<P>PROBLEM TO BE SOLVED: To provide a load control system which provides a required SN ratio on a communication signal transmitted via a DC supply line even when a control request to a plurality of DC loads is generated. <P>SOLUTION: In a load control system, a terminal device 4 comprises: a terminal side communication unit 41 which transmits/receives a communication signal using a DC supply line 2 as a transmission channel; and a processing unit 42 which provides a control request to DC loads 3 using the communication signal. Each DC load 3 comprises: a loading side communication unit 31 which transmits/receives the communication signal using the DC supply line 2 as a transmission channel; and a control unit 32 which controls operational state in response to the control request from the terminal device 4. Each DC load 3 further includes an adjustment unit 7 which shifts control timings DC load 3 by DC load 3 when the control unit 32 controls the operation state in response to the control request from the terminal device 4. The adjustment unit 7 issues an instruction to control the operation state to the control unit 32 in response to the control request at a time when a queuing time unique to each DC load 3 elapses after the loading side communication unit 31 receives the communication signal including the control request. <P>COPYRIGHT: (C)2013,JPO&INPIT |
