I lettuce eluhlaza iyachuma kwisisombululo sezondlo ngaphakathi kweitanki zokulima, zonke zilawulwa zizivamvo ezininzi ezisebenza ngokuzolileyo zomgangatho wamanzi.
Kwilabhoratri yeyunivesithi kwiPhondo laseJiangsu, ibhetshi yelettuce ikhula ngamandla ngaphandle komhlaba, ngenxa yenkqubo yokubeka iliso ye-hydroponic esekwe kwitekhnoloji ye-IoT encinci. Umphandi uZhang Jing wachaza ukuba inkqubo isebenzisa iinzwa ezininzi zomgangatho wamanzi ukujonga iiparamitha zesisombululo sezondlo ngexesha langempela, zidityaniswe neendlela zokulawula ezingaqondakaliyo ukulungelelanisa ngokuzenzekelayo umgangatho wamanzi ngokweemfuno zezityalo.
Njengoko itekhnoloji ye-hydroponic isanda kakhulu, ezi zinzwa zomgangatho wamanzi zingacacanga zidlala indima ebaluleke kakhulu. Ukusuka kumaziko ophando oluchwephesha ukuya kumakhaya aqhelekileyo, iinkqubo ezihlakaniphile ze-hydroponic ziguqula ngokuzolileyo iindlela zokulima zemveli.
01 Imeko yangoku yeHydroponic Technology
Xa kuthelekiswa nokulinywa komhlaba, i-hydroponics yenza ukuba isityalo sikhule ngokukhawuleza kwaye inciphisa iingxaki zezinambuzane. Kuba izityalo zisoloko zifunxa izondlo kwisisombululo sezondlo, kubalulekile ukujonga imilinganiselo yomgangatho wamanzi wesisombululo sezakhamzimba ze-hydroponic ngokukhawuleza nangokuchanekileyo, kwaye uzalise izondlo njengoko kufuneka.
Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-sensor kunye nokunciphisa iindleko, iinkqubo ze-smart hydroponic ziye zaqala ukusuka kumaziko ophando ukuya kumakhaya aqhelekileyo.
Inkqubo eqhelekileyo ye-smart hydroponic ihlala inamacandelo amathathu aphambili: abenzi boluvo, abalawuli, kunye nee-actuators.
Phakathi kwezi, iinzwa zinoxanduva lokuqokelela iiparitha ezahlukeneyo zomgangatho wamanzi, zisebenza "njengamehlo" kunye "neendlebe" zenkqubo. Ukuchaneka kunye nokuzinza kwabo kuchaza ngokuthe ngqo impumelelo okanye ukungaphumeleli kwayo yonke inkqubo ye-hydroponic.
02 Isishwankathelo esineNgcaciso yeeSensors ezingundoqo
Iinzwa ze-pH
Ixabiso le-pH libalulekile ekukhuleni kwesityalo kwi-hydroponics. Njengoko nabani na kwi-aquaculture esazi, olona luhlu lwe-pH lwemithombo yamanzi luphakathi kwe-7.5-8.5.
Izibonisi zomgangatho wamanzi we-pH zibhaqa ugxininiso lwe-ion ye-hydrogen kwizinto ezilinganisiweyo kwaye ziyiguqule ibe ziimpawu eziphumayo ezisebenzisekayo ezihambelanayo.
I-H + ion kwisisombululo isebenzisana ne-electrode ye-sensor ukuvelisa umqondiso we-voltage, kunye nobukhulu be-voltage bulinganiswe noxinaniso lwe-H +. Ngokulinganisa umqondiso we-voltage, ixabiso le-pH elihambelanayo lesisombululo lingafumaneka.
Iinzwa ezikhethekileyo ze-pH ezenzelwe usetyenziso lwe-hydroponic zifumaneka ngokurhweba, ezifana ne-autoponic pH sensors ezixhasa iiprothokholi zonxibelelwano eziqhelekileyo, ezinoluhlu lwemilinganiselo ye-0-14.00 pH kunye nesisombululo ukuya kwi-0.01 pH, eyenza ukubeka iliso kunye nokulawula ngokuchanekileyo.
