Case Studies ntawm Daim Ntawv Thov Dej Zoo Tshaj Tawm Oxygen Sensors nyob rau sab hnub tuaj Asia Aquaculture

Kev siv cov dej zoo yaj oxygen (DO) sensors yog ib qho piv txwv dav thiab ua tau zoo ntawm IoT thev naus laus zis hauv cov dej hiav txwv sab hnub tuaj Asia. Dissolved oxygen yog ib qho tseem ceeb tshaj plaws ntawm cov dej tsis zoo, cuam tshuam ncaj qha rau kev ciaj sia, kev loj hlob sai, thiab kev noj qab haus huv ntawm hom qoob loo.

Cov ntu hauv qab no qhia txog lawv daim ntawv thov los ntawm ntau yam kev tshawb fawb thiab cov xwm txheej.

1. Kev soj ntsuam cov xwm txheej: Ib qho chaw ua liaj ua teb loj hauv Nyab Laj

Keeb kwm:
Nyab Laj yog ib lub chaw xa khoom loj tshaj plaws nyob rau sab hnub tuaj Asia. Ib qho chaw loj, hnyav vannamei cw ua liaj ua teb hauv Mekong Delta tau ntsib cov neeg tuag coob vim yog kev tswj xyuas cov pa oxygen tsis zoo. Raws li kev lig kev cai, cov neeg ua haujlwm yuav tsum ntsuas cov ntsuas ntsuas ntau zaus hauv ib hnub los ntawm kev caij nkoj mus rau txhua lub pas dej, ua rau cov ntaub ntawv tsis tu ncua thiab tsis muaj peev xwm teb tau sai rau hypoxia tshwm sim los ntawm hmo ntuj lossis huab cua hloov pauv sai.

Kev daws:
Kev ua liaj ua teb tau siv IoT-raws li kev soj ntsuam xyuas dej zoo, nrog rau online yaj oxygen sensor ntawm nws cov tub ntxhais.

1. Kev xa tawm: Ib lossis ob lub DO sensors tau nruab rau hauv txhua lub pas dej, muab tso rau hauv qhov tob ntawm 1-1.5 meters (thawj txheej dej rau cw) siv cov buoys lossis cov ncej ruaj khov.
2. Kev xa cov ntaub ntawv: Cov sensors xa cov ntaub ntawv DO thiab dej kub hauv lub sijhawm mus rau huab platform ntawm wireless networks (xws li LoRaWAN, 4G / 5G).
3. Smart Control: Lub kaw lus tau koom ua ke nrog lub pas dej aerators. Kev nyab xeeb pib rau DO tau teeb tsa (piv txwv li, qis dua: 4 mg / L, txwv siab: 7 mg / L).
4. Kev ceeb toom thiab kev tswj hwm:
   • Tsis siv neeg tswj: Thaum DO poob qis dua 4 mg / L, lub kaw lus cia li qhib lub tshuab aerators; Thaum nws nce siab dua 7 mg / L, nws muab lawv tawm, ua tiav qhov tseeb aeration thiab txuag nqi hluav taws xob.
   • Tej thaj chaw deb Alarms: Lub kaw lus xa ntawv ceeb toom los ntawm SMS lossis app ceeb toom rau tus thawj coj ua liaj ua teb thiab cov kws tshaj lij yog tias cov ntaub ntawv txawv txav (xws li kev poob qis lossis poob sai sai).
   • Kev Tshawb Fawb Cov Ntaub Ntawv: Cov huab platform tau sau cov ntaub ntawv keeb kwm, pab txheeb xyuas DO cov qauv (xws li kev noj hmo hmo ntuj, kev hloov pauv tom qab pub mis) txhawm rau txhim kho cov tswv yim pub mis thiab tswj cov txheej txheem.

Cov txiaj ntsig:

• Kev txo qis: Yuav luag tshem tawm cov xwm txheej tuag coob ("floating") tshwm sim los ntawm hypoxia tam sim ntawd, txhim kho kev ua liaj ua teb ua tau zoo.
• Kev txuag nqi: Precision aeration txo lub sijhawm ua haujlwm tsis ua haujlwm ntawm aerators, txuag kwv yees li 30% ntawm cov nqi hluav taws xob.
• Txhim Kho Kev Ua Haujlwm Zoo: Cov thawj coj tsis xav tau kev kuaj xyuas phau ntawv ntau zaus thiab tuaj yeem saib xyuas txhua lub pas dej ntawm lawv lub xov tooj smartphones, txhim kho kev tswj hwm kev ua tau zoo.
• Optimized Loj hlob: Ib puag ncig DO ruaj khov txhawb nqa cov cw loj hlob zoo, txhim kho cov txiaj ntsig kawg thiab qhov loj me.

