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

Abstract

The invention discloses an active infrared thermal wave detection method and system for glass curtain wall cementing structure damage, and the method comprises the steps: starting a laser thermal excitation source and a thermal infrared imager, carrying out the thermal excitation and collection of a glass curtain wall sample, and obtaining a glass curtain wall surface temperature curve; loading the laser thermal excitation source and the thermal infrared imager on an unmanned aerial vehicle or a wall climbing robot; obtaining an optimal scanning time sequence between the laser beam and the thermal infrared imager through a temperature and time curve; starting the laser thermal excitation source and the thermal infrared imager, and setting thermal infrared imager parameters, thermal image sequence acquisition frequency and thermal excitation power; enabling the unmanned aerial vehicle or the wall climbing robot to fly or move at a constant speed along the glass curtain wall cementing structure to collect the heat radiation quantity penetrating through the surface of the glass curtain wall; obtaining an infrared thermal image sequence of the glass curtain wall cementing structure andtransmitting the infrared thermal image sequence to a PC terminal; obtaining an infrared thermal image with more obvious temperature difference through delay correction, analyzing the temperature distribution difference of the infrared thermal image, and identifying the damage condition of the glass curtain wall cementing structure.

Description

technical field [0001] The invention relates to the technical field of thermal wave detection of glass curtain walls, in particular to an active thermal excitation infrared thermal wave detection method and system for glass curtain wall glued structure damage. Background technique [0002] The glass curtain wall is a building peripheral structure or decorative structure formed by bonding the supporting structure and the curtain wall glass through structural glue. The main function of 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 greatest 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 projects have developed rapidly, and the output and usage have increased year by year, gradually becoming a big country of glass curtain walls. ...

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
