Projeto de painel elétrico agroindustrial baseado em modelo de referência: um enfoque na ergonomia cognitiva

Abstract

The physical, cognitive and organization ergonomics may be apllied in several segments of production. Even this topic is poorly studied, its use may benefit agroindustrial units operation, reducing accidents and minimazing workers fatigue. Therefore this subject must keep constant improvements. This study aims to evaluate an electric panel located in a processing plant seeds in Alegrete State of Rio Grande do Sul. The equipment was analyzed based on ergonomic knowledge (work adaptation to man), with emphasis on cognitive ergonomics, which deals with aspects associated with mental activity such as memory, sensation, perception, among others. The proposal for ergonomic improvement of the panel was draw up with the assistance of a computer to redesigned it, poiting improvements related to cognitive and safaty aspects improving its usability. The improvements were made in the configuration of the general buttons, dials (ammeters and voltmeters), closure system and ventilation system of the panel, also adding some safety devices such as emergency button and warning signs labels. After the panel had been redesigned it was concluded that changes in the reference designe helped to enhance the interaction between user and machine, making it more safe and efficiente to the work environment.
