Ndi chifukwa cha izi kuti masensa owunikira mpweya wosungunuka, omwe ali ndi ubwino wawo wapadera, pang'onopang'ono alowa m'munda wa masomphenya a makampani opanga nsomba ndikuyamba kusintha njira yoyendetsera bwino madzi m'makampani opanga nsomba.
Kupita Patsogolo kwa Ukadaulo: Mfundo Zogwirira Ntchito ndi Ubwino Wofunika wa Masensa Owona
Ukadaulo waukulu wa masensa osungunuka a okosijeni umakhazikitsidwa pa mfundo yozimitsira kuwala, njira yatsopano yoyezera yomwe yasintha kwathunthu kuwunika kwachikhalidwe kwa okosijeni kosungunuka. Pamene kuwala kwabuluu kotulutsidwa ndi sensa kumawunikira zinthu zapadera za kuwala, zinthuzo zimayatsidwa ndipo zimatulutsa kuwala kofiira. Mamolekyu a okosijeni ali ndi mphamvu yapadera yonyamula mphamvu (kupanga mphamvu yozimitsira), kotero mphamvu ndi nthawi ya kuwala kofiira kotulutsidwa zimakhala zofanana ndi kuchuluka kwa mamolekyu a okosijeni m'madzi. Poyesa molondola kusiyana kwa gawo pakati pa kuwala kofiira kolimbikitsidwa ndi kuwala kofotokozera ndikuyerekeza ndi ma values owerengera mkati, sensa imatha kuwerengera molondola kuchuluka kwa okosijeni kosungunuka m'madzi. Njirayi yakuthupi siyikuphatikiza machitidwe a mankhwala, kupewa zovuta zambiri za njira zachikhalidwe zamagetsi.
Poyerekeza ndi masensa achikhalidwe amagetsi, masensa opangidwa ndi mpweya wosungunuka amawonetsa ubwino waukadaulo wonse. Choyamba ndi khalidwe lawo losagwiritsa ntchito mpweya, zomwe zikutanthauza kuti alibe zofunikira zapadera pa liwiro la kuyenda kwa madzi kapena kugwedezeka, zomwe zimapangitsa kuti zikhale zoyenera malo osiyanasiyana olimapo—kaya maiwe osakhazikika kapena matanki oyenda angapereke zotsatira zolondola zoyezera. Chachiwiri ndi momwe amayezera bwino kwambiri: mbadwo waposachedwa wa masensa opangidwa ndi kuwala umatha kupeza nthawi yoyankha yosakwana masekondi 30 komanso kulondola kwa ±0.1 mg/L, zomwe zimawathandiza kuti azitha kujambula kusintha pang'ono kwa mpweya wosungunuka. Kuphatikiza apo, masensawa nthawi zambiri amakhala ndi kapangidwe ka magetsi ambiri (DC 10-30V) ndipo ali ndi ma interface olumikizirana a RS485 omwe amathandizira protocol ya MODBUS RTU, zomwe zimapangitsa kuti zikhale zosavuta kuziphatikiza mu machitidwe osiyanasiyana owunikira.
Kugwira ntchito kosasamalira kwa nthawi yayitali ndi chimodzi mwa zinthu zodziwika bwino za masensa osungunuka a okosijeni pakati pa alimi. Masensa achikhalidwe amagetsi amafuna kusintha nembanemba ndi ma electrolyte nthawi zonse, pomwe masensa owunikira amachotsa kwathunthu zinthu zogwiritsidwa ntchito izi, zomwe zimatha kugwira ntchito kwa nthawi yoposa chaka chimodzi, zomwe zimachepetsa kwambiri ndalama zosamalira tsiku ndi tsiku komanso ntchito. Mtsogoleri waukadaulo wa malo akuluakulu osungiramo nsomba ku Shandong adati: "Kuyambira pomwe titasinthira ku masensa osungunuka a okosijeni, ogwira ntchito athu okonza asunga maola pafupifupi 20 pamwezi pa ntchito yosamalira masensa, ndipo kukhazikika kwa deta kwasintha kwambiri. Sitiyeneranso kuda nkhawa ndi ma alarm abodza omwe amabwera chifukwa cha kusuntha kwa masensa."
