Description

Technical field [0001] The present disclosure relates to the field of blood glucose monitoring, and in particular, to non-invasive blood sugar monitoring methods, systems, equipment and media based on PPG signals. Background technique [0002] The statement of this section is merely a background technique related to the present disclosure and is not necessarily constituting the prior art. [0003] In the process of implementing the present disclosure, the inventors have found the following technical problems in the prior art: [0004] Diabetes is a lifetime metabolic disease that is characterized by a variety of causes caused by chronic hyperglycemia. Diabetes is a chronic disease that cannot be cured, but it can be appropriately managed to control diabetes. About 1.7% of people in the world suffers from diabetes, and this ratio may increase in the near future. Diabetes is divided into four types depending on the mechanism of the onset, of which the topic is the most type I and t...
