2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Tsis ntev los no kuv tau ua haujlwm ntawm kev nkag siab Microcontrollers thiab IOT raws cov cuab yeej rau Kev Tshawb Fawb Kev Ruaj Ntseg. Yog li, Kuv xav txog kev tsim lub tsev me me hauv tsev siv tshuab rau kev xyaum. Kuv tseem tsis tau ua tiav qhov no, tab sis rau kev pib kuv yuav sib qhia li cas kuv siv Raspberry Pi 2 thiab qee yam khoom siv hluav taws xob los tswj kuv chav chav teeb pom kev zoo hauv kab ntawv no. Tsis tas li, Kuv yuav tsis tham txog Kev teeb tsa thawj zaug rau Raspberry ntawm no, koj yuav pom ntau yam kev qhia rau qhov ntawd.

Tab sis hauv txoj haujlwm no, kuv yuav qhia cov khoom docker pi series no rau koj.

Khoom siv

Daim Ntawv Teev Npe:

• 1 x Raspberry Pi 3B+/3B/Xoom/Xoom W/4B/
• 1 x 16GB Class 10 TF card
• 1 x DockerPi series 4 Channel Relay Board (HAT)
• 1 x [email protected] fais fab mov uas yog los ntawm 52Pi
• 4 x Lub teeb sawb
• 1 x DC txuas
• 1 x 12V fais fab mov rau lub teeb ci.
• ob peb xaim.

Kauj Ruam 1: Paub Txog DockerPi Series 4 Channel Relay Board

DockerPi 4 Channel Relay yog tus tswv cuab ntawm DockerPi Series, feem ntau siv hauv IOT daim ntawv thov.

DockerPi 4 Channel Relay tuaj yeem xa AC/DC, hloov qhov hloov pauv ib txwm, kom ua tiav cov tswv yim ntau dua. DockerPi 4 Channel Relay tuaj yeem teeb tsa tau txog 4, thiab tuaj yeem teeb nrog lwm DockerPi nthuav tawm pawg thawj coj saib. Yog tias koj yuav tsum tau ua haujlwm ntev, peb kuj pom zoo kom koj siv peb DockerPi Lub Rooj Tswjhwm Saib lub zog kom nthuav dav zog ntxiv.

LUS CEEB TOOM Ua ntej peb mus txuas ntxiv Kuv xav ceeb toom koj txog qhov DANGER ntawm kev sim nrog "Mains Electricity". Yog dab tsi mus tsis raug qhov phem yuav ua rau tuag lossis tsawg kawg hlawv koj lub tsev. Yog li, thov TSIS TXHOB ua txhua yam uas tau hais hauv kab lus no yog tias koj tsis nkag siab tias koj tab tom ua dab tsi lossis ua kom zoo dua los ntawm kev pab ntawm qee tus kws paub txog hluav taws xob. Cia peb pib.

Kauj ruam 2: Nta

• DockerPi Series
• Programmable
• Tswj ncaj qha (tsis muaj lub cajmeem)
• Txuas ntxiv GPIO Pins
• 4 Channel Relay
• 4 Alt I2C Addr Support
• Relay Status Leds Support
• 3A 250V AC Txhawb
• 3A 30V DC
• Puas tuaj yeem sib tshooj nrog lwm pawg pawg Pawg ywj pheej ntawm cov cuab yeej tseem ceeb (xav tau kev txhawb nqa I2C)

Kauj Ruam 3: Daim Ntawv Qhia Chaw Nyob

Pawg thawj coj no muaj qhov chaw nyob sib cais, thiab koj tuaj yeem tswj hwm txhua qhov kev xa tawm los ntawm ib qho lus txib.

Lwm Yam Yuav Tsum Tau:

Kev nkag siab yooj yim ntawm Python lossis C lossis plhaub lossis Java lossis lwm yam lus (Kuv yuav siv C, nab hab sej, plhaub, thiab java)

• Kev nkag siab yooj yim ntawm Linux systems
• Kev Ntseeg Ntawm Lub Siab

Tam sim no, ua ntej yuav mus tom ntej koj yuav tsum nkag siab cov khoom siv hluav taws xob peb yuav siv:

