Abstract
A structure monitor system comprising a measuring unit 3 for measuring distortions of the structure S at respective points on a boundary by using an optical fiber sensor 2 laid on the boundary of the structure, numerical analysis unit 5 for calculating a distortion at a specified point on the structure S by a numerical analysis method with distortions measured by the measuring unit as a boundary condition, and a display unit 6 for displaying information on an analysis distortion by the numerical analysis unit 5 in a association with a position on the structure S.
Claims24
A structure monitor system for analyzing a temperature, a distortion or a like physical quantity at a specified point of a structure, in which the physical quantity at one point on a boundary or inside of the structure is expressed by a governing equation, by a numerical analysis method by setting a specific boundary condition, and monitoring the structure based on the analysis result, comprising:
- a measuring means for, using an optical fiber sensor laid on the boundary of the structure, measuring physical quantities of the structure at points on the boundary of the structure where the optical fiber sensor is laid,
