Abstract

The invention discloses a human fatigue monitoring system based on a semantic network. The system comprises all direct influence factors and indirect influence factors causing human fatigue, assumingthat all the direct and indirect influence factors causing the human fatigue are already obtained through all sensors, all the direct factors and indirect factors causing the human fatigue are firstlyclassified, the semantic network representing knowledge in artificial intelligence is used for modeling the relation of all the classified factors, then through a linked probability distribution function and a Bayes equation in the semantic network, solving is conducted, and finally, the human fatigue degree is monitored. The system has robustness and universality.

Description

Technical field [0001] The invention relates to a fatigue monitoring system, in particular to a human fatigue monitoring system based on a semantic network. Background technique [0002] Semantic Network is a mathematical model proposed by Quilian in 1968 when studying human associative memory, and it is a method of knowledge representation. Quilian believes that memory is realized by the connection between concepts. In 1972, artificial intelligence experts Simmon and Slocum first applied the semantic network to a natural language understanding system. The semantic network is a directed network graph that expresses knowledge through concepts and their semantic relations. Among them, the nodes of the directed graph represent various things, concepts, attributes, etc.; arcs represent various semantic relationships between nodes, and indicate a certain semantic relationship between the nodes that it connects. The semantic network can be used to represent complex concepts, things ...