1. Tshaj tawm:

Kev xa tawm yog cov cuab yeej hluav taws xob uas feem ntau siv los tswj cov hluav taws xob siab siv hluav taws xob qis heev raws li Kev Nkag Mus. Qhov no suav nrog cov hlua qhwv ib ncig ntawm tus ncej thiab ob lub hlau me me (cov nodes) uas tau siv los kaw qhov Circuit Court. Ib qho ntawm qhov tau tsau thiab lwm qhov yog txav tau. Thaum twg ib qho hluav taws xob dhau los ntawm lub kauj, nws tsim lub zog sib nqus thiab nyiam qhov txav ntawm lub node zoo li qub thiab lub Circuit Court tau ua tiav. Yog li, tsuas yog siv cov hluav taws xob me me los txhawb lub kauj peb tuaj yeem ua tiav qhov Circuit Court rau qhov hluav taws xob siab mus ncig. Tsis tas li, vim tias qhov zoo li qub tsis txuas nrog lub cev rau lub kauj muaj tsawg heev uas Microcontroller ua kom lub kauj tau puas yog tias muaj qee yam tsis raug.

Kauj Ruam 4: Txuas Txuas Txuas mus rau Tus Tuav Teeb Pom Kev Zoo los ntawm Cov Khoom Siv Hluav Taws Xob

Tam sim no mus rau qhov tsis yooj yim, Peb yuav txuas qhov txuas mus rau tus tuav lub teeb uas siv los ntawm Cov Hluav Taws Xob Hluav Taws Xob. Tab sis, ua ntej kuv xav qhia koj lub tswv yim luv luv txog yuav ua li cas lub teeb tau qhib thiab OFF ntawm cov khoom siv ncaj qha.

Tam sim no, thaum lub teeb pom kev zoo txuas nrog lub hauv paus tseem ceeb, peb feem ntau ua qhov no los ntawm kev txuas ob lub xov hlau rau lub teeb. ib qho ntawm cov xaim yog "Neutral" xaim thiab lwm qhov yog "Negative" xaim uas tau nqa tam sim no, tseem muaj qhov hloov pauv ntxiv rau tag nrho cov Circuit Court los tswj ON ON OFF mechanism. Yog li, thaum qhov kev sib txuas tau txuas (lossis Tig Tawm) tam sim no ntws los ntawm qhov muag teeb thiab xaim nruab nrab, ua kom tiav Circuit Court. Qhov no tig lub teeb taws ON. Thaum qhov kev hloov pauv ntawm nws, nws ua txhaum lub Circuit Court thiab lub teeb tig tawm OFF. Nov yog daim duab me me los piav qhia qhov no:

Tam sim no, rau peb qhov kev sim, peb yuav tsum ua kom "Cov Hlau Tsis Zoo" dhau los ntawm peb qhov kev sib txuas kom tawg lub Circuit Court thiab tswj lub zog ntws siv kev hloov pauv. Yog li, thaum qhov kev sib txuas yuav qhib rau, nws yuav tsum ua kom tiav lub Circuit Court thiab Lub Teeb yuav tsum tig rau thiab hloov pauv. Xa mus rau daim duab hauv qab no rau Full Circuit.

#txiav tawm 0x00

int main (tsis muaj dab tsi)

{

printf ("Qhib Relays hauv C / n");

koj fd;.

int kuv = 0;

fd = wiringPiI2CSetup (DEVICE_ADDR);

rau (;;) {

rau (kuv = 1; kuv <= 4; kuv ++)

{

printf ("Qhib rau kev xa xov No. $ d", i);

xaimPiI2CWriteReg8 (fd, i, ON);

tsaug zog (200);

printf ("Tua tawm tsis siv xov tooj. $ d", i);

xaimPiI2CWriteReg8 (fd, i, OFF);

tsaug zog (200);

}

}

rov 0;

}

Sau nws

gcc relay.c -lwiringPi -o relay

Exec Nws

./saib

Kauj Ruam 8: Qhov program hauv Python (Raspberry Pi)

Cov cai hauv qab no tau pom zoo kom ua tiav siv Python 3 thiab teeb tsa lub tsev qiv ntawv smbus:

Tsim cov ntaub ntawv npe nws: "relay.py" thiab muab cov lej hauv qab no:

ntshuam sij hawm li t

ntshuam smbus

ntshuam sys

DEVICE_BUS = 1

DEVICE_ADDR = 0x10

npav = smbus. SMBus (DEVICE_BUS)

thaum Muaj Tseeb:

sim:

rau kuv hauv ntau (1, 5):

bus.write_byte_data (DEVICE_ADDR, kuv, 0xFF)

t. pw tsaug zog (1)

bus.write_byte_data (DEVICE_ADDR, kuv, 0x00)

t. pw tsaug zog (1)

tshwj tsis yog KeyboardInterrupt li e:

print ("Qhib lub Loop")

sys.exit ()

* Txuag nws thiab tom qab ntawv ua sej 3:

python3 tso tawm.py
