He aha ngā mahi e mahi ana te pouaka tūrama mō ngā pūnaha tukatuka pokapōkai?

Te Tūnga Matua me te Kuhunga Tinana o te Pou Pūtahi

He aha te pou pūtahi i ngā punaha whakapaipai pou waenga?

Ko ngā pouaka tūāpapa ka tuanui hei pūkete arataki mō ia wāhi o te pivot, e whakauru ana i te atawhai kaha ki ngā taiao hāwaru me ngā here rerehua mō ngā motuka. Engari, kāore ēnei he pouaka hononga noa. Ko ngā tauira hōu ake kei te mataara i te totohu mōhio e whakamahia ana i ngā taputapu CT e kōrero nei mātou i mua. Ki te pakaru, ki te hāngai rānei tētahi mea ka hāngai ai ki te torque, ka whakamātau aunoa te punaha kia kaua ai te mate. E kitea ana mai i ngā raraunga umanga i te Pūrongo Rangahau Kaha Mārauri Tuarangi a te tau ki muri, ko ngā māra e whakahou ana ki ēnei pouaka mārama, i kitea he itinga o te 40% i ngā whakamātenga takitahi i te nuinga o ngā tūmau tawhito e horoi ana ki ngā relay noa. He tika tēnā, nā te wehe i ngā raru i mua i te haere tonu, ka penapena kia roa te wā me te moni.

Ngā mahi matua i te whakahaerenga o te punaha me te herekau rere

Ka whakatinana ngā pouaka tūāpapa i ētahi mahi e toru matua:

• Te Whakarahitanga o ngā Motuka : Whakarerekē i ngā tere karu whakahaere tru ngā tikanga CAN bus kia ū ki roto i te 2° o te axis pivot pokapū
• Mātai Mōhiotia : Ka whakauru ngā kaitirotiro CT ka tautohe mōmenta ina neke ake te au i ngā roanga haumaru 15–20%
• Whakarākei Tāone : Whakarerekē i te hoatanga hiko kia taea te eke i ngā pikinga e 30% ana kia kore ai te whakauru ā-ringa

Te tūnga me te hononga ki ngā waeonga o te punaha totohe

Kua tahihia ki te turanga o ia torona, ko ēnei pouaka e hāpai ana ki:

1. Ngā motuka taraiwa trū whatu-kī
2. Ngā kaitirotiro āhuatanga trū te whakawhitinga raraunga RS-485
3. Ngā kainoho matua e whakamahia ana te tātaritanga hiko me te tātaritanga kirua

Ko te tūnga takotoranga taketake e āwhina ana i te urupare ō-ngā-wā-katoa ki ngā tikanga mara, i te wā e manawaritia ana ngā waeonga o roto pērā i ngā kaitiaki tūpongo me ngā kainoho lojiki kaute (PLCs) mai i te waimārie me ngā parapara.

Whakahaere Hiko me te Arataki Mōhiotia

Te wehenga hiko ki ngā mōhiotia whakawhiti

Ko ngā pouaka tūmau hei pūwā whakawhitinga hiko, e tuku ana i te hiko mai i te paparanga arataki matua ki ngā mōhiotia whakawhiti katoa i te roa o te totohe. Kei roto i ēnei pouaka ngā taputapu takahi ara me ngā kaiwhakauru e whakahaere ana i te wehenga hiko mā ngā wāhanga, kia rite tonu te rahi o te volta ki ia mōhiotia, kei te paku rānei ake i te 5 ōrau, ahakoa te wāhi i tu ai ki te punaha whakamau wai. He mea nui tēnei, nā teoreira mēnā ka tēkau te whakahaere volta, ka taea e ngā mōhiotia i tāwhai noa te tīmatanga te mutu i te mahi. Mō ngā mara e nui ake ana i te 500 mita, he mea matua nui te pupuri i te hoatu hiko tūmau kia kaua e pakaru tētahi mea i te wā kore matatau.

