Qhov chaw nres nkoj I/O ntawm lub tshuab computer zoo li cas?
Raws li tus choj rau cov khoos phis tawj muaj kev cuam tshuam nrog cov khoom siv sab nraud, I / O cov chaw nres nkoj ua lub luag haujlwm tseem ceeb thiab cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ruaj ntseg ntawm tag nrho cov kab ke. Yog li ntawd, kev nkag siab tob txog lawv cov hom thiab cov yam ntxwv yog qhov tseem ceeb rau kev sib koom ua ke thiab cov neeg ua haujlwm. Kab lus no yuav tshawb txog cov hom thiab cov yam ntxwv ntawm cov khoos phis tawj I / O chaw nres nkoj thiab lawv lub luag haujlwm tseem ceeb hauv cov ntawv thov kev lag luam.
Cov Lus Qhia

1. Txheej txheem cej luam ntawm I/O ports
I/O ports, los yog input thiab output interfaces, yog raws rau industrial computers tau txais thiab xa cov ntaub ntawv. Cov kev sib txuas no tuaj yeem txuas ntau yam sensors, actuators, kev sib txuas lus, thiab lwm yam kom ua tiav cov ntaub ntawv sau, tswj cov lus txib, thiab saib xyuas cov xwm txheej.
2. Hom I/O ports
3. I/O chaw nres nkoj yam ntxwv
1. Cov yam ntxwv ntawm hluav taws xob: suav nrog kev khiav hauj lwm voltage, tam sim no, impedance, thiab lwm yam. Cov kev txwv no txiav txim siab hom teeb liab thiab qib ntau yam uas I / O chaw nres nkoj tuaj yeem ua tau.
2. Lub cev loj: Lub cev loj thiab cov duab ntawm I / O chaw nres nkoj, xws li DB9, DB25, RJ45, thiab lwm yam, cuam tshuam rau kev xaiv cov khoom sib txuas thiab kev yooj yim ntawm kev xaim.
3. Hom teeb liab: Hom teeb liab txhawb nqa los ntawm I / O chaw nres nkoj, xws li cov teeb liab digital, analog teeb liab, cov ntaub ntawv serial, thiab lwm yam, txiav txim siab nws daim ntawv thov teb thiab hom khoom siv txuas nrog.
4. Kev tiv thaiv mechanism ntawm I/O chaw nres nkoj
1. Kev rho tawm hluav taws xob photoelectric: Kev sib cais hluav taws xob tau ua tiav los ntawm photoelectric couplers los tiv thaiv I / O cov chaw nres nkoj los ntawm hluav taws xob poob siab thiab suab nrov cuam tshuam.
2. Kev tiv thaiv overvoltage: Transient voltage suppressors los yog diode arrays yog siv los tiv thaiv overvoltage puas rau I/O ports tshwm sim los ntawm xob laim ntaus los yog fais fab mov fluctuations.
