Isingeniso senzwa yokushisa ye-infrared
Inzwa yokushisa ye-infrared iyinzwa engaxhumani esebenzisa amandla emisebe ye-infrared akhishwa yinto ukukala izinga lokushisa lobuso. Isimiso sayo esiyinhloko sisekelwe emthethweni kaStefan-Boltzmann: zonke izinto ezinezinga lokushisa elingaphezu kuka-zero ophelele zizokhipha imisebe ye-infrared, futhi ukuqina kwemisebe kuhambisana namandla amane okushisa kobuso bento. Inzwa iguqula imisebe ye-infrared etholiwe ibe isignali kagesi nge-thermopile eyakhelwe ngaphakathi noma i-pyroelectric detector, bese ibala inani lokushisa nge-algorithm.
Izici zobuchwepheshe:
Ukulinganisa okungathintani: asikho isidingo sokuxhumana nento elinganiswayo, ukugwema ukungcola noma ukuphazamiseka kokushisa okuphezulu kanye nezinhloso ezihambayo.
Isivinini sokuphendula okusheshayo: impendulo yamasekhondi ayi-milli, efanelekile ukuqapha izinga lokushisa eliguqukayo.
Ububanzi: ukumbozwa okuvamile -50℃ kuya ku-3000℃ (amamodeli ahlukene ahluka kakhulu).
Ukuzivumelanisa nezimo okunamandla: kungasetshenziswa ezindaweni ezivalekile, ezingcolisayo noma ezimweni zokuphazamiseka kwe-electromagnetic.
Izinkomba zobuchwepheshe eziyinhloko
Ukunemba kokulinganisa: ±1% noma ±1.5℃ (izinga lezimboni eliphezulu lingafinyelela ±0.3℃)
Ukulungiswa kokukhishwa komoya: kusekela ukulungiswa okungu-0.1 ~ 1.0 (okulinganiswe ezindaweni ezahlukene zezinto)
Isixazululo sokubona: Isibonelo, u-30:1 usho ukuthi indawo enobubanzi obungu-1cm ingalinganiswa ebangeni elingama-30cm
Ubude besikhathi sokuphendula: Okuvamile okungu-8 ~ 14μm (kufanele izinto ezisezingeni lokushisa elijwayelekile), uhlobo lwamagagasi amafushane lusetshenziselwa ukuthola izinga lokushisa eliphezulu
Amacala okusetshenziswa ajwayelekile
1. Ukulungiswa kwangaphambili kwemishini yezimboni
Umkhiqizi othile wezimoto ufake izinzwa ze-MLX90614 infrared array kuma-motor bearings, futhi wabikezela amaphutha ngokuqhubeka nokuqapha izinguquko zokushisa kwama-bearings nokuhlanganisa ama-algorithms e-AI. Idatha esebenzayo ikhombisa ukuthi isixwayiso sokwehluleka kokushisa kwama-bearings amahora angu-72 kusengaphambili singanciphisa ukulahlekelwa kwesikhathi sokungasebenzi ngamadola aseMelika angu-230,000 ngonyaka.
2. Uhlelo lokuhlola izinga lokushisa kwezokwelapha
Ngesikhathi sobhubhane lwe-COVID-19 lwango-2020, izithombe zokushisa ze-FLIR T series zafakwa emnyango ophuthumayo wezibhedlela, zafinyelela ekuhlolweni kokushisa okungajwayelekile kwabantu abangu-20 ngomzuzwana, ngephutha lokulinganisa izinga lokushisa elingu-≤0.3℃, futhi zahlanganiswa nobuchwepheshe bokubona ubuso ukuze kufezwe ukulandelwa kwezindlela zokushisa ezingajwayelekile zabasebenzi.
3. Ukulawula izinga lokushisa kwemishini yasekhaya okuhlakaniphile
Isipheki sokushisa esiphezulu sihlanganisa inzwa ye-infrared ye-Melexis MLX90621 ukuqapha ukusatshalaliswa kwezinga lokushisa phansi kwebhodwe ngesikhathi sangempela. Uma kutholwa ukushisa ngokweqile kwendawo (njengokushisa okungenalutho), amandla ancishiswa ngokuzenzakalelayo. Uma kuqhathaniswa nesisombululo sendabuko se-thermocouple, isivinini sempendulo yokulawula izinga lokushisa sanda ngokuphindwe kahlanu.
4. Uhlelo lokunisela ngokunemba kwezolimo
Ipulazi e-Israel lisebenzisa i-Heimann HTPA32x32 infrared thermal imager ukuqapha izinga lokushisa le-canopy yezitshalo nokwakha imodeli yokuphefumula ngokusekelwe kumingcele yemvelo. Uhlelo lulungisa ngokuzenzakalelayo ivolumu yokunisela ngokuconsa, longe u-38% wamanzi esivini ngenkathi lukhulisa umkhiqizo ngo-15%.
5. Ukuqapha izinhlelo zamandla ku-inthanethi
I-State Grid isebenzisa ama-thermometer e-infrared e-Optris PI ochungechungeni lwe-infrared eziteshini ezincane ezine-voltage ephezulu ukuqapha izinga lokushisa kwezingxenye ezibalulekile njengezindawo zokuxhuma ama-busbar kanye nama-insulator amahora angama-24 ngosuku. Ngo-2022, isiteshi esincane saxwayisa ngempumelelo ngokuthintana kabi kwama-disconnector angu-110kV, okugwema ukucima kukagesi esifundeni.
Izitayela zentuthuko ezintsha
Ubuchwepheshe bokuhlanganisa ama-spectral amaningi: Hlanganisa ukulinganisa izinga lokushisa le-infrared nezithombe zokukhanya okubonakalayo ukuze uthuthukise amakhono okubona okuqondiwe ezimweni eziyinkimbinkimbi
Ukuhlaziywa kwensimu yokushisa ye-AI: Hlaziya izici zokusatshalaliswa kokushisa ngokusekelwe ekufundeni okujulile, njengokulebula okuzenzakalelayo kwezindawo ezivuvukalayo emkhakheni wezokwelapha
Ukwenziwa kwe-MEMS kube kuncane: Inzwa ye-AS6221 eyethulwe yi-AMS inobukhulu obungu-1.5×1.5mm kuphela futhi ingafakwa emawashini ahlakaniphile ukuze iqaphe izinga lokushisa lesikhumba
Ukuhlanganiswa kwe-inthanethi yezinto ezingenantambo: Ama-node okulinganisa izinga lokushisa le-infrared protocol e-LoRaWAN afinyelela ukuqapha okukude kwezinga lekhilomitha, afanele ukuqapha amapayipi kawoyela
Iziphakamiso zokukhetha
Umugqa wokucubungula ukudla: Beka phambili amamodeli anezinga lokuvikelwa kwe-IP67 nesikhathi sokuphendula <100ms
Ucwaningo lwelabhorethri: Naka ukulungiswa kwezinga lokushisa elingu-0.01℃ kanye nesixhumi esibonakalayo sokukhipha idatha (njenge-USB/I2C)
Izinhlelo zokuvikela umlilo: Khetha izinzwa ezingaqhumi ezinobubanzi obungaphezu kuka-600℃, ezifakwe izihlungi zokungena kwentuthu
Ngokuthandwa kobuchwepheshe be-5G kanye ne-edge computing, izinzwa zokushisa ze-infrared ziyathuthuka kusukela kumathuluzi okulinganisa owodwa kuya kuma-node okuzwa ahlakaniphile, okubonisa amandla amakhulu okusebenzisa emikhakheni efana ne-Industry 4.0 kanye namadolobha ahlakaniphile.
