T\u00e4h\u00e4n kehitykseen eri s\u00e4hk\u00f6ntuottamisen teollisuuden alat ovat joutuneet vastaamaan lis\u00e4\u00e4m\u00e4ll\u00e4 tuotantokapasiteettiaan. Uusiutuvista energiamuodoista tuulienergia on lis\u00e4nnyt tuotantokapasiteettiaan ehk\u00e4 eniten. Koko kehityksens\u00e4 ajan tuulienergian tuotantokapasiteetin lis\u00e4\u00e4ntyminen on ollut eksponentiaalista ja t\u00e4m\u00e4n kehityksen ennustetaan my\u00f6s jatkuvan.\r\nSamaan aikaan kilpailu tuuliturbiinien osien valmistajien v\u00e4lill\u00e4 kiristyy. Eritt\u00e4in t\u00e4rke\u00e4n\u00e4 osana kilpailussa on tuotteen mukana myyt\u00e4v\u00e4t palvelut. T\u00e4st\u00e4 hyv\u00e4 esimerkki on tuuliturbiinien vaihteiden valmistajan Moventaksen myym\u00e4 kunnonvalvontaj\u00e4rjestelm\u00e4.

Vaihteilta tulevia v\u00e4r\u00e4htelyspektrej\u00e4 tulee p\u00e4ivitt\u00e4in tuhansia.

Lis\u00e4ksi tulevaisuudessa analysoitavien v\u00e4r\u00e4htelyspektrien m\u00e4\u00e4r\u00e4n odotetaan kasvavan. T\u00e4h\u00e4n haasteeseen l\u00e4hdettiin kehitt\u00e4m\u00e4\u00e4n algoritmia, joka analysoisi v\u00e4r\u00e4htelyspektrit automaattisesti.\r\nAlgoritmin kehitt\u00e4misess\u00e4 haasteena oli saada algoritmista geneerinen siten, ett\u00e4 se toimisi hyvin eri vaihdetyyppien, v\u00e4r\u00e4htelyanturien ja spektrityyppien kanssa. Algoritmin toimintaa verrattiin manuaaliseen analysointiin ottamalla er\u00e4\u00e4n vaihdetyypin vikaantuneita vaihteita ja katsomalla, kuinka nopeasti algoritmi havaitsee vaihteen vikaantumiseen. Tulokseksi saatiin, ett\u00e4 algoritmi reagoi keskim\u00e4\u00e4rin 13,5 p\u00e4iv\u00e4\u00e4 aikaisemmin kuin mit\u00e4 vikaantumisiin on reagoitu manuaalisen analysointity\u00f6n kautta.\r\nTulevaisuudessa algoritmia pyrit\u00e4\u00e4n kehitt\u00e4m\u00e4\u00e4n siten, ett\u00e4 sen analysoimat spektrit lajiteltaisiin niiden kiinnostavuuden mukaan, jolloin j\u00e4rjestelm\u00e4 antaisi analysoitsijalle vain merkitt\u00e4vimm\u00e4t spektrit.
