Optical Dissolved Oxygen (ODO) sensors, tseem hu ua fluorescence-based sensors, yog cov cuab yeej siv niaj hnub no uas sib txawv nrog cov txheej txheem membrane electrode (Clark cells). Lawv lub ntsiab tseem ceeb yog kev siv cov fluorescence quenching los ntsuas qhov concentration ntawm cov pa oxygen hauv dej.
Txoj Cai Ua Haujlwm:
Lub sensor lub taub yog npog nrog ib daim nyias nyias impregnated nrog ib tug fluorescent dye. Thaum cov xim no zoo siab los ntawm ib qho kev sib txawv ntawm lub teeb xiav, nws tawm lub teeb liab. Yog tias cov pa oxygen molecules nyob hauv dej, lawv sib tsoo nrog cov xim zoo nkauj molecules, ua rau txo qis ntawm cov fluorescence siv thiab lub neej luv dua fluorescence. Los ntawm kev ntsuas qhov kev hloov pauv hauv fluorescence lub neej lossis kev siv zog, cov pa oxygen concentration tuaj yeem raug xam kom raug.
Cov yam ntxwv tseem ceeb:
- Tsis muaj Oxygen Consumption, Tsis muaj Electrolyte:
- Qhov no yog qhov tseem ceeb tshaj qhov sib txawv ntawm cov txheej txheem membrane electrode. Optical sensors tsis haus cov pa oxygen los ntawm cov qauv, muab cov txiaj ntsig zoo dua, tshwj xeeb tshaj yog nyob rau hauv cov dej ntws qis lossis cov dej zoo li qub.
- Tsis tas yuav hloov cov electrolytes los yog daim nyias nyias, txo kev txij nkawm.
- Low Maintenance, Siab Stability:
- Tsis muaj teeb meem nrog daim nyias nyias clogging, electrode lom, los yog electrolyte paug.
- Lub sijhawm calibration ntev, feem ntau yuav tsum tau calibration tsuas yog txhua ob peb lub hlis lossis ntev dua.
- Teb ceev ceev thiab siab raug:
- Cov lus teb ceev heev rau cov kev hloov pauv hauv cov pa oxygen, ua rau lub sijhawm tiag tiag ntawm kev hloov pauv dej zoo.
- Kev ntsuas tsis cuam tshuam los ntawm kev khiav nrawm lossis cuam tshuam cov khoom xws li sulfides, muab qhov tseeb thiab ruaj khov piv rau cov txheej txheem ib txwm muaj.
- Minimal Long-Term Drift:
- Cov khoom ntawm fluorescent zas xim yog qhov ruaj khov heev, ua rau muaj teeb meem tsawg tsawg thiab ua kom muaj kev ntseeg siab rau kev ntsuas mus ntev.
- Yooj yim siv:
- Feem ntau ntsaws-thiab-ua si, tsis muaj sijhawm ntev polarization xav tau tom qab pib; npaj rau kev ntsuas tam sim.
Qhov tsis zoo:
- Tus nqi pib siab dua: Feem ntau kim dua li cov tshuaj membrane electrode sensors.
- Fluorescent Membrane muaj lub neej ntev: Txawm hais tias ntev (feem ntau yog 1-3 xyoos), daim nyias nyias yuav kawg photodegrade los yog fouled thiab yuav tsum tau hloov.
- Muaj Peev Xwm Fouling los ntawm Roj thiab Algae: Cov roj hnyav hnyav los yog biofouling ntawm lub sensor nto tuaj yeem cuam tshuam nrog lub teeb excitation thiab txais tos, yuav tsum tau ntxuav.
2. Daim ntawv thov Scenarios
Vim lawv cov yam ntxwv zoo heev, optical yaj oxygen sensors tau siv dav hauv ntau qhov chaw uas yuav tsum tau saib xyuas tas li thiab meej DO:
- Kev kho dej khib nyiab:
- Ib daim ntawv thov tseem ceeb. Siv los saib xyuas DO hauv aeration tso tsheb hlau luam thiab aerobic / anaerobic zones kom ua kom zoo dua aeration, ua kom muaj kev tswj xyuas meej rau kev txuag hluav taws xob thiab txhim kho kev kho mob.
- Natural Water Body Monitoring (Rivers, Lakes, Reservoirs):
- Siv nyob rau hauv cov chaw saib xyuas ib puag ncig los ntsuas lub cev dej lub peev xwm ua kom huv ntawm tus kheej, eutrophication xwm txheej, thiab muaj peev xwm hypoxia, muab cov ntaub ntawv rau kev tiv thaiv ecological.
- Aquaculture:
- DO yog lub neej ntawm aquaculture. Optical sensors pab 24/7 saib xyuas hauv pas dej thiab tso tsheb hlau luam. Lawv tuaj yeem ua rau lub tswb nrov thiab cia li qhib aerators thaum qib qis qis, tiv thaiv ntses tua thiab tiv thaiv ntau lawm.
- Kev Tshawb Fawb Txog Kev Tshawb Fawb:
- Siv hauv kev tshawb fawb dej hiav txwv, kev tshawb fawb limnological, thiab kev sim ecotoxicology qhov twg cov ntaub ntawv muaj tseeb, tsis tshua muaj kev cuam tshuam DO yog qhov tseem ceeb.
- Industrial txheej txheem dej:
- Nyob rau hauv cov tshuab xws li fais fab nroj tsuag thiab tshuaj nroj tsuag dej txias, xyuas DO los tswj corrosion thiab biofouling.
