Emission control system using barcode information
First Claim
1. A master device controlling a plurality of slave devices, comprising:
- a communication unit; and
an emission control unit configured to broadcast a emission control signal corresponding to emission position information indicating specific positions at which the plurality of slave devices emit lights, through the communication unit,whereinthe emission position information includes information previously set to group the plurality of slave devices, andwhen emission position information of a first plurality of slave devices among the plurality of slave devices are set previously to group as A0 group and emission position information of a second plurality of slave devices among the plurality of slave devices are set previously to group as B0 group, the emission control unit broadcasts the emission control signal including a first emission control signal corresponding to the emission position information of the A0 group and a second emission control signal corresponding to the emission position information of the B0 group.

Abstract
Disclosed are an emission control system and mater and slave devices for the emission control system. The master device controlling one or more slave devices includes a communication unit, an electrical code identification unit identifying electrical code information previously output, an information check unit checking emission position information previously set in accordance with the identified electrical code information and indicating specific positions at which the slave devices emit a light, an information providing unit providing the checked emission position information to a first slave device corresponding to one of the slave devices, and an emission control unit broadcasting the emission control signal corresponding to the emission position information through the communication unit.

6. A slave device controlled by a master device, comprising:
-
a communication unit; an emission unit configured to include at least one light source device; an information receiving unit configured to receive emission position information corresponding to previously-set electrical code information from the master device; and an emission control unit selectively configured to receive an emission control signal corresponding to the emission position information at a position corresponding to the emission position information among emission control signals broadcasted by the master device and control the emission unit on the basis of the received emission control signal, wherein the emission position information includes information previously set to group a plurality of slave devices, and when the emission position information of the slave device includes information previously set to group the slave device as A0 group, the emission control unit selectively receives a first emission control signal corresponding to the emission position information of the A0 group among the emission control signals and controls the emission unit based on the first emission control signal. - View Dependent Claims (7, 8, 9, 10, 11)

12. A master device controlling a plurality of slave devices through at least one sub-master device, comprising:
-
a communication unit; and an emission control unit configured to provide an emission control signal to a first sub-master device through the communication unit so as to selectively control emission of a first slave device by controlling a radio wave intensity of the first sub-master device located at a position spaced apart from a first emission position of the first slave device among the plurality of slave devices, wherein the emission control signal includes a first emission pattern value to allow a first plurality of slave devices located in a first control radius set in accordance with the radio wave intensity of the first sub-master device to control the same emission control signal. - View Dependent Claims (13, 14, 15, 16, 17, 18)
