Concentration detection and training system and method based on functional near-infrared spectroscopy

Abstract

The invention discloses a system and method for concentration detection and training based on functional near infrared spectrum technologies. The system comprises a wearable fNIR sensing device and an intelligent terminal; a fNIR control module in the wearable fNIR sensing device controls switching-on, switching-off and spectral wavelength of a signal emission source in a fNIR signal emission module, switching-on and switching-off of a sensor in a fNIR signal collection module as well as opening and closing of signal channels, and near infrared spectrum signals on each signal channel under different spectrum lengths are collected cyclically and transmitted to the intelligent terminal; and the terminal equipment uses a built-in concentration analysis module to transform the near infrared spectrum signals into hemoglobin content information in real time and then quantify the information into a concentration index.

Description

technical field [0001] The invention discloses a concentration detection and training system and method based on functional near-infrared spectroscopy (fNIR). Background technique [0002] In the existing technology, fNIR functional near-infrared spectroscopy technology is used to measure the content of oxygenated hemoglobin, deoxygenated hemoglobin and total hemoglobin in the cerebral cortex to characterize the response and functional expression of different regions of the brain in the process of receiving external stimuli or thinking. However, the specific sensing devices adopted in the prior art have different defects, some of which are relatively large in size and heavy in weight, and are not suitable for objects to wear. Some use wired data transmission, which limits the scope of use; and the existing technology cannot clarify the relationship between hemoglobin content and concentration, nor can it convert hemoglobin content into concentration scores. Existing technol...
