Research on the Optimization and Evaluation of Excavator Human-Machine Interface Layout Based on Situation Awareness

Abstract

In order to solve the problem of a large number of types and complex layouts of control devices on the operator interface of mining excavators, and a large variety and number of control elements on the control panel, the layout optimization design is carried out by applying the theoretical model of situational awareness and the influencing factors to the layout design of the human-machine interface. The modularity of the interface and the hierarchy of the original components are divided, and the importance evaluation indicators established according to situational awareness are weighted according to the entropy weighting method, and then the results are combined with the VIKOR method to analyse the importance of the interface components and the control panel module respectively before the interface is optimised and designed. The results show that the application of situational awareness theory to HMI design can play an important role in enhancing the level of situational awareness of operators and meeting their needs.
