Monitoring system and monitoring method for the whole process of section steel component damage

Abstract

The invention discloses a system for monitoring the whole damage process of a profile steel member. The system comprises a movable control platform, a magnetic sensing probe and a control system. Themovable control platform is used for being arranged on the profile steel member. The magnetic sensing probe is arranged on the movable control platform, and the movable control platform drives the magnetic sensing probe to move to obtain three-dimensional magnetic induction intensity of the profile steel member. The control system is in communication with the movable control platform and the magnetic sensing probe to control the movable control platform and the magnetic sensing probe to work, and the damage position and the damage size which are developed by the profile steel member along withthe time and the load are calculated according to information fed back by the movable control platform and the magnetic sensing probe. The invention further discloses a method for monitoring the whole damage process of the profile steel member. According to the system and method for monitoring the whole damage process of the profile steel member, the purpose of damage monitoring and early-warningfor the profile steel member in a complicated and severe service environment is achieved, oil paint and surface-layer sheaths do not need to be removed, the use of steel structures is not influenced,and the operation is simple. Moreover, the whole damage process can be monitored, and meanwhile, the damage position and the damage size are monitored.

Description

technical field [0001] The invention relates to the technical field of damage monitoring, in particular to a damage monitoring system and a monitoring method for the whole process of steel member damage. Background technique [0002] The damage of traditional steel components mainly depends on manual monitoring. During monitoring, it is necessary to remove the steel structure paint, sheath and other protective layers, and mainly observe the external damage degree of the steel structure. This method has low work efficiency and poor accuracy, and requires a lot of manpower. Under the action of wind and rain, high-altitude operations pose a great threat to the safety of surveyors. [0003] In the past two decades, the damage monitoring methods of steel components mainly include resistance strain gauge method, magnetic flux leakage monitoring method, ultrasonic wave, magnetic memory technology, acoustic emission technology, piezoelectric material-polyvinylidene fluoride sensing ...

AI Technical Summary

Problems solved by technology

[0005] Based on this, it is necessary to provide a monitoring system and method for the whole process of steel component damage in view of the problems that the traditional section steel monitoring method is cumbersome to operate, cannot identify the whole process of damage, and cannot identify the damage location and damage size at the same time
