Intangiriro ku buryo bwo kumenya ubushyuhe bwa infrared
Sensor y'ubushyuhe ya infrared ni sensor idakora ikoresha ingufu z'imirasire ya infrared irekurwa n'ikintu kugira ngo ipime ubushyuhe bwo hejuru. Ihame ryayo ry'ingenzi rishingiye ku itegeko rya Stefan-Boltzmann: ibintu byose bifite ubushyuhe buri hejuru ya zeru rwose bizatanga imirasire ya infrared, kandi ubukana bw'imirasire bungana n'imbaraga ya kane y'ubushyuhe bwo hejuru bw'ikintu. Sensor ihindura imirasire ya infrared yakiriwe mo ikimenyetso cy'amashanyarazi binyuze mu gikoresho cyubatswemo cya thermopile cyangwa pyroelectric detector, hanyuma ikabara agaciro k'ubushyuhe binyuze muri algorithm.
Ibiranga tekiniki:
Gupima bidahuye: nta mpamvu yo gukora ku kintu kirimo gupimwa, birinda kwanduzwa cyangwa kubangamira ubushyuhe bwinshi n'intego zigenda.
Umuvuduko w'igisubizo cyihuse: igisubizo cya milisegonda, kibereye mu kugenzura ubushyuhe buhinduka.
Ingano nini: ubushyuhe busanzwe -50℃ kugeza 3000℃ (ubwoko butandukanye buratandukanye cyane).
Guhuza ibintu bikomeye: bishobora gukoreshwa mu bintu bidafite umwuka, ahantu hangiza cyangwa mu bintu bibangamira ingufu z'amashanyarazi.
Ibipimo by'ingenzi bya tekiniki
Ubuziranenge bwo gupima: ± 1% cyangwa ± 1.5℃ (urwego rwo hejuru rw'inganda rushobora kugera kuri ± 0.3℃)
Guhindura imyuka ivamo umwuka: bishyigikira 0.1 ~ 1.0 ishobora guhindurwa (ipimwa ku buso butandukanye bw'ibikoresho)
Ubushobozi bwo kwerekana: Urugero, 30:1 bivuze ko ubuso bwa cm 1 bushobora gupimwa ku ntera ya cm 30
Uburebure bw'umuvuduko: Ubusanzwe 8 ~ 14μm (bukwiriye ibintu biri ku bushyuhe busanzwe), ubwoko bw'umuvuduko mugufi bukoreshwa mu kumenya ubushyuhe bwinshi
Imiterere isanzwe y'ikoreshwa
1. Gutegura ibikorwa byo kubungabunga ibikoresho by'inganda
Hari uruganda rukora imodoka rwashyizeho sensors za MLX90614 infrared array ku mabearings ya moteri, maze ruhanura amakosa binyuze mu gukurikirana buri gihe impinduka z'ubushyuhe bw'amabearings no guhuza algorithms za AI. Amakuru afatika agaragaza ko kumenyesha ko amabearings yananiwe gushyuha amasaha 72 mbere y'igihe bishobora kugabanya igihombo cya 230.000 by'amadolari y'Amerika ku mwaka.
2. Sisitemu yo gupima ubushyuhe bw'abaganga
Mu gihe cy’icyorezo cya COVID-19 cyo mu 2020, amashusho y’ubushyuhe ya FLIR T yashyizwe ku muryango w’ibitaro byihutirwa, apima ubushyuhe budasanzwe ku bantu 20 ku isegonda, hamwe n’ikosa ryo gupima ubushyuhe rya ≤0.3℃, kandi ahuzwa n’ikoranabuhanga ryo kumenya isura kugira ngo hagerwe ku gupima ubushyuhe budasanzwe ku bakozi.
3. Kugenzura ubushyuhe bw'ibikoresho byo mu rugo mu buryo bw'ubwenge
Igikoresho gishyushya cyane gikoresha induction cooker gihuza sensor ya infrared ya Melexis MLX90621 kugira ngo ikurikirane ubushyuhe bw'inyuma y'inkono mu gihe nyacyo. Iyo ubushyuhe bukabije bubonetse (nk'ubushyuhe burimo ubusa) bubonetse, ingufu zihita zigabanuka. Ugereranyije n'uburyo busanzwe bwo gukoresha thermocouple, umuvuduko wo kugenzura ubushyuhe wiyongeraho inshuro 5.
4. Uburyo bwo kuhira mu buryo bunoze mu buhinzi
Ubuhinzi bwo muri Isirayeli bukoresha Heimann HTPA32x32 infrared thermal imager kugira ngo ikurikirane ubushyuhe bw'ibihingwa no kubaka icyitegererezo cy'impinduka zishingiye ku bipimo by'ibidukikije. Iyi sisitemu ihindura ingano y'amazi mu kuhira, ikagabanya 38% by'amazi mu murima w'imizabibu mu gihe yongera umusaruro ho 15%.
5. Gukurikirana imikorere y'amashanyarazi kuri interineti
Ishyirahamwe ry’amashanyarazi rya State Grid rikoresha ibyuma bipima ubushyuhe bya Optris PI mu byuma bipima ubushyuhe bw’ibice by’ingenzi nk’aho bihurira n’ibikoresho bikingira ubushyuhe amasaha 24 ku munsi. Mu 2022, hari ibyuma bipima ubushyuhe byaburiye ko hari ibikoresho bigabanya ubushyuhe bya 110kV bitakora neza, birinda ko umuriro w’amashanyarazi uhagarara mu karere.
Imiterere y'iterambere rigezweho
Ikoranabuhanga rya Multi-spectral fusion: Huza gupima ubushyuhe bwa infrared n'amashusho y'urumuri rugaragara kugira ngo wongere ubushobozi bwo kumenya intego mu bihe bigoye.
Isesengura ry'ubushyuhe bwa AI: Sesengura imiterere y'ubushyuhe bushingiye ku kwiga byimbitse, nko gushyira ibimenyetso mu buryo bwikora ku bice bitera ubushyuhe mu rwego rw'ubuvuzi
MEMS miniaturization: Sensor ya AS6221 yatangijwe na AMS ifite ingano ya 1.5×1.5mm gusa kandi ishobora gushyirwa mu masaha agezweho kugira ngo irebe ubushyuhe bw'uruhu.
Interineti y'ibintu idakoresha umugozi: Insinga zo gupima ubushyuhe za LoRaWAN zikoresha infrared zigenzura ubushyuhe ku rwego rwa kilometero, zikwiriye kugenzura imiyoboro ya peteroli
Ibyifuzo byo guhitamo
Umurongo wo gutunganya ibiribwa: Shyira imbere imiterere ifite urwego rwo kurinda IP67 n'igihe cyo gusubiza <100ms
Ubushakashatsi bwo muri laboratwari: Witondere ubushobozi bwo gusuzuma ubushyuhe bwa 0.01℃ n'uburyo bwo gusohora amakuru (nk'uburyo bwa USB/I2C)
Uburyo bwo kurinda inkongi: Hitamo ibikoresho bipima iturika bifite ubushyuhe burenga 600℃, bifite filters zinjira mu mwotsi
Bitewe no gukurura ikoranabuhanga rya 5G na edge computing, sensors z’ubushyuhe za infrared ziri gutera imbere kuva ku bikoresho bimwe byo gupima kugeza ku byuma bipima neza, bigaragaza ubushobozi bwo gukoresha ibintu byinshi mu nzego nka Industry 4.0 n’imijyi ikoresha ubwenge.
