Kubva yekutanga programmable controller (PC) yakaunzwa muUnited States muna 1969, yakashandiswa zvakanyanya mukutonga kwemaindasitiri.Mumakore achangopfuura, China yakawedzera kutora PC kutonga mumagetsi ekutonga kwemidziyo mupetroleum, makemikari, muchina, indasitiri yemagetsi, kugadzirwa kwemagetsi, zvemagetsi, rabha, maindasitiri ekugadzira mapurasitiki, uye yakawana mhedzisiro inoshamisa.Kugamuchirwa kune ese maindasitiri.Fekitori yedu yakatanga kuisa iyo programmable controller kumuchina wevulcanizing muna 1988, uye kushandiswa kwanga kuri kwakanaka.Tora iyo OMRON C200H programmable controller semuenzaniso wekukurukura mashandisirwo ePC muvulcanizer.
1 Zvimiro zveC200H Programmable Controller
(1) Iyo sisitimu inochinjika.
(2) Kuvimbika kwepamusoro, kushanda kwakasimba kunopesana nekupindira uye kugadzikana kwezvakatipoteredza.
(3) Kushanda kwakasimba.
(4) Mirayiridzo yakapfuma, inokurumidza, inokurumidza uye iri nyore kuronga.
(5) Yakasimba kukanganisa kukanganisa kugona uye kuzviongorora basa.
(6) Mabasa ekutaurirana akasiyana.
2 Zvakanakira kushandisa chinogadzirika chinodzora pane vulcanizer
(1) Midziyo yekupinza yakapfava uye wiring yadzo, senge universal transfer switch, mabhatani, nezvimwe zvinogona kurerutswa kubva mumubatanidzwa wakaoma wemapoka akawanda kuenda kuboka rimwe chete.Iyo wiring yemagetsi switch, mabhatani, nezvimwewo inogona kubatanidzwa kune imwe chete seti yevanobatika (kazhinji yakavhurika kana yakavharika yakavharwa), uye imwe nyika inogona kuzivikanwa mukati nePC, iyo inoderedza zvakanyanya zita re wiring reiyo peripheral mudziyo.
(2) Tsiva waya inorereka yerelay nesoftware.Zviri nyore kuchinja kudzora zvinodiwa.Iyo PC inotora microcomputer-yakavakirwa yemagetsi dunhu, inova musanganiswa weakasiyana emagetsi relay, nguva uye macounter.Kubatana pakati pavo (kureva wiring yemukati) kunoitwa nemugadziri wekuraira.Kana ikashandurwa maererano nezvinodiwa saiti Kudzora maitiro, shandura dunhu rekutonga, ingoshandisa programmer kugadzirisa mirairo, zviri nyore kwazvo.
(3) Kushandiswa kwezvikamu zve semiconductor kushandura kubata kwekutonga kweiyo relay kune isiri-contact control yePC yakagadziridzwa zvakanyanya.J inovimba nekugadzikana kwechikamu, uye kutadza kweiyo relay yepakutanga relay disc inodzorwa, sekutadza kweiyo relay coil burnout, iyo coil inonamira, iyo grid yekukodzera haina kusimba, uye kusangana kwakadzimwa.
(4) Kuwedzera I / 0 Nzara ine mhando mbiri dzekugovera magetsi: 1 inoshandisa 100 ~ 120VAC kana 200 ~ 240VAC magetsi;2 shandisa 24VDC magetsi.Midziyo yekupinza yakadai semabhatani, ma switch switch, ma switch ekufamba, anodzvanya regulators, nezvimwe zvinogona kushandiswa sechiratidzo sosi ye 24VDC magetsi ekupa, iyo inogona kudzivirira kupfupi kutenderera kweiyo switch, pressure regulator, zvichingodaro nekuda kwekushisa kwakanyanya mukugadzirwa. nharaunda, uye kuvandudza kuchengetedzwa kwevashandi vekuchengetedza., basa rakaderedzwa rekugadzirisa.Iyo inobuda terminal inogona kutyaira zvakananga kuburitsa kweiyo solenoid valve uye contactor kuburikidza ne200-240VDC magetsi.
(5) Pamusoro peCPU kukanganisa, kukanganisa bhatiri, scan time kukanganisa, ndangariro kukanganisa, Hostink kukanganisa, kure kure I / O kukanganisa uye mamwe mabasa ekuzviongorora uye anogona kutonga PC pachayo, inoenderana nenzvimbo yega yega I / O Ikoko. chiratidzo chechiratidzo chinoratidza iyo 0N/OFF mamiriro eI/0.Zvinoenderana nekuratidzwa kweiyo I / O chiratidzo, kukanganisa kwePC peripheral mudziyo unogona kutongwa nemazvo uye nekukurumidza.
