Isingeniso senzwa yezinga lokushisa le-infrared
Inzwa yethempelesha ye-infrared iyinzwa engathinteki esebenzisa amandla emisebe ye-infrared ekhishwe into ukukala izinga lokushisa elingaphezulu. Umgomo wayo oyinhloko usekelwe emthethweni we-Stefan-Boltzmann: zonke izinto ezinezinga lokushisa elingaphezu kweqanda eliphelele zizokhipha imisebe ye-infrared, futhi umfutho wemisebe ulingana namandla wesine okushisa okungaphezulu kwento. Inzwa iguqula imisebe ye-infrared etholiwe ibe isignali kagesi ngesitholi se-thermopile esakhelwe ngaphakathi noma i-pyroelectric, bese sibala inani lokushisa nge-algorithm.
Izici zobuchwepheshe:
Isilinganiso esingathintana naye: asikho isidingo sokuxhumana nento elinganiswayo, ukugwema ukungcoliswa noma ukuphazamiseka kwezinga lokushisa eliphezulu kanye nezinhloso ezihambayo.
Isivinini sokuphendula esisheshayo: impendulo ye-millisecond, ilungele ukuqapha izinga lokushisa eliguqukayo.
Ibanga elibanzi: ukumbozwa okujwayelekile -50℃ kuya ku-3000℃ (amamodeli ahlukene ayahluka kakhulu).
Ukuzivumelanisa nezimo okuqinile: kungasetshenziswa ku-vacuum, endaweni ebolayo noma ezimeni zokuphazanyiswa kuka-electromagnetic.
Izinkomba zobuchwepheshe eziyinhloko
Ukunemba kokulinganisa: ±1% noma ±1.5℃ (ibanga lezimboni elisezingeni eliphezulu lingafinyelela ku-±0.3℃)
Ukulungiswa kwe-Emissivity: kusekela okungu-0.1~1.0 okulungisekayo (kulinganiselwe izindawo ezihlukene zezinto)
Ukulungiswa kwe-Optical: Isibonelo, u-30:1 usho ukuthi indawo engu-1cm ububanzi ingakalwa ebangeni elingu-30cm.
Ubude begagasi bempendulo: Okujwayelekile ngu-8~14μm (ifanele izinto ezisezingeni lokushisa elijwayelekile), uhlobo lwamaza amafushane lusetshenziselwa ukutholwa kwezinga lokushisa eliphezulu
Izimo zohlelo lokusebenza ezijwayelekile
1. Ukugcinwa kokubikezela kwemishini yezimboni
Umkhiqizi othile wezimoto ufake izinzwa ze-MLX90614 ze-infrared array kuma-motor bearings, futhi wabikezela amaphutha ngokuqhubeka nokuqapha izinguquko ezithwalayo zezinga lokushisa nokuhlanganisa ama-algorithms e-AI. Idatha esebenzayo ikhombisa ukuthi isixwayiso sokuthwala ukwehluleka kokushisisa ngokweqile amahora angama-72 kusenesikhathi singanciphisa ukulahleka kwesikhathi sokuphumula ngamadola aseMelika angama-230,000 ngonyaka.
2. Uhlelo lokuhlola izinga lokushisa lezokwelapha
Ngesikhathi sobhadane lwango-2020 lwe-COVID-19, kwafakwa izithombe ezishisayo zochungechunge lwe-FLIR T emnyango ophuthumayo wezibhedlela, zathola ukuhlolwa kwezinga lokushisa okungajwayelekile kwabantu abangama-20 ngomzuzwana, ngephutha lokulinganisa izinga lokushisa elingu-≤0.3℃, futhi kuhlanganiswe nobuchwepheshe bokuqashelwa kobuso ukuze kuzuzwe izinga lokushisa elingajwayelekile lokulandela umkhondo wabasebenzi.