IiSensors ze-Oxygen ezichithwe
Ioksijini enyibilikileyo yeyona nto iphambili ekukhuleni kweengcambu ezisempilweni kwizityalo ze-hydroponic. Imizimba yamanzi engangcoliswanga zizinto ezitya ioksijini igcina ioksijini enyibilikisiweyo kumanqanaba okugcwala.
Izinzwa zeoksijini ezinyibilikileyo zilinganisa ubungakanani beoksijini enyibilike emanzini.
Iimolekyuli ze-oksijini ezivela kwisisombululo esilinganisiweyo zihamba nge-membrane ekhethiweyo ye-sensor kwaye ihlanjululwe ngokuhambelanayo yokunciphisa okanye i-oxidation reactions kwi-cathode yangaphakathi kunye ne-anode, ngaxeshanye ivelisa izibonakaliso zangoku. Ubungakanani bangoku bulingana noxinaniso lweoksijini enyibilikileyo.
Izinzwa zeoksijini ezinyibilikileyo zifumaneka kwiindlela ezahlukeneyo: ezinye ziyakwazi ukumelana neemeko ezirhabaxa zendalo ngelixa zibonelela ngokuchaneka okugqwesileyo; abanye belungiselelwe ixesha lokuphendula, elilungele ukujongwa kwendawo kunye nezicelo zohlalutyo.
I-Ion Concentration Sensors
Izinzwa zoxinaniso lwe-ion zizixhobo ezibalulekileyo zokubeka iliso kwisisombululo sezondlo. Ukugxila kwee-ion ezithile ezifana ne-nitrate, i-ammonium, kunye ne-chloride kukuchaphazela ngokuthe ngqo ukukhula kwesityalo.
Umzekelo, izinzwa ze-ion ze-ammonium ezikhethekileyo zinokulinganisa umxholo we-ammonium emanzini endalo, emanzini angaphezulu, amanzi aphantsi komhlaba, kunye neenkqubo ezahlukeneyo zezolimo.
I-patent ye-hydroponic solution ion concentration ye-ion evela kwiyunivesiti yezolimo idibanisa i-ion electrode, i-sensor sensors, kunye ne-pH sensors, eyenza ukuqonda ngokukhawuleza kweenguqu ze-ion, ukuhluka kobushushu, kunye nokutshintsha kwe-pH kwizisombululo ze-hydroponic.
IiSensore ze-Electrical Conductivity (EC).
I-conductivity yombane luphawu oluphambili lokulinganisa i-ion concentration ye-ion kwisisombululo sezondlo, ebonisa ngokuthe ngqo inqanaba lokuchuma kwesisombululo sezondlo.
Iitransmitha ze-EC ezizenzekelayo eziyilelwe ngokukodwa unkcenkceshelo lwezolimo kunye neehydroponics zibonelela ngoluhlu lomlinganiselo ukuya ku-0-4000 µS/cm, ezixhasa iprothokholi zemveliso ezisemgangathweni, ezikwaziyo ukuqhagamshela kwiimpompo/iivalufa kunye nokulawula impompo/iitshitshi zevalvu.
Ubushushu kunye neziBonelelo zeTurbidity
Ubushushu buchaphazela ukukhula kweengcambu zesityalo kunye nomsebenzi we-metabolic, ngelixa i-turbidity ibonisa inani lamasuntswana amisiweyo kwisisombululo sezondlo.
Kwiiprojekthi zetanki ze-greenhouse hydroponic ezihlakaniphile, abaphuhlisi banokusebenzisa ubushushu bedijithali obuchanekileyo kunye neemodyuli zesivamvo zokufuma, ngokuchaneka kobushushu obuqhelekileyo obuyi-±0.3℃ kunye nesisombululo se-0.01℃.
