3 Cov twj tso kua roj hauv lub lag luam khiav lag luam chaw nruab nrab kho vajtse tsim
Txoj kev sib txuas lus hauv kev sib txuas lus hauv kev sib txuas lus, rau cov khoom siv rau ntawm qhov chaw ntawm qhov chaw tso kua roj twj, kom ua tau raws li lub sijhawm tshawb nrhiav hauv online thiab lub sijhawm sojntsuam ntawm lub sijhawm ua haujlwm ntawm qhov kev pab cuam nyob rau hauv qhov chaw haujlwm khiav haujlwm ntawm cov chaw haujlwm engineer,
Cov cuab yeej tswj nyob rau ntawm qhov chaw ntawm qhov chaw tso kua dej tau txuas mus rau hauv Internet pej xeem sib chaws los ntawm lub wired lossis qhov chaw WIFI overlay system, los yog nws tuaj yeem raug txuas mus rau qhov chaw pabcuam haujlwm hauv kev siv internet.
Kev sib txuas lus sib txawv, kev sib txuas ntawm cov twj tso kua mis, ib txhij sib txuas rau ntau qhov chaw ntawm cov chaw hauv online ntawm kev tshawb nrhiav, kev ceeb toom ntxov, kev kho, kev hloov kho, thiab lwm yam. Qhov tseem ceeb yog mus cuag qhov kev pab cuam qib nkag mus rau tus programmer xws li, download program, Kev tshawb nrhiav hauv internet Nws tsis yog qhov teeb meem uas muaj teeb meem, qhov tsim kom tau nyiaj ntau rau txhua qhov kev poob haujlwm lossis kev debugging, thiab paub txog cov ntaub ntawv tam sim no, paub cov ntse thiab networked IoT, thiab paub txog cov ntaub ntawv cia los ntawm lub chaw nruab nrab ntawm lub chaw nruab nrab. Cloud computing, kev koom ua ke ntawm cov cuab yeej tswj kev lag luam thiab IT Internet nrog tiag industrialization thiab kev tshaj tawm.
4 Cov twj tso kua roj hauv lub chaw nres tsheb khiav lag luam tsim software tsim
4.1 Kev tsim tus qauv
Nyob hauv txoj kev sib txuas lus ruaj ntseg, software thiab kho vajtse tsim los ntawm kev sib txuas lus rau parsing, encryption thiab routing, switching, firewall, thiab lwm yam. Thaum kis tau tawm ntawm cov pej xeem network, S-Link raws tu qauv muaj nplooj siab mus xa cov ntaub ntawv muaj. Lub chaw ruaj khov ruaj khov ruaj ntseg. Nyob hauv qhov kev pabcuam hauv lub lag luam, tus SY-RSCM siv rau kev kuaj thiab kev kuaj xyuas, thiab tom qab ntawd ces qhov tseeb thiab tsis muaj kev ruaj ntseg yog xa mus rau lub hom phiaj.
4.2 Kev tsim kev nyab xeeb
Los ntawm lub system, cov chaw tswj kev lag luam ntawm kev siv lub tshuab puv ntom ntws ntawm qhov chaw nruab nrag tau pom tseeb: kev txhim kho, kev ceeb toom ntxov, kev debugging, kuaj xyuas, txhim kho, thiab ua kom paub txog kev ruaj ntseg hauv cov txheej txheem kev sib txuas lus, uas yog nyob rau hauv cov nram qab no plaub yam:
(1) Tsab ntawv thov ntawm qhov chaw ruaj ntseg kev sib txuas lus tsis yog pom tseeb ntawm kev nthuav cov ntaub ntawv tawm los ntawm lub zos thaj tsam network mus rau thoob plaws cheeb tsam network, tab sis kuj muaj nws cov khoom siv hluav taws xob ua haujlwm. Nws tuaj yeem tshawb xyuas thiab saib xyuas cov ntaub ntawv pob ntawv ntawm txhua txheej los siv cov ntsiab lus ntxig rau, nkag mus rau kev nkag mus, kev tiv thaiv ntawm kev tiv thaiv thiab lwm yam haujlwm. Qhov kev tiv thaiv S-txuas tuaj yeem hloov dua siab tshiab rau cov ntaub ntawv muaj peev xwm.
(2) Qhov kev ruaj ntseg hauv kev sib txuas ntawm cov chaw taws teeb hauv kev ruaj ntseg kuj muaj kev qhia tias yog leejtwg tiag, uas muaj peev xwm paub tau cov cuab yeej cuab tam thiab cov neeg siv kev pov thawj, kom cov ntaub ntawv muaj peev xwm tsuas xa mus ncaj qha rau hauv daim ntawv pov thawj, thiab tus neeg teb xov tooj nrog daim ntawv tso cai tso cai tau nyeem cov ntaub ntawv.
(3) Cov ntaub ntawv raug xa mus rau hauv Internet, siv S-Link raws tu qauv. Qhov kev cai lij choj no yog tsim los rau cov ntaub ntawv muaj kev hloov WAN. Nws yog raws li cov tsis yog universality ntawm tus qauv kev cai, nrog rau cov kev cai tshwj xeeb ntawm cov fieldbus uas muaj kev lag luam, ib qho tseem ceeb rau pejxeem hom kev tsim tshwj xeeb nrog lub hom phiaj ntawm kev sibtham thiab kev ruaj ntseg raws li lub hom phiaj tseem ceeb. RSA algorithm tau txais kev pab, thiab tus yuam sij yog txog li 1536. Ib qho tseem ceeb-asymmetric yawm sij, encrypted nrog cov pej xeem yuam thiab tus yuam sij. Daim ntawv thov ntawm S-txuas kev cai tiv thaiv kom tsis pub leej twg paub, authenticity thiab kev ntseeg ntawm cov ntaub ntawv industrial WAN.
(4) Cov txheej txheem siv tag nrho siv virtual LAN VLAN technology, thiab txhua lub cuab yeej sib faib ua ib qhov network hauv zos kom ua tau raws li cov cai ntawm lub sij hawm muaj cov ntaub ntawv xa tawm. Nyob rau tib lub sijhawm, cov ntaub ntawv muaj peev xwm tsuas yog xa mus rau VLAN nkaus xwb, tiv thaiv kev tshaj tawm cov ntaub ntawv hauv Is Taws Nem thiab kev txhim kho kev ruaj ntseg ntawm industrial ntaub ntawv kis.
