Singayilinganisa njani into engabonakaliyo, exutywe nento esingenakukwazi ukuphila ngaphandle kwayo? Lo mbuzo uphambili ekuphatheni ubutyebi bethu obuxabisekileyo: amanzi. Ukuze ndifumane impendulo, ndijonge incwadi yesikhokelo yesixhobo esithile, i-RD-WDCO2 sensor, elinganisa i-carbon dioxide enyibilikisiweyo. Endikufumeneyo yayingeloluhlu lweenkcukacha kodwa yibali lobunjineli obukrelekrele kunye nobunzima obufihlakeleyo. Eli nqaku libonisa ezinye zezona zinto zimangalisayo nezimangalisayo ezifumaneka kuloo ncwadi yesikhokelo, zibonisa indlela enobuchule ngayo ukugcina unonophelo lwendalo yonke engabonakaliyo ekwithontsi elinye lamanzi.
Le sensor "ibona" i-CO2 ngokukhanya kwe-infrared.
Endaweni ye-chemical reaction okanye i-physical probe, le sensor isebenzisa indlela yokukhanya emangalisayo. UManual uthi ubuchwepheshe babo "busekelwe kumgaqo we-NDIR infrared absorption," ngoko ke kuthetha ukuba basebenzisa ukukhanya kwe-infrared okungasasazekiyo ukufumanisa ukuba kukho iimolekyuli ze-CO2 ezikufutshane.
Ukuze ifikelele kwinqanaba elinjalo lokuchaneka, kufuneka ikhuphe uhlobo lokukhanya oluntsonkothileyo. Ine-"optical cavity enelungelo lobunikazi, umthombo wokukhanya ongeniswe ngaphakathi kunye ne-dual-channel detector." Olu hlobo lokuseta luno "kuqonda imbuyekezo yereferensi yeendlela ezimbini ze-optical esibhakabhakeni," oko kuthetha ukuba i-sensor inokuhlala ilungelelaniswe kwaye inike ukufundwa okuchanekileyo ngalo lonke ixesha, kungaxhomekeki ekubeni ingakanani ioksijini ekhoyo. Kwaye isiphumo sihle kakhulu: ukuchaneka yi-±(20PPM+5% yokufunda), kwaye ixesha lokuphendula lingaphantsi kwemizuzwana engama-20. Impendulo entle: ukusebenzisa umbala othile wokukhanya ukubala inani leemolekyuli zegesi ezingenambala ezinyibilikisiweyo emanzini.
1. Inzima ngendlela emangalisayo kwaye yenzelwe imisebenzi engcolileyo.
Nangona sisixhobo sokukhanya esikumgangatho ophezulu, i-RD-WDCO2 yenzelwe ihlabathi lokwenyani. Ikhankanya "ulwakhiwo lwayo olungaqhelekanga olungangeni manzi" olunokwahlulwa nokucocwa ngokulula. Ukugcinwa ngokuchanekileyo kubalulekile kwisixhobo esinokufakwa kwiitanki zefama yeentlanzi okanye ukujonga amanzi aphumayo.
Inikwe umlinganiselo we-IP68 ngokusemthethweni, oko kuthetha ukuba yeyona ikhuselekileyo eluthulini kwaye ingantywiliselwa emanzini ixesha elide. Kwaye bubungqina obungakumbi bokuba inamandla kangakanani kuba inokusebenza kuzo zonke iintlobo zobushushu obahlukeneyo, ukusuka kubanda njenge-minus 20 degrees ukuya kushushu njenge-plus 60 degrees Celsius, ngoko ke ingalunga nje kumlambo obandayo okanye itanki yemizi-mveliso efudumeleyo. Ifilosofi yoyilo ichazwe ngokugqibeleleyo ngumgca osuka kwincwadi yemiyalelo.
I-Shell ilula kwaye kulula ukuyifaka kwindawo.
Kwaye idibanisa inkqubo yangaphakathi ethambileyo nengaphandle eqinileyo elula ukuyisebenzisa ebantwini. Oku kuthetha ukuba bayazi ukuba kunokuba nzima kangakanani na phaya kwiindawo apho olu hlobo lolwazi lubaluleke kakhulu - njengeefama zeentlanzi okanye ukubukela indalo.
