Simultaneously sampled remote data reading and transmission system using optical fibers

摘要

A system for sampling and collecting simultaneously data from terminal apparatus installed at a plurality of data measuring locations (data sources) distributed in a system to be monitored or controlled by using at least a single optical fiber includes means for initiating sampling of measured quantities in response to a synchronizing signal supplied-from a master station, and means for allotting to the terminal apparatus respective particular time slots during which the data as measured is transmitted to the master station through at least a single optical fiber.
