Kugwira Ntchito ndi Kukhazikitsa Malangizo Obwezeretsa Radar
Dzinalo lonse la radar lotembenuza ndi "kubwezeretsanso radar radar", lotchedwanso "chipangizo choyimira poixiliary", kapena "kubwezeretsa chenjezo la mapulomu". Chipangizocho chingathe kuweruza mtunda wa zopinga ndikulangiza momwe zopinga zimayendera mozungulira galimoto kuti zithetse chitetezo chosintha.
Choyamba, chogwira ntchito
Kubwezeretsa radar ndi chipangizo chogwiritsira ntchito poyendetsa galimoto, chomwe chimapangidwa ndi sensor sensor (chodziwika bwino monga chowonetsera) Ntchito yake ndikutumiza ndikulandila mafunde akupanga. Kapangidwe kake kamawonetsedwa pa Chithunzi 2. Pakadali pano, probe yomwe imagwiritsidwa ntchito kawirikawiri yogwiritsa ntchito kayendedwe ka 40kHz, 48khz ndi 58khz atatu. Nthawi zambiri, kupambana kwapamwamba, chidwi chokwera, koma chopingasa komanso chopingasa cha makona ake ndi chocheperako, kotero gwiritsani ntchito 40kHz
Atsiritsani ma radar amatengera mawonekedwe akupanga. Galimoto ikaikidwanso magiya osinthika, radiya yotembenuza imangogwira ntchito. Mothandizidwa ndi wolamulira, Probe idakhazikitsidwa kumbuyo kwa bumper amatumiza mafunde akupanga ndikupanga zizindikiro za Echo mukakumana ndi zopinga. Mukalandira zizindikiro za Echo kuchokera ku sensor, wowongolera amanyamula pokonza deta, motero amawerengera mtunda pakati pa thupi lagalimoto ndi zopinga ndi kuweruza malo opingasa.
Kubwezeretsa chithunzi cha ma radar Clock Clock monga momwe chithunzi 3, MCU (microprocescorcorliorliuliuliuliuliuliuliulior) kudzera mu kapangidwe kake kansalu, sinthani ma exent ensait, akupanga exesors amagwira ntchito. Akupanga echo signals amakonzedwa ndi kulandira mwapadera, kusefa ndikuwakulitsira madera, kenako ndikupezeka ndi madoko 10 a MCU. Mukalandira chizindikiro cha gawo lathunthu la sensor, kachitidweko kamapeza mtunda wapafupi kudzera mu algorithm ena, ndikuyendetsa buzzer kapena kuwonetsa bwalo kuti akumbutse driver yapafupi ndi Azimuth.
Ntchito yayikulu yosinthira ma radar system ndikuthandizira kuyimitsa magalimoto, tulukani giya kapena kusiya kugwira ntchito pomwe kuthamanga kwa wachibale kumapitilira liwiro (nthawi zambiri 5km / h).
[Time] Akupanga funde amatanthauza phokoso lomveka lomwe limapitilira kuchuluka kwa makutu a anthu (pamwamba pa 20kHz). Ili ndi mawonekedwe a pafupipafupi, kufalikira kolunjika kwa mzere, kukhala ndi chizolowezi chabwino, chosokoneza champhamvu, cholowera champhamvu, pafupifupi 340m / s) ndi zina zambiri. Mafunde akupanga amayenda kudutsa opaque ndipo amatha kulowa pansi pakuya kwa mita. Pamene akupanga amakumana ndi zosayera kapena mawonekedwe, zimatulutsa mafunde, zomwe zingagwiritsidwe ntchito kupezeka kwa kuyamwa kapena kukulirani, ndipo zitha kupangidwa kukhala dongosolo loyambira.
