A: Iyunithi yokulawula eyinhloko iyisilawuli se-programmable logic (PLC), esibophezelekile ukuthola amasiginali okokufaka, ukwenza uhlelo lokucabanga, kanye nemiyalo yokulawula okukhiphayo. Lenza imisebenzi enengqondo, isikhathi, ukubala, nokunye ukucutshungulwa ngokohlelo olusethiwe.
IMP: Yebo, ukuqapha isimo esikude,{0}}ukusebenza kwesikhathi sangempela, nokuphathwa kwedatha kungafinyelelwa ngamamojula e-Ethernet, amamojula e-4G/5G, noma izinkundla ze-IoT.
3.Iziphi izakhi zokuzivikela ezivame ukusetshenziswa kukhabhinethi yokulawula ye-PLC?
A: Izingxenye zokuzivikela ezivame ukusetshenziswa zihlanganisa ukushintsha komoya, izinsimbi zamanje ezisele (ama-RCD), ama-fuse, nama-thermal relays, asetshenziselwa ukulayisha ngokweqile, isifunda esifushane, ukuvuza kwamanje, nokuvikelwa kwe-overcurrent, ngokulandelana.Umsebenzi wawo oyinhloko uwukuqinisekisa ukuphepha kwemishini, imigqa, kanye nabasebenzi.
I: Amasiginali okokufaka aphuma kakhulu kumadivayisi okutholayo njengezinzwa, izinkinobho, ukushintsha okukhawulelwe, namaswishi ekusondela. Asetshenziselwa ukuqoqa isimo semishini, ukucubungula idatha, neziyalezo zokusebenza mathupha.
A:Izinzuzo zayo eziyinhloko wukuvumelana nezimo okuphezulu (uhlelo lungalungiswa ngaphandle kokushintsha izintambo zehadiwe), ukwethembeka okuphezulu, isivinini sokuphendula esisheshayo, kanye nokulula kokugcinwa nokuthuthukiswa. Okubalulekile, iwukuthuthuka ukusuka "{1}}kungqondongqondo{1}}okunezintambo" kuya "kukulawula okuhlelekayo".
A:Yebo, kungenziwa ngokusebenzisa i-interface ye-I/O esezingeni, amamojula e-analog, noma izimiso zebhasi. Ingashintshwa ibe ama-activator avela kumikhiqizo ehlukene njengamamotho, amasilinda, namavalvu e-solenoid, futhi ingafinyelela ukuxhumana ngokusebenzisa ukuxhumana okujwayelekile noma izivumelwano.
A: Nakanjani. Ama-PLC kanye nezingxenye ze-elekthronikhi zizwela izinga lokushisa. Ukushisa okungalungile kungaholela emaphutheni ezinhlelo kanye nokulimala kwengxenye, okuthinta ngokuqondile isikhathi sokuphila sezingxenye eziyinhloko, ukunemba kokulawula, nokuzinza kwesistimu.Ukushisa okuphezulu kungenye yezimbangela eziyinhloko zokuhluleka kwemishini, futhi abalandeli noma ama-air conditioner ngokuvamile ayadingeka ukuze kukhishwe ukushisa.
Isetshenziswa ezimeni zezimboni ezidinga ukulawula okuzenzakalelayo, njengokuzenzakalela komugqa wokukhiqiza, ukulawulwa kwamathuluzi omshini, ukuphatha izinto ezibonakalayo, okokuvikela imvelo (njengokuhlanza indle), kanye nemishini emisha yamandla, ehlanganisa izixhumanisi zokukhiqiza eziyinhloko zezimboni eziningi.
IMP: Yebo, ziyadingeka, kodwa lezi zilimi zisezingeni lomhlaba wonke futhi azikhethekile kunoma yiluphi uhlobo oluthile. Zisekelwe kuzinga le-IEC 61131-3 (izinga elijwayelekile lokuhlela lezinto ezishintshayo zezimboni), zinejika lokufunda elilingene, futhi zijwayelane nezimo zokulawula ezahlukahlukene.
A: Ukugcinwa njalo kuyadingeka. Amaphuzu abalulekile ukuhlanza uthuli, ukuhlola amatheminali ezintambo ezixegayo, ukusekela izinhlelo ze-PLC, nokuhlola ukusebenza kwezingxenye zokuzivikela. Ukunakekelwa okuvamile kungavimbela ukwehluleka okubangelwa izici zemvelo, ukuguga kwengxenye, njll., kuqinisekise{3}}ukusebenza okuzinzile kwesistimu isikhathi eside, futhi kwandise impilo yesevisi yezisetshenziswa.
Uma ufuna ukwazi okwengeziwe ngamayunithi esishintshisi sokushisa noma unentshisekelo yokuthenga, sicela uthumele i-imeyili ku-9988xiaoshuai@gmail.com, sizokuphendula ngokuhamba kwesikhathi ngemva kokubona umlayezo!
Ithimba lochwepheshe
Inkampani yethu ihlome ngekhwalithi ephezulu-ngemva{1}}yethimba lesevisi yokuthengisa elinezisebenzi zezobuchwepheshe njengomgogodla, futhi izonikeza impendulo ngesikhathi lapho ithola izaziso zolwazi lwesevisi kubasebenzisi.
7x24 amahora ukulethwa
Inkampani yethu inikeza ukwesekwa kwamahhala kwezobuchwepheshe kwemikhiqizo esiyithengisayo futhi ihlela ukuqeqeshwa kobuchwepheshe kwabasebenzi abafanelekile.
