Kuvamile kakhulu kunalokho ongakucabanga ukuthi ichashazi eliluhlaza okwesibhakabhaka efonini yakho liphawula indawo okuyo, kodwa umcibisholo ukhomba eCuenca uma ubheka enyakatho. Uma lokhu kwenzeka, Ngokuvamile akuyona inkinga ye-GPS, kodwa inkinga ngekhampasi yangaphakathi yocingo., i-magnetometer edumile abayisebenzisayo izinhlelo zokusebenza ezifana ne-Google Maps ukwazi ukuthi ubhekephi.
Uma ubona ukuthi imephu ijikeleza ngendlela exakile, ukuthi indlela ekhonjiswe yifoni ephathekayo ayihambisani neqiniso, noma ukuthi I-Google Maps ithatha isikhathi ukuthola indawo yakho ngendlela efanele.Kungenzeka kakhulu ukuthi ikhampasi ayilungiseki. Izindaba ezinhle ukuthi Ukulungisa ikhampasi ekhomba kabi kulula, kuyashesha, futhi awudingi mathuluzi akhethekile.Vele uhambise ifoni ephathekayo ngendlela ethile futhi wazi amanye amaqhinga ambalwa okuthuthukisa ukunemba.
Yini ngempela eyenziwa yikhampasi yocingo oluphathwayo futhi ihluke kanjani ku-GPS?
Ngaphakathi kwe-smartphone yakho kunezinzwa eziningana ezisebenza ngesikhathi esisodwa ukukhomba indawo okuyo. Eyaziwa kakhulu yi-GPS, okuyiyona ebangela lokhu. ukubala ngokunembile iphuzu eliqondile emephini lapho ukhona kusetshenziswa amasignali esathelayithi, amanethiwekhi e-Wi-Fi aseduze, kanye nemibhoshongo yeselula. Kodwa-ke, i-GPS ayazi ukuthi ubheke kuphi; iyazi kuphela ukuthi ukuphi.
Yilapho ikhampasi yedijithali noma i-magnetometer ingena khona, inzwa encane Ithola amandla kazibuthe oMhlaba bese ihumusha lolo lwazi lube yizinkomba eziyinhloko. (enyakatho, eningizimu, empumalanga, nasentshonalanga). Ngenxa yalokho, i-Google Maps nezinye izinhlelo zokusebenza zemephu zingabonisa ukuqondiswa kwefoni futhi zijikeleze imephu ukuze ifane nesiqondiso osikhombayo.
Uma i-magnetometer isebenza kahle, Umcibisholo oluhlaza okwesibhakabhaka kumephu ukhomba ngqo lapho ubheke khona ngefoni yakho.noma ngabe umile unganyakazi. Kodwa-ke, uma ingasebenzi kahle, uhlelo luchaza kabi i-magnetic north bese lugcina lukukhombisa indlela engalungile, yize i-GPS isakhombisa indawo okuyo ngendlela efanele.
Ngaphezu kwe-magnetometer, ifoni isebenzisa ezinye izinzwa ukuthuthukisa ukuqondiswa (ungazihlola nge izinhlelo zokusebenza zokuxilonga ihadiweAma-accelerometer anesibopho thola ukunyakaza okuqondile kanye nendawo iyonke yedivayisi yeselula (ngokuqondile, ngokuvundlile, ngokulala phansi, njll.), kuyilapho i-gyroscope ilinganisa ukujikeleza okunembile ezindizeni ezintathu zesikhala. Ngokuhlanganisa yonke le datha, uhlelo luthola isithombe esinembile sendlela obamba ngayo idivayisi.
Uma noma iyiphi yalezi zinto inikeza ulwazi oluhlanekezelwe (unga thola amaphutha ezinzwa), noma uma i-magnetometer ithintwa kakhulu ukuphazamiseka, Indiza yangaphakathi yamagnetic ephethwe yisistimu ayisayi kuhambisana neqinisoYilapho ikhampasi "iqala ukuhlanya" bese uhlelo lokusebenza lwemephu lukubeka ubheke ohlangothini olungalungile yize umile unganyakazi.
