Peb txhua tus loj hlob hauv lub ntiaj teb uas hluav taws xob thiab cov cables khiav txhua qhov chaw. Qee qhov peb muab zais tawm ntawm qhov pom - faus hauv av, los yog kos hauv cov phab ntsa ntawm peb lub tsev - thaum lwm tus neeg strung raws sab nraum zoov nruab nrab thiab cov yees. Ntau tus neeg siv cov hlua hluav taws xob thiab cab cab txhua txhua hnub los khiav lawv cov khoom siv hluav taws xob.
Cov roj teeb muaj lub zog ntawm lub hwj chim, tab sis lawv khiav qhuav sai, tsis zoo rau qhov chaw, thiab tuaj yeem kim. Yuav tsis zoo nws yog tias peb yuav muab hwj chim rau peb cov twj siv hluav taws xob txhua lub sij hawm peb xav tau, tsis muaj cables thiab tsis xav tau roj teeb? Tias muaj tseeb hluav taws xob, qee zaus kuj hu ua Wireless Power Transmission (WPT) . Nws yuav ua suab zoo li ib yam dab tsi hauv kev tshawb fawb txog science, tiam sis lub hwj chim muaj wireless hnub no thiab zoo li yuav tsum yog ib qho tseem ceeb ntawm peb lub neej yav tom ntej.
Cov Keeb Kwm ntawm Wireless Lub Hwjchim
Tus kws tshawb fawb Nikola Tesla pom muaj hluav taws xob hluav taws xob tshaj 100 xyoo dhau los. Ceeb kev txuag me me ua tau zoo nyob rau hauv cov cheeb tsam no nyob rau xyoo tom qab ntawd yog vim li cas; qee qhov kev koom tes theorists claim cuam tshuam los ntawm lub tuam txhab loj hluav taws xob ntawm lub hnub yog mus liam.
Qhov chaw tshawb nrhiav qhov chaw pib ntawm lub sijhawm xyoo 1960 txhais tau tias lub nplaj teb ntawm kev tshawb fawb hauv wireless lub zog. Thaum lub sijhawm ntev-ntev WPT uas Nikola Tesla tau ua npau suav txog tseem tsis tau raug tsa, kev siv technology tshiab hauv WPT pib luv luv tau mus cuag cov neeg tau txais kev pab thaum xyoo 1990 los ntawm daim ntawv teev cov khoom siv xws li roj fais fab.
Txaus siab rau hauv WPT tau tshwm sim nyob rau hauv xyoo tas los ua tsaug rau qhov chaw ntawm mobile devices. Cov neeg tau nce siab ntxhov siab vim lawv lub xov tooj thiab cov ntsiav tshuaj khiav tawm ntawm lub hnub los yog tau txhaws kom rov txhuam txhua hmo. (Ib qho ntawm cov tuam txhab ua lag luam tshiab hauv qhov chaw no - WiTricity - tau tsim muaj rau qhov laj thawj no.)
Wireless Charging
Short-range wireless charging tseem yog nyob deb tshaj daim ntawv thov WPT siv hnub no. Traditional WPT relies on ib txoj kev hu ua inductive coupling , tiam sis qee cov khoom tshiab siv cov khoom siv magnetic resonance xwb. Ntau yam kev lag luam txawv txav ua haujlwm txuas ntxiv mus rau tus txheej txheem siv technology rau wireless charging.
Ib pawg ntawm cov tuam txhab tsim Wireless Power Consortium hauv 2008 los txhawb Qi , ib qho kev siv tshuab ua lag luam rau wireless uas them nyiaj. Muaj ntau lub xov tooj thiab ntsiav tshuaj muab Qt yug.
Lub hwj chim Matters Alliance ( PMA ) tau tsim hauv xyoo 2012. PMA ncaj qha nrog Qi thiab tau tsim nws tus kheej cov specifications rau kev siv cov tshuab inductive coupling.
Ib lub tshuab thib peb rau wireless them lub npe hu ua Resence siv cov khoom sib nqus resonance . Ib pawg tuam txhab tau tsim cov Alliance Wireless Wireless (A4WP) hauv xyoo 2012 los txhawb txoj kev xav. Xyoo 2014, A4WP thiab PMA tau kos npe cog lus pom zoo los ua kom tau lwm tus qauv.
Txawm tias ntau yam mobile pab txhawb qee cov wireless charging, ntau lwm tus tsis. Wireless charging yuav yuav thoob ntiaj teb kev saws me nyuam raws li cov txheej txheem sib txawv kev paub tab. Feem ntau cov wireless charging dlaws hnub no yuav tsum tau ntaus ntawv nyob rau ntawm los yog ze rau lub chav ua kam lub xov tooj (xws li lev). Cov khoom siv kuj yuav tsum tau qee zaus kuj zoo zoo tso rau kom tsim tau ib qho chaw txuas wireless.
Lub Yav Tom Ntej Wireless Wireless
Muaj ib hnub nws yuav muaj peev xwm mus sim rau hauv hluav taws xob nyob txhua qhov chaw uas peb nyob, tej zaum txawm tias dawb, xws li yog tias ib qho khoom siv yuav tau txais kev pabcuam tib yam kev sib txuas ntawm Wi-nkaus nws siv rau cov ntaub ntawv network. Ob txoj kev ua lag luam thiab kev lag luam ua rau qhov kev pom tsis zoo no tshwm sim txhua lub sij hawm ntev, tab sis;
- Wireless signals ntev tshaj plaws raug kev txom nyem los ntawm kev tuaj yeem , kev cuam tshuam thiab lwm yam teebmeem uas txo lawv txoj haujlwm
- Cov tuam txhab lag luam uas khiav cov lag luam muaj txiaj ntsig ntawm cov kab hluav taws xob cab zog tuaj yeem tiv taus txav mus sim rau kev ntshai nyiaj txiag.
- Kev txhawj xeeb dhau lub sij hawm ntev ntawm cov kab mob kis tau ntawm tib neeg lub cev mob siab
