Intshayelelo kwi-sensor yobushushu be-infrared
I-infrared temperature sensor yi-non-contact sensor esebenzisa amandla e-infrared radiation akhutshwa yinto ukulinganisa ubushushu bomphezulu. Umgaqo wayo oyintloko usekelwe kumthetho kaStefan-Boltzmann: zonke izinto ezinobushushu obungaphezulu kwe-absolute zero ziya kukhupha imitha ye-infrared, kwaye ubukhali bemitha bulingana namandla esine obushushu bomphezulu wento. I-sensor iguqula imitha ye-infrared efunyenweyo ibe yisignali yombane nge-thermopile eyakhelwe ngaphakathi okanye i-pyroelectric detector, ize ibale ixabiso lobushushu nge-algorithm.
Iimpawu zobugcisa:
Ukulinganisa okungadibaniyo: akukho mfuneko yokuchukumisa into elinganiswayo, ukuphepha ungcoliseko okanye ukuphazamiseka kobushushu obuphezulu kunye neethagethi ezihambayo.
Isantya sokuphendula ngokukhawuleza: impendulo ye-millisecond, ifanelekile ukujonga ubushushu obuguqukayo.
Uluhlu olubanzi: ukugubungela okuqhelekileyo -50℃ ukuya kwi-3000℃ (iimodeli ezahlukeneyo zahlukile kakhulu).
Ukuguquguquka okunamandla: ingasetyenziswa kwindawo engenamoya, kwindawo ekonakalisayo okanye kwiimeko zokuphazamiseka kwe-electromagnetic.
Izalathi zobugcisa eziphambili
Ukuchaneka kokulinganisa: ±1% okanye ±1.5℃ (umgangatho ophezulu wemizi-mveliso ungafikelela ±0.3℃)
Uhlengahlengiso lokukhupha umoya: luxhasa ukulungiswa kwe-0.1 ~ 1.0 (elinganiswe kwiindawo ezahlukeneyo zezinto)
Isisombululo sokubona: Umzekelo, i-30:1 ithetha ukuba indawo enobubanzi obuyi-1cm ingalinganiswa kumgama we-30cm
Ubude bexesha lokuphendula: 8~14μm eqhelekileyo (ifanelekile kwizinto ezikubushushu obuqhelekileyo), uhlobo lwe-short-wave lusetyenziselwa ukufumanisa ubushushu obuphezulu
Amatyala aqhelekileyo okusetyenziswa
1. Ukugcinwa kwangaphambili kwezixhobo zoshishino
Umenzi othile weemoto ufake ii-MLX90614 infrared array sensors kwii-motor bearing, waza waqikelela iimpazamo ngokujonga rhoqo utshintsho lobushushu bee-bearing kunye nokudibanisa ii-algorithms ze-AI. Idatha esebenzayo ibonisa ukuba isilumkiso sokungaphumeleli kobushushu obuphezulu kwiiyure ezingama-72 kwangaphambili sinokunciphisa ilahleko zexesha lokungasebenzi ngeedola zaseMelika ezingama-230,000 ngonyaka.
2. Inkqubo yokuvavanya ubushushu bezonyango
Ngexesha lobhubhane we-COVID-19 ka-2020, imifanekiso yobushushu ye-FLIR T series yathunyelwa emnyango wengxamiseko wezibhedlele, yafikelela ekuhlolweni kobushushu obungaqhelekanga kubantu abangama-20 ngomzuzwana, ngempazamo yokulinganisa ubushushu ye-≤0.3℃, kwaye yadibaniswa netekhnoloji yokuqaphela ubuso ukufezekisa ukulandelwa kobushushu obungaqhelekanga kwabasebenzi.
3. Ulawulo lobushushu bezixhobo zasekhaya ezikrelekrele
Isipheki sokungenisa esikumgangatho ophezulu sidibanisa i-Melexis MLX90621 infrared sensor ukuze ijonge ukusasazwa kobushushu bomgangatho wembiza ngexesha langempela. Xa kufunyenwe ubushushu obuphezulu (njengokutshisa okungenanto), amandla ayancitshiswa ngokuzenzekelayo. Xa kuthelekiswa nesisombululo se-thermocouple sendabuko, isantya sempendulo yokulawula ubushushu siyanda ngokuphindwe ka-5.
4. Inkqubo yokunkcenkceshela ngokuchanekileyo kwezolimo
Ifama yakwaSirayeli isebenzisa umfanekiso we-infrared thermal we-Heimann HTPA32x32 ukujonga ubushushu be-canopy yezityalo kunye nokwakha imodeli yokuphefumla ngokusekelwe kwimida yokusingqongileyo. Le nkqubo ilungisa ngokuzenzekelayo umthamo wokunkcenkceshela nge-drip, igcina i-38% yamanzi kwisidiliya ngelixa inyusa imveliso nge-15%.
5. Ukubeka esweni iinkqubo zamandla kwi-intanethi
I-State Grid isebenzisa ii-thermometers ze-infrared ze-Optris PI kwizikhululo ze-high-voltage ukujonga ubushushu beendawo ezibalulekileyo ezifana namajoyinti e-busbar kunye nee-insulator iiyure ezingama-24 ngosuku. Ngo-2022, isikhululo se-substation salumkisa ngempumelelo ngokunxibelelana kakubi kwezixhumi ze-110kV, nto leyo eyathintela ukucima kombane kwingingqi.
Iindlela ezintsha zophuhliso
