2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Txoj haujlwm no yog npaj rau txhua tus uas muaj Raspberry Pi qhov haujlwm uas siv Python uas xav ntxiv kev tswj lub suab ntawm lawv cov khoom siv Amazon Echo uas twb muaj lawm. Koj tsis tas yuav yog tus kws paub dhau los, tab sis koj yuav tsum xis nyob siv kab hais kom ua thiab hloov kho cov cai uas twb muaj lawm kom haum rau koj cov kev xav tau.

Kuv tau pib tawm ntawm qhov haujlwm kom pab kuv Raspberry Pi kom tswj tau lub suab nrog Alexa kom nws tuaj yeem ua kom dej sov hauv lub lauj kaub rau qhov kub tshwj xeeb. Txawm hais tias kev sib cuam tshuam kuv xav tau yooj yim heev (dhau ib tus lej los ntawm Alexa mus rau Raspberry Pi), nws tau ua haujlwm ntau kom tau mus rau lub xeev ntawd los ntawm cov kev qhia uas twb muaj lawm. Kuv vam tias qhov kev qhia no yuav ua rau cov txheej txheem ntawd nrawm li sai tau rau lwm tus.

Hauv kuv qhov piv txwv, Kuv pib nrog Raspberry Pi Zero W nrog Raspbian. Kuv muaj qhov program Python3 ntawm kuv tus Pi uas muaj peev xwm sau ntawv mus rau SPI zaub, thiab kuv muaj lub ntsuas kub ntsuas kub uas kuv tuaj yeem nyeem tau. Rau koj, txoj haujlwm no yuav luag txhua yam, tab sis lub tswv yim yog tias koj yuav muaj qee yam khoom siv uas koj xav nyeem ntawm Alexa thiab/lossis qee yam khoom siv tso tawm uas koj xav tswj siv Alexa.

Lub hom phiaj yog mus los ntawm txoj haujlwm yooj yim xws li qhov tau piav qhia saum toj no mus rau lub cuab yeej uas koj tuaj yeem tswj tau yooj yim nrog kuv Echo. Piv txwv tias koj muaj cov cuab yeej kho mob no lawm, txoj haujlwm no yuav tsum tsis txhob them nyiaj rau koj. Thaum kawg, koj yuav mus txog qhov chaw uas koj tuaj yeem hais tej yam xws li:

Kuv: "Alexa, nug kuv lub cuab yeej los ntsuas qhov ntsuas kub ntawm lub ntsuas 1."

Alexa cov lus teb: "Qhov kev sojntsuam nyeem 72.31 degrees."

los yog

Kuv: "Alexa, qhia kuv lub cuab yeej sau George Washington"

Lus Teb: Cov zaub txuas nrog kuv Raspberry Pi tam sim no nyeem "George Washington"

Hauv ntu tom ntej, Kuv yuav piav qhia qhov yuav tsum tau tshwm sim nyob tom qab lub luag haujlwm kom ua txoj haujlwm no. Yog tias koj tsuas yog xav kom qhov no ua haujlwm ntawm koj txoj haujlwm thiab tsis quav ntsej nws ua haujlwm li cas, tsis txhob hla nws (txawm hais tias nws yuav ua rau nws nyuaj dua yog tias muaj qee yam tsis raug).

Kauj ruam 1: Tom qab

Hauv daim duab no (credit: https://developer.amazon.com/en-US/docs/alexa/alex… peb tuaj yeem pom cov qauv dav dav rau Alexa Gadgets.

Thaum koj hais qee yam rau koj lub cuab yeej Echo, nws xa lub suab mus rau Alexa Cloud, qhov twg nws tau ua tiav thiab qhov twg cov lus teb tau tsim los teb rau koj. Thaum koj nug tias huab cua yog dab tsi, nws tsuas yog ob qho no hauv kev sib tham. Tam sim no xav tias koj xav ntxiv kev tswj lub suab rau ib qho ntawm koj txoj haujlwm me me ntawm Raspberry Pi. Kev ua txhua yam onboard yuav xav tau cov cuab yeej tseem ceeb thiab lub codebase ntse heev kom tau txais yam mus. Kev daws teeb meem zoo dua yuav yog siv Alexa Cloud, uas yog qhov ntse heev thiab tau txais txiaj ntsig zoo ntawm kev tuav cov lus nyuaj. Alexa Gadgets muab txoj hauv kev zoo rau koj los ua qhov no.

