Problems solved by technology

[0003] However, especially in terms of smell, the current detection is mainly by olfactory experts. The problem brought about by this operation is that the subjectivity of odor testing may cause different olfactory experts to give different results to the same product. Odor scoring, and, in the actual production of polyurethane materials, it is impossible to arrange one or several olfactory experts to conduct odor testing for each batch of products

Abstract

The invention relates to a polyurethane sample quality inspection method, electronic nose equipment and a storage medium. The polyurethane sample quality inspection method comprises the following steps: comparing measured spectrum information of a to-be-inspected polyurethane sample with multiple pieces of reference spectrum information of inspected polyurethane samples, so as to determine reference spectrum information, according with a predetermined confidence interval, of the measured spectrum information, wherein each piece of reference spectrum information is associated with attribute information of the corresponding inspected polyurethane sample; and based on the attribute information associated with the determined reference spectrum information, obtaining a quality inspection resultof the to-be-inspected polyurethane sample.

Description

Technical field [0001] The invention relates to the detection field of polyurethane materials, and more specifically to a quality inspection method of polyurethane samples, an electronic nose device, and a storage medium. Background technique [0002] Polyurethane materials are widely used, for example, in the automotive and furniture fields, such as being made into various automotive interior parts, seats, dashboards, mattresses, sofas, etc. However, because the VOC (volatile organic compounds) and odor of polyurethane materials involve health issues, people expect to buy low-VOC and low-odor polyurethane products. Therefore, it is very important to objectively detect the VOC and odor of these polyurethane products. [0003] However, especially in terms of smell, the current detection of it is mainly done by sniffers. The problem with this operation is that the subjectivity of the odor test may cause different sniffers to give different marks to the same product. Odor score, and...
