Izvo zvinoenderana nemamiriro ezvinhu aya kuti ma sensors akanyungudika eokisijeni, ane mabhenefiti awo akasiyana ehunyanzvi, zvishoma nezvishoma akapinda munzvimbo yekuona yeindasitiri yezvekurima uye akatanga kugadziridza nzira yeindasitiri yekutarisira kunaka kwemvura.

Tekinoroji Kubudirira: Kushanda Misimboti uye Yakakosha Yakanakira yeOptical Sensors.

Iyo yakakosha tekinoroji ye optical yakanyungudika okisijeni sensors yakavakirwa paiyo fluorescence quenching musimboti, inovandudza kuyerwa nzira iyo yakanyatso shandura yechinyakare yakanyungudika kuongorora okisijeni. Kana mwenje webhuruu unoburitswa ne sensor inovhenekera chinhu chakakosha chefluorescent, zvinhu zvacho zvinonakidzwa uye zvinoburitsa mwenje mutsvuku. Mamorekuru eokisijeni ane kugona kwakasiyana-siyana kutakura simba (kuburitsa mhedzisiro), saka kusimba uye nguva yerambi dzvuku rakaburitswa zvinopindirana nekusangana kwemamorekuru eokisijeni mumvura. Nekunyatso kuyera mutsauko wechikamu pakati pechiedza dzvuku chinofadza uye mwenje wekutarisa uye uchichienzanisa nemukati wekugadzirisa maitiro, iyo sensor inogona kunyatso verenga yakanyungudika oksijeni concentration mumvura. Kuita kwemuviri uku hakubatanidze kuita kwemakemikari, kudzivirira zvakawanda zvinokanganisa zvechinyakare electrochemical nzira.

Kuenzaniswa neyechinyakare electrochemical sensors, optical yakanyungudika okisijeni sensors inoratidza yakakwana yehunyanzvi mabhenefiti. Yokutanga ndiyo hunhu hwavo husina-oxygen-consuting, zvinoreva kuti havana zvakakosha zvekumhanya kwemvura kuyerera kana kubvongodza, zvichiita kuti vakwanise kunharaunda dzekurima dzakasiyana-siyana-angave madziva akadzikama kana matangi anoyerera anogona kupa mhedzisiro yekuyera kwayo. Yechipiri ndiyo yakanakisa kuyerwa kwekuita kwavo: chizvarwa chekupedzisira chemagetsi ekuona anogona kuwana nguva dzekupindura isingasviki masekonzi makumi matatu uye nekururama kwe ± 0.1 mg / L, zvichiita kuti vatore shanduko dzisinganzwisisiki muokisijeni yakanyungudika. Pamusoro pezvo, masensa aya anowanzo ratidza dhizaini yakafararira yemagetsi (DC 10-30V) uye akashongedzerwa neRS485 yekutaurirana nzvimbo inotsigira iyo MODBUS RTU protocol, zvichiita kuti zvive nyore kubatanidza mumasisitimu akasiyana ekutarisa.

Kushanda kwenguva refu kwekuchengetedza-yemahara ndechimwe chezvinhu zvinonyanya kufarirwa zve optical dissolved oxygen sensors pakati pevarimi. Traditional electrochemical sensors inoda nguva dzose membrane uye electrolyte kutsiva, nepo optical sensors inobvisa zvachose izvi zvinodyiwa, nehupenyu hwesevhisi inopfuura gore rimwe, zvichideredza zvakanyanya mari yekugadzirisa zuva nezuva uye mutoro webasa. Mukuru wezvenyanzvi wenzvimbo huru yezvekurima yemvura muShandong akati: “Kubva patakachinja tichishandisa masensor eoxygen akanyungudika, vashandi vedu vakachengetedza maawa anenge 20 pamwedzi pakuchengetedza masensor, uye kugadzikana kwedata kwave nani.

Panyaya yekugadzira dhizaini, yemazuva ano optical yakanyungudika okisijeni sensors zvakare funga zvakazara maitiro akasarudzika enzvimbo dzemvura. Nzvimbo dzepamusoro-dziviriro-yepamusoro (inowanzosvika IP68) inodzivirira zvachose kupinda kwemvura, uye pasi inogadzirwa ne316 simbi isina tsvina, inopa kuramba kwenguva refu kumunyu uye alkali corrosion. Masensa anowanzo kuve akashongedzerwa neNPT3/4 yakaomeswa nzvimbo yekumisikidza nyore uye kugadzirisa, pamwe chete nepombi isina mvura yekuisa kugarisa zvinodiwa zvekutarisa pakadzika kwakasiyana. Aya madhizaini anovimbisa kuvimbika uye kusimba kwema sensors munzvimbo dzakaoma dzekurima.

Zvikurukuru, kuwedzera kwehungwaru mabasa kwakawedzera kuwedzera kushanda kwe optical dissolved oxygen sensors. Mazhinji mamodheru matsva anoratidza akavakirwa-mukati tembiricha transmitters ane otomatiki tembiricha muripo, zvinobudirira kuderedza kuyerwa kukanganisa kunokonzerwa nekushanduka kwekushisa kwemvura. Zvimwe zvigadzirwa zvepamusoro-soro zvinogonawo kuendesa data munguva chaiyo kuburikidza neBluetooth kana Wi-Fi kune nharembozha kana mapuratifomu emakore, zvichigonesa kutarisa kure uye nhoroondo data mibvunzo. Kana mazinga eokisijeni akanyungudika achipfuura mazinga akachengeteka, sisitimu yacho inotumira ziviso kuburikidza nenharembozha yekuzivisa, mameseji, kana izwi rinokurudzira. Iyi ine hungwaru yekutarisa network inobvumira varimi kuti vagare vaine ruzivo nezvemhando yemvura uye kutora matanho panguva, kunyangwe vasipo.

Uku kufambira mberi kwekufambira mberi mu optical yakanyungudika okisijeni sensor tekinoroji haingogadzirise marwadzo emaitiro echinyakare ekutarisa asiwo inopa yakavimbika data rutsigiro rwekunatswa manejimendi ezve aquaculture, kushanda sembiru dzakakosha dzetekinoroji mukusimudzira kusimukira kweindasitiri kune hungwaru uye nemazvo.

Maitiro Ekushandisa: Maitiro eOptical Sensors Anovandudza Kurima Kubudirira