2. Daim ntawv thov Scenario nyob rau lwm lub tebchaws Esxias sab hnub tuaj

1. Thaib teb: Grouper/Seabass Cage Culture
   • Kev Sib Tw: Cage kab lis kev cai hauv cov dej qhib tau cuam tshuam los ntawm cov dej ntws thiab nthwv dej, ua rau cov dej hloov pauv sai. High-density hom zoo li grouper yog rhiab heev rau hypoxia.
   • Daim ntawv thov: Corrosion-resistant DO sensors muab tso rau hauv lub tawb muab kev saib xyuas lub sijhawm. Cov lus ceeb toom tau tshwm sim yog tias DO poob vim algal blooms lossis pauv dej tsis zoo, tso cai rau cov neeg ua liaj ua teb qhib lub tshuab nqus dej hauv qab lossis hloov lub tawb kom tsis txhob muaj kev lag luam loj.
2. Indonesia: Integrated Polyculture Ponds
   • Kev sib tw: Hauv cov kab ke ntau hom kab ke (xws li ntses, cws, roob ris), cov khoom siv roj ntsha muaj siab, kev noj cov pa oxygen yog qhov tseem ceeb, thiab ntau hom muaj qhov sib txawv ntawm DO.
   • Daim ntawv thov: Sensors saib xyuas cov ntsiab lus tseem ceeb, pab cov neeg ua liaj ua teb nkag siab txog cov qauv siv oxygen ntawm tag nrho cov ecosystem. Qhov no ua rau ntau qhov kev txiav txim siab txog kev noj zaub mov thiab lub sijhawm aeration, ua kom muaj ib puag ncig zoo rau txhua hom.
3. Malaysia: Ornamental Fish Farms
   • Kev Sib Tw: Cov ntses uas muaj txiaj ntsig zoo xws li Arowana thiab Koi muaj cov dej nruj heev. Me ntsis hypoxia tuaj yeem cuam tshuam rau lawv cov xim thiab mob, txo qis lawv cov nqi.
   • Daim ntawv thov: High-precision DO sensors yog siv nyob rau hauv me me pob zeb tso tsheb hlau luam los yog sab hauv tsev Recirculating Aquaculture Systems (RAS). Cov no tau koom ua ke nrog cov pa ntshiab oxygen txhaj tshuaj kom tswj tau DO ntawm qhov kev pom zoo thiab ruaj khov, kom ntseeg tau qhov zoo thiab kev noj qab haus huv ntawm cov ntses ornamental.

4. Kev sib tw thiab yav tom ntej Trends

Txawm hais tias siv dav dav, qee qhov kev sib tw tseem nyob:

• Tus nqi nqis peev pib: Ib qho kev ua tiav IoT tseem sawv cev rau tus nqi tseem ceeb rau cov neeg ua liaj ua teb me me.
• Kev Kho Sensors: Sensors yuav tsum tau ua kom huv si tsis tu ncua (kom tiv thaiv biofouling) thiab calibration, xav tau ib theem ntawm kev txawj ntse los ntawm cov neeg siv.
• Network Coverage: Network signals tuaj yeem tsis ruaj khov hauv qee thaj chaw ua liaj ua teb nyob deb.

Yav tom ntej Trends:

1. Kev poob qis Sensor nqi thiab kev siv thev naus laus zis: Cov nqi yuav pheej yig dua vim kev siv thev naus laus zis thiab kev lag luam ntawm cov nplai.
2. Multi-Parameter Integrated Probes: Integrating sensors rau DO, pH, kub, ammonia, salinity, thiab lwm yam, rau hauv ib qho kev sojntsuam kom muab cov dej zoo profile.
3. AI thiab Cov Ntaub Ntawv Loj Loj: Kev sib koom ua ke kev txawj ntse tsis yog kev ceeb toom nkaus xwb tab sis kuj los twv seb cov dej zoo li cas thiab muab cov lus qhia txog kev tswj hwm ntse (xws li, kev kwv yees aeration).
4. "Sensors-as-a-Service" Qauv: Kev tshwm sim ntawm cov chaw muab kev pabcuam uas cov neeg ua liaj ua teb them tus nqi pabcuam es tsis txhob yuav khoom kho vajtse, nrog rau tus neeg muab kev pabcuam tuav tswj thiab tshuaj xyuas cov ntaub ntawv.
5. Peb kuj tuaj yeem muab ntau yam kev daws teeb meem rau

   1. Handheld meter rau ntau qhov ntsuas dej zoo

   2. Floating Buoy system rau ntau qhov ntsuas dej zoo

   3. Tsis siv neeg tu txhuam rau ntau qhov ntsuas dej ntsuas

   4. Ua tiav cov servers thiab software wireless module, txhawb RS485 GPRS / 4g / WIFI / LORA / LORAWAN
