Local autonomous data collection system

Lub tuam txhab yuav NEKST-M saib xyuas cov ntawv, tsim tawm hauv tsev los ntawm Next Technologies. Txhawm rau kom pom kev ua haujlwm ntawm cov twj tso kua mis,
hluav taws thiab kev ruaj ntseg tswb, voltage muaj nyob rau ntawm starters, chav tsev kub, dej kub thaum muaj xwm ceev. Lub plawv ntawm NEKST-M yog ATMEGA 1280 thiab qhov tseeb no txhawb kom muaj peev xwm tsim koj tus kheej cov khoom siv rau cov kev xav tau tshwj xeeb.

Txoj haujlwm tau teeb tsa los tsim kom muaj kev tswj hwm tus kheej hauv zos xa mus rau cov kev xav tau tshwj xeeb hauv lub sijhawm luv tshaj plaws thiab tus nqi tsawg. Lub hauv paus yog microcontroller. Kev tsim kho, tsim khoom, tsim los ntawm cov neeg ua haujlwm lawv tus kheej.

Lub kaw lus yuav tsum ua haujlwm yam tsis muaj kev vam khom ntawm cov xov tooj ntawm tes, cov servers, Internet thiab cov ntawv tso cai rau kev siv xov tooj cua ntau zaus, tsis txhob siv cov khoos phis tawj hauv kev ua haujlwm ntawm kev saib xyuas thiab tswj qhov system lossis, feem ntau, siv lub laptops ib ntus, tsis muaj kev nkag mus. cov khoom rau lub sijhawm ntev (6-9 lub hlis). Lub network configuration muaj cov qauv radial. Cov ntaub ntawv raug sau los ntawm ib qho chaw thiab tom qab ntawd xa mus rau kev ua haujlwm ntawm kev sib txuas lus tsis tu ncua lossis ua ib daim ntawv nyuaj.

Lub system yuav tsum muab:

• saib xyuas kev ua haujlwm ntawm cov twj tso kua mis
• tshuab automation
• tiv thaiv los ntawm qhov tshwm sim ntawm cov xwm txheej kub ntxhov
• ceeb toom xwm txheej ceev
• lub sijhawm ua haujlwm suav
• xam cov nqi hluav taws xob siv
• khoom tswj qhov kub thiab txias
• kev ruaj ntseg thiab hluav taws tswb
• periodic tej thaj chaw deb kaw cov ntaub ntawv
• tsis paub yav tom ntej yuav tsum tau

Cov xwm txheej ua haujlwm:

• thaj tsam 1 sq. km.
• ncaj visibility nruab nrab ntawm cov khoom
• kub ntawm +50 txog -50C
• Humidity mus txog 100%
• cov kab mob lom lom (pwm, sulfate-txo cov kab mob)
• Kev co, tsis muaj ntxiv, ntawm cov tshuab ntawm chav kawm 1-2 raws li GOST ISO 10816-1-97
• electromagnetic ib puag ncig - hloov hluav taws xob motors nrog KT 6053 contactors, RVS-DN muag khoom pib, SIEMENS MICROMASTER PID tswj cov cuab yeej, hluav taws xob hauv ISM thiab GSM ntau yam raws li qhov yuav tsum tau muaj rau cov khoom siv no, phau ntawv arc vuam ntawm qhov chaw
• Lub network voltage ntau dhau, cuam tshuam rau lub sijhawm luv luv hauv cov khoom siv hluav taws xob, xob laim overvoltages, theem tsis sib xws thaum cov kab hluav taws xob siv hluav taws xob tawg hauv 6-10 kV kev faib tawm.

Txawm hais tias cov kev cai nruj li no, kev siv tau yooj yim heev thaum daws qhov teeb meem ib kauj ruam.

Ua txhua yam rau hauv tus account, "Arduino Nano 3.0" pawg thawj coj los ua "lub hlwb" ntawm txoj kev npaj. Robotdyn board muaj ATMEGA 328 maub los, qhov tsim nyog 3,3V voltage stabilizer rau
Tam sim no 800 mA thiab converter rau CH340G UART-USB.

