Abstract

Et elektronisk overvåkningssystem for en vinsj som har en girboks med fast forhold mellom inngangs- og utgangsaksler, en vinsjtrommel forbundet med utgangsakselen og en ekstrabrems forbundet med utgangsakselen, som aktiveres ved å redusere trykket i en hydraulisk bremsefrigjøringskrets. Systemet omfatter en inngangsakselhastighetssensor, en utgangsakselhastighetssensor og en elektronisk styringsenhet som har en overvåkningsseksjon og en bremsestyreseksjon. Overvåkningsseksjonen mottar hastighetssignalene, behandler dem for frembringe et beregnet forhold mellom aktuelle inngangs- og utgangsakselhastigheter, og frembringer et feilindikasjonssignal når verdien av forskjellen mellom de beregnede hastighetsforhold og det faste hastighetsforholdet overskrider en forutbestemt verdi. Bremsestyreseksjonen reduser ved mottakelse av feilsignalet, det hydrauliske trykket i bremsekretsen ved å bruke en ikke-lineær trykk/tid-profil for å aktivere ekstrabremsen og stoppe vinsjtrommelen.
