Ibhodi Lokulawula Ukuma Kwezimoto

Ibhodi Lokulawula Indawo Yokuhamba Kwemoto Elifakiwe Isithombe

Incazelo emfushane:

I-GPS, noma i-Global Positioning System, iwuhlelo lokuzulazula ngesathelayithi olwakhiwe uhulumeni wase-United States futhi lusetshenziswa emhlabeni wonke.Igama elivamile lalezi zinhlelo i-Global Navigation Satellite System noma i-GNSS, ne-GPS iwuhlelo lwe-GNSS olusetshenziswa kakhulu.Ekuqaleni i-GPS yayisetshenziselwa ukuhamba kwezempi kuphela, kodwa manje noma ubani onesamukeli se-GPS angaqoqa amasignali kumasathelayithi e-GPS futhi asebenzise uhlelo.

I-GPS inezingxenye ezintathu:

isathelayithi.Nganoma yisiphi isikhathi, kunamasathelayithi e-GPS angaba ngu-30 azungeza emkhathini, ngalinye liqhele ngamakhilomitha angaba ngu-20,000 ngaphezu komhlaba.

isiteshi sokulawula.Iziteshi zokulawula zihlakazeke emhlabeni wonke ukuze ziqaphe futhi zilawule amasathelayithi, ngenhloso enkulu yokugcina uhlelo lusebenza kanye nokuqinisekisa ukunemba kwezimpawu zokusakaza ze-GPS.

Isamukeli se-GPS.Izamukeli ze-GPS zitholakala kumaselula, amakhompuyutha, ezimotweni, ezikebheni nakwamanye amadivaysi amaningi, futhi uma zingekho izithiyo ezifana nezakhiwo ezinde ezikuzungezile nesimo sezulu sisihle, umamukeli wakho we-GPS kufanele abone okungenani amasathelayithi e-GPS amane ngesikhathi. kungakhathaliseki ukuthi ukuphi.

Ibhodi lokulawula ukuzulazula kwemoto liyiyunithi yokulawula ye-elekthronikhi ethuthuke kakhulu futhi enembile yakhelwe ngokukhethekile amasistimu okuzulazula kwemoto.Ibhodi lidlala indima ebalulekile ekunqumeni ngokunembile nasekulandeleni indawo yemoto, liqinisekisa ukuzulazula okunembayo kanye nesiqondiso somshayeli.Ibhodi lokulawula ukuma lihlanganisa ubuchwepheshe be-GPS (Global Positioning System) nezinye izinzwa zokubeka indawo njenge-GLONASS (Global Navigation Satellite System) kanye ne-Galileo ukuze kunikeze ulwazi oluthembekile nolunembile lokuma.Lawa masistimu asekelwe kwisathelayithi asebenza ndawonye ukuze abale i-latitude yemoto, i-longitude nokuphakama, evumela idatha enembile, yesikhathi sangempela sokuzulazula.Ibhodi lokulawula lifakwe i-microcontroller enamandla noma i-system-on-chip (SoC) ukuze icubungule kahle idatha yokuma eyamukelwe futhi ibale indawo yemoto.

Lokhu kucubungula kuhlanganisa ama-algorithms ayinkimbinkimbi nezibalo ukuze kutholwe indawo yamanje yemoto, isihloko kanye nezinye izinhlaka zokuzulazula eziyisisekelo.Ibhodi lihlanganisa ukuxhumana okuhlukahlukene okufana ne-CAN (Inethiwekhi Yendawo Yokulawula), i-USB ne-UART (I-Universal Asynchronous Receiver-Transmitter).Lezi zindawo zokusebenzelana zivumela ukuhlanganiswa okungenamthungo namanye amasistimu emoto, okuhlanganisa amayunithi okuboniswa ebhodini, amasistimu omsindo nezilawuli zokuqondisa.Izici zokuxhumana zinika amandla iphaneli yokulawula ukunikeza isiqondiso esibonakalayo nesizwakalayo kumshayeli ngesikhathi sangempela.Ngaphezu kwalokho, ibhodi lokulawula ukuma lifakwe inkumbulo eyakhelwe ngaphakathi nemisebenzi yokugcina yokugcina idatha yemephu nolunye ulwazi olufanele.Lokhu kuvumela ukubuyiswa okusheshayo kwedatha yemephu kanye nokucutshungulwa okuphumelelayo kwedatha yendawo yangempela, okuqinisekisa ukuzizwisa kokuzulazula okushelelayo nokungaphazamiseki.Ibhodi lokulawula liphinde lifake okokufaka kwenzwa okuningana okufana nama-accelerometer, ama-gyroscopes, nama-magnetometers.

Lezi zinzwa zisiza ukuthuthukisa ukunemba kwedatha yendawo ngokunxephezela izici ezifana nokunyakaza kwemoto, izimo zomgwaqo kanye nokuphazanyiswa kazibuthe.Ukuqinisekisa ukusebenza okuphelele nokuthembeka, ibhodi lokulawula liklanywe ngemisebenzi enamandla yokuphatha amandla kanye nezindlela zokuvikela.Lokhu kuyivumela ukuthi ibhekane nokuguquguquka kwamandla, ukushintsha kwezinga lokushisa kanye nokuphazamiseka kazibuthe kagesi, iqinisekise ukusebenza okungenazihibe ngisho nangaphansi kwezimo eziyinselele.I-firmware yebhodi nesofthiwe ingabuyekezwa kalula futhi ithuthukiswe ukuze kuthuthukiswe futhi kuthuthukiswe esikhathini esizayo.Lokhu kuqinisekisa ukuthi abasebenzisi bangazuza kuzici zakamuva zokuzulazula kanye nentuthuko yezobuchwepheshe ngaphandle kokushintsha iphaneli yokulawula.Ukufingqa, iphaneli yokulawula ukuma kwemoto iyingxenye ethuthukisiwe nebalulekile yohlelo lwesimanje lokuzulazula kwezimoto.Ngezibalo ezinembile zendawo, ukucubungula okuphumelelayo, nokuhlanganiswa okungenamthungo namanye amasistimu ezimoto, ibhodi lenza abashayeli bakwazi ukuzulazula ngokuphepha nangokunembile endaweni abayifunayo.Ukuthembeka kwayo, ukukala nokuthuthuka kwayo kuyenza ibe yingxenye ebalulekile yemboni yezimoto ekhulayo.
