[0004] However, in the above-mentioned prior art, when the material composition tables of the standard material composition table and the combined material composition table exist at the same time, the convolution calculation cannot be performed, and the unqualified materials that may have been originally unqualified after the convolution calculation are performed. The content calculation results of some restricted substances are too low to draw qualified conclusions, leading to wrong conclusions that meet the requirements of various environmental protection laws and regulations

Embodiment Construction
[0013] The embodiment of the present invention provides a method and device for determining the content of substances in a product, which is used to perform volume integral calculation when two formats of the material composition table and the composite material composition table exist at the same time, To accurately determine the material composition of the product, so as to accurately judge whether the product or component meets the requirements of various laws and regulations, and can also be used to count the material composition and content, material composition and content of the product or component.
[0014] see figure 1 , an embodiment of the method for determining the content of substances in a product in the implementation of the present invention includes:
[0015] 101. Read the product composition information in the database;
[0016] In this embodiment, the product composition information is stored in the database. When receiving the command input by the user to...

The embodiment of the invention discloses a method and a device for determining matter content in products. The method can determine compositions and content of materials and matters in products or parts through convolution computation. The method provided by the embodiment comprises the following steps: acquiring a material content table of a part according to product composition information in a database; adjusting the form of a standard material content table to a combinative material content table; classifying the matters; calculating the weight of each matter in each part and the total weight of the parts by convolution computation according the type, weight and content of the matters; calculating the content of each material in the part according to the arithmetic mean value of the material weights in each part and the total weight of the parts; calculating the weight of each material in the part by convolution computation; multiplying the weight and content of materials and matters in each part by the number of the parts; and calculating the material composition and matter composition of the product by convolution computation.
Description
technical field [0001] The invention relates to the field of information technology, in particular to a method and device for determining the content of substances in a product. Background technique [0002] The impact of products or parts on the environment has received more and more attention. In order to cope with the current environmental regulations involving electronic and electrical equipment and similar environmental regulations in the future, the requirements for product ingredients and usage ratios need to be accurately counted. Material composition and its content. Since the same component in the product may be supplied by multiple suppliers, it involves the problem of convolution algorithm, that is, how to convolve materials with different material components provided by different suppliers into the material components of the materials used in the product Different convolution algorithms will give different convolution results. [0003] In the prior art, the ma...
