1. Kupu Whakataki: Te Otinga Hou mō te Mātauranga Oneone
He taputapu aroturuki whakauru ā-ahumahi te pūoko ngongo oneone RS485, kua hangaia hei tuku raraunga wā-tūturu mō te makuku me te pāmahana oneone puta noa i ngā paparanga poutū maha. Mā te whakamahi i te hangarau Frequency Domain Reflectometry (FDR), ka inehia e ēnei pūoko te pūmau dielectric o te oneone hei tatau i te nui o te wai me te tino tika. He mea nui tēnei hangarau mō te ahuwhenua tino tika o ēnei rā, e whakarato ana i te hononga RS485 Modbus RTU pumau e hiahiatia ana mō ngā pūnaha whakamakuku aunoa, te whakahaere rauemi pumau, me te rangahau taiao mō te wā roa.
2. He aha te Hiranga o te Aroturukitanga Papa-maha mō te Whakamakuku Tika
I roto i te whakahaere rauropi ngaio, kāore i te rawaka ngā raraunga taumata mata. Ka rerekē rawa ngā taumata makuku i te tohu 10cm i ērā i te 40cm, te wāhi e noho ana ngā pakiaka matua. Ko te mārama ki tēnei kōtaha poutū te mea nui ki te whakapai ake i te hua me te hauora o ngā hua.
Te Painga o te Kōtaha Poutū
Ka whakamahia e ā mātou pūoko he hanganga pūwāhi paparua hei whakarato i tētahi tirohanga whānui ki te pou oneone. Mā tēnei hoahoa ka taea e ngā kaihoahoa me ngā kaiwhakatipu te:
3. Te Ruku Hōhonu Hangarau: Te Painga Hangarau a Honde
I roto i ō mātou wheako hei kaihoahoa otinga IoT, ko ngā tino hapa i roto i ngā whakatinanatanga ahuwhenua ko te urunga mai o te taiao me te kore pumau o te hiko. Kua hangaia e mātou te pūoko ngongo oneone Honde RS485 hei whakaiti i ēnei mōrearea mā te whakakī i te kapia epoxy me te whare ahumahi pakari.
Ngā Whakatakotoranga Hangarau: Pūoko Ngongo Oneone Honde RS485

| Hanganga | PVC kaha-teitei; Whakakīia ki te kapia epoxy |
| Whakatauranga Tiakitanga | IP68 (Ka taea te ruku katoa) |
| Te Rahi | Tapeke: 660mm; Rohe Pūrongo: 400mm; Upoko: 184mm; Mata: 76mm |
4. Te Whakauru i te Pūoko Ngongo Oneone RS485 mā te Modbus RTU
Mō te kaihoahoa IoT, he mea nui te pono o te pahi whakawhitiwhiti kōrero, pērā i te tika o te pūoko. Mā te atanga RS485 ka taea te rere taura tawhiti, ahakoa ka tūtohu mātou kia whakamahia he ātete whakamutu 120-ohm mō ngā rere neke atu i te 100 mita hei ārai i te whakaata tohu.
Ngā Whakamāramatanga Waea
Mā te waea paerewa ka taea te whakauru pai ki ngā PLC, ngā RTU, me ngā kuwaha taha:
| Tae | Mahi |
|---|---|
| Whero | Mana Pai (+) |
| Pango | Mana Kino (-) |
| Kōwhai | 485A |
| Kakariki | 485B |
[Whakauruhia te Whakaahua: Kauwhata Hanganga Pūnaha. Kuputuhi-Alternate: He kauwhata e whakaatu ana i ngā pūoko oneone maha e honoa ana mā te RS485 ki roto i te Honde 4G/MQTT Gateway, ka tukuna ngā raraunga ki tētahi tūmau kapua matua.]