Kungani ikhampasi yefoni yami ingasebenzi kahle bese iqala ukukhomba ngendlela engafanele?
Akukhona ukuthi ifoni "iyakhohlwa" ukuthi isenyakatho ikuphi ngokuphazima kweso. Okwenzekayo yilokho Ukufundwa kwensimu yamagnetic yoMhlaba kuxutshwa nezinye izinkundla zamagnetic eziseduze. futhi inzwa ayibe isakwazi ukuhlukanisa kahle okungokwaseMhlabeni nalokho okungokwasemvelweni eseduze.
Noma yimuphi umthombo we-magnetism noma ukuphazamiseka kwe-electromagnetic kungathinta ikhampasi: ozibuthe abanamandla, izipikha, ama-motor kagesi, izintambo ezinamandla aphezuluIzakhiwo ezinkulu zensimbi, njll. Ngisho nokubeka ifoni phezu kwendawo yensimbi kungaphazamisa inzwa uma ihlala lapho isikhathi eside ngokwanele.
Ngaphakathi kwefoni uqobo, kunezinto ezidala ukuphazamiseka okuncane. Amasekethe angaphakathi, ibhethri, injini yokudlidliza, noma ngisho nezinye izesekeli zonke zingaba negalelo. dala "umsindo wamagnetic" oxubana nesignali evela ensimini yamagnetic yoMhlabaKumaselula asezingeni eliphansi noma amadala, lokhu kuvame ukuphawuleka kakhulu ngoba izinzwa aziqondile kakhulu futhi azihlukanisiwe kahle.
Esinye isici esivamile ukushintsha kwesimo noma indawo. Uma usuka endaweni evulekile uye egalaji lokupaka elingaphansi komhlaba elinezinsimbi eziningi nxazonke, noma uma usebenzisa ifoni yakho ephathekayo ngaphakathi emotweni, Ikhampasi ingase iqale ukufunda insimu yamagnetic ehlukile kwejwayelekile. futhi kudinga ukulungiswa kabusha.
Izinhlelo zokusebenza eziningi, ikakhulukazi i-Google Maps, zingabona uma ukunemba kwesihloko kuphansi noma kuphakathi. Yingakho ngezinye izikhathi ubona isexwayiso esithi... Ukunemba kwekhampasi kuphansi futhi kufanele ilinganiswe kabusha.Lesi sixwayiso asihlobene nokumbozwa kwedatha noma i-GPS, kodwa nendlela i-magnetometer echaza ngayo insimu yamagnetic.
Icebo elidumile elithi "figure-eight": indlela yokulungisa kabusha ikhampasi yefoni yakho ephathekayo
Indlela eyaziwa kakhulu nephumelela kakhulu yokulungisa ikhampasi uma ikhombe ngendlela engalungile ibizwa ngokuthi "ijika lesishiyagalombili" noma icebo lesishiyagalombiliCishe uke wakubona ku-Google Maps: kukukhombisa umdwebo omncane wefoni yakho ihamba ngesimo se-figure-eight emoyeni.
Ukunyakaza akuhleliwe. Uma ulandela isibalo sesishiyagalombili esikhaleni, Uphoqa i-magnetometer ukuthi iqophe ukufundwa kwensimu yamagnetic kuma-axes amathathu esikhala (X, Y, kanye no-Z) Uhlelo luhlanganisa lolu lwazi nama-accelerometer kanye ne-gyroscope. Lokhu kuvumela ifoni ukuthi ihlukanise kangcono phakathi kolwazi oluhlobene nensimu yamagnetic yoMhlaba kanye nolwazi oluhlobene nokuphazamiseka okuseduze.
Ukuze icebo lisebenze kahle, kungcono ukubamba idivayisi ngokuqinile. Khumbula ukuthi Kwezinye izikhathi, kulula ukuthi ifoni iphume esandleni sakho. Uma ukwenza ngokushesha noma endaweni ecwebezelayo kakhulu. Uma ungaphandle, kungcono ukukubamba ngokuqinile ukuze ugweme noma yikuphi ukwesabisa okungadingekile.
