Kungani izinzwa zokupaka ziye zayeka ukusebenza (izizathu, ukuxilonga, ukulungisa)
Okuqukethwe
I-Parktronic ingumsizi odingekayo futhi obalulekile wabaqalayo nabashayeli bezimoto abanolwazi. Uhlelo lusiza ukugwema ukungqubuzana nezithiyo lapho wenza umsebenzi wokupaka. Ngokuvamile, abashayeli bezimoto abasafufusa ababoni izikhala, ama-curbs aphakeme nezinye izithiyo lapho behlehla.
Ukuze kuvikelwe abashayeli ezingozini ezingenangqondo, kunezinzwa zokupaka noma ama-radar okupaka. Lawa amadivaysi e-elekthronikhi futhi ngezikhathi ezithile ayahluleka ngenxa yezizathu ezihlukahlukene.
Ngokwesisekelo salesi simiso, amadivaysi alula nawo ayasebenza - i-echo sounder yokudoba, kanye nezinzwa zokupaka zabashayeli bezimoto.
Ngaphakathi kwenzwa, ungathola ipuleti le-piezoceramic. Inyakaza kumaza we-ultrasonic, njengesipikha ohlelweni lomsindo. I-Ultrasound isetshenziswa kuphela ngoba kulula kakhulu ukuyisebenzisa, ngokungafani namaza omsakazo afanayo. Asikho isidingo sama-antenna, imininingwane kanye nokugunyazwa.
Leli puleti liwuthi lwe-transceiver. Iyunithi yokulawula ngokwayo ixhuma ipuleti kujeneretha we-ultrasound kanye nomamukeli.
Ngemva kokukhiqiza isignali ye-ultrasonic, lapho iqala ukunyakaza, ipuleti lisebenza njengomamukeli. Ibhulokhi ngalesi sikhathi isivele ilinganisela isikhathi sokunyakaza kwesignali nokubuya kwayo emuva.
Izinzwa zokupaka zikagesi zihlelwe ngendlela ehlukile, kodwa isimiso asihlukile ku-radar yakudala. Lapha, i-tape ekhethekile ye-aluminium isetshenziswa njengenzwa. Le tape kufanele ifakwe ngemuva kwebhampa.
Umehluko omkhulu phakathi kwezinzwa zokupaka zikagesi ukuthi azisebenzi kuphela lapho imoto ihamba noma lapho izithiyo zihamba. Idivayisi ayiphenduli ebangeni lesithiyo, kodwa ekushintsheni kuleli banga.
Ukungasebenzi kahle kwezinzwa zokupaka
Phakathi kokungasebenzi kahle kwamadivayisi kukhona:
Umshado. Lokhu kuyinto evamile, ikakhulukazi uma ucabangela ukuthi inqwaba yeziphakamiso emakethe yenziwa eChina. Le nkinga ingaxazululwa kuphela ngokubuyisela izinzwa zokupaka kumdayisi noma umenzi;
Amaphutha ezintambo, izinzwa noma itheyiphu ezindaweni zokufakwa kwayo kubhampa;
Ukungasebenzi kahle kweyunithi - Lena inkinga eyivelakancane. Amayunithi okulawula wezinzwa zokupaka ezisezingeni eliphezulu afakwe ngesistimu yawo yokuxilonga futhi uma kunenkinga, umshayeli ngokuqinisekile uzothola umlayezo noma uhlobo oluthile lwesignali;
Izinkinga ngezinzwa noma itheyiphu ngenxa yokungcola, uthuli, umswakama. Izinzwa ze-Ultrasonic zingahluleka ngisho nomthelela omncane wetshe.
I-tape idinga ukuhlanzwa njalo, okumele ihlakazwe. Inzwa ye-ultrasonic ayesabi ikakhulukazi ukungcola nomswakama. Kodwa umswakama uvame ukunqwabelana bese ukhubaza isici;
Isilawuli sokulawula izinzwa zokupaka ngokuvamile ziyehluleka futhi ngenxa yokungcola namanzi. Ngokuvamile, izifunda ezimfushane zitholakala ekuhlolweni kwesidumbu;
Elinye iphutha lithi izintambo. Inkinga ayivamile neze. Lokhu kungavunyelwa phakathi nenqubo yokufaka isistimu emotweni.
Izindlela zokuxilonga nezindlela zokulungisa
Umsebenzi oyinhloko we-radar yokupaka ukwazisa umshayeli ngesithiyo ngemuva noma phambi kwemoto.
Uma idivayisi ingakhiphi noma yiziphi izimpawu noma ikhiqiza amasignali ngamaphutha, udinga ukuqonda izimbangela futhi uziqede, kodwa okokuqala kufanelekile ukwenza ukuxilongwa okuphelele.
