Ku-Habré bavame ukubhala mayelana nokuthutha ngogesi. Futhi mayelana namabhayisikili. Futhi mayelana ne-AI. I-Cloud4Y inqume ukuhlanganisa lezi zihloko ezintathu ngokukhuluma ngebhayisikili likagesi “elihlakaniphile” elihlala liku-inthanethi. Sizokhuluma ngemodeli yeGreyp G6.
Ukwenza kube mnandi kuwe, sihlukanise isihloko sibe izingxenye ezimbili. Esokuqala sizinikele ohlelweni lokudala idivayisi, iplathifomu kanye nezivumelwano zokuxhumana. Okwesibili ukucaciswa kwezobuchwepheshe, incazelo ye-hardware namakhono ebhayisikili.
Ingxenye yokuqala, i-backend
I-Greyp Bikes ingumkhiqizi waseCroatia wamabhayisikili kagesi aphambili, aphethwe umkhiqizi wasendaweni wasendaweni we-supercar u-Rimac. Inkampani idala amabhayisikili athakazelisa ngempela. Bheka nje imodeli yangaphambilini, i-dual-suspension G12S. Kwakuyinto ethile phakathi kwebhayisikili kagesi nesithuthuthu sikagesi, njengoba idivayisi ingasheshisa ukuya ku-70 km / h, yayinemoto enamandla futhi igijima amakhilomitha angu-120 ngenkokhelo eyodwa.
I-G6 iphenduke yaba yinhle kakhulu futhi ingekho emgwaqeni, kodwa isici sayo esiyinhloko “ukuxhumana.” uthathe isinyathelo esibalulekile ekuthuthukisweni kwe-IoT ngokunikeza ibhayisikili elihlala “liku-inthanethi”. Kodwa ake siqale sikhulume ngokuthi ibhayisikili kagesi "ehlakaniphile" yadalwa kanjani ekuqaleni.
Ukuzalwa komqondo
Inani elikhulu lamadivayisi ahlukene axhumeka ku-inthanethi. Kungani amabhayisikili emabi kakhulu? Yileyo ndlela abakwaGreyp Bikes abaqhamuke ngayo nombono owaba yi-G6. Nganoma yisiphi isikhathi, leli bhayisikili lixhunywe ku- . Umsebenzisi weselula uhlinzeka ngoxhumano, futhi i-eSIM ithungelwa ngqo ebhayisikilini. Futhi lokhu kuvula amathuba amaningi anentshisekelo kubo bobabili abasubathi nabathandi bamabhayisikili abajwayelekile.
Platform
Lapho udala inkundla yomkhiqizo omusha, ama-nuances amaningi adinga ukucatshangelwa. Ngakho-ke, ukukhetha isiteji samafu sokusingatha nokusebenzisa zonke izinsizakalo ezidingekayo ngebhayisikili kagesi yesimanje kwakuyindaba ebaluleke kakhulu. Inkampani ikhethe i-Amazon Web Services (AWS). Lokhu bekungenxa yokuthi abakwaGreyp Bikes base benolwazi ngale sevisi. Ngokwengxenye - ngenxa yokuthandwa kwayo, ukusatshalaliswa okubanzi phakathi konjiniyela emhlabeni jikelele kanye nesimo sengqondo esihle ngeJava / JVM (yebo, asetshenziswa ngokuqhubekayo kuma-Greyp Bikes).
I-AWS yayinomthengisi omuhle we-IoT MQTT (I-Cloud4Y ibhale ngamaphrothokholi ), ilungele ukushintshaniswa kwedatha okulula ngebhayisikili lakho. Yiqiniso, kwakudingeka ngandlela-thile ukusungula uxhumano nesicelo se-smartphone. Kube nemizamo yokwenza lokhu ngokwabo kusetshenziswa ama-Websockets, kodwa ngokuhamba kwesikhathi inkampani yanquma ukungalisunguli kabusha isondo futhi yashintshela ku-platform ye-Google Firebase, esetshenziswa kakhulu ngabathuthukisi beselula. Kusukela ekuqaleni kwentuthuko, i-architecture yesistimu iye yaba nentuthuko nezinguquko eziningi. Lokhu cishe kubukeka kanjani manje:
Isitaki sobuchwepheshe
Ukuqaliswa
Inkampani inikeze izindlela ezimbili zokungena ohlelweni. Ngayinye yazo isetshenziswa ngokwehlukana, ngobuchwepheshe obuhlukene bokusetshenziswa kwayo.