Akuphoqelekile ukulandela iphethini ephelele yesibalo-eight, kodwa kuyasiza uma ukunyakaza kubanzi, kuthambile, futhi... faka ukuzungezisa izihlakala ngezindlela ezahlukeneukuze inzwa "ibone" izinguquko ekuqondeni kuzo zonke izingqimba ezingaba khona. Ngokuvamile, imizuzwana engama-20 noma engama-30 yalo msebenzi yanele ukuthi ikhampasi ibuyele esimweni sayo esijwayelekile.
Uma ukunyakaza sekuqediwe, uhlelo ngokwalo lubala kabusha indiza yangaphakathi yamagnetic futhi, uma konke kuhambe kahle, Umcibisholo wendawo uzokhomba emuva ohlangothini olubheke kulo. Ngisho noma uhlala umile, uzobona ukuthi imephu ihambisana kangcono nendlela yakho nokuthi imiyalelo yokuzulazula inembe kakhulu kusukela ekuqaleni.
Indlela yokulinganisa ikhampasi usebenzisa i-Google Maps isinyathelo ngesinyathelo
Nakuba ungasebenzisa icebo le-figure-eight nganoma yisiphi isikhathi, kulula kakhulu ukusebenzisa i-Google Maps uma usola ukuthi kukhona okungahambi kahle. Uhlelo lokusebenza ngokwalo Kuhlanganisa uhlelo lokulinganisa oluqondiswayo Ikutshela ukuthi wenzeni ngaso sonke isikhathi futhi ikukhombisa izinga lokunemba okufinyelelwe.
Ukuze uqale, vula i-Google Maps bese ulinda ukuthi kuvele ichashazi eliluhlaza okwesibhakabhaka eliphawula indawo yakho. Uma ungaliboni, Thepha isithonjana sendawo ekhoneni elingezansi kwesokudla (indilinga eluhlaza okwesibhakabhaka ngaphakathi kwenye emhlophe) ukuze uhlelo lokusebenza lubeke imephu endaweni yakho yamanje.
Uma ubona ichashazi eliluhlaza okwesibhakabhaka esikrinini, thepha ngqo kulo. Ngokwenza kanjalo, Iphaneli ethi "Indawo yakho" izovela phansi. ngolwazi olwengeziwe kanye nezinketho eziningana ezihlobene nesikhundla sakho.
Kuleyo menyu, uzobona inketho ebizwa ngokuthi "Calibrate". Ukuyithinta kuzovula iwindi elithile ku-Google Maps nge izinga lamanje lokunemba kwekhampasi kanye ne-animation ekukhombisa ukuthi ungayihambisa kanjani ifoni yakho. Ngokuvamile izokucela ukuthi udwebe isithombe sesishiyagalombili emoyeni, njengasesicebweni esikhulume ngaso ngaphambili.
Yenza ukunyakaza njengoba kuboniswe ku-animation, ukuphinde izikhathi eziningana. Njengoba wenza kanjalo, uhlelo lokusebenza luzophinde lubale ukuqondiswa kuze kube yilapho lukwazi ukubonisa isimo "sokunemba okuphezulu" ekhampasini. Ngaleso sikhathi, Thepha ku-"Kwenziwe" bese ukulinganisa kuzoqedwa., ngaphandle kokudinga ukwenza enye into.
Ngemva kwalokhu, imephu kufanele ivame ukujikeleza ngokuhambisana nokunyakaza kwakho, futhi umcibisholo wakho wesikhundla kufanele ukhombe ngendlela efanele ohlangothini obheke kulo. Uma ubona ukuthi amaphutha amakhulu ayaqhubeka, Ungaphinda ukulinganisa noma usuke emithonjeni engaba khona yokuphazamiseka kukazibuthe. ngaphambi kokuzama futhi.
Kufanele ulungise nini ikhampasi yeselula yakho futhi kufanele ukwenze kangaki?
