Embodiment 1

[0047] This embodiment provides a fatigue state monitoring and early warning method, including the following steps:

[0048] (1) Preset a fatigue state monitoring and early warning system, which includes a physiological information collection module, a wireless communication module and a monitoring module, wherein the physiological information collection module has a built-in dry state electrode sensor and an intelligent chip, and the monitoring module includes mutual A connected main control unit and an early warning unit, the main control unit includes a preprocessing subunit, a model building subunit and a fusion subunit;

[0049] (2) Regularly collect the electroencephalogram signal of the person under test through the physiological information collection module, the dry electrode sensor in the physiological information collection module collects the bioelectrical signal generated by the brain, and sends the collected bioelectrical signal into the In the smart chip, the sm...

Embodiment 2

[0057] see Image 6 and Figure 7 The main difference between this embodiment and Embodiment 1 is that: the main control unit in the step (1) also includes a feature extraction subunit and a fusion subunit; the step (2) also includes: the physiological information collection module The human eye image signal of the person under test is regularly collected; the step (3) also includes: the wireless communication module transmits the human eye image signal to the monitoring module; the step (4) also includes: the preprocessing subunit Preprocessing the human eye image signal, the preprocessing includes denoising, grayscale and equalization processing on the human eye image signal data; the feature extraction subunit extracts human eye features from the preprocessed human eye image signal, and calculate the human eye fatigue value; the fusion subunit fuses the EEG fatigue value and the human eye fatigue value, analyzes and calculates the fatigue level, and judges whether the meas...

Abstract

The invention discloses a fatigue state monitoring and early warning method comprising the following steps that (1) a fatigue state monitoring and early warning system is preset; (2) the electroencephalographic signals of the tested personnel are acquired in a timing way by a physiological information acquisition module, the physiological information acquisition module acquires the bioelectric signals generated by the brain and transmits the bioelectric signals to a smart chip, and the smart chip filters noise and disturbance of the bioelectric signals and amplifies the useful bioelectric signals after filtering; (3) a wireless communication module transmits the useful bioelectric signals to a monitoring module; (4) the monitoring module analyzes and processes the useful bioelectric signals and judges whether the tested personnel is in the fatigue state; and (5) an early warning unit emits a warning prompt when a master control unit judges that the tested personnel is in the fatigue state. The invention also discloses the fatigue state monitoring and early warning system. According to the fatigue state monitoring and early warning method and system thereof, the anti-interference capability is high, the reliability is high and the judgment speed and accuracy can be enhanced.

Description

technical field [0001] The invention relates to the field of fatigue detection, in particular to a fatigue state monitoring and early warning method and system thereof. Background technique [0002] With the rapid development of China's economy, more and more people have purchased private cars. However, traffic accidents have also increased. The reason is that driver fatigue, especially severe fatigue driving, is an important cause of frequent traffic accidents. Accident statistics show that 35%-45% of traffic fatalities can be attributed to driving fatigue. Driving fatigue can affect various aspects such as driver's attention, feeling, consciousness, thinking, judgment, will, decision and motion. Drivers may be in fatigue driving, and this is extremely dangerous, and currently used to prevent fatigue can be roughly divided into two categories, one is active and the other is passive. The active way is that the driver should ensure enough rest time when he perceives that he...
