1 Te kaupapa matua me te hanganga o te pauna maha-upoko Ko te kaupapa matua o te pauna maha-upoko ko te mea i muri i te utaina o te mea ki te pauna, ka hurihia e te pūoko pauna te tohu taumaha kupenga hei putanga tohu hiko taurite, kātahi ka whakanuia e te pauna maha-upoko, ka tātarihia, ka hurihia e te A/D, ka tukatukahia matihiko te putanga tohu matihiko e te pūoko ka whakaatuhia ki te whakaaturanga. Ka taea te wehewehe i te pauna maha-upoko ki ngā wāhanga e whā, e whakaaturia ana i te Pikitia 1. Ko te kaupapa matua, te hanganga me te tātari tiaki ara iahiko o te ripanga pauna: Tuatahi, ko te wāhanga pūoko pauna, ko tana mahi matua ko te huri i te tohu taumaha kupenga i tāpirihia ki te papa pauna hei putanga tohu hiko ōrau; tuarua, ko te wāhanga whakaaturanga matihiko, ko tana mahi matua ko te whakaatu i te putanga tohu matihiko e te pūoko ki te whakaaturanga i muri i te whakanui, te tātari, te hurihanga A/D me te tukatuka matihiko; tuatoru, ko te wāhanga tinana pauna, ko tana mahi matua ko te uta, ā, ka taea hoki te wehewehe i te pūnaha miihini ki te papa pauna, te pana rohe whakawhiti, me te pūtu gong; kei roto i ngā taputapu hiko he pito, he taura whakawhitiwhiti, me ētahi atu; Tuawhā, ko te wāhanga taha, e pā ana ki ngā taputapu e hono ana ki te putanga tohu o te taputapu whakaatu mamati me te whiwhi i te tohu putanga o te papa taputapu; ko ngā taha noa ko ngā pūreretā, ngā whakaaturanga mata nui, me ngā pūnaha whakahaere atamai rorohiko; hei tāpiri, kei reira te whakaurunga me te putanga anaro, te putanga muka whatu, te putanga whakawhiti waenga, me ētahi atu. Ka taea te wehewehe i te tēpu pauna maha-upoko hiko tauine hiko kia rua ngā wāhanga e ai ki te momo tohu, arā, te tēpu pauna maha-upoko anaro me te tēpu pauna maha-upoko mamati. Te tēpu pauna maha-upoko anaro Ka whiwhi te pauna pauna i ngā tohu mamati, ā, ka whakamahia e te tinana pauna ngā pūoko anaro, e huri ana i te taumaha i tāpirihia ki te tauine hei putanga tohu hiko taurite mā te whakarerekētanga o te tinana rapa hei whakaputa i te ātete o te ine taumaha ātete; ko te pauna maha-upoko mamati he taputapu e whakakotahi ana i te hangarau mōhiohio hiko hou, te hangarau tukatuka-iti, te hangarau utu mamati me ngā pūoko taumaha ine taumaha tuku iho. Ka taea e ia te tatau i te taumaha mā te rorohiko me te whakaatu, te penapena, te tārua me te tuku mā te whakarato i tētahi atanga whakawhitiwhiti kōrero me te kawa e ōrite ana ki te pūoko mamati. 2 Ngā Tikanga Tiaki o ngā Pauna Pauna Maha-Upoko Hiko me ngā Ara Pūoko Ngā Pauna Pauna Maha-Upoko Hiko He maha ngā āhuatanga hapa o ngā tēpu pauna, ā, he maha ngā āhuatanga e puta ai ngā hapa. Ā, he maha ngā take rerekē mō te āhua hapa kotahi. Nā te mea me kimi hapa, me rapu tuatahi tātou me te whakatau i te wāhi o te hapa. Ko te rapu hapa e ahu mai ana i te āhua hapa i whakarāpopototia i te wā o te hapa me ngā mahi a ngā wāhanga pūnaha, ngā taputapu hiko, ngā hononga, me ngā wāhanga. I te whakakotahitanga me ngā momo hapa i whakarāpopototia i te wā o te rapu raruraru noa, ka tirohia, ka tātarihia hoki ngā āhuatanga katoa e puta ai te hapa. Kātahi, mā te whakamahi i te mita maha, te papa taputapu tohu ataata, ka tirohia te tūranga rerekē takitahi, ā, i te mutunga ka whakatauhia te wāhi o te hapa. 2.1 Ngā Raru i puta mai i ngā āhuatanga taiao Ka taea e ngā huringa o ngā āhuatanga taiao te take o te pauna o ngā pauna hiko. Ko ngā āhuatanga matua ko ngā huringa o te pūtake hiko. Te wiri, te tere o te hau, ngā whiunga uira, me ētahi atu, e meinga ai te pauna hiko kia kore e pumau te mahi. Nō reira, me tīmata te pauna hiko kia iti rawa te taea i te wā e hau ana, e whatitiri ana hoki. I taua wā anō, me mahi pai ngā mahi tiaki uira me te whakatūturu i te tauine hiko. Mō te wiri, ka taea te whakamahi i ngā mahi ātete wiri pērā i ngā taputapu ārai me ngā awaawa tiaki hei whakaiti i tōna pānga. Kāore e taea te whakamahi i te pūtake hiko o te pūnaha hiko hei hono motuhake i te tauine hiko, hei whakarerekē rānei i te pūtake hiko kua whakaritea te tawhā. 