Kev piav qhia txog kev paub yooj yim ntawm PLC tswj txee
May 02, 2026
PLC-Based Control Txee yog tag nrho cov khoom siv hluav taws xob tswj, feem ntau yog siv los paub txog kev tswj tsis siv neeg lub cev muaj zog, hloov pauv thiab lwm yam actuators. Raws li ib feem tseem ceeb ntawm kev lag luam automation system, Automation Vaj Huam Sib Luag txee muaj ntau yam kev tiv thaiv xws li overload, luv Circuit Court thiab theem poob. Nws muaj cov qauv compact, ruaj khov, thiab kev ua haujlwm zoo. Raws li qhov tseeb tswj qhov ntsuas, Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob tuaj yeem ua ke ua ke kom ua tiav kev tswj hwm ywj pheej ntawm ib lub txee, lossis tsim kom muaj kev tswj hwm kev faib tawm (DSC) los ntawm kev lag luam Ethernet lossis fieldbus tes hauj lwm, yog li hloov mus rau kev lag luam automation daim ntawv thov scenarios ntawm cov nplai sib txawv, thiab tau dav siv hauv hluav taws xob, metallurgy, tshuaj tiv thaiv kev lag luam, kev kho dej, thiab lwm yam.

Cheebtsam thiab cov qauv yooj yim
Huab cua hloov: Raws li lub zog tseem ceeb tswj cov khoom hauv lub txee. PLC: Xaiv raws li engineering xav tau. Cov haujlwm me me tuaj yeem siv cov khoom sib xyaw ua ke Dustproof PLC (Compact PLC Txee); Cov phiaj xwm loj tuaj yeem siv cov qauv siv los yog rov ua dua PLC kom ntseeg tau siab . 24V DC fais fab mov: Feem ntau PLCs tuaj nrog 24V DC fais fab mov, tab sis yog tias muaj cov khoom loj lossis cov khoom siv hluav taws xob cais, yuav tsum muaj kev hloov hluav taws xob ntxiv. Relay: Thaum lub PLC tso zis yog 24V DC thiab lub voj tswj yuav tsum muaj 220V AC node, yuav tsum muaj relay rau qib hloov dua siab tshiab thiab kev sib cais. Terminal blocks: configured raws li tus naj npawb ntawm cov teeb liab, yog cov ntsiab lus tseem ceeb ntawm kev xaim hauv lub txee. Tsis tas li ntawd, cov keyboards, cov kab hluav taws xob ntxiv thiab lwm yam khoom siv tuaj yeem raug ntxiv raws li ntawm -qhov chaw xav tau rau cov cuab yeej siv hluav taws xob lossis kev sib txuas lus nrog lub tshuab computer.
Fais fab mov: Lub tshuab hluav taws xob txhim khu kev qha yog lub hauv paus rau kev ua haujlwm ntawm PLC. Thaum qhov kev hloov pauv ntawm AC voltage nyob rau hauv thaj tsam ntawm +10% ~ +15%, nws tuaj yeem txuas ncaj qha mus rau daim phiaj hluav taws xob. Central processing unit (CPU): Lub chaw tswj hwm ntawm PLC, lub luag haujlwm rau kev txais thiab khaws cia cov neeg siv cov kev pab cuam, kuaj xyuas qhov xwm txheej ntawm lub cev, thiab ua haujlwm kev ua lej thiab lej. Hauv cov tshuab loj, dual-CPU redundancy lossis peb-CPU cov txheej txheem pov npav tuaj yeem siv los txhim kho kev ntseeg tau. Nco: Lub kaw lus kaw lus software hu ua system program memory, thiab khaws cia daim ntawv thov software hu ua neeg siv qhov kev nco. Input thiab output interface circuits: Interfaces nrog rau ntawm - site input signals los ntawm optical coupling circuits thiab outputs tswj cov teeb liab rau cov khoom ua. Muaj nuj nqi modules: tshwj xeeb modules xws li siab- suav ceev, kev tswj qhov chaw, thiab lwm yam. Kev sib txuas lus module: txhawb nqa cov ntaub ntawv sib pauv nrog lub computer tswj, lwm yam controllers los yog teb li.

Txoj cai ua haujlwm
Cov txheej txheem khiav PLC tau muab faib ua peb theem: kev coj ua piv txwv, cov neeg siv kev ua tiav, thiab cov khoom tso tawm tshiab. Peb theem no yog ib lub voj voog scan. Input sampling theem: nyeem tag nrho cov input xwm txheej nyob rau hauv ib theem zuj zus thiab khaws cia rau hauv I/O duab cheeb tsam. Tom qab theem no, txawm tias cov kev hloov pauv sab nraud, cov duab hauv cheeb tsam cov ntaub ntawv yuav tsis hloov. Tus neeg siv qhov kev ua tiav theem: Luam theej duab cov neeg siv cov kev pab cuam (xws li daim duab ntaiv) los ntawm sab saum toj mus rau hauv qab thiab los ntawm sab laug mus rau sab xis, ua haujlwm zoo, thiab rov kho cov xwm txheej ntawm cov kauj sib txuas lossis cov zis hauv RAM lossis I / O duab cheeb tsam. Output refresh theem: CPU refreshes tag nrho cov tso zis latch circuits raws li cov xwm txheej ntawm I / O duab cheeb tsam, tsav cov khoom siv sab nraud, thiab ua tiav cov zis tawm.

Tej thaj chaw thov
Standard PLC Txee tuaj yeem ua tiav cov khoom siv -theem automation thiab txheej txheem- theem automation tswj, thiab muaj cov yam ntxwv ntawm kev sib txuas lus hauv network muaj peev xwm, kev ua haujlwm tau zoo, thiab kev tiv thaiv zoo tshaj - cuam tshuam kev ua haujlwm. Cov ntawv thov muaj xws li cov dej tsis tu ncua, kev tswj cua compressor, kiv cua thiab twj tso kua mis tswj, nruab nrab cua txias tshuab, chaw nres nkoj machinery, tshuab cuab yeej, boilers, ntawv machinery thiab khoom noj khoom haus, thiab lwm yam. Modular PLC txee kuj flexibly configure I/O modules raws li cov txheej txheem kev hloov mus rau lub adaptability system.

tiv tauj peb
Peb tsom mus rau R & D thiab kev tsim khoom ntawmPLC tswj txee, muab cov khoom nyob rau hauv ntau yam khoom thiab specifications, los ntawm hlau hluav taws xob txee, stainless hlau hluav taws xob txee rau GRP hluav taws xob txee. Peb tau cog lus los muab cov neeg siv khoom txhim khu kev qha thiab kev tshaj lij hluav taws xob txee daws teeb meem.