Alexa Gadget sib txuas lus nrog Echo ntaus ntawv siv bluetooth. Thaum qhov kev sib txuas no tau tsim, ob leeg sib txuas lus siv UTF-8 encoding. Thaum Echo hla qee yam mus rau lub cuab yeej, nws hu ua kev qhia. Lwm qhov kev taw qhia raug xa mus ua qhov xwm txheej. Ua ntej nkag mus rau qhov tseeb ntws ntawm txhua qhov no, peb yuav tsum qhia lwm qhov tseem ceeb: kev cai Alexa Kev Txawj Ntse.

Alexa tso cai rau cov tsim khoom los tsim lawv tus kheej kev txawj ntse, uas tso cai rau lawv los tsim lawv tus kheej kev sib cuam tshuam thiab tus cwj pwm coj los siv rau txhua yam khoom siv Echo. Piv txwv li, tus tsim tawm tuaj yeem tsim cov txuj ci tshwj xeeb los qhia koj txog qhov deb ntawm ob lub tshav dav hlau hauv Asmeskas. Ib tus neeg siv yuav hais tias: "Alexa, nug kuv tus lej kev suav nrug deb li cas ntawm LAX thiab JFK" thiab nws tuaj yeem teb nrog "2475 mais". Nws ua li no li cas? Thaum tus tsim tawm tsim cov txuj ci tshwj xeeb, lawv txheeb xyuas dab tsi hu ua "kev cai xav tau" nrog "piv txwv cov lus hais" uas muaj "qhov qhib". Piv txwv li, hauv qhov txuj ci no kuv yuav muaj lub hom phiaj "calc_dist" los xam qhov deb ntawm ob lub ntsiab lus. Ib qho piv txwv hais yuav yog "qhov kev ncua deb nruab nrab ntawm {slot1} thiab {slot2}" lossis "deb npaum li cas ntawm {slot1} thiab {slot2}". Cov kab lus qhia hauv kab zauv muaj hom tshwj xeeb. Hauv qhov no cov hom no yuav yog lub tshav dav hlau lis dej num xws li LAX, JFK, BOS, ATL. Thaum ib tus neeg siv nug txog qhov kev txawj ntse, Alexa Cloud sim ua kom zoo li cas tus neeg siv hais rau qhov kev cai ua raws li siv cov lus piv txwv muab thiab sim nrhiav qhov txiaj ntsig qhov txiaj ntsig rau qhov kev thov ntawd. Hauv qhov piv txwv no, nws yuav pom tias tus neeg siv xav tau "calc_dist" lub siab thiab qhov slot1 yog LAX thiab slot2 yog JFK. Txij ntawm no mus, Alexa Cloud dhau qhov haujlwm mus rau tus tsim tawm tus kheej txoj cai. Yeej, nws qhia tus tsim tawm txoj cai dab tsi nws tau txais thiab dab tsi txhua qhov txiaj ntsig qhov yog, ntawm lwm cov ntsiab lus.

Tus tsim tawm tau txiav txim siab qhov twg lawv cov cai nyob, tab sis qhov kev xaiv nrov heev yog siv AWS Lambda ua haujlwm. Yog tias koj tsis paub tias yog dab tsi, nws yog qhov tseem ceeb kev pabcuam uas tso cai rau koj rub cov lej uas tuaj yeem ua haujlwm tau txhua lub sijhawm thiab tom qab ntawd tsub koj tsuas yog rau lub sijhawm uas koj cov cai tau khiav. Yog tias peb txuas ntxiv nrog peb tus piv txwv, tus tsim tawm txoj cai yuav yog Python ua haujlwm uas tau txais ob lub tshav dav hlau cov cai, saib lawv qhov chaw, suav qhov nrug deb, thiab tom qab ntawd xa cov lus teb rov qab rau Alexa Cloud los tham qee yam rau tus neeg siv. Alexa Cloud yuav xa cov lus hais ntawd rov qab rau tus neeg siv lub cuab yeej, thiab lawv yuav tau txais cov lus teb.

