Method, device and program product for real-time monitoring of wind-induced vibration displacement of long-span cable net structure

Abstract

The present disclosure provides a large-span cable net structure wind-induced vibration displacement real-time monitoring method, device and program product, relating to the technical field of computers. The wind-induced vibration displacement real-time monitoring method of the present disclosure constructs a fiber optic cable force sensor by laying out a plurality of key monitoring points on the surface of the bearing cable and the surface of the cable, and rigidly fixes a machine vision target at the top of the mast. Real three-dimensional spatial displacement data of the top of the mast is obtained in a short period of time using the constructed binocular camera vision system, and a deep learning network is trained with cable force as input and three-dimensional spatial displacement data as output. The trained network can identify the three-dimensional spatial displacement of the top of the mast in real time based on the cable force, without the need to construct complex mechanical models and structural dynamics equations to accurately characterize the stress path of complex cable net structures, effectively solving the problem of difficulty in modeling by physical methods and difficulty in capturing nonlinear coupling relationships.
