1,Isingeniso
Ukuhlukahluka kwe-Ultrasonickuyindlela yokuthola okungeyena othintana naye esebenzisa amaza e-ultrasonic aphuma emthonjeni womsindo, futhi igagasi le-ultrasonic libonisa emuva emthonjeni womsindo lapho isithiyo sitholwa, futhi ibanga lesithiyo libalwa ngokusekelwe kwisivinini sokusakaza sejubane umsindo emoyeni. Ngenxa yokuqondisa kwayo okuhle kwe-ultrasonic, akuthintwa ukukhanya nombala wento elinganisiwe, ngakho-ke isetshenziswa kabanzi ekugwemeni izithiyo zamarobhothi. Inzwa ingakwazi ukuzwa izithiyo ezimile noma eziguqukayo kumzila wokuhamba werobhothi, futhi ibike ibanga nolwazi lwesiqondiso sezithiyo ngesikhathi sangempela. Irobhothi lingakwazi ukwenza kahle isenzo esilandelayo ngokuya ngolwazi.
Ngokuthuthuka okusheshayo kobuchwepheshe bokusebenzisa irobhothi, amarobhothi emikhakheni ehlukene yezicelo avele emakethe, futhi izidingo ezintsha zibekwe phambili ezinzwa. Ukuzivumelanisa kanjani nokusetshenziswa kwamarobhothi emikhakheni ehlukene kuyinkinga yawo wonke unjiniyela wezinzwa ukuthi acabange futhi ahlole.
Kuleli phepha, ngokusebenzisa inzwa ye-ultrasonic kurobhothi, ukuqonda kangcono ukusetshenziswa kwenzwa yokugwema izithiyo.
2,Isingeniso Senzwa
I-A21, A22 kanye ne-R01 izinzwa eziklanywe ngokusekelwe kuzinhlelo zokusebenza zokulawula irobhothi ezizenzakalelayo, ezinochungechunge lwezinzuzo zendawo encane eyimpumputhe, ukuguquguquka okuqinile kokulinganisa, isikhathi sokuphendula esifushane, ukuphazamiseka kokuhlunga, ukuguquguquka okuphezulu kokufaka, ukumelana nothuli nokungangeni kwamanzi, impilo ende nokuthembeka okuphezulu. njll. Bangakwazi ukuzivumelanisa nezinzwa ezinamapharamitha ahlukene ngokuya ngamarobhothi ahlukene.

3,Imingcele yomkhiqizo
(1)Amapharamitha ayisisekelo
(2)Ibanga lokutholwa
Inzwa yokugwema izithiyo ye-Ultrasonic inenguqulo yama-engeli amabili yokuzikhethela, Uma umkhiqizo ufakwe uqondile, i-engeli evundlile yesokunxele nakwesokudla inkulu, ingakhuphula uhla lokumboza lokugwema izithiyo, i-engeli encane yokubheka isiqondiso, ngesikhathi esifanayo. isikhathi, igwema inhlamvu engalungile ebangelwa umgwaqo ongalingani ngesikhathi sokushayela.
Umdwebo webanga lokulinganisa
4,Uhlelo lobuchwepheshe lokugwema izithiyo ze-Ultrasonic
(1)Umdwebo wesakhiwo sehadiwe
(2)Ukuhamba komsebenzi
a, Inzwa inikwa amandla amasekhethi kagesi.
b, Iphrosesa iqala ukuzihlola ukuze kuqinisekiswe ukuthi isifunda ngasinye sisebenza ngokujwayelekile.
c, Iphrosesa izihlole ukuze ibone ukuthi ingabe ikhona yini isignali yokuphazamiseka ye-ultrasonic-frequency efanayo endaweni ezungezile, bese ihlunga futhi icubungule amaza omsindo alien ngesikhathi. Uma inani elilungile lebanga lingenakunikwa umsebenzisi, nikeza idatha yophawu olungajwayelekile ukuze uvimbele amaphutha, bese weqela enqubweni k.
d, Iphrosesa ithumela iziyalezo kumjikelezo we-boost excitation pulse ukuze ulawule ukushuba kwenjabulo ngokuya nge-engeli nobubanzi.
e, I-ultrasonic probe T idlulisa amasignali acoustic ngemva kokusebenza
f, I-ultrasonic probe R ithola amasiginali we-acoustic ngemva kokusebenza
g, Isiginali ye-acoustic ebuthakathaka ikhuliswa yisekethe ye-amplifier yesiginali futhi ibuyiselwe kuphrosesa.
