<P>PROBLEM TO BE SOLVED: To provide a lighting control system capable of improving system responsiveness. <P>SOLUTION: In a lighting control system 1 of an embodiment, a central control unit 2 controls a plurality of control terminals S by communicating with a plurality of control terminals S via a transmission line 3. The central control unit 2 transmits a transmission frame 30 to the plurality of control terminals S via the transmission line 3. The transmission frame 30 includes a control transmission part 31 having at least an addresses of the control terminal S and a control data part 30e including control data, and a monitor response part 33 for a monitor response following the control transmission part 31. Among the plurality of control terminals S, the control terminal S corresponding to an address in the transmission frame 30 adds a response signal indicating a control state of a lighting apparatus to the monitor response part 33 in the transmission frame 30 and then transmits the response signal to the central processing unit 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
