| Abstract;Technical outline and practical system of SS modulation power line carrier system are described. This system has features including reduced external noise, long-haul transmission, receiving reduced effects of interference wave, automatic realization of redundance, reduced effects to outside. Practical application can be observed in works for electric power, petrochemicals, semiconductor. Application examples and instrument composition of gas sensing system are outlined. It has problems at moment in limited connected slave station based on increased voltage drop resulted from common use of signal line and electric power line. |