Ponena za kapangidwe ka zida, masensa amakono a okosijeni osungunuka amaganiziranso mokwanira makhalidwe apadera a malo okhala nsomba. Makoma otetezedwa kwambiri (nthawi zambiri amafika pa IP68) amaletsa madzi kulowa, ndipo pansi pake amapangidwa ndi chitsulo chosapanga dzimbiri cha 316, chomwe chimapereka kukana kwa nthawi yayitali ku mchere ndi dzimbiri la alkali. Masensa nthawi zambiri amakhala ndi ma interface a NPT3/4 kuti azitha kuyika mosavuta komanso kukhazikika, komanso mapaipi osalowa madzi kuti akwaniritse zosowa zowunikira pamlingo wosiyanasiyana. Tsatanetsatane wa kapangidwe kameneka umatsimikizira kudalirika ndi kulimba kwa masensa m'malo ovuta a ulimi.
Chochititsa chidwi n'chakuti, kuwonjezera ntchito zanzeru kwawonjezera kwambiri magwiridwe antchito a masensa osungunuka a okosijeni. Mitundu yambiri yatsopano ili ndi ma transmitter omangidwa mkati omwe ali ndi chiwongolero cha kutentha chokha, zomwe zimachepetsa bwino zolakwika zoyezera zomwe zimachitika chifukwa cha kusinthasintha kwa kutentha kwa madzi. Zinthu zina zapamwamba zimatha kutumizanso deta nthawi yeniyeni kudzera pa Bluetooth kapena Wi-Fi ku mapulogalamu am'manja kapena nsanja zamtambo, zomwe zimathandiza kuyang'anira kutali ndi mafunso a data yakale. Pamene kuchuluka kwa okosijeni kosungunuka kumaposa malire otetezeka, dongosololi limatumiza machenjezo nthawi yomweyo kudzera pazidziwitso zam'manja, mauthenga a pafoni, kapena mawu ofunikira. Netiweki yowunikira yanzeruyi imalola alimi kudziwa za momwe madzi alili komanso kuchitapo kanthu panthawi yake, ngakhale atakhala kunja kwa malo.
Kupita patsogolo kumeneku mu ukadaulo wa optical distilled oxygen sensor sikuti kumangothetsa mavuto a njira zowunikira zachikhalidwe komanso kumapereka chithandizo chodalirika cha deta pakuwongolera bwino ulimi wa nsomba, zomwe zimagwira ntchito ngati mizati yofunika kwambiri yaukadaulo pakulimbikitsa chitukuko cha makampaniwa kuti chikhale chanzeru komanso cholondola.
Zotsatira za Ntchito: Momwe Masensa Owona Amathandizira Kugwira Ntchito Mwachangu pa Ulimi
Masensa oyezera mpweya wosungunuka apeza zotsatira zabwino kwambiri pakugwiritsa ntchito bwino ulimi wa m'madzi, ndipo phindu lawo latsimikizika m'mbali zosiyanasiyana, kuyambira kupewa kufa kwa anthu ambiri mpaka kukulitsa zokolola ndi ubwino. Chitsanzo chodziwika bwino ndi Baitan Lake Aquaculture Base ku Huangzhou District, Huanggang City, Hubei Province, komwe ma monitor asanu ndi atatu a madigiri 360-degree onse nyengo ndi masensa oyezera mpweya wosungunuka adayikidwa, omwe adaphimba maekala 2,000 a madzi m'madziwe 56 a nsomba. Cao Jian, katswiri wa zaukadaulo, anafotokoza kuti: "Kudzera mu deta yowunikira nthawi yeniyeni pazida zamagetsi, titha kuzindikira nthawi yomweyo zolakwika. Mwachitsanzo, pamene mulingo wa mpweya wosungunuka pa Monitoring Point 1 ukuwonetsa 1.07 mg/L, ngakhale kuti zomwe zachitika zingasonyeze kuti ndi vuto lofufuza, timadziwitsa alimi nthawi yomweyo kuti ayang'ane, ndikuwonetsetsa kuti ali otetezeka kwathunthu." Njira yowunikira nthawi yeniyeniyi yathandiza maziko kupewa ngozi zambiri zobwerera m'madzi zomwe zimachitika chifukwa cha hypoxia. Msodzi wakale Liu Yuming anati: “Kale, tinkada nkhawa ndi kuchepa kwa mpweya m’thupi nthawi iliyonse mvula ikagwa ndipo sitinkagona bwino usiku. Tsopano, ndi ‘maso amagetsi’ amenewa, akatswiri amatidziwitsa za deta iliyonse yolakwika, zomwe zimatithandiza kusamala msanga.”