Kusukela ngebhayisikili kuya ku-smartphone
Into yokuqala okufanele icatshangelwe lapho udala indawo yokungena yesistimu ukuthi iyiphi iphrothokholi yokuxhumana okufanele isetshenziswe. Njengoba sekushiwo, inkampani ikhethe i-MQTT ngenxa yemvelo yayo engasindi. Iphrothokholi yinhle ngokomsebenzi, isebenza kahle ngoxhumo olungathembeki, futhi yonga amandla ebhethri, abaluleke kakhulu ebhayisikilini likagesi leGreyp.
Umthengisi we-MQTT osetshenzisiwe uyadingeka ukulayisha yonke idatha evela ebhayisikilini. Ngaphakathi kwenethiwekhi ye-AWS kukhona i-Lambda, efunda idatha kanambambili enikezwe umthengisi we-MQTT, iyihlukanise, bese iyiletha ku-Apache Kafka ukuze iqhubeke nokusebenza.
I-Apache Kafka iwumgogodla wohlelo. Yonke idatha kufanele idlule kuyo ukuze ifinyelele lapho iya khona ekugcineni. Njengamanje, umgogodla wesistimu unama-ejenti amaningana. Okubaluleke kakhulu yileyo eqoqa idatha bese iyidlulisela ku-InfluxDB isitoreji esibandayo. Enye idlulisela idatha kusizindalwazi se-Firebase Realtime, iyenze itholakale ezinhlelweni zokusebenza ze-smartphone. Yilapho i-Apache Kafka ingena khona ngempela - isitoreji esibandayo (i-InfluxDB) igcina yonke idatha evela ebhayisikilini futhi i-Firebase ingathola ulwazi lwakamuva (isb. amamethrikhi esikhathi sangempela - isivinini samanje).
I-Kafka ikuvumela ukuthi uthole imilayezo ngesivinini esihlukile futhi uyilethe cishe ngokushesha ku-Firebase (ukuze iboniswe kuhlelo lokusebenza ku-smartphone) futhi ekugcineni uyidlulisele ku-InfluxDB (yokuhlaziywa kwedatha, izibalo, ukuqapha).
Ukusebenzisa i-Kafka futhi kukuvumela ukuthi ukale uvundlile njengoba umthwalo ukhuphuka, futhi uxhume amanye ama-ejenti angacubungula idatha engenayo ngejubane lawo kanye nesimo sawo sokusebenzisa (njengomjaho phakathi kweqembu lamabhayisikili). Okusho ukuthi, ikhambi livumela abagibeli bamabhayisikili ukuthi baqhudelane bodwa ezicini ezihlukahlukene. Isibonelo, isivinini esiphezulu, ukugxuma okuphezulu, ukusebenza okuphezulu, njll.
Wonke amasevisi (abizwa ngokuthi "GVC" - Greyp Vehicle Cloud) asetshenziswa ngokuyinhloko ku-Spring Boot ne-Java, nakuba ezinye izilimi zisetshenziswa. Isakhiwo ngasinye sipakishwe kusithombe se-Docker esisingathwe endaweni yokugcina ye-ECR, eyethulwe futhi yahlelwa yi-Amazon ECS. Nakuba i-NoSQL ilula futhi idumile ezimweni eziningi, i-Firebase ayikwazi njalo ukuhlangabezana nazo zonke izidingo zikaGreyp, ngakho-ke inkampani isebenzisa i-MySQL (ku-RDS) ngemibuzo ye-ad-hoc (i-Firebase isebenzisa isihlahla se-JSON, esisebenza kahle kakhulu ezinye izimo) nokugcina idatha ethile. Esinye isitoreji esisetshenzisiwe yi-Amazon S3, eqinisekisa ukuphepha kwedatha eqoqiwe.
Kusukela ku-smartphone kuya ebhayisikili
Njengoba sesishilo, ukuxhumana nama-smartphones kusungulwa nge-Firebase. Ipulatifomu isetshenziselwa ukuqinisekisa abasebenzisi bohlelo lokusebenza kanye nocezu lwabo lwesizindalwazi ngesikhathi sangempela. Eqinisweni, i-Firebase iyinhlanganisela yezinto ezimbili: eyodwa iyisizindalwazi sokugcinwa kwedatha okuqhubekayo, kanti enye eyokuletha idatha yesikhathi sangempela kuma-smartphones ngoxhumano lweWebsocket. Inketho ekahle yalolu hlobo lokuxhumana ukukhipha imiyalo ebhayisikilini lapho amadivaysi engasondeli komunye nomunye (akukho uxhumano lwe-BT/Wi-Fi olutholakalayo).