2. Ilinganisa okungaphezulu nje koko kusemanzini.
Eyona nto iphikisanayo nendayifumeneyo kukuba i-“Water Dissolved CO2 sensor” inokusebenza nayo nayiphi na into ngaphandle kwamanzi. Kuyabonakala ukuba incwadi yemiyalelo ibonisa ukuba inamandla okwenza izinto ezimbini, nto leyo eyenza ukuba ibe luncedo ngakumbi kunendlela ebizwa ngayo.
Ngokutsho komthombo, i-RD-WDCO2 ingasetyenziselwa ukulinganisa ubungakanani be-CO2 enyibilikisiweyo emanzini, kwaye ingasetyenziselwa nokujonga inqanaba le-CO2 kwiimeko ezishushu nezifumileyo.
Kwaye olu buchule buyenza ibe sisixhobo esiluncedo kuzo zonke iindawo ezahlukeneyo. Ingasetyenziswa njengoko bekucetyiwe kwi-"Aquaculture" kunye "nokuJonga uMgangatho waManzi", kodwa ikwalungele "ukuJonga iNdalo yeZindlu zokuHlaziya zezoLimo" kuba ukufuma okuphezulu kunokwenza kube nzima kwezinye iintlobo zeenzwa ze-CO2.
4. Inxibelelana ngolwimi lwedijithali oluntsonkothileyo
I-sensor ayisebenzi ukuba ayikwazi ukwabelana ngoko ikufumeneyo. I-RD-WDCO2 ayibonisi nje inani, ithetha neematshini ezahlukeneyo ngokusebenzisa iintlobo ezininzi zentetho yekhompyutha (iilwimi zedijithali) ukuze ikwazi ukuxelela ezinye izixhobo ukuba ingakanani i-CO2 ekhoyo. Ixhasa uluhlu olubanzi lweempawu zokukhupha kunye neenkqubo ezifana ne-RS485, i-UART, i-IIC.
Lo asingomyalezo oqhelekileyo. Ukuze ufumane ukufundwa ngeprotocol eqhelekileyo yeMODBUS nge-RS485, ikhompyutha kufuneka ithumele umtya othile womyalelo kwifomathi ye-hexadecimal. Umzekelo, ukuze ubuze isenzi #32 ngokufundwa kwayo kwe-CO2 yangoku, i-host ingathumela lo myalezo unekhowudi:
20 03 00 00 00 01 82 BB
Kwaye i-sensor iya kuphendula ngomyalezo wayo ongaqondakaliyo onolwazi olufunekayo:
20 03 02 01 AB 44 6C
Kule mpendulo, ulwazi oluphambili yi-01AB. Olu luxinzelelo lwe-CO2 kwimo ye-hex, olulingana ne-427ppm kwiidesimali. Ezi ngxoxo zithuleyo neziyimfihlo zezona zinto ziphambili phakathi kwehlabathi elisingqongileyo kunye neekhompyutha ezilijongayo, zitshintsha amanani alula ukusuka kwiisensa zibe lulwazi oluluncedo esinokulusebenzisa.
Isiphelo: Ubuchule Obufihliweyo KwiTekhnoloji Yemihla Ngemihla
Ukujonga nzulu incwadi yemiyalelo yobugcisa kubonisa ukuba nento ebonakala ngathi sisixhobo esincinci iyamangalisa kwiintlobo ezahlukeneyo zobunjineli. Inzwa enye ene-optics ephezulu yokubona igesi engabonakaliyo, uyilo oluqinileyo lokumelana neemeko ezinzima, kunye nemithetho yedijithali enzima yokwabelana ngento eyifumanayo. Sisikhumbuzo esinamandla sokuba ngasemva kwayo yonke idatha eqhuba ihlabathi lethu, kukho izisombululo zobugcisa ezintle neziqinileyo.
Kwaye oko kukwenza ucinge: zeziphi ezinye izixhobo ezingabonakaliyo ezibamba ngokungabonakaliyo, ezilawula iinkqubo esixhomekeke kuzo ngaphandle kokuba thina singazi?
Singabonelela ngezisombululo ezahlukeneyo