Mu zochitika zaulimi zomwe zimakhala ndi anthu ambiri, masensa osungunuka a okosijeni ndi omwe amachita gawo lofunika kwambiri. Kafukufuku wochokera ku malo osungira nsomba za digito a "Future Farm" ku Huzhou, Zhejiang, akuwonetsa kuti mu thanki ya mamita 28 yokhala ndi pafupifupi 3,000 jin ya nsomba za ku California (pafupifupi 6,000 nsomba)—yofanana ndi kuchuluka kwa ekala imodzi m'madziwe achikhalidwe—kasamalidwe ka okosijeni wosungunuka kamakhala vuto lalikulu. Kudzera mu kuyang'anira nthawi yeniyeni ndi masensa opangidwa ndi maso ndi makina olumikizirana anzeru, malo osungira nsomba adachepetsa bwino kufa kwa nsomba kuchokera pa 5% m'mbuyomu kufika pa 0.1%, pomwe adapeza kuwonjezeka kwa 10%-20% pa mu. Katswiri waulimi Chen Yunxiang adati: "Popanda deta yeniyeni ya okosijeni wosungunuka, sitingayese kuyesa kuchuluka kwa nsomba."
Makina Oyendetseranso Zamoyo Zam'madzi (RAS) ndi gawo lina lofunika kwambiri pomwe masensa osungunuka a okosijeni amawonetsa kufunika kwawo. "Blue Seed Industry Silicon Valley" ku Laizhou Bay, Shandong, yamanga malo ochitira masewera olimbitsa thupi a RAS okwana maekala 768 okhala ndi matanki 96 olima omwe amapanga matani 300 a nsomba zapamwamba pachaka, pogwiritsa ntchito madzi ochepera 95% kuposa njira zachikhalidwe. Malo owongolera a digito a dongosololi amagwiritsa ntchito masensa owunikira kuti aziwunika pH, okosijeni wosungunuka, mchere, ndi zizindikiro zina mu thanki iliyonse nthawi yeniyeni, zomwe zimayatsa mpweya wosungunuka pamene okosijeni wosungunuka amatsika pansi pa 6 mg/L. Mtsogoleri wa polojekitiyi anafotokoza kuti: "Mitundu monga ma coral groupers a leopard coral imakhudzidwa kwambiri ndi kusintha kwa okosijeni wosungunuka, zomwe zimapangitsa kuti njira zachikhalidwe zikhale zovuta kukwaniritsa zofunikira zawo zaulimi. Kuwunika molondola masensa owunikira kwatsimikizira kupita patsogolo kwathu pakubereka kopangidwa." Mofananamo, malo olima nsomba ku Gobi Desert ku Aksu, Xinjiang, achita bwino kulima nsomba zapamwamba kwambiri kumtunda, kutali ndi nyanja, zomwe zimapangitsa kuti "zakudya zam'madzi zochokera kuchipululu" zikhale zodabwitsa, zonsezi chifukwa cha ukadaulo wa masensa owunikira.
Kugwiritsa ntchito masensa oyeretsera mpweya wosungunuka kwathandizanso kuti chuma chiziyenda bwino kwambiri. Liu Yuming, mlimi ku Baitan Lake base ku Huanggang, adanenanso kuti atagwiritsa ntchito njira yowunikira mwanzeru, maiwe ake a nsomba okwana maekala 24.8 adatulutsa madzi okwana 40,000 jin, omwe ndi ochulukirapo kuposa chaka chatha. Malinga ndi ziwerengero kuchokera ku kampani yayikulu yoweta nsomba ku Shandong, njira yolondola yopezera mpweya yotsogozedwa ndi masensa oyeretsera idachepetsa ndalama zamagetsi zopezera mpweya ndi pafupifupi 30% pomwe ikukweza kuchuluka kwa chakudya chosinthidwa ndi 15%, zomwe zidapangitsa kuti ndalama zonse zopangira zichepetse ndi 800-1,000 yuan pa tani imodzi ya nsomba.
