This utility model belongs to the field of metal sheet forming and processing technology, specifically disclosing a device for detecting bending defects in aluminum curtain wall panels. The device includes a workbench with a through-hole mounting groove on its end face. A bending assembly is installed within the mounting groove. A clamping assembly is located below the workbench, and a mounting base is located above the workbench. The bending assembly includes two support plates symmetrically fixed to the side walls of the mounting groove, forming a bending channel one between the two support plates. Each support plate has a downward-sloping surface on its end face away from the mounting groove, making the opening of bending channel one larger as it approaches the clamping assembly. A bending roller and a hinged bending plate are respectively installed above the two support plates, forming a bending channel two between them. This bending channel two connects with bending channel one to form a channel to be bent. This device solves the problem of aluminum sheet performance being damaged due to excessive bending defects during the bending process in current devices.

This invention specifically relates to a gas concentration measurement method, aiming to address the technical problems of existing gas concentration measurement methods, such as systematic inversion bias, sensitivity to environmental conditions, insufficient robustness to changes in system response, difficulty in balancing computational complexity and real-time performance, and insufficient inversion stability under low signal-to-noise ratio conditions. This invention detects a target area to obtain a reference spectral image, a spectral image of the gas to be measured, and a water vapor spectral image. Through dark-field and flat-field correction, it obtains the reference equivalent radiance, the equivalent radiance of the gas to be measured, and the equivalent radiance of water vapor. Normalization is performed using the reference equivalent radiance to obtain the logarithmic absorbance of the gas to be measured and the logarithmic absorbance of water vapor. Water vapor absorption interference is subtracted using the logarithmic absorbance of water vapor, finally yielding the concentration of the gas to be measured. This reduces the influence of water vapor absorption on the detection results and improves inversion stability.
