Kuisa masaini anoparadzanisa makabati ePLC

Munyaya yekushanda kwemaindasitiri otomatiki, makabati ekudzora ePLC (Programmable Logic Controller) anoita basa rakakosha, anotarisira kugamuchira masaini kubva kumasensa akasiyana-siyana nema actuator, uye kuwana kutonga kwakaringana kwemaitiro ekugadzira kuburikidza nekushanda kwemukati melogic. Zvisinei, mumashandisirwo anoshanda, makabati ekudzora ePLC anowanzo sangana nemamiriro akasiyana-siyana emagetsi akaomarara uye matambudziko ekupindira kwechiratidzo, izvo zvinogona kutungamira mukusashanda zvakanaka kwesystem yekudzora, kutadza kushanda nguva nenguva, uye kutoisa njodzi kukuchengetedzwa kwemidziyo nevashandi. Nokudaro, kuwedzera chiratidzo chakaparadzaniswamaator kuenda kumakabati ekudzora ePLC ave mhinduro yakajairika.

Mabasa makuru ezviratidzi zvemagetsi anosanganisira kudzivirira kutapurirana kwekupindirana kwemagetsi, kuderedza kuitika kwekukundikana kwehurongwa, uye kupa kupatsanurwa kana michina ikatadza kushanda panzvimbo, kudzivirira kupararira kwezvikanganiso kune system yese yekudzora. Nekugadzirisa nekushandura zviratidzo zvinogamuchirwa nePLC kuburikidza nemidziyo ye semiconductor, wozozviparadzanisa nekushandura uchishandisa michina yekuona kana yemagnetic sensing, uye pakupedzisira kuzvibvisa nekushandura kudzokera kuchiratidzo chekutanga kana zviratidzo zvakasiyana, maitiro aya anovimbisa kugadzikana uye kururama kwechiratidzo, ukuwo achidzivirira kukuvara kwePLC uye kuderedza kukanganiswa kwezviratidzo panzvimbo paPLC, kunyanya masaini e clutter. Pamusoro pezvo, zviratidzi zvemagetsi zvinogonawo kuita shanduko yezviratidzo, zvakaita sekushandura masaini kubva kuPT10 connections kuita masaini e4-20mA uye kuaisa mumasisitimu ePLC, zvichidzivirira kusawirirana pakati pemagetsi nemagetsi uye kugadzirisa dambudziko rekupindirana pakati pezvisungo nemidziyo.

Mumashandisirwo chaiwo, akadai semuchina wekugadzira simbi, kuyerwa nekudzora kunoitwa kuburikidza nePLC, zvishandiso zve automation panzvimbo, uye ma actuator panzvimbo. Iyo PLC inoiswa mukabati yekudzora iri mazana emamita kubva panzvimbo (ichishanda patembiricha yemukamuri), uye zvishandiso zve automation kana ma thermocouples kubva panzvimbo inoburitsa masaini kuburikidza newaya kuenda kukabati yekudzora mukamuri yekudzora. Panguva ino, chiratidzo chinopinda muPLC chinofanira kuparadzaniswa uye chingadawo kushandurwa, senge kuparadzanisa 4-20mA uye kuchishandura kuita 0-5V usati wapinda muPLC. Midziyo inopedzisa kupatsanurwa uye kushandurwa kwezviratidzo zve thermocouple inonzi "thermocouple signal isolator" kana "thermocouple temperature transmitter". Basa rayo guru rinosanganisira kupatsanurwa kwechiratidzo chekupinda uye chiratidzo chekubuda, pamwe nekushandura chiratidzo che input mV level kubva ku thermocouple kuita zviratidzo zveindasitiri zvakajairwa (4-20mA, 0-5V, 0-10V).

Muchidimbu, kuisa masaini anoparadzanisa zvinhu zvakakosha zvikuru pakuvandudza kuvimbika kwemasisitimu emagetsi eindasitiri, kuderedza mwero wekukundikana, kuchengetedza michina yePLC, uye kuvandudza mhando yemasaini. Ndichimwe chezvinhu zvakakosha kuti ive nechokwadi chekuti masisitimu ekudzora anoshanda zvakanaka uye akavimbika.
