Mfundo zoyambira『BPCS』

Dongosolo loyang'anira njira zoyambira: Limayankha zizindikiro zolowera kuchokera ku njira, zida zokhudzana ndi makina, machitidwe ena okonzedwa, ndi/kapena wogwiritsa ntchito, ndikupanga dongosolo lomwe limapangitsa njira ndi zida zokhudzana ndi makina kugwira ntchito momwe zimafunikira, koma silichita ntchito zilizonse zachitetezo cha zida ndi SIL yolengezedwa≥1. (Chidule: GB/T 21109.1-2007 (IEC 61511-1:2003, IDT) Chitetezo chogwira ntchito cha makina otetezedwa mumakampani opanga makina - Gawo 1: Chimango, matanthauzidwe, zofunikira za makina, zida ndi mapulogalamu 3.3.2)

Dongosolo Loyang'anira Njira Yoyambira: Limayankha zizindikiro zolowera kuchokera ku miyeso ya njira ndi zida zina zokhudzana nazo, zida zina, machitidwe owongolera, kapena ogwiritsa ntchito. Malinga ndi lamulo loyang'anira njira, njira ndi njira, chizindikiro chotulutsa chimapangidwa kuti chigwire ntchito yoyang'anira njira ndi zida zake zokhudzana nazo. Mu zomera za petrochemical kapena zomera, dongosolo loyang'anira njira yoyambira nthawi zambiri limagwiritsa ntchito njira yowongolera yogawidwa (DCS). Machitidwe owongolera njira yoyambira sayenera kuchita ntchito zotetezedwa za SIL1, SIL2, SIL3. (Chidule: GB/T 50770-2013 Code yopangira makina oteteza petrochemical 2.1.19)

『SIS』

Dongosolo la zida zodzitetezera: Dongosolo la zida zodzitetezera lomwe limagwiritsidwa ntchito kukhazikitsa ntchito imodzi kapena zingapo zachitetezo cha zida. SIS ikhoza kukhala ndi kuphatikiza kulikonse kwa sensa, yankho la logic, ndi chinthu chomaliza.

Ntchito yoteteza zida; SIF ili ndi SIL yeniyeni kuti ikwaniritse ntchito zoteteza chitetezo, zomwe zingakhale ntchito yoteteza chitetezo cha zida komanso ntchito yowongolera chitetezo cha zida.

Mulingo wa umphumphu wa chitetezo; SIL imagwiritsidwa ntchito kutchula milingo yosiyana (imodzi mwa milingo 4) ya zofunikira pa umphumphu wa chitetezo cha zida zomwe zimaperekedwa ku makina otetezedwa. SIL4 ndiye mulingo wapamwamba kwambiri wa umphumphu wa chitetezo ndipo SIL1 ndiye wotsika kwambiri.
(Chidule: GB/T 21109.1-2007 (IEC 61511-1:2003, IDT) Chitetezo chogwira ntchito cha makina otetezedwa a makampani opanga zinthu Gawo 1: Chimango, matanthauzo, zofunikira pamakina, zida ndi mapulogalamu 3.2.72/3.2.71/3.2.74)

Dongosolo la zida zodzitetezera: Dongosolo la zida zomwe zimayendetsa ntchito imodzi kapena zingapo za zida zodzitetezera. (Chidule: GB/T 50770-2013 Khodi yopangira makina a zida zodzitetezera za petrochemical 2.1.1);

Kusiyana pakati pa BPCS ndi SIS

Dongosolo la zida zodzitetezera (SIS) lopanda dongosolo lowongolera njira BPCS (monga dongosolo lowongolera logawidwa DCS, ndi zina zotero), kupanga nthawi zambiri kumakhala kopanda kanthu kapena kosakhazikika, chipangizo chopangira kapena malo opangira zinthu chikangoyambitsa ngozi zachitetezo, chingakhale chochitapo kanthu nthawi yomweyo, kotero kuti njira yopangira zinthu isiye kugwira ntchito bwino kapena kulowetsa yokha boma lodzitetezera lokhazikika, liyenera kukhala lodalirika kwambiri (ndiko kuti, chitetezo chogwira ntchito) komanso kasamalidwe kokhazikika kosamalira, ngati dongosolo la zida zodzitetezera lalephera, nthawi zambiri limayambitsa ngozi zazikulu zachitetezo. (Chidule: General Administration of Safety Supervision No. 3 (2014) No. 116, Malingaliro Otsogolera a Boma la Administration of Safety Supervision pa Kulimbitsa Kasamalidwe ka Mankhwala Oteteza Zida)

Tanthauzo la kudziyimira pawokha kwa SIS kuchokera ku BPCS: Ngati ntchito yachizolowezi ya BPCS control loop ikukwaniritsa zofunikira izi, ingagwiritsidwe ntchito ngati gawo lodziyimira pawokha loteteza, BPCS control loop iyenera kulekanitsidwa ndi SIF yogwira ntchito yoteteza zida zachitetezo (SIS), kuphatikiza sensa, chowongolera ndi chinthu chomaliza.

Kusiyana pakati pa BPCS ndi SIS:

Ntchito zosiyanasiyana: ntchito yopanga / ntchito yoteteza;

Mikhalidwe yosiyana yogwirira ntchito: kuwongolera nthawi yeniyeni / kutsekereza nthawi yochulukirapo;

Zofunikira zosiyanasiyana zodalirika: SIS imafuna kudalirika kwakukulu;

Njira zosiyanasiyana zowongolera: kulamulira kosalekeza monga kulamulira kwakukulu / kwanzeru monga kulamulira kwakukulu;

Njira zosiyanasiyana zogwiritsira ntchito ndi kukonza: SIS ndi yovuta kwambiri;

Kulumikizana kwa BPCS ndi SIS

Ngati BPCS ndi SIS zingagawane zigawo zitha kuganiziridwa ndikutsimikiziridwa kuchokera kuzinthu zitatu izi:

Zofunikira ndi malangizo a muyezo, zofunikira za chitetezo, njira ya IPL, kuwunika kwa SIL;

Kuwunika zachuma (bola ngati zofunikira zoyambira zachitetezo zakwaniritsidwa), mwachitsanzo, kusanthula kwa ALARP (kotsika momwe kungatheke);

Oyang'anira kapena mainjiniya amatsimikiziridwa kutengera zomwe akumana nazo komanso chifuniro chawo.

Mulimonsemo, chofunikira chochepa kuti mukwaniritse zofunikira za malamulo ndi miyezo ndichofunika.
