PURPOSE:To monitor many transmission and distribution lines correctly at the same time, by a constitution wherein all of the results of inspections with respect to the transmission and distribution lines, which are obtained by a multitude of sensors, are collected into a computer through slave stations, master stations and personal computers. CONSTITUTION:Signals, obtained by sensor main bodies 5a-8a, are propagated through optical fibers 5c-8c and are inputted into sensor devices 5b-8b, then, the results of inspections are outputted to slave stations 2, 2, 2. A master station 3 and three sets of slave stations 2, 2, 2 are connected through a main circuit optical fiber 9 and an auxiliary circuit optical fiber 10 and respective slave stations 2 output the obtained results of inspections to the main circuit optical fiber 9 to collect them into the master station 3. The master station 3 outputs the result of inspection to a personal computer 4. The personal computer 4 obtains the processing result of one unit of one monitor unit 1. Then, the personal computers 4 output the obtained processing results to the main circuit optical fiber 19 to collect them into a computer 14 and process all of informations from respective personal computers 4 systematically. |
