Isikali samaloli e-elekthronikhi sisetshenziswa kabanzi emnothweni kazwelonke ngenxa yezimpawu zaso ezilula, ezisheshayo, ezinembile nezinembile.Indlela yokugcina zonke izinhlobo zezikali zamaloli e-elekthronikhi, futhi uthole imbangela yokwehluleka ngokushesha futhi ngokunembile lapho uhlelo luhluleka futhi luthinta ukusetshenziswa, ukuze unciphise isikhathi sokugcina futhi unciphise isikhathi sokuphumula.Lokhu ukukhathazeka okukhulu kwabasebenzisi besikali samaloli.
Isistimu yesikali yeloli ye-elekthronikhi ngokuvamile yakhiwa insimbi yokubonisa isisindo, inzwa yokukala, ukwakheka komshini nezinye izingxenye.Amaphutha ajwayelekile ahlukaniswe kakhulu abe iphutha lensimbi yokukala kanye nephutha lenzwa yokukala.
Ngenxa yesakhiwo esilula sesikali seloli ye-elekthronikhi, lapho iphutha lenzeka futhi imbangela ayikwazi ukugwetshwa, indlela yokuqeda ingasetshenziswa ukuthola imbangela.
Ukuhlolwa kwembangela yokwehluleka kwezinzwa zokukala
I-1.Measure impedance yokufaka, i-impedance yokukhipha, yahlulela ikhwalithi yenzwa.Susa inzwa ezokwahlulelwa kusistimu ngokuhlukana, bese ukala i-impedance yokokufaka kanye nokumelana nokuphumayo ngokulandelanayo.Uma kokubili i-impedance yokokufaka kanye ne-impedance yokukhiphayo kunqanyuliwe, hlola ukuthi ikhebula lesignali yenzwa yokukala inqanyuliwe yini.Uma ikhebuli yesignali ingaguquki, i-sensor strain gauge iyashiswa.Lapho i-impedance yokufaka elinganisiwe kanye namanani okumelana ne-impedance okukhiphayo engazinzile, ungqimba lokufakelwa kwentambo yesiginali lungase lwephuke, ukusebenza kwe-insulation yekhebula lesignali kungase kwehliswe, noma ibhuloho ne-elastomer yenzwa kungase kungagqunywanga kahle ngenxa yomswakama. .
2.Ivelu yesignali enguziro yeseli yomthwalo ngokuvamile incane kuno-±2% wesignali ephumayo yesikali esigcwele.Uma ingaphezu kobubanzi obujwayelekile, kungenzeka ukuthi iseli lomthwalo lilayishwe kakhulu futhi libangele ukuwohloka kwepulasitiki ye-elastomer, ukuze inzwa yokukala ingasetshenziswa.Uma ingekho isignali ephumayo enguziro noma isignali enguziro incane kakhulu, iseli lomthwalo lingase lonakaliswe noma kube khona usekelo lokusekela umzimba wesikali, okuholela ekushintsheni okungabonakali kwenzwa yesisindo se-elastomer.
3. Okokuqala thatha irekhodi lenani lesignali yokukala inzwa engekho umthwalo, bese wengeza umthwalo ofanele endaweni yesikali sesikali seloli, ulinganise ukuguqulwa kwevelu yesignali yokuphuma kwayo, njengokushintsha kwayo kanye nenani lomthwalo kungxenye ehambisanayo, chaza inzwa ngaphandle kwesizathu isithiyo.Uma kufakwa umthwalo ofanele, inani lesignali yokuphumayo alinalo ushintsho olusobala noma ushintsho oluncane uma liqhathaniswa nenani lesignali ephumayo eyiziro, okungenzeka kubangelwe ukunamathela okungalungile phakathi kwegeji yobunzima benzwa nomzimba onwebekayo, noma ukwehluleka okubangelwa umswakama umzimba elastic.Lapho ungeza umthwalo ofanele, isignali yokuphumayo inkulu kakhulu kunevelu yesignali yokuphumayo noma isignali yayo yokuphumayo kwesinye isikhathi evamile ngezinye izikhathi iyahlukahluka kakhulu kungase kube ukuswakama kwekhebula lesignali yenzwa noma ngenxa yokugcwala kwamandla kwenzwa okubangelwa ukuwohloka kwepulasitiki ye-elastomer ayikwazanga ukusetshenziswa, ngesikhathi esifanayo ibhuloho inzwa indlela emfushane futhi kungabangela into enjalo.
