PROBLEM TO BE SOLVED: To provide a lighting control system and a control terminal device such that the lighting control system eliminates the need for manual re-control at the time of power recovery, etc.SOLUTION: A lighting control system 1 includes a central control device 11 and a plurality of control terminal units 13. Each control terminal unit 13 controls a lighting fixture 15 according to a command signal from the central control device 11. Each control terminal unit 13 includes a driving circuit 24, an FeRAM 22 which stores operation information corresponding to an operation signal to the lighting fixture 15, and a microcomputer 21. The microcomputer 21 once receiving a control command signal from the central control unit 11 controls an operation signal output from the driving circuit 24 according to the control command signal, writes operation information corresponding to the operation signal to the FeRAM 22, and reads the operation information out of the FeRAM 22 according to an inquiry signal from the central control device 11 and then transmits the information to the central control device 11. |
