Umsebenzi wesihlungi se-antenna yezimoto
I-Youdaoplaceholder0 Imisebenzi esemqoka yesihlungi se-antenna yemoto ihlanganisa izici ezilandelayo:
I-Youdaoplaceholder0 Ukuhlunga isignali nokucindezelwa kokuphazamiseka : Izihlungi ze-antenna zezimoto zingakwazi ukuhlunga izingxenye zefrikhwensi ezingafuneki, zithuthukise ukumelana nokuphazamiseka kwesignali kanye nesilinganiso sesignali-kumsindo. Lokhu kusho ukuthi iqinisekisa ukuthi amasiginali awusizo ayadlula ngenkathi icindezela amasiginali wefrikhwensi engadingeki, ngaleyo ndlela inciphise ukuphazamiseka kokuxhumana futhi ithuthukise ikhwalithi yokuxhumana.
I-Youdaoplaceholder0 Thuthukisa ikhwalithi yokuxhumana : Ngokuhlunga izingxenye zefrikhwensi ezingafuneki, izihlungi ziqinisekisa ukudluliselwa okushelelayo kwamasignali kumaza athile, ngaleyo ndlela kuthuthukiswe ikhwalithi yokuxhumana. Lokhu kubaluleke kakhulu ezinhlelweni zokucubungula isignali yefrikhwensi yeziteshi eziyisisekelo kanye nemishini yokugcina ukuze kuqinisekiswe ukudluliswa okucacile nokuthembekile.
I-Youdaoplaceholder0 Yehlisa ukugxambukela kukazibuthe kagesi : Izihlungi zinganciphisa kakhulu amasiginali wokuphazamiseka kazibuthe futhi ziwavimbele ukuthi angangeni kugridi yamandla, ngaleyo ndlela zivikele indawo ye-electromagnetic ekungcoleni. Lokhu KUBALULEKILE kakhulu ekuvimbeleni ukuphazamiseka kwe-electromagnetic ukuthikameze ezinye izinto zikagesi.
I-Youdaoplaceholder0 Thuthukisa ukunemba kokuhlaziya : Kuzinhlelo zokusebenza ezinjengokuhlaziywa kwe-spectrum, izihlungi zingathuthukisa ukunemba kokuhlaziya ngokukhetha ububanzi obukhethekile bokuhlaziya. Lokhu kwenza ukucutshungulwa kwesignali kunembe kakhudlwana futhi kunikeza ukuqonda okungcono kwezici nezakhiwo zesignali.
I-Youdaoplaceholder0 Isibonelo esiqondile sohlelo lokusebenza : Izihlungi ezinembe kakhulu zisetshenziswa kakhulu emikhiqizweni yezinti zezimoto zikashaka. Lolu hlobo lwe-antenna alugcini nje ngokubukeka kwemfashini nokushintshashintshayo, kodwa futhi luhlanganisa imisebenzi eminingi efana ne-FM, i-GPS ne-GSM. Ukusetshenziswa kwezihlungi ezinemba okuphezulu kunikeza i-antenna ukuthi ikwazi ukucubungula amasignali ahlukahlukene kahle futhi iqinisekisa ikhwalithi yokuxhumana.
Isihlungi se-antenna yemoto i-Youdaoplaceholder0 yisihlungi esiklanyelwe ngokukhethekile izinti zemoto, umsebenzi waso oyinhloko uwukuhlunga amasignali angafuneki amafrikhwensi ukuze kuqinisekiswe ukuthi uthi ithola amasiginali oyifunayo.
Incazelo kanye Nomsebenzi
Isihlungi se-antenna yemoto siyingxenye ye-elekthronikhi, evamise ukufakwa phezu noma eduze nothi lwemoto, olusetshenziselwa ukuhlunga amasiginali wefrikhwensi angafuneki. Umsebenzi wayo oyinhloko ukunciphisa umsindo nokuphazamiseka esignali, ukuqinisekisa ikhwalithi ephezulu yesiginali eyamukelwe, futhi ngaleyo ndlela kuthuthukise ukusebenza nokuzinza kwemishini yokuxhumana.
