We developed a monitoring system which enables monitor of plant equipment at low cost without construction of new signal cables by transmitting the CCD camera image and vibration data using established signal cables. This system uses a signal cable which detects opening and closing of a motor operated valve (MOV) and superimposes the CCD camera image and the signal of microphone or accelerometer on the voltage signal of the signal cable of MOV by modulating these monitoring signals. The monitoring signal is separated with the voltage signal, and is demodulated and is displayed as the image, sound and vibration data. It was clarified that this system can transmit the monitoring signal without influencing detection of opening and closing of MOV.
