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

Nov yog qhov kev qhia thib ob rau Nabito [qhib qhov (socket)), thawj qhov tuaj yeem pom ntawm: Nabito [qhib qhov rooj] v1

Kuv teev cov laj thawj rau tsim txoj haujlwm no hauv kab ntawv blog no: EVs tsis muaj ntsiab lus rau cov neeg nyob hauv tsev

Nws yog dab tsi?

Nabito - lub qhov (socket) qhib yog IoT ntse ntsuas nrog ntsuas hluav taws xob, qhib/tawm qhov hloov pauv siab, NFC sensor, kev tso cai ntawm tus neeg siv, kev muaj peev xwm them nuj nqis thiab kev tswj hwm cov neeg siv.

Txoj haujlwm muaj ob ntu: 1. lub thawv tswj (IoT ntaus ntawv) 2. web app frontend/backend, ob qho tag nrho qhib-qhov.

1. Lub thawv tswj muaj cov khoom yooj yim-rau-tau online thiab tau tsim los ua qhov ntse thiab tseem pheej yig cov khoom siv hluav taws xob rau cov pej xeem thiab ntiag tug nres tsheb kom them nyiaj qeeb ntawm cov tsheb hluav taws xob. Nws khiav ntawm Raspberry Pi Zero W thiab Arduino Nano.

2. Lub vev xaib app khiav ntawm Ruby on Rails thiab muaj nyob raws li qhib qhov chaw ntawm Github: https://github.com/sysdist/nabito-server Kev sib txuas ntawm lub npov thiab lub vev xaib app tau ua tiav los ntawm MQTT raws tu qauv.

Lub hom phiaj ntawm txoj haujlwm yog txhawm rau txhim kho qhov qhib them lub network uas txhua tus tuaj yeem siv thiab siv lossis txuas ntxiv.

Lub thawv tswj muaj cov khoom yooj yim-rau-tau online thiab tau tsim los ua qhov ntse thiab tseem pheej yig cov khoom siv hluav taws xob rau cov pej xeem thiab ntiag tug qhov chaw nres tsheb kom them nyiaj qeeb ntawm cov tsheb hluav taws xob.

Nws khiav ntawm Raspberry Pi Zero W ib leeg-board computer (SCB). Tus nqi tag nrho ntawm lub thawv tswj yog ib puag ncig € 60.

Nabito - lub qhov (socket) qhib tam sim no tau tsim los them rau lub qhov (socket) zoo tib yam, hauv Tebchaws Europe txuas ntxiv nws yog 230V thiab 10 -13A, piv txwv li cca. 2.9kW nruam. Tab sis lub tswv yim siv rau txhua lub qhov (socket), Euro, Asmeskas lossis UK lossis lwm yam, cov phiaj xwm yav tom ntej ntawm txoj haujlwm yuav suav nrog 2 thiab 3 theem kev teeb tsa.

Qhia:

• Tib PhaseVoltage: 230 V
• ACMax. tam sim no: 13A
• Lub zog: 2.9 kW
• Loj: 240x200x90mm
• Kev sib txuas: RJ45 LAN txuas lossis WIFI
• Kev ua raws IP: IP55

Cov ntawv qhia hauv qab no tsis tiav, nws ploj qee qhov kab duab kab, qee cov kauj ruam sib dhos, thiab lwm yam), Kuv xav kom nws tawm sai li sai tau, yuav ua haujlwm txhim kho nws maj mam, yog li thov, yog tias phau ntawv qhia no tsis ua npog txhua yam koj xav paub lossis yog koj muaj lus nug, xa email rau kuv. Ua tsaug rau kev nkag siab.

Kauj Ruam 1: Nws Ua Dab Tsi?

Txoj haujlwm muaj ob ntu, lub thawv tswj lub cev uas yog IoT yam (tus neeg siv khoom) thiab muaj Daim Ntawv Thov Lub Vev Xaib uas tswj nws (server sab).

1. On/Off switchingWith a mains relay and a contactor nws tuaj yeem hloov lub qhov hluav taws xob qhov hluav taws xob rau/tawm raws li cov neeg siv cuam tshuam.

2. Kev ntsuas hluav taws xob

Lub thawv tswj ntsuas AC tam sim no thiab teev lub zog siv. Txuj kev ntsuas ua haujlwm. Kev ntsuas lub zog tau ua tiav rau ib tus neeg siv. Tam sim no tsuas muaj AC saib xyuas tam sim no, tsis muaj kev saib xyuas hluav taws xob ntawm qhov no.

3. Cov neeg siv pov thawj

Koj yuav tsum tsim cov neeg siv nyiaj rau cov neeg siv uas yuav siv lub qhov (socket)/s. Tus neeg siv tso cai los ntawm kev nyeem QR code lossis siv daim ntawv NFC. Lub vev xaib sib cuam tshuam rau tus neeg siv tso npe, nkag mus thiab siv lub thawv tswj lossis NFC lossis hloov lub thawv rau/tawm ncaj qha. Admin tuaj yeem pom zoo, tsis pom zoo cov neeg siv.

