Qhov muaj pes tsawg leeg thiab cov haujlwm ntawm kev sib txuas lus kev sib txuas lus
- Dab tsi regsystems tsuas yog pib kev tsheb nqaj hlau?
The railway communication system is mainly composed of transmission systems, telephone exchange systems, data communication systems, and mobile communication systems. The transmission system is the foundation of communication, and optical fiber transmission is commonly used. The railway - dedicated optical cable network has the advantages of large capacity, low attenuation, and strong anti - interference ability. The telephone exchange system realizes voice communication within the railway and with the sab nraud, npog cov xov tooj, cuam tshuam rau cov ntaub ntawv sib txuas lus thiab cov ntaub ntawv sib txuas lus rau cov ntaub ntawv kev sib txuas lus, txhawb nqa cov ntaub ntawv sib txuas lus thiab kev sib txuas lus xwm ceev {{9 {9 {9 {9 {9 {9 {9 {9 {9 {9 {9 {9
- Lub luag haujlwm ntawm kev tsheb ciav hlau ua haujlwm li cas hauv kev cob qhia kev tswj hwm kev ua haujlwm?
Cov kev sib txuas lus ua ob - txoj kev ntaub ntawv cov ntaub ntawv kis tau ntev ntawm lub tsheb ciav hlau tswj, nrawm nrawm, tiv thaiv kev qhia tawm - ntawm - tswj tau los ntawm Kev cuam tshuam sib txuas lus . Nyob rau hauv ntxiv, nws kuj tseem pab lub tsheb ciav hlau tswj kev ua haujlwm ntawm kev qhia ua haujlwm ntau thiab kev txawj ntse.
- Txoj kev tsheb nqaj hlau puas ua kom muaj kev ntseeg siab thiab kev nyab xeeb ntawm kev sib txuas lus?
Kev siv tshuab hluav taws xob rov qab tau txais los teeb tsa cov khoom siv backup thiab hloov kho cov ntaub ntawv kev sib txuas lus thaum muaj cov ntaub ntawv kev phom sij muaj kev phom sij hauv lub sijhawm thaum muaj xwm txheej ceev, thiab cov khoom sib txuas lus thaum muaj xwm ceev yog tsim kom muaj kev sib txuas lus tsis muaj xwm txheej ceev.
- Dab tsi yog qhov sib txawv ntawm GSM - R system thiab cov tshuab sib txuas lus sib txuam?
GSM - R yog tshwj xeeb tsim rau kev tsheb ciav hlau, nrog kev sib txuas lus ntawm cov neeg sib txuas lus thiab kev sib txuas lus sib xws los ua kev sib txuas lus ntawm cov kab kev tsheb ciav hlau los ua kom muaj kev tiv thaiv pab pawg ua ke raws cov kab . Nyob rau hauv cov nqe lus ntawm kev ntseeg tau, nws siv ntau yam kev ua txhaum cai thiab kev sib koom tes zoo dua li cov kev xav tau ntawm cov tsheb ciav hlau txav ntawm kev kub ceev {}}
- Dab tsi yog qhov kev txhim kho yav tom ntej kev txhim kho ntawm kev sib txuas lus kev tsheb nqaj hlau?
Yav tom ntej, nws yuav tsim kho rau kev loj hlob siab - kev ua haujlwm tau txais kev sib txuas lus thiab kev sib koom ua ke {{} txhawb kev sib koom ua ke ntawm kev sib koom ua ke nrog Is Taws Nem ntawm cov khoom thiab cov ntaub ntawv loj, thiab tsim kev sib txuas lus ntse ntawm cov ntaub ntawv ntawm kev sib txuas lus ntawm kev ua haujlwm ntse.