Tam sim no peb tuaj yeem rov qab mus rau lub gadget. Peb tuaj yeem tsim cov kev txawj uas tsim los ua haujlwm tshwj xeeb nrog cov khoom siv. Tus tsim tawm tuaj yeem sau qhov txuj ci uas xa tawm cov lus qhia rau lub cuab yeej txuas nrog. Cov lus qhia ntawd muaj kev them nyiaj uas tuaj yeem siv tau txawm li cas los xij nws xav tau los ntawm lub cuab yeej. Qhov txuj ci ntawd tseem tuaj yeem xa cov lus qhia thiab tom qab ntawd mloog qhov xwm txheej los ntawm lub cuab yeej kom cov txuj ci muaj peev xwm nkag tau cov ntaub ntawv xa los ntawm lub cuab yeej.

Kev tsim cov dej ntws no tso cai tsim cov cuab yeej muaj zog heev vim tias cov cuab yeej pheej yig tuaj yeem muaj peev xwm sib txuas lus nrog cov cai hauv huab thiab teb cov lus txib siv qee qhov kev paub lub suab zoo tshaj plaws muaj.

Nws yuav tsum raug sau tseg tias feem ntau cov txuj ci tso cai rau ntau txoj hauv kev los cuam tshuam nrog lawv. Piv txwv li, tus neeg siv tuaj yeem dhia ncaj qha mus rau lub hom phiaj los ntawm kev hais "Alexa, nug kuv qhov kev suav nrug deb li cas ntawm LAX thiab JFK" (hu ua kev txhaj tshuaj ib zaug) lossis lawv tsuas yog siv lub hom phiaj pib: "Alexa, qhib kuv tus kheej kev suav nrug deb ". Qhov piv txwv kawg no feem ntau yuav ua raws los ntawm Alexa teb nrog rau qhov xav paub ntxiv. Cov ntawv qhia no txhob txwm tso tseg kev txhawb nqa rau tom kawg. Tshwj xeeb tshaj yog, yam tsis hloov kho txoj haujlwm Lambda, koj tsuas tuaj yeem hais tawm qhov txuj ci siv kev txhaj tshuaj ib zaug. Qhov kev xaiv tsim no tso cai rau tus qauv kom yooj yim dua (tsis tas yuav txhawb nqa lub hom phiaj lossis kev sib tham), thiab kuv tau pom tias kuv feem ntau xav sib cuam tshuam nrog kuv cov cuab yeej siv ib qho kev txhaj tshuaj ib txwm hais vim lawv feem ntau nrawm dua.

Kauj Ruam 2: Sau npe Gadget ntawm Alexa Voice Service Developer Console

Cov hauv qab no yog cov lus piav qhia ntawm cov kauj ruam xav tau. Kuv tau tsim cov vis dis aus sib npaug uas qhia tias yuav ua li cas txhua qib no. Koj tuaj yeem siv ib qho, lossis ob qho tib si, ua kom tiav cov theem no.

Ib tsab ntawv ntawm tus nqi ntawm kev tuav ntawm AWS: Phau ntawv qhia no xav kom koj muaj AWS tus lej (pub dawb los tsim). Lambda ua haujlwm tau them nyiaj, txawm li cas los xij, lawv cov nqi tam sim no hauv cheeb tsam N. Virginia yog $ 0.000000208 rau 100ms siv nrog 128MB nco. Txog kev siv, txhua qhov kev thov ntawm kuv cov txuj ci nqi txog 800ms ntawm kev siv ntawm qib no. Txhawm rau khaws cov nqi ntawm $ 1.00USD, koj yuav tsum tau thov qhov haujlwm no txog 600, 000 zaug uas (yog tias nws siv koj li 5 vib nas this ib qhov kev thov) yuav coj koj hla 34 hnub ntawm kev hu tsis tau koj li haujlwm. Tus nqi yuav tsum tsis yog qhov teeb meem tseem ceeb tshwj tsis yog koj tshaj tawm koj cov txuj ci thiab muaj coob tus neeg pib siv nws. Yog tias koj txhawj xeeb txog kev tau txais cov nqi ntawm AWS, txiav txim siab teeb tsa lub tswb siv uas ceeb toom rau koj yog tias kev siv hla dhau qhov pib txhais.
