Abstract

The invention discloses a multi-physiological parameter mental load prediction method and device, and the method comprises the steps: obtaining objective quantity data and subjective quantity data of an operator based on standard experiment tasks with different difficulties; performing data processing on the objective quantity data and the subjective quantity data of the operator to obtain training data; inputting the training data into a plurality of ensemble learning prediction models, and performing voting classification according to prediction results of different ensemble learning prediction models to obtain an optimal ensemble learning model; and performing real-time prediction on the mental load of the operator based on the optimal integrated learning model. By adopting the method and the device in the technical scheme, the mental load of the operator during working can be predicted in real time.

Description

technical field [0001] The invention relates to the technical fields of smart medical treatment and medical health, in particular to a method and device for predicting mental load of multiple physiological parameters. Background technique [0002] Mental load refers to the intellectual resources required by operators to perform various tasks such as calculation, decision-making, and recognition, and its size may be related to the activities of the brain and autonomic systems. At present, the high degree of intelligence in the industry has made the working environment of the operator gradually close to the mental work from the previous manual labor. The amount of information to be processed has increased sharply and the mental resources occupied are higher. Distraction, rapid induction of fatigue, increased human error, increased aversion and frustration will eventually lead to task failure, and it is easy to lead to mental overload and even damage the work when the work pres...
