Chii chinonzi radar ye microwave yemotokari
Radar ye microwave yemotokari inoshandisa ma microwave kuona, inonyanya kushandiswa mumotokari nedzimwe mota dzepasi. Radar ye microwave inoona zvinhu zviri munzvimbo yakapoteredza nekutumira nekugamuchira masaini e microwave, kuitira kuti iite mabasa akasiyana-siyana, akadai sekuona zvipingamupinyi, yambiro yekurovera, adaptive cruise control, nezvimwewo.
Musimboti wekushanda
Radar ye microwave yemotokari inoshanda zvakafanana neradar yakajairika, kureva kuti, inotumira wave isina waya (microwave) uye yobva yagamuchira echo zvichienderana nemusiyano wenguva pakati pekugamuchira nekugamuchira, kuitira kuti iongorore data renzvimbo yechinangwa. Kunyanya, ma microwave radar anoburitsa ma microwave signals anodzoka shure kana asangana nezvipingamupinyi, uye radar inoverenga daro nekuyera nguva yekudzoka kwema signals. Pamusoro pezvo, microwave radar inogonawo kuona kumhanya negwara rechinhu nekuongorora hunhu hwechiratidzo chinoratidzwa, senge Doppler effect .
Mamiriro ekushandisa
Radar ye microwave yemotokari ine mamiriro akasiyana-siyana ekushandiswa mumotokari:
Yambiro yekuroverana: nekuona zvipingamupinyi zviri mberi, yambiro yekutanga, batsira mutyairi kutora matanho ekudzivirira kuroverana.
Kudzora kufamba kwechikepe kunochinjika: Kunogadzirisa otomatiki kumhanya kwekufamba kwechikepe zvichienderana nenzvimbo yakatenderedza mota, ichichengetedza daro rakachengeteka kubva kumotokari iri pamberi.
Kuona vafambi: Muhurongwa hwekutyaira otomatiki, microwave radar inogona kuona vafambi nezvimwe zvipingamupinyi kuti ive nechokwadi chekuti vatyairi vakachengeteka.
Kupaka otomatiki: Batsira mota kuwana otomatiki nzvimbo chaiyo yekupaka munzvimbo yekupaka uye kupedzisa basa rekupaka otomatiki.
Magadzirirwo ehunyanzvi uye hunhu hwekuita
Ma microwave radar emotokari anowanzo shanda muma millimeter wave bands, akadai se24GHz, ane ma frequency akakwira uye ma wavelength mapfupi. Izvi zvinoita kuti microwave radar ive nedirectivity yakakwira uye resolution, uye inogona kuona nemazvo zvinangwa zviri pedyo. Pamusoro pezvo, microwave radar haikanganisike nekuonekwa uye inogona kushanda zvakajairika mumamiriro ekunze asina kunaka. Zvisinei, mutengo we microwave radar wakakwira, uye kugona kuona zvinhu zvidiki hakuna kunaka se lidar .
Mabasa makuru eradar ye microwave yemotokari anosanganisira zvinhu zvinotevera:
Yambiro Yekurovera uye Kubhureka Kwemotokari Nekukurumidza (AEB): Maradha e microwave anoona zvipingamupinyi zviri mberi uye kana zvichidikanwa anokonzeresa otomatiki yekubhureka motokari nekukurumidza kudzivirira kubonderana.
Kuona vafambi: Kuburikidza ne microwave radar, mota dzinogona kuziva nekuona vafambi, nokudaro zvichivandudza kuchengetedzeka kwekutyaira.
Kutarisa nzvimbo isina chiedza uye yambiro yekubva mumugwagwa: microwave radar inogona kutarisa nzvimbo isina chiedza yemotokari kudzivirira kurovera nedzimwe mota painochinja migwagwa, uye inogona kutarisa kubuda kwemugwagwa uye kuzivisa vatyairi nezve.
Kudzora kufamba kwechikepe (ACC): Radar ye microwave inogona kubatsira mota kuchengetedza daro rakachengeteka kubva kumotokari pamberi pechinodzora kufamba kwechikepe.
Yambiro Yekumashure Kwemotokari (RCTA): microwave radar inogona kutarisa traffic iri kumashure kwemotokari, kuyeuchidza mutyairi kuti ateerere mota iri kuuya, kudzivirira kudzokera shure kurovera .
Nzira inoshanda ye microwave radar ndeyekuyera nzvimbo yechinangwa nekutumira mafungu asina waya (mafungu eradar) uye kugamuchira echo zvichienderana nemusiyano wenguva pakati pekutumira nekugamuchira. Kuwanda kwe millimeter wave radar kuri mu millimeter wave band, saka inonzi millimeter wave radar .
Kushandiswa kwemabhendi akasiyana-siyana e microwave radar mumotokari kunosanganisira mabhendi maviri e 24GHz ne 77GHz. Ma 24GHz radar anonyanya kushandiswa pakuona zviri kure, nepo 77GHz radar dzine resolution yakakwira uye saizi diki, dzakakodzera kuona zviri kure.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
