Lettuce e tala e mela hantle ka har'a tharollo ea limatlafatsi ka har'a litanka tsa temo, kaofela li laoloa ke li-sensor tse 'maloa tsa boleng ba metsi tse sebetsang ka khutso.
Laboratoring ea univesithi Profinseng ea Jiangsu, sehlopha sa lettuce se hola ka matla ntle le mobu, ka lebaka la sistimi ea tlhokomelo e bohlale ea hydroponic e thehiloeng theknolojing ea IoT ea sehlopha se senyenyane. Mofuputsi Zhang Jing o hlalositse hore sistimi e sebelisa li-sensor tse ngata tsa boleng ba metsi ho lekola liparamente tsa tharollo ea limatlafatsi ka nako ea sebele, hammoho le mekhoa ea taolo e sa hlakang ho fetola boleng ba metsi ka bohona ho latela litlhoko tsa lijalo.
Ha theknoloji ea hydroponic e ntse e ata haholo, li-sensor tsena tse sa bonahaleng tsa boleng ba metsi li bapala karolo ea bohlokoa haholo. Ho tloha litsing tsa lipatlisiso tsa litsebi ho ea malapeng a tloaelehileng, litsamaiso tse bohlale tsa hydroponic li fetola mekhoa ea temo ea setso ka lenyele.
01 Boemo ba Hona Joale ba Theknoloji ea Hydroponic
Ha ho bapisoa le temo ea mobu ea setso, hydroponics e nolofalletsa kholo ea lijalo ka potlako le ho fokotsa mathata a likokoanyana. Kaha lijalo li monya limatlafatsi khafetsa ho tsoa tharollong ea limatlafatsi, ho bohlokoa ho beha leihlo litekanyetso tsa boleng ba metsi a tharollo ea limatlafatsi tsa hydroponic kapele le ka nepo, le ho tlatsa limatlafatsi ha ho hlokahala.
Lilemong tsa morao tjena, ka nts'etsopele ea theknoloji ea sensor le phokotso ea litšenyehelo, litsamaiso tse bohlale tsa hydroponic li qalile ho tloha litsing tsa lipatlisiso ho ea malapeng a tloaelehileng.
Sistimi e tloaelehileng ea hydroponic e bohlale hangata e na le likarolo tse tharo tse kholo: li-sensor, balaoli le li-actuator.
Har'a tsena, li-sensor li ikarabella bakeng sa ho bokella liparamente tse fapaneng tsa boleng ba metsi, tse sebetsang e le "mahlo" le "litsebe" tsa sistimi. Ho nepahala ha tsona le botsitso ba tsona li khetholla ka ho toba katleho kapa ho hloleha ha sistimi eohle ea hydroponic.
02 Kakaretso e qaqileng ea Li-Sensor tsa Core
Li-sensor tsa pH
Boleng ba pH bo bohlokoa bakeng sa kholo ea lijalo ho hydroponics. Joalokaha mang kapa mang ea temong ea litlhapi a tseba, tekanyo e ntle ea pH bakeng sa mehloli ea metsi e pakeng tsa 7.5-8.5.
Li-sensor tsa boleng ba metsi tsa pH li lemoha mahloriso a li-ion tsa haedrojene linthong tse lekantsoeng ebe li li fetola matšoao a lumellanang a tlhahiso.
Li-ion tsa H+ tse ka har'a tharollo li sebelisana le elektrode ea sensor ho hlahisa lets'oao la motlakase, 'me boholo ba motlakase bo lekana le mahloriso a H+. Ka ho lekanya lets'oao la motlakase, boleng ba pH bo tsamaellanang ba tharollo bo ka fumanoa.
Li-sensor tse ikhethileng tsa pH tse etselitsoeng lits'ebetso tsa hydroponic li fumaneha khoebong, joalo ka li-sensor tsa pH tsa hydroponic tse iketsang tse tšehetsang liprothokholi tse tloaelehileng tsa puisano, tse nang le mefuta ea litekanyo ea 0-14.00 pH le qeto e fihlang ho 0.01 pH, e nolofalletsang tlhokomelo le taolo e nepahetseng.
