Xav tau lub caj npab hais kom ua tsis raws koj lub cuab yeej kom them? Nov yog txoj haujlwm. Kuv Wireless Power Transmitter thiab Receiver combo uas yuav ua raws koj lub cuab yeej…..tsis ntev li nws txog peb ntiv tes.

Khoom siv:

  • Kev cai luam tawm cov laug cam (cov duab thiab cov ntawv teeb tsa kom ua raws)
  • Custom Servo Mounts (cov ntaub ntawv ua raws)
  • 4.95uH Kis Kis
  • 2 x SG90 Servos
  • 3.7V LiPo Roj Teeb
  • 19V Laptop Lub Hwj Huam Fais Fab
  • Polycarbinate 3in x 5in E.

Kauj Ruam 1: Schematics thiab PCBs: Tsim Kev Hloov Kho thiab Kho Kom Zoo

Txog qhov haujlwm no kuv txiav txim siab xaj ib lub rooj ntoo liab qab los ntawm lub tsev tsim thiab txiav lwm qhov nrog LPKF laser txiav. Ob leeg ua haujlwm tab sis vim yog qhov nyiaj dhau los ntawm qhov vias kuv xav hais kom xaj cov laug cam tsis txhob txiav lawv tus kheej. Ob qho ntawm cov laug cam yog ua los ntawm ESP32 microcontroller uas ua txuas rau txoj haujlwm no dhau WiFi lossis Bluetooth yooj yim heev, txawm li cas los xij rau txoj haujlwm no lawv tau teeb tsa tsuas yog txuas rau lawv tus kheej thaum qhib.

Kuv kuj siv Eagle rau schematic capture thiab board layout. Vim tias Eagle tam sim no muaj los ntawm Autodesk nws ua ke tau zoo nrog lawv cov cuab yeej kos duab zoo li Fusion360 thiab Inventor. Qhov no tso cai rau kuv los tshuaj xyuas cov tshuab haum rau tiv thaiv kev teeb tsa pawg sai thiab yooj yim.

  1. Txheeb xyuas ob qho tib si ntawm kab lus thiab ua qhov hloov pauv uas xav tau.
  2. Yog tias koj npaj yuav hloov ib qho ntawm cov coils kom ntseeg tau tias cov khoos phis tawj sib txuas nrog cov nqi inductance ntawm cov kauj tshiab. Kuj xyuas kom cov coils tuav 3: 1 inductance piv

Kev piav qhia Circuit: Transmitter

Qhov kev tsim qauv no muaj ob ntu tseem ceeb ntawm kev sib tham: thawj yog kev sib txuas lus/kev tswj hwm thiab qhov thib ob yog lub suab sib txuas rau cov xov hluav taws xob xa xov WPT zaus yog nyob ntawm 127KHz thiab tuaj yeem tswj tau txog 10W. Cov kis tau tus mob yog qhov hloov pauv series resonant Circuit. Lub rooj tsavxwm tag nrho tuaj yeem siv hluav taws xob los ntawm 18VDC txog 36VDC yog li koj lub khoos phis tawj lub zog siv hluav taws xob yuav ua haujlwm zoo rau txoj haujlwm no.

Cov lus piav qhia hauv Circuit: Txais

Kev tsim qauv no kuj tseem nyob ib puag ncig ESP32 tab sis kuj tseem siv LTC4120. Cov nti no tau tsim tshwj xeeb los ua WPT tus txais thiab muaj peev xwm tshem tawm cov neeg txais khoom Circuit Court xws li qhov raug ntawm lub hwj chim raug muab rau hauv kab ke. Cov nti kuj tseem muaj ib lub xov tooj ntawm tes LiPo them nqi hluav taws xob nrog ntau qhov kev nyab xeeb zoo li kev tiv thaiv tam sim no thiab them sijhawm tas.