Kumafoni aphathekayo amanje, ikakhulukazi kumamodeli asezingeni eliphakathi kanye nasezingeni eliphezulu, akudingekile ukulinganisa ikhampasi njalo. Izinzwa zithuthuke kakhulu futhi Bayakwazi ukuhlala bezinzile isikhathi eside ngaphandle kokubonisa ukuphambuka okukhulu, uma nje zingaphazanyiswa kakhulu.
Kodwa-ke, kunezimo ezithile lapho kungakuhle khona ukusebenzisa icebo elidumile le-figure-eight noma ukusebenzisa i-Google Maps Assistant. Enye yezinto ezivame kakhulu yile uma ungaphakathi emotweniikakhulukazi uma inesakhiwo esiningi sensimbi noma omazibuthe ezibambini zefoni ephathekayo nokunye okunjalo, okungaphazamisa ukufundwa kwe-magnetometer.
Kungumqondo omuhle futhi ukulinganisa kabusha uma sekuphele isikhathi eside kusukela wagcina ukwenza kanjalo, noma uma uqaphele ukuthi isihloko besilokhu sihluleka kaningi muva nje. Idivayisi ngayinye ihlukile, kodwa Ezindaweni ezinokuphazamiseka okukhulu, ikhampasi iba lula kakhulu ukuyiqondisa.Ngakho-ke, isenzo esincane esisheshayo ngaphambi kokuqala umzila singakusindisa ezindleleni ezingadingekile.
Esinye isibonelo lapho ukulinganisa kuba yinto ebalulekile yilapho usebenzisa ifoni yakho ephathekayo emisebenzini yangaphandle, ukuhamba ngezinyawo, noma ukuzulazula. Kulezi zimo, Ukuba neziqondiso eziqondile kungenza umehluko phakathi kokuhlala endleleni efanele noma ukulahleka. ngokuphambuka ejikeni. Imizuzwana embalwa yokulinganisa ekuqaleni komzila ingakunikeza ukuthula kwengqondo okukhulu.
Ngokuvamile, akudingeki ukhathazeke kakhulu, futhi uhlelo lokusebenza ngokwalo luzokuxwayisa uma luthola ukunemba okuphansi. Uma uthola isaziso, silalele. Ukulinganisa ngaleso sikhathi kuzovimbela ukufundwa okungajwayelekile kanye nokuzungeza kwemephu okungenangqondo. uma nje ubheka isikrini kakhulu ukuze uziqondise.
Ukufundwa okunembile: indlela yokubamba nokusebenzisa idivayisi ukuze kufundwe okunembile
Ngaphezu kokulinganisa uma kudingeka, kubalulekile ukuthi ifoni ikwazi "ukufunda" kahle insimu kazibuthe ngesikhathi sokusetshenziswa okuvamile. Ukuze kufezwe lokhu, kuyalulekwa ukuthi Gcina idivayisi icishe ivundlile uma usebenzisa imodi yekhampasi noma uma uqiniseka kakhulu ngendlela eboniswe yimephu.
Uma utshekisa ifoni yakho kakhulu noma uyijika ngokucijile, uhlelo luzokwazi ukubala ukuma kwayo, kodwa ukufundwa kwayo kungaba nomsindo kancane. Noma nini lapho kungenzeka, Bamba ifoni phansi, njengokungathi uphethe imephu ephepheni.ikakhulukazi uma ufuna ukuhlola ukuthi umcibisholo ukhomba kuphi ngqo.
Kuphinde kusize ukugcina idivayisi kude nezinto zensimbi noma imithombo yamandla kazibuthe anamandla: amawashi amakhulu esihlakaleni, amasongo ensimbi, izipikha eziphathwayo, izintambo zikagesi ezijiyile, noma ngisho nama-safe. Uma "umsindo" omncane okhona ozungeze ifoni, ukufunda kuzoba hlanzekile kakhulu. lokho okwenziwa yi-magnetometer.
