For example, the controller 10 may implement a GUI screen classified according to the characteristics of the device to be controlled as shown in FIGS. 2A to 2C, and as shown in FIG. 3 corresponding to the GUI screen. It is possible to generate the control target device connection information for each GUI screen.

2A to 2C are exemplary views showing an example of a GUI screen implemented in a controller according to a preferred embodiment of the present invention, and FIG. 3 is a control target for each GUI screen including a controller according to a preferred embodiment of the present invention. An example diagram showing an example of device connection information.

That is, in FIG. 2A to FIG. 2C, the controller 10 divides the control target device into information electronic devices and home auto devices, and implements each as a separate GUI screen, and implements a mode control service as a separate screen.

Accordingly, the GUI screen (information appliance screen) of the information appliance shown in FIG. 2A provides a monitoring and control function for the refrigerator 21, the air conditioner 22, the washing machine 23, and the boiler 24, and FIG. 2B. The GUI screen (home auto screen) of the home auto apparatus shown in FIG. Provides a monitoring and control function for a plurality of lamps 31, electric curtains 32 and gas valve 33. In addition, the GUI screen (mode control screen) for the mode control service shown in FIG. 2C provides monitoring and control functions for weather, sleep and visitor recording.

In this way, communication with each controller 10 is performed. Here, the GUI communication between the master device 1 and the controller 10 based on the GUI common table may be performed using a data packet simplified to 'GUI screen number-controlled device number-function value'. For example, when the master device 1 detects that the state of the first lamp 31 that is the home auto device is changed from 'on' to 'off' and transmits a monitoring value for the change to the mobile phone 11. The master device 1 may send a data packet including '2-201-2002' to the cellular phone 11. In addition, the mobile phone 11, which is one of the controllers 10, includes a value of '1-104-1002' in the data packet when it is desired to 'off' the power of the boiler 24 according to the user's setting.

For example, when the controller 10 includes the control target device connection information for each GUI screen of FIG. 6, in order to turn on the power of the air conditioner 22, the controller 10 may use '0-102-1001' and '1-102'. The data format including all of -1001 'may be transmitted to the master device 1.

Therefore, when the master device 1 receives the control target device connection information for each GUI screen shown in FIG. 6 from an arbitrary controller device 10 and generates a GUI common table based thereon, In transmitting the data format according to the monitoring and control to the controller 10, both the function value included in the main GUI screen of the controller 10 and the function value of the GUI screen including the control target device are included. The formatted data format. For example, the master device 1 changes the boiler 24 on the home network from the 'off' state to the 'on' state with respect to the controller 10 including the control target device connection information for each GUI screen of FIG. 6. In the case of transmitting a data format for monitoring the data, the data format including both '0-104-1001' and '1-104-1001' may be transmitted.

Next, a GUI communication method of a home network system having such a configuration will be described in detail with reference to the accompanying drawings.

7 is a flowchart illustrating a home network GUI communication method according to a preferred embodiment of the present invention.

Referring to FIG. 7, in the home network system, the plurality of controllers 10 first generate connection information for control devices for each GUI based on GUI screens implemented by each user (S11), and initially connect with the master device 1. At the point of time, the generated control target device connection information for each GUI is transmitted to the master device 1 (S12). For example, any controller 10 may include a GUI screen illustrated in FIGS. 2A to 2C, and may include a GUI screen classified as 'GUI screen number-controlled device number-function value' as illustrated in FIG. 3. Connection information for each control device may be generated and transmitted to the master device 1.

Accordingly, the master device 1 generates a GUI common table based on the control target device connection information for each GUI screen transmitted for each controller device 10 (S13). For example, the master device 1 may generate a GUI common table as shown in FIG. 4.

From this, the master device 1 and each controller 10 perform GUI communication using a data packet including 'GUI screen number-controlled device number-function value' based on the generated GUI common table. (S14).