Ngā wherenga whakahaere me te tiaki ara mō te aukati i te hiko tino nui

Ko ngā pou kōpae hou ka whai mātai pūkaha paku e uru ana ki ngā anara tīkau pea 300% tere ake i ngā taraka mekanikihia (EDN, 2023), ka wehe tūmatanui i ngā ara herenga kei te haumaru tonu te hiko ki ngā pou kāore i pakaru. Ko te whakamarumaru maha-atarangi e whai mātai ana:

• Ngā kaitirotiro ira e kite ana i ngā takotoranga amp >15% i te turanga tuatahi
• Te whakaputa aunoa mō ngā anara mōrearea roa
• Te hangarau whakatētēnga i ngā herekore arca

Ko tēnei ara takirua e heke iho ana i ngā take pā ki te motuka 62% mō ngā hoahoa ara-tahi anake.

Te tirotiro uta me te aukati i te pakaru o te motuka i raro i te pēhanga

Ko te tirotiro i te torque mā te roa e āwhina ana i te urupare mā te mua ki ngā wāhi herekore i te mara:

1. Ko ngā kaitirotiro kawenga e kite ana i ngā piki ake >20% i te mahi noa
2. Ko ngā kaitirotiro māmā e whakahohe ana i te whakamutu motuka ki ngā taumata 85°C (185°F)
3. Ko ngā tikanga whakauru anuanu e whakamātau ana i te whakauru anuanu i muri i ngā wā 3 meneti kākā

Kāwhai ngā taugata whakamarie i te ora o te mōtuka 43% i ngā oneone kiripaka kei reira ka piki ake te koina o ngā pēpihi e hua ana i te urunga o ngā pārtihikara.

Te hononga ki ngā punaha taraiwa mō te whakarāranga tika o te tūmau

Ko ngā pouaka tūmau e mātai ana me ngā pouaka takirua (he nui noa te take o te 100:1) kia pupuri i te <2° te whakarahinga āngira i waenganui i ngā wātea e tū a tata. Ko ngā mōhini whakautu e whakatika i te RPM mōtuka 8–12 ngā wā ia rerekenga karu, hei whakatika mō:

• Ngā rerekētanga o te whakapakari oneone
• Ngā take tōkotoro karu
• Ngā rerekētanga tokiwai hāmiro

Ko tēnei whakatikatika i te wā-ora e aukati ai i ngā hapa whakarerekētanga wātea e matakitaki ana i te 7–12% o te wai whakapaipai mā te tuku wai anuanu, e based ana ki ngā tārua mara a te ahumahi mai i 2023.

Te Whakawhitinga Kōrero Wā-ora I Waenganui I Ngā Pouaka Tūmau Me Te Kaitekau Pokapū

Ngā Tikanga Tuku Raraunga I Waenganui I Ngā Pouaka Tūmau Me Te Kaitekau

Ko ngā punaha pouaka tūranga o te rā nei e horoi ana mā te huinga CAN, te huinga tōkoro RS-485 rānei hei tuku i ngā korero whakahaere ina tata ki te wā kotahi ia sekene. Ko ēnei ka taea te kōrero mō te pēhea o te mahi a ngā motuka, ko waiwareware te takotoranga o ngā mea katoa, me te wā ka hekenga tētahi mea. He nui ngā kaupapa herehere komunikihana nā te mea ka pupuri i ngā raraunga matua e rere ana mā te tawhiti o te hāpaitia tāraira neke atu rānei i waenganui i ngā wāhanga katoa o te punaha. Me tino tukuna ngā ine i te rere o te wai, ngā tohutohu hōkio rānei kia kore ai e raru. Ko te mea e hāngai ai ēnei punaha ko te āhua o te whakawhitinga kōrero anuanu. I tētahi taha, ka taea e ngā kaimahi te mataara i ngā mea katoa mai i tētahi wāhi pokapoka. Engari i te wā kotahi, ka taea e ngā wāhanga takitahi te whakatau kaupapa kei reira e hiahiatia ana, arā ka tere ake te whakatika i ngā raru ki te kāinga i te nuinga ake i ngā punaha tawhito.

