Te Kaiārahi Katoa ki ngā Pūoko IR: Ngā Momo, Ngā Mātāpono, me ngā Tohutohu Hoko Ngaio
1. Whakamāramatanga Hua & Uara Uho
Ngā pūoko IR he pūrere hiko e kite ana i te hihi pōkākā e whakaputaina ana e ngā ahanoa, ā, ka tahuri hei tohu hiko hei tukatuka. Ko ngā ahanoa whai pāmahana i runga ake i te kore pūmau e whakaputa ana i te hihi pōkākā, he roangaru kei waenga i te rama kitea me te ngaruiti.
Uara Uho Ka whakakitea i roto i ngā wāhi e toru:
- Pūoko Hoapā-Kore: Rapua ngā ūnga me te kore hoapā ōkiko, tino pai mō ngā taiao hauora, mōrearea rānei.
- Urutaunga Taiao: Kāore i pāngia e te rama ā-taiao; E mahi tika ana i te ao, i te pō.
- Utu & tōtika hiko: I whakatauritea ki ngā kāmera, ki te LiDAR rānei, Ka tukuna e ngā pūoko IR he iti iho te utu me te whakapaunga hiko iti rawa, kia tino pai ai mō ngā pūrere IoT hiko-pūhiko.
2. E whā ngā momo pūoko IR matua & Ā rātou Mātāpono Mahi
2.1 Pōkākā Ngoikore (PIR) Pūoko
Te pūoko nekehanga tino pūnoa, Whakamahia whānuitia i roto i ngā pūoho haumarutanga, tīramarama aunoa, me ngā kāinga atamai.
Mātāpono Mahi: He Pūoko PIR Kei roto ko ngā huānga pyroelectric tūhono-rangatū e rua me te tātari (i te nuinga o te wā e whakawaengatia ana i te 8-14μm, tino tairongo ki te hihi pōkākā tangata). I te wā he tangata nekehanga puta noa i te horahanga haurapa, He rerekē te nui o te hihi pōkākā i ngā wā rerekē e whiwhi ana ngā huānga e rua, nā te whakarerekētanga o te ngaohiko huaputa. He tangata tū kāore e whakaoho i te pūoko nā te mea ka tae ngā huānga e rua ki te tauritenga wera. Ka wehewehea e te arotahi Fresnel i mua i te pūoko te wāhi haurapa ki ngā rohe tairongo, matapo hoki, whakarei ake i te tairongotanga.
2.2 Pūoko Thermopile
Ka whakamahia mō te inenga pāmahana whakapā-kore, pēnei i ngā ine mahana pōkākā, ine pirometer ahumahi, me ngā tirotiro pāmahana o te umu ngaruiti.
Mātāpono Mahi: Ko te thermopile he maha ngā thermocouples e honoa ana i roto i te rangatū. Ina whiwhi te pūoko i te hihi pōkākā mai i tētahi ahanoa ūnga, Ka wera te horahanga whakangāwari i te wā e noho tonu ana te horahanga tohutoro ki te pāmahana taiao. Mā tēnei rerekētanga pāmahana e whakaputa i tētahi huaputa ngaohiko mā te rākeitanga Seebeck. E pātahi ana te ngaohiko huaputa ki te pāmahana ūnga. Me te tōkarikari tinana pango, ka taea te tika o te ±0.1°C.
2.3 Pūoko Whakaahua Pōkākā (Kurupae puta noa / whakaata)
Ka whakamahia nuitia mō te tatau ahanoa, haurapa tūnga, me ngā whakakā tatanga, E kitea whānuitia ana i roto i ngā raina whakanao aunoa me ngā faucets atamai.
Mātāpono Mahi: Ka taea ēnei te hohe, te ngoikore rānei. Ko ngā momo hohe tino pūnoa kokurupae puta noa (wehewehea te kaituku me te kaiwhiwhi; whati te kurupae i te ahanoa) mewhakaata (kaituku me te kaiwhiwhi i te taha kotahi; e whakawhirinaki ana ki tētahi whakaata, ki te mata rānei o te ahanoa hei whakaata i te rama IR). He LED pōkākā tata (ko te tikanga 940nm, 850nm rānei) ka noho hei pūtake mārama, i te wā e kitea ana e te phototransistor, photodiode rānei ngā huringa o te kaha o te mārama.
2.4 Pūatahanga Wera Pōkākā
Ka whakamahia hei hanga i ngā atahanga tuari wera, tino nui i roto i ngā arotakenga hiko, haurapa māturu wera hanga, me te patu ahi.
Mātāpono Mahi: Ko te uho o te atahanga wera he Huānga Rererangi Arotahi (FPA), e hia mano ngā ine moroiti. He iti noa iho ia ine moroiti, hanganga piriti whakatārewa e huri ana te ātete i te ngongo i te hihi pōkākā. Ka pānuitia ā-hiko te huringa ātete mō ia pika. I muri i te tukatuka tohu me te mahere tae-pseudo, Ka hangaia he atahanga tuari pāmahana ahu-rua. Ināianei ka tutuki i ngā atahanga wera kāore i te whakamātaotia te nuinga o ngā hiahia arumoni, ahumahi hoki.
