Tātaritanga Whānui o ngā Tohu Taumaha Ārai-Pahūtanga: Ngā Mātāpono, Ngā Āhuatanga, Ngā Whakamahinga, me te Uara Kōwhiringa

Tātaritanga Whānui o ngā Tohu Taumaha Ārai-Pahūtanga: Ngā Mātāpono, Ngā Āhuatanga, Ngā Whakamahinga, me te Uara Kōwhiringa

I roto i ngā rāngai ahumahi mōrearea nui pērā i te hinu, te matū, te waro, me te keri maina, ehara i te mea he mea nui ngā mahi pauna mō te whai huatanga o te whakaputanga anake, engari he mea e pā tika ana ki te haumaru o ngā kaimahi me te mahi. Nā te noho mai o ngā hau mura, ngā hau pahū rānei i roto i ēnei taiao, kāore e taea e ngā taputapu pauna tikanga te whakatutuki i ngā whakaritenga haumaru. Nō reira, kua noho hei mea nui ngā tohu pauna ātete-pahū.

1. He aha te Tohu Taumaha Ārai-Pahū?

He taputapu te tohu pauna ātete-pahū i hangaia mō ngā mahi pauna i roto i ngā taiao mura me ngā taiao pahū. Mā te whakamahi i ngā hanganga, rauemi, me ngā ara iahiko haumaru ātete-pahū, ka whakarite kia kore he mura, he wera, he pewa rānei e puta ai he pahū i te wā e mahi noa ana, i te wā rānei ka hē te mahi.

I te nuinga o te wā ka mahi tahi ēnei tohu me ngā pūtau kawenga ātete-pahū me ngā pouaka hononga, ka hanga he pūnaha pauna ātete-pahū katoa e whakamahia whānuitia ana i roto i ngā raina whakaputa matū, ngā tāke rokiroki hinu, ngā taiao puehu, me ētahi atu wāhi morearea.

2. Te Mātāpono Mahi o ngā Tohu Taumaha Ārai-Pahūtanga

2.1 Te Mātāpono Pūtau Utaina

Ko te pūtau kawenga te wāhanga matua o te tohu pauna ātete-pahū, koia te kawenga mō te huri i te taumaha o tētahi mea (te kaha miihini) hei tohu hiko.

Ko te nuinga o ngā pūtau kawenga hou e whakamahi ana i te hangarau ine taumahatanga:

·Ina tāpirihia te taumaha, ka paku rerekē te āhua o te wāhanga rapa i roto i te pūoko.

·Ka totoro, ka pēhi rānei ngā ine taumahatanga e piri ana ki te wāhanga rapa.

·Ka rerekē te ātete o te ine taumahatanga.

·Ka hurihia tēnei panoni ātete hei tohu hiko taumata-mirivolt mā te piriti Wheatstone.

He rite te tohu putanga ki te taumaha e whakamahia ana, e whakarato ana i te pūtake mō te tukatuka atu.

2.2 Te Tukatuka Tohu me te Whakaaturanga

Ka tukatukahia te tohu anaro ngoikore mai i te pūtau kawenga i roto i te tohu pauna ātete-pahūtanga:

·Whakanui tohu: Ka whakanui i ngā tohu taumata-mirivolt ki tētahi awhe ka taea te kite.

·Te Tātari: Ka whakakore i te haruru e puta mai ana i ngā wiri, i ngā pokanoa rānei o te taiao.

·Te whakarārangi me te whakatikatika: Me whakarite kia ōrite te taumaha e whakaaturia ana ki te taumaha tuturu.

·Te tahuritanga anarau-ki-matihiko (ADC): Ka tahuri i te tohu anarau ki te āhua matihiko.

·Tatau raraunga me te whakaaturanga: Ka whakaaturia te taumaha wā-tūturu ki te whakaaturanga.

Tērā pea ka uru atu ki ngā tauira papai te rokiroki raraunga, ngā mahi whakaemi, ngā whakaoho, me ngā atanga whakawhitiwhiti kōrero.

3. Te Whakatutukitanga o te Mahi Ārai-Pahūtanga

Ko te haumaru o ngā tohu pauna ātete-pahū i roto i ngā taiao morearea e whakawhirinaki ana ki te hoahoa ātete-pahū pūnaha, tae atu ki:

3.1 Hoahoa Hanganga Ārai-Pahūtanga

·Kua hangaia ngā ārai kia tū atu i ngā pēhanga pahūtanga o roto, me te kore e pakaru.

·Ahakoa he hapa o roto, ka āraia te mura kei puta.

