Njengoko uluntu kunye nokuphuculwa kwemizi-mveliso kuqhubeka, umba wokunqongophala kwamanzi uya usiba mandundu.Ukuphucula iinkqubo zokucocwa kwamanzi amdaka ezidolophini kunye nokufikelela kulawulo oluzenzekelayo kunobaluleko obunzulu bethiyori kunye nexabiso elibonakalayo ekwandiseni impumelelo yokucocwa kwamanzi amdaka.Le nkqubela phambili inceda ekongeni iindleko kunye nokuphucula umgangatho wokusingqongileyo.
1.Inkqubo yokucoca amanzi amdaka
Inkqubo yokucocwa kwamanzi amdaka ibandakanya unyango lwangaphambili, unyango lwebhayoloji, kunye nonyango olukwinqanaba eliphezulu.Kuphuculo kunye nokuhlaziywa kwezixhobo zokucocwa kwamanzi amdaka, ukuveliswa kweteknoloji kubalulekile.Inguqu kunye nophuculo lweshishini luxhomekeke kakhulu kwisiqinisekiso kunye nenkxaso yobuchwepheshe obutsha kunye nenkqubela phambili yobuchwepheshe obuphezulu.
2.ISifundo Sentsimi
I-ODOT C-Series Remote IO isetyenziswa kwindawo yokucoca amanzi amdaka kwisixeko esikwiPhondo laseSichuan, eChina, ngolu hlobo lulandelayo:
Indawo yokucoca amanzi amdaka isebenzisa i-Siemens S7-1500 njengeyona PLC iphambili, ekwigumbi lolawulo eliphakathi.Utshintsho lwe-ODOT ES-Series lwakha iqonga lomnatha womnatha, usebenzisa iimodyuli ze-CN-8032-L njengezikhululo ezikude kumacandelo ahlukeneyo enkqubo.Ezi modyuli ziququzelela ukuqokelelwa kwedatha kunye nolawulo ngaphakathi kwecandelo lenkqubo nganye nge-IO.Idatha eqokelelweyo igqithiselwa kwi-PLC yolawulo oluphakathi ngokutshintsha kwenethiwekhi yeringi.
Amacandelo enkqubo abandakanya:
(1) Icandelo lonyango lwangaphambili: Eli candelo liquka imodyuli ye-CN-8032-L njengesikhululo esikude.Ilawula izikrini ezirhabaxa nezicolekileyo, kunye namatanki okumisa umoya.Ulawulo olukude lokumisa izikrini lufezekiswa ngeemodyuli ze-CT-121F kunye ne-CT-222F.Itanki yokumisa i-aeration, ebonelelwa ngumenzi wesixhobo, ifaka i-485 interface exhasa iprotocol ye-Modbus RTU eqhelekileyo.Ukubeka iliso kunye nonxibelelwano kunye netanki yokumisa i-aeration iphunyezwa ngemodyuli ye-CT-5321 ukuqinisekisa ukuba imisebenzi elungelelanisiweyo kunye nefuthe kunye nezikrini.
(2) Icandelo eloNgezelelweyo loMthombo weKhabhoni: Ukuqinisekisa ukuthotyelwa kwemigangatho yokukhupha initrogen iyonke, eli candelo limisela ngokuzenzekelayo ulwelo lwamayeza ngokuqesha iimitha zokuhamba ezininzi kunye neevalvu zokutshintsha.Ngokufana necandelo lonyango lwangaphambili, isikhululo sisebenzisa i-CN-8032-L njengesikhululo esikude.I-CT-121F kunye ne-CT-222F iimodyuli zokulawula iivalvu zokutshintsha.Isango le-PNM02 V2.0 liqokelela idatha ekhawulezileyo kunye neyongezelekayo yokuhamba kwedatha ukusuka kwimitha ye-flow esibhozo kwindawo, idlulisela ngokuthe ngqo kwi-PLC emva kokuhlanganiswa kwinethiwekhi yendandatho.