Iinzwa ezikhethekileyo ze-turbidity zingasetyenziswa kunye nezixhobo ezininzi zeeparamitha ukujonga inqanaba le-turbidity yezisombululo zezondlo.
03 Izicelo eziDityanisiweyo kwiiSmart Systems
Idatha evela kuluvo lomntu ihlala ingonelanga ukubonisa ngokupheleleyo imeko-bume egcweleyo ye-hydroponic, isenza udibaniso lweenzwa ezininzi lube ngumkhwa okhulayo kwiinkqubo ze-smart hydroponic.
Iiprobes ezininzi zeparameter ezineendleko ezingabizi kakhulu zinokudibaniswa lula kunye neenkqubo zokulawula kunye neenkqubo ze-telemetry, ezifanelekileyo ukuthunyelwa kwexesha elide.
Amaqela ophando aphuhlise i-IoT-based based monitoring systems for hydroponics ezisebenzisa i-interfaces yesicelo esiphathwayo ukujonga ixesha lokwenyani kwiiparamitha ze-hydroponic zendalo, ezidityaniswe neendlela zokulawula ezihlakaniphile ukulungelelanisa imilinganiselo yesisombululo sesondlo samanzi ngokusekelwe kumava okusebenza kunye neemfuno zezityalo.
Iziphumo zovavanyo zibonisa ukuba xa ezo nkqubo zilawula izisombululo zezondlo, iiparitha eziphambili ezifana ne-pH kunye ne-conductivity yombane zinokugcina amaxabiso okusetwa kwangaphambili okuzinzileyo ngaphakathi kwamaxesha afanelekileyo.
04 Imingeni yobuChwephesha kunye neeNdlela zexesha elizayo
Nangona itekhnoloji ye-hydroponic sensor yenze inkqubela phambili ebonakalayo, imingeni emininzi isekhona. Uzinzo lwexesha elide, amandla okuchasa ukuchasana, kunye nokuphindaphindwa kwe-calibration ye-sensor yimiba ephambili kwizicelo ezisebenzayo.
Ngokukodwa ii-electrode ezikhethiweyo ze-ion ziyakwazi ukuphazamiseka kwezinye ii-ion kwaye zifuna ukulinganisa rhoqo.
Izinzwa ze-hydroponic zexesha elizayo ziya kuphuhlisa ekusebenzeni okuninzi, ubukrelekrele, kunye nokunciphisa iindleko.
Iisistim zoluvo oluphezulu sele zenza umlinganiselo wokusebenza okuphezulu kweeparamitha ezahlukeneyo, kubandakanya iklorofili, iipigments, i-fluorescence, i-turbidity, kunye nokunye.
Okwangoku, ngophuhliso lweeprojekthi zemithombo evulekileyo, imiqobo yokungena kwiinkqubo ze-smart hydroponic ziyancipha, okwenza abantu abaninzi bathathe inxaxheba kolu tshintsho lwezolimo.
Namhlanje, abahlali abaninzi basezidolophini baqala ukuzama ii-hydroponics zasekhaya. Kwiibhalkhoni zokuhlala kwizixeko ezahlukahlukeneyo, amagqabi aluhlaza akhula ngamandla kwiitanki ze-smart hydroponic ezisekwe kumaqonga e-microcontroller aziwayo.
Omnye umthandi wathi: “Izivamvo zomgangatho wamanzi ngundoqo wenkqubo yehydroponic—zifana ‘nencasa yezityalo’ zezityalo, ezisixelela ukuba zeziphi izondlo ezifuna ukulungiswa,” watsho njalo umthandi.
Ukuphumelela okuqhubekayo kwitekhnoloji ye-sensor kuguqula ukuchaneka kwezolimo ukusuka kwindawo efanelekileyo ukuya kwinyani.
