Umsebenzi wokusebenza kanye namaphoyinti wokufaka we-radar abuyiselwe emuva
Igama eligcwele le-radar elibuyisa kabusha "libuyisela emuva i-radar elwa nokushayisana", ebizwa nangokuthi "ukupaka idivaysi ezayo", noma "ukubuyela emuva uhlelo lokuxwayisa ikhompyutha". Idivayisi ingahlulela ibanga lezingqinamba futhi yelule isimo sezingqinamba ezizungeze imoto ukuthuthukisa ukuphepha kokubuyiselwa emuva.
Okokuqala, umgomo wokusebenza
Ukubuyela emuva i-radar kuyinto yokuphepha ephephile yokuphepha, ehlanganiswa nge-sensor ye-ultrasonic (eyaziwa ngokuthi yi-probe), isilawuli kanye nesibonisi, i-alamu (uphondo (inzwa ye-ultrasonic yingxenye esemqoka yohlelo lonke lokubuyisela emuva kohlelo lonke lwe-Helsersing. Umsebenzi wayo ukuthumela nokwamukela amagagasi e-ultrasonic. Isakhiwo saso sikhonjiswa kuMfanekiso 2 Ngokuvamile, kukhuphuka imvamisa, kukhuphuka ukuzwela, kepha ukuqondiswa okuvundlile nokume mpo kwe-angle yokutholwa kuncane, ngakho-ke sebenzisa i-40Khz Probe
Astr Radar amukele umgomo wokuqhamuka kwe-ultrasonic. Lapho imoto ifakwa egiya le-reverse, i-radar ehlekisayo ingena ngokuzenzakalelayo isimo esisebenzayo. Ngaphansi kokulawulwa kwesilawuli, ukuphenywa okufakwe phezu kwe-bumper engemuva kuthumela amagagasi e-ultrasonic futhi kwakha amasiginali e-echo lapho ehlangabezana nezingqinamba. Ngemuva kokuthola amasiginali we-echo avela enzwa, isilawuli sithwala ukucubungula idatha, ngaleyo ndlela sibala ibanga phakathi komzimba wezimoto nezingqinamba kanye nokwahlulela isikhundla sezingqinamba.
Ukubuyisela emuva i-radar circuity block block block njengoba kukhonjisiwe kuMdwebo 3, uMcu (MicroprocessorTroluint) Ngokwakheka kohlelo oluhleliwe, lawula umjikelezo wokuhambisa we-Analog Shintsha we-Analog Shintsha, umsebenzi we-Ultrasonic. Izimpawu ze-echo ze-Ultrasonic zicutshungulwa ngokuthola okukhethekile, ukuhlunga futhi zikhulisa amasekethe, bese kutholakala amachweba ayi-10 e-MCU. Lapho uthola isibonakaliso sengxenye ephelele yenzwa, uhlelo luthola ibanga eliseduze ngokusebenzisa i-algorithm ethile, futhi ishayela i-buzzer noma isibonise umjikelezo ukukhumbuza umshayeli webanga eliseduzane Challecy ibanga ne-azimuth.
Umsebenzi oyinhloko wohlelo lokubuyisela emuva kwe-radar ukusiza ukupaka, ukuphuma kwegiya lokubuyela emuva noma ukuyeka ukusebenza lapho isivinini esishukumisayo esidlula ijubane elithile (imvamisa 5km / h).
[Ithiphu] i-ultrasonic wave ibhekisela kwigagasi lomsindo elidlula uhla lokuzwa komuntu (ngenhla kwe-20KHZ). Inezimpawu zemvamisa ephezulu, ukusakazwa komugqa oqondile, ukuqondiswa okuhle, ukungafani okuncane, ukungena okunamandla, isivinini sokusakaza kancane (cishe ama-340m / cishe. Amagagasi e-Ultrasonic ahamba nge-Opaque Solids futhi angangena ekujuleni kwamashumi amamitha. Lapho i-ultrasonic ihlangabezana nokungcola noma ukufaka phakathi, izokhiqiza amagagasi abonisiwe, angasetshenziselwa ukwakha ukutholwa okujulile noma ukusukela, futhi ngenxa yalokho kungenziwa ngohlelo olusuka khona.
