Concrete recognition method based on photochromic material

Abstract

The invention discloses a concrete recognition method based on a photochromic material. The concrete recognition method comprises the following steps: generating a first two-dimensional code; settinga photochromic material with a set color on the surface layer of the product according to the first two-dimensional code; detecting and drawing a second two-dimensional code; and comparing and judgingwhether the concrete product is authentic. The photochromic material is arranged on the surface layer of the concrete product, so that the mark can be prevented from being abraded and falling off. The concrete mark is easier to read. The photochromic material is arranged in a two-dimensional code mode, the characteristic of higher safety is achieved, and compared with a traditional recognition mode, the method has the beneficial effects of being resistant to altering and not prone to abrasion, and the effect of enhancing the supervision capacity of concrete products is achieved.

Description

technical field [0001] The invention relates to a concrete anti-counterfeit mark, in particular to a concrete mark method based on a photosensitive color-changing material. Background technique [0002] Traditional concrete signs use printing to print simple patterns on the concrete surface, which are easily worn and washed away during transportation or after installation. Printing simple patterns has a limited amount of data stored in patterns, which is not conducive to sign reading and product authenticity. False verification makes it impossible to identify whether it is a genuine concrete product; in concrete production, there are still behaviors such as cutting corners and cheating, and simple patterns are easy to be altered, resulting in easy replacement of products and poor safety, which makes the quality and safety of the project unavoidable. It is difficult to carry out effective supervision without guarantee. Contents of the invention [0003] The object of the p...
