Fatigue intervention system and device based on electroencephalogram

Abstract

The invention discloses an electroencephalogram-based fatigue intervention system and device, and the system comprises an electroencephalogram collection module which at least comprises a first electrode and is used for collecting electroencephalogram data of a target through the first electrode; the transcranial electrical stimulation module at least comprises a second electrode and is used for applying weak-current electrical stimulation signals to the target through the second electrode according to the stimulation instruction, and the electrical stimulation signals comprise direct current stimulation signals or alternating current stimulation signals or random noise signals; and the processing module is used for acquiring the electroencephalogram data fed back by the electroencephalogram acquisition module and matching the stimulation instruction according to the electroencephalogram data. The invention provides a system and a device which are mild in stimulation, not easy to interfere, obvious in interference effect and capable of effectively recovering fatigue.

Description

technical field [0001] The present invention relates to an EEG-based fatigue intervention device, in particular to an EEG-based fatigue intervention system and device. Background technique [0002] Modern technological societies rely on 24-hour operations or shift work in industries such as transportation, nursing, manufacturing, military, aviation, hospitals, and many public services. People working shifts primarily disrupt sleep and circadian rhythms. Disruption of the circadian cycle and sleep deprivation can also lead to reduced waking alertness, impairment and fatigue. Second, certain occupations with high work pressure (such as nuclear power plant operators) can also cause psychological fatigue. When people are in a state of physical fatigue or mental fatigue, their cognitive ability will decline, which has a great negative impact on safe production or safe work (such as fatigued driving). Therefore, it is necessary to detect fatigue and implement specific intervent...

Problems solved by technology

The way of visual reminder is mainly to display the fatigue results on the host computer or monitor in the background. This kind of visual stimulation is not obvious and requires a third party to monitor the fatigue status in real time and perform manual intervention

The sound reminder is more effective than the visual reminder, but the effective duration of the intervention is short (less than 10 seconds), and it will have a certain effect on mild fatigue, but the effect on severe fatigue is not obvious

Visual reminder and sound reminder are the two m
