720a and 720b, serial information, and the like.

When the home management server 710 receives the smart home grid creation request message from the network storage device 700, the home management server 710 generates a smart home grid network ID, searches member information of the smart home grid connected in advance, Generates a list of IP addresses, MAC information, and serial information of the home gateways to be participated, and transmits the list to the network storage 700 (S815).

The home management server 710 transmits a response message including the IP address of the network storage device 700 managing the smart home grid network to the home gateways 720a and 720b (S820 and S825).

The home gateways 720a and 720b connect to the network storage 700 using the received IP address, and then request authentication to the network storage 700 using their MAC information and serial information (S830, S840 ). Upon receiving the authentication request from the home gateway, the network storage 700 authenticates the home gateways 720a and 720b using the IP address, MAC information, and serial information transmitted from the home management server 710, And transmits a response message (S835, S845).

The home gateway transmits information about the family home tag device to the storage 700 of the network after authentication (S850, S855). After transmitting the information on the home tag apparatus, the home gateway waits for a control command of the network control apparatus 700. [

The network storage device 700 authenticates the home gateways 720a and 720b, receives information on the home tag devices connected to the home gateways 720a and 720b, and stores and updates related data in the database. Then, information of the database generated at this time is used for state information or control of a specific home tag device.

The home tactical devices 730a to 730f request connection or control (for example, connection / disconnection of power) to the home gateways 720a and 720b through the ZigBee / PLC interface and transmit the power consumption amount, the CO2 detection amount information, , Fire detection information, and the like.

When the home smart grid is configured in this way, the family member establishes a connection using the domain address of the network storage 700 through his / her terminal, and uses the user ID and the password to access the network storage 700, ≪ / RTI > Using the displayed user interface, statistical information such as time, day, and month of the entire smart home grid network can be monitored, and statistical information such as time, day, and month for each household can be monitored.

In addition, it is possible to perform real-time power consumption and status information monitoring or desired control of various information communication devices or home appliances connected through a home-tact device connected to a smart home grid network. Members of the family members who are rich in IT experience can perform the environment setting of the network storage device 700 and the home management server 710 necessary for constructing the smart home grid network.

By this process, a smart home grid can be constructed, power consumption can be measured, and desired control can be performed. In addition, one of the wealth of IT-savvy family members can configure and manage a smart home grid through a single network storage device, so unlike a typical Smart Grid service, a user without IT experience can simply connect the home gateway to the router in the home. After the home tag device is connected to the power line of each information communication device and the home appliance, the smart home grid service can be easily utilized by using an interface such as a web or a smart phone as if surfing the Internet.

Meanwhile, one or more subnets may be created in the home network because one or more internet gateways may exist in the home network as the complexity of the home network increases. In this case, depending on the subnet to which the network storage device is connected and the subnet to which the user's smart portable device or PC is connected, it may be very difficult to find and connect the network storage device installed in the same home network. Therefore, the necessity of network storage device discovery and connection automatically connected to the home network regardless of the location of the user on the network becomes a very important evaluation factor in convenience of use of the network storage device.

FIG. 12 is a diagram for explaining a discovery and connection procedure of a network storage device connected to a home network.

Referring to FIG. 12, when the network storage devices 900a and 900b are booted, a network plug and play (NPnP) service is automatically started. At this time, the NPnP service uses the traceroute utility on a well-known network server (e.g., www.google.com , www.naver.com ) to collect information of the connected home network, And collects information on how many Internet gateways are installed on the route to the Internet. In response to the traceroute request, if the address of the router is private IP, the router on the path determines the network level of the network storage device according to the number of the Internet gateways. For example, as shown in FIG. 12, when three Internet gateways 935, 940, and 945 are found, level 3 is obtained.

The NPnP service transmits the model name, MAC address, IP address, and network level value of the network storage devices 900a and 900b to the NPnP server 910 through the NPnP protocol.

