Chii chinonzi mota microwave radar
Yemotokari microwave radar huturi hweradar inoshandisa microwaves kuona, inonyanya kushandiswa mumotokari nedzimwe mota dzepasi. Microwave radar inoona zvinhu zviri munharaunda yakatenderedza nekutumira uye kugamuchira masaini emicrowave, kuitira kuti uwane mabasa akasiyana siyana, sekuona zvipingaidzo, yambiro yekudhumhana, adaptive cruise control, nezvimwe.
Kushanda musimboti
Motokari microwave radar inoshanda zvakafanana neyakajairwa radar, ndiko kuti, inotumira isina waya wave (microwave) uye yobva yagashira iyo echo zvichienderana nemusiyano wenguva pakati pekugamuchira nekugamuchira, kuitira kuyera chinzvimbo data chechinangwa. Kunyanya, microwave radars inoburitsa microwave masiginecha ayo anodzokera kumashure kana asangana nezvipingamupinyi, uye radar inoverengera chinhambwe nekuyera nguva yekudzoka-kudzoka kwezviratidzo. Pamusoro pezvo, microwave radar inokwanisawo kuona kumhanya uye kutungamira kwechinhu nekuongorora hunhu hwechiratidzo chinoratidzwa, senge Doppler athari.
Mamiriro ekushandisa
Mota microwave radar ine akasiyana emamiriro ekushandisa mumotokari:
yambiro yekudhumhana : nekuona zvipingamupinyi zviri mberi, yambiro yekukurumidza, batsira mutyairi kutora matanho ekudzivirira kudhumhana.
adaptive cruise control : Inogadzirisa otomatiki kumhanya kwe cruise control zvinoenderana nenharaunda yemotokari, kuchengetedza chinhambwe chakachengeteka kubva kumotokari iri kumberi.
Kuonekwa kwevanofamba netsoka : Muiyo otomatiki yekutyaira system, microwave radar inogona kuona vanofamba netsoka uye zvimwe zvipingamupinyi kuona kuchengetedza kutyaira.
otomatiki kupaka : Batsira mota iwane otomatiki nzvimbo yekupaka munzvimbo yekupaka uye pedzisa basa rekupaka.
Technical parameters uye maitiro ekuita
Mota microwave radars dzinowanzo shanda mumamillimeter wave mabhendi, senge 24GHz, ane ma frequency epamusoro uye mapfupi masaisai. Izvi zvinoita kuti microwave radar ive nepamusoro-directivity uye kugadziriswa, uye inogona kunyatsoona yepedyo-renji tarisiro. Mukuwedzera, iyo microwave radar haina kukanganiswa nekuonekwa uye inogona kushanda zvakajairika mumamiriro ekunze akaipa. Nekudaro, mutengo we microwave radar wakakwira, uye kugona kuona zvinhu zvidiki hakuna kunaka se lidar.
Iwo makuru mabasa emotokari microwave radar anosanganisira zvinotevera zvinhu:
Collision Warning uye Automatic Emergency Braking (AEB) : Microwave radars inoona zvipingamupinyi mberi uye kana zvichidikanwa anokonzeresa otomatiki emergency braking system kudzivirira kudhumhana.
kucherechedzwa kwevanofamba netsoka : Kuburikidza nemicrowave radar, mota dzinogona kuziva nekuona vanofamba netsoka, nekudaro dzichivandudza kuchengetedza kwekutyaira.
Blind spot monitoring and lane Yambiro yeKusimuka : microwave radar inokwanisa kutarisa nzvimbo isingaonekwi yemotokari kudzivirira kudhumhana nedzimwe mota pakuchinja nzira, uye inokwanisa kutarisa mafambiro enzira uye kunyevera vatyairi kuenda.
Adaptive cruise control (ACC) : Microwave radar inogona kubatsira mota kuchengetedza chinhambwe chakachengeteka kubva pamotokari pamberi peiyo adaptive cruise control.
Rear Traffic Warning (RCTA) : microwave radar inogona kutarisa traffic kuseri kwemota, yeuchidza mutyairi kuti ateerere kumota iri kuuya, kudzivirira kudzosera kumashure kudhumhana.
Nheyo yekushanda ye microwave radar ndeyekuyera chinzvimbo chechinangwa nekutumira mafungu asina waya (radar waves) uye kugamuchira echo zvichienderana nemusiyano wenguva pakati pekutumira nekugamuchira. Iyo frequency ye millimeter wave radar iri mumillimeter wave bhendi, saka inodaidzwa kuti millimeter wave radar.
Kushandiswa kwemabhendi akasiyana emicrowave radar mumotokari kunosanganisira mabhendi maviri e24GHz uye 77GHz. 24GHz radars anonyanya kushandiswa kuona mapfupi-renji, nepo 77GHz radars ine yakakwirira resolution uye diki saizi, yakakodzera kutarisisa kureba.
