Abstract:
The present invention relates to a method of processing a Digital Multiplex (DMX)-Visible Light Communication (VLC) address and a device using the method. In the method of processing a DMX-VLC address, a DMX-512 packet is received. It is determined whether the DMX-512 packet includes dimming data by using a start code of the DMX-512 packet. Lighting data is processed using an address recorded in a DMX-512 address field of a DMX-VLC address included in the DMX-512 packet if it is determined that the DMX-512 packet includes the dimming data. Non-lighting data is processed using an address recorded in a DMX-VLC extended address field of the DMX-VLC address if it is determined that the DMX-512 packet does not include dimming data.
Abstract:
An apparatus and a method for measuring a position of a light are disclosed. The apparatus for measuring a position of a light includes: an inputting unit configured to receive position information on a building and a floor in which a user is positioned; a position coordinate calculating unit configured to measure distances between a position of the user and wall surfaces in the building in each direction and calculate a position coordinate of the user based on the distances in each direction; a position determining unit configured to apply the position coordinate to a plan view corresponding to the position information to determine an initial position of the user; and a position information combining unit configured to receive a light identifier depending on movement of the user and store position information of the light corresponding to the light identifier.
Abstract:
Disclosed herein is a visible light communication method and device using a DMX-512 network. In the visible light communication method, dimming data packets are received. Visible Light Communication (VLC) data packets are generated. The dimming data packets and the VLC data packets are scheduled so that one or more of the VLC data packets are transmitted to Light Emitting Diode (LED) lighting devices connected over a Digital Multiplex (DMX)-512 network between transmission times of the dimming data packets.
Abstract:
A method and apparatus for processing a real-time data stream. The method for processing a real-time data stream based on a rule includes selecting a rule corresponding to a current factory state with reference to a rule engine in which factory states are mapped to rules corresponding thereto, analyzing a real-time data stream to be used to control a factory resource, and, when a result of the analysis satisfies a condition defined in the rule, controlling a factory resource so as to take an action corresponding to the defined condition. According to the method, the real-time data streams collected in a factory or flowing from outside the factory are processed to be suitable for the environment in the factory, whereby the operating rate and productivity of the factory may be improved.
Abstract:
Disclosed herein are an apparatus and method for controlling a lighting network. The apparatus for controlling lighting network includes a control device and a plurality of control gears. The control device generates and transfers commands to control lighting. The plurality of control gears receives the commands from the control device and control lighting. The control device assigns a right to use a lighting network to the control gears, and the control gears send information about a change in a lighting state or error details to the control device using the right to use a lighting network.
Abstract:
Disclosed herein are a Zigbee lighting control apparatus and method. The Zigbee lighting control method includes checking whether a Zigbee switch to which a Zigbee lighting control apparatus is applied is in a reset state, performing a broadcast-based link connection a number of times identical to a number of currently installed Zigbee lighting devices if the Zigbee switch is in the reset state, performing a broadcast-based link connection a number of times identical to a preset number of Zigbee lighting devices if it is checked that the Zigbee switch is not in the reset state, performing a unicast-based link connection on remaining Zigbee lighting devices that are not connected to a link, among Zigbee lighting devices within a preset range upon performing the broadcast-based link connection, and controlling Zigbee lighting devices that have been connected via the broadcast-based link connection or the unicast-based link connection.
Abstract:
A lighting control device and method are disclosed herein. The lighting control device includes a control unit and a control request unit. The control unit sets up a virtual multiple lighting control unit corresponding to a lighting control command received from a lighting management device. The control request unit selects a wireless light fixture corresponding to a light fixture ID included in the lighting control command, and makes a lighting control request to the selected wireless light fixture. The control unit transfers a response to the lighting control request to the lighting management device, and thus allows a corresponding lighting switch to control the wireless light fixture.
Abstract:
An apparatus and method for controlling lighting are disclosed. The apparatus includes a reception unit, a determination unit, a state determination unit, and a lighting control command transmission unit. The reception unit receives an event message from a light sensor. The determination unit determines whether the event message is an event message attributable to a change in luminance or an event message related to a DALI system. If it is determined that the event message is the event message attributable to a change in the luminance, the state determination unit determines the luminance change state of a lit space using the event message attributable to a change in the luminance. The lighting control command transmission unit sends a lighting control command corresponding to the luminance change state using a control group address.

The intelligent lighting control apparatus includes a multi-sensor unit including multiple sensors, the multi-sensor unit sensing motion of a person or an object within a set sensing area using at least one of the multiple sensors. A lighting control unit controls an operation of a lighting unit based on frequency data corresponding to results of sensing by the multi-sensor unit and a class of lighting type corresponding to the frequency data.
Abstract:
The present invention relates to a motion sensor and method of operating the motion sensor, which can adjust the range of a detection area. For this, the motion sensor according to the present invention includes a detection unit for outputting a variation signal corresponding to motion. A threshold level setting unit variably sets at least one changeable threshold level. A comparison unit detects the motion by performing a comparison operation based on the changeable threshold level and the variation signal at threshold sensitivity corresponding to the changeable threshold level.
