He aha te pūnaha PLC e whakamahia ana i roto i ngā mīhini tākai?

Mō te angitu i roto i te taiao pakihi tere o ēnei rā, he mea nui te whakahaere tukanga pono me te aunoatanga. Ka whakanui ake te mīhini tākai aunoa e hangai ana ki te PLC i te hua o ngā mahi hanga. Mā te PLC, ka māmā ake te whakatū me te whakahaere i ngā mahi uaua. He mea nui ngā pūnaha PLC mō te angitu o te maha o ngā ahumahi, tae atu ki ngā ahumahi tākai, matū, kai, me te tukatuka inu. Pānuihia tonu kia mārama ake ai koe ki te pūnaha PLC me tōna hononga ki ngā mīhini tākai.

He aha te pūnaha PLC?

Ko te PLC he whakarāpopototanga mō te "programmable logic controller," koinei tōna ingoa katoa. Nā te mea kua piki haere te hangarau tākai o nāianei ki te miihini me te aunoa, me tino tika te rahinga o ngā taonga e tākaihia ana, nā te mea he pānga tēnei ki te oranga o te hua me te ōhanga.

Ko te nuinga o ngā wheketere e whakamahi ana i ngā raina huihuinga aunoa katoa i tēnei āhuatanga. He mea nui te pūnaha PLC mō te whakahaere maeneene o tēnei raina huihuinga. Nā te whanaketanga o te hangarau, tata ki ngā hua katoa o ngā kaihanga mīhini tākai matua he papa whakahaere PLC, ā, he māmā ake te whakamahi i ēnei i mua.

Ngā momo PLC

E ai ki te momo putanga e whakaputaina ana e rātou, ka whakarōpūtia ngā PLC penei:

· Putanga pūwhakawhiti

· Putanga Triac

· Putanga whakawhiti

Ngā painga o te pūnaha PLC me te mīhini tākai

I mua, kāore i whakamahia te pūnaha PLC ki te mīhini tākai, pērā i te mīhini hiri ā-ringa. Nō reira, i hiahiatia ētahi atu kaiwhakahaere hei whakarite kia oti te mahi. Ahakoa rā, he tino pouri te mutunga. He nui te wā me te moni i pau.

Heoi, i rerekē katoa i te taenga mai o ngā pūnaha PLC i tāutahia ki roto i te mīhini tākai.

Ināianei, he maha ngā pūnaha aunoa ka taea te mahi tahi me te whai hua ake. Ka taea e koe te whakamahi i te pūnaha PLC hei paunatia tika i ngā hua, kātahi ka tākaihia mō te tuku. Hei tāpiri, he mata whakahaere PLC kei ngā mīhini hei whakarerekē i ngā mea e whai ake nei:

· Te roa o te putea

· Tere

· Ngā pēke mekameka

· Reo me te Waehere

· Te pāmahana

· He nui atu anō

Ka whakawātea i te tangata, ka māmā ake hoki te whakamahi i ngā mea katoa.

Hei tāpiritanga, he roa te hanga o ngā PLC, kia taea ai e rātou te tu atu ki ngā āhuatanga uaua, tae atu ki te wera nui, te hiko e haruru ana, te hau makuku, me te nekehanga wiri. He rerekē ngā kaiwhakahaere arorau i ētahi atu rorohiko nā te mea he nui te tāuru/putanga (I/O) e whakaratohia ana e rātou hei whakahaere me te aroturuki i ngā kaiwhakaoho me ngā pūoko maha.

He maha atu anō ngā painga o te pūnaha PLC ki te mīhini tākai. Ko ētahi o ēnei:

Ngāwari o te whakamahi

Kāore e hiahiatia ana e te tohunga hōtaka rorohiko te tuhi waehere PLC. He māmā noa iho, ā, ka taea e koe te matatau i roto i ētahi wiki. Nā te mea e whakamahia ana:

· Ngā hoahoa arawhata whakahaere whakawhiti

· ngā tauākī whakahau

Hei whakamutunga, he māmā noa iho te mārama me te whakamahi i ngā hoahoa arawhata nā te mea he ātaahua ki te titiro.

