Daim ntawv thov hais txog dab tsi?

OfficeHelperBOT yog daim ntawv thov tsom mus rau qhov chaw ua haujlwm ntse. 2 Raspberry Pi 3 Qauv B yuav teeb tsa rau qhov no.

Raspberry Pi 1 yuav yog lub tshuab tseem ceeb uas yuav suav nrog txhua qhov txiaj ntsig los ntawm cov ntsuas, tshaj tawm cov ntaub ntawv ntawm MQTT, khaws cov ntaub ntawv rau hauv huab database uas peb siv DynamoDB thiab khiav lub web portal server.

Raspberry Pi 2 yuav raug siv ntawm lub qhov rooj. Nws yuav xav kom tus neeg ua haujlwm txheeb xyuas lawv tus kheej ua ntej lawv raug tso cai nkag mus rau hauv chaw ua haujlwm. Muaj ob txoj hauv kev los ua qhov no uas yog los ntawm tus lej lej lej thiab QR code pov thawj. Hauv cov xwm txheej uas kev txheeb xyuas yuav raug siv tsis raug, peb yuav thaij duab ntawm leej twg uas tsis tau ua pov thawj tsis tiav thiab khaws tus neeg daim duab mus rau AWS S3 Bucket.

Lub vev xaib yuav tuaj yeem saib DHT, lub teeb, lub suab pom cov duab thiab yees duab ntawm lub chaw haujlwm. Lub vev xaib tseem tuaj yeem tuaj yeem tswj lub teeb chaw ua haujlwm thiab tseem saib lub kwj deg ntawm CCTV ntawm lub chaw haujlwm.

Tseem yuav muaj Telegram bot uas tso cai tswj rau lub teeb LED hauv chaw ua haujlwm, txheeb xyuas tus nqi ntawm lub ntsuas qhov ntsuas xws li ntsuas kub thiab tseem tso cai rau cov neeg ua haujlwm kom tau txais lawv daim QR code duab yog tias lawv tshwm sim poob lawv cov duab QR lossis tsis nco qab lawv tus pin los ntawm kev thov thiab tau txais lawv daim QR code duab los ntawm AWS S3 Bucket.

Kauj Ruam 2: Teeb Rau Raspberry Pi 1 (Chaw Ua Haujlwm)

1. Tsim daim nplaub tshev khaws koj li html hu ua qauv
2. Tsim daim nplaub tshev los khaws koj cov ntaub ntawv css/javascript hu ua zoo li qub
3. Tsim daim nplaub tshev khaws koj lub koob yees duab cov ntaub ntawv hu ua lub koob yees duab nrog 3 daim nplaub tshev capture_photos, motion_photos, motion_videos

mkdir ~/ca2

mkdir ~/ca2/qauv

mkdir ~/ca2/zoo li qub

mkdir ~/ca2/zoo li qub/lub koob yees duab

mkdir ~/ca2/zoo li qub/lub koob yees duab/capture_photos

mkdir ~/ca2/zoo li qub/lub koob yees duab/motion_photos

mkdir ~/ca2/zoo li qub/yees/motion_Videos

Kauj Ruam 3: Teeb Rau Raspberry Pi 2 (Qhov Rooj)

1. Tsim daim nplaub tshev los khaws koj cov ntaub ntawv hu ua qhov rooj
2. Tsim daim nplaub tshev khaws koj li QR Code cov duab hu ua qr_code

mkdir ~/qhov rooj

mkdir ~/qhov rooj/qr_code

Kauj Ruam 4: Teeb Telegram Bot

1. Qhib Telegram
2. Nrhiav "BotFather"
3. Hom "/pib"
4. Hom "/newbot"
5. Ua raws li cov lus qhia, lub npe rau bot, lub npe siv rau bot, sau rau bot kev txheeb xyuas tus lej cim

Kauj ruam 5: Teeb DynamoDB

1. Sign up for AWS
2. Nrhiav DynamoDB hauv AWS Kev Pabcuam
3. Nyem "Tsim cov lus"
4. Sau lub npe lub npe
5. Teem muab faib qhov tseem ceeb ua 'id' (Txoj hlua) thiab Ntxiv Ntxiv Qhov Tseem Ceeb ua 'datetime' (String)
6. Ua rau 4 lub rooj, dht, teeb, duab, neeg ua haujlwm

Saib ua ntej ntawm 4 Cov Ntxhuav

Kauj Ruam 6: Teeb AWS S3 Bucket

1. Search AWS S3
2. Nyem rau ntawm "Tsim thoob"
3. Ua raws li cov cai teev npe lub thoob
4. Ua raws cov screenshots
5. Tsim Thoob

Kuv yuav ua li cas thiaj li upload rau hauv S3 thoob?

Peb tsis muaj tus thawj tswj hwm lub portal yog li peb yuav ua tus kheej ntshuam QR Code duab los ntawm AWS nraaj tus neeg siv-interface. Ua raws cov screenshots los tsim lub thoob. Cov ntawv luv ntawm cov cai yog cov laj thawj xav tau txhawm rau rub cov duab mus rau S3 Thoob

Kauj Ruam 7: Teeb tsa AWS SNS

1. Search AWS SNS
2. Ua raws li Topic Tag
3. Tsim cov ncauj lus tshiab
4. Teem lub npe lub npe thiab tso saib lub npe

Kauj ruam 10: Cov ntawv tseem ceeb

Muaj 3 tsab ntawv tseem ceeb

• server.py - Tsim Web Portal
• working.py - Logic rau Raspberry Pi 1 (Chaw Haujlwm)
• door.py Logic rau Raspberry Pi 2 (Qhov Rooj)

Peb tsuas yog siv tag nrho 3 tus lej kom tau txais qhov txiaj ntsig peb xav tau

Peb tuaj yeem tau txais nws los ntawm Google tsav hauv qab Main.zip