Li-sensor tsa oksijene tse qhibilihisitsoeng
Oksijene e qhibilihisitsoeng ke ntlha ea bohlokoa bakeng sa kholo e phetseng hantle ea metso lijalong tsa hydroponic. Metsi a sa silafatsoang ke lintho tse jang oksijene a boloka oksijene e qhibilihisitsoeng maemong a ho tlala.
Li-sensor tsa oksijene tse qhibilihisitsoeng li lekanya bongata ba oksijene e qhibilihisitsoeng ka metsing.
Limolek'hule tsa oksijene tse tsoang tharollong e lekantsoeng li kenella ka har'a lera le khethiloeng la sensor 'me li feta liketsong tse lumellanang tsa phokotso kapa oxidation ho cathode le anode ea kahare, ka nako e le' ngoe li hlahisa matšoao a hona joale. Boholo ba hona joale bo lekana le mahloriso a oksijene a qhibilihileng.
Li-sensor tsa oksijene tse qhibilihisitsoeng tsa litsebi li fumaneha ka meralo e fapaneng: tse ling li khona ho mamella maemo a thata a tikoloho ha ka nako e ts'oanang li fana ka ho nepahala ho hoholo; tse ling li ntlafalitsoe bakeng sa nako ea karabelo, li loketse tlhahlobo ea libaka le lits'ebetso tsa tlhahlobo.
Li-sensor tsa Mahloriso a Ion
Li-sensor tsa mahloriso a ione ke lisebelisoa tsa bohlokoa bakeng sa ho lekola motsoako oa tharollo ea limatlafatsi. Mahloriso a li-ion tse itseng tse kang nitrate, ammonium le chloride a ama kholo ea lijalo ka kotloloho.
Mohlala, di-sensor tse ikgethang tsa ammonium ion di ka lekanya bongata ba ammonium metsing a tlhaho, metsing a ka hodima lefatshe, metsing a ka tlasa lefatshe, le ditshebedisong tse fapaneng tsa temo.
Patent bakeng sa sensor ea mahloriso a ion ea tharollo ea hydroponic ho tsoa univesithing ea temo e kopanya li-electrode tsa ion, li-sensor tsa mocheso, le li-sensor tsa pH, e leng se nolofalletsang kutloisiso e potlakileng ea liphetoho tsa mahloriso a ion, liphetoho tsa mocheso, le liphetoho tsa pH litharollong tsa hydroponic.
Li-sensor tsa Motlakase oa Motlakase (EC)
Ho tsamaisa motlakase ke sesupo sa bohlokoa se lekanyang mahloriso a li-ion kaofela tharollong ea limatlafatsi, se bonts'ang ka ho toba boemo ba monono ba tharollo ea limatlafatsi.
Li-transmitter tsa EC tse iketsang tse etselitsoeng ho nosetsa temo le hydroponics li fana ka litekanyo tse fihlang ho 0-4000 µS/cm, tse tšehetsang liprothokholi tse tloaelehileng tsa tlhahiso, tse khonang ho hokela lipompong/li-valve tsa tekanyo le ho laola li-switch tsa pompo/li-valve.
Li-sensor tsa Mocheso le Phefo
Mocheso o ama kgolo ya metso ya dijalo le tshebetso ya metabolism, ha mongobo o bontsha bongata ba dikarolwana tse leketlileng ka hara tharollo ya dimatlafatsi.
Mererong e bohlale ea tanka ea hydroponic ea greenhouse, bahlahisi ba ka sebelisa li-module tsa sensor tsa mocheso oa dijithale tse nepahetseng haholo le mongobo, ka ho nepahala ho tloaelehileng ha mocheso oa ±0.3℃ le qeto ea 0.01℃.
