Crack monitoring management system and monitoring management method

Abstract

The invention discloses a crack monitoring and management system, which comprises a field monitoring and resolving system, a cloud platform computing and management system and a client viewing system;the field monitoring resolving system comprises an intelligent camera and characteristic targets; the characteristic targets are arranged on the two sides of crack, and the intelligent camera recognizes and observes the characteristic targets arranged on the two sides of crack, monitors whether the characteristic targets arranged on the two sides of the crack generate relative displacement or not, resolves relative displacement data x of the characteristic targets arranged on the two sides of the crack, and uploads the relative displacement data x to a cloud platform computing management system; in an initial state, a monitoring person measures the initial cracking distance x1 of a crack and inputs the monitored initial cracking distance x1 of the crack to the cloud platform computing management system through the client viewing system; and in a real-time monitoring state, after the cloud platform computing management system receives the relative displacement data x, input by the intelligent camera, of the characteristic targets on the two sides of the corresponding crack, the cracking degree X = x1 + delta x of the crack is calculated in real time.

Description

technical field

[0001] The invention relates to the technical field of structure crack monitoring and management, in particular to a crack monitoring and management system and a monitoring and management method based on machine vision technology. Background technique

[0002] After different structures (such as bridges, tunnels, etc.) are put into use, in addition to bearing various natural loads, they will also inevitably bear driving dynamic loads, overloads or impacts, etc., which will inevitably cause structural mechanical or structural performance. Changes, this internal change will be manifested in the form of cracks. In order to understand the safety status of the structure, it is necessary to conduct long-term safety monitoring of the cracks that appear on it to prevent accidents such as the collapse of the structure.

[0003] The traditional crack monitoring method installs a rod-type crack meter or a rope-type crack meter at the crack. When the crack is opened, the...
