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

1 is a diagram illustrating a network configuration of a wireless home networking system according to the present invention.

As shown, the wireless home networking system includes a plurality of wireless local node modules 10, 30, 50, and 70, a wireless local coordinator module 100, a gateway module 200, and a home networking server 300.

The wireless short-range node module 10 is mounted on each indoor electronic device, such as a television, a refrigerator, and an air conditioner, to directly control a circuit of the electronic device.

The wireless local area coordinator module 100 performs local area communication according to a plurality of wireless local node modules 10, 30, 50, and 70 and a local area communication standard (eg, the IEEE 802.15.4 standard in the case of Zigbee). The wireless local node control module 120 for wirelessly controlling the wireless local node module 10, the wireless near-field control matching module 140 for controlling and matching the wireless local area modules, and the gateway module 200 based on the UPnP protocol. An operating module (OS) 180 including programs for controlling and adjusting the overall operation of the device control module 160 and the wireless local area coordinator module 100 to perform communication and control the device.

Here, the short-range communication transmitted and received between the wireless local node module 10 and the wireless local coordinator module 100 is Bluetooth (V1.2 / IEEE 802.15.1), Zigbee (IEEE 802.15.4), One of RFID (Radio Frequency Identification).

In addition, the wireless local coordinator module 100 communicates with the home networking server 300 through the gateway module 200 provided in the home.

The home networking server 300 is connected to the mobile communication network 500 and the Internet 400, and a user connects using a mobile communication terminal 520 or a personal computer 420 to query the state information of the electronic device. Provide home networking services such as state control.

2 is a flowchart illustrating an initial configuration process of a wireless short range module according to the present invention.

First, the wireless local coordinator module 100 transmits a signal for restarting to the wireless local node module 10 to configure the wireless communication path according to the wireless local node module 10 and the IEEE 802.15.4 standard (S101). ).

Subsequently, when the wireless local area coordinator module 100 receives a response message transmitted from the wireless local area node module 10 (S103), the wireless local area node module receives information about the number of wireless local node modules to communicate with the wireless local area coordinator module 100. It transmits to the module 10, and receives a response (S105, S107).

The wireless local coordinator module 100 transmits initial setup information to the wireless local node module 10 and receives a response thereto (S109 and S111). The initial configuration information may include RF channel information, RF power information, wakeup interval information of the wireless local node module, type information and number information of devices controlled by the wireless local node module, and the like. do.

Subsequently, when the wireless local node module 10 normally completes the initial setting, the wireless local node module 10 transmits startup information (UP information) of the wireless local node module to the wireless local coordinator module 100 (S113).

After step S113, as the wireless local coordinator module 100 receives the startup information of the wireless local node module transmitted from the wireless local node module 10, the wireless local coordinator module 100 and the wireless local node module 10 between the wireless local node module 10. The communication path is configured.

3 is a flowchart illustrating a method of obtaining electronic device information according to the present invention, which is a process after the initial setting process described in FIG. 2 is completed.

First, when the state of the wireless local node module 10 enters the startup (UP) mode, the wireless local coordinator module 100 performs a process of a UPnP (Universal Play & Plug) device corresponding to the wireless local node module 10. It generates (S201).

Thereafter, the gateway module 200 generates a UPnP control process at start-up (S203). When a preset time arrives, the gateway module 200 checks whether a UPnP device is searched (not shown).

As the wireless local coordinator module 100 generates a UPnP device process, when a UPnP device is found, the gateway module 200 requests a description document of the device from the wireless local coordinator module 100 (S205). In response thereto, a guide document of the corresponding device is received (S207).

Thereafter, the wireless local coordinator module 100 requests a service description document of a device from the wireless local coordinator module 100 (S209), and receives a service guide document of the corresponding device in response thereto (S211). ).

The guide document of the device and the service guide document of the device include specification information of electronic devices installed in the wireless home network and control information of the electronic devices.
