Otomatiki vharafu imhando yevharuvhu iyo inogona kugadzirisa otomatiki kuyerera, kudzvanywa, tembiricha uye mamwe ma parameter zvinoenderana nekuchinja kweiyo system parameter, iyo inoshandiswa zvakanyanya mupetroleum, indasitiri yemakemikari, simbi, kuvaka uye mamwe maindasitiri. Iri bepa rinozoongorora iyo inoshanda musimboti uye yekudzora maitiro eiyo otomatiki vharafu kubva kune maviri maficha.
Kutanga, nheyo yekushanda
Nheyo yekushanda yeotomatiki valve inonyanya kuburikidza ne sensor kuona shanduko yemaparamita ehurongwa, chiratidzo chakaonekwa chinoendeswa kune actuator, iyo actuator inogadzirisa kuvhurwa kwevhavha zvinoenderana nechiratidzo, kuitira kuti iwane otomatiki gadziriso yekuyerera. , kudzvinyirira, tembiricha uye mamwe ma parameter.
1 Sensor: Iyo sensor chishandiso chinoshandura huwandu hwakasiyana hwemuviri muhurongwa (senge tembiricha, kudzvanywa, kuyerera, nezvimwewo) kuita masaini emagetsi. Common sensors ndeye thermocouples, thermal resistors, pressure sensors, flow sensors nezvimwe zvakadaro.
2. Actuator: The actuator mudziyo unoshandura zviratidzo zvemagetsi mumagetsi ekufambisa uye inoshandiswa kugadzirisa kuvhura kwevhavha. Common actuators magetsi emagetsi, pneumatic actuators, hydraulic actuators uye zvichingodaro.
3. Valve: Ivhavha chigadziro chinodzora kuyerera, kumanikidza, tembiricha uye mamwe maparamendi emvura yepakati. Mavharuvhu akajairika mavharuvhu epasi, mavharuvhu ekudzora, mavharuvhu ekuchengetedza, mavharuvhu ekuderedza kumanikidza uye zvichingodaro.
2. Kudzora maitiro
Idzo nzira dzekudzora dzeotomatiki mavharuvhu dzinonyanya seizvi:
1. Kuzarura kutonga: Nekushandura kuvhura kwevhavha, gadzirisa kuyerera, kudzvinyirira, kutonhora uye mamwe mapeji emvura. Yakajairika kuvhura yekudzora nzira dzinosanganisira bhuku rekuvhura kudzora, magetsi ekuvhura kudzora, pneumatic kuvhura kutonga uye zvichingodaro.
2. Bit control: kuvhura kwevhavha inodzorwa munzvimbo yakagadziriswa yekudzora kuyerera, kumanikidza, kutonhora uye mamwe maparamita emvura yepakati. Common bit control nzira dzinosanganisira manual bit control, electric bit control, pneumatic bit control zvichingodaro.
3. Kugadziriswa kwekugadzirisa: Nekugadzirisa kuvhurwa kwevhavha, kuyerera, kudzvinyirira, kutonhora uye mamwe mapeji emvura yemvura inogona kuramba ichigadziriswa. Iyo yakajairika nzira dzekudzora dzinosanganisira proportional integral-differential (PID) control, fuzzy control, neural network control uye zvichingodaro.
4. Kudzora kwakangwara: Kuburikidza nekushandiswa kwehunyanzvi hwekugadzira tekinoroji, kuwana hungwaru kutonga kwemaotomatiki mavharuvhu. Nzira dzakajairika dzehungwaru dzekudzora dzinosanganisira nyanzvi system, genetic algorithm, artificial neural network zvichingodaro.
Kupfupisa, musimboti wekushanda weiyo otomatiki vharuvhu ndeyekuona shanduko musystem paramita kuburikidza ne sensor, kuendesa iyo yakaonekwa chiratidzo kune actuator, uye actuator inogadzirisa kuvhurwa kwevhavha zvinoenderana nechiratidzo, kuitira kuti uone otomatiki. kugadziriswa kwekuyerera, kudzvinyirira, tembiricha uye mamwe ma parameter. Nzira dzokudzora dzemavharuvhu otomatiki dzinonyanya kusanganisira kuvhura kudzora, kudzora zvishoma, kudzorwa kwekugadzirisa uye kutonga kwakangwara, etc. Nzira idzi dzekudzora dzinogona kusangana nezvinodiwa zvemavharuvhu otomatiki pasi pemamiriro akasiyana ekushanda.
