Broken wire monitoring method and system based on digging lines or suspension rods

Abstract

The invention discloses a broken wire monitoring method and system based on a digging line or a suspension rod; according to the method, broken wire acoustic emission signals collected by a pluralityof acoustic emission sensors on a single digging line or suspension rod can be firstly obtained; broken wire acoustic emission characteristic parameters can be determined according to the broken wireacoustic emission signals; and the number of final broken wires and the position of each broken wire of the single digging line or suspension rod can be determined according to the broken wire acoustic emission characteristic parameters; the broken wires of the digging line or suspension rod can be monitored in a whole day, and the method not only reduces the operating conditions and the danger ofworking 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
