Method and device for monitoring active state of ship driver based on physical channel

The invention discloses a ship driver active state monitoring method based on a physical channel. The method comprises the following steps: A, acquiring on-duty state information of a driver; b, analyzing the amplitude and phase of the state information; c, preprocessing the amplitude and the phase, and screening high-correlation data of the on-duty state of the driver; d, performing multi-level dispersion feature extraction to obtain dispersion features, and selecting an optimal feature value group by using a data evaluation algorithm; e, screening an optimal characteristic value, classifying by using a support vector machine, and identifying the number of people on duty; f, an activeness evaluation system is established, activeness evaluation is carried out, and the driver on-duty activeness is obtained; and G, constructing a minimum activeness standard of the operator on duty, and judging whether the operator is in a safe navigation state. The invention further discloses a ship driver active state monitori
