To provide a light control monitoring system by power line carrier communication that performs modulation, signal generation, and demodulation in consideration of signal attenuation, noise influence, and low power consumption.SOLUTION: A lighting control monitoring device 1 incudes a timing detection unit that detects a specific timing from the power supply waveform in a master station 6 and a terminal Ri. In a plurality of terminals Ri, a different spreading code data is held for each terminal, and in the master station, the spreading code data held by the terminal Ri is held. By this means, in the terminal, demodulation of a reception signal and modulation of a transmission signal are performed by using the spreading code data different depending on each terminal, and in the master station, the demodulation of the reception signal and the modulation of the reception signal are performed by the spreading code data held by each terminal Ri.SELECTED DRAWING: Figure 1 【課題】信号の減衰やノイズの影響、低消費電力を考慮して変調・信号発生・復調を行う電力線搬送通信による灯火監視制御システムを提供する。【解決手段】灯火制御監視装置１は、親局６と端末Ｒｉにおいて、電源波形から特定のタイミングを検出するタイミング検出部を備える。複数の端末Ｒｉにおいて、端末ごとに異なる拡散符号データを保持するとともに、親局において、各端末Ｒｉが保持する拡散符号データを保持する。これにより、端末において、端末ごとに異なる拡散符号データで、受信信号の復調及び送信信号の変調を行うとともに、親局では各端末Ｒｉが保持する拡散符号データで、受信信号の復調及び送信信号の変調を行う。【選択図】図１
