He Kupu Whakataki ki ngā Pūnaha SCADA
Ko te Mana Whakahaere me te Kohi Raraunga, ko te SCADA rānei te whakarapopototanga, he pūnaha whakahaere e whakamahia whānuitia ana i roto i te ahumahi hei aroturuki, hei kohikohi raraunga, me te whakahaere tika, mamao rānei i ngā tukanga ahumahi. E whakamahia ana te SCADA i roto i ngā momo rāngai, mai i te hanga me te whakaputa hiko ki te maimoatanga wai me te kawe waka.
Hītori me te Whanaketanga o te SCADA
I te tekau tau atu i 1960 i whakawhanakehia tuatahitia ai te SCADA, he rite tonu ki ngā whanaketanga o te hangarau rorohiko me te aunoatanga ahumahi. I te mea ka uaua haere te ahumahi, ka kore e whai hua te whakahaere ā-ringa, ā, me whai pūnaha ka taea te aroturuki me te whakahaere aunoa i ngā mahi, ā, i roto i te huarahi whakauru. I te tīmatanga, i whakamahia te SCADA hei aroturuki i te pūngao hiko , engari i roto i te wā, ka whānui haere ōna tono.
I ngā tau 1980 me 1990, i tino whanake te SCADA nā te whanaketanga o te hangarau whakawhitiwhiti kōrero me ngā whatunga rorohiko. Nā te taenga mai o te ipurangi me ngā kawa whakawhitiwhiti kōrero kua whakapaitia, kua piki ake te whai hua me te pono o ngā pūnaha SCADA. I ēnei rā, nā te taenga mai o te Ipurangi o ngā Mea (IoT), kei te whanake tonu te SCADA ki te whakaurunga matatau ake, e āhei ai te whakahaere whānui me te aroturuki, tae noa ki te ao whānui.
Ngā Wāhanga Matua o te SCADA
He maha ngā wāhanga matua o te SCADA:
1. Ngā Wāhanga Pūmanawa Mamao (RTU): Ko ngā RTU he taputapu pūmārō e whakamahia ana hei kohikohi raraunga mai i ngā taputapu ā-rohe pēnei i ngā pūoko me ngā kaiwhakaoho, ka tukuna atu ki te pokapū whakahaere SCADA. Ka tautokohia hoki e ngā RTU ngā mahi whakahaere mō ngā taputapu e aroturukitia ana.
2. Ngā Kaiwhakahaere Arorau Ka Taea te Whakahōtaka (PLC): He maha ngā wā ka whakamahia ngā PLC i roto i ngā pūnaha SCADA hei whakakapi, hei tāpiri rānei ki ngā RTU nā te mea he ngāwari, he kaha hoki ki te tukatuka i ngā arorau whakahaere uaua.
3. Wāhanga Rokiroki Raraunga me te Tūmau: Ka tukuna ngā raraunga e kohia ana e te RTU me te PLC ki tētahi tūmau matua mā roto i ngā momo kawa whakawhitiwhiti kōrero. Ka rongoa e tēnei tūmau ngā raraunga i ngā wā o mua mō te tātari me te tuku pūrongo.
4. Pūmanawa SCADA: He atanga kaiwhakamahi tēnei e āhei ai ngā kaiwhakahaere ki te aroturuki i ngā pūnaha i te wā tūturu, te tātari raraunga, me te whakahaere i ngā tukanga mā te whakamahi i ngā whakaaturanga whakairoiro, ngā whakaoho, me te pūrongo.
