PLC, DCS, FCS: AM - Kuyaka kwa mafakitale a mafakitale

M'malo a kuwongolera mafakitale, kumvetsetsa kusiyana ndi maubale pakati pa ma vcs, DCS, ndi FCss ndikofunikira. Nayi kuwonongeka mwatsatanetsatane:

Mwachidule za PLC, DCS, ndi FCS

• PLC (Wolamulira Wopanga):Kuyambira kuchokera ku njira zowongolera, ma plcs ndi zida zamagetsi zopangidwa kuti zizigwiritsa ntchito makina osinthika komanso osinthika. Amagwiritsa ntchito njira zothandizira kukumbukira malangizo, zomwe zimathandizira kuyendetsa makina osiyanasiyana ndi kupanga.

• DCS (dongosolo logawidwa):Kutuluka mu 1970 monga mamba opangira ndipo zowongolera zimawonjezeka, DCSS itanani malire a makina owongolera. Amakhala ndi maziko okhazikika ndi kuwongolera kwakukulu komanso kuwongolera pakati, kuphatikiza miliri - Technologies monga makompyuta, makompyuta, ndi kulankhulana.

• FCS (Progebus Controls):Njira yatsopano - yolamulira yoyendetsera masewera olimbitsa thupi mu 1990s, fcs imagwiritsa ntchito ukadaulo wam'munda kuti mulumikizane ndi zida za m'munda ndi owongolera, kupanga kulumikizana kwathunthu, komwe kumakwaniritsa digirimu yathunthu, yomwe imakwaniritsa bwino ntchito.

FCS ndi DCS kufanizira

Kukula: Ma FCs adachokera ku DCS ndi maluso a plc, kuphatikiza mawonekedwe awo akamayatsa kutembenuka. DCSS yamakono ndi ma plcs amasintha magwiridwe antchito, ndi DCSS yopeza mphamvu zowongolera mwamphamvu ndipo plcs imawongolera mutsekedwa - loop. Onsewa amatha kukhala ndi maukonde akuluakulu - oyambitsa maukonde, omwe amatsogolera kwambiri pakugwiritsa ntchito.

Zofunikira:

• Kulankhulana:Mu DCS, basi ya data imakhala ngati msana, ndi kapangidwe kake kamene kapangidwe kasinthasintha ndi chitetezo. Ogulitsa ambiri a DCS amapereka mabasi osafunikira ndipo amagwiritsa ntchito njira zovuta zolumikizirana ndi zolakwika - njira zopezera njira. Njira zoyankhulirana zimaphatikizapo njira zolumikizira komanso zokondweretsa.

• Kapangidwe:DCS nthawi zambiri imagwiritsa ntchito imodzi - kumodzi - kulumikizana kamodzi - kutumiza kolowera njira, pomwe fcs imagwiritsa ntchito imodzi - kugwirizanitsa ambiri ndi bi - kuphatikiza mitundu yowongolera - kuyika chizindikiro.

• Kudalirika:FCS ili ndi kudalirika bwino chifukwa cha digito siginecha ya digito yokhala ndi mphamvu yamphamvu - kusokonekera komanso kuwongolera kwambiri. Mosiyana ndi izi, DCS imagwiritsa ntchito ma andalog zizindikiro zomwe zimakonda kulowerera komanso kutsika pang'ono.

• Onetsetsani kuwongolera:FCS imakwaniritsa zonse zomwe zimapangitsa kuti zizigwirizana ndi zowongolera zomwe zimagwira ntchito ku zida za m'munda, pomwe DCS imangophatikizidwa pang'ono.

• Chida:FCS imagwiritsa ntchito kulumikizana kwanzeru ndi kulumikizana kwa digito ndikuwongolera, pomwe DC imadalira zida za Analog zocheperako.

• Njira zoyankhulirana:FCS imatengera digito yokwanira ya digito, yolumikizirana yowongolera yowongolera, pomwe DC ili ndi zomangamanga zosakanizidwa ndi kulumikizana kwa digito m'magawo apamwamba ndi ma andalog zizindikiro pamiyendo.

• Mgwirizano:FCS imalola kusokoneza kosavuta komanso kusokoneza zida kuchokera kwa ogulitsa osiyanasiyana pogwiritsa ntchito gawo lomwelo, pomwe DCS imavutika chifukwa cha njira yolumikizirana yolumikizirana.

PLC ndi DCS kufanizira

Plc:

• Zochita za Chisinthiko:PLCS yasintha kuchoka kuwongolera kuti ikhale yolamulira komanso kukonza deta, kenako ndikugwiritsa ntchito ma pid mosalekeza, ndi ma pid omwe ali m'malo osokoneza. Amatha kupanga maukonde a Plc ndi PC chimodzi ngati magwiridwe a Master ndi ma plc angapo monga malo a akapolo, kapena ndi mmodzi wa PLC ndi ena monga akapolo.

• Zolemba Zogwiritsira Ntchito:PLCS imagwiritsidwa ntchito potengera zowongolera mu mafakitale njira, ndipo ma pls amakono amagwiranso chotseka - lop.

DCS:

• Kuphatikiza:DCS imaphatikiza 4c (kulumikizana, kompyuta, kuwongolera, crt) matekiti owunikira ndi kuwongolera. Imakhala ndi mtengo - ngati utomoni wolankhulana ngati chinthu chofunikira.

• Zomanga Zamalonda:DCS ili ndi mawonekedwe atatu ophatikizika (Startional Station), opaleshoni (malo ogwiritsira ntchito), ndi zida zamunda (zida zamunda). Imagwiritsa ntchito ma andalog zizindikiro ndi A / D - D / kutembenuka ndi microprocesving ikuphatikizidwa. Chida chilichonse chimalumikizidwa kudzera pamzere wodzipereka ku i / o, zomwe zimalumikizidwa ndi LAN kudzera poyang'anira.

• Magawo ogwiritsira ntchito:DCS ndi yoyenera kwambiri - njira yopitilira njira, monga mu mafakitale a petrochemical.

Kuzindikira izi kumathandiza posankha ukadaulo woyenera wa magwiridwe antchito antchito antchito.
