The home network system 1 is for efficiently managing and controlling an appliance that performs operations and operations preset by a user or a program, and includes a master device 10 and an appliance 20 .

The master device 10 and the appliance 20 are connected through a wired/wireless network (LAN, RF Network, etc.) to perform data communication with each other.

The master device 10 is installed in a structure (ceiling, wall, etc.) in the home and performs a function of relaying between people and appliances (ventilator, lighting device, heating device, etc.). In the present invention, for convenience of description, the master device 10 has been described as an example of one, but a plurality of master devices 10 may be installed, for example, one for each room or two for the living room. More than one can be installed.

The master device 10 is connected to the appliance 20 through a wired/wireless network, and includes a transceiver 11 , a storage unit 12 , and a control unit 13 .

The transceiver 11 is in charge of the communication function (RF communication, etc.) of the master device 10 and transmits and receives data. The transceiver 11 transmits the control signal 30 to the appliance 20 through a wired/wireless network.

In this case, the control signal 30 includes a header field 31 , a data field 32 , and a trailer field 33 . The header field 31 may include an identification ID number of the appliance 20 . Specifically, the appliance 20 communicates with the master device 10 through a wired/wireless network, and at this time, each appliance 20 is registered with the master device 10 and has a unique identification ID number (eg, Ox00, Ox01, etc.) ), and is identified using it.

The storage unit 12 is responsible for storing data, and control data 12a capable of driving and controlling the appliance 20 is stored. The storage unit 12 may store the pattern data 12b in which the control data 12a is grouped for each pattern. Here, the control data 12a is data for operating and controlling the appliance, and may include, for example, driving, driving stop, driving speed, driving time, self-diagnosis, and the like.

The control unit 13 is in charge of overall control of the master device 10 , and includes a pattern generating unit 13a and a pattern matching unit 13b.

The pattern generating unit 13a sets all control situations that may occur in the appliance 20, classifies data required for the control situation, and defines or defines it as one pattern variable.

The pattern generator 13a includes control data 12a (start/stop of supply air, start/stop of exhaust fan, high/medium air volume) corresponding to preset environmental variables (temperature, humidity, carbon dioxide concentration, fine dust concentration, etc.). /about), operating time, etc.) are searched in the storage unit 12 to generate the pattern data 12b.

For example, the pattern generator 13a may generate the pattern data 12b composed of only the control data 12a corresponding to the environment variable having the largest change amount for a preset time. That is, if the variation in the concentration of ideal carbon in the room is high, the pattern generating unit 13a operates the exhaust fan and the supply fan, and sets the operating time (for example, 6 hours) to the maximum while increasing the intensity of the air volume. can

As shown in FIG. 5 , the pattern matching unit 13b matches the pattern data 12b generated above with preset pattern variables (pattern A, pattern B, etc.). The pattern matching unit 13b may match the control data 12a transmitted to the master device 10 by determining that the appliance 20 corresponds to the current environment variable to the new pattern variable.

In this way, it is possible to define the combinations of control data patterned according to the control situation as a pattern from A to Z. Here, the pattern variable is preferably arranged in the header field 31 of the control signal 30 , and the pattern data is arranged in the data field 32 .

In this way, by patterning and using only necessary data, it is possible to control the necessary operation of the appliance 20 while reducing the size of data transmitted from the master device 10, and consequently improve the communication speed as well as the communication error rate. be able to do

The appliance 20 is a device installed in the home to perform specific calculations and operations, and in detail, may include a ventilation device, a lighting fixture, a door lock, an air conditioner, a video phone, a vacuum cleaner, a microwave oven, an electric rice cooker, and the like.

Appliances 20 include a storage unit 17 , a transceiver unit 15 , and a control unit 16 .

The transceiver 15 is in charge of the communication function of the appliance 20 , and may provide the control signal 30 received from the outside to the control unit 16 .

The storage unit 17 is responsible for storing data, and control data 18a capable of driving and controlling the appliance 20 is stored. The storage unit 17 may store the pattern data 18b in which the control data 18a is grouped for each pattern. In this case, the control data 18a and the pattern data 18b may be stored by themselves or received from the master device 10 and stored.

The control unit 16 performs overall driving and control functions of the appliance 20, and includes a pattern analysis unit 16a and a driving unit 16b. In this case, the control unit 16 may be embedded in a chip of the appliance 20 itself or configured as a removable memory such as USB.

The pattern analysis unit 16a may determine whether the pattern data 12b received from the outside corresponds to the current environment variable. The pattern analysis unit 16a may re-request the control signal 30 to the master device 10 if the pattern data 12b does not correspond to the current environment variable.

Specifically. The pattern analysis unit 16a sends a control signal ( 30) can be requested again.

At this time, the appliance 20 may also transmit the control data 12a determined to correspond to the current environment variable to the master device 10 together with the appliance 20 . In particular, the appliance 20 may transmit the control data 12a generated by determining the current concentration of carbon dioxide and fine dust to the master device 10 .

Here, the current environmental variables (temperature, humidity, carbon dioxide concentration, fine dust concentration, etc.) can be determined using sensors installed inside and outside the home or information collected through wired/wireless networks such as the Internet.

Hereinafter, a home network method according to another embodiment of the present invention will be described with reference to FIG. 3 .

First, pattern data 12b consisting only of control data 12a corresponding to preset environmental variables (temperature, humidity, carbon dioxide concentration, fine cotton concentration, etc.) from a plurality of control data 12a stored in the master device 10 is generated (S10).

Here, the control data 12a is data for operating and controlling the appliance, and may include, for example, driving, driving stop, driving speed, driving time, self-diagnosis, and the like.

Next, the pattern data 12b generated in step S10 is matched with a preset pattern variable (S20). Specifically, as shown in FIG. 5, the operation mode (1), the air volume (2), the air supply damper (3), the air supply fan (6), and the fine dust (indoor) concentration (9) are matched to the pattern A. In this case, the pattern data 12b and the pattern variable may be matched with each other by a matching code (eg, A12369).

to the next. The master device 10 transmits the control signal 30 to the appliance 20 (S30)

Next, the appliance 20 determines whether the pattern data 12b included in the control signal 30 corresponds to the current environment variable (S40).

Next, when the pattern data 12b corresponds to the current environment variable, the appliance 20 uses the control command of the control data 12a included in the received control signal 30 by itself (the appliance 20). drive and control (S50).

On the other hand, when the pattern data 12b does not correspond to the current environment variable, the control signal 30 is requested again from the master device 10 (S60).

Here, the appliance 20 may also transmit the control data 12a determined to correspond to the current environment variable to the master device 10 together with the appliance 20 . In particular, the appliance 20 may transmit the control data 12a generated by determining the current fine dust concentration, air volume, etc. to the master device 10 .

Meanwhile, the master device 10 may match the control data 12a transmitted by the appliance 20 by determining that it corresponds to the current environment variable to a new pattern variable (eg, pattern E).

As a result, in the home network system and method according to the present invention, the master device not only improves the communication speed but also improves the communication error rate by matching the pattern data generated by configuring only the control data corresponding to the preset environmental variables with the preset pattern variables. can be improved.
