Blood glucose prediction method and device based on optical signal characteristics and metabolic heat characteristics

Abstract

The embodiment of the invention relates to a blood glucose prediction method and device based on optical signal characteristics and metabolic heat characteristics. The method comprises the following steps: acquiring first calibrated blood glucose data; collecting and generating first, second, third and fourth optical signals; collecting and generating first, second, third, fourth, fifth, sixth and seventh metabolic heat signals; carrying out human body optical signal feature extraction and normalization processing to generate first, second and third optical feature data sets; performing environment light signal feature extraction and normalization processing to generate fourth optical feature data; performing metabolic heat feature extraction and normalization processing to generate first, second, third, fourth, fifth, sixth and seventh metabolic heat feature data; performing feature fusion processing to generate a first feature vector; performing floating blood glucose value prediction based on a blood glucose floating prediction model to generate first floating blood glucose data; and generating first predicted blood glucose data according to the sum of the first calibrated blood glucose data and the first floating blood glucose data. According to the invention, a noninvasive blood glucose observation mechanism can be provided.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a blood sugar prediction method and device based on optical signal features and metabolic heat features. Background technique [0002] Glucose in the blood is called blood sugar (Glu). Maintaining blood sugar at a certain level can maintain the normal work of various organs and tissues in the body. Short-term blood sugar instability will cause various degrees of discomfort in various organs and tissues, and long-term blood sugar instability may lead to various degrees of lesions in various organs and tissues. Therefore, the observed value of blood glucose is a very important health evaluation parameter in the field of health monitoring. The current common blood glucose monitoring method is mainly based on the extraction of human blood in an invasive way, and chemical analysis is performed on the extracted blood to obtain the blood glucose observation value. Because this...