Te mahi pono tonu

Ka whakamahia e ngā PLC ngā rorohiko moroiti maramara-kotahi, ā, he tino whakaurua ēnei rorohiko, me ngā ara iahiko tiaki me ngā mahi tātaritanga-whaiaro e whakanui ana i te pono o te pūnaha.

He māmā te tāutanga

He rerekē ki te pūnaha rorohiko, kāore e hiahiatia ana e te tatūnga PLC tētahi rūma rorohiko motuhake, ētahi atu mahi ārai pakari rānei.

He whakanui tere

Nā te mea ka whakatinanahia te mana whakahaere PLC mā te mana whakahaere hōtaka, kāore e taea te whakarite ki te mana whakahaere arorau whakawhiti i runga i te pono, i te tere whakahaere rānei. Nō reira, ka whakanui ake te pūnaha PLC i te tere o tō mīhini mā te whakamahi i ngā tāurunga arorau, atamai.

He otinga iti te utu

Ko ngā pūnaha arorau e hangai ana ki te whakawhiti i ngā raraunga i whakamahia i mua, he tino utu nui i roto i te wā. I whakawhanakehia ngā pūmana arorau ka taea te whakarite hei whakakapi mō ngā pūnaha whakahaere e hangai ana ki te whakawhiti i ngā raraunga.

He rite te utu o tētahi PLC ki te haumitanga kotahi-wā, ā, he nui ngā penapena i runga i ngā pūnaha whakawhiti, inā koa mō te wā rapurongoā, ngā hāora miihini, me ngā utu tāutanga me te tiaki.

Te whanaungatanga o ngā pūnaha PLC me te umanga tākai

E mōhio ana koe, ka aunoatia e ngā pūnaha PLC ngā mīhini tākai; ki te kore he aunoatanga, kāore e taea e te mīhini tākai te tuku i te nui o ngā mea.

E whakamahia whānuitia ana te PLC i roto i te pakihi tākai puta noa i te ao. Ko te ngāwari o te whakahaere e ngā miihini tētahi o ōna painga maha. Ahakoa kua roa ngā pūnaha whakahaere PLC e whakamahia ana, ko te whakatupuranga o nāianei kua hangaia mā te whakamahi i ngā hangarau hou. Ko tētahi tauira o tētahi mīhini e whakamahi ana i tēnei momo pūnaha whakahaere ko tētahi mīhini tākai pauna raina aunoa. Ko te whakauru i tētahi pūnaha whakahaere PLC me te whakarei ake i tōna pai he kaupapa matua mō te nuinga o ngā kaihanga mīhini tākai.

He aha ngā kaihanga mīhini tākai e whakamahi ai i te pūnaha PLC?

He maha ngā take i hangaia ai e te nuinga o ngā kaihanga mīhini tākai ā rātou mīhini e tautoko ana i te pūnaha PLC. Tuatahi, ka kawea mai e ia he aunoatanga ki te wheketere a te kiritaki, ka penapena i ngā hāora mahi, te wā, ngā rauemi mata, me te kaha.

Tuarua, ka whakanui ake i tō putanga mahi, ā, he nui ake ngā hua kei a koe, e rite ana ki te tuku i roto i te wā poto.

Hei whakamutunga, ehara i te mea tino utu nui, ā, ka taea e te kaipakihi hou te hoko ngāwari i tētahi mīhini tākai me ngā āheinga PLC kua hangaia ki roto.

Ētahi atu whakamahinga o ngā pūnaha PLC

He maha ngā momo ahumahi pēnei i te rino me te waka, te waka me te matū, me te hiko, e whakamahi ana i ngā PLC mō ngā kaupapa rerekē. Ka whānui haere te whai huatanga o ngā PLC i te whanaketanga o ngā hangarau e whakamahia ana.

Ka whakamahia hoki te PLC i roto i te umanga kirihou hei whakahaere i te whakarewa werohanga me te pūnaha whakahaere mīhini whakakorikori, te whāngai silo, me ētahi atu tukanga.

Hei whakamutunga, ko ētahi atu mara e whakamahi ana i ngā pūnaha PLC ko:

· Ahumahi karāhe

· Ngā whare hanga sima

· Ngā whare hanga pepa

Whakamutunga