Kumadivayisi amaningi akhethekile okuzulazula, njengamawashi ezemidlalo noma amadivayisi e-GPS asezintabeni, kuyanconywa inqubo yokuqala yokulinganisa ngokucophelela Benza lokhu ngokushesha nje lapho ubakhipha ebhokisini noma ngemva kokushintsha ibhethri. Abanye baze bakwazise ngokuzenzakalelayo uma bebona ukuthi ikhampasi idinga ukulungiswa.
Uma kuvela isixwayiso, landela imiyalelo yomenzi, evame ukudinga ukugcina izinga lomshini kanye zungezisa idivayisi kancane kancane ngokwewashi imizuzwana embalwa kuze kube yilapho ikhampasi isebenza kahle. Nakuba ifomethi ihlukile kumaqhinga esibalo-eight, umqondo ufana ncamashi: ukuthola ukufundwa kuzo zonke izingqimba ukuze ubale kabusha indiza yamagnetic.
Ukulungisa ukwehla: umehluko phakathi kwenyakatho yangempela kanye nenyakatho yamagnetic
Ngaphandle kokulinganisa, kukhona omunye umqondo obalulekile lapho kukhulunywa ngamakhampasi: ukwehla. Amamephu ephepha namamephu amaningi e-topographic Zisekelwe enyakatho yendawo noma enyakatho yangempelaokuyisiqondiso esibheke ku-axis yokujikeleza koMhlaba. Kodwa-ke, amakhampasi akhomba enyakatho yamagnetic, etholakala endaweni ehlukile futhi, ngaphezu kwalokho, iyashintsha ngokuhamba kwesikhathi.
I-engeli ephakathi kwenyakatho yamagnetic kanye nenyakatho yangempela endaweni ethile eMhlabeni ibizwa ngokuthi i-declination. Leli nani Ngokuvamile kukhonjiswa kumamephu e-topographic futhi kubuyekezwa njalo Ngoba indawo ye-magnetic north pole iyashintsha unyaka nonyaka. Ukuze uthole ukwehliswa okunembile kakhulu, ungaxhumana nezinhlangano ezisemthethweni noma usebenzise ama-calculator akhethekile ku-inthanethi.
Kwamanye amadivayisi okuzulazula athuthukile kanye nakwezinye izinhlelo zokusebenza, ungafaka lelo nani lokwehla ukuze Ikhampasi ilungisa ngokuzenzakalelayo umehluko phakathi kwala mazwe amabili asenyakatho.Ngale ndlela, lapho ikhampasi ikhomba enyakatho, izohambisana nenyakatho yangempela eboniswe kumephu, okwenza kube lula ukuhamba endaweni eyinkimbinkimbi.
Kodwa-ke, kukhona okuhlukile okubalulekile: amamephu athile okuqondiswa (isib., lawo asetshenziswa emijahweni yokuqondiswa) avame ukuba kudwetshwe ngqo maqondana nenyakatho yamagneticKulezi zimo, umgomo uwukuvala ukulungiswa kokwehla kwe-declination bese usetha lelo nani libe amadigri angu-0, ukuze ikhampasi kanye nemephu "kukhulume ulimi olufanayo".
Kumamenyu akhethekile edivayisi, ungavame ukufinyelela "i-Compass" noma isigaba esifanayo, bese, kusukela lapho, yenza kusebenze noma vala ukulungiswa kokwehla bese ukhetha ukuthi ngabe kusempumalanga (E) noma entshonalanga (W)Ngaphezu kokulungisa inani elithile kusetshenziswa izilawuli ezitholakalayo, ukulungisa kahle le pharamitha kwenza umehluko omkhulu kulabo abadinga ukunemba kokuqondiswa okucophelela kakhulu kunalokho esivame ukukusebenzisa edolobheni.
Ekusetshenzisweni kweselula kwansuku zonke, izinhlelo zokusebenza eziningi sezivele zisingatha lo mehluko ngaphakathi, kodwa ukuqonda umqondo wokwehla kusiza ekwenzeni ukuqonda ukuthi kungani enye inyakatho ingahlali ihambisana ncamashi nenyeikakhulukazi uma usebenza ngamamephu angokoqobo namakhampasi e-analog noma ngamadivayisi okukhuphuka izintaba.