2.2 Te rahunga o ngā taputapu i te taumata tinana tauine Ko te rahunga o ngā taputapu i te taumata tinana tauine ko te whakarerekētanga o te tautoko tauine, te pēhitanga o te tinana tauine e te paru, te rahunga o ngā taputapu pana rohe, me te rahunga o te tautoko pūoko pauna. He maha ngā wā ka nekehia e ngā tauine hiko ngā rauemi i roto i te whakamahinga roa, ā, ka marara tonu ngā rauemi. Ka tautokona ngā wāhanga miihini mō te wā roa. Ka taea e te kino te kino ngāwari ki ngā wāhanga miihini. Ko ngā rahunga o ngā wāhanga miihini o te tauine hiko ka taea te kite tika ki ngā kanohi, ka taea rānei te tautuhi ngāwari mā te wiri ngāwari o te tinana tauine hei whakakore i ngā hapa. 2.3 Ngā rahunga o te pūoko Ko te pūoko pauna te wāhanga matua o te tauine hiko. Kei a ia te mahi ki te huri i te kaha ki ngā tohu hiko. Ko ngā rahunga o te pūoko pauna ka taea te arahi ngāwari ki ngā peka nui o te taumaha o te tauine hiko. Kāore e taea e te tauine te hoki ki te kore. He nui te rerekētanga o te taumaha o te wira. He ngoikore te āheinga whakahoki, me ētahi atu. 1) Mena he nui te rerekētanga o te pauna o te tauine hiko, tirohia tuatahi mēnā he pumau te uara waehere, mēnā he waku i ia tūranga o te pūoko, mēnā he pumau te pūtake hiko ka taea te whakarite, ā, mēnā he noa te ara iahiko op amp. , whakamahia ngā taumaha paerewa hei tirotiro mēnā he ōrite te taumaha o ngā waewae e whā o te tauine. E ai ki ngā tohutohu, tātarihia anō te papa taputapu, whakatikatika rānei i te taumaha kupenga. 2) Mena kāore e taea e te tauine hiko te hoki ki te kore, tirohia tuatahi mēnā kei roto i te paerewa te uara tohu putanga pūoko (waehere taurangi katoa A/D/awhe waehere tono/awhe waehere raro). Mena kāore te uara tohu i roto i te paerewa, whakatikatikahia te ātete ka taea te whakarite i te pūoko kia whakatikatikahia te uara tohu ki te paerewa. Mena kāore e taea te whakatika, tirohia mēnā he hapa te pūoko. Whai muri i te whakarite he noa te putanga pūoko (he pumau te tinana tauine), rakahia te pumau o te papa taputapu. Mena he hapa, ko te nuinga o te wā ka puta mai i te ara iahiko whakakaha me te ara iahiko whakawhiti A/D. Kātahi, e ai ki te mātāpono o te ara iahiko, me tirotiro tuatahi mēnā he noa te pūtake hiko, kātahi ka hono i te tohu whakauru ki te tohu ataata, ka whakatikatika i te rahi whakauru o te tohu ataata, ka tirohia mēnā he noa te ngaohiko i muri i te whakanui. Kātahi ka whakamahia te oscillator mamati hei tirotiro mēnā kei te oscillate te oscillator tioata hohe, tirohia mēnā he noa te putanga o ia pūwāhi, ā, hei whakamutunga, tirohia te ara iahiko optocoupler me ētahi atu ara iahiko putanga hei kimi i te hapa. 3) He nui te rerekētanga o te taumaha wira o te tauine hiko, he ngoikore rānei te whakahokinga. He rite tēnei āhuatanga ki te āhuatanga o te kore e taea te hoki ki te kore. I te nuinga o te wā, tera pea nā te huringa o te awhe whakauru tohu iti. E ai ki te tikanga o te kore e taea te hoki ki te kore, ki te kore he raruraru i kitea, tirohia tuatahi te pūtake hiko. Mēnā he noa te ara iahiko A/D, kātahi ka tirohia te putanga o te pūoko. Hei tāpiri, ka taea te whakamahi i te tikanga ine hihiri hei tirotiro i te hapa noa o te pūoko. Ko te otinga he hono tika i te waea pūoko ki te papahoahoa, whakamahia te taputapu DCV o te mita matihiko (e whā me te hawhe mati, neke atu rānei te pai), ka ine i te S+ kia rite ai ngā ngaohiko mahi o te whenua me te S- ki te whenua (he pai ake te 0 te rerekētanga)? Ki te kore, me utu te pūoko. Ko te tikanga, ki te teitei rawa te tohu putanga o te pūoko, tāpirihia he ātete taurangi i waenganui i te "E+S-" o te pūoko kia uru te uara tohu ki roto i te awhe noa (ki te iti ake te ātete, ka iti ake te tohu putanga o te pūoko). Ki te iti rawa te tohu putanga o te pūoko, -ERR rānei, tāpirihia he ātete taurangi i waenganui i te "E+~S+" o te pūoko kia uru te uara tohu ki roto i te awhe noa (ki te iti ake te ātete, ka teitei ake te tohu putanga o te pūoko). 