用于测量电缆的拉伸应变的变形监视方法和系统
摘要：
本发明提供一种用于至少测量至少一条电缆的拉伸应变的变形监视方法，所述方法包括以下步骤：提供至少一条电缆，所述至少一条电缆包括：应变传感器，所述应变传感器沿所述电缆纵向延伸并且包括布置在弯曲中性区域内的应变光学纤维，所述弯曲中性区域包围并且包括所述电缆的弯曲中性纵向轴线；和至少两个纵向结构元件，所述至少两个纵向结构元件中的至少一个是包括电导体的芯，其中所述应变传感器至少在应变状态中与所述至少两个纵向结构元件中的至少一个机械联接；将第一光学信号引入所述应变光学纤维；检测从所述应变光学纤维发出的布里渊散射光；和分析所述散射光中的光谱变化，以便至少测量所述至少一条电缆的拉伸应变。
摘要（英）：

The invention provides a deformation monitoring method and system for measuring the tensile strain of a cable. The deformation monitoring method comprises the following steps that at least one cable is provided, wherein the cable comprises a strain sensor and at least two longitudinal structure elements, the strain sensor extends in the longitudinal direction of the cable and comprises strain optical fibers arranged in the bending neutral region, the bending neutral region wraps and comprises a bending neutral longitudinal axial line of the cable, at least one longitudinal structure element is a core comprising an electric conductor, and the strain sensor is in mechanical connection with at least one longitudinal structure element at least in the strain state; a first optical signal is introduced into the strain optical fibers; brillouin scattering light emitted by the strain optical fibers is detected; spectral changes of the scattering light are analyzed so that the tensile strain of the cable can be measured at least.
