Nkhani Zokhudza Kugwiritsa Ntchito Ma Sensor Amadzi Osungunuka Oxygen ku Southeast Asia Aquaculture

Kugwiritsa ntchito masensa amadzi osungunuka a oxygen (DO) ndi chitsanzo chofala komanso chopambana chaukadaulo wa IoT ku Southeast Asia aquaculture. Mpweya wosungunuka ndi chimodzi mwazinthu zofunika kwambiri zamadzimadzi, zomwe zimakhudza kwambiri kupulumuka, kuthamanga kwa kukula, ndi thanzi la mitundu yolimidwa.

Magawo otsatirawa amafotokoza momwe angagwiritsire ntchito pogwiritsa ntchito zochitika zosiyanasiyana komanso zochitika.

1. Kusanthula Kwachidziwitso Chodziwika: Famu Yaikulu Ya Shrimp ku Vietnam

Mbiri:
Vietnam ndi amodzi mwa omwe amagulitsa shrimp ku Southeast Asia. Famu yayikulu, yozama kwambiri ya vannamei shrimp ku Mekong Delta idakumana ndi ziwopsezo zambiri zakufa chifukwa chosasamalidwa bwino ndi okosijeni. Mwachizoloŵezi, ogwira ntchito ankayenera kuyeza magawo kangapo patsiku pokwera boti kupita ku dziwe lililonse, zomwe zinachititsa kuti deta isapitirire komanso kulephera kuyankha mwamsanga hypoxia yomwe imabwera chifukwa cha usiku kapena kusintha kwadzidzidzi.

Yankho:
Famuyo idakhazikitsa njira yowunikira madzi yanzeru ya IoT, yokhala ndi sensa ya okosijeni yosungunuka pa intaneti pachimake.

1. Kutumiza: Sensa imodzi kapena ziwiri za DO zidayikidwa mu dziwe lililonse, ndikuyikidwa pakuya pafupifupi 1-1.5 metres (malo oyambira amadzi a shrimp ntchito) pogwiritsa ntchito ma buoy kapena mitengo yokhazikika.
2. Kutumiza kwa Deta: Masensa amatumiza data yeniyeni ya DO ndi kutentha kwa madzi ku nsanja yamtambo kudzera pamaneti opanda zingwe (mwachitsanzo, LoRaWAN, 4G/5G).
3. Smart Control: Dongosololi linaphatikizidwa ndi ma aerators a dziwe. Malo otetezeka a DO adayikidwa (mwachitsanzo, malire otsika: 4 mg/L, malire apamwamba: 7 mg/L).
4. Zidziwitso ndi Kasamalidwe:
   • Kuwongolera Mwadzidzidzi: Pamene DO idatsikira pansi pa 4 mg / L, makinawo adayatsa ma aera; pamene idakwera pamwamba pa 7 mg / L, idazimitsa, kukwaniritsa mpweya wabwino ndikupulumutsa ndalama zamagetsi.
   • Ma alarm Akutali: Dongosololi lidatumiza zidziwitso kudzera pa SMS kapena zidziwitso za pulogalamu kwa woyang'anira famu ndi akatswiri ngati deta inali yachilendo (mwachitsanzo, kuchepa kosasintha kapena kutsika mwadzidzidzi).
   • Kusanthula kwa data: nsanja yamtambo idalemba mbiri yakale, kuthandiza kusanthula machitidwe a DO (mwachitsanzo, kumwa usiku, kusintha pambuyo pa kudyetsa) kuti akwaniritse bwino njira zodyetsera ndi kasamalidwe.

Zotsatira:

• Kuchepetsa Chiwopsezo: Pafupifupi kuthetsedwa kwa kufa kwa anthu ambiri ("kuyandama") komwe kumachitika chifukwa cha hypoxia mwadzidzidzi, kupititsa patsogolo kwambiri kuchuluka kwaulimi.
• Kupulumutsa Mtengo: Kuwongolera bwino kwa mpweya kunachepetsa nthawi yogwira ntchito yopanda pake, ndikupulumutsa pafupifupi 30% pamabilu amagetsi.
• Kuchita Bwino Kwambiri: Oyang'anira samafunikiranso kuyang'ana pamanja pafupipafupi ndipo amatha kuyang'anira maiwe onse kudzera pa mafoni awo a m'manja, kupititsa patsogolo kasamalidwe koyenera.
• Kukula Kokwanira: Malo okhazikika a DO amalimbikitsa kukula kwa shrimp, kupititsa patsogolo zokolola ndi kukula kwake.

