Ihame ryakazi nogushiraho ingingo zo guhindura radar
Izina ryuzuye rya radar ihinduranya "ni uguhindura radar yo kurwanya kugongana", nanone bita "ibikoresho bifasha guhagarika imodoka", cyangwa "guhindura sisitemu yo kuburira mudasobwa".Igikoresho kirashobora kumenya intera yinzitizi no gutanga inama kubyerekeranye nimbogamizi zikikije ikinyabiziga kugirango umutekano wisubireho.
Icya mbere, ihame ry'akazi
Guhindura radar nigikoresho gifasha umutekano waparika, kigizwe na sensor ya ultrasonic (bakunze kwita probe), kugenzura no kwerekana, gutabaza (ihembe cyangwa buzzer) nibindi bice, nkuko bigaragara ku gishushanyo cya 1. sensor ya Ultrasonic nikintu nyamukuru kigize Sisitemu yose.Igikorwa cyayo nukwohereza no kwakira ultrasonic waves.Imiterere yacyo igaragara ku gishushanyo cya 2. Kugeza ubu, ubusanzwe bukoreshwa bwa probe inshuro 40kHz, 48kHz na 58kHz ubwoko butatu.Mubisanzwe, nukuvuga inshuro nyinshi, niko ibyiyumvo byiyongera, ariko icyerekezo cya horizontal na vertical cyerekezo cyo gutahura Inguni ni ntoya, mubisanzwe rero koresha 40kHz probe
Radar yo mu kirere ifata ihame rya ultrasonic.Iyo ikinyabiziga gishyizwe mubikoresho byinyuma, radar isubira inyuma ihita yinjira mubikorwa.Iyobowe nubugenzuzi, iperereza ryashyizwe kumurongo winyuma ryohereza imiraba ya ultrasonic kandi itanga ibimenyetso bya echo mugihe uhuye nimbogamizi.Nyuma yo kwakira ibimenyetso bya echo biva kuri sensor, umugenzuzi akora gutunganya amakuru, bityo akabara intera iri hagati yumubiri wikinyabiziga n'inzitizi no gusuzuma aho inzitizi zihagaze.
Guhindura radar yumuzunguruko wibishushanyo mbonera nkuko bigaragara ku gishushanyo cya 3, MCU (MicroprocessorControlUint) ukoresheje igishushanyo mbonera cya gahunda, kugenzura imiyoboro ya elegitoroniki ya elegitoronike ihinduranya imiyoboro, ibyuma bya ultrasonic bikora.Ibimenyetso bya Ultrasonic echo bitunganywa no kwakira bidasanzwe, kuyungurura no kongera imiyoboro, hanyuma bikamenyekana ku byambu 10 bya MCU.Iyo wakiriye ibimenyetso byigice cyuzuye cya sensor, sisitemu ibona intera yegeranye ikoresheje algorithm yihariye, kandi igatwara buzzer cyangwa kwerekana umuzenguruko kugirango yibutse umushoferi intera iri hafi yinzitizi na azimuth.
Igikorwa nyamukuru cya sisitemu yo gusubiza inyuma ni ugufasha guhagarara, gusohoka ibikoresho byinyuma cyangwa guhagarika akazi mugihe umuvuduko ugereranije urenze umuvuduko runaka (mubisanzwe 5km / h).
[Impanuro] Umuhengeri Ultrasonic bivuga umuyaga wijwi urenze urwego rwo kumva kwabantu (hejuru ya 20kHz).Ifite ibiranga inshuro nyinshi, gukwirakwiza umurongo ugororotse, kuyobora neza, gutandukana guto, kwinjira cyane, kwihuta gukwirakwira (hafi 340m / s) nibindi.Ultrasonic waves igenda inyura mumashanyarazi kandi irashobora kwinjira mubwimbye bwa metero mirongo.Iyo ultrasonic ihuye numwanda cyangwa intera, izabyara imiraba igaragara, ishobora gukoreshwa mugukora ubushakashatsi bwimbitse cyangwa buringaniye, bityo birashobora gukorwa muburyo butandukanye.