Li-sensor tse khethehileng tsa ho koaheloa ke metsi li ka sebelisoa ka lisebelisoa tsa li-parameter tse ngata ho beha leihlo boemo ba ho koaheloa ke metsi litharollong tsa limatlafatsi.
03 Likopo tse Kopantsoeng ho Smart Systems
Lintlha tse tsoang ho li-sensor ka bomong hangata ha lia lekana ho bonts'a tikoloho e felletseng ea hydroponic ka botlalo, e leng se etsang hore ho kopana ha li-sensor tse ngata e be mokhoa o ntseng o hola litsamaisong tse bohlale tsa hydroponic.
Li-probe tsa li-parameter tse ngata tse nang le meralo e theko e tlaase li ka kopanngoa habonolo le litsamaiso tsa taolo le litsamaiso tsa telemetry, tse loketseng ho sebelisoa nako e telele.
Lihlopha tsa lipatlisiso li thehile litsamaiso tse bohlale tsa ho beha leihlo tse thehiloeng ho IoT bakeng sa hydroponics tse sebelisang li-interface tsa lisebelisoa tsa mehala bakeng sa ho beha leihlo ka nako ea sebele ea liparamente tsa tikoloho ea hydroponic, hammoho le mekhoa e bohlale ea taolo ho fetola liparamente tsa boleng ba metsi a tharollo ea limatlafatsi ho latela boiphihlelo ba ts'ebetso le litlhoko tsa lijalo.
Liphetho tsa liteko li bontša hore ha litsamaiso tse joalo li laola litharollo tsa limatlafatsi, liparamente tsa bohlokoa tse kang pH le conductivity ea motlakase li ka boloka boleng bo tsitsitseng bo behiloeng esale pele ka nako e loketseng.
04 Liphephetso tsa Tekheniki le Mekhoa ea Nakong e Tlang
Leha theknoloji ea sensor ea hydroponic e entse tsoelo-pele e kholo, ho ntse ho e-na le liphephetso tse 'maloa. Botsitso ba nako e telele, bokhoni ba ho thibela litšila, le makhetlo a ho lekanya li-sensor ke mathata a maholo lits'ebetsong tse sebetsang.
Haholo-holo li-electrode tse khethang li-ion li kotsing ea ho sitisoa ke li-ion tse ling 'me li hloka ho lekanngoa khafetsa.
Li-sensor tsa hydroponic tsa nakong e tlang li tla nts'etsapele ho lebisa mesebetsing e mengata, bohlaleng le phokotsong ea litšenyehelo.
Mekhoa e tsoetseng pele ea ho lemoha e se e ntse e nolofalletsa ho lekanya ka mokhoa o phahameng liparamente tse fapaneng, ho kenyeletsoa chlorophyll, mebala, khanya, turbidity, le tse ling.
Ho sa le jwalo, ka ntshetsopele ya diporojeke tsa mohlodi o bulehileng, dithibelo tsa ho kena ha ditsamaiso tse bohlale tsa hydroponic di ntse di fokotseha, e leng se nolofalletsang batho ba bangata ho nka karolo phetohong ena ya temo.
Kajeno, baahi ba bangata ba litoropong ba qala ho leka ho sebelisa hydroponics lapeng. Mathuleng a bolulo metseng e fapaneng, meroho e tala e mela ka matla litankeng tse bohlale tsa hydroponic tse thehiloeng lipolatefomong tse tsebahalang tsa microcontroller.
“Lisensara tsa boleng ba metsi ke motheo oa litsamaiso tsa hydroponic—li tšoana le ‘li-tastebud’ tsa limela, li re bolella hore na ke limatlafatsi life tse hlokang ho lokisoa,” ho hlalositse motho ea chesehang.
Katleho e tswelang pele theknolojing ya disensor e fetola temo e nepahetseng ho tloha ho se setle ho ya nneteng.
