He aha nga rereketanga i waenga i te kaiwhakahaere nekehanga me te plc?
Ko te kaiwhakahaere motini he kaiwhakahaere motuhake hei whakahaere i te aratau mahi o te motini: hei tauira, ko te motini kei te whakahaeretia e te AC contactor e te whakawhiti haere me te motuka e peia te ahanoa kia eke ki runga ki te waahi kua tohua, ka rere ki raro, ka whakamahi ranei. ko te reanga wa hei whakahaere i te motini kia huri pai me te kino, ka huri ranei mo tetahi wa ki te mutu ka huri mo tetahi wa ki te mutu.Ko te whakamahinga o te whakahaere nekehanga i roto i te waahi o nga robots me nga taputapu miihini CNC he uaua ake i tera i roto i nga miihini motuhake, he ahua ngawari ake te ahua o te nekehanga, ka kiia ko te GMC.
Nga ahuatanga o te kaiwhakahaere nekehanga:
(1) He ngawari te hanganga taputapu, whakauruhia te kaiwhakahaere nekehanga ki roto i te pahi PC, hono te raina tohu ka taea te tito o te punaha;
(2) Ka taea te whakamahi i te PC he nui te whanaketanga rorohiko;
(3) Ko te waehere o te rorohiko whakahaere nekehanga he pai te ao me te kawe;
(4) He maha atu nga miihini ka taea te whakahaere i nga mahi whakawhanaketanga, ka taea te mahi whanaketanga kaore he whakangungu nui.
He aha te plc?
Ko te Kaiwhakahaere arorau Papatono (PLC) he punaha hiko mahi aritmetika mamati i hangaia mo te tono i roto i te taiao ahumahi.Ka whakamahia e ia he maharatanga ka taea e ia te pupuri i nga tohutohu hei whakahaere i nga mahi penei i nga mahi arorau, te whakahaere raupapa, te taima, te tatau me nga mahi tauhanga, me nga momo taputapu miihini, nga tikanga whakaputa ranei e whakahaerea ana ma te whakauru mamati me te tairitenga me te whakaputa.
Ko nga ahuatanga o te plc
(1) Te ti'aturiraa teitei.Na te mea ko te nuinga o te PLC e whakamahi ana i te rorohiko moroiti maramara kotahi, he nui te whakaurunga, me te ara iahiko whakamarumaru me te mahi tātari-whaiaro, ka pai ake te pono o te punaha.
(2) He kaupapa ngawari.Ka whakamahia e te kaupapa PLC te hoahoa o te arawhata relay me te korero whakahau, he iti ake te nama i te tohutohu rorohiko moroiti, i tua atu i te PLC waenga me te teitei, ko te PLC iti noa mo te 16. Na te ahua o te ahua o te arawhata me te ngawari, he ngawari. ki te rangatira, ngawari ki te whakamahi, ahakoa kaore e hiahiatia he tohungatanga rorohiko, ka taea te whakarite.
(3) whirihoranga hangore.Na te mea ka tangohia e te PLC te hanganga poraka whare, me whakakotahi noa te kaiwhakamahi, katahi ka taea te whakarereke i te mahi me te tauine o te punaha whakahaere, na reira, ka taea te tono ki tetahi punaha whakahaere.
(4) Whakaotia nga waahanga mahi whakauru / whakaputa.Ko tetahi o nga painga nui o te PLC ko te mea mo nga tohu mara rereke (penei i te DC, AC ranei, te rahinga whakawhiti, te rahinga mamati, te rahinga tairitenga ranei, te ngaohiko, te naianei ranei, me etahi atu), he tauira e hono ana ki nga taputapu mara ahumahi (penei he patene, he whakawhiti, he whakamohio i nga kaiwhakawhiti o naianei, he whakaoho motopaika, he mana whakahaere ranei, me etahi atu) tika, me te hono atu ki te papahoa CPU ma te pahi.
(5) Te whakaurunga ngawari.Ka whakatauritea ki te punaha rorohiko, ko te whakaurunga o te PLC kaore e hiahiatia he ruuma motuhake, kaore ano hoki e hiahiatia he waahanga whakamarumaru kaha.Ina whakamahia, ko te taputapu rapu anake me te tauranga atanga I/O o te kaitahuri me te PLC ka hono tika, katahi ka mahi noa.
(6) Tere tere oma.No te mea kei te whakahaeretia te mana PLC e te mahinga o te hotaka, na, ahakoa tona pono, te tere rere ranei, kaore e taea te whakataurite te mana arorau relay.I nga tau kua pahure ake nei, ko te whakamahinga o te microprocessor, ina koa me te nui o te miihini miihini maramara kotahi, kua tino whakarei ake i te kaha o te PLC, me te rereketanga i waenga i te PLC me te punaha whakahaere rorohiko kei te iti haere, ina koa ko te PLC teitei.
Te rereketanga i waenga i te kaiwhakahaere nekehanga me te plc:
Ko te whakahaere nekehanga ko te mana whakahaere o te motuka hiko me te motuka servo.Ko te hanganga mana ko te tikanga: te taputapu mana + atekōkiri + (stepper or servo) motuka.
Ka taea e te taputapu whakahaere te punaha PLC, ka taea ano he taputapu aunoa motuhake (penei i te kaiwhakahaere nekehanga, te kaari whakahaere nekehanga).Ko te punaha PLC hei taputapu mana, ahakoa he ngawari o te punaha PLC, he rerekee, engari mo te tino tika, penei i te - te whakahaere interpolation, nga whakaritenga tairongo ina he uaua ki te mahi, he tino uaua ranei te kaupapa, a he nui pea te utu. .
Ma te ahunga whakamua me te whakaeminga hangarau, ka puta te kaiwhakahaere nekehanga i te wa tika.Ka whakakoi i etahi mahi whakahaere motini whanui me te motuhake - penei i nga tohutohu whakauru.Ko nga kaiwhakamahi anake me whirihora me te karanga i enei poraka mahi, tohutohu ranei, e whakaiti ana i te uauatanga o te papatono me te whai painga ki te mahi me te utu.
Ka taea hoki te mohio ko te whakamahinga o te PLC he taputapu whakahaere nekehanga noa.Ko te kaiwhakahaere nekehanga he PLC motuhake, he wa katoa mo te whakahaere nekehanga.
