He aha te Taura Taputapu Ārai, ā, he aha te Hiranga o te Ārai?
- Te Whakautu Tika: He Papa Tiaki mō ngā Tohu Tairongo
Ka pātai tonu te tangata:"He aha te taura taputapu ārai?"
Ko te whakautu māmā:Ko te taura taputapu ārai he taura he paparanga arataki anō — ko te nuinga he pepa konumohe, he whiri parahi, he mea e rua rānei — e takai ana i ngā arataki ārai. Ka mahi tēnei arai hei ārai, hei tiaki i ngā tohu ine tairongo o roto mai i te pokanoa hikohiko o waho (EMI) me te pokanoa auau reo irirangi (RFI).
He aha te Hiranga o te Tiaki:
| Raruraru | Kāore he Parepare | Me te Parepare |
| Ngā motuka me ngā VFD tata | Ka puta te haruru i roto i ngā waea tohu mai i te EMI → ngā pānui pōturi | Ka ārai te parepare i te EMI → tohu ma, pumau |
| Ngā tuku reo irirangi (ngā waea kōrero, ngā pourewa waea pūkoro) | Ngā hononga RFI ki te taura → ngā tohu teka | Ka whakaata/mimitia e te parepare te RFI → raraunga pono |
| Ngā taura e rere whakarara ana ki ngā raina hiko | Ka puta ngā hapa ine i te ngaohiko whakaoho | Ka hurihia e te parepare te haruru i puta mai ki te whenua |
| Ngā taputapu whakarewa e tata ana | Ka whakakino te pokanoa nui i te whakawhitiwhiti kōrero matihiko | Ka tiakina e te parepare ngā tohu whakahaere nui |
| Haruru hikohiko puta noa i te tipu | Ka heke te ōwehenga tohu-ki-haruru → ka heke te tika | Ka pupuri te Shield i te pono o te tohu |
Ko te Whakamutunga:I roto i ngā taiao ahumahi, ka ngoikore ngā taura taputapu kāore i te āraia ki te haruru, ka hē ai ngā koropiko 4-20mA, ka rerekē ai ngā pānui RTD, ā, ka kino hoki ngā whakawhitiwhitinga matihiko pēnei i te RS485, i te Modbus rānei.
I Dingzun Cable,Ka hangaia e mātou ngā taura taputapu whakamarumaru me ngā kōwhiringa whakamarumaru konumohe, whiri, me ngā kōwhiringa whakamarumaru hiato — i whakaritea kia rite ki tō taiao EMI me ngā whakaritenga aro ki te tohu.
- Te Mahi a te Parepare: Te Pūtaiao o te Tiakitanga EMI
Ko te mahi a te parepare mā te aukati i te pūngao hikohiko me te huri i taua pūngao ki te whenua i mua i te taenga atu ki ngā kaiārahi tohu.