Ko te Whakawhitinga Kōrero Hiko rānei, Mātātoko rānei: Te Pono me te Tino Aronga o te Huinga

Ko ngā whatunga huinga e hono ana i ngā tuhaurangi kūpono me ngā hononga irirangi maru:

• Ngā whatunga koiri (ngā kawhe pēraihana kōpere) ka whakaiti i te roa noa e 40% mō ngā huinga anake irirangi (Irrigation Tech Journal 2023), ā, ka taea te herekenga i te whakamaru iho i ngā tohu mō ngā whakahau matua
• Ngā Pūnaha Korewiri (ngā taiapa 900 MHz/2.4 GHz) e tuku ana i te takotoranga utu-tika mō te takutai whenua tahumaero engari he uaua te tino tohu ki runga i ngā riu neke ake i te 5°

I whakaatu ngā tāruatanga mara i te nuinga o ngā hoahoa huinga e 99.96% te wā e mahi ana te whatunga, āno he pouri, he ua, he whakamaru hoki i ngā taputapu.

Te Kitenga Hapa, Te Pōrini Whakapae, me ngā Tātai Pūnaha

Ko te hangarau CRC e whakamahia ana i konei e pakari ana i ngā hapa o ngā pūkete raraunga i te nuinga o te wā, me ngā tere herenga kei raro ake i te 0.01%. Ko ēnei pouaka pou i hangaia e ngā paerewa IEEE 1646, arā ko kātahi ka whakahaere i ngā raru i te wā e he ana me te paraihe o ngā motuka, i te kore whakauru tika rānei o ngā wāhanga. Ina heke mai te take, ka hokihoki ngā whakamōhiotia mai i ngā pou e here ana ki te punaha whakahaere matua i roto i te 300 miriwhati neke atu rānei. Mēnā ka tino puaki te torque, ka tata ki te 30% te nui ake i te tikanga, ka whakamutu aunoatia te punaha kia kaua ai te mate. Ko tēnei urupare maru nei ka āwhina i te whakahaere kia pai tonu hoki anō i ngā wā e puta mai ana ngā raruraru mōrearea i ngā wā o te tiaki whakapai.

Te Whakautu I Ngā Nekehanga Pou i Roto i Te Tawhā Tuarā

Ko ngā kaupapa here here o te tūhuratanga wā-ā-taima (TSN) e whakauru ana i ngā tere poupou ki roto i te ±2% tikanga, e whakaiti ana i te kawenga tuarangi i te wā o ngā panoni tōtika. I tētahi rangahau 2024 mō te whakapau waima tata, i kitea e TSN kua pai ake te tika o te whakauru pūkaha umanga 28% i te nuinga o ngā tikanga takotoranga, e āwhina ana i ngā panoni tata kaua ko ngā tautohe. Ko te whakauru inaianei he mea matua hei tiaki i te tīrata o te pūkaha—mea matua hei arima i ngā wāhi rongonui, i ngā hēkenga ranei o ngā tipu.

Te Whakarahinga ki te Tāone me te Aronga Mātauranga ki ngā Wero

Te Tātai i te Pikinga me te Tautuhi Tere Aunoa ki runga i te Whenua Kāore nei e Rite

Ko ngā pou tokotoru hōu kei te whai pūkete āhuarangi me ngā tapaite GPS e mōhiotia ai pea ka neke ake te āhuatanga o ngā tōtara i te 15 kīrira, kātahi ka heke iho ngā tere motuka mai i te 30 ki te 50 ōrau anoo pea i runga i ēnei wāhanga tino paku. Ko te putanga? He iti ake te porokotia o ngā karu me te kaha ki te māmā atu ki te māmā i ngā wā katoa o te horohoro, kaua ko te whakauru. E ai ki ngā rangahau i tākarotia ki te pukapuka Sensors o MDPI tau kua pahure ake nei, i kitea e ngā pāmu e whakamahi ana i ēnei punaha tere mātau he heketanga nui i ngā takotoranga tēpeka—e toru hāngai pea te itinga koretake i ngā tauine tere-tūtata e mahi ana ki ngā tōtara ōrite.

