Abstract

The invention relates to a physical fatigue detection method based on a brain network topology law and a system, and the method comprises the steps: collecting hemoglobin information in a brain, and recording a subjective evaluation scale and a behavioral test result before and after a tested fatigue induction experiment; preprocessing the acquired cerebral hemoglobin information; classifying the preprocessed cerebral hemoglobin information according to physical fatigue levels according to the subjective evaluation scale and the behavioral test result, calculating the correlation between the brain regions, and respectively counting brain network connection topology laws corresponding to the physical fatigue levels; wherein the brain network connection topology law is common representation corresponding to fatigue induced by various tasks; and according to the brain network connection topology law, constructing a specific statistical difference change graph corresponding to the brain area connection correlation between every two physical fatigue levels. According to the invention, the specific state of fatigue can be detected in real time, and early warning is facilitated.

Description

technical field [0001] The present invention relates to the technical field of fatigue detection, in particular to a physical fatigue detection method and system based on brain network topological rules. Background technique [0002] Physical fatigue is a common problem in daily life, and it is also one of the important factors affecting work efficiency. Physical fatigue is divided into muscle fatigue, cardiopulmonary fatigue and nervous system fatigue. If you are in a state of excessive physical fatigue for a long time, it can cause many physical and mental diseases and seriously affect your health; at the same time, physical fatigue will reduce the accuracy, efficiency and stability of people's work, and cause work accidents in some fields, such as driving, the Internet, surgery etc. By judging the degree of physical fatigue in real time, we can reasonably arrange work intensity, rest in time, and maintain physical and mental health. In addition, the more important thin...
