A method for controlling the quality of industrial processes and system therefrom

摘要

A method for controlling the quality of industrial processes, of the type comprising the steps of: making available one or more reference signals relating to the industrial process acquiring one or more real signals, indicative of the quality of said industrial process, comparing said one or more reference signal to said one or more real signals to identify defects in said industrial process. Said method further includes the operations of: obtaining a real part and an imaginary part from said reference signal; obtaining a real part and an imaginary part from said real signal; computing said real part first comparison dimensions between and said imaginary part from said reference signal; computing second comparison dimensions between said real part and said imaginary part from said real signal; comparing said first comparison dimensions and second comparison dimensions to obtain time location information associated to the presence of defects.
