Imiqondo eyisisekelo「BPCS」
Uhlelo Lokulawula Inqubo Okuyisisekelo: Iphendula ngokufaka amasiginali okufaka kwinqubo, imishini ehlobene nohlelo, ezinye izinhlelo ezinhlelweni, kanye / noma opharetha, futhi ikhiqiza uhlelo elenza inqubo kanye nemishini ehlobene nohlelo nge-sil≥1 esetshenzisiwe. (Excerpt: GB / T 21109.1-2007 (IEC 61511-1: 2003, IDT) Ukuphepha Okusebenzayo Kwezinhlelo Zokuphepha Embonini Yezokuphepha - Ingxenye 1: Izincazelo, Izidingo Zesoftware 3.3.2)
Uhlelo Lokulawula Inqubo Okuyisisekelo: Iphendula ukufaka amasiginali okufaka ezilinganisweni zenqubo neminye imishini ehlobene, ezinye izinsimbi, amasistimu wokulawula, noma ama-opharetha. NgokoMthetho Wokulawula Inqubo, i-algorithm nendlela, isinali yokuphuma senziwa ukuqaphela ukusebenza kokulawulwa kwenqubo kanye nemishini yayo ehlobene nayo. Ezitshalweni noma ezitshalweni ze-petrochemical, uhlelo oluyisisekelo lokulawula inqubo luvame ukusebenzisa uhlelo lokulawula olusatshalaliswa (i-DCS). Izinhlelo zenqubo eziyisisekelo zokulawula akufanele zenze imisebenzi enezinhlamvu zezokuphepha ku-Sil1, Sil2, Sil3.

「Sis」
Uhlelo lwe-Security Instrued System: Uhlelo olusetshenziselwe uhlelo lokusebenza lusetshenziselwa ukwenza imisebenzi eyodwa noma eminingana yensimbi. I-SIS ingahlanganisa noma yikuphi ukuhlanganiswa kwenzwa, i-solic solver, nento yokugcina.
Umsebenzi wokuphepha wensimbi; I-SIF inosili oluthile lokufeza imisebenzi yokuphepha ukuphepha kokuphepha, okungaba yimisebenzi yokuvikela ukuphepha kwensimbi kanye nomsebenzi wokulawula ukuphepha kwensimbi.
Izinga lobuqotho lokuphepha; I-SIL isetshenziselwa ukucacisa amazinga e-discrete (elinye lamazinga 4) ngezidingo zobuqotho zokuphepha zemisebenzi yezokuphepha enikezwe amasistimu ahlinzekiwe wokuphepha. I-Sil4 izinga eliphakeme kakhulu lokuphepha kokuphepha kanye ne-sil1 liphansi kakhulu.

Uhlelo lwe-Security Instrued System: uhlelo olufakiwe olusebenzisa imisebenzi eyodwa noma ngaphezulu yezokuphepha. .
Umehluko phakathi kwama-BPCs ne-SIS
Uhlelo lwe-Security Instrued System (SIS) oluzimele ngohlelo lwenqubo yokulawula uhlelo lwe-BPCs (efana ne-DCS yokulawula i-DCS, njll. yehluleka, kuvame ukuholela ezingozini ezinkulu zokuphepha. .
Okushiwo Ukuzimela kwe-SIS Ukuzimela kusuka kuma-BPCS: Uma ukusebenza okujwayelekile kwama-BPCS Lawula i-Loop kuhlangabezana nezidingo ezilandelayo, zingasetshenziswa njenge-loop ezimele yokuvikela, kufaka phakathi inzwa, kufaka phakathi inzwa, kubandakanya nento yokugcina.
Umehluko phakathi kwama-BPCs ne-SIS:
Imisebenzi yenhloso ehlukene: Umsebenzi wokukhiqiza / umsebenzi wokuphepha;
Isifundazwe esihlukile sokusebenza: Ukulawulwa kwesikhathi sangempela / isikhathi somkhawulo wesikhathi sokukhawulela;
Izidingo ezihlukile ezethenjwayo: I-SIS idinga ukuthembeka okuphezulu;
Izindlela ezahlukahlukene zokulawula: Ukulawulwa okuqhubekayo njengokulawula okuyinhloko / okunengqondo njengokulawula okuyinhloko;
Izindlela ezahlukahlukene zokusebenzisa nokulungiswa: I-SIS iqinile;
Ama-BPCs nokuxhumana kwe-SIS
Ukuthi ama-BPCs kanye ne-SIS angakwazi ukuhlanganyela futhi anqunywe kulezi zinto ezintathu ezilandelayo:
Izidingo nezinhlinzeko zokucaciswa okujwayelekile, izidingo zokuphepha, indlela ye-IPL, ukuhlolwa kwesilika;
Ukuhlolwa Kwezomnotho (kuhlinzekelwe ukuthi kuhlangatshezwane nezidingo zokuphepha eziyisisekelo), isib, i-alarp (njengephansi ngokunokwenzeka) ukuhlaziya;
Abaphathi noma onjiniyela banqunywa ngokususelwa kokuhlangenwe nakho kanye nentando yentando ye.
Noma iyiphi indlela, imfuneko ephansi yokuhlangabezana nezidingo zemithethonqubo iyadingeka.
