Kodi radar ya microwave yamagalimoto ndi chiyani?
Radar ya microwave yamagalimoto ndi njira ya radar yomwe imagwiritsa ntchito ma microwave kuti izindikire, makamaka yomwe imagwiritsidwa ntchito m'magalimoto ndi magalimoto ena apansi. Radar ya microwave imazindikira zinthu zomwe zili m'malo ozungulira potumiza ndikulandira zizindikiro za microwave, kuti ikwaniritse ntchito zosiyanasiyana, monga kuzindikira zopinga, chenjezo la kugundana, kuwongolera kayendedwe ka sitima, ndi zina zotero.
Mfundo yogwirira ntchito
Radar ya microwave yamagalimoto imagwira ntchito mofanana ndi radar wamba, ndiko kuti, imatumiza mafunde opanda zingwe (microwave) kenako imalandira echo malinga ndi kusiyana kwa nthawi pakati pa kulandira ndi kulandira, kuti iyese deta ya malo a cholinga. Makamaka, ma radar a microwave amatulutsa zizindikiro za microwave zomwe zimabwerera m'mbuyo akakumana ndi zopinga, ndipo radar imawerengera mtunda poyesa nthawi yobwerera ya zizindikiro. Kuphatikiza apo, radar ya microwave imathanso kuzindikira liwiro ndi komwe chinthucho chikupita pofufuza makhalidwe a chizindikiro chowonetsedwa, monga Doppler effect .
Chitsanzo cha ntchito
Radar ya microwave yamagalimoto ili ndi zochitika zosiyanasiyana zogwiritsidwa ntchito m'magalimoto:
Chenjezo la kugundana : mwa kuzindikira zopinga zomwe zili patsogolo, chenjezo loyambirira, thandizani dalaivala kutenga njira zopewera kugundana .
Kuwongolera kayendedwe ka sitima yapamadzi kosinthika: Kumasintha liwiro la kayendedwe ka sitima yapamadzi molingana ndi malo ozungulira galimotoyo, kusunga mtunda wotetezeka kuchokera ku galimoto yomwe ili patsogolo.
Kuzindikira oyenda pansi: Mu dongosolo loyendetsa lokha, radar ya microwave imatha kuzindikira oyenda pansi ndi zopinga zina kuti zitsimikizire kuti kuyendetsa bwino.
Kuyimitsa galimoto yokha: Thandizani galimotoyo kupeza malo oyenera oimikapo magalimoto pamalo oimikapo magalimoto ndikumaliza ntchito yoyimitsa galimotoyo.
Magawo aukadaulo ndi makhalidwe a magwiridwe antchito
Ma radar a ma microwave a magalimoto nthawi zambiri amagwira ntchito m'magawo a mafunde a millimeter, monga 24GHz, okhala ndi ma frequency apamwamba komanso ma wavelength afupiafupi. Izi zimapangitsa kuti ma microwave radar akhale ndi chitsogozo chapamwamba komanso kutsimikiza, ndipo amatha kuzindikira molondola zolinga zapafupi. Kuphatikiza apo, ma microwave radar sakhudzidwa ndi kuwoneka bwino ndipo amatha kugwira ntchito bwino nyengo ikaipa. Komabe, mtengo wa ma microwave radar ndi wokwera, ndipo kuthekera kozindikira zinthu zazing'ono sikwabwino ngati lidar .
Ntchito zazikulu za radar ya microwave yamagalimoto zikuphatikizapo zinthu izi:
Chenjezo la Kugundana ndi Kukonza Mabuleki Mwadzidzidzi (AEB): Ma rada a microwave amazindikira zopinga patsogolo ndipo ngati pakufunika kuyambitsa makina okonza mabuleki mwadzidzidzi kuti apewe kugundana.
Kuzindikira oyenda pansi: Kudzera mu radar ya microwave, magalimoto amatha kuzindikira ndi kuzindikira oyenda pansi, motero kupititsa patsogolo chitetezo choyendetsa.
Chenjezo la Kuyang'anira Malo Osaona ndi Kuchoka kwa Njira: Radar ya microwave imatha kuyang'anira malo osaona a galimoto kuti isagunde magalimoto ena akamasintha misewu, ndipo imatha kuyang'anira kuchoka kwa msewu ndikudziwitsa oyendetsa.
Kuwongolera maulendo apamadzi (ACC): Rada ya microwave ingathandize magalimoto kukhala kutali ndi galimoto patsogolo pa chowongolera maulendo apamadzi chosinthika.
Chenjezo la Magalimoto Akumbuyo (RCTA): Radar ya microwave imatha kuyang'anira magalimoto kumbuyo kwa galimotoyo, kukumbutsa dalaivala kuti azisamala ndi galimoto yomwe ikubwera, kuti apewe kugundana ndi galimotoyo.
Mfundo yogwira ntchito ya radar ya microwave ndikuyesa malo a chandamale potumiza mafunde opanda zingwe (mafunde a radar) ndikulandira echo malinga ndi kusiyana kwa nthawi pakati pa kutumiza ndi kulandira. Mafupipafupi a radar ya mafunde a millimeter ali mu gulu la mafunde a millimeter, kotero amatchedwa millimeter wave radar .
Kugwiritsa ntchito ma frequency band osiyanasiyana a microwave radar m'magalimoto kumaphatikizapo ma band awiri a 24GHz ndi 77GHz. Ma radar a 24GHz amagwiritsidwa ntchito makamaka pozindikira ma radar afupiafupi, pomwe ma radar a 77GHz ali ndi resolution yapamwamba komanso kukula kochepa, koyenera kuzindikira ma radar akutali.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