3.2 Te Whakamahinga o ngā Rauemi Ārai-Pahūtanga

·He mea hanga noa ngā ārai ki te koranu konumohe, ki te maitai kore waikura rānei.

·He tino pai te ātete o ngā rauemi ki te waikura me te pānga.

3.3 Ngā Ara Hāora Haumaru ā-roto, ā, Ārai Mura hoki

·Kua whakawhāitihia te ngaohiko, te iahiko, me te pūngao hei ārai i ngā pūtake mura.

·Ka whakamahia e ngā wāhanga nui ngā hoahoa ātete ahi, he hoahoa haumaru rānei.

3.4 Te Tiaki Taiao

·Ko te whakatauranga he IP65, he IP67 rānei, kia ātete ai ki te puehu me te wai.

·He pai mō ngā pāmahana tiketike, te haumākū tiketike, me ngā āhuatanga waikura.

4. He aha i hiahiatia ai ngā tohu pauna ātete-pahūtanga

4.1 Ngā Whakaritenga Haumaru

I roto i ngā taiao pahū, ka taea e ngā taputapu hiko noa te pūtake o ngā aituā. Ka whakakorea e ngā tohu pauna ātete-pahū ngā tūponotanga i te pūtake, ka tiaki i ngā kaimahi me ngā taputapu.

4.2 Te Whakapūmau i te Tika

Kāore te hoahoa ātete-pahū e whakararu i te tika o te ine. Mā ngā pūoko tino tika me ngā ADC matatau ka pumau, ka pono hoki ngā hua pauna, ka tutuki hoki i ngā whakaritenga whakaputa me te mana whakahaere kounga.

4.3 Te Whakatutuki i ngā Ture

He maha ngā whenua e whakatinana ana i ngā ture tino pakari mō ngā taputapu e whakamahia ana i ngā wāhi morearea. Mā te whakamahi i ngā taputapu kāore e ātete ki te pahū, ehara i te mea he mōrearea haumaru anake, engari ka hua ake pea he kawenga ture me ngā whiu.

5. Ngā Aratohu Whakahaere

Hei whakarite i te mahi haumaru me te tika:

·Kia maroke, kia ma hoki te tohu, kia kore ai e uru te makuku, te puehu rānei.

·Kaua e neke atu i te kaha kua whakaritea hei ārai i te kino o ngā pūoko me ngā ara iahiko.

· Āraia ngā ru nui, ngā wiri rānei.

·Whakahaerehia ngā kī me ngā mahi e ai ki ngā tohutohu ā-ringa.

·Whakatauritehia i ia wā kia tika ai te pauna.

6. Te Tiaki me te Tiaki

Mā te tiaki tika ka roa ake te ora o te taputapu:

· Horoia te taupoki i ia wā ki ngā rauemi kore-waikura.

·Tirohia ngā hononga me ngā mono mō te wetekina, te tawhito rānei.

·Whakatinanahia he parenga tāpiri i roto i ngā taiao kino.

·Me whakarite kia ārai i te uira me te tūnga whenua i te wā o ngā awha.

·Whakapā atu ki ngā kaimahi whai tohu mō ngā hapa, ngā whakatikatika rānei.

7. Ngā tono ahumahi

7.1 Ahumahi Matū

Whakamahia mō te puranga rauemi mata, te pauna i te tauhohenga, me te ine hua hei whakarite i te haumaru me te hanganga tika.

7.2 Te Hinu me te Hau Māori

Ka aroturuki i te tāke, te paipa, me ngā taumaha uta/tango mō te mahi haumaru me te whakahaere mamao.

7.3 Te Keri me te Ahumahi Waro

E paunatia ana te kohatu, te onepu, me te waro i ngā taiao puehu, uaua hoki.

7.4 Ngā Pūnaha Whakahaere Aunoa

Mā ngā atanga raraunga pēnei i te RS485, PLC, DCS rānei ka taea te kohikohi raraunga aunoa me te whakahaere pokapū.

8. Whakamutunga

Ko ngā tohu pauna ātete-pahū e whakaatu ana i te whakaurunga o te haumaru, te tika, me te tutuki i ngā whakaritenga i roto i ngā mahi taiao morearea. Mā te huri i te taumaha hei tohu hiko mā roto i ngā pūtau kawenga me te whakamahi i ngā hoahoa pakari ātete-pahū me te tukatuka tohu pono, ka whakarite ēnei tohu i te mahi pumau i roto i ngā āhuatanga morearea nui.

I te tipu haere tonu o te aunoatanga ahumahi me ngā whakaritenga haumaru, ka nui haere te mahi nui a ngā tohu pauna ātete-pahūtanga puta noa i ngā ahumahi me ngā tono kanorau.
