Miyezo Yogwiritsa Ntchito Chaja Yopanda Waya

Pofuna kupangitsa kuti zinthu zamitundu yosiyanasiyana zizigawana ma charger omwewo ndikusintha kusinthasintha kwa ma charger opanda zingwe, bungwe loyamba padziko lonse lapansi lolimbikitsa ukadaulo wopangira ma waya opanda zingwe, Wireless Power Consortium (yomwe imadziwika kuti "Alliance"), yakhazikitsa mulingo wa "charging opanda zingwe". Pansi pa mulingo wa Wireless Power Consortium (WPC), kugwiritsa ntchito magetsi opanda zingwe ndi 0 ~ 5W yokha. Dongosolo lomwe limakwaniritsa mulingo woterewu limagwiritsa ntchito kulumikizana kwa inductive pakati pa ma coil awiri a planar kusamutsa mphamvu kuchokera pa chowulutsira mphamvu kupita ku cholandila mphamvu. Mtunda pakati pa ma koyilo a pulayimale ndi achiwiri nthawi zambiri amakhala 5mm, ndipo kuwongolera kwamagetsi kumayendetsedwa ndi kuzungulira kwa digito padziko lonse lapansi. Panthawiyi, wolandila mphamvu amalankhulana ndi chotumizira magetsi ndikupanga kugwiritsa ntchito mphamvu. Kulankhulana uku ndi njira imodzi- yolankhulirana kuchokera kwa cholandirira magetsi kupita ku chowulutsira mphamvu kudzera mu kusintha kwa ma backscatter. Mu kusintha kwa backscatter, wolandila mphamvu amasintha katunduyo, motero amasintha magwiritsidwe apano a chotengera mphamvu. Zosintha zapanozi zimawunikidwa ndikusinthidwa kukhala chidziwitso chofunikira kuti zida ziwirizi zizigwira ntchito limodzi. Njira yolumikizirana imaphatikizapo analogi, ma pulses a digito (ping), chizindikiritso, kasinthidwe, ndi kutumiza mphamvu.

Njira zoyambira zomwe zimachitika pomwe cholandirira magetsi chayikidwa pa cholumikizira mphamvu ndi motere:
(1) Ping ya analogi yochokera ku chotengera mphamvu imazindikira kukhalapo kwa chinthu.
(2) Ping ya digito yochokera ku chopatsira mphamvu ndi mtundu wotalikirapo wa ping ya analogi ndipo imalola nthawi kuti wolandila mphamvu ayankhe ndi paketi yamphamvu yazizindikiro. Ngati paketi yamphamvu ya siginecha ndiyovomerezeka, chowulutsira mphamvu chimasunga koyiloyo kukhala ndi mphamvu ndikupitilira sitepe yotsatira.
(3) Panthawi yozindikiritsa ndi kusinthika, wolandila mphamvu amatumiza mapaketi angapo a data kuti adzizindikiritse okha ndikupereka chidziwitso chokonzekera ndi kukhazikitsa kwa chopereka mphamvu.
(4) Panthawi yosinthira mphamvu, wolandila mphamvu amatumiza mapaketi olakwika owongolera ku cholumikizira mphamvu kuti awonjezere kapena kuchepetsa mphamvu. Panthawi yogwira ntchito bwino, mapaketi olakwika owongolera amatumizidwa pafupifupi pafupifupi 250ms ndi 32ms iliyonse pakasintha kwakukulu. Kuphatikiza apo, pakamagwira ntchito bwino, chowulutsira mphamvu chimatumiza mapaketi amagetsi ma 5s aliwonse.
(5) Kuti athetse kusamutsa mphamvu, wolandila magetsi amatumiza uthenga wa "kutha kwa kuyitanitsa" kapena samalumikizana ndi ma 1.25s, zomwe zimapangitsa cholumikizira magetsi kuti chilowe m'malo otsika-mphamvu. Pansi pa mulingo wa Qi, mafoni a m'manja, makamera, makompyuta ndi zinthu zina zimatha kulipiritsidwa ndi ma Qi opanda zingwe, zomwe zimapangitsa-kuchajisa opanda zingwe kutheka.