h, Isignali ekhulisiwe ibuyiselwa kuphrosesa ngemva kokubunjwa, futhi i-algorithm ehlakaniphile eyakhelwe ngaphakathi ihlunga ubuchwepheshe begagasi lomsindo ophazamisayo, obungakwazi ukuhlunga ngempumelelo okuhlosiwe kweqiniso.
i, Isekhethi yokuthola izinga lokushisa, thola impendulo yezinga lokushisa lemvelo yangaphandle kumprosesa
j, Iphrosesa ihlonza isikhathi sokubuya kwe-echo futhi inxephezele izinga lokushisa elihlanganiswe nemvelo ezungezile yangaphandle, ibala inani lebanga (S = V *t/2).
k、Iphrosesa idlulisela isignali yedatha ebaliwe kuklayenti ngomugqa wokuxhuma bese ibuyisela ku-a.
(3)Inqubo yokugxambukela
I-Ultrasound emkhakheni wamarobhothi, izobhekana nemithombo yokuphazamiseka ehlukahlukene, njengomsindo wokunikezwa kwamandla kagesi, ukwehla, ukukhuphuka, okwesikhashana, njll. Ukuphazamiseka kwemisebe yesekethe yokulawula yangaphakathi irobhothi kanye nenjini. I-Ultrasound isebenza ngomoya njengendlela ephakathi. Uma irobhothi lifakwe izinzwa eziningi ze-ultrasonic kanye namarobhothi amaningi esebenza eduze ngesikhathi esisodwa, kuzoba namasignali amaningi okungewona awomdabu endaweni kanye nesikhathi esifanayo, futhi ukugxambukela phakathi kwamarobhothi kuzoba kubi kakhulu.
Ngenxa yalezi zinkinga zokuphazamiseka, inzwa eyakhelwe ngaphakathi kubuchwepheshe bokuzivumelanisa nezimo eziguquguqukayo kakhulu, ingasekela ukumiswa kwezinga lokuncishiswa komsindo wezinga elingu-5, isihlungi esifanayo sokuphazamiseka kokuvama singasethwa, ububanzi kanye ne-engeli ingasethwa, kusetshenziswa i-algorithm yesihlungi se-echo, ikhono eliqinile lokulwa nokuphazamiseka.
Ngemuva kwelabhorethri ye-DYP ngokusebenzisa le ndlela yokuhlola elandelayo: sebenzisa izinzwa zokugwema izithiyo ezi-4 ukuze ubinge isilinganiso, ulingise indawo yokusebenza yemishini eminingi, urekhode idatha, izinga lokunemba kwedatha lifinyelele ngaphezu kwama-98%.
Umdwebo wokuhlolwa kobuchwepheshe bokulwa nokuphazamiseka
(4) I-engeli ye-Beam iyalungiseka
I-engeli ye-sensor ye-sensor yokumisa inamazinga angu-4: 40,45,55,65, ukuhlangabezana nezidingo zohlelo lokusebenza zezimo ezahlukene.
5,Uhlelo lobuchwepheshe lokugwema izithiyo ze-Ultrasonic
Emkhakheni wohlelo lokusebenza lokugwema izithiyo zamarobhothi, inzwa iyiso lerobhothi, Ukuthi irobhothi lingakwazi yini ukunyakaza ngokuguquguqukayo futhi ngokushesha kuncike kakhulu olwazini lokulinganisa olubuyiswe inzwa. Ohlotsheni olufanayo lwezinzwa zokugwema izithiyo ze-ultrasonic, kuyimikhiqizo enokwethenjelwa yokugwema izithiyo enezindleko eziphansi kanye nesivinini esiphansi, imikhiqizo ifakwe eduze kwerobhothi, ukuxhumana nesikhungo sokulawula amarobhothi, qala izinzwa ezihlukene zokutholwa kwebanga ngokusho kwesiqondiso sokunyakaza. yerobhothi, finyelela impendulo esheshayo kanye nezidingo zokutholwa lapho kudingeka khona. Ngaleso sikhathi, inzwa ye-ultrasonic ine-engeli enkulu yenkundla ye-FOV ukusiza umshini uthole isikhala esengeziwe sokulinganisa ukumboza indawo edingekayo yokutholwa ngqo phambi kwayo.
6,Amaphuzu avelele okusetshenziswa kwenzwa ye-ultrasonic ohlelweni lokugwema izithiyo zamarobhothi
• I-radar yokugwema izithiyo ye-Ultrasonic i-FOV ifana nekhamera ejulile, ibiza cishe u-20% wekhamera ejulile;
