He taputapu nui ngā tuku pehanga e whakamahia whānuitia ana hei ine, hei aroturuki, hei whakahaere hoki i te rerekētanga o te pehanga i roto i ngā hau, ngā wai me ngā wai. He mea nui ēnei hei whakarite i te haumaru, te whai hua, me te pono o ngā tukanga puta noa i ngā rāngai ahumahi maha. He mea nui te mārama ki te putanga o te tuku pehanga mō ngā tohunga hangarau me ngā kaiwhakahaere e whakawhirinaki ana ki ngā pānui pehanga tika i roto i ā rātou mahi.
Ko te tikanga, ka hurihia e te tuku pehanga te tohu i whiwhi mai i te pūoko pehanga whakauru ki te tohu hiko nui ake, ka tukuna atu ki te pūnaha whakahaere (PLC/DCS) hei aroturuki me te whakahaere i te wā tūturu. Ko ngā momo putanga tohu noa ko:
Putanga o nāianei:Ko te momo putanga matua ko te tohu iahiko, he āhua iahiko 4-20 mA te nuinga. He hononga rārangi tō te putanga ki te uara pēhanga e piki haere ana i runga i te pānui pēhanga. Hei tauira, ko te whānuitanga ine o te (0~10) pae ka taea te tohu i te kore ira hei 4mA, ko te pēhanga o te 10 pae e rite ana ki te 20mA e hanga ana i tētahi kauwhata rārangi puta noa i te whānuitanga. Mā tēnei whānuitanga ka taea te whakamārama ngāwari i te uara pēhanga, ā, e whakamahia whānuitia ana i roto i ngā tono ahumahi nā tōna pakari ki te haruru hiko.
Putanga Mamati: Ka taea e ngā tuku pēhanga atamai te whakarato i tētahi putanga matihiko i roto i ngā momo whakawhitiwhiti atamai pēnei i a HART, Modbus-RTU me ētahi atu tikanga. He painga ngā putanga matihiko pēnei i te tika ake, te whakarerekētanga me te tātaritanga i te papaanga, ngā mōhiohio tāpiri e tukuna ana ki te PLS/DCS, me te whakaiti i te ngawari ki te haruru. Kei te piki haere te rongonui o ēnei putanga matihiko atamai i roto i ngā pūnaha aunoatanga hou.
Putanga Ngaohiko:Ka taea e ētahi tuku pehanga te whakarato i te putanga ngaohiko, i te nuinga o te wā i waenga i te 0-5V, i te 0-10V rānei. He iti ake te momo putanga ngaohiko i te porowhita iahiko engari he tino whai hua i roto i ngā tono e pai ake ai ngā tohu ngaohiko mō ngā pūnaha whakahaere.
Putanga Auau:Ko te putanga auau e pā ana ki te huri i ngā pānui pehanga ki te tohu auau. Ahakoa he iti ake te whakamahinga o te tohu auau i roto i ngā tuku pehanga nā te nui o te utu me te uaua o te hangarau, he tino whai hua pea i roto i ngā tono motuhake e hiahiatia ana te tuku raraunga tere-tiketike.
I muri i te whiriwhiri i te tohu putanga tika, me aro atu hoki ki ētahi āhuatanga ka pā ki te putanga i roto i te mahi:
Whakatikatika:He mea nui te whakatikatika tika mō ngā pānui pēhanga tika. Me mahi te whakatikatika wheketere kia tino rite te putanga ki te pēhanga ine tuturu mā te whakatairite i te putanga o te tuku ki tētahi paerewa pēhanga e mōhiotia ana, me te whakarerekē ina tika.
Ngā Pānga o te Pāmahana:Tērā pea ka pā te pāmahana ki te tika o te putanga. Mā te whakatikatika pāmahana wheketere ka āwhina i te whakatika i te pānga pāmahana kāore e hiahiatia ana i te taha o te taiao, engari ka pā tonu te pāmahana tino kino ki te mahi a te tuku. He mea nui kia whiriwhiria he tuku kua whakatauria mō te awhe pāmahana whakahaere motuhake.
Te wiri me te ru:Tērā pea ka puta ngā wiri me ngā ru i ētahi wāhanga i roto i ngā taiao ahumahi, ka hua ake ai he pānui kore pumau me te kino ki te taputapu. He mea nui kia whiriwhiria he hoahoa hanganga pakari e ātete ana ki te wiri, me te whakamahi i ngā tikanga whakaiti wiri e tika ana hei tiaki i te kounga o te taputapu.
Ngā Āhuatanga Waenga:Ka pā anō hoki te āhua o te rauemi ine ki te putanga. Ka rerekē pea ngā āhua o te matū i ngā āhuatanga pēnei i te matotoru, te waikura, me te noho mai o ngā matūriki iri, ā, ka rerekē pea te pānui pēhanga. He mea nui te whiriwhiri i te momo tuku tika e rite ana ki ngā āhuatanga motuhake o te wai ine motuhake kia tika ai te mahi a te taputapu.
Ko ngā momo putanga tohu mai i tētahi tuku pehanga he wāhanga nui o tana mahi. Hei kaihanga taputapu mohio i roto i te rāngai whakahaere tukanga mō ngā tau neke atu i te 20,Shanghai WangyuanE whakarato ana i ngā taputapu ine kua whakamātauhia, pono hoki, me te nui o te wheako ki ngā momo tohu putanga katoa mai i te 4~20mA noa me ngā whakawhitiwhiti atamai ki ngā putanga ritenga. Mena he pātai, he hiahia rānei āu mō ngā putanga tuku, kaua e mangere ki te whakapiri mai ki a mātou.
