Abstract

The invention provides a mental fatigue detection system and a method adopted by the detection system. The system comprises an information collection module, a data processing module and an analysis and evaluation module, wherein the analysis and evaluation module comprises a BP (back-propagation) neural network judging module; and by virtue of the BP neural network judging module, critical fusion frequency, a power spectrum ratio and a power spectrum entropy undergo fusion judgement by virtue of a BP neural network method, so that mental fatigue status of a tested object is evaluated and analyzed. In comparison with the prior art, the embodiment mode provided by the invention, which conducts fusion judgment on the critical fusion frequency, the power spectrum ratio and the power spectrum entropy by virtue of the BP neural network method, is relatively high in accuracy and relatively short in required data length when used for evaluating and analyzing the mental fatigue status of the tested object, so that real-time detection is satisfied.

Description

technical field [0001] The invention relates to a fatigue detection system and a method thereof, in particular to a multi-parameter fusion fatigue detection system and a method thereof. Background technique [0002] Physiological mental fatigue refers to the weakening of the body's response ability caused by excessive physical or mental energy consumption, excessive stimulation, and excessive pressure during the labor process. Mental fatigue leads to weakened people's work functions, slow thinking responses, and decreased concentration. At present, the traditional detection methods of mental fatigue include biochemical method, physiological reaction measurement method and subjective evaluation method, but all of them have great limitations in practical application because they cannot be detected in real time and the evaluation standards are not easy to unify. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a mental f...
