I-Case study: I-GPS ye-Cowin Antenna ye-GPS/Beidou+GSM edityanisiweyo ye-eriyali ephindwe kabini inceda ukhathalelo lwezonyango oludityanisiweyo lufezekise indawo echanekileyo kunye neteknoloji ye-IoT.
Imvelaphi yomthengi:
I-Shanghai Bangbang Intelligent Robot ijolise ekuncedeni abantu abakhubazekileyo babuyele kubomi obuqhelekileyo.Yinkampani yanamhlanje yobugcisa obuphezulu edibanisa uphando oluzimeleyo kunye nophuhliso, imveliso kunye nokuthengiswa kweemveliso ezincedisayo ezikrelekrele.IBangbang Intelligent Robot izibophelele ekuziseni ubomi obusempilweni ngobuchwephesha obukrelekrele, ngokuqhubekayo isakha izisombululo ezikrelekrele kukhathalelo lwempilo lwexesha elizayo, kunye nokudala uphawu lwesizwe oluhlonitshwayo kwicandelo lokunceda abantu abadala nabakhubazekileyo kwihlabathi jikelele.
Imfuneko yokusebenza kwe-antenna:
I-GPS+Beidou+GSM idityaniswe kwi-casing enye, kwaye ukuchaneka kokumisa kungaphakathi kwe-10M.
Umceli mngeni:
Kwabakhubazekileyo, ukubekwa kweliso ngexesha lokwenyani kwangexesha kudlala indima ebalulekileyo.Ukuthatha umntu okhubazekileyo njengomzekelo, ukuchaneka kokumisa akwanele ukwenza ukuba abasebenzi bezonyango bachithe ixesha elide befuna, kwaye unxibelelwano olungazinzanga alukwazi ukuvumela abakhubazekileyo ukuba baqalise i-SOS ngokukhawuleza.uncedo, oluye lwabonakala lungumcelimngeni wobugcisa ukuphuhlisa.Ukuguqulwa kwedijithali kunye nokubeka iliso kwe-24 / 7 kwenza izigqibo ezinolwazi malunga nempilo, umsebenzi kunye nokunyamekela abantu abakhubazekileyo, ekugqibeleni baphucula impilo yabo kunye nomgangatho wobomi.
Inkcazo yengxaki:
Umthengi unokubonelela ngendawo yokubeka i-antenna ngobude be-50 * ububanzi be-40MM.Ngelo xesha, i-antenna yokubeka kunye ne-antenna ye-GSM kufuneka ifakwe kule ndawo.Isithuba esincinci sithetha ukuba ii-eriyali ziyaphazamisana ngaphambili.Injineli idlala indima ebaluleke kakhulu kwiziphumo zolungiso lokuzihlukanisa.
Isisombululo:
1. I-Bangbang Intelligent iyazi ukuba i-antenna ye-GPS ibaluleke kakhulu ukufezekisa ukuchaneka ngaphakathi kwe-10M.Emva kokukhangela iimveliso ezahlukeneyo ze-eriyali, ekugqibeleni yakhetha ukusebenzisana neCowin Antenna.
2. Eyona mfuno ingundoqo kukuba isisombululo se-eriyali ye-eriyali ye-cowin singasebenzisa ibhodi yesekethe njengenqwelo-moya ephantsi ukuthintela ukuphazamiseka kwezinye iisignali zamaza onomathotholo, ngaloo ndlela kuthintela umonakalo wokuchaneka kweGPS.
3. Ii-amplifiers ezimbini ze-LNA kunye nezihlungi zangaphambili ze-SAW ziqulunqwe kwi-chip ye-ceramic ye-18 * 18MM, eyanciphisa kakhulu ingxolo ye-band-of-band.I-antenna eyenziwe nge-bipolar amplifier yenza inzuzo yayo esebenzayo ibe phezulu njenge-28-30DB.
4. Ngokobukhulu bendawo, injineli ikhetha i-eriyali yokulayisha i-spiral ukuze ihambelane ne-resonance frequency ye-GSM, kwaye inzuzo ye-800-920MHZ / 1710-1900MHZ iphezulu njenge-3.3DB kunye nokusebenza kakuhle yi-68%.
5. Ii-antenna ezimbini ngaphambili zazibekwe zodwa ngelaphu leglasi le-epoxy ephezulu yoxinaniso, kunye nezinga lokuzihlukanisa ukuya kuthi ga kwi-25DB, elisombulula ngempumelelo ingxaki yokuphazamiseka kweempawu ezifanayo.
6. Ubungakanani obupheleleyo emva kokuhlanganiswa kokugqibela kwe-antenna yi-45mm ubude * 35MM ububanzi, kwaye baphumelele uvavanyo lwangempela kunye nokwamkelwa kwe-robot ye-Bangbang ehlakaniphile.
Iinzuzo zoqoqosho:
Umthengi uye wasungula ngempumelelo imveliso kwiimarike kwaye uphumelele ukuthengiswa kweeyunithi ze-20,000.