Te Tātari i ngā Wero me te Arataki ki ngā Tikanga Pourewa

Ko ngā kaiwhakamaori torque kua tūhono ka whakakorea tūmatanui ina piki ake te uta o te motuka, pērā i ngā rākau i ngaro, i ngā tokotoru, i runga ake i ngā rohe kua tohua (aronga 110–120% o te mōhio nominal). Ko ngā tikanga muri i te pourewa ka whakauru anō i te nekeneke o te tōweri i muri i ngā wā kua roa 90 hēkona, e tuku ana kia taea e ngā kaitūhono te tirotiro ā-remote i ngā take trū ahuatanga kamupene, i ngā paparorohiko ranei.

Te Whakanui i te Tatauranga Mā te Whakarārangitanga Pou e te GPS

Ko ngā pouaka Tūī i te wā oianei e whakamahi ana i te hangarau GPS hei whakaiti i te rere o te tūnga ki roto i ēnei pūnaha pivot pokapō nui, e 60 ki te 80 ōrau te iti ake mō te nuinga i ngā tikanga ā-ringaringa tawhito, kātahi ka ripoatia e ngā hua o MDPI i te tau 2023. Ko ēnei taputapu e whakarato pūrongo tūnga ora ana, kia taea ai te whakarerekē i ia motuka takitahi, kia tika tonu te ara whakapai whakapai. He mea nui tēnei ina toromakia ana ngā whenua kiripaka kei te nui te wai he raru, i te wā anō e mahi ana ki ngā parae hāngai kei te tata te hewa. Ko te tika ake e tiaki ana i ngā kaiwhenua i te 325 miriona galon i ia tau e rere ana, ā, ko te ripoata mai i ngā rangahau mātātoko mō te wā roa.

Telemetara mō te Manaaki Tāpokapoka me te Whakatika Mōmu

Ko ngā kaitirotiro kua huinga atu e tuku ana i ngā panonitanga mō ngā waeine taraiwa, ngā īnenga mōtuka, me te whakamahi hiko ki ngā pātene kapua neke atu i ia 15 ki te 30 sekene. Ina hea ana ngā pēpihi, ina hea ana te parirau, ka tukuna tūmatata ngā panui aunoa ki ngā kaiwhakahaere whenua. I raro i ngā raraunga a Farmonaut mai i te tau ki muri, ko ēnei momo rararu i take ai i te 43 ōrau o te wā kua noho ngoikera ngā punaha kurukuru katoa. I tino nui te putanga mai i te hurihanga mai i te whakatika i ngā mea i muri i te pakaru ki te āki ki ngā rararu i mua i te urupare. Ka roa ake te ora o ngā taputapu mai i te toru ki te rima tau, ā, kāore hoki e hiahiatia ana kia tae mai te kaimahi mōhio anuanu, ka iti ake te maha o ngā karanga ratonga umanga kotahi tuatoru.

Whakanui ake i te Rawa o te Paraka Mā ngā Pūnaha Whakahaere Tūponotia

Kei te tino mātauranga ngā pou pūtaka hōu i ēnei rā. Heoi anō, ko te tere whakapai ake i ngā tikanga kia rite ki te whatu o ngā kaiwhakarato hiko me te tirotiro i te rākau huarere hoki. Arā, ka taea e ia te whakarerekē i te nui o te wai e huri ana ki ia wāhi o te mara e hiahiatia ana. I ētahi whakamātautau i ngā mara karaka i Karikia, i kitea ko ngā kainoho i whakamahi i tēnei aronga, ka mutu rātou i te whakamahi i te 18% iti ake o te pāpaku me te penapena i te 27% iti ake i ngā nama hiko nā te mea kāore he roa te haerenga o ngā pahū. Ko tētahi atu āhuatanga pai ko te ara e whakarerekē ana aunoa te punaha ina huri ana i ērā huringa U-nui i ngā mara. Ka arrengia tēnei i te huringa ki runga i te whenua kotahi anō mōhiotia, ka penapena i te wāhi i waenganui i te 8 ki te 12 ekere ia tau mai i ngā raru whenua pakari e kino ana ki te tipu o ngā taro.
