As described above, the master device of the present embodiment may be a gateway device or an LED device having a communication module capable of transmitting and receiving data with the control terminal.

However, for convenience of explanation, the case where the master device is composed of a gateway will be described below as an example.

4, the master device 100 includes an Ethernet transmitting unit 131 and an Ethernet receiving unit 132 for transmitting / receiving data remotely to / from the control terminal 10, and a Zigbee communication unit A memory unit 140 for storing data transmitted and received by Ethernet or Zigbee communication, and a master control unit 110. The Zigbee transmitting unit 121 and the Zigbee receiving unit 122 are connected to the Zigbee transmitting unit 121 and the Zigbee receiving unit 122, respectively. Here, the Ethernet transmission unit and the Ethernet reception unit may be the first communication module of the master device, and the zigbee transmission unit and the reception unit may be the second communication module of the master device.

The Ethernet transmitting unit 131 and the Ethernet receiving unit 132 are for transmitting and receiving data to and from the control terminal 10. The Ethernet receiving unit 132 receives a control signal transmitted from the control terminal 10 and transmits the control signal to the master control unit 110, .

5 is a block diagram showing a configuration of a lighting apparatus according to the present embodiment.

5, the lighting apparatus 200 includes a ZigBee transmission unit and ZigBee reception units 221 and 222 for communicating with the master device 100 acting as a gateway, a lighting control unit (not shown) for controlling the operation of the LED devices A memory unit 240 capable of storing data to be transmitted and received and LED devices 250 having on / off or brightness controlled according to the control of the illumination controller 210.

Refer to the flow charts of Figs. 6 and 7 for the communication between the master device and the lighting device and the updating of the command by the communication.

6 is a flowchart illustrating a lighting control method according to the first embodiment of the present invention.

6 and 7, the controller may be the control terminal described above, or may be a remote controller for lighting control, and the slave device may be understood as a lighting device to be controlled.

The controller of the present embodiment, that is, the control terminal, can be driven by an application provided by the manufacturer of the lighting apparatus, and the fact that such an application is activated means that it is possible to update the control command of the lighting apparatus through updating of the application. In order to transmit a command included in a control signal transmitted from the control terminal to the illumination device, the master device 100 may transmit the command to the master device 100. [ The list of commands of the host computer 100 must also be updated.

To this end, in this embodiment, the control terminal may request the master device to update the command for lighting device control (S101).

A data format for allowing the master device to confirm whether data transmitted from the control terminal indicates a command update request is illustrated in FIG.

The data format shown in FIG. 8 is an example of a data structure that can be transmitted between the control terminal and the master device, and is composed of a header and a payload as in a general data format.

However, according to the present embodiment, a header may be configured to request a command update, and one bit may be allocated as management or control classification data. For example, in the master device, when the classification field is 1 in the header of the received control signal, it is judged as a command update request, and when the classification field is 0, it can be judged as data for controlling the general lighting device.

Thus, it is possible to promptly confirm whether the signal for controlling the lighting apparatus or the signal for updating the control command of the lighting apparatus is included in the header area of the control signal.

In addition, the field values included in the payload area can be read out when the corresponding control signal controls the operation of the lighting device. For example, the value type indicates whether the lighting device is on and off, the dimming level, It becomes the code for sorting. And, the max / min value field can be a value that defines the maximum minimum value that can be used in the lower device of the value defined in value type. And, the reserve field can be a value for general data extension.

Through this configuration of the data format, the master device can promptly check whether or not the command update request is requested from the control signal transmitted from the control terminal.

Meanwhile, when receiving a command update request signal from the control terminal, the master device determines that the network-connected illumination device is newly added or updated, and requests the command list from the connected lighting devices (S102).

The slave devices requested to transfer the command list from the master device transmit the command list stored in the memory to the master device (S103).

Next, the master device compares the command list transmitted from the slave devices with the pre-stored command list, and stores the updated information in the memory unit (S104). For example, when there is new unique ID information, the new slave device is registered as a new slave device. If any one of the slave devices is changed or added, the slave device is identified and the updated command is stored.

Then, the master device transfers the updated information of the slave device to the control terminal (S105), and the control terminal updates the control GUI or updates the command list with reference to the command list transmitted from the master device (S106) . For example, a slave device connected to the master device on the display unit of the control terminal, i.e., a newly added item of the lighting device may be displayed, or an instruction to control the operation of the lighting devices may additionally be displayed.

Through this method, the update of the command list by the master device can be easily performed through the update of the application driven by the control terminal.

7 is a flowchart illustrating a lighting control method according to the second embodiment of the present invention.

7 is a diagram showing an example in which, even when a control signal requesting a command list update related to the control of the illuminating device is not received from the control terminal side in comparison with the first embodiment in Fig. 6, It is possible to update the command list stored in the master device and the UI of the control terminal.

First, the master device of the embodiment may transmit a message requesting to transmit status information to the slave device every predetermined period (S201). For example, the master device may request to transmit the unique ID information and the command list to the network-connected illumination devices every predetermined period.

In response to this, the slave device transmits its unique ID information and version information of the command list related to the operation to the master device (S202). Here, the unique ID information transmitted by the slave device and the command version information may be status information of the lighting apparatus.

The master device compares the received status information of the slave device with the stored status information, and determines the slave device that requires updating of the command list (S203).

Then, the master device requests the slave device to update the command list (S204). In response thereto, the slave device transmits its own ID information and the command list to the master device (S205 ).

Then, the master device identifies the illumination device from the transmitted unique ID information, and stores the list of commands transferred for each illumination device (S206)

In this manner, when the master device updates the command list by checking the status information of the periodic slave devices, the master terminal can transmit a message to the control terminal requesting to update the application of the control terminal (S207). At this time, the signal transmitted to the control terminal may be transmitted together with the application update request message of the control terminal together with the information about the slave device that has been updated.

Through this process, the control terminal can update the GUI or the menu indicating the control command of the lighting device to be controlled. It is also possible for the control terminal to control the additional connected lighting device or to control the additional operation of the lighting device by storing a list of commands included in the delivered update information.
