Sisitimu yekudzora maitiro ekutanga: Inopindura zviratidzo zvinobva kumidziyo yekushanda, ine chekuita nesystem, mamwe masisitimu anogona kurongwa, uye/kana mushandi, uye inogadzira sisitimu inoita kuti michina yekushanda nesystem ishande sezvinodiwa, asi haiite mabasa ekuchengetedza zvishandiso neSIL≥1 yakaziviswa. (Chidimbu: GB/T 21109.1-2007 (IEC 61511-1:2003, IDT) Kuchengetedzeka kunoshanda kwemasisitimu ane zvishandiso zvekuchengetedza muindasitiri yekushanda - Chikamu 1: Chimiro, tsananguro, sisitimu, hardware uye zvinodiwa zvesoftware 3.3.2)

Sisitimu Yekutanga Yekudzora Maitiro: Inopindura zviratidzo zvinobva mukuyera maitiro nezvimwe zvishandiso zvine chekuita nazvo, zvimwe zvishandiso, masisitimu ekudzora, kana maoperator. Zvinoenderana nemutemo wekutonga maitiro, algorithm uye nzira, chiratidzo chekubuda chinogadzirwa kuti chione kushanda kwekutonga maitiro uye zvishandiso zvine chekuita nawo. Muzvirimwa zve petrochemical kana zvirimwa, sisitimu yekutanga yekutonga maitiro inowanzo shandisa sisitimu yekudzora yakagoverwa (DCS). Masisitimu ekutanga ekutonga maitiro haafanire kuita mabasa ekuchengetedza eSIL1, SIL2, SIL3. (Chidimbu: GB/T 50770-2013 Kodhi yekugadzira masisitimu ekuchengetedza e petrochemical 2.1.19)

『SIS』

Sisitimu yemidziyo yekuchengetedza: Sisitimu yemidziyo inoshandiswa kuita basa rimwe chete kana akawanda ekuchengetedza michina. SIS inogona kuva nemusanganiswa we sensor, logic solver, uye final element.

Basa rekuchengetedza midziyo; SIF ine SIL chaiyo yekuita mabasa ekuchengetedza midziyo, ayo anogona kuva basa rekuchengetedza midziyo uye basa rekudzora kuchengetedzwa kwemidziyo.

Kuchengetedzwa kwekuchengetedza; SIL inoshandiswa kutsanangura mazinga akasiyana (rimwe remazinga mana) ezvinodiwa zvekuchengetedzwa kwekuchengetedza kwemabasa ekuchengetedza emidziyo akapihwa kumasisitimu emidziyo yekuchengetedza. SIL4 ndiyo nhanho yepamusoro yekuchengetedzwa kwekuchengetedza uye SIL1 ndiyo yakaderera.

Sisitimu yemidziyo yekuchengetedza: Sisitimu yemidziyo inoshandisa basa rimwe kana akawanda ane michina yekuchengetedza. (Chidimbu: GB/T 50770-2013 Kodhi yekugadzira masisitimu emidziyo yekuchengetedza petrochemical 2.1.1);

Musiyano uripo pakati peBPCS neSIS

Sisitimu yemidziyo yekuchengetedza (SIS) isina chekuita nehurongwa hwekudzora mashandiro BPCS (senge sisitimu yekudzora yakagoverwa DCS, nezvimwewo), kugadzirwa kunowanzo gara kwenguva refu kana kuti kusingachinji, kana mudziyo wekugadzira kana nzvimbo yacho ikakonzera tsaona dzekuchengetedza, inogona kuva chiito chakarurama ipapo ipapo, kuitira kuti maitiro ekugadzira amire kushanda zvakachengeteka kana kupinza otomatiki mamiriro ekuchengetedza akatarwa, anofanira kuva nekuvimbika kwakanyanya (ndiko kuti, kuchengetedzeka kunoshanda) uye manejimendi ekugadzirisa akajairwa, kana sisitimu yemidziyo yekuchengetedza ikakundikana, inowanzo tungamira kutsaona dzakakomba dzekuchengetedza. (Chidimbu: General Administration of Safety Supervision Nha. 3 (2014) Nha. 116, Maonero Ekutungamira eHurumende yeHurumende yeKutarisira Kuchengetedzeka paKusimbisa Kutungamirirwa kweMakemikari eZvishandiso zveKuchengetedza)

Zvinorehwa neSIS rusununguko kubva kuBPCS: Kana kushanda kwakajairika kweBPCS control loop kuchizadzisa zvinodiwa zvinotevera, kunogona kushandiswa sechikamu chekudzivirira chakazvimiririra, BPCS control loop inofanira kuparadzaniswa neSIF functional safety instrumented system (SIS), kusanganisira sensor, controller uye final element.

Musiyano uripo pakati peBPCS neSIS:

Mabasa akasiyana echinangwa: basa rekugadzira / basa rekuchengetedza;

Mamiriro akasiyana ekushanda: kutonga kwenguva chaiyo / kuvharira nguva yakawandisa;

Zvinodiwa zvakasiyana zvekuvimbika: SIS inoda kuvimbika kwakanyanya;

Nzira dzakasiyana dzekudzora: kudzora kunoenderera mberi sekutonga kukuru / kwepfungwa sekutonga kukuru;

Nzira dzakasiyana dzekushandisa nekugadzirisa: SIS yakaoma zvikuru;

Kubatana kweBPCS neSIS

Kana BPCS neSIS zvichigona kugovana zvikamu zvinogona kutariswa uye kutsanangurwa kubva pazvinhu zvitatu zvinotevera:

Zvinodiwa uye zvinopihwa zvezvinodiwa zvakajairwa, zvinodiwa zvekuchengetedza, nzira yeIPL, kuongororwa kweSIL;

Kuongororwa kwehupfumi (chero bedzi zvinodiwa zvekuchengetedza zvasangana), semuenzaniso, ongororo yeALARP (yakaderera sezvinobvira);

Vatungamiriri kana mainjiniya vanosarudzwa zvichibva pane zvakaitika uye kuda kwavo.

Chero zvazvingava, zvinodiwa zvishoma kuti zvienderane nezvinodiwa nemitemo nezvinodiwa zvinodiwa.
