Isihlaziyi Somsindo Sangaphansi Kwamanzi se-UNAS
I-UNAS Underwater Noise Analyzer iyisistimu yesikhathi sangempela yokuhlaziya nokudlulisa umsindo ongaphansi kwamanzi. Yakhelwe phezu kwamandla ayisisekelo ekusebenziseni amandla aphansi nomsindo ophansi wangaphakathi, isekela izindlela zokusebenza ezimbili: ukuqopha okuzenzakalelayo kanye nokudlulisa okuku-inthanethi ngesikhathi sangempela. Inomklamo omncane futhi olula, idivayisi ingafakwa kuma-buoy, amapulatifomu aphansi olwandle, noma amapulatifomu okubuka eselula. Ifakwe ibhethri elakhelwe ngaphakathi eliphinde lishajwe elinikeza ukuqina okuzenzakalelayo kwe-≥Amahora angu-48; ngaphandle kwalokho, inganikwa amandla yipulatifomu yokusingatha ukuze kuqashwe isikhathi eside, ku-inthanethi njalo, kudluliswe idatha yomsindo wesikhathi sangempela kanye nolwazi lwe-spectral nge-interface ye-Ethernet noma ye-RS485.
Amayunithi amaningi angasebenzisa iwashi lepulatifomu yomsingathi ukuze kube lula ukubonwa okusatshalalisiwe nokuvumelanisiwe ngokunemba kokuvumelanisa okungcono kune-1μs. Uhlelo lusetshenziswa kabanzi emikhakheni efana nokuqapha umsindo wasolwandle ku-inthanethi, ukulandelela imisindo yezilwane ezincelisayo zasolwandle, kanye nokuhlolwa komsindo wobunjiniyela bangaphansi kwamanzi, futhi lutholakala ezinguqulweni ezenzelwe kokubili izindawo zasogwini kanye nezijulile zolwandle.
