Chidule
Chifukwa cha kukulirakulira kwa ulimi wa m'madzi komanso kufunika koteteza zachilengedwe m'madzi, njira zodziwika bwino zowunikira ubwino wa madzi sizingakwaniritsenso zofunikira zenizeni komanso zosiyanasiyana. Pepalali likuwunika mwadongosolo mfundo zaukadaulo ndi kufunika kogwiritsa ntchito masensa oyandama amitundu yosiyanasiyana m'njira za ulimi wa m'madzi oyera komanso m'malo am'madzi. Kudzera mu kuyesa koyerekeza, ubwino wa magwiridwe antchito powunikira magawo ofunikira monga mpweya wosungunuka, pH, turbidity, ndi conductivity zatsimikiziridwa. Kuphatikiza apo, kuphatikiza ukadaulo wa IoT pamakina owunikira anzeru kukukambidwa. Kafukufuku wamilandu akuwonetsa kuti ukadaulo uwu umachepetsa nthawi yoyankha zolakwika zamtundu wa madzi ndi 83% ndikuchepetsa kuchuluka kwa matenda a ulimi wa m'madzi ndi 42%, kupereka chithandizo chodalirika chaukadaulo cha ulimi wamakono wa m'madzi ndi chitetezo cha chilengedwe cha m'madzi.
1. Mfundo Zaukadaulo ndi Kapangidwe ka Machitidwe
Dongosolo loyandama la sensa ya multi-parameter limagwiritsa ntchito kapangidwe ka modular, ndi zigawo zazikulu kuphatikizapo:
- Sensor Array: Sensor yosakanikirana ya okosijeni yosakanikirana (± 0.1 mg/L molondola), electrode yagalasi ya pH (± 0.01), probe ya conductivity ya ma electrode anayi (± 1% FS), chipangizo chogawa mpweya (0–4000 NTU).
- Kapangidwe kake koyandama: Nyumba ya polyethylene yokhala ndi mphamvu ya dzuwa komanso zolimbitsa pansi pa madzi.
- Kutumiza deta: Kumathandizira kutumiza kwa 4G/BeiDou kwa mitundu iwiri ndi ma frequency osinthika a sampling (mphindi 5 mpaka maola 24).
- Dongosolo Lodziyeretsa Lokha: Chipangizo chotsukira cha ultrasonic choletsa kuwononga zinthu chimawonjezera nthawi yokonza mpaka masiku 180.
2. Kugwiritsa Ntchito mu Ngalande za Ulimi wa Madzi Abwino
2.1 Kulamulira kwa Mpweya Wosungunuka Modabwitsa
M'madera olima a Macrobrachium rosenbergii ku Jiangsu, netiweki ya sensor imatsata kusinthasintha kwa DO nthawi yeniyeni (2.3–8.7 mg/L). Pamene kuchuluka kwa mpweya kumatsika pansi pa 4 mg/L, ma aerator amayamba kugwira ntchito okha, zomwe zimachepetsa zochitika za hypoxia ndi 76%.
2.2 Kukonza Zakudya Zopatsa Thanzi
Mwa kulumikiza pH (6.8–8.2) ndi deta ya turbidity (15–120 NTU), chitsanzo chodyetsa champhamvu chinapangidwa, zomwe zinapangitsa kuti chakudya chigwiritsidwe ntchito bwino ndi 22%.
3. Kupita patsogolo mu Kuyang'anira Zachilengedwe za M'nyanja
3.1 Kusinthasintha kwa Mchere
Ma electrode a titanium alloy amasunga mayankho olunjika (R² = 0.998) pamitundu yonse ya mchere wa 5–35 psu, ndipo kusuntha kwa deta <3% kunawonedwa mu mayeso a Fujian a m'nyanja.
3.2 Kachitidwe Kobwezera Mafunde
Njira yoyambira yosinthira madzi imachotsa kusokonezeka kwa madzi chifukwa cha kusinthasintha kwa mafunde pa muyeso wa ammonia nayitrogeni (0–2 mg/L), zomwe zimachepetsa cholakwika kufika pa ± 5% mu mayeso a m'mphepete mwa nyanja ya Qiantang River.
4. Mayankho Ogwirizanitsa IoT
Ma node a Edge computing amathandiza kukonza deta ya m'deralo (kuchepetsa phokoso, kuchotsa zinthu zina), pomwe nsanja zamtambo zimathandizira kusanthula kwamitundu yambiri:
- Mapu otentha a malo otseguka a algae
- Mitundu ya LSTM ikuneneratu za kusintha kwa khalidwe la madzi kwa maola 72
- Zidziwitso za pulogalamu ya m'manja (kuchedwa kwa mayankho
5. Kusanthula Mtengo ndi Phindu
Poyerekeza ndi zitsanzo zachikhalidwe zamanja:
- Ndalama zowunikira zimachepetsedwa ndi 62% pachaka
- Kuchuluka kwa deta kwawonjezeka ndi 400-folds
- Machenjezo okhudza maluwa a algae adaperekedwa maola 48 m'mbuyomu
- Kuchuluka kwa moyo wa ulimi wa m'madzi kwakwera kufika pa 92.4%
6. Mavuto ndi Ziyembekezo Zamtsogolo
Zoletsa zomwe zilipo pano zikuphatikizapo kusokoneza kwa biofouling (makamaka pamwamba pa 28°C) ndi kusokoneza kwa cross-parameter. Malangizo amtsogolo akuphatikizapo:
- Zipangizo zoyezera zochokera ku graphene
- Kuwongolera loboti loyenda pansi pa madzi lokha
- Kutsimikizira deta pogwiritsa ntchito blockchain
Mapeto
Machitidwe owunikira zinthu zosiyanasiyana omwe akuyandama akuyimira kusintha kwaukadaulo kuchokera ku "kusankha zitsanzo nthawi ndi nthawi" kupita ku "kuzindikira kosalekeza," zomwe zimapereka chithandizo chofunikira kwambiri pa usodzi wanzeru komanso kusunga zachilengedwe zam'madzi. Mu 2023, Unduna wa Zaulimi ku China udaphatikiza zida zotere muMiyezo Yamakono ya Ulimi wa Nsomba, zomwe zikusonyeza kuti anthu ambiri adzalandira chithandizochi mtsogolo.
Tikhozanso kupereka njira zosiyanasiyana zothetsera mavutowa
1. Chida chogwiritsira ntchito m'manja cha ubwino wa madzi okhala ndi magawo ambiri
2. Dongosolo loyandama la Buoy la ubwino wa madzi okhala ndi magawo ambiri
3. Burashi yoyeretsera yokha ya sensa yamadzi yokhala ndi magawo ambiri
4. Seti yonse ya ma seva ndi mapulogalamu opanda zingwe, imathandizira RS485 GPRS /4g/WIFI/LORA/LORAWAN
Kuti mudziwe zambiri zokhudza sensa yamadzi zambiri,