Ukuhlola inzwa
Uma i-radar isebenze ngaphambili, kodwa ngokuzumayo iyeka, isinyathelo sokuqala ukuhlola isimo sezinzwa ze-ultrasonic - zingase zibe ukungcola noma uthuli. Lapho uhlanza izinzwa, ukunakwa akukhokhelwa kuphela izakhi ngokwazo, kodwa futhi endaweni yokukhuphuka. Kubalulekile ukuthi ukukhweza inzwa kuvikelekile.
Uma ukuhlanza kungasebenzi, kufanele uqiniseke ukuthi izakhi ziyasebenza. Ukuhlola lokhu kulula kakhulu - umshayeli udinga ukuvula ukuthungela, bese uthinta inzwa ngayinye ngomunwe. Uma inzwa isebenza, izodlidliza futhi iqhekeke. Uma kungekho okuqhekeka lapho kuthintwa ngomunwe, inzwa ishintshela kwentsha. Kwesinye isikhathi izinzwa zingalungiswa.
Uma usebenzisa umunwe kwakungenzeka ukunquma ukuthi iyiphi yezinzwa ku-bumper engasebenzi, ngakho-ke ngaphambi kokuthatha isinyathelo esibucayi, kufanelekile ukomisa isici kahle. Ngezinye izikhathi, ngemva kokoma ngokuphelele, izinzwa ziqala ukusebenza. Uma lokhu kungenzeki, ungabheka isici nge-multimeter.
Inzwa inokuxhumana nogesi - amanye amamodeli anokuxhumana okubili kanye nokuthathu. Kwesobunxele kuma-elementi amaningi - "ubuningi". Umhloli ushintshelwa kumodi yokulinganisa ukumelana. I-probe eyodwa ixhunywe "ebuningini", kanti eyesibili - koxhumana naye wesibili.
Uma idivayisi ibonisa ukuthi ukumelana kukhulu kunoziro futhi akulingani nokungapheli, khona-ke inzwa isesimweni sokusebenza. Kuzo zonke ezinye izimo, inzwa inephutha futhi idinga ukushintshwa.
Ungahlola futhi i-wiring nge-multimeter. Ukuze wenze lokhu, hlola zonke izintambo lapho inzwa ixhunywe khona kuyunithi yokulawula. Uma kutholakala ukungasebenzi okuvulekile noma okunye kwesekethe kagesi, khona-ke i-wiring yokubuyisela inzwa ethile iyadingeka.
Lawula ukuhlola kweyunithi
Iyunithi ivikelwe ngokuthembekile kumswakama nokungcola futhi kuyaqabukela ihluleka - ifakwe endaweni yabagibeli, futhi zonke izintambo ezivela ezinzwa zixhunywe kuyo kusetshenziswa izintambo noma ngaphandle kwentambo.
Uma kwenzeka kunenkinga, ungasusa ibhodi lesifunda eliphrintiwe futhi ulihlole ngokubukeka - uma ama-capacitor awonakele noma ama-resistors abonakala, khona-ke angashintshwa kalula ngama-analogue atholakalayo.
Ihlola itheyiphu ye-radar yokupaka enensimbi
Ngokuqondene namateyipu ensimbi, konke kulula kakhulu. I-tape inomshini olula, uma kungewona owokuqala - ukungasebenzi kahle kungenzeka kuphela ngenxa yokulimala ngokomzimba.
Yonke inqubo yokuxilonga iyancipha ekuhloleni okubonakalayo okuphelele. Kuyadingeka ukunaka ngisho neziphambeko ezincane - imihuzuko, imifantu.
Uma ubuqotho be-tape bungaphulwa, ngakho-ke kunconywa ukuthi ubheke izimbangela zokungasebenzi kahle noma yikuphi, ngoba i-tape ayihlangene nayo.
Ungakugwema kanjani ukuphuka kwezinzwa zokupaka esikhathini esizayo
Ukuze ugweme izinkinga nge-radar yokupaka, kubalulekile ukuqapha njalo isimo sezinzwa. Uma kukhona ukungcola ezakhini zesakhiwo, kufanele zihlanzwe kahle ngokushesha. Okufanayo kuya ngomswakama.
Ngaphezu kokufaka okufanele, ukulungiswa okunekhono nakho kuyadingeka. Uma izinzwa zizwela kakhulu, idivayisi izosabela ngisho notshani. Uma, ngokuphambene nalokho, iphansi kakhulu, khona-ke idivayisi ingase ingaboni umgqomo omkhulu kakhonkolo noma ibhentshi.