(6) Zvinoenderana nezvinodiwa zvekutonga, zviri nyore kuvaka iyo yakanyanya kukodzera sisitimu uye kufambisa kuwedzera.Kana iyo vulcanizer ichida kuwedzera nekuvandudza iyo yekudzora dhizaini, wedzera zvikamu zvekuwedzera paCPU huru, uye zvishandiso zvinoda kuvezwa gare gare, izvo zvinogona nyore kuumba sisitimu.
3 Maitiro ekuronga iyo vulcanizer
(1) Simbisa zviito zvinofanirwa kuitwa mukati menguva yese yekushanda kwevulcanizer, uye hukama pakati pavo.
(2) Sarudza huwandu hwemapoinzi ekuisa anodiwa kune inoburitsa switch kutumira iyo yekuisa chiratidzo kune yekupinza mudziyo wePC;iyo solenoid vharafu, iyo contactor, nezvimwewo sehuwandu hwemapoinzi ekubuda anodiwa kuti ugamuchire mudziyo wekubuda kubva kuPC yekubuda chiratidzo.Wobva wapa I/O bit kune yega yega yekupinza uye yekubuda poindi uchigovera "Internal Relay" (IR) kana bhiti rebasa uye timer/counter.
(3) Dhirowa dhayagiramu yemanera zvichienderana nehukama pakati pezvishandiso zvinobuda uye kurongeka (kana nguva) iyo chinhu chekutonga chinofanira kushandiswa.
(4) Kana ukashandisa GPC (Graphics Programmer), FIT (Factory Intelligent Terminal) kana LSS (IBMXTAT Programming Software) inogona kugadzirisa zvakananga purogiramu yePC ine manera ane musoro, asi kana ukashandisa purogiramu yakajairwa, unofanira kushandura dhayagiramu yemanera kuti help.Chiratidzo (chinoumbwa nekero, rairo, uye data).
(5) Shandisa purogiramu kana GPC kutarisa purogiramu uye kugadzirisa kukanganisa, wozoedza purogiramu, uye ona kana kushanda kwevulcanizer kunoenderana nezvatinoda, uye wozogadzirisa purogiramu kusvikira purogiramu yakakwana.
4 Zvakajairwa kutadza kwe vulcanizing muchina otomatiki control system
Mwero wekutadza wevulcanizer inodzorwa nePC yakadzikira, uye kutadza kunowanzoitika zvakanyanya mune zvinotevera zvinhu.
(1) Kupinza mudziyo
Kufanana neshanduko yekurohwa, bhatani, uye chinja, mushure mekuita zvakadzokororwa, inoburitsa kusununguka, kusagadzika patsva, nezvimwe, uye zvimwe zvinogona kukuvara.
(2) Chigadzirwa chekubuda
Nekuda kwekunyorova kwezvakatipoteredza uye kubuda kwepombi, iyo solenoid valve yakafashama, pfupi pfupi inoitika, uye solenoid valve inopiswa kunze.Masignal lights anowanzo kupiswa.
(3) PC
Nekuda kweakawanda mapfupi edunhu echishandiso chinobuda, yakakwira ikozvino inogadzirwa, iyo inokanganisa iyo inoburitsa relay mukati mePC, uye inoburitsa relay contacts inonyungudutswa uye inonamatirwa pamwechete, ichikuvadza relay.
5 Kuchengeta uye kutarisira
(1) Paunenge uchiisa PC, inofanira kuchengetedzwa kubva kune inotevera nharaunda: gasi rinoparadza;kuchinja kwakanyanya kwekushisa;zuva rakananga;guruva, munyu uye upfu hwesimbi.
(2) Kushandisa nguva dzose kunofanira kuongororwa nguva dzose, sezvo zvimwe zvinoshandiswa (zvakadai seinishuwarenzi, relays uye mabhatiri) zvinoda kuchinjwa kakawanda.
(3) Boka rega rega remayuniti ekubuda richabuda ne220VAC, uye inokwana imwe 2A250VAC fuse ichawedzerwa.Kana fuse ichiridzwa, zvinodikanwa kutarisa kana zvigadzirwa zveboka zvakasiyana.Kana iwe ukasatarisa uye nekukasira kutsiva iyo inishuwarenzi nyowani, inokuvadza nyore relay yeinobuda unit.
(4) Teerera kutarisa bhatiri alarm chiratidzo.Kana mwenje wearamu ukapenya, bhatiri rinofanira kutsiviwa mukati mevhiki imwe (tsiva bhatiri mukati me5 maminetsi), uye avhareji yehupenyu hwebhatiri makore mashanu (pasi pekamuri tembiricha iri pasi pe25 ° C).
(5) Kana iyo CPU uye yakawedzerwa magetsi emagetsi abviswa uye akagadziriswa, wiring inofanira kubatanidzwa kana wiring yaiswa.Zvikasadaro, zviri nyore kupisa iyo CPU uye kuwedzera simba rekupa.
