Kungani i-PLC yenziwa isicaba kangaka?
2023-12-08
Ngokuncishiswa okuqhubekayo kwamanani e-PLC kanye nokwanda kwesidingo sabasebenzisi, imishini eminingi emincane nephakathi nendawo yaqala ukukhetha i-PLC yokulawula, ukusetshenziswa kwe-PLC e-China kukhula ngokushesha okukhulu. Ngokuthuthuka okusheshayo komnotho waseShayina kanye nokwenza ngcono okuqhubekayo kwezinga le-automation yasekhaya, i-PLC yaseShayina esikhathini esizayo isazoqhubeka nokuhambisana nomfutho wokukhula okusheshayo. Imikhiqizo yanamuhla ye-PLC ingahlukaniswa izikole ezintathu eziyinhloko: i-United States, i-Europe kanye nomlomo walokhu. Ngokuthuthuka okusheshayo kwe-PLC yaseChina, i-PLC yasekhaya ithatha isisindo esiningi. Ngokwezibalo, ngaphezu kwama-95% wezinga lokungaphumeleli kwale mikhiqizo ye-PLC avela kugesi, ukudluliselwa, imbobo yokuxhumana kulezi zindawo. Ngakho-ke indlela yokunciphisa izinga lokuhluleka kwalezi zindawo uGu Mei PLC enze lezi zinguquko. Ukunikezwa kwamandla ngaphandle ukuze kuqedwe ukwehluleka okungu-90%. Vimbela izinguquko zokushisa komoya, umswakama ushintsha ngaphansi kwethonya lomoya, uthuli, ukukhanya kwe-ultraviolet nezinye izici ukulimaza imishini. Okuvame kakhulu ukwehluleka ngokuvamile ohlelweni lokuphakelwa kwamandla kanye nesistimu yenethiwekhi yokuxhumana, ukunikezwa kwamandla kagesi emsebenzini oqhubekayo, ukuchithwa kokushisa, ukuguquguquka kwamandla kagesi kanye nokushintshashintsha kwamanje kumthelela akunakugwenywa. Ukuxhumana kanye nenethiwekhi ngokungenzeka kokuphazamiseka kwangaphandle, imvelo yangaphandle ingenye yezinto ezinkulu ezibangela ukwehluleka kwemishini yangaphandle yokuxhumana. Njengamanje, i-PLC emakethe iwumthombo wamandla owakhelwe ngaphakathi, kuyilapho imikhiqizo yethu isebenzisa amandla angaphandle ukuze iqede ukwehluleka okungama-90%. Idlulisela ngolunye lwemikhiqizo ehamba phambili - i-Omron Ukulawulwa kwezindleko zebhizinisi ze-PLC, ukukhethwa kuncike kumojula ye-I/O, I/O iyingxenye ebalulekile ye-PLC. isixhumanisi esikhulu esibuthakathaka se-PLC embobeni ye-I/O. inzuzo yobuchwepheshe ye-PLC yimbobo ye-I/O, esimweni sezinga lobuchwepheshe lesistimu yokusingatha umehluko phakathi kokungabikho komshini, imojula ye-I/O iyingxenye ebalulekile ebonisa ukusebenza kwe-PLC, ngakho futhi isixhumanisi esivelele emonakalweni we-PLC. I-relay esetshenziswa u-Gumei ngu-Omron, enye yezinhlobo eziyishumi ezihamba phambili emhlabeni. Ukuvikelwa okukhethekile kwembobo yokuxhumana Izinga lokudluliswa kwedatha yesixhumi esibonakalayo se-RS-232 liphansi, ibanga lokudlulisela lilinganiselwe, nekhono lokulwa nokuphazamiseka liphansi. I-RS-422 isebenzisa imodi yokuxhumana egcwele i-duplex enokudlulisa okuhlukile, futhi nekhono lokuphazanyiswa kwemodi ye-anticommon liyathuthukiswa. I-GuMei isebenzise imbobo engu-485, imbobo engama-485 kunembobo yama-voltage angu-232 iphezulu, akulula ukuyishisa. Ngalezi zindlela, izinga lokuhluleka kwe-PLC liyancipha kakhulu, futhi ivolumu ye-PLC ihlangene kakhulu kodwa isebenza kangcono, lezi zinhlelo zokusebenza ekhasimendeni zihlala zithola ukugunyazwa yikhasimende.
