Active infrared thermal wave detection method and system for glass curtain wall glued structure damage

Abstract

An active infrared thermal detection method for damage in a bonding structure of a glass curtain wall and a system for same, the method comprising: a laser thermal excitation source and an infrared thermal imager are turned on and thermal excitation and collection are performed on a glass curtain wall sample to obtain a temperature curve of a surface of the glass curtain wall; the laser thermal excitation source and the infrared thermal imager are loaded onto an unmanned aircraft or a wall-climbing robot; by means of a temperature / time curve, an optimal scanning sequence between the laser thermal excitation source and the infrared thermal imager is obtained; the laser thermal excitation source and the infrared thermal imager are turned on, and an infrared thermal imager parameter, a thermal image sequence collection frequency, and a thermal excitation power are set; the unmanned aircraft or the wall-climbing robot is caused to fly or move along a glass curtain wall bonding structure at a constant speed to collect thermal radiation passing through the surface of the glass curtain wall; an infrared thermal image sequence of the glass curtain wall bonding structure is obtained and transmitted to a PC terminal; and by means of lag correction, infrared thermal images having clearer temperature differences are obtained, and temperature distribution differences of the infrared thermal images are analyzed to identify a damage condition of the glass curtain wall bonding structure.

Description

technical field [0001] The invention relates to the technical field of glass curtain wall thermal wave detection, in particular to an active thermal excitation type infrared thermal wave detection method and system for glass curtain wall adhesive structure damage. Background technique [0002] The glass curtain wall is a building peripheral structure or decorative structure formed by bonding the support structure and the curtain wall glass through structural adhesives. The main function of the glass curtain wall is to adjust light and heat, resist wind and rain, isolate noise, block air infiltration, and maintain a suitable indoor production and living environment to the maximum extent. In the 1990s, my country's first building with a modern glass curtain wall was built in Guangzhou Canton Fair. Since then, my country's glass curtain wall project has developed rapidly, and its output and usage have increased year by year, gradually becoming a big country of glass curtain wa...

AI Technical Summary

Problems solved by technology

Since the adhesive structure of the glass curtain wall is located between the glass and the supporting structure, it is impossible to directly detect the structural adhesive
