2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

Hav cov menyuam rau tsev kawm ntawv Kuv xav tau lub tswv yim rau ib qhov project. Yog li kuv tau xav, nws yuav tsum yog qhov haujlwm nrog raspberry pi thiab nws yog hauv zos. Mam li nco dheev kuv muaj lub tswv yim zoo thiab tsis nug kuv li cas kuv tau txais lub tswv yim ntawd tab sis kuv xav txog kev hloov kho rau tus saib xyuas menyuam. Tsuas yog xav txog qhov thib ob txog lub tswv yim ntawd, cov menyuam saib feem ntau tsuas muaj lub luag haujlwm los mloog tus menyuam chav.

Cov yam ntxwv

• Lub teeb me me qhia nrog kho xim
• Lub koob yees duab uas qhia koj cov duab nyob
• Tus hais lus los ua suab paj nruag
• Sensors los ntes tus menyuam txav
• Txhua yam uas qhia ntawm lub vev xaib

Cov ntaub ntawv luv

Letme piav qhia qhov no hauv luv luv version. Yog li peb xav tau lub vev xaib thiab rau qhov haujlwm no kuv siv Flask, peb kuj xav tau lub hauv paus thiab kuv siv mysql, kuj yog tsab ntawv uas ua haujlwm kho vajtse thiab qhov no yog nrog nab hab sej (3) thiab thaum kawg peb xav tau teeb tsa server uas yuav yog nginx ntawm PI.

Peb xav tau dab tsi

• Lub Raspberry Pi 3
• Cov kauj ruam 28BYJ
• Tus tsav tsheb kauj vab ULN2003 stepper module
• Ib rgb coj nrog 3 tus tiv thaiv 330Ohm
• Pi NoIR lub koob yees duab V2
• Ultrasonic sensor HC-SR04
• Lub micro module los ntawm ardiuno
• MAX 98357 UA
• Tus neeg hais lus 8Ohm
• Thiab tsis txhob hnov qab yuav tus dais

Teeb raspberry pi ----------------------------------------------- ----------------------------------------------------------------------- ------------------------------ ua tsaug

Thaum xub thawj peb yuav tsum teeb tsa Pi. Pib twb nkag rau ntawm putty, yog tias koj tsis muaj putty Kuv xav kom koj rub tawm qhov no, tsuas yog ntaus koj tus ip zoo li qub ntawm Pi nrog ssh thiab koj mus nrog nws. Yog tias koj yuav tsum teeb tsa koj li Raspberry Pi ces kuv tau txais xov xwm tsis zoo, Kuv tsis piav qhia qhov no hauv qhov haujlwm no.

Nruab pob

sudo apt hloov tshiab

sudo apt install -y python3-venv python3-pip python3-mysqldb mysql-server uwsgi nginx uwsgi-plugin-python3

Ib puag ncig virtual

python3 -m pip nruab -hloov kho pip setuptools log virtualenv

mkdir {koj daim ntawv teev npe} && cd {koj qhov project foldname} python3 -m venv --system-site-packages env source env/bin/qhib cov nab npawb -m pip nruab mysql-connector-python argon2-cffi Flask Flask-HTTPAuth Flask- MySQL mysql-connector-python passlib

Tam sim no koj yuav tsum clone qhov chaw cia khoom git hauv koj daim ntawv tais ceev tseg

github.com/NMCT-S2-Project-I/Project-I.git

Yog tias koj saib hauv koj cov phiaj xwm phiaj xwm koj yuav tsum pom 5 daim nplaub tshev

• conf
• ua env
• sensor
• sql ua
• web

Database

sudo systemctl xwm txheej mysql

ss -lt | grep mysql sudo mysql

tsim ib tus neeg siv hauv database nrog txhua txoj cai thiab ua koj li database

tsim cov neeg siv 'neeg siv'@'localhost' txheeb xyuas los ntawm 'tus password';

tsim database yourdatabasename; muab tag nrho cov cai hauv koj li databasename.* rau 'user'@'localhost' nrog rau kev xaiv;

Conf files rau server

Hauv uwsgi-flask.ini koj hloov 'module = …' rau 'module = web: app' thiab txoj hauv kev rau koj lub virtualenv uas koj tau tsim. Hauv lwm cov ntaub ntawv koj yuav tsum hloov txoj hauv kev mus rau qhov tseeb ntawm txoj hauv kev ntawm koj phau ntawv teev npe.

Thaum koj xam pom qhov ntawd koj tuaj yeem teeb tsa cov ntawv hauv qhov chaw raug.

sudo cp conf/project1-*. service/etc/systemd/system/

sudo systemctl daemon-reload sudo systemctl pib project1-* sudo systemctl xwm txheej project1-*

tam sim no peb yuav tsum teeb qhov no muaj

sudo cp conf/nginx/etc/nginx/sites-available/project1

sudo rm/etc/nginx/sites-enabled/default sudo ln -s/etc/nginx/sites-available/project1/etc/nginx/sites-enabled/project1 sudo systemctl restart nginx.service sudo nginx -t

