Izingxenye Zemvelo ye-ICS

Imvelo yesistimu yokulawula izimboni (i-ICS) iqukethe izingxenye ezimbalwa ezibalulekile ezisebenza ndawonye ukuze zizenzele futhi zilawule izinqubo zezimboni kahle. Lezi zingxenye zihlanganisa:

Amayunithi Esiteshi Esikude (ama-RTU) : Ama-RTU amadivayisi asensimini ahlonyiswe ngama-microprocessor aqoqa idatha kusuka kuzinzwa nemishini ezindaweni ezikude. Asebenza njengesixhumanisi phakathi komhlaba obonakalayo kanye nohlelo lokulawula. Ama-RTU aqoqa ulwazi, alucubungule, futhi aludlulisele ohlelweni lokulawula oluphakathi ukuze luhlaziywe futhi lwenziwe izinqumo.

Ama-Control Loops : Ama-control loops ayisisekelo se-ICS futhi ahilela izinzwa, abalawuli, kanye nama-actuator. Ahlala eqapha futhi elawula izinqubo ukuze alondoloze izimo ezifiselekayo. Izinzwa zilinganisa amapharamitha afana nokushisa, ingcindezi, kanye nokugeleza, kuyilapho abalawuli belungisa ama-actuator (isb., ama-valve, ama-motor) ukuze alondoloze izindawo ezibekiwe. Ama-control loops adlala indima ebalulekile ekufezeni ukulawula okunembile phezu kwezinqubo zezimboni.

I-Human-Machine Interface (HMI) : I-HMI iyi-interface yomsebenzisi enezithombe evumela opharetha abangabantu ukuthi basebenzisane futhi baqaphe uhlelo lokulawula lwezimboni. Ihlinzeka ngokubona idatha ngesikhathi sangempela, amakhono okulawula, kanye nama-alamu. Opharetha basebenzisa ama-HMI ukuqondisa izinqubo, ukwenza izinqumo, nokuphendula ezimeni ezingavamile noma ama-alamu. I-HMI eklanywe kahle ithuthukisa ukuqwashisa ngesimo kanye nokusebenza kahle kopharetha.

Iseva Yokulawula : Iseva yokulawula iyisici esiyinhloko se-ICS esinomthwalo wokucubungula idatha, ukusebenzisa ama-algorithm okulawula, kanye nokuxhumanisa ukusebenza kwesistimu yonke. Ithola idatha evela kuma-RTU, iyicubungule, futhi ithumele imiyalo yokulawula kuma-actuator. Ukuthembeka nokusebenza kweseva yokulawula kubalulekile ekuzinzeni kwesistimu iyonke.

Iyunithi Yesiphetho Esiyinhloko (i-MTU) : I-MTU isebenza njengomlawuli oyinhloko ngaphakathi kwe-ICS, iqondisa izihibe zokulawula ezahlukahlukene futhi iqondisa izenzo zazo. Iphatha ukuxhumana phakathi kweseva yokulawula namadivayisi asensimini, iqinisekisa ukuthi idatha idluliselwa ngokunembile nangesikhathi. I-MTU idlala indima ebalulekile ekugcineni ubuqotho besistimu kanye nokuphendula.

Amadivayisi E-elekthronikhi Ahlakaniphile (ama-IED) : Ama-IED amadivayisi ahlakaniphile aqoqa idatha, ashintshana ngolwazi namanye amadivayisi, futhi enze ukulawula nokucubungula kwendawo. Abalulekile ekusebenziseni imisebenzi ethuthukisiwe ngaphakathi kwe-ICS. Ama-IED angafaka phakathi ukudluliselwa kokuvikela, abalawuli be-logic abahlelekayo (ama-PLC), kanye namanye amadivayisi akhethekile aklanyelwe izinhlelo zokusebenza ezithile zezimboni.

Isazi-mlando Sedatha : Isazi-mlando sedatha siyisizindalwazi esihlanganisiwe esiqopha futhi sigcine idatha yomlando evela ezingxenyeni ezahlukene ze-ICS. Sibamba ulwazi lwenqubo, ukufundwa kwezinzwa, izenzo zokulawula, kanye nemicimbi ngokuhamba kwesikhathi. Izazi-mlando zedatha zibaluleke kakhulu ekuhlaziyweni kwemikhuba, ukwenza ngcono ukusebenza, ukuhambisana nemithetho, kanye nokuxazulula izinkinga.

Lezi zingxenye zisebenza ngokuvumelana ukuze kuqinisekiswe ukusebenza kahle nokuthembekile kwezinhlelo zokulawula izimboni kuzo zonke izimboni ezihlukahlukene. Anika amandla ukuqapha okunembayo, ukulawula, kanye nokuzenzakalela kwezinqubo ezibalulekile, kukhuphula ukukhiqiza, ukuphepha, nokusetshenziswa kwezinsiza.

Ukuxhumana ngaphakathi kwe-Industrial Control Systems

I-Industrial Control Systems (ICS) isebenzisa isethi ehlukahlukene yezivumelwano zokuxhumana ukuze zinike amandla ukushintshaniswa nokulawula idatha. Lezi zivumelwano zihlanganisa i-Ethernet ye-Control Automaton Technology (EtherCAT), Common Industrial Protocols (CIP), Open Platform Communication (OPC), Modbus, Distributed Network Protocol (DNP), kanye ne-Process Field Bus (PROFIBUS), edlala indima ebalulekile ekusizeni ukusebenza kahle. ukuxhumana nokulawula ukusebenza ngaphakathi kohlelo.
