Abstract:
Disclosed is an apparatus for lighting control scheduling based on climate and weather information, which enables active lighting control, in which a local situation is reflected, by receiving various information related to climate and weather from a climate and weather information service provider (ISP) connected through the Internet in real time. The disclosed apparatus includes: a climate and weather information extracting unit which collects climate and weather information from a climate and weather ISP through a network, and which manages the collected climate and weather information; a lighting illumination control unit which generates information for controlling the illumination of lighting, based on information related to a weather condition and visibility among the climate and weather information obtained by the climate and weather information extracting unit; a lighting color/color temperature control unit which generates information for controlling the color and color temperature of the lighting, based on information related to temperature, humidity, and atmospheric pressure among the climate and weather information obtained by the climate and weather information extracting unit; a lighting on/off time adjusting unit which generates information for adjusting the on/off time of the lighting, based on the sunrise and sunset times of the sun among the climate and weather information obtained by the climate and weather information extracting unit; and a lighting control scheduler which controls the lighting according to a modified lighting control schedule by reflecting, in the predetermined lighting control schedule, information from the lighting illumination control unit, the lighting color/color temperature control unit, and the lighting on/off time adjusting unit.
Abstract:
In a illumination light communication system, a first illumination device receives data request information including an illumination light location ID of a second illumination device and a terminal ID of a terminal from the terminal having a visible light communication function, and acquires video session information on a video transmitted from the second illumination device by the terminal. Then, the first illumination device finds the video corresponding to the video ID, generates a related video frame on the basis of the video location included in the video session information, and transmits the video frame to the terminal using visible light communication, thereby supporting continuous transmission of video.
Abstract:
Provided is an apparatus for driving a LED lighting. The driving apparatus includes: a power supply unit for converting external AC power into voltage required to drive the LED lighting; a rechargeable battery charged from the power supply unit; and an MCS for receiving LED lighting control information to control the LED lighting and for receiving power from the power supply unit or the researchable battery. A first switch is connected between the AC power and the power supply unit, a second switch is connected between the researchable battery and the MCU, and a third switch is connected between the power supply unit and the MCU. Here, the MCU turns off the first and third switches and turns on the second switch if the LED lighting is turned off to receive power from the rechargeable battery.
Abstract:
Disclosed is a light network control method. The light network control method for operating a light network control device including a control device and a plurality of control gears comprises the following steps: the control device transfers the right of using a light network to a first gear among the control gears; the first gear checks if there is data to be transferred to the control device and transfers the data to the control device using the right of using the light network; and when the data transmission is completed, the first control gear transfers the right of using the light network to another control gear.
Abstract:
A method and an apparatus for reducing a packet forwarding delay in a router are provided to reduce delay or loss of a packet by having a local agent in a forwarding processor block and processing information between software blocks of a routing processor unit and a forwarding processor unit. A routing processor unit(110) checks a new routing entry to which a packet is to be forwarded, allocates a new connection identifier with respect to a next hop of the checked routing entry, and transfers information about the checked routing entry including the connection identifier. Forwarding processor units(120,130) allocate the new connection identifier through the information about the routing entry received from the routing processor unit, obtain a link layer address from the next hop and inform the routing processor unit, and forward the packet to the next hop according to the obtained link layer address.
Abstract:
An apparatus and a method for managing tunnel source information in a distributed IPv6 router are provided to improve the efficiency of address usage by making many tunnel interfaces have an identical tunnel source address using a tunnel interface index list. An apparatus for managing tunnel source information in a distributed IPv6 router comprises a management table, an operator command processor(21), an interface manager(22), and a forwarding server(23). The management table uses tunnel source addresses as indexes, and has tunnel indexes and tunnel interface identifiers as values. The operator command processor(21) parses a tunnel interface setup command inputted from an operator and creates tree-shaped tunnel interface information. The interface manager(22) delivers the tunnel interface information, received from the operator command processor(21), to the forwarding server(23) in the form of an event. The forwarding server(23) extracts a tunnel interface identifier and a tunnel source address from the event-type tunnel interface information and updates the management table.