(3) I-Biological Tank / Second Sedimentation Tank: Ezi nkqubo zimbini zabelana ngesikhululo esikude esinemodyuli ye-CN-8032-L.I-Mounted CT-121F, i-CT-222F, i-CT-3238, kunye ne-CT-4234 izixhobo zokulawula iimodyuli ezifana ne-agitators ephantsi kwamanzi, iipompo ze-reflux zangaphakathi kunye nezangaphandle kwi-tank ye-biological, i-sludge scraping machines, kunye neepompo ze-reflux kwi-tank ye-sedimentation yesibini.Ubuninzi bempompo yodaka olushiyekileyo lufuna ulawulo olusekwe kwimfuneko yekhefu le-de-mud;ngoko ke, ulawulo lwamaza ohlukeneyo luyamkelwa.Imodyuli ye-CT-3238 iqokelela izibonakaliso zangoku kwi-converter frequency, ngelixa i-CT-4234 imodyuli ikhupha iimpawu ze-4-20mA ukulawula ukuphindaphinda, ukuququzelela ukubeka iliso kwexesha langempela le-ORP, i-oksijini echithwe, kunye nedatha yomgangatho wamanzi.
(4) I-PAC Dosing Section: Ngokufana necandelo lokongeza umthombo wekhabhoni, le ndawo iquka i-CN-8032-L njengesikhululo esikude.Ilawula uqwalaselo oluzenzekelayo lolwelo lweyeza ngokulawula iivalvu zokutshintsha kunye nokubeka iliso kumaxabiso emitha yokuqukuqela.
(5) I-Fiber Filter Pool: Ukusebenzisa inkqubo yokulawula eyahlukileyo yonyango oluphezulu lwamanzi amdaka, i-Siemens S7-1200 isebenza njengesixhobo esiphambili sokulawula.Iiseti ezintandathu zamachibi okucoca zilawulwa zizikhululo ezintandathu ze-CN-8032-L, ngabanye.Ezi zikhululo zilawula iinkqubo ze-pool pool kunye nokunxibelelana kwedatha kunye ne-central 1500 PLC ngonxibelelwano lwe-S7.
Ukongeza, kukho amacandelo enkqubo exhasayo anje ngegumbi lokuvuthela, izixhobo zokukhupha udaka, izixhobo zokukhupha ivumba, kunye nokubeka iliso kwi-intanethi.
3. Gqibezela Intshayelelo Yesisombululo
Igumbi lokuvuthela lisebenzisa isethi epheleleyo yabalandeli ababonelelwe ngumenzi wezixhobo, exhasa i-modbus-RTU yonxibelelwano protocol.Ngenxa yomthamo wedatha ebanzi evela kubalandeli, ukusebenzisa i-CT-5321 slots kuthintelwe.Ke ngoko, kwidatha yabalandeli kule projekthi, isango le-PNM02 liqeshelwe ukuqokelela idatha.Iqokelela idatha ukusuka kwiiseti ezintlanu zabalandeli, ukudibanisa ukuqokelela idatha ngesango elilodwa kunye nokudibanisa kwinethiwekhi.
Isixhobo sokubeka iliso kwi-intanethi yokungena kunye nokuphuma kwamanzi sinika kuphela iseti enye ye-485 yojongano lwezixhobo zonxibelelwano.Nangona kunjalo, kufuneka iqokelelwe ngaxeshanye yikhompyuter ye-host kunye ne-terminal ye-DTU.Kulapho isango lethu le-ODOT-S4E2 lingena khona.Isango libonelela ngezibuko ezine ezizimeleyo ezizimeleyo.Uthotho lwezibuko loku-1 lucwangciswe njengesikhululo sokuqokelela idatha kwindawo yokungena nokuphuma esweni yamanzi.Uthotho lwezibuko 2 lisebenza njengesikhululo esisezantsi esibonelela ngedatha yesixhobo seDTU ukuba sifunde.Kwangaxeshanye, isango linikezela ngeprotocol ye-Modbus TCP eguquliweyo yekhompyuter ebamba ukubuyisa idatha.
Ngokwamkela iinkqubo zokucocwa kwamanzi amdaka akumgangatho ophezulu kunye nobuchwepheshe bolawulo oluzenzekelayo, indawo yokucocwa kwamanzi amdaka ifezekise imisebenzi esebenzayo, ezinzileyo, kunye nengenabungozi kokusingqongileyo.I-ODOT Remote IO ibonelele ngenkxaso eyomeleleyo yokuphucula nokulungiswa komzi-mveliso.Kwangaxeshanye, ngokusungula izinto ezintsha zobuchwepheshe kunye nokuguqulwa koshishino, indawo yokucocwa kwamanzi amdaka yenze impumelelo ebalulekileyo ekuphuculeni ukusebenza kakuhle kokucocwa kwamanzi amdaka, ukonga iindleko, kunye nokuphucula umgangatho wokusingqongileyo.
Kuphelele apho kolu hlelo lwe #ODOTBlog.Sijonge phambili kukwabelana kwethu okulandelayo!
