Singalinganisa kanjani into engabonakali, exutshwe nento esingenakukwazi ukuphila ngaphandle kwayo? Lo mbuzo uphakathi kokuphatha umthombo wethu oyigugu kakhulu: amanzi. Ukuze ngithole impendulo, ngibheke incwadi yezobuchwepheshe yethuluzi elithile, inzwa ye-RD-WDCO2, elinganisa i-carbon dioxide encibilikisiwe. Engikutholile kwakungelona uhlu lwemininingwane kodwa indaba yobunjiniyela obuhlakaniphile kanye nobunzima obufihliwe. Lesi sihloko sinikeza ezinye zezinto ezitholwe ngendlela emangalisayo nehlaba umxhwele kakhulu eziqukethwe kuleyo ncwadi yemiyalelo, okubonisa ukuthi kudinga ubuhlakani obungakanani ukuqapha indawo yonke engabonakali equkethwe yiconsi elilodwa lamanzi.
Le sensor “ibona” i-CO2 ngokukhanya kwe-infrared.
Esikhundleni sokusabela kwamakhemikhali noma i-probe ebonakalayo, le sensor isebenzisa indlela yokubona ekhangayo. UManual uthi ubuchwepheshe babo "busekelwe kusimiso sokumuncwa kwe-infrared ye-NDIR," ngakho-ke kusho ukuthi basebenzisa ukukhanya kwe-infrared okungasabalalisi ukuthola ukuthi kukhona yini ama-molecule e-CO2 azungezile.
Ukuze kufinyelelwe izinga elinjalo lokunemba, idinga ukukhipha uhlobo lokukhanya oluyinkimbinkimbi kakhulu. Ine-"optical cavity enelungelo lobunikazi, umthombo wokukhanya ongenisiwe kanye ne-dual-channel detector." Lolu hlobo lokusetha lungakwazi "ukubona isinxephezelo sokubhekisela kwezindlela ezimbili ze-optical emkhathini," okusho ukuthi inzwa ingazigcina ilinganisiwe njalo futhi inikeze ukufundwa okulungile ngaso sonke isikhathi, kungaxhomeki ekutheni ingakanani i-oxygen ekhona. Futhi umphumela muhle kakhulu: ukunemba kungu-±(20PPM+5% ukufunda), kanti isikhathi sokuphendula singaphansi kwemizuzwana engama-20. Impendulo enhle: ukusebenzisa umbala othile wokukhanya ukubala inani lama-molecule egesi angenambala ancibilikiswe emanzini.
1. Kuyamangalisa ukuthi kuqinile futhi kwenzelwe imisebenzi engcolile.
Nakuba iyithuluzi lokukhanya lobuchwepheshe obuphezulu, i-RD-WDCO2 yenzelwe umhlaba wangempela. Ikhuluma "ngokwakhiwa kwayo okungajwayelekile okungangeni manzi" okungahlukaniswa futhi kuhlanzwe kalula. Ukulungiswa okusebenzayo kubalulekile kudivayisi engafakwa emathangini epulazi lezinhlanzi noma ukuhlola amanzi agelezayo.
Ilinganiswe ngokusemthethweni nge-IP68, okusho ukuthi ivikeleke kakhulu othulini futhi ingacwiliswa emanzini isikhathi eside. Futhi kuwubufakazi obengeziwe bokuthi lokhu kunamandla kangakanani ngoba kungasebenza kuzo zonke izinhlobo zokushisa ezahlukene, kusukela ekubandeni okungaphansi kwama-degrees angu-20 kuya ekushiseni okungaphezulu kwama-degrees Celsius angu-60, ngakho-ke kungaba kuhle emfudlaneni obandayo noma ethangini lezimboni elifudumele. Ifilosofi yokuklama ichazwe kahle ngumugqa ovela encwadini yemiyalelo.
Igobolondo lilula futhi kulula ukulifaka endaweni.
Futhi ihlanganisa uhlelo lwangaphakathi olubucayi nengaphandle eliqinile okulula ukuthi abantu balisebenzise. Lokhu kusho ukuthi bayazi ukuthi kungaba nzima kangakanani ezindaweni lapho lolu hlobo lolwazi lubaluleke kakhulu khona - njengamapulazi ezinhlanzi noma ukubuka imvelo.
