<p><P>PROBLEM TO BE SOLVED: To provide a temperature measuring system and a method for analyzing a laid state of an optical fiber, capable of easily analyzing a position where the optical fiber is laid actually. <P>SOLUTION: A plurality of tags 13 are attached to the optical fiber 12. A measuring server 16 chooses the tags 13 in order and transmits a positioning processing request signal via a communication base station 14. The chosen tag 13 operates a heating part for heating the optical fiber 12 and outputs a pulse signal, when receiving the positioning processing request signal. The measuring server 16 detects a position of the tag 13 on a two-dimensional or three-dimensional coordinate, based on a pulse signal reception clock time of each communication base station 14, a position of each communication base station 14 and a propagation velocity of the pulse signal. This position information is recorded in a position database 17 along with information of the position of the tag 13 in the longitudinal direction of the optical fiber 12 detected by an optical fiber temperature measuring apparatus 11. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
