Title:

LINEAR SENSOR-BASED STRUCTURE MONITORING METHOD AND SYSTEM

Document Type and Number:

WIPO Patent Application WO/2022/012099

Kind Code:

A1

Abstract:

A linear sensor (10, 11, 12, 14, 15)-based structure monitoring method and system. The stress, displacement, temperature, or vibration of a target structure is sensed by means of linear sensors (10, 11, 12, 14, 15) comprising a plurality of linear monitoring elements. The linear sensors (10, 11, 12, 14, 15) are first arranged in a net shape in the target structure or on the surface of the target structure; after completing the arrangement, position information of feature points of the linear sensors (10, 11, 12, 14, 15) is obtained; shape curves of the linear sensors (10, 11, 12, 14, 15) are drawn according to the position information of the feature points; the linear monitoring elements obtain and output monitoring data; the monitoring data is marked on the shape curves; the shape curves are updated in real time according to the monitoring data of the linear monitoring elements; and stress state curves of the linear sensors (10, 11, 12, 14, 15) are drawn. In a building structure monitoring system, the shape curves are displayed in a three-dimensional space coordinate system, and the shape curves, the monitoring position, and the stress state curves visually show the overall deformation of a building structure, thereby providing a reliable basis for determination of the structure safety state.