3. Ukulawula izinga lokushisa kukagesi wasekhaya ohlakaniphile
Isipheki esisezingeni eliphezulu sokungeniswa sihlanganisa inzwa ye-infrared ye-Melexis MLX90621 ukuze igade ukusatshalaliswa kwezinga lokushisa ngaphansi kwebhodwe ngesikhathi sangempela. Uma kutholwa ukushisa okweqile kwendawo (njengokushisa okungenalutho) kutholwa, amandla ayancipha ngokuzenzakalelayo. Uma kuqhathaniswa nesixazululo sendabuko se-thermocouple, isivinini sokuphendula sokulawula izinga lokushisa sikhuphuka izikhathi ezi-5.
4. Uhlelo lokunisela ngokunemba kwezolimo
Ipulazi kwa-Israel lisebenzisa isithombe esishisayo se-Heimann HTPA32x32 ukuze ligade izinga lokushisa le-canopy yezitshalo futhi lakhe imodeli yokuphefumula esekelwe kumapharamitha emvelo. Uhlelo luzilungisa ngokuzenzakalelayo umthamo wokunisela ngokuconsa, konga amanzi angama-38% esivini ngenkathi kukhulisa ukukhiqizwa ngo-15%.
5. Ukuqapha nge-inthanethi kwezinhlelo zamandla
I-State Grid isebenzisa uchungechunge lwe-Optris PI amathemometha e-infrared aku-inthanethi eziteshini zamandla kagesi aphezulu ukuze ihlole izinga lokushisa lezingxenye ezibalulekile ezifana namajoyinti ebhasi kanye nezivikeli amahora angu-24 ngosuku. Ngo-2022, isiteshi esincane saxwayisa ngempumelelo ngokuthinta kabi izixhumi eziyi-110kV, ukugwema ukuphela kukagesi esifundeni.
Amathrendi entuthuko emisha
Ubuchwepheshe be-Multi-spectral fusion: Hlanganisa ukukalwa kwezinga lokushisa le-infrared nezithombe ezikhanyayo ukuze uthuthukise amakhono okuqaphela okuhlosiwe kuzimo eziyinkimbinkimbi.
Ukuhlaziywa kwenkundla yokushisa kwe-AI: Hlaziya izici zokusabalalisa izinga lokushisa ngokusekelwe ekufundeni okujulile, njengokulebula okuzenzakalelayo kwezindawo ezivuvukalayo emkhakheni wezokwelapha.
I-MEMS miniaturization: Inzwa ye-AS6221 eyethulwe yi-AMS inosayizi ongu-1.5×1.5mm kuphela futhi ingashumeka kumawashi ahlakaniphile ukuze kuqashwe izinga lokushisa lesikhumba.
Ukuhlanganiswa Kwezinto Okungenantambo: I-LoRaWAN protocol ye-infrared yokulinganisa izinga lokushisa ifinyelela ukuqapha okukude kweleveli yekhilomitha, ilungele ukuqapha amapayipi kawoyela
Iziphakamiso zokukhetha
Ulayini wokucubungula ukudla: Beka kuqala amamodeli anezinga lokuvikela le-IP67 nesikhathi sokuphendula <100ms
Ucwaningo lwaselabhorethri: Naka ukulungiswa kwezinga lokushisa elingu-0.01℃ nesixhumi esibonakalayo sokuphuma kwedatha (njenge-USB/I2C)
Izinhlelo zokusebenza zokuvikela umlilo: Khetha izinzwa ezingaqhumi ezinobubanzi obungaphezu kuka-600 ℃, ezifakelwe izihlungi zokungenisa intuthu.
Ngokuthandwa kwe-5G kanye nobuchwepheshe bekhompiyutha onqenqemeni, izinzwa zokushisa kwe-infrared ziyathuthuka zisuka kumathuluzi wokulinganisa owodwa ziye kuma-node ezinzwa ezihlakaniphile, okubonisa amandla amakhulu okusebenza emikhakheni efana ne-Industry 4.0 namadolobha ahlakaniphile.
