Mahele O KEKAHI
1, ʻo ka ʻike ʻana ma o kekahi ala kino, e hoʻokaʻawale i ka helu o nā ʻāpana i ana ʻia i kahi ākea, i mea e hoʻoholo ai inā kūpono nā ʻāpana i ana ʻia a i ʻole ka helu o nā ʻāpana. ʻO ke kaʻina hana o ka hoʻohālikelike ʻana i ka nui ʻike ʻole i ana ʻia me ka nui maʻamau o ke ʻano like, ka hoʻoholo ʻana i ka nui o ka nui maʻamau i ana ʻia e ka hui i ana ʻia, a me ka hōʻike ʻana i kēia helu helu.
Ma ke kahua o ka automation a me ka ʻike, ʻo ka hana o ka ʻike ʻana ʻaʻole wale ka nānā ʻana a me ke ana ʻana o nā huahana i hoʻopau ʻia a i ʻole nā huahana semi-finished, akā no ka nānā ʻana, nānā a mālama i kahi kaʻina hana a i ʻole nā mea neʻe e hana i ka maikaʻi. ke kūlana i koho ʻia e nā kānaka, pono e ʻike a ana i ka nui a me ka hoʻololi ʻana o nā ʻāpana like ʻole i kēlā me kēia manawa. ʻO kēia ʻenehana o ka ʻike manawa maoli a me ke ana ʻana o ke kaʻina hana a me nā mea neʻe i kapa ʻia ʻo ka ʻenehana inspection technology.
ʻElua ʻano ana: ke ana pololei a me ke ana ʻole
ʻO ke ana pololei ke ana i ka waiwai i ana ʻia o ka heluhelu ʻana me ka helu ʻole, e like me: ka hoʻohana ʻana i ka thermometer e ana i ka mahana, me ka hoʻohana ʻana i ka multimeter e ana i ka volta.
ʻO ke ana pololei ʻole ke ana ʻana i nā nui kino pili i ke ana ʻana, a me ka helu ʻana i ka waiwai i ana ʻia ma o ka pilina hana. No ka laʻana, pili ka mana P i ka volta V a me kēia manawa I, ʻo ia hoʻi, P=VI, a ua helu ʻia ka mana ma ke ana ʻana i ka volta a me ke au.
He maʻalahi a maʻalahi ke ana pololei, a hoʻohana pinepine ʻia i ka hana. Eia nō naʻe, inā ʻaʻole hiki ke ana pololei, ʻaʻole kūpono ke ana pololei ʻana a i ʻole nui ka hewa o ke ana pololei, hiki ke hoʻohana ʻia ke ana pololei ʻole.
ʻO ka manaʻo o ka sensor photoelectric a me ka sensor
ʻO ka hana a ka mea ʻike ke hoʻololi i ka nui uila ʻole i loko o ka nui uila e loaʻa ai kahi pilina pili pono, ʻo ia hoʻi ke kikowaena ma waena o ka ʻōnaehana helu uila ʻole a me ka ʻōnaehana helu uila. I ke kaʻina hana o ka ʻike a me ka hoʻokele, ʻo ka sensor kahi mea hoʻololi pono. Mai ka manaʻo o ka ikehu, hiki ke hoʻokaʻawale ʻia ka mea ʻike i ʻelua ʻano: hoʻokahi ka mea hoʻokele mana ikehu, ʻike ʻia hoʻi ʻo ka sensor hana; ʻO ka mea ʻē aʻe ka sensor hoʻololi ikehu, ʻike ʻia hoʻi ʻo ka sensor passive. ʻO ka ikehu mana sensor e pili ana i ka ʻike e ana ʻia i ka hoʻololi ʻana o nā ʻāpana uila (e like me ke kū'ē, capacitance) hoʻololi, pono ka mea ʻike e hoʻohui i kahi lako mana hoihoi, hiki ke ana ʻia nā ʻāpana hoʻololi i ka uila, nā loli o kēia manawa. Hiki i ka ikehu hoʻololi ke hoʻololi pololei i ka hoʻololi i ana ʻia i ka hoʻololi ʻana o ka volta a me ka manawa, me ka ʻole o ka hoʻoulu ʻana o waho.
I nā manawa he nui, ʻaʻole ʻo ka nui uila ʻole e ana ʻia ʻaʻole ke ʻano o ka nui uila ʻole i hiki ke hoʻololi ʻia e ka mea ʻike, pono e hoʻohui i kahi mea hana a mea paha i mua o ka mea ʻike e hiki ke hoʻololi i ka nui uila ʻole i ana ʻia i loko o ka. ka nui ʻole uila i hiki i ka mea ʻike ke loaʻa a hoʻololi. ʻO ka ʻāpana a i ʻole ka mea hiki ke hoʻololi i ke ana ʻole i ka uila i loaʻa he mea ʻike. No ka laʻana, i ke ana ʻana i ka volta me kahi ʻano hoʻopaʻapaʻa kūʻē, pono ia e hoʻopili i ka ʻano kānana i ka mea elastic o ke kaomi kūʻai, e hoʻohuli ka mea elastic i ke kaomi i loko o ka ikaika, a e hoʻololi ke ʻano kānana i ka ikaika i loko o kahi. hoʻololi kūʻē. Eia ka mea ʻike ke kānana, a ʻo ka mea elastic ka mea ʻike. Hiki i ka mea ʻike a me ka mea ʻike ke hoʻololi i ke ana ʻole i ka uila i kēlā me kēia manawa, akā hoʻololi ka mea ʻike i ka mea ʻike ʻole i ka uila i loaʻa i ka uila ʻole, a ʻo ka mea ʻike e hoʻohuli i ka ʻike ʻole i ka uila.
2, ʻike kiʻi uilaua hoʻokumu ʻia ma ka hopena photoelectric, ka hōʻailona kukui i kahi sensor uila uila, hoʻohana nui ʻia i ka mana otometi, aerospace a me ka lekiō a me ke kīwī a me nā kahua ʻē aʻe.
Loaʻa nā mea ʻike kiʻi kiʻi kiʻi kiʻi kiʻi, phototransistors, photoresistors Cds, photocouplers, hoʻoilina photoelectric sensors, photocells a me nā ʻike kiʻi. Hōʻike ʻia kahi papa o nā ʻano nui ma ke kiʻi ma lalo nei. Ma ka hoʻohana pono, pono e koho i ka sensor kūpono e hoʻokō i ka hopena i makemake ʻia. ʻO ke kumu koho maʻamau:ʻike kiʻi uila kiʻekiʻekaapuni, ka laulā ākea o ka mīkini kukui, ka mea ʻike laser ultra-high-speed e koho i ka photodiode; ʻO ka mea maʻalahi pulse photoelectric sensor o kekahi mau tausani Hertz a me ka haʻahaʻa pulse photoelectric hoʻololi i ke kaapuni maʻalahi e koho i ka phototransistor; ʻOiai ua lohi ka wikiwiki o ka pane, ʻo ka mea ʻike alahaka kūpaʻa me ka hana maikaʻi a me ka ʻike photoelectric me ka waiwai kūʻē, ka mea ʻike photoelectric i ke kaapuni kukui ʻakomi o ke kukui alanui, a me ke kūpaʻa hoʻololi e hoʻololi like me ka ikaika o ke kukui e koho. Nā mea kiʻi kiʻi Cds a me Pbs; ʻO nā encoder Rotary, nā mea ʻike wikiwiki a me nā mea ʻike laser kiʻekiʻe kiʻekiʻe e pono e hoʻohui ʻia i nā mea ʻike photoelectric.