Kwenzekani ngaphakathi uma uhambisa ifoni yakho ngendlela efana nephethini yesishiyagalombili?
Ngaphakathi, icebo le-figure-eight aliyona imilingo; liyizibalo ezisetshenziswa kuma-sensor. I-magnetometer yocingo. Ihlala ilinganisa ubukhulu kanye nesiqondiso sensimu kazibuthe eyizungezile. kuma-axes amathathu esikhala. Lokhu kufundwa okungaphekiwe kuyacutshungulwa futhi kuhlanganiswe nalokho okushiwo yi-accelerometers kanye ne-gyroscope.
Uma ikhampasi iphambuka, uhlelo lugcina "indiza yamagnetic" engasahambisani neqiniso. Ngokwenza ukunyakaza kwesibalo-eight, Udala izikhundla eziningi ezahlukene ngesikhathi esifushaneukuze uhlelo lukwazi ukuqhathanisa lokhu kufundwa okusha nomodeli omdala bese lulahla lezo ezingcoliswe ngokusobala ukuphazamiseka.
Umakhalekhukhwini awubheki nje idatha eyodwa kuphela; ubheka ulwazi oluhlanganisa izinkomba. Uma i-magnetometer isho into eyodwa kodwa Ama-accelerometer kanye ne-gyroscope abonisa ukuqondiswa okungahambisaniI-algorithm ingaphetha ngokuthi lokhu kufundwa akuthembekile futhi ilungise imodeli. Ngokulungiswa okwanele ezindleleni ezahlukene, umphumela wokugcina uba ikhampasi "ehlanzekile" nengaguquguquki.
Yingakho kubalulekile ukuthi ukunyakaza kungagcini nje ekujikeleziseni ifoni endaweni eyodwa. Uma ukujikeleza kuhlukahluka kakhulu, kungcono. Izinhlelo zokuzulazula zesimanje zama-smartphone Bathembele kulolu hlobo lokuhlanganiswa kwezinzwa ukuze banikeze isiqondiso esizinzile ngokwengeziwe.ngisho nasezindaweni zasemadolobheni lapho ukuphazamiseka kuvame kakhulu khona.
Le nhlanganisela yedatha nayo inesibopho sokwenza imephu ikwazi ukulandela indlela ohamba ngayo ngisho noma isignali ye-GPS ingaphelele, njengasemigwaqweni emincane kakhulu noma ezindaweni ezinezakhiwo eziningi ezinde. Ikhampasi kanye nezinzwa ze-inertial zigcwalisa izikhala ezishiywe yi-GPSokuvumela isipiliyoni sokuphequlula esibushelelezi nesingenaziphazamiso.
Uma, naphezu kwakho konke, ubona ukuthi ukuqondiswa kusahluleka, kufanelekile futhi ukuhlola ezinye izici: ukuvala okwesikhashana amacala anama-magnet, ukusuka emithonjeni enamandla kakhulu yamandla adonsela phansi, noma Qala kabusha idivayisi ukuze uphoqe uhlelo lwenzwa ukuthi luqale kusukela ekuqaleni.Ezimweni ezimbi kakhulu, kungaba ukwehluleka kwenzwa ngokomzimba, kodwa ngokuvamile ngokulinganisa okuhle nokunakekela okuthile inkinga izoxazululwa.
Ukwazi kahle la maqhinga amancane okulinganisa nokuqonda indima yekhampasi yedijithali kufoni yakho ephathekayo kukuvumela ukuthi uthole okuningi kuzinhlelo zokusebenza zemephu, imisebenzi yangaphandle, nanoma yisiphi isimo lapho udinga ifoni yakho ukuthi ikutshele ngokunembile hhayi nje ukuthi ukuphi, kodwa nokuthi ukhomba kuphi - kubalulekile lapho ikhampasi yokuqala iqala ukukhomba ohlangothini olungalungile.