The NPnP server 910 stores the registration information of the NPnP service received through the NPnP protocol and the source address of the NPnP packet in the network storage devices 900a and 900b in the NPnP database.

The structure of the NPnP database consists of an NPnP service table and an NPnP client table. Here, the NPnP service table is composed of <model name, MAC address, interface IP address of NPnP service, network IP address of NPnP service, and network level information>. The NPnP client table consists of <OS type, user ID, user password, NPnP client interface IP address, NPnP client network address, network level information, NPnP service MAC address list>.

The execution of the related functions in the NPnP client (960) can be installed through the user registration web page of the already known NPnP server (910) by the NPnP user through the installation CD which is automatically installed on the NPnP user's smart portable device or PC . When the related function is executed in the NPnP client 960, a traceroute is performed to collect network information automatically connected to the NPnP service to collect information such as the network level information and the interface IP address. The NPnP client 960 requests the user to input a User ID and a password for user authentication.

After completion of user input, user authentication is attempted with the NPnP server 910 set in advance. If the user authentication fails, the user registration page is automatically displayed on the screen and the user is prompted to input appropriate data. At this time, the input information includes a user ID to be registered, a password, a user authentication method (mobile authentication or OTP), and a MAC address or list of network storage devices to be registered. Upon successful user authentication or successful user registration, the NPnP client 960 transmits the User ID, the interface IP address, the network IP address, and the network level information through the NPnP protocol, and the NPnP service list 910 accessible from the NPnP server 910 Information is provided.

The NPnP server 910 searches the NPnP database to configure the NPnP service list using the NPnP database in response to the NPnP service list request from the NPnP client 960. [ Searches the NPnP client table of the NPnP database using the user ID provided by the NPnP client 950, finds the MAC address list of the NPnP service, and retrieves each NPnP service information from the NPnP service table.

Use the retrieved NPnP service information to check whether the NPnP service is currently accessible (Online or Offline). In the online NPnP service list, the network IP address provided by the NPnP client is compared with the network IP address registered by the NPnP service for each NPnP service, and it is determined whether or not the network IP address exists in the same network.

If they exist in the same network, the network level information is compared with each other to determine the interconnect type. At this time, if the network level of the NPnP client 960 is larger than the network level of the NPnP service, it is determined that the direct connection is possible, and the access is confirmed by using the "ping" tool program. In the opposite case, it is judged that connection via NPnP server is possible. When the connection type is determined, the NPnP server 910 provides the NPnP client 960 with a list of connectable NPnP services and connection type information.

When connecting via the NPnP server 910, the NPnP server 910 requests the NPnP client 960 to start the tunnel creation procedure to the corresponding NPnP service before providing the NPnP service list. In the NPnP service, the tunnel generation procedure can be generated by various methods such as UDP / HTTPS / SSH / IPSEC.

The NPnP client 960 receives model information and connection type information of the NPnP service accessible from the NPnP server 910, and displays the NPnP service list to the user. If the NPnP client 960 can directly connect, it tries to connect to the corresponding NPnP service using the network IP address of the NPnP service and the IP address of the NPnP server when connecting via the server.

When the NPnP client 960 tries to connect via the server, the NPnP client 960 starts the tunnel creation procedure with the NPnP server 910 similar to the NPnP service, and after the tunnel creation is completed, Binds the registered port number to hook up a data packet generated by a separate port number. The data packet acquired due to packet interception of a specific application destined for the NPnP service is routed to be forwarded to the NPnP server 910 and the created tunnel.

This process enables automatic discovery and connection of the network storage device connected to the home network regardless of the location of the user in the network. Enabling zero configuration for an Internet gateway in a home network that is required for a user to access a home network storage device.

Meanwhile, the present invention can be implemented as a code that can be read by a processor in a recording medium readable by the processor. The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also a carrier wave such as transmission over the Internet. In addition, the processor readable recording medium may be distributed over networked computer systems so that code readable by the processor in a distributed manner can be stored and executed.

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, but, on the contrary, It should be understood that various modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