2. Kulinganisa okungaphezu nje kwalokho okusemanzini.
Into ephikisana kakhulu engiyitholile ukuthi i-“Water Dissolved CO2 sensor” ingasebenza nanoma yini enye ngaphandle kwamanzi. Kuvela ukuthi incwadi yemiyalelo ikhombisa ukuthi inamandla amahle okusebenza kabili okwenza ibe usizo kakhulu kunalokho okubizwa ngakho.
Ngokusho komthombo, i-RD-WDCO2 ingasetshenziswa ukukala inani le-CO2 encibilikisiwe emanzini, futhi ingasetshenziswa nokuqapha izinga le-CO2 ezimweni ezishisayo nezinomswakama.
Futhi lokhu kuguquguquka kwenza kube ithuluzi eliwusizo kuzo zonke izinhlobo zezindawo ezahlukene. Lingasetshenziswa njengoba kuhloswe ngalo "Ukufuywa Kwezinhlanzi" kanye "Nokuqapha Ikhwalithi Yamanzi", kodwa futhi lihle kakhulu "Nokuqapha Imvelo Yezindawo Zokugcina Izitshalo Zezolimo" ngoba umswakama ophezulu ungenza kube nzima kwezinye izinhlobo zezinzwa ze-CO2.
4. Ixhumana ngolimi lwedijithali oluyinkimbinkimbi
Inzwa ayisebenzi uma ingakwazi ukwabelana ngalokho ekutholile. I-RD-WDCO2 ayibonisi nje inombolo, ikhuluma nemishini ehlukene ngokusebenzisa izinhlobo eziningi zezingxoxo zekhompyutha (izilimi zedijithali) ukuze ikwazi ukutshela amanye amadivayisi ukuthi ingakanani i-CO2. Isekela ububanzi bezimpawu zokukhipha kanye nezinqubo ezifana ne-RS485, i-UART, i-IIC.
Lona akuwona umlayezo wombhalo ojwayelekile. Ukuze uthole ukufundwa ngephrothokholi ejwayelekile ye-MODBUS nge-RS485, ikhompyutha kufanele idlulise umucu womyalo othize ngefomethi ye-hexadecimal. Isibonelo, ukuze icele inzwa #32 ukuthi ifunde i-CO2 yamanje, i-host ingathumela lo mlayezo onekhodi:
20 03 00 00 00 01 82 BB
Futhi inzwa izophendula ngomyalezo wayo oyimfihlakalo onolwazi oludingekayo:
20 03 02 01 AB 44 6C
Kule mpendulo, ulwazi olubalulekile luyi-01AB. Lokhu ukuhlushwa kwe-CO2 ngesimo se-hex, okulingana no-427ppm ngamadesimali. Lezi zingxoxo ezithule neziyimfihlo ziwukuxhumana okuyinhloko phakathi komhlaba osizungezile namakhompyutha awuqaphayo, okushintsha izinombolo ezilula kusuka ezinzwa zibe ulwazi oluwusizo esingalusebenzisa.
Isiphetho: Ubuhlakani Obufihliwe Kubuchwepheshe Bansuku Zonke
Ukubheka ngokujulile incwadi yemiyalelo yobuchwepheshe kukhombisa ukuthi ngisho nalokho okubonakala kuyidivayisi encane kuyimangaliso yezinhlobo eziningi ezahlukene zobunjiniyela. Inzwa eyodwa ene-optics ephezulu yokubona igesi engabonakali, umklamo oqinile womzimba wokubekezelela izimo ezinzima, kanye nemithetho yedijithali eyinkimbinkimbi yokwabelana ngalokho ekutholayo. Kuyisikhumbuzo esinamandla sokuthi ngemuva kwayo yonke idatha egijima emhlabeni wethu, kunezixazululo zobuchwepheshe ezinhle neziqinile.
Futhi lokho kukwenza ucabange: yiziphi ezinye lezi zixhobo ezingabonakali ezibamba ngokungabonakali, zilawula izinhlelo esithembele kuzo ngaphandle kokuthi thina sazi?
Singaphinde sinikeze izixazululo ezahlukahlukene ze
1. Imitha ephathwayo yekhwalithi yamanzi enamapharamitha amaningi
2. Uhlelo lwe-Floating Buoy lwekhwalithi yamanzi enamapharamitha amaningi
3. Ibhulashi lokuhlanza elizenzakalelayo lenzwa yamanzi enamapharamitha amaningi
4. Isethi ephelele yamaseva kanye nemodyuli engenantambo yesofthiwe, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
