Mota Navigation Positioning Control Board

Tsanangudzo Pfupi

GPS, kana Global Positioning System, inzira yesatellite yekufambisa yakagadziriswa nehurumende yeUnited States uye inoshanda pasi rose.Zita rinozivikanwa remasystem aya iGlobal Navigation Satellite System kana kuti GNSS, GPS ichiva iyo inonyanya kushandiswa GNSS system.Pakutanga GPS yaingoshandiswa pakufamba kwemauto, asi iye zvino chero munhu ane GPS inogamuchira anogona kuunganidza masaini kubva kumasatelliti eGPS oshandisa sisitimu.

GPS ine zvikamu zvitatu:

satellite.Chero nguva ipi zvayo, kune masetellite eGPS anosvika makumi matatu anotenderera muchadenga, imwe neimwe inosvika makiromita 20 000 pamusoro pePasi.

control station.Zviteshi zvekudzora zvakapararira pasirese kuti vatarise uye vadzore masatelliti, nechinangwa chikuru chekuchengeta sisitimu ichimhanya uye kuona chokwadi chezviratidzo zvekutepfenyura zveGPS.

GPS inogamuchira.GPS inogashira inowanikwa munharembozha, makomputa, mota, zvikepe, uye zvimwe zvigadziriso zvakawanda, uye kana pasina zvipingamupinyi zvakaita sezvivakwa zvirefu zvakakukomberedza uye mamiriro ekunze akanaka, GPS yako inogamuchira inofanirwa kuona kanenge mana GPS satellite panguva. zvisinei kuti uripi.

Iyo mota navigation positioning control board ndeye yepamusoro-soro uye chaiyo yemagetsi control unit yakanyatsogadzirirwa mota navigation system.Bhodhi rinoita basa rakakosha mukuona uye kuronda nzvimbo yemotokari, kuve nechokwadi chekufamba chaiko uye kutungamira kumutyairi.Iyo yekumisikidza bhodhi inosanganisa tekinoroji yeGPS (Global Positioning System) nemamwe masensa ekumisikidza akadai seGLONASS (Global Navigation Satellite System) uye Galileo kuti ipe ruzivo rwakavimbika uye rwakakwana rwekumisikidza.Aya masisitimu esatellite anoshanda pamwechete kuverenga latitude, longitude uye urefu hwemotokari, ichigonesa data yekufamba, chaiyo-nguva.Iyo control board inoshongedzerwa ine ine simba microcontroller kana system-on-chip (SoC) kunyatso gadzirisa iyo yakagamuchirwa yekumisikidza data uye kuverenga nzvimbo yemotokari.

Car navigation positioning control board

Kugadziriswa uku kunosanganisira ma algorithms akaomarara uye maverengero ekuona mamiriro emotokari ikozvino, musoro uye mamwe ekutanga maparamita ekufambisa.Bhodhi rinobatanidza nzvimbo dzakasiyana dzekutaurirana dzakadai seCAN (Controller Area Network), USB uye UART (Universal Asynchronous Receiver-Transmitter).Aya mainterface anobvumira kubatanidzwa kusina musono nemamwe masisitimu emotokari, anosanganisira ari pa-bhodhi anoratidza mayunitsi, maodhiyo masisitimu uye zvidhiraivho.Mamiriro ekutaurirana anogonesa iyo control panel kuti ipe inooneka uye inonzwika kutungamira kumutyairi munguva chaiyo.Uye zvakare, iyo Positioning control board ine yakavakirwa-mukati ndangariro uye kuchengetedza mabasa ekuchengetedza mepu data uye rumwe ruzivo rwakakodzera.Izvi zvinogonesa kudzoreredza nekukurumidza kwemepu data uye kunyatsogadziriswa kweiyo-chaiyo-nguva yekumisikidza data, kuve nechokwadi chekufamba kwakatsetseka uye kusingapindiki.Iyo control board inosanganisira akati wandei ma sensor ekuisa akadai se accelerometers, gyroscopes, uye magnetometers.

Aya masensa anobatsira kuvandudza kurongeka kwedata renzvimbo nekubhadhara zvinhu zvakaita sekufamba kwemotokari, mamiriro emigwagwa uye kukanganiswa kwemagineti.Kuti ive nechokwadi chekushanda kwakakwana uye kuvimbika, bhodhi rekutonga rakagadzirwa nemasimba ane simba ekugadzirisa mabasa uye nzira dzekudzivirira.Izvi zvinoibvumira kubata kushanduka kwesimba, shanduko yetembiricha uye kukanganiswa kwemagetsi, kuve nechokwadi chekuita zvisina musono kunyangwe pasi pemamiriro ezvinhu akaoma.Iyo bhodhi's firmware uye software inogona kuvandudzwa uye kukwidziridzwa kune ramangwana rekusimudzira nekuvandudza.Izvi zvinoita kuti vashandisi vabatsirwe kubva kune ichangoburwa maficha uye kufambira mberi kwetekinoroji pasina kutsiva iyo yese control panel.Kupfupisa, iyo mota yekufambisa chinzvimbo chekudzora pani chikamu chepamberi uye chakakosha chikamu chemazuva ano chekufambisa mota.Kuburikidza nemaverengero chaiwo echinzvimbo, kugadzirisa kwakanaka, uye kusanganisa kusina musono nemamwe masisitimu emotokari, bhodhi rinogonesa vatyairi kufamba zvakachengetedzeka uye nemazvo kwavanoda kuenda.Kuvimbika kwayo, scalability uye kukwidziridzwa kunoita kuti ive chikamu chakakosha cheindasitiri yemotokari iri kukura.