Yog tias txhua yam ua tau zoo koj yuav tsum nyob zoo nrog lub ntiaj teb nrog cov lus txib no

wget -qO - localhost

Ua tiav! Zoo, qhov ntawd yog rau ib feem kom tso cai rau koj ua haujlwm ntawm…

Kauj Ruam 1: Txuas Cov Khoom Kho Vajtse rau Pi

siv BCM

audio MAX 98357A

• HLB to GPIO 18
• Cov ntaub ntawv rau GPIO 21
• HLB to GPIO 19

lub teeb

• liab rau GPIO 17
• ntsuab rau GPIO 27
• xiav rau GPIO 22

lub cev muaj zog module ULN2003

• pin 1 to GPIO 5
• pin 2 to GPIO 6
• pin 3 to GPIO 13
• pin 4 to GPIO 26

me me

D0 rau GPIO 21

ultrasonic qib sensor

• xa mus rau GPIO 16
• ncha mus rau GPIO 20

Kauj Ruam 2: Coding Cov Txheej Txheem Tseem Ceeb

Kuv tsis nkag mus rau cov ntsiab lus ntawm no tab sis koj tuaj yeem txheeb xyuas kuv tus lej hauv github.

Txhawm rau pib nrog kuv tau ua kuv li html thiab css, qhov ntsuas, nkag mus, sau npe, tshuaj ntsuam hauv tsev, nkauj, ntxiv nkauj, ntxiv suab, teeb, lub koob yees duab, teeb tsa lub koob yees duab, sensor, nplooj ntawv dashboard. Cov ntaub ntawv html yuav tsum muaj nyob hauv tus qauv thiab cov ntaub ntawv css hauv cov ntawv zoo li qub/css. Koj tuaj yeem hloov kho tus css zoo li koj xav tau.

Yog tias koj ua tiav ntu no koj yuav tsum teeb tsa koj lub hwj. Flask yog ib qho yooj yim siv tsuas yog piv txwv ntawm lub ntiaj teb nyob zoo

# ntshuam hwj chim thaum xub thawj

los ntawm cov raj ntshuam * @app.route ('/') def index (): rov render_template ('index.html')

Tam sim no hauv kuv tus lej qhov no twb tau ua tiav lawm, tsuas yog qhov koj yuav tsum tau ua yog hloov cov neeg siv database thiab tus lej zais rau qhov ntawd los ntawm koj thiab ofcourse ua tib lub database uas koj kuj tuaj yeem pom hauv github.

Kauj Ruam 3: Tsim Database

Txog cov kiv cua tiag tiag kuv yuav qhia koj li cas los tsim tib cov ntaub ntawv.

Yog li ua ntej peb yuav tsum tsim cov ntaub ntawv yog tias koj tsis nyob hauv qib ib.

tsim database beargardian;

Thaum koj ua qhov no koj tsim cov ntxhuav hauv mysql workbench lossis phpadmin

cov neeg siv lub rooj muaj

• userID
• thawj lub npe
• lub xeem
• email
• npe menyuam yaus
• password nrog sha1
• userfolder
• playmusic (int)
• teeb pom kev zoo (int)
• playrecording (int) cov

music table muaj

• musicID
• nkauj
• txoj kev
• userfolder
• xwm txheej
• ntim

kaw lub rooj muaj

• kaw ID
• txoj kev
• userfolder
• sij hawm
• hnub

cov lus xim muaj

• colorID
• liab
• ntsuab
• xiav
• ci ntsa iab
• userID

dais rooj muaj

• bearID (zauv (8))
• userID default null
• bearname

sensor rooj muaj

• sensorID
• nrug deb
• me me
• bearID
• sij hawm
• hnub
• pw tsaug zog

Yog li tam sim no koj tau tsim cov ntaub ntawv ua tiav, cia peb mus rau kho vajtse.

Kauj ruam 4: Khoos phis tawj khoos phis tawj

Kuv yuav tau qhia me ntsis ntawm cov cai thiab qhia koj vim li cas kuv thiaj ua li ntawd.

Txhawm rau pib nrog kuv siv xov xov, dab tsi yuav tsum yog nyob hauv txoj haujlwm no. Dab tsi yog xov, hmmm cov lus nug zoo! Zoo hem nyob hauv nab hab sej yog kom ua haujlwm ntau lub program ib zaug. Yog li yog koj piv txwv hloov xim koj tuaj yeem sau tseg. Nws yooj yim siv tsis txhob txhawj.

ntshuam _threaddef function_name (ib yam, ib yam dab tsi_else): chaws kom khiav

_thread.start_new_thread (function_name, tuple_with_the_functions_variables)

Yog tias koj saib kuv qhov program koj pom logger.info ('…'). Nov yog qhov ua haujlwm luam tawm tab sis zoo dua, vim ntawm Pi koj tsis tuaj yeem luam cov khoom tawm yog li kuv ua cov ntawv thiab luam tawm hauv ntawd. Yoe tuaj yeem teev cov ntaub ntawv teev cia nrog tus lej no.

logger = logging.getLogger (_ npe _) logger.setLevel (logging. INFO) # tsim cov ntaub ntawv tus tuav tuav = logging. FileHandler ('logger.log') handler.setLevel (logging. INFO)

# tsim cov ntawv teev npe

formatter = logging. Formatter (' %(asctime) s - %(name) s - %(message) s') handler.setFormatter (formatter)

# ntxiv cov neeg lis haujlwm rau lub cav ntoo

logger.addHandler (tus tuav tes)

logger.info ('pib kho vajtse / n ---------------------------------------')

ntxiv hauv txoj cai nws tus kheej kuv piav txhua yam.
