Dab tsi yog qhov txawv ntawm PLC thiab kev lag luam PC

Tsav los ntawm nthwv dej ntawm kev lag luam 4.0, automation tau hloov kho los ntawm kev xaiv los txhim kho kev ua lag luam rau kev ua lag luam muaj sia. Lub ntiaj teb tsim kev lag luam yog xa cov txheej txheem siab los txhim kho cov raug, txo qis nqi thiab ua kom cov nqi kho kom zoo. Cov tswj hwm logic (plcs) thiab muaj cov PCS (IPCs) yog ob qho tseem ceeb thev naus laus zis hauv cov txheej txheem no. Txawm hais tias ob qho tib si ntawm lawv pab muaj kev tswj hwm kev tswj hwm kev tswj hwm, muaj cov qauv kev ua haujlwm, cov yam ntxwv ua haujlwm thiab cov qauv ntawm kev thov.

Tus plc yog dab tsi?

PLC (programmable logic maub los) yog lub khoos phis tawm tshwj xeeb tsim rau cov khoom lag luam muaj tshuab los ntawm kev ua haujlwm ntawm cov haujlwm tiag tiag. Cov khoom kho vajtse yog modular thiab muaj cov chav ua haujlwm ua hauv nruab nrab (CPU), cov lus tawm tswv yim / i / o) modules, thiab chav ntim khoom siv. Tsis zoo li General-hom phiaj siv computer yog qhov ua haujlwm tiag tiag (RTOs)

Cov qauv kho vajtse thiab cov ntawv thov raug

Tej yam me me plc: compact loj (xws li qhov loj ntawm lub xib teg ntawm koj txhais tes), haum rau ib qho khoom siv tswj, xws li pib nres log tswj ntawm lub hnab ntim me me.

Modular PlC: Txhawb kev nthuav dav ntawm I / o. Digital (piv txwv li cov kab sib txuas lus), haum rau cov txheej txheem sib txuas lus, piv txwv li. Kev sib koom tes kev tswj ntawm cov riam phom loj hauv kev ua rooj sib txoos hauv tsheb.

Rackmount PLC: Nrog kev ua haujlwm muaj zog thiab nthuav dav hauv cov tshuab loj (xws li cov chaw tswj hwm loj (DCS) hauv cov petrochemical teb.

Qhov Zoo ntawm PLCS

Kev ntseeg siab: Fanus ua haujlwm, muaj qhov kub ua haujlwm (-40 ℃) thiab kev ua haujlwm ntsuas rau kev ua haujlwm ruaj khov xws li plua plav thiab roj.

Siab tiag tiag-lub sij hawm: raws li scanning lub voj voog sib zog ua ke, nws ua kom cov lus qhia kev tswj hwm, haum rau lub sijhawm-rhiab scenarios (E.G. High-ceev filling ntau txoj kab ntau lawm).

Tsawg lub cajmeem pib pib ua haujlwm xws li tus ntaiv lub cav, ua kom nws yooj yim rau cov kws ua haujlwm tau pib sai.

Txwv ntawm plcs

Kev ua kom tsawg ua lub zog: tsuas txhawb cov haujlwm logic yooj yim, nyuaj ua cov haujlwm nyuaj xws li siv lub tshuab kev kawm thiab cov ntaub ntawv tsom kwm.

Ib leeg-ua haujlwm: tsom rau kev lag luam tswj, kev koom ua ke nrog nws cov (E.G. YEP, MES) yuav tsum tau ib lub vev xaib ntxiv.

Cov nqi siab ntawm cov tshuab ua ke: thaum muaj ntau tus lej ntawm I-/ 1 lossis kev sib txuas lus lossis kev sib txuas lus los hloov pauv, tus nqi kho mob nce ntxiv.

Dab tsi yog ib qhoMuaj PC?

IbMuaj PCyog lub khoos phis tawj txhim kho raws li General-hom phiaj PC architecture, tsim rau kev lag luam kev lag luam, khiav Windows, Linux, thiab lwm yam kev ua haujlwm loj. Nrog rau kev txhim kho ntawm semiconductor thev naus laus zis, IPC tsis tuaj yeem ua tiav cov haujlwm ntawm GPU (acស processload) Nws cov tseem ceeb tus nqi yog los txo cov khoom siv kho vajtse hauv lub Hoobkas los ntawm "kev sib koom ua haujlwm", ib IPC tuaj yeem paub cov khoom tswj, cov ntaub ntawv tau txais thiab kev sib txuas lus huab tib lub sijhawm.

Cov Khoom Kho Vajtse thiab Kev Xa Khoom

Anti-hars ib puag ncig tsim: tau txais kev txawj ntse thiab kev ntsuas dej tsis tau, thiab muaj qee cov qauv hluav taws xob tuaj yeem ua haujlwm hauv -25 ℃ ~ 60 ℃ dav ib puag ncig.

Kev hloov kho qhov peev xwm nthuav dav: muab cov pcie slot, m.2 interface, thiab txhawb nqa kev nthuav dav ntawm lub tshuab pom kev zoo, kev tswj hwm neeg hlau, thiab lwm yam.

