Automatic online monitoring method and system for cable clamp slippage and readable storage medium

Abstract

The invention belongs to the technical field of bridge construction and relates to an automatic online monitoring method and system for cable clamp slippage and a readable storage medium. Displacementdata, collected by a displacement meter, of a cable clamp relative to a main cable are sampled according to a preset sampling frequency; temperature data collected by a temperature meter are sampled;an average temperature vector T of the same section temperature of the main cable is obtained according to the temperature data; a displacement monitoring vector X of the cable clamp relative to themain cable is obtained according to the displacement data; a corrected cable clamp slippage value is obtained according to a linear correlation equation of the average temperature vector and the displacement monitoring vector. According to the automatic online monitoring device for the cable clamp slippage, cable clamp slippage displacement data and structure temperature near the cable clamp are sampled through the displacement meter and the temperature meter; a temperature meter measurement result and a displacement meter measurement result can be combined; temperature influences are eliminated through algorithm correction, and therefore, the accurate cable clamp slippage value is obtained.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an automatic on-line monitoring method and system for cable clamp slippage, and a readable storage medium. Background technique [0002] The cable clamp is an important component in the suspension bridge. It is a tool to connect the sling and the main cable, and transmit the load on the sling to the important part of the main cable. The cable clamp is usually made of cast steel. The common structure is left and right halves or up and down Two halves. It is fixed and installed at a specific position of the main cable by high-strength bolts, so that the inner wall of the cable clamp can exert pressure on the main cable of the suspension bridge, preventing the cable clamp from sliding down along the main cable of the suspension bridge. [0003] In order to ensure the safety of the suspension bridge, the cable clamp on the main cable of the suspension bridge should be ch...
