Abstract

Patente de Invenção: " SISTEMA E PROCESSO DE DIAGNóSTICO DE MáQUINAS". A invenção se refere a um sistema de diagnóstico de máquinas para supervisão de operação de uma máquina, orientada para o estado, que abrange um módulo de valores característicos (5; 105) e um módulo de causas (7; 107). O módulo de valores característicos (5; 105) forma, partindo de valores de medição relacionados com o estado da máquina, valores característicos relevantes para o diagnóstico, e o módulo de causas (7; 107) diagnostica dos valores característicos uma causa para os valores medidos. O módulo de causas (7; 107) calcula, nisso, para pelo menos uma causa possível, cada vez, uma probabilidade de causa, que indica com qual probabilidade a respectiva causa é responsável para a ocorrência dos valores medidos de vibração.
