FIBER-OBTIC SENSOR NETWORK SYSTEM AND METHOD FOR ACQUIRING PHYSICAL INFORMATION THEREBY

摘要

PURPOSE: A fiber-optic sensor network system and a method for obtaining physical information by using the same are provided to implement integrated management of various kinds of fiber-optics sensors with one management device. CONSTITUTION: A fiber-optic sensor measuring unit(110) transmits an optical signal including first and second optical components through which a region is monitored. An optical switch unit(120) switches the transmission route of the optical signal. A plurality of fiber-optic sensors(140) receive the optical signal. The plural optic sensors sense a physical quantity related to the state of the region. The plural fiber-optic sensors transmit a reflected optical signal of a specific wave to the optical switch unit by sensing the physical quantity.