4. Kev them nqi

Raws li tus thawj tswj hwm lub qhov (socket) teeb tsa thiab tus nqi rau 1kWh cov nqi raug tsim rau ib tus neeg siv raws li lawv lub zog siv. Cov nuj nqis txhua hli yuav tsim tom qab kom yooj yim rau admin.

AC cov kab hluav taws xob txuas hluav taws xob muab rau:

• AC contactor
• Lub ntsiab relay
• Txawb xov tooj uas siv zog Raspberry Pi thiab Arduino

Cov zis los ntawm AC contactor mus rau lub qhov (socket). Lub ntiaj teb tiv thaiv tau txuas nrog los ntawm cov kab hluav taws xob txuas mus rau lub qhov hluav taws xob.

Raspberry Pi tswj hwm lub xov hluav taws xob xa hluav taws xob thiab kev xa xov hluav taws xob tig tig rau/tawm ntawm tus contactor.

9. txheeb xyuas daim nqi rau kev siv lub qhov (socket) kawg
10. Tom qab kev sim ua tiav, pib tsim koj tus kheej EV them nyiaj network
11. Nyiaj tau;-)

Kauj Ruam 10: Qhov Xaus, Cov Teeb Meem thiab Cov Khoom Taw Qhia

Hauv qhov version ntawm Nabito tswj lub thawv Kuv tuaj yeem txiav tawm lub thawv tswj thiab lub vev xaib app qhov tseem ceeb tsim IoT (Internet ntawm Yam) project nrog ob qho tib si ntawm lub cev uas ua qee yam muaj txiaj ntsig thiab rov qab-kawg app thiab kev pabcuam uas tswj hwm yam khoom.

Tus nqi ntawm lub npov tau nce me ntsis los ntawm qhov kawg version (v1 ua ntej: € 50, v2 tam sim no: € 60), vim tias kuv ntxiv tus tiv tauj rau lub hom phiaj kev nyab xeeb kom ua haujlwm siab dua amps thiab RPi kuj kim dua me ntsis tom qab ntawv OrangePi.

MQTT yog siv los ua tus txheej txheem tseem ceeb rau kev khaws cov ntaub ntawv thiab tswj lub thawv.

Txij li qhov kawg ntawm Nabito, kuv muaj peev xwm daws tau feem ntau ntawm cov teeb meem (Wifi, tus tiv tauj, lub tshuab ua kom sov dhau, lub qhov hluav taws xob sib txuas, thiab lwm yam). Txawm li cas los xij daim ntawv teev cov teeb meem tam sim no thiab cov hauv kev loj hlob ntxiv:

Teeb meem:

• Raspberry Pi Zero W yog pawg thawj coj zoo heev, nrog Wifi thiab Bluetooth thiab 2 GPIO pins, tab sis tseem lub tshuab ua kom sov txog 34C thaum tsis ua haujlwm uas tuaj yeem muaj teeb meem hauv huab cua sov thiab lub caij ntuj sov nrog tshav ntuj ncaj qha
• Khiav Linux hauv lub thawv tswj yog qhov zoo rau kev tsim qauv, tab sis cov qauv tsim khoom ntawm cov khoom no yuav tsum zaum ua haujlwm ntawm pawg thawj coj uas muaj peev xwm ntawm TLS/SSL (nti ESP32 zoo li muaj kev cia siab)

Cov cib fim:

• tsim cov qauv rau qhov siab dua tam sim no (ua haujlwm zoo ib yam, tab sis siv cov neeg sib txuas nrog cov amps siab dua thiab sib txawv CT cov cim/lub zog saib xyuas cov qauv)
• tsim cov qauv rau 2 thiab 3 theem
• sib koom ua ke saib xyuas lub zog (zoo li Peacefair PZEM-004T Lub zog saib xyuas)
• txav mus rau ESP32 kom muaj zog ntxiv thiab ua kom sov sov
• koom ua ke rau AWS IOT huab thiab siv cov ntawv pov thawj rau kev teeb tsa kev nyab xeeb zoo tshaj (tam sim no tsuas yog MQTT tus neeg siv/tus lej siv)
• tswj cov ntawv pov thawj thiab MQTT daim ntawv pov thawj los ntawm lub vev xaib app (tam sim no qhov no tau teeb tsa tus kheej dhau los tom qab kawg)
• ntxiv me me LCD vaj huam sib luag los nthuav qhia ncaj qha ntawm Nabito lub thawv tswj
• ntxiv tus lej lej los muab khawm sib cuam tshuam nrog lub thawv (tus lej muaj peev xwm rau kev nyab xeeb ntxiv)
• suav nrog tus ntsuas kub ntxiv los soj ntsuam qhov kub ib puag ncig ntawm lub thawv
