Car Navigation Positioning Control Board
Tsatanetsatane
The car navigation positioning control board ndi chipangizo chotsogola kwambiri komanso cholondola chamagetsi chomwe chimapangidwira makina oyendetsa magalimoto.Bungweli limagwira ntchito yofunika kwambiri pozindikira ndi kutsata malo omwe galimotoyo ili, ndikuonetsetsa kuti woyendetsayo aziyenda bwino komanso kuti aziwongolera.Bolodi yoyang'anira malo imaphatikiza ukadaulo wa GPS (Global Positioning System) ndi masensa ena oyimilira monga GLONASS (Global Navigation Satellite System) ndi Galileo kuti apereke chidziwitso chodalirika komanso cholondola.Makina opangidwa ndi setilaitiwa amagwira ntchito limodzi kuti awerengere kutalika kwa galimoto, kutalika kwake ndi kutalika kwake, zomwe zimathandiza kuti zidziwitso zolondola, zenizeni zenizeni.Gulu lowongolera lili ndi microcontroller yamphamvu kapena system-on-chip (SoC) kuti igwiritse ntchito bwino zomwe zalandilidwa ndikuwerengera malo agalimoto.
Kukonza uku kumaphatikizapo ma aligorivimu ovuta komanso mawerengedwe kuti adziwe komwe galimoto ili, mutu ndi zina zofunika kuyenda.Bungweli limagwirizanitsa njira zosiyanasiyana zoyankhulirana monga CAN (Controller Area Network), USB ndi UART (Universal Asynchronous Receiver-Transmitter).Mawonekedwe awa amalola kusakanikirana kosasunthika ndi machitidwe ena agalimoto, kuphatikiza mayunitsi owonetsera pa bolodi, makina omvera ndi zowongolera zowongolera.Kuyankhulana kumathandiza gulu lowongolera kuti lipereke chitsogozo chowoneka ndi chomveka kwa dalaivala mu nthawi yeniyeni.Kuphatikiza apo, bolodi loyang'anira malo lili ndi zida zomangira zokumbukira ndi zosungiramo zosungirako deta yamapu ndi zidziwitso zina zofunika.Izi zimathandizira kubweza mwachangu kwa data yamapu ndikukonza moyenera deta yoyika nthawi yeniyeni, kuwonetsetsa kuti kuyenda kosavuta komanso kosasokoneza.Gulu lowongolera limaphatikizanso zolowetsa zingapo zama sensor monga accelerometers, gyroscopes, ndi magnetometers.
Masensa amenewa amathandiza kulondola kwa deta ya malo polipira zinthu monga kuyenda kwa galimoto, momwe msewu ulili komanso kusokoneza maginito.Kuonetsetsa kuti magwiridwe antchito ndi odalirika, gulu lowongolera limapangidwa ndi ntchito zamphamvu zowongolera mphamvu ndi njira zotetezera.Izi zimathandizira kusinthasintha kwamphamvu, kusintha kwa kutentha ndi kusokonezedwa ndi ma elekitiroma, kuwonetsetsa kuti ikugwira ntchito mosasamala ngakhale pamavuto.Firmware ndi mapulogalamu a bolodi zitha kusinthidwa mosavuta ndikusinthidwa kuti ziwonjezeke mtsogolo.Izi zimatsimikizira kuti ogwiritsa ntchito angapindule ndi zomwe zachitika posachedwa komanso kupita patsogolo kwaukadaulo popanda kusintha gulu lonse lowongolera.Mwachidule, gulu lowongolera ma navigation poyimitsa magalimoto ndi gawo lotsogola komanso lofunika kwambiri pamakina amakono oyendetsa magalimoto.Kupyolera mu mawerengedwe olondola a malo, kukonza bwino, ndi kugwirizanitsa mosasunthika ndi makina ena agalimoto, bolodi imathandiza madalaivala kuyenda motetezeka ndi molondola kupita komwe akufuna.Kudalirika kwake, scalability ndi kukweza kumapangitsa kukhala gawo lofunikira pakukula kwamakampani amagalimoto.