Isakhiwo kanye nomgomo wokusebenza
Izihlungi ze-antenna zezimoto zakhiwe ngama-capacitor, ama-inductors nama-resistors, futhi zisebenzisa izici zikagesi zalezi zingxenye ukuze zikhethe ukuvumela noma ukunciphisa amasignali amaza athile. Ivumela amasiginali wamafrikhwensi athile ukuthi adlule ngenkathi icindezela amaza angafuneki, ngaleyo ndlela ibhekane nenkinga yokuphazanyiswa kwesignali phakathi kwamabhendi efrikhwensi ahlukene nezinhlelo zokuxhumana.
Izimo zohlelo lokusebenza
Izihlungi ze-antenna zezimoto zisetshenziswa kakhulu kumishini ehlukene yokuxhumana yezimoto, okuhlanganisa imisakazo egibele imoto, izinhlelo zokuzulazula ze-GPS, amamojula okuxhumana angenantambo, njll. Iqinisekisa ukusebenza okuzinzile kwalawa madivayisi endaweni eyinkimbinkimbi kazibuthe, inciphisa ukuphazamiseka kwangaphandle futhi ithuthukisa ikhwalithi yokwamukela isignali .
I-Youdaoplaceholder0 Ukwehluleka kwesihlungi se-antenna yemoto kungabangelwa izizathu ezahlukahlukene, ikakhulukazi ezihlanganisa lezi ezilandelayo:
Ukulimala komzimba we-Youdaoplaceholder0 : Izingxenye ezingaphakathi kwesihlungi (njengama-capacitor, inductors, resistors) zingase zehluleke ngenxa yokulimala komzimba, okuholela ekusebenzeni kabi kokuhlunga noma ukwehluleka okuphelele.
Ukuhlukahluka kwezinga lokushisa kwe-Youdaoplaceholder0 : Ukushintsha kokusebenza kwesihlungi emazingeni okushisa ahlukene kungase kubangele ukusabela okungavamile kwefrikhwensi noma ukukhukhuleka kwezinga lokushisa, kuthinte umphumela wokuhlunga.
Ukungafani kwe-Youdaoplaceholder0 Impedance : Uma okokufaka noma ukuthikamezeka kwesihlungi kungafani nalokho kwesistimu, kuzodala ukulahleka kwesignali noma ukuboniswa, kuthinte ukusebenza kwesistimu.
I-Youdaoplaceholder0 Ukuhluleka komshini : Uma indlu yokuhlunga ilimele noma izixhumi zixega, kungase kubangele ukwehla kokusebenza kwesihlungi noma ukwehluleka okuphelele.
Indlela yokuthola amaphutha
I-Youdaoplaceholder0 Ukuhlolwa kokusebenza kukagesi : Ukuhlola ukusebenza kukagesi kungasetshenziswa ukuthola ukuthi ukumelana, amandla kanye namanye amapharamitha wesihlungi ajwayelekile, ngaleyo ndlela kutholwe ukuthi zikhona yini izinkinga ezifana namasekhethi amafushane noma amasekhethi avuliwe .
I-Youdaoplaceholder0 Ukuhlolwa kwe-X-ray : Isistimu yokuhlola i-X-ray ingasetshenziswa ukuze kutholwe ukuthi azikho yini izinto zangaphandle noma umonakalo wesakhiwo ngaphakathi kwesihlungi, kusize ukuthola imbangela yephutha.
Ukuhlaziywa kwesigaba se-Youdaoplaceholder0 Metallographic : Ngokuhlaziywa kwesigaba se-metallographic, ukwakheka kwangaphakathi nezinto zokuhlunga zingabonwa, kuphinde kutholwe imbangela yephutha.
Izindlela zokuxazulula izinkinga
Youdaoplaceholder0 Faka esikhundleni izingxenye ezilimele : Uma ingxenye engaphakathi kwesihlungi itholwa yonakalisiwe, ingxenye eyonakele ingashintshwa ukuze kubuyiselwe ukusebenza okuvamile kwesihlungi .
I-Youdaoplaceholder0 Lungisa idizayini : Ngokungahambisani kahle noma ukukhukhuleka kwezinga lokushisa okubangelwa izinkinga zedizayini, ukusebenza kwesihlungi kungathuthukiswa ngokulungisa amapharamitha wedizayini.
I-Youdaoplaceholder0 Lungisa amaphutha emishini : Ngamaphutha emishini, ungalungisa izindlu ezilimele noma uqinise izingxenye ezixegayo ukuze uqinisekise ukusebenza okuzinzile kwesihlungi.