Kauj Ruam 2: Txiav txim PCBs

Muaj ntau lub tsev pawg thawj coj saib xyuas uas tuaj yeem yuav cov laug cam. Yog tias koj yog tub ntxhais kawm ntau ntawm lawv kuj tseem muaj nyiaj cheb yog tias koj muaj tsev kawm ntawv email chaw nyob.

  • Kev Tshawb Fawb Ntau Tshaj (4PCB)
  • Sunstone Circuits
  • JLC PCB
  • PCBWay
  • Kub Pheonix

Yog tias koj kuj tsis xav kom sau koj lub rooj tsavxwm nrog ntu koj tuaj yeem ua los ntawm lawv cov neeg ua ntej kom tau nyiaj ntxiv me ntsis. Nco ntsoov ntau qhov chaw no siv cov tsev sab nrauv.

  • Screaming Circuits
  • JLC PCB
  • CircuitHUB
  • TurnKey PCB

Nyob ntawm lub rooj tsavxwm lub tsev lawv yuav xav tau qee cov ntaub ntawv qee zaum hauv cov qauv sib txawv. Yog tias koj tab tom xaj tsuas yog cov laug cam qhov no tsis tshua muaj teeb meem li gerbers yog cov ntaub ntawv xaiv rau feem ntau cov tsev zoo. Hauv qab no yog cov npe ntawm cov ntaub ntawv koj xav tau rau kev daws teeb meem.

  1. Pawg Gerbers:.grb
  2. BOM:.xlsx (Qhov no feem ntau yog nyob rau hauv cov lus hais los ntawm pawg thawj coj saib xyuas tsev; feem ntau lawv txuas qhov kev hloov pauv (siv tus lej tsim ib feem)) rau txhua feem.
  3. Centroid:.xlsx (Cov ntaub ntawv no hu tawm qhov chaw thiab kev taw qhia ntawm txhua qhov chaw raws li keeb kwm thiab ref des)
  4. Txheej Stackup (Qhov no tsis tas yuav tsum tau tab sis zoo kom muaj)

Kauj Ruam 3: Luam Tshooj

Luam Qhov
Luam Qhov

Muaj peb ntu los luam tawm:

  1. Upper Servo Caj Npab
  2. Qis Servo Caj Npab
  3. Caj npab puag

Kauj ruam 4: Flashing Code

Txhua qhov chaws tau sau hauv Arduino IDE siv ESP32 cov tsev qiv ntawv los ntawm Espressif. Txhawm rau teeb tsa USB-> UART cov tsav tsheb nrog rau cov ntaub ntawv txhawb nqa lub rooj thov ua raws qhov txuas no:

Ntau ntawm cov cai no yog ua los ntawm Espressiff's ESP32 cov tsev qiv ntawv thiab lawv cov lus pom thiab cov lus pom tau los ntawm lawv, Tsis yog kuv.

Kev Ua Haujlwm Zoo Tshaj Plaws

Tus xa tawm yog qhov tseeb WiFi "qhev" hauv kev teeb tsa no. Qhov no yog vim tus neeg txais yog tus txiav txim siab xa nws cov ntaub ntawv taw qhia mus rau pawg thawj coj saib xyuas. Ntawm khau raj, pawg thawj coj yuav pib nws tus kheej ua lub wireless nkag mus tos rau kev sib txuas los ntawm "tus tswv" ESP32. Tom qab qhov no nws pib IO thiab tos rau kev txuas. ib zaug txuas nrog LED liab yuav qhib thiab pib gimballing.

Txais Kev Ua Haujlwm

Ntawm khau raj, tus txais tau pib ua yog nkag mus thiab pib nrhiav "qhev". Thaum pom lawv sib tham "channel" kom ua haujlwm thiab txav mus rau nws. Thaum muaj qhov program ntawd tshawb xyuas cov ntaub ntawv ntsuas lub ntsuas thiab pib xa nws mus rau lub rooj xa ntawv. Yog tias lub cuab yeej "qhev" tsis tuaj yeem pom qhov haujlwm yuav txuas ntxiv rov ua haujlwm nws WPA kev sib txuas thiab txuas ntxiv mus.
