Kenyelletso ea sensor ea mocheso oa infrared
Sensor ea mocheso oa infrared ke sensor e sa amaneng le motho e sebelisang mahlaseli a mahlaseli a kotsi a hlahisoang ke ntho ho lekanya mocheso o holim'a metsi. Molao-motheo oa eona o ka sehloohong o thehiloe molaong oa Stefan-Boltzmann: lintho tsohle tse nang le mocheso o ka holimo ho zero ka ho feletseng li tla hlahisa mahlaseli a infrared, 'me matla a mahlaseli a lekana le matla a bone a mocheso oa holim'a ntho. Sensor e fetola mahlaseli a infrared a amohelehang hore e be lets'oao la motlakase ka mochine o hahiloeng ka har'a thermopile kapa pyroelectric, ebe o bala boleng ba mocheso ka algorithm.
Lintlha tsa tekheniki:
Tekanyo e sa amaneng le motho: ha ho hlokahale ho ikopanya le ntho e lekantsoeng, ho qoba tšilafalo kapa ho kena-kenana le mocheso o phahameng le lipakane tse tsamaeang.
Lebelo la ho arabela ka potlako: karabo ea millisecond, e loketseng ho shebella mocheso o matla.
Mefuta e mengata e fapaneng: ts'ebetso e tloaelehileng -50 ℃ ho 3000 ℃ (mefuta e fapaneng e fapana haholo).
Ho ikamahanya le maemo ho matla: e ka sebelisoa sebakeng sa vacuum, tikoloho e senyang kapa maemong a tšitiso ea motlakase.
Matšoao a mantlha a tekheniki
Ho nepahala ha tekanyo: ± 1% kapa ± 1.5 ℃ (sekhahla se phahameng sa indasteri se ka fihla ± 0.3 ℃)
Phetoho ea Emissivity: E ts'ehetsa 0.1 ~ 1.0 e feto-fetohang (e lekantsoe bakeng sa libaka tse fapaneng tsa thepa)
Qeto ea Optical: Ka mohlala, 30: 1 e bolela hore sebaka sa bophara ba 1cm se ka lekanyetsoa bohole ba 30cm.
Wavelength ea karabelo: E tloaelehileng 8 ~ 14μm (e loketseng lintho tse mocheso o tloaelehileng), mofuta oa maqhubu a khuts'oane o sebelisoa bakeng sa ho lemoha mocheso o phahameng.
Linyeoe tse tloaelehileng tsa ts'ebeliso
1. Tlhokomelo ea esale pele ea lisebelisoa tsa indasteri
Moetsi ea itseng oa koloi o kentse li-sensor tsa MLX90614 tsa infrared array ho libering tsa makoloi, 'me a bolela liphoso ka ho tsoela pele ho beha leihlo liphetoho tsa mocheso le ho kopanya li-algorithms tsa AI. Lintlha tse sebetsang li bonts'a hore temoso ea ho jara mefokolo e feteletseng lihora tse 72 esale pele e ka fokotsa tahlehelo ea nako ka lidolara tse 230,000 tsa US ka selemo.
2. Tsamaiso ea ho hlahloba mocheso oa bongaka
Nakong ea seoa sa 2020 COVID-19, litšoantšo tse futhumatsang tsa FLIR T li ile tsa kenngoa monyako oa tšohanyetso oa lipetlele, ho fihlela tlhahlobo e sa tloaelehang ea mocheso oa batho ba 20 motsotsoana, ka phoso ea tekanyo ea mocheso ea ≤0.3 ℃, 'me e kopantsoe le theknoloji ea ho lemoha sefahleho ho fihlela boemo bo sa tloaelehang ba basebetsi ba ho latela mocheso.
3. Taolo ea mocheso oa sesebelisoa sa lapeng se bohlale
Moapehi oa maemo a holimo o kopanya sensor ea infrared ea Melexis MLX90621 ho lekola phepelo ea mocheso e tlase ea pitsa ka nako ea nnete. Ha mocheso o feteletseng oa sebakeng seo (joalo ka ho chesa ho se nang letho) o fumanoa, matla a fokotseha ka tsela e iketsang. Ha ho bapisoa le tharollo ea setso ea thermocouple, lebelo la karabelo ea taolo ea mocheso le eketseha ka makhetlo a 5.
4. Mokhoa oa ho nosetsa o nepahetseng oa temo
Polasi naheng ea Israel e sebelisa Heimann HTPA32x32 thermal imager ho lekola mocheso oa canopy ea lijalo le ho aha mofuta oa phepelo o ipapisitseng le maemo a tikoloho. Sistimi e fetola ka bo eona bophahamo ba nosetso ea marotholi, e boloka 38% ea metsi serapeng sa morara ha e ntse e eketsa tlhahiso ka 15%.
5. Tlhokomelo ea marang-rang ea litsamaiso tsa matla
State Grid e sebelisa letoto la li-thermometer tsa infrared tsa Optris PI ka har'a liteishene tse nang le matla a phahameng a matla ho lekola mocheso oa likarolo tsa bohlokoa joalo ka manonyeletso a libese le li-insulators lihora tse 24 ka letsatsi. Ka 2022, seteishene se senyane se ile sa lemosa ka katleho e mpe ea likhokahano tsa 110kV, ho qoba ho khaoha ha motlakase sebakeng.
Mekhoa e mecha ea ntlafatso
Theknoloji ea Multispectral fusion: Kopanya tekanyo ea mocheso oa infrared le litšoantšo tse khanyang ho ntlafatsa bokhoni ba ho lemoha sepheo maemong a rarahaneng.
Tlhahlobo ea lebala la mocheso oa AI: Sekaseka litšoaneleho tsa kabo ea mocheso ho ipapisitsoe le thuto e tebileng, joalo ka ho ngola ka boiketsetso libakeng tsa ts'oaetso lefapheng la bongaka.
MEMS miniaturization: Sensor ea AS6221 e phatlalalitsoeng ke AMS e boholo ba 1.5 × 1.5mm feela 'me e ka kenngoa ka lioache tse bohlale ho hlokomela mocheso oa letlalo.
Khokahano ea lintho tse se nang mohala: LoRaWAN protocol ea tekanyo ea mocheso oa infrared e fihlella ho lekola sebaka sa lik'hilomithara tse hole, tse loketseng tlhahlobo ea lipeipi tsa oli.
Litlhahiso tsa khetho
Mohala oa ho lokisa lijo: Beha pele mefuta e nang le boemo ba ts'ireletso ea IP67 le nako ea karabelo <100ms
Patlisiso ea laboratori: Ela hloko tharollo ea mocheso oa 0.01 ℃ le sebopeho sa tlhahiso ea data (joalo ka USB/I2C)
Lisebelisoa tsa ts'ireletso ea mollo: Khetha li-sensor tse thibelang ho phatloha tse nang le mefuta e fetang 600 ℃, tse nang le li-filters tse kenang mosi.
Ka ho tsebahala ha 5G le mahlale a khomphutha a bohale, li-sensor tsa mocheso oa infrared li ntse li tsoela pele ho tloha ho lisebelisoa tsa tekanyo e le 'ngoe ho ea ho li-node tse bohlale, tse bonts'ang bokhoni bo boholo ba ts'ebeliso masimong a kang Industry 4.0 le litoropo tse bohlale.
