摘要:
针对关于滑坡引起管道变形的研究存在测量累积误差大、无法标定,以及没有考虑突发变形的测量与表征的问题,提出倾斜信息与振动信息融合的一体化光纤光栅传感与信息处理方法。首先,分别研究了分布式光纤光栅倾角测点模式下管道累积变形和突发变形下管道振动信息的感知方法,建立起了突发变形和累积变形计算的理论基础。然后,提出了基于递归变分模式提取( RVME )的光纤光栅测斜多组分信号的分解算法,其有效地解决了传统变模式分解算法( VMD )所存在的中心频率和惩罚因子难以确定的问题。最后,通过自主研制传感器和搭建实验台,在同时施加横向位移和冲击振动的情况下,利用提出的基于 RVME 的光纤光栅测斜信号分解方法,实现对多点位测斜管内实测倾斜信号与振动信号的分离,具有较高的工程实际应用价值。
Abstract:
To address the issues of significant cumulative measurement errors , the inability to calibrate , and the lack of consideration for sudden deformations in studies on pipeline deformation caused by landslides , this paper proposes an integrated fiber Bragg grating sensing and information processing method that fuses inclination and vibration information.Firstly , the principle of Cumulative deformation of pipes under the mode of distributed fiber grating dip measurement points and the sensing method of vibration information under the sudden deformation of pipe are studied respectively.Thus , the theoretical basis for the calculation of sudden deformation and cumulative deformation is established.Then , a decomposition algorithm of fiber grating inclinometer multi component signals based on recursive variational mode extraction ( RVME ) is proposed , which effectively solves the problem of central frequency and penalty factor difficult to be determined in the traditional variable mode decomposition ( VMD ) algorithms.Finally , through the self-developed sensor and the construction of the experimental platform , under the condition of applying lateral displacement and impact vibration at the same time , the separation of tilt information and vibration information has been successfully performed by the decomposition method of fiber grating inclinometer signal based on RVME.The experimental results show that the researched method has high engineering application value.
