【Ukuthuthukiswa Komkhiqizo Wedizayini Yezimboni】 Imishini yokubona ukugeleza kwamanzi enemisebenzi eminingi eyinkimbinkimbi
Isingeniso Somkhiqizo
I-velocimeter yokugeleza kwamanzi isebenzisa ubuchwepheshe bokulinganisa ukugeleza kwe-radar okungathintana nabo, obungasetshenziswa esilinganisweni se-hydrologic, ukuqapha kwemithombo yamanzi, ukulawulwa kwezikhukhula zemigwaqo yasemadolobheni, isixwayiso sokuqala kwezikhukhula zezintaba, ukuqapha ukungcoliswa kwemvelo, njll.
Uma kuqhathaniswa nemitha yamanje yokuxhumana ekhona kanye nobuchwepheshe obuhlukahlukene bokulinganisa ukugeleza kwe-Doppler acoustic kanye ne-ultrasonic, indlela yokulinganisa ukugeleza kwe-radar engathinteki kulula ukuyinakekela nganoma yisiphi isikhathi, ngokuyisisekelo ayinawo umonakalo wamanzi, ukugqwala kwendle, kanye nenhlabathi, futhi iqinisekisa ukuphepha kwabasebenzi.Angeke isetshenziselwe kuphela ukuqapha imvelo ngezikhathi ezijwayelekile, kodwa futhi ifaneleka ngokukhethekile ukwenza imisebenzi yokubona ephuthumayo, enzima neyingozi.
Isibonisi somkhiqizo
I-velocimeter yokugeleza kwamanzi iyisizukulwane sesithathu se-radar velocimeter emhlabeni.Isebenzisa isizukulwane esisha se-antenna ye-planar microstrip array, eye yathuthuka kahle kubuchwepheshe uma iqhathaniswa nezizukulwane ezimbili ezedlule ze-radar velocimeter.I-planar microstrip array system idlulisa ukushaya kwe-microwave okufushane kakhulu okungu-1ns.Isikhathi sokusebenza sendiza yesikhathi se-microwave edonsayo silinganiswa kusetshenziswa isivinini se-subband ye-sparse enezinhlangothi ezintathu, i-algorithm yephrofayela yobubanzi kanye nendlela yokwandisa isignali yesizinda sesikhathi, futhi isignali yemvelo ikalwa ngesikhathi esifanayo.Izinga lokugeleza nezinga lamanzi kubalwa ngokusebenzisa indlela yesinxephezelo se-engeli ye-DSP ngokusekelwe kumsindo wesignali yemvelo.Ukusetshenziswa kwamandla okuphansi, ukuhlanganiswa okulula, nokusebenza okuhlukile kokumelana nokuphazamiseka kulungele indawo yokufaka yamaphuzu amaningi ebangeni elifushane.
Izici zobuchwepheshe
Isitholi sesivinini esisuselwe kumgomo wokusebenza we-radar.
I-C plane microstrip radar ukutholwa okungaxhunywana naye, ukusebenza okuzinzile kwesimo sezulu sonke.
Isebenza ezimeni zesivinini esiphezulu ngenkathi yezikhukhula.
Ukunemba kokutholwa okuphezulu, ngesinxephezelo esizenzakalelayo se-engeli eqondile kanye nomsebenzi wesinxephezelo sokulungiselelwa kwe-engeli evundlile.
Ukusetshenziswa kwamandla okuphansi, umklamo wokuvikela amanzi kanye nombani, ofanele izindawo ezihlukahlukene zangaphandle.
Ukubukeka okuncane, ukufakwa kalula nokugcinwa.
Ingaxhunyaniswa ngokuzimela nombuso wamanzi asemadolobheni, indle kanye nemvelo yokuqapha okuzenzakalelayo kanye nohlelo lokubika olusebenzayo.