Kulokhu, abakwaGreyp bazenzele eyabo indlela yokucubungula imiyalo, ethola imilayezo evela ku-smartphone ngokusebenzisa isizindalwazi esikumodi yesikhathi sangempela. Lo mshini uyingxenye yezinsizakalo zohlelo lokusebenza eziyinhloko (i-GVC), umsebenzi wazo ukuhumusha imiyalo ye-smartphone ibe imilayezo ye-MQTT edluliselwa ebhayisikilini ngomthengisi we-IoT. Uma ibhayisikili lithola umyalo, liyawucubungula, lenze isenzo esifanele, bese libuyisela impendulo ku-Firebase (i-smartphone).
Ukuqapha
Ukulawula ipharamitha
Cishe wonke umthuthukisi we-backend uthanda ukulala ebusuku ngaphandle kokuhlola amaseva njalo ngemizuzu eyi-10. Lokhu kusho ukuthi kuyadingeka ukusebenzisa izixazululo zokuqapha nezixwayiso ezizenzakalelayo ohlelweni. Lo mthetho uyasebenza naku-Greyp cycling ecosystem. Kukhona futhi ochwepheshe bokulala kahle ebusuku, ngakho inkampani isebenzisa izixazululo ezimbili zamafu: I-Amazon CloudWatch ne-jmxtrans.
I-CloudWatch iyisevisi yokuqapha nokubonakala eqoqa idatha yokuqapha neyokusebenza ngendlela yamalogi, amamethrikhi, nemicimbi, ikusiza ukuthi uthole ukubuka okuhlangene kwezinhlelo zokusebenza ze-AWS, amasevisi, nezisetshenziswa ezisebenza kuplathifomu ye-AWS nasezindaweni ezikhona. Nge-CloudWatch, ungathola kalula impatho exakile endaweni yakho, usethe izexwayiso, udale ukubonwa okuvamile kwamalogi namamethrikhi, wenze izenzo ezizenzakalelayo, uxazulule izinkinga, futhi uthole imininingwane engenziwa egcina izinhlelo zakho zokusebenza zisebenza kahle.
I-CloudWatch iqoqa amamethrikhi omsebenzisi futhi iwalethe kudeshibhodi. Lapho, ihlanganiswa nedatha evela kwezinye izinsiza eziphethwe yi-Amazon. I-JVM ithola amamethrikhi ngephoyinti lokugcina le-JMX isebenzisa "isixhumi" esibizwa ngokuthi i-jmxtrans (futhi isingathwe njengesiqukathi se-Docker ngaphakathi kwe-ECS).
Ingxenye yesibili, izici
Ngakho hlobo luni lwebhayisikili likagesi ogcine usunalo? Ibhayisikili lasentabeni likagesi iGreyp G6 ifakwe ibhethri ye-lithium-ion engu-36V, 700 Wh enikwa amandla amaseli e-LG. Esikhundleni sokufihla ibhethri njengoba kwenza abakhiqizi abaningi be-e-bike, u-Greyp ubeke ibhethri elikhiphekayo phakathi nendawo yohlaka. I-G6 ifakwe injini ye-MPF enamandla alinganiselwe angu-250 W (futhi kukhona inketho engu-450 W).
I-Greyp G6 ibhayisikili lasezintabeni elihlanganisa ukumiswa kwe-Rockhox okungemuva, okunamathiselwe eduze kweshubhu eliphezulu futhi okushiya indawo eningi yebhethri elikhiphekayo phakathi kwamadolo omgibeli. Uhlaka luyisitayela se-enduro futhi lunikeza u-150mm wokuhamba ngenxa yokumiswa. Ikhebula nemigqa yebhuleki ihanjiswa ngaphakathi kohlaka. Lokhu kuqinisekisa ukubukeka kobuhle futhi kunciphisa ubungozi bokubanjwa emagatsheni.