3. Ripanga Tauritenga
| Momo | Tikanga | Utu | Te ngawari o te whakamahi | Ngā Taupānga Uho |

- Aroturuki Herenga Taputapu & Ngā Arotakenga Hiko: He pūatahanga wera pōkākā he taonga tino nui. Ngā kōwhiringa taumata-tāurunga: Flir One Pro, Hti HT-102 rānei ($200-$500). Kōeke ngaio: Flir E-series, Fluke Ti-series rānei ($2,000+).
- Ngā Taiao Motuhake: Kimihia he tohu pahūtanga (ATEX/IECEx) ngā tiwhikete haumaru rānei mō ngā wāhi mōrearea pēnei i te hinu me ngā tipu matū.
5. Ngā Pātai Auau (FQ)
Q1: He aha te pūoko PIR e kore ai e aro ki te tangata tū?
He: Ā-hoahoa, Ka urupare anake ngā pūoko PIR kingā huringa o te hihi pōkākā. I te wā e tū ana, Ko ngā huānga pūoko e rua i roto ka tae ki te tauritenga wera, hua hua kore ngaohiko huaputa. Ina neke anake te tangata, ka pā raupapa ngā huānga e rua ki te huringa wera, ka puta mai he tohu pārōnaki. Nō reira, ko te PIR hepūoko nekenga, ehara i te pūoko aroaro. Hei kite i te aroaro tū, Whakaarohia ngā pūoko hihiani, ngā huānga thermopile rānei.
Q2: Me pēhea taku whakapai ake i te āraitanga turituri o tētahi pūoko PIR?
He: Ko ngā pūtake whakararuraru noa ko te rā hāngai, whakawera, Ngā kōhao HVAC, me te hau wera tere. Ngā rongoā: (1) Tāutatia atu te pūoko i ēnei pūtake; (2) Whakamahia he whare ārai huarere me tetātari rama mā; (3) Whakaritea te ineine tairongotanga hei whakaiti i te whiwhinga; (4) Whakatinana arorau whakamanatanga i roto i te pūmanawa (E.g., Me whai keu whai muri maha i mua i te whakaoho).
Q3: Ko tēhea te mea tika ake mō te ine mahana pōkākā: rae, ringaringa?
He: He tika ake te rae. He nui te toto o te rae, ā, he āhua pūmau te pāmahana, e whakaata tata ana i te pāmahana o te tinana uho. E tino pāngia ana te ringa e te pāmahana taiao (mārakerake ki te hau mātao ka nui te whakamātao). I te wā e whakamahi ana i te ine mahana pōkākā, mahi i roto i te pāmahana taiao o te 16°C~35°C (61°F~95°F), whāia te pokapū o te rae mai i te tawhiti o te 3-5 Cm, me te ūkui werawera. I roto i ngā āhuatanga makariri, whanganga ringa i raro i te kākahu. Mā te wawaenga o ngā pānuitanga maha ka whakapai ake i te whaikikotanga.
Q4: He aha te awhe mōrahi o te pūoko whakaahua IR puta noa i te kurupae?
He: Kei te āhua tonu o te hiko ōmata me te hoahoa. He awhe tōtika tō ngā pūoko LED paerewa puta noa i te kurupae 5-20 mita. Ka taea e ngā pūoko mā te kurupae mā te whakamahi i ngā diode taiaho pōkākā te tae atu100 mita ki ngā rau mita, Ka whakamahia nuitia mō te haurapa waka huarahi, mō te parenga paenga whare putunga nui rānei. Hoianō, Me aro atu ngā hua taiaho ki ngā taunahatanga haumaru whatu (Akomanga 1 kei te haumaru; Akomanga 2 ā, i runga ake nei me tūpato). I roto i te mahi, whakaarohia te whakaiti tohu nā te kohu, te puehu rānei.
Q5: He aha te rerekētanga i waenga i ngā atahanga wera pōkākā kāore i te mātao me te pōkākā? Ko tēhea me kōwhiri e au?
He:
- Kāore i whakamātaotia: Whakamahia ngā ine moroiti; kāore he whakamātaotanga cryogenic e hiahiatia ana; utu iti iho ($200-$5,000); taumira iti iho (i te nuinga o te wā 80x60 ki te 640x480); whakaoho tere. E tika ana mō te hanga tātaritanga, arotakenga hiko, me te kitenga pō o waho.
- Kua Whakamātaotia: Me whai cryocooler ā-roto hei whakaheke i te pūoko ki te -200°C (-328°F); tino utu nui ($20,000+); taumira me te tairongotanga tino tiketike; auau tāpare tiketike. Whakamahia mō te hōia, rangahau pūtaiao, me ngā taupānga ahumahi mutunga tiketike (E.g., te kite i ngā turuturu korohū iti). Mō te nuinga o ngā kaingākau me ngā kaiwhakamahi ahumahi whānui, He rawaka te pūatahanga wera kāore i te whakamātaotia.