Ua ntej tshaj plaws, cov sijhawm ua haujlwm cov sijhawm ua haujlwm tau tsim los ua cov txheej txheem tshiab tshaj plaws. Yav dhau los siv cov ntsuas hluav taws xob sib sau ua ke ntawm PICs nrog lub tshuab hluav taws xob tsis muaj hluav taws xob tsis ua haujlwm vim qhov hluav taws xob nce siab hauv ib xyoos ntawm kev ua haujlwm. Tsuas yog cov kev sib txuas uas siv cov khoom siv hluav taws xob 5V hauv tsev tseem nyob tsis tau. Txhawm rau txhawm rau txhim kho thiab siv ntau yam ntawm kev sib txuas, lub teeb liab hais txog lub xeev ntawm cov units raug coj los ntawm cov terminals ntawm cov khoom siv hloov pauv, i.e. sau npe ntawm lub xub ntiag ntawm 1st theem voltage nrog peb-theem fais fab mov ntawm 380V. Txhawm rau koom tes nrog tus maub los, ib qho nruab nrab relay nrog 220V winding los yog optocoupler muaj li ntawm LED thiab GL5516 photoresistor lossis PC817 optocoupler yog siv. Tag nrho cov kev xaiv tau raug sim. Lub LED yog powered los ntawm ib tug rectified voltage nrog tam sim no txwv siv ob lub SVV22 capacitors tsim rau ib tug voltage ntawm 630V txuas nyob rau hauv series rau kev nyab xeeb thaum lub sij hawm tsis sib xws ntawm cov circuits nrog ib tug megohmmeter.
Kev nyeem ntawv lub sijhawm ua haujlwm nyeem siv ST7735S LCD npo, cov ntaub ntawv xa mus rau lub sijhawm ntawm xov tooj cua siv E01-ML01DP05 module ntawm zaus ntawm 2,4 MHz. Cov cuab yeej no muaj nRF24L01+ nti thiab RFX2401C xa / txais amplifier,
tso zis zog mus txog 100 mW. Helical kav hlau txais xov tsim rau qhov xav tau ntau yam hauv lub laij lej online thaj chaw. Qhov kev xaiv ntawm hom kav hlau txais xov yog txiav txim siab los ntawm kev tsis suav nrog kev txais tos ntawm singly reflected nthwv dej los ntawm ib puag ncig cov qauv hlau. Kav hlau txais xov qhov chaw yog luam tawm ntawm lub tshuab luam ntawv 3D. Lub xeev tam sim no ntawm cov txee yog khaws cia rau hauv EEPROM ntawm tus maub los nws tus kheej thiab tau rov qab los thaum muaj hluav taws xob poob qis. Lub sij hawm ncua sij hawm rau suav yog muab los ntawm RTC nti DS3231 nyob rau hauv daim ntawv ntawm ib tug module nrog ib tug thaub qab roj teeb. Lub hwj chim mov siv 3 modules, qhov tseeb mem tes qhov chaw 220/5V HLK-PM01 600mA, converter los ntawm 1-5V rau 5V HWV -553 и 03962A - roj teeb tswj nrog tswv yim tiv thaiv luv luv Circuit Court, overdischarge thiab overcharge. Tag nrho cov khoom tau yuav ntawm Aliexpress lub vev xaib.

EEPROM nco muaj tsawg kawg ntawm kev sau-nrawm mus, raws li cov chaw tsim khoom, 12 zaug. Qhov kev xaiv phem tshaj plaws yog thaum tsawg kawg ib lub xov tooj ntawm tes hloov kho tas li. Qhov ntim ntawm 100000 lub txee yog 1 bytes, qhov no yog tus lej ntev, 4 lub txee, tag nrho ntawm 4 bytes yog nyob ntawm ib cov ntaub ntawv. Qhov ntev ntawm lub nti nco yog 16 bytes; tom qab 1024 nkag ntawm 64 lub txee, kaw yuav pib dua. Hauv lub tsev qiv ntawv EEPROM, EEPROM.put txoj kev tsis sau; yog tias tus nqi ntawm lub xov tooj ntawm tes thiab cov ntaub ntawv raug sau sib tw, yuav tsis muaj kev puas tsuaj ntawm cov hlwb. Raws li qhov tshwm sim, lub sijhawm ua haujlwm tau lees paub yuav muaj ntau dua 4 xyoo. Lub sijhawm ua tau tab sis tsis lees paub ua haujlwm tuaj yeem ntev dua.
