- FREMGANGSMÅDE TIL BESTEMMELSE AF STATIONÆRE SIGNALER TIL DIAGNOSTICERING AF ET ELEKTROMEKANISK SYSTEM1. Fremgangsmåde til bestemmelse af stationære signaler til diagnosticering af et elektromekanisk system, hvilken fremgangsmåde omfatter følgende trin: • måling af et analogt bølgeformet signal (S) fra det elektromekaniske system, • konvertering af det målte bølgeformede signal (S) til et diskret forarbejdet signal (Sdp) indbefattende en vektor for tidspunkter og en tilsvarende amplitudevektor, • opsplitning af det diskrete forarbejdede signal (SDp) i underopdelte enkeltstående perioder (SDP1, SDP2, ..., SDPn), hvor hver af de underopdelte enkeltstående perioder indbefatter forskellige eller det samme antal prøver som andre underopdelte enkeltstående perioder, • ændring af antallet af prøver for hver underopdelte enkeltstående periode (SDPi, Sdp2, , SDPn) ved hjælp afen resampling-procedure, hvorved der opnås underopdelte enkeltstående perioder efter resampling (SDR1, SDR2, ..., SDRn), hvor samtlige underopdelte enkeltstående perioder efter resampling indbefatter det samme antal prøver, • udskiftning af vektoren for tidspunkter på en vektor for konsekutive heltal for hver enkeltstående periode efter resampling (SDri, SDr2, , SDRn), hvorved der opnås underopdelte dimensionsløse enkeltstående perioder {Sdni, SDN2, ... SDNn), • sammenkædning af samtlige underopdelte dimensionsløse enkeltstående perioder (Sdni, Sdnz , SDNn) i ét dimensionsløst diskret signal (SN) ved dannelse af en sekvens af konsekutive prøver opstillet én efter én taget fra konsekutive underopdelte dimensionsløse enkeltstående perioder, • udskiftning af vektoren for konsekutive heltal på en vektor af stigende tidspunkter i det dimensionsløse diskrete signal (SN), hvorved der opnås et dimensioneret stationært signal {SNt), • transformering af det dimensionerede stationære signal (SNt) fra tidsdomæne til frekvensdomæne, hvorved der opnås et frekvensspektrum, hvorfra en vektor af interessante frekvenser og en tilsvarende amplitudevektor udledes til diagnosticering af det elektromekaniske system og vises på visningsenheden.
