Abstract: The present invention relates to a method and a system for predicting a state of fatigue of a driver, in particular an operator of construction machinery, comprising the following steps: acquiring a data sequence of one fatigue parameter or data sequences of multiple fatigue parameters of the driver in at least one current time period; determining, based on the acquired data sequence(s), an optimal data of the one fatigue parameter or of the multiple fatigue parameters corresponding to the most fatigued state of the driver in each of the at least one current time period to generate a model input data in the time period; predicting, by using a trained time series prediction model for fatigue, a model prediction data of the one fatigue parameter or of the multiple fatigue parameters in an expected future time period after the at least one current time period based on the generated model input data; determining the state of the fatigue of the driver in the expected future time period based on the model predictio

Abstract: A system for regulating an environment within an operator cabin of a machine via a heating, ventilation, and air conditioning (HVAC) system includes a first sensor that generates a first signal of an amount of air pressure within the operator cabin, a second sensor that generates a second signal of an amount of carbon dioxide within the operator cabin, an air filtration element to direct pre-cleaned air into the operator cabin, an inlet valve disposed between the air filtration element and the HVAC system for controlling a flowrate of the pre-cleaned air to the HVAC system, and a controller. The controller actuates dynamic auto-control of the inlet valve to direct an optimally varying flowrate of the pre-cleaned air from the air filtration element to the HVAC system via the inlet valve to maximize a service life of the air filtration element.