2. Zochitika Zogwiritsa Ntchito Mayiko Ena Kumwera cha Kum'mawa kwa Asia

1. Thailand: Gulu la Gulu / Seabass Cage Culture
   • Chovuta: Chikhalidwe cha khola m'madzi otseguka chimakhudzidwa kwambiri ndi mafunde ndi mafunde, zomwe zimapangitsa kusintha kwamadzi mwachangu. Mitundu yochuluka kwambiri ngati grouper imakhudzidwa kwambiri ndi hypoxia.
   • Kugwiritsa ntchito: masensa a DO osagwirizana ndi Corrosion omwe amayikidwa m'makola amapereka kuyang'anira nthawi yeniyeni. Zidziwitso zimayambika ngati DO itsika chifukwa cha maluwa a algal kapena kusinthana kwamadzi kosakwanira, zomwe zimalola alimi kuyatsa ma aera apansi pamadzi kapena kusamutsa makola kuti apewe kuwonongeka kwakukulu kwachuma.
2. Indonesia: Maiwe a Integrated Polyculture
   • Chovuta: M'machitidwe a polyculture (mwachitsanzo, nsomba, shrimp, nkhanu), kuchuluka kwachilengedwe ndikwambiri, kugwiritsa ntchito okosijeni ndikofunikira, ndipo mitundu yosiyanasiyana imakhala ndi zofunikira zosiyanasiyana.
   • Kugwiritsa ntchito: Sensa imawunika mfundo zazikulu, kuthandiza alimi kumvetsetsa momwe chilengedwe chonse chimagwirira ntchito. Izi zimapangitsa kuti pakhale zisankho zambiri zasayansi pazakudya komanso nthawi zopatsa mpweya, kuonetsetsa kuti zamoyo zonse zizikhala bwino.
3. Malaysia: Mafamu Okongoletsa Nsomba
   • Chovuta: Nsomba zokongola zamtengo wapatali monga Arowana ndi Koi zimakhala ndi zofunika kwambiri pamadzi. Kuchepa kwa hypoxia kumatha kukhudza mtundu ndi mawonekedwe awo, kumachepetsa kwambiri mtengo wawo.
   • Kugwiritsa ntchito: masensa apamwamba kwambiri a DO amagwiritsidwa ntchito m'matangi ang'onoang'ono a konkriti kapena m'nyumba za Recirculating Aquaculture Systems (RAS). Izi zimaphatikizidwa ndi machitidwe a jekeseni wa okosijeni woyera kuti asunge DO pamlingo woyenera komanso wosasunthika, kuonetsetsa ubwino ndi thanzi la nsomba yokongoletsera.

3. Chidule cha Phindu Lachikulu Loperekedwa ndi Ntchito

4. Mavuto ndi Zochitika Zamtsogolo

Ngakhale kugwiritsa ntchito kufalikira, pali zovuta zina:

• Mtengo Woyamba Wogulitsa: Dongosolo lathunthu la IoT limayimirabe ndalama zambiri kwa alimi ang'onoang'ono, payekha.
• Kusamalira Sensor: Zomverera zimafuna kuyeretsedwa nthawi zonse (kuteteza biofouling) ndikuwongolera, kumafuna luso linalake laukadaulo kuchokera kwa ogwiritsa ntchito.
• Network Coverage: Zizindikiro zama netiweki zitha kukhala zosakhazikika m'malo ena akumidzi.

Future Trends:

1. Kutsika Mtengo wa Sensor ndi Kuchulukira Kwaukadaulo: Mitengo idzakhala yotsika mtengo kwambiri chifukwa cha kupita patsogolo kwaukadaulo komanso kuchuluka kwachuma.
2. Multi-Parameter Integrated Probes: Kuphatikiza masensa a DO, pH, kutentha, ammonia, salinity, etc., mu kafukufuku umodzi kuti apereke mbiri yabwino yamadzi.
3. AI ndi Big Data Analytics: Kuphatikiza luntha lochita kupanga osati kungochenjeza komanso kulosera zamtundu wamadzi ndikupereka upangiri wanzeru wowongolera (mwachitsanzo, kulosera kwa mpweya).
4. Chitsanzo cha "Sensors-as-a-Service": Kubwera kwa opereka chithandizo komwe alimi amalipira ndalama zothandizira m'malo mogula hardware, ndi wothandizira akugwira ntchito yosamalira ndi kusanthula deta.
5. Titha kuperekanso njira zosiyanasiyana zothetsera

   1. M'manja mita kwa Mipikisano parameter madzi khalidwe

   2. Dongosolo la Buoy loyandama lamtundu wamadzi wamitundu yambiri

   3. Burashi yotsuka yokha yamadzi ambiri amadzimadzi

   4. Seti yathunthu ya ma seva ndi pulogalamu yopanda zingwe, imathandizira RS485 GPRS / 4g/WIFI/LORA/LORAWAN

   Kuti mudziwe zambiri zamadzi zambiri,
