ESTABLISHMENT OF EVALUATION SYSTEM FOR HUMAN-MACHINE INTERFACE IN AGRICULTURAL MACHINERY CAB
Human-machine interface in agricultural machinery cab was defined as the interactive area among the driver and the driving cab components in this paper, which plays a significant role in farming, for it has effect on not only drivers' working efficiency, but also their safety and health. Here, as the representative agricultural machinery cab, the driving components in tractor cab were analyzed, and then the hierarchy system for evaluating the human-machine interface in tractor cab was put forward. Applying the analytical method named analytical hierarchy process (AHP), the questionnaires from twenty-one occupational tractor drivers were analyzed, and the weight of each evaluating index in the hierarchy system was obtained. The results showed that the hand controllers and the visual components in the driving cab performed higher weights than the others, and the position of the cab components affects drivers more seriously than its size commonly. This research was the basic work for evaluating human-machine interface in agricultural machinery cab. In addition, the results could be referenced by the designers in agricultural machinery corporation or institution.