Uhlaka lwe-carbon fiber engu-100% lwathuthukiswa ngokukhethekile ngu-Greyp esebenzisa ulwazi oluzuzwe ngesikhathi kudalwa i-Concept One electric hypercar.
I-electronics suite ku-Greyp G6 ilawulwa imojula ye-central intelligence (CIM) esiqwini. Ihlanganisa i-color display, i-WiFi, i-Bluetooth, i-4G yokuxhumana, i-gyroscope, isixhumi se-USB C, ikhamera ebheke phambili, kanye nesixhumi esibonakalayo esinekhamera engaphansi kwesihlalo sangemuva. Ngendlela, ikhamera yangemuva . Amakhamera ane-engeli ebanzi (1080p 30 fps) aklanyelwe ukuthwebula ividiyo ngenkathi ehamba.
Izibonelo zesithombe
Inkampani inaka ngokukhethekile isisombululo se-eSTEM.
“IGreyp eSTEM iyimojula ehlakaniphile emaphakathi yebhayisikili elawula amakhamera amabili (angaphambili nangemuva), eqapha ukushaya kwenhliziyo yomgibeli, ine-gyroscope eyakhelwe ngaphakathi, i-navigation system ne-eSIM, evumela ukuthi ixhunywe noma nini. Uhlelo lwe-e-bike lusebenzisa i-smartphone njengesixhumi esibonakalayo somsebenzisi futhi uhlelo lokusebenza lweselula ludala ulwazi lomsebenzisi oluhlukile olunezinketho ezintsha ezihlukahlukene njengokushintshwa kwebhayisikili okude, ukuthwebula izithombe, umbhalo oya ebhayisikilini kanye nokukhawulela amandla.”
Kunenkinobho ekhethekile ethi "Yabelana" kuzibambo zebhayisikili. Uma okuthile okuthakazelisayo noma okujabulisayo kwenzeka phakathi nohambo lwakho, ungacindezela inkinobho futhi ulondoloze ngokuzenzakalelayo imizuzwana yokugcina engu-15-30 yevidiyo bese uyilayisha ku-akhawunti yenkundla yezokuxhumana yomgibeli wamabhayisikili. Idatha eyengeziwe ingase ibekwe phezulu kuvidiyo. Isibonelo, ukusetshenziswa kwamandla ebhayisikili, isivinini, isikhathi sokuhamba, njll.
Ngefoni efakwe ebhayisikilini kumodi yedeshibhodi, i-Greyp G6 inganikeza ingcebo yolwazi ngale kokubonisa isivinini sakho samanje noma ileveli yebhethri. Ngakho-ke, umgibeli webhayisikili angakhetha noma yiliphi iphuzu kumephu (isibonelo, igquma eliphakeme), futhi ikhompuyutha izobala ukuthi ukushajwa kwebhethri kwanele yini ukufinyelela phezulu. Noma izobala iphuzu lokungabuyi, uma ngokungazelelwe ungafuni ukunyathela endleleni ebuyayo. Nakuba ama-pedals angaphendulwa kalula. Umkhiqizi uqinisekisa ukuthi ibhayisikili alinzima (nakuba kuye ngokuthi ulibheka kanjani, isisindo salo singama-25 kg).
IGreyp G6 iyakwazi ukuphakamisa
I-Greyp G6 inesistimu yokulwa nobugebengu efana ne kusuka ku-Tesla. Okusho ukuthi, uma uthinta ibhayisikili elimile, izokwazisa umnikazi futhi imnike ukufinyelela kukhamera ukuze athole ukuthi ubani ozungeza ibhayisikili likagesi. Umshayeli angabe esekhetha ukukhubaza ibhayisikili ekude ukuze avimbele isigebengu ekushayeleni kude. Futhi uma kubhekwa ukuthi lezi zinhlelo bezilokhu zithuthukiswa eGreyp iminyaka, kungenzeka ukuthi baqhamuke nalolu hlelo ngaphambi kokuthi uTesla alusebenzise.
Kunamamodeli amaningana alolu chungechunge oluthengiswayo: G6.1, G6.2, G6.3. I-G6.1 igijima ifinyelele ku-25 km/h (15,5 mph) futhi ibiza u-€6. I-G499 inejubane eliphezulu elingu-6.3 km/h (45 mph) futhi ibiza u-€28. Yini ehlukile ngemodeli ye-G7 akucaci, kodwa ibiza ama-euro angu-499.