Ngā Wāhitau Rēhita Modbus RTU (Paerewa 4-Papa)
Tuhipoka a te Kaihoahoa:Ka whakahokia ngā raraunga hei tauoti 16-bit. Hei whiwhi i te uara tuturu, me wehe te tauoti kua whakahokia mai mā te 100 (hei tauira, ko te pānui o te 2550 e tohu ana i te 25.50%, 25.50℃ rānei).
| Wāhitau | Tawhā | Momo Raraunga | Ngā Wāhanga |
|---|---|---|---|
| 0×0000 | Te Ihirangi Wai Rōrahi (Papa 1 – 10cm) | Kāore i hainatia te hononga | % (Tauoti/100) |
| 0×0001 | Te Pāmahana Oneone (Papa 1 – 10cm) | Waitohu Whakauru | ℃ (Tauoti/100) |
| 0×0002 | Te Ihirangi Wai Rōrahi (Papa 2 – 20cm) | Kāore i hainatia te hononga | % (Tauoti/100) |
| 0×0003 | Te Pāmahana Oneone (Papa 2 – 20cm) | Waitohu Whakauru | ℃ (Tauoti/100) |
| 0×0042 | Wā Tukuatu Hohe | Kāore i hainatia te hononga | Ngā Miniti (0 = Weto; >1 = Ā) |
Haunga te RS485 waea, ka whakaratohia e Honde Technology ngā otinga kuaha 4G me te MQTT whakauru mō ngā kaupapa e hiahia ana ki te whakaaturanga raraunga kapua-ki-pūkoro tika, kāore he hanganga kei te papaanga.
5. SOP Tāutanga: Te Tikanga Parapara Paru
Ko te pai o te pūoko tika ko tōna pānga ki te oneone. Ko te tikanga paru paru te paerewa pai hei whakarite kia pai te hononga i waenga i te ngongo PVC 40mm me te oneone e karapoti ana, kia kore ai he āputa hau.
Hei kaihoahoa whare, ka tohutohu ahau ki ngā kiritaki kia kaua e aro ki ngā haora 24-48 tuatahi o ngā raraunga. Me "tautuhi anō" te oneone, ā, me hoki te paru ki tōna āhua noa i mua i te puta o ngā pānui FDR. Hei tāpiri, karohia te tāutanga i ngā pāmahana i raro i te kore, nā te mea ka whānui te paru tio, ā, ka puta he pānga nui ki te ine.
6. Te Whakatau Rapanga me te Kōwhiringa Pae mō te Pūoko Ngongo Oneone RS485
Ko te whakatakotoranga rautaki te taahiraa whakamutunga hei whakarite i te pono o ngā raraunga mō ngā kaupapa ahuwhenua B2B.
Paearu Kōwhiringa Pae
Ngā Hapa me ngā Otinga Noa
| Hapa | Take Tūpono | Otinga a te Kaihoahoa |
|---|---|---|
| Te Rahunga Whakawhitiwhiti Kōrero | He hē te tere o te mokatere, te wāhitau rānei | Manatokohia te baud (ka taea te tīpako i te 1200–9600, te taunoa 9600) me ngā tautuhinga 8N1. Tirohia te polarity A/B. |
| Raraunga Kore Pūmau | Ngā āputa hau, te kore rānei e pā atu | Whakamahia te tikanga paru hei tango i ngā pute hau e karapoti ana i te ngongo. |
| Kāore he Tukunga Hohe | Rēhita 0×0042 whirihoranga hē | Me whakarite kia whakatakotoria te Rēhita 0×0042 ki te ≥1 (wae: meneti). |
7. Whakamutunga me te Mahi Pakihi
Mā te pūnaha aroturuki oneone whakauru a Honde Technology ka honoa te āputa i waenga i ngā raraunga taiao mata me ngā māramatanga ahuwhenua ka taea te mahi. Mā te whakakotahi i te pūoko FDR tino tika me te pono o te kawa RS485 Modbus RTU, ka whakaratohia e mātou ki ngā kiritaki B2B he otinga tauine, ka taea te ruku, me te iti te mana mō ngā kaupapa whakamakuku tino uaua.
Ahakoa kei te whakauru koe i ēnei pūoko ki roto i tētahi whatunga PLC o nāianei, kei te hiahia rānei koe i tētahi otinga kapua 4G/MQTT katoa, kua rite tā mātou tīma hangarau ki te āwhina.
Whakapai ake i tō mohiotanga oneone i tēnei rā.
