KEV PAB CUAM

Lub Tsev Automation Card yuav tsum muaj 24VDC / AC tswj fais fab sab nraud. Lub hwj chim yog muab rau lub rooj tsavxwm los ntawm kev sib txuas rau sab xis nyob rau sab xis sab xis (saib BOARD LAYOUT ). Cov boards lees txais DC lossis AC lub zog. Yog tias siv lub zog DC, polarity tsis tseem ceeb. Ib lub zos 5V regulator muab txog li 3A lub zog rau Raspberry Pi, thiab 3.3V regulator powers lub digital circuits. Kev rho tawm DC-DC converters yog siv los ua hluav taws xob relays.

Peb pom zoo siv 24VDC / AC fais fab mov nkaus xwb
RAU POWER RASPBERRY PI CARD
Yog tias ntau Daim Npav Tsev Automation tau muab tso rau sab saum toj ntawm ib leeg, peb pom zoo kom siv ib qho 24VDC / AC fais fab mov rau lub zog tag nrho cov ntawv. Tus neeg siv yuav tsum faib cov cable thiab khiav cov xov hlau rau txhua daim npav.
Kev siv hluav taws xob:
• 50 mA @ + 24V

HARDWARE WATCHDOG

Lub Tsev Automation Card muaj cov cuab yeej ua haujlwm tsim kho uas yuav lav tias koj txoj haujlwm tseem ceeb yuav ua haujlwm ntxiv txawm tias Raspberry Pi software hangs. Tom qab fais fab tuag tus saib xyuas yog neeg xiam, thiab ua haujlwm tom qab nws tau txais thawj zaug rov pib dua.
Lub sijhawm ua haujlwm yog 120 vib nas this. Thaum ua haujlwm, yog tias nws tsis tau txais kev rov pib dua los ntawm Raspberry Pi hauv 2 feeb, tus saib xyuas txiav lub zog thiab rov ua dua tom qab 10 vib nas this.
Raspberry Pi yuav tsum tau muab cov lus txib rov pib dua ntawm I2C chaw nres nkoj ua ntej lub sij hawm ntawm tus saib xyuas tas sij hawm.
Lub sijhawm timer tom qab lub zog nce thiab lub sijhawm ua haujlwm timer tuaj yeem raug teeb tsa los ntawm kab hais kom ua. Tus naj npawb ntawm kev rov pib dua yog khaws cia hauv flash thiab tuaj yeem nkag mus lossis tshem tawm ntawm kab hais kom ua. Tag nrho cov lus txib saib xyuas tau piav qhia los ntawm kev pabcuam hauv online.

ANALOG INPUTS / OUTPUTS CALIBRATION

Tag nrho cov analog inputs thiab outputs yog calibrated ntawm lub Hoobkas, tab sis firmware commands tso cai rau tus neeg siv rov calibrate lub rooj tsavxwm, los yog calibrate nws kom zoo dua precision. Tag nrho cov inputs thiab outputs yog calibrated nyob rau hauv ob lub ntsiab lus; xaiv ob lub ntsiab lus kom ze rau qhov ua tau rau ob qhov kawg ntawm nplai. Txhawm rau calibrate cov inputs, tus neeg siv yuav tsum muab cov teeb liab analog. (Example: kom calibrate 0-10V inputs, tus neeg siv yuav tsum muab 10V adjustable fais fab mov). Txhawm rau calibrate cov zis, tus neeg siv yuav tsum tau muab cov lus txib los teeb tsa cov zis rau tus nqi uas xav tau, ntsuas qhov tshwm sim thiab muab cov lus txib calibration kom khaws tus nqi.
Cov txiaj ntsig tau muab khaws cia rau hauv flash thiab cov ntaub ntawv nkhaus yog suav tias yog linear. Yog tias ua yuam kev thaum lub sijhawm ntsuas ntsuas los ntawm kev ntaus cov lus txib tsis raug, RESET cov lus txib tuaj yeem siv los rov pib dua tag nrho cov channel hauv pawg sib txuas rau lub Hoobkas nqi. Tom qab RESET calibration tuaj yeem rov pib dua.
Lub rooj tsavxwm tuaj yeem ntsuas tau yam tsis muaj lub hauv paus ntawm cov teeb liab analog, los ntawm calibrating ua ntej cov outputs thiab ces routing lub calibrated outputs rau coj inputs. Cov lus txib hauv qab no muaj rau calibration:
