Uhlelo lokuqoqa idatha oluzimele

Inkampani ithenge izikhala zokuqapha ze-NEKST-M, ezikhiqizwe ngaphakathi yi-Next Technologies. Ukuqinisekisa ukubonwa kokusebenza kwamayunithi okupompa,
ama-alamu omlilo nezokuphepha, ukuba khona kwamandla kagesi ekuqaleni, izinga lokushisa legumbi, izinga lamanzi eliphuthumayo. Inhliziyo ye-NEKST-M yi-ATMEGA 1280 futhi leli qiniso liyakhuthaza ngokuya nokwenzeka kokudala ikhithi yakho yezidingo ezithile.

Umsebenzi wawusethelwe ukudala uhlelo lokuthunyelwa kwendawo oluzimele ngokugcwele lwezidingo ezithile ngesikhathi esifushane ngangokunokwenzeka nangezindleko ezincane. Isisekelo siyi-microcontroller. Ukuthuthukiswa, ukukhiqiza, okudalwe ngabasebenzi ngokwabo.

Uhlelo kumele lusebenze ngaphandle kokuncika kumanethiwekhi amaselula, amaseva, i-inthanethi kanye nohlelo lwamalayisense okusetshenziswa kwezinsiza zomsakazo, lungasebenzisi amakhompyutha ekusebenzeni kohlelo lokuqapha nokulawula noma, ikakhulukazi, lusebenzise amakhompyutha aphathekayo ngezikhathi ezithile, ngaphandle kokufinyelela izinto isikhathi eside (6-9 izinyanga). Ukumiswa kwenethiwekhi kunokwakheka kweradial. Idatha iqoqwa ngesikhathi esisodwa bese ithunyelwa ukuthi icutshungulwe ngamashaneli okuxhumana avamile noma njengekhophi ephepheni.

Isistimu kufanele ihlinzeke:

  • ukuqapha ukusebenza kwamayunithi okumpompa
  • i-automation yezobuchwepheshe
  • ukuvikelwa emiphumeleni yezimo eziphuthumayo
  • ukusayina kwesimo esiphuthumayo
  • isikhathi sokusebenza sokubala
  • ukubala inani likagesi osetshenzisiwe
  • ukulawula izinga lokushisa kwemishini
  • ukuphepha kanye ne-alamu yomlilo
  • ukuqoshwa okukude ngezikhathi ezithile kolwazi
  • izimfuneko zesikhathi esizayo ezingaziwa

Izimo zokusebenza:

  • indawo yokuhlanganisa 1 sq. km.
  • ukubonakala okuqondile phakathi kwezinto
  • lokushisa kusuka +50 kuya -50 C
  • umswakama kufika ku-100%
  • ama-biologically active deposits (isikhunta, amagciwane anciphisa i-sulfate)
  • ukudlidliza, akusekho, kwemishini yamakilasi 1-2 ngokuya ngeGOST ISO 10816-1-97
  • imvelo kagesi - ukushintsha kwamamotho kagesi ane-KT 6053 contactors, i-RVS-DN into yokuqala ethambile, imishini yokulawula ye-SIEMENS MICROMASTER PID, imisebe ebangeni le-ISM ne-GSM ngokuya ngezidingo zalawa madivayisi, ukushiselwa kwe-arc manual esizeni
  • I-voltage yenethiwekhi eyeqile, ukuphazamiseka kwesikhathi esifushane ekunikezeni ugesi, ukugcwala kombani, ukungalingani kwesigaba lapho intambo yolayini ongaphezulu inqamuka kumanethiwekhi okusabalalisa angu-6-10 kV.

Naphezu kwezidingo eziqinile ezinjalo, ukusebenzisa kulula kakhulu lapho uxazulula inkinga isinyathelo ngesinyathelo.

Ngokucabangela konke, ibhodi elithi "Arduino Nano 3.0" laba "ubuchopho" bohlelo. Ibhodi le-robotdyn linesilawuli se-ATMEGA 328, i-3,3V voltage stabilizer edingekayo
yamanje 800 mA futhi converter ukuze CH340G UART-USB.

Okokuqala nje, izibali zamahora okusebenza zadalwa njengalezo ezakamuva kakhulu. Amamitha ezimboni ayesetshenziswa ngaphambilini ahlanganiswe kuma-PIC anesekhethi yokuphakelwa kukagesi engena-transformer ahlulekile ngenxa yokwenyuka kwamandla kagesi phakathi nonyaka esebenza. Yilabo kuphela abaxhunywe kusetshenziswa izinsiza zikagesi ezenziwe ekhaya eziyi-5V ezihlale zinjalo. Ukusheshisa ukufakwa nokuhlukahluka kokuxhumeka, isignali mayelana nesimo samayunithi sithathwa kumatheminali amadivaysi okushintsha, i.e. ukubhaliswa kokuba khona kwe-voltage yesigaba soku-1 ngamandla wesigaba sesithathu se-380V. Ukuze uxhumanise nesilawuli, i-relay emaphakathi ene-220V yokujikajika noma i-optocoupler eyakhiwe i-LED kanye ne-GL5516 photoresistor noma i-PC817 optocoupler isetshenziswa. Zonke izinketho zahlolwa. I-LED inikwa amandla amandla kagesi alungisiwe anomkhawulo wamanje kusetshenziswa ama-capacitor amabili e-SVV22 adizayinelwe amandla kagesi angu-630V axhunywe ochungechungeni ukuze aphephe ngesikhathi sokuhlolwa ngephutha kwamasekhethi nge-megohmmeter.
Ukufunda ukufundwa kwesikhathi sokusebenza kusetshenziswa isikrini se-LCD se-ST7735S, ukudluliswa kwedatha yesikhathi sangempela ngomsakazo kusetshenziswa imojula ye-E01-ML01DP05 kumafrikhwensi angu-2,4 MHz. Le divayisi iqukethe i-nRF24L01+ chip kanye ne-RFX2401C transmit/receive amplifier,
amandla okukhipha afika ku-100 mW. Ama-antenna angama-Helical aklanyelwe uhla olufunekayo kusibali sokubala esiku-inthanethi isiza. Ukukhethwa kohlobo lwe-antenna kunqunywa ukungafakwa kokwamukelwa kwamagagasi aboniswa ngawodwa ezakhiweni zensimbi ezizungezile. Izingxenye ze-antenna ziphrintwa kuphrinta ye-3D. Isimo samanje sezinto zokubala sigcinwa ku-EEPROM yesilawuli ngokwaso futhi sibuyiselwa esimweni sokunqamuka kwamandla okungalindelekile. Izikhawu zesikhathi zokubala zihlinzekwa yi-RTC chip DS3231 ngendlela yemojuli enebhethri eliyisipele. Ukunikezwa kwamandla kusebenzisa amamojula ama-3, umthombo wangempela we-pulse 220/5V HLK-PM01 600mA, isiguquli esisuka ku-1-5V siye ku-5V I-HW-553 и 03962A - isilawuli sebhethri nge uhlelo ukuvikelwa ekujikelezeni okufushane, ukuchithwa ngokweqile kanye nokukhokhiswa ngokweqile. Zonke izingxenye zathengwa kuwebhusayithi ye-Aliexpress.

Ibhodi lesinkwaUhlelo lokuqoqa idatha oluzimele
4-channel counter. Kukhona izihlungi ze-LC kokokufaka ukuze kuvikelwe ekuphazamisekeni kolayini wokuxhumana ngababili osontekile. Idatha yesimo sokulawula izinto ihlale ifundwa kanye ngomzuzwana futhi iboniswa ngombala ku-LCD. Ukufundwa kuyabuyekezwa futhi kurekhodwe kumemori engaguquguquki njalo ngemizuzwana engama-1. Imizuzwana engu-36 ingu-36/1 wehora, lena ifomethi lapho idatha idingeka khona. Njalo ngemizuzwana eyi-100. ulwazi ludluliselwa mayelana nenani lamasekhondi okusebenza kweyunithi ngayinye yokulawula. Inkumbulo ye-EEPROM inenani elilinganiselwe lemijikelezo yokusula ukubhala, ngokomkhiqizi, izikhathi ezingu-12. Inketho embi kakhulu yilapho okungenani iseli elilodwa livuselelwa njalo. Ivolumu yekhawunta yoku-100000 ingamabhayithi angu-1, lena inombolo yefomethi ende, izinto zokubala ezingu-4, inani lamabhayithi angu-4 lihlala irekhodi elilodwa. Ubude bememori ye-chip bungamabhayithi angu-16; ngemva kokufakwa okungu-1024 kwezibali ezi-64, ukurekhoda kuzoqala phansi. Kulabhulali ye-EEPROM, indlela ye-EEPROM.put ayibhali; uma inani leseli kanye nolwazi olubhalwayo kufana, ngeke kube khona ukuwohloka kwamaseli. Ngenxa yalokho, isikhathi sokusebenza kwenkumbulo esiqinisekisiwe sizoba ngaphezu kweminyaka engu-4. Isikhathi somsebenzi ongenzeka kodwa ongaqinisekisiwe singaba yinde kakhulu.
