MONITOR CONTROL SYSTEM USING POWER LINE CARRIER

摘要

PROBLEM TO BE SOLVED: To assure a transmission of high quality by reducing an influence of a noise generated from a power generator. SOLUTION: A monitor control system using a power line carrier comprises inductance elements L11 and L12 which extend at an apparatus distance from the power generator 4 on the way of a power line 5 led from the power generator 4, an LC resonance circuit for resonating at a frequency used for a power line carrier between output ends of the elements, and a filter unit for electrically completely isolating a power source side and a lamping unit side (a master station 8 and respective terminals 9).
