A kind of broken wire monitoring method and system based on cable or boom

Abstract

The invention discloses a broken wire monitoring method and system based on a cable or a suspender. The method first obtains the broken wire acoustic emission signal collected by multiple acoustic emission sensors on a single cable or suspender; The acoustic emission signal of each broken wire is used to determine the characteristic parameters of each broken wire acoustic emission; finally, the final number of broken wires and the position of each broken wire of a single cable or boom are determined according to each of the said broken wire acoustic emission characteristic parameters, realizing all-day monitoring This method not only reduces the operating conditions and the danger of working at heights, but also improves the monitoring effect.

Description

technical field [0001] The invention relates to the technical field of broken wire monitoring, in particular to a method and system for monitoring broken wires based on a cable or a suspender. Background technique [0002] Bridge cables and suspenders are important structural components of bridges, and their damage status during service is closely related to the health status of the bridge. To avoid accidents such as bridge collapse and damage, it is imperative to monitor the cables and suspenders. [0003] Cable and boom protection devices often have waterproof and anti-corrosion functions and cannot be easily opened; the conventional monitoring methods for broken wires of cables and booms are electromagnetic, ultrasonic flaw detection, magnetic flux, etc., but existing cables and booms are broken. The silk monitoring method has disadvantages such as time-consuming and labor-intensive, poor effect, high operating conditions, and dangerous high-altitude operations. It is als...

[0003] Cable and boom protection devices often have waterproof and anti-corrosion functions and cannot be easily opened; the conventional monitoring methods for broken wires of cables and booms are electromagnetic, ultrasonic flaw detection, magnetic flux, etc., but existing cables and booms are broken. The silk monitoring method has disadvantages such as time-consuming and labor-intensive, poor effect, high operating conditions, and dangerous high-altitude operations, and it is difficult to meet the requirements of all-weather monitoring, let alone the corresponding early warning prompts