Cov hau kev teeb tsa teeb tsa teeb tsa: Kev txhawb nqa kev tsheb ciav hlau (haum rau kev tswj khoom), Vesa phab ntsa-mounting (haum rau kev ua haujlwm consoles) lossis khib-mounting (cov ntaub ntawv chaw teeb meem).

Qhov zoo ntawmKev siv computers

Muaj peev xwm ua tau muaj zog ua tiav: nruab nrog Intel Core yog muaj cov lus, thiab lwm yam selthon thiab lwm yam kev xa tawm ntawm cov qauv kawm sib txawv (xws li Yolo Phiaj Nrhiav tau).

Nws yog / ot convergence muaj peev xwm: kev txhawb nqa ib txwm muaj rau kev lag luam muaj kev cuam tshuam nrog EPC UAE, thiab lwm yam, thiab lwm yam.

Yooj yim saib xyuas cov chaw taws teeb: Cov chaw kho chaw taws teeb thiab kho kom zoo dua tuaj yeem paub los ntawm cov cuab yeej xws li TEAMVIEUER thiab VNC, txo tus nqi kho.

Kev txwv ntawm cov khoos phis tawj

Kev ua haujlwm siab pib: Tus nqi ntawm High-kawg IPc tuaj yeem ua kaum txhiab daus las, deb tshaj li cov plc me me plc.

Yuav muaj kev nyab xeeb siab: firewals, intrusion nrhiav cov software (ID) thiab kev lag luam antivirus

Kev yoog raws ib puag ncig yog kev teeb tsa-vam khom: qee qhov tsis muaj kev tiv thaiv hauv huab lossis cov plua plav siab.

Qhov sib txawv ntawm cov PC VS PLC?

Kev ua haujlwm thiab lub sijhawm

PLC: nyob ntawm lub sijhawm ua haujlwm tiag tiag (RTOs), yog haum rau millisecond precision tswj cov haujlwm (piv txwv li pwm kaw sijhawm ntawm kev txhaj tshuaj molding tshuab).

IPC: Khiav ib lub hom phiaj-lub hom phiaj ua haujlwm, nws yuav tsum paub cov haujlwm tiag tiag nrog cov kev xav tau me me (xws li rov ua haujlwm me me)

Cov Lus Txheej Txheem thiab Kev Tsim Kho Ecology

PLC: ntaiv Logic (ntaiv Logir (FBD Block) yog lub ntsiab, feem ntau ntawm cov ecology raug kaw, tab sis qhov ruaj khov yog muaj zog.

IPC: Txhawb C / C ++, sej, sej, thiab lwm yam kev siv hluav taws xob (xws li MatlB Industrial Efficiency thiab muaj zog nthuav tawm.

Nqi Qauv

Lub Nruab Nrab: Plcs muab cov txiaj ntsig tseem ceeb. Piv txwv li, rau qhov project me me tswj 10 digital inputs / resplecks, ib plc tov yuav muaj tsawg li 1 / 3 tus nqi ntawm IPC.

Cov tshuab complex: IPCS muaj cov nqi siab dua ntawm cov tswv cuab (TCO). Thaum kuaj pom, cov ntaub ntawv khaws cia, thiab cov kev sib txuas lus huab yuav tsum tau sib xyaw, IPC muaj kev sib xyaw ua ke ntawm cov khoom siv kho vajtse, cabling, thiab txij nkawm.

Kev ruaj ntseg thiab kev ntseeg tau

PLC: Cov ntawv kos ib txwm tsis tshua muaj rau Cyberattacks, tab sis raws li kev lag luam hauv internet ntawm tej yam (iiot) dhau los ua kev sib tw, ethernet-enlabe yuav tsum tau tso cov firewalls ntxiv.

Cov ntaub ntawv raug: StuxNet tus kab mob (2010) Tawm tsam Iranian Cov Chaw Nuclear los ntawm PlC Clarnerability, qhia txog kev pheej hmoo cncer kev pheej hmoo.

IPC: Cia siab rau software tiv thaiv cov txheej txheem, system PARDES thiab Virus databases yuav tsum tau hloov kho tsis tu ncua. Txawm li cas los xij, kev lag luam IPCs feem ntau muaj built-in tpm 2.0 chips, txhawb nqa cov qauv siv, thiab ua raws li ISO / IECH 27001 cov ntaub ntawv kev nyab xeeb.

Hardware Architecture thiab Scalability

qho loj dav Plc Li cas rau IPC Processor Kev tswj tshwj xeeb tswj cov chips (piv txwv li ti dsp, Intel atom) Lub Hom Phiaj X86 / Caj Npab Processors (E.G. Intel I5 / I7) Chaw ntim khoom Flash + EEPROM (Hwj chim tsis ua haujlwm los tuav cov ntaub ntawv) SSD /dd, txhawb nqa cov ntaub ntawv rho tawm Kuv / o interface Kev Muaj Kev Sib Koom Tshwj Xeeb Sib Tham (E.g., Terminal Blocks, M12 Connectors) USB / Landmi / lan tshaj, txhawb cov qauv kev lag luam Kev nthuav dav Modular I / o nthuav dav (xav kom cov khoom lag luam-tshwj xeeb) Pcie / USB nthuav dav nrog kev txhawb nqa rau cov khoom siv thib peb
