Vim li cas PLC thiaj li tiaj tus?
2023-12-08 IB
Nrog kev txo qis ntawm PLC cov nqi thiab kev nthuav dav ntawm cov neeg siv khoom xav tau, ntau thiab ntau cov khoom siv me me thiab nruab nrab pib xaiv PLC rau kev tswj, daim ntawv thov ntawm PLC hauv Suav teb tau loj hlob sai heev. Nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj txoj kev lag luam thiab kev txhim kho txuas ntxiv ntawm qib ntawm kev siv hluav taws xob hauv tsev, PLC hauv Suav teb nyob rau lub sijhawm tom ntej yuav tseem ua raws li lub zog ntawm kev loj hlob sai. Niaj hnub no cov khoom PLC tuaj yeem muab faib ua peb lub tsev kawm ntawv tseem ceeb: Tebchaws Asmeskas, Tebchaws Europe thiab lub qhov ncauj ntawm qhov no. Nrog rau txoj kev loj hlob sai ntawm Tuam Tshoj PLC, lub PLC domestic PLC tuav ntau thiab ntau qhov hnyav. Raws li kev txheeb cais, ntau dua 95% ntawm qhov tsis ua haujlwm ntawm cov khoom PLC no tshwm sim hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, kev sib txuas lus chaw nres nkoj ntawm cov chaw no. Yog li yuav ua li cas txo qis qhov tsis ua haujlwm ntawm cov chaw no Gu Mei PLC ua cov kev hloov pauv no. Fais fab mov sab nraud kom tshem tawm 90% ntawm qhov ua tsis tiav Tiv thaiv huab cua hloov pauv, av noo hloov pauv raws li huab cua, plua plav, lub teeb ultraviolet thiab lwm yam ua rau cov khoom puas. Qhov feem ntau ua rau tsis ua hauj lwm feem ntau nyob rau hauv cov khoom siv hluav taws xob thiab kev sib txuas lus sib txuas lus, cov khoom siv hluav taws xob hauv kev ua haujlwm tas mus li, cua sov dissipation, voltage thiab tam sim no hloov pauv hauv qhov cuam tshuam yog inevitable. Kev sib txuas lus thiab kev sib txuas lus los ntawm qhov muaj peev xwm ntawm kev cuam tshuam sab nraud, ib puag ncig sab nraud yog ib qho tseem ceeb tshaj plaws uas ua rau tsis muaj kev sib txuas lus nrog cov khoom siv sab nraud. Tam sim no, PLC nyob rau hauv kev ua lag luam yog ib qho kev siv hluav taws xob tsim-hauv, thaum peb cov khoom siv hluav taws xob sab nraud kom tshem tawm 90% ntawm qhov ua tsis tiav. Relays nrog ib lub npe zoo tshaj plaws - Omron Kev tswj hwm tus nqi ntawm PLC, kev xaiv yog nyob ntawm I / O, I / O module yog ib qho tseem ceeb ntawm PLC. PLC qhov txuas tsis muaj zog tshaj plaws hauv I / O chaw nres nkoj. qhov zoo dua ntawm PLC yog nws qhov chaw nres nkoj I / O, nyob rau hauv rooj plaub ntawm tus tswv system cov txheej txheem ntawm qhov sib txawv ntawm tsis muaj tshuab, I / O module yog qhov tseem ceeb ntawm kev ua haujlwm ntawm PLC, yog li nws kuj yog ib qho txuas tseem ceeb hauv PLC kev puas tsuaj. Lub relay siv los ntawm Gumei yog Omron, yog ib lub ntiaj teb sab saum toj kaum hom. Kev sib txuas lus chaw nres nkoj tshwj xeeb tiv thaiv RS-232 interface cov ntaub ntawv xa tawm tus nqi qis, qhov kev sib kis tau raug txwv, thiab muaj peev xwm tiv thaiv kev cuam tshuam tsis zoo. RS-422 txais kev sib txuas lus puv-duplex nrog kev sib kis sib txawv, thiab kev cuam tshuam hom kev cuam tshuam muaj peev xwm txhim kho. GuMei siv 485 chaw nres nkoj, 485 chaw nres nkoj tshaj 232 chaw nres nkoj voltage kuj yog siab, tsis yooj yim rau hlawv tawm. Los ntawm cov txheej txheem no, qhov ua tsis tiav ntawm PLC tau txo qis heev, thiab PLC ntim ntau dua tab sis kev ua tau zoo dua, cov ntawv thov no hauv cov neeg siv khoom ib txwm tau txais kev pom zoo ntawm cov neeg siv khoom.