2.4 Tauine maha-upoko hiko Ētahi atu hapa me ngā whakatikatika noa o te mita pauna 1) Ina kore e taea te tahuri i te tauine hiko, tirohia tuatahi te pana hiko matua o te tauine hiko, te mono hiko, te pana hurihanga ngaohiko me ētahi atu wāhanga hiko taurite tuku me te tono. Ki te kore he raruraru, tirohia mēnā kei te whakawhiti hiko te whakaurunga AC me te putanga AC. Mēnā he pākahiko kei te papa taputapu, tangohia te pākahiko, kātahi ka tīmata ki te hiko AC kia kore ai e puta he hapa nā te koretake o te ngaohiko pākahiko. Hei whakamutunga, tirohia mēnā he rerekē te ara iahiko whakawhiti, te ara iahiko whakahaere ngaohiko me te ara iahiko optocoupler whakaatu. Mēnā he noa ēnei, tirohia mēnā kua wera te PTM me ngā ara iahiko āwhina. 2) Ka whakaatuhia he waehere hapa e te mata tauine hiko. Tangohia te ara iahiko whakaaturanga taketake ka whakakapia ki tētahi ara iahiko whakaaturanga noa kia kite mēnā he noa. Mēnā he rite te whakaaturanga ki te whakaaturanga o ngā mōhiohio, ko te tikanga he raruraru kei te ara iahiko whakaaturanga. Mēnā he rerekē, tirohia mēnā he hapa kei te ara iahiko optocoupler, ā, hei whakamutunga tirohia mēnā kei roto te pine putanga whakaaturanga PTM i te awhe putanga tika. 3) Kāore te kī mahi e mahi tika ana, kāore rānei e mahi. Tuatahi, tirohia mēnā he turuturu kei te tūranga kī mahi, ka hua ake he ara iahiko poto, he ara iahiko poto rānei; tuarua, tirohia mēnā kei te pai te hononga o te mono kī mahi me te putanga hiko, ā, mēnā he wetewete; tuatoru, tirohia mēnā he pai te hononga o te kī mahi; Tuawhā, tirohia mēnā he ara poto, he ara poto rānei te hononga hiko o te pūhiko hiko me te raina hononga irahiko CPU. Mēnā kāore anō kia kitea te hapa, ko te tuarima ko te ine tika mēnā he ara poto, he ara poto rānei ngā taio me ngā ātete i runga i ngā kī mahi me ngā ara CPU. I roto i te poto, ko te take o te pane maha hiko He maha ngā hapa noa i roto i ngā pauna pauna, ā, he tino uaua hoki ngā āhuatanga hapa. I ētahi wā ka puta he maha ngā hapa i te wā kotahi. He rite tonu ngā pauna pauna maha hiko ki ētahi atu hua hiko. Mēnā ka mārama koe ki ōna mātāpono hanganga me ōna ara iahiko, ka taea e koe te mahi tiaki. I te wā e whakaoti ana i ngā hapa noa o ngā pauna pauna maha hiko, me whakahaere e koe he tātaritanga hohonu i runga i ngā āhuatanga hapa noa, tirohia marietia te wāhanga ka puta ai te hapa noa, tautuhia wawetia te wāhi hapa noa, me te whakarite kia tika te pauna o te pauna pauna maha hiko. Kupu Whakataki: Ki te whakatauritea ki ngā pauna mīhini, he maha ngā painga o ngā pauna pauna maha hiko pēnei i te pauna tere, te whakaaturanga māmā, me te kore e ngawari ki te pakaru. Kei te whānui haere te whakamahinga, ā, kua whakakapia haeretia ngā pauna mīhini. I roto i tēnei pepa, ka matapakihia tuatahitia te hanganga me te mātāpono pauna o ngā pauna pauna maha-upoko hiko i runga i te hononga ki te ao tūturu, kātahi ka matapakihia ngā tikanga tiaki o ngā pauna pauna maha-upoko hiko me ngā ara iahiko e hono ana ki te pūoko. 1 Mātāpono me te hanganga o ngā pauna pauna maha-upoko hiko Ngā pauna pauna maha-upoko hiko Ko te mātāpono taketake o te pauna ko te whai muri i te utaina o te mea ki roto i te pauna, ka hurihia e te pūoko pauna te tohu raraunga taumaha kupenga hei tohu hiko o te putanga ōrau, kātahi ka whakanuia, ka tātarihia, ka tahurihia e te ripanga pauna maha-upoko, ka tukatukahia matihikotia te putanga tohu matihiko e te pūoko, ka whakaatuhia ki te whakaaturanga. Ka taea te wehewehe i te ripanga pauna kia whā ngā wāhanga, e whakaaturia ana i te Pikitia 1.