3. Daim ntawv thov Case Study hauv Philippines
Raws li lub teb chaws archipelagic, lub Philippines kev lag luam cia siab rau kev lag luam thoob dej yug ntses thiab kev ncig ua si, thaum tseem ntsib cov teeb meem dej paug los ntawm nroog loj. Yog li ntawd, kev saib xyuas dej zoo, tshwj xeeb tshaj yog rau cov pa oxygen yaj, yog qhov tseem ceeb heev.
Case Study: Smart DO Monitoring thiab Aeration System hauv Laguna de Bay Aquaculture Zones
Keeb kwm:
Laguna de Bay yog lub pas dej loj tshaj plaws hauv tebchaws Philippines, nrog rau thaj chaw ib puag ncig yog qhov tseem ceeb rau kev cog qoob loo, feem ntau rau Tilapia thiab Milkfish (Bangus). Txawm li cas los xij, lub pas dej ntsib kev hem thawj los ntawm eutrophication. Thaum lub caij ntuj sov kub, dej stratification tuaj yeem ua rau hypoxia hauv cov khaubncaws sab nraud povtseg, feem ntau ua rau cov ntses tua loj heev ("ntses tua"), ua rau muaj kev lag luam loj rau cov neeg ua liaj ua teb.
Kev daws teeb meem:
Lub Bureau of Fisheries thiab Aquatic Resources (BFAR), koom tes nrog tsoomfwv hauv nroog, txhawb nqa kev siv cov dej ntse saib xyuas thiab tswj kev ua haujlwm raws li cov khoom siv kho qhov muag yaj cov pa oxygen sensors hauv cov lag luam loj loj thiab thaj chaw tseem ceeb ntawm lub pas dej.
System Cheebtsam thiab Workflow:
- Kev Saib Xyuas Cov Nodes: Ntau qhov ntsuas dej zoo buoys nruab nrog kho qhov muag DO sensors tau muab tso rau ntawm ntau lub ntsiab lus hauv cov pas dej ntses (tshwj xeeb tshaj yog nyob rau hauv qhov tob) thiab qhov chaw tseem ceeb hauv lub pas dej. Cov sensors tau xaiv vim:
- Low Maintenance: Lawv txoj haujlwm tsis tu ncua ntev yog qhov zoo tagnrho rau thaj chaw uas muaj cov neeg ua haujlwm tsawg.
- Kev tiv thaiv kev cuam tshuam: Tsis tshua muaj kev ua tsis tiav los ntawm fouling nyob rau hauv organically nplua nuj thiab turbid aquaculture dej.
- Cov ntaub ntawv tiag tiag: Muaj peev xwm muab cov ntaub ntawv txhua feeb, tso cai rau kev tshawb pom sai sai ntawm DO tee.
- Cov ntaub ntawv xa mus: Cov ntaub ntawv sensor raug xa mus rau lub sijhawm tiag tiag ntawm cov tes hauj lwm wireless (xws li GPRS / 4G lossis LoRa) mus rau huab platform thiab cov neeg ua liaj ua teb mobile apps.
- Smart Control thiab Ceeb Toom Thaum Ntxov:
- Platform Sab: Lub platform huab tau teeb tsa nrog DO lub tswb pib (piv txwv li, qis dua 3 mg / L).
- Cov Neeg Siv Sab: Cov neeg ua liaj ua teb tau txais cov suab ceeb toom / pom pom, SMS, lossis ceeb toom app.
- Tsis Siv Neeg Tswj: Lub kaw lus tuaj yeem qhib lub tshuab aerator kom txog thaum DO qib rov qab mus rau qhov chaw nyab xeeb.
Cov txiaj ntsig:
- Txo cov ntses tuag: Cov lus ceeb toom ntxov thiab tsis siv neeg aeration tau ua tiav tiv thaiv ntau yam ntses tua cov xwm txheej tshwm sim los ntawm DO qib qis thaum hmo ntuj lossis sawv ntxov ntxov.
- Txhim kho kev ua liaj ua teb: Cov neeg ua liaj ua teb tuaj yeem tswj hwm kev pub mis thiab aeration ntau dua kev tshawb fawb, txo cov nqi hluav taws xob (los ntawm kev zam 24/7盲目 kev ua haujlwm ntawm aerators) thiab txhim kho kev hloov pauv hloov pauv thiab cov ntses loj hlob.
- Cov ntaub ntawv rau Kev Tswj Xyuas Ib Cheeb Tsam: Kev soj ntsuam cov chaw nres tsheb hauv lub pas dej muab BFAR nrog cov ntaub ntawv mus sij hawm ntev spatiotemporal DO, pab txheeb xyuas eutrophication tiam sis thiab tsim ntau txoj cai tswj xyuas pas dej.
Cov ntsiab lus:
Hauv cov tebchaws tsim kho xws li Philippines, qhov chaw aquaculture ntsib kev pheej hmoo siab thiab kev tsim kho vaj tse tuaj yeem sib tw, kho qhov muag yaj cov pa oxygen sensors tau ua pov thawj tias yog cov cuab yeej thev naus laus zis zoo tshaj plaws rau kev ua dej hauv dej thiab kev tswj xyuas ib puag ncig zoo vim lawv cov kav ntev, kev saib xyuas qis, thiab kev ntseeg siab. Lawv tsis tsuas yog pab cov neeg ua liaj ua teb txo cov kev pheej hmoo thiab nce nyiaj tau los tab sis tseem muab cov ntaub ntawv muaj zog txhawb nqa los tiv thaiv Philippines cov dej muaj txiaj ntsig ecosystems.
