A PLC mhando yekomputa inoshanda mune mamwe maindasitiri nharaunda, kana iwe uchifarira kuziva mashandiro ayo uye ndeapi Mhando dzePLC inodhura kupfuura iwe yaunogona kuwana mavari, saka ive shuwa kuti uverenge chinyorwa chedu umo isu tichakupa iwe rwese rwakakosha ruzivo.
Mhando dzePLC
PLC inomirira Programmable Logic Controller, komputa inoshanda munzvimbo dzine njodzi zvakanyanya kana tekinoroji kuti ishande sechibatanidziro mune akasiyana maindasitiri maitiro. Izvi zvinhu zviripo pamusika zvinotevera.
- Modular.
- Compact
- Rack gomo.
- Ndiine opareta pani.
- Industrial komputa.
- Groove.
- Rudzi rweSoftware.
- Narrow band.
- Yakadzika bhendi.
Dzinowanzo dhinomineta mavari ndedze kushanda sekutonga kweanoteedzerana relay, kudzora kufamba, mafambiro, iyo yakagovaniswa control system uye kutaurirana mune network. Iko kugona kwePLC kushandisa, kuchengetedza, kuita uye kutaurirana kunozadzisa zvakaenzana mabasa ekombuta desktop. Ziva zvakare kuti chii chinonzi Vanogadzira Nhoroondo mune Basic Computer Science.
Yakadaro otomatiki komputa ine mukana wekugamuchira maseru ekuisa pamwe neakanangana nekubuda kwakateerana. Dzakatanga kushandiswa muma1960 seimwe nzira yekushandisa zvekare masisitimu ekudzosera kumashure, vaishandisa mutauro wekuraira uye mushure mekuratidzira graphical inonzi Manera kana manera mutauro.
Parizvino, maPLC haangogadzirise kutonga kweanoshanda mashini, michina uye maindasitiri maitiro, asi anoshandiswawo mune arithmetic mashandiro mashandiro, kubata kwemaanalog masaini ekugadzira akasiyana maitiro ekudzora akadai sePID (Proportional, Integral uye Derivative ).
Hunhu hwemhando dzePLC
Kuve chinhu chinobatsira kwazvo mukushandisa kwakasiyana siyana, chakakwanisa kuchengetedza kuramba kwayo kushandisa muzvikamu zvakasiyana zveiyi indasitiri, kutora kutonga kwese kunoenderana maitiro uye neshanduko dzinogona kugadzirwa munzvimbo kana michina yekuita inoda kuongororwa kwepakati nepurogiramu. . Hunhu hwayo hukuru hunotevera:
- Vakaverenga masaini kubva kuma sensors akaparadzirwa.
- Ivo vanogadzira kutaurirana nezvikwata zvese munguva chaiyo.
- Inopindirana iyo inobvumidza kushandiswa uye nhaurirano yevanoshanda.
- Kubatana kunogona kuitwa kune yekutarisa system iyo inoita kuti interface ishande uye kugadzirisa maitiro kuve nyore.
- Iine kugona kuzvigadzirisazve mumhando dzakasiyana dzemitauro.
- Ivo vanogona kugamuchira uye nekuita odhita zvinowirirana nekufamba kwenguva.
- Ivo vanodzora zvinopinda uye zvinobuda izvo zvinogoverwa uye izvo zviri kunze kwepakati automaton kabhini kuburikidza netambo yedandemutande.
Nhoroondo yePLCs
Pakupera kwema1960, maindasitiri aitsvaga nzira yekuwana hunyanzvi hwemagetsi hutsva hwaizopa mhinduro dziri nani kuti akwanise kutsiva masystem ekudzora ayo aive akavakirwa pamaseketi emagetsi aine ma relays, switch uye zvimwe zvinhu zvaishandiswa. muCombinational Logic control masisitimu. Imwe nyaya iwe yaunofanirwa kuziva ndeyekuti chii chakakosha Plastiki Optical Fiber.
Pakazosvika 1968 General General Motors Hydramatic, chikamu chakabata otomatiki kutapurirana mukambani, chakakumbira zvikumbiro zvekushandurwa kwemagetsi eiyo relay waya masisitimu. Bedford Associates ndiye akahwina chirongwa ichi uye aive achitungamira kugadzira kambani yakazvipira mukusimudzira, kugadzira, kutengesa uye kugadzirisa zvigadzirwa zvitsva: iyo Modicon (Modular Dhijitari Controler).
Dick Morley aive mumwe wevanhu vakashanda pachirongwa ichi chitsva uye anofungidzirwa kuti ndiye akagadzira maPLCs, chigadzirwa cheModicon chakatengeswa kusvika 1977 kuna Gould Electronics iyo yakazowanikwa neAEG, kambani yekuGerman iyo makore akazotevera Yakatengeswa ku kambani yeFrance Schneider Electric Global, iyo parizvino ine zvigadzirwa.
Kubatsira uye Kukanganisa kwemhando dzePLC
Kubatsira kukuru kwemuchina uyu kuchengetedza nguva kana uchigadzirira mapurojekiti akasiyana siyana, pamwe nekutendera kuti kugadziriswe kuitwe pasina imwezve mari. MaPLC madiki muhukuru uye haadhure, kuchengetedza mari yevashandi uye nekupa kugona kuchengetedza kutonga kweakawanda michina kuburikidza nemidziyo yakafanana.
Midziyo iyi inokwanisa kumira mukugunun'una kunogadzirwa nemamashini, uye kuti chero chinhu chingave chisina kusimba zvekuti chaisazogara kwenguva refu mavari nekuti vanokundikana kana kutyoka. Iwe haufanire kupotsa kuziva izvo iyo Technology Njodzi.
Sezvazviri mune chero chinhu chemagetsi, chikuru chekukanganisa kwavo ndechekuti ivo vanoda basa revanyanzvi vanonyatsokwanisa mavari kuti vatarisire mashandiro aro akanaka uye nekuchengetedza kwadzo.
