Lub khoos phis tawj tswj kev lag luam yog lub khoos phis tawj ua haujlwm siab uas muaj lub luag haujlwm saib xyuas thiab tswj ntau yam khoom siv qis dua hauv cov txheej txheem kev lag luam, suav nrog PLCs (programmable logic controllers), sensors, actuators, thiab lwm yam uas cuam tshuam ncaj qha nrog cov txheej txheem kho tshuab.

Hauv cov txheej txheem automation niaj hnub no, cov khoos phis tawj hauv kev lag luam ua lub luag haujlwm ntawm lub hlwb, thiab lawv cov kev ua tau zoo cuam tshuam ncaj qha rau kev ua haujlwm ruaj khov ntawm tag nrho lub cev. Raws li qhov interface tseem ceeb rau kev sib txuas lus cov ntaub ntawv, kev tsim qauv ntawm lub network port nyob hauv txoj haujlwm tseem ceeb hauv cov khoos phis tawj hauv kev lag luam. Tsab xov xwm no yuav tshawb nrhiav qhov tseem ceeb thiab cov ntawv thov ntawm kev tsim qauv network computer hauv kev lag luam.

1. Hom roj teeb

Kev xaiv hom roj teeb yog qhov tseem ceeb tshaj plaws uas cuam tshuam rau kev ua haujlwm ntawm lub laptop. Tam sim no, cov roj teeb lithium-ion (Li-ion) thiab lithium polymer (Li-po) tau dhau los ua tus qauv rau cov khoos phis tawj laptop hauv kev lag luam vim lawv lub zog ceev ceev, tus nqi tso tawm tus kheej qis thiab lub neej ntev.

Hauv kev siv tshuab niaj hnub no, cov khoos phis tawj tswj kev lag luam thiab PLCs ua lub luag haujlwm tseem ceeb. Raws li cov khoom tseem ceeb ntawm lub kaw lus tswj, lawv ua haujlwm ua ke los saib xyuas thiab tswj cov txheej txheem tsim khoom. Tsab xov xwm no yuav qhia txog kev siv ua ke ntawm cov khoos phis tawj tswj kev lag luam thiab PLCs kom ntxaws.

Kev siv cov khoos phis tawj hauv kev lag luam logistics sorting feem ntau yog pom tseeb hauv nws cov peev xwm ua cov ntaub ntawv muaj zog thiab kev ua haujlwm ruaj khov, uas tuaj yeem txhim kho qhov ua tau zoo thiab qhov tseeb ntawm kev sorting logistics. Nws qhov kev sib raug zoo thiab kev nthuav dav kuj ua rau nws kev koom ua ke thiab daim ntawv thov hauv logistics sorting system yooj yim dua thiab yoog tau.

Vim yog kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, cov khoos phis tawj embedded tau siv dav hauv txhua qhov chaw ntawm lub neej vim lawv cov kev ua haujlwm zoo thiab cov yam ntxwv tshwj xeeb. Tsab xov xwm no lub hom phiaj yog cais thiab tshuaj xyuas cov khoos phis tawj embedded los ntawm tsib qhov ntev.

Hauv kev tsim thiab tsim cov txheej txheem ntawm cov khoos phis tawj hauv kev lag luam, qhov ruaj khov thiab kev ntseeg tau ntawm cov khoos phis tawj hauv kev lag luam muaj feem cuam tshuam ncaj qha rau kev ua haujlwm zoo thiab kev nyab xeeb ntawm tag nrho cov txheej txheem kev lag luam. Yog li ntawd, kev txheeb xyuas thiab kev ua kom zoo dua cov yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov khoom siv khoos phis tawj hauv kev lag luam yog qhov tseem ceeb heev rau kev txhim kho cov khoom zoo thiab kev txaus siab ntawm cov neeg siv khoom.
Tsab xov xwm no yuav tshawb nrhiav tsib yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov khoom siv computer hauv kev lag luam: tib neeg, tshuab, khoom siv, cov txheej txheem, thiab ib puag ncig.

Cov khoos phis tawj lag luam muaj ntau qhov zoo nrog cov chaw nres nkoj serial ua ke. Tsab xov xwm no yuav tsom mus rau qhov zoo ntawm cov khoos phis tawj lag luam nrog cov chaw nres nkoj serial ua ke hauv kev sib txuas lus cov ntaub ntawv.

Hauv kev lag luam automation thiab kev ua cov ntaub ntawv, qhov ruaj khov thiab lub zog xam ntawm cov khoos phis tawj kev lag luam yog cov yam tseem ceeb hauv kev txhawb nqa cov haujlwm nyuaj thiab kev suav lej zoo. Nrog rau kev txhim kho thev naus laus zis, dual-CPU kev lag luam khoos phis tawj tau tshwm sim, muab cov kev daws teeb meem rau cov kev xav tau kev suav lej siab. Yog li, dual-CPU kev lag luam khoos phis tawj yog dab tsi? Tsab xov xwm no yuav qhia cov lus teb.

Lub khoos phis tawj lag luam 232 interface yog tus qauv kev sib txuas lus serial nrog keeb kwm ntev thiab siv dav hauv kev tswj hwm kev lag luam. Tsab xov xwm no lub hom phiaj yog qhia txog kev paub yooj yim ntawm lub khoos phis tawj lag luam 232 interface thiab tshawb nrhiav nws txoj hauv kev ua haujlwm, txoj kev sib txuas lub cev thiab cov xwm txheej ntawm daim ntawv thov.
