Belden HirschmannCov tes hauj lwm kev lag luam muab kev sib txuas lus txhim khu kev qha, qis-latency, thiab hloov pauv tau ib puag ncig rau cov kab ke xa xov hlau, txhawb nqa kev hloov pauv ntawm cov kab ke txav mus los xws li CBTC thiab TACS. Kev ua tau zoo tiag tiag thiab kev ruaj ntseg tau lees paub los ntawm kev siv kho vajtse rov ua dua, cov txheej txheem hloov pauv sai (xws li MRP / PRP / HSR), kev sib dhos sijhawm (PTP / TSN), thiab ntau txheej kev sib cais logical (VLAN / ACL). Lawv muaj peev xwm ua haujlwm ib puag ncig suav nrog ntau qhov kub thiab txias, tiv taus plua plav thiab xeb, thiab sib xws electromagnetic, txhawb nqa kev nthuav dav modular, kev kuaj mob deb, thiab kev tshuaj xyuas taug qab. Siv rau hauv ntau dua 120 qhov project hauv av, lawv muab "lub paj hlwb" ruaj khov thiab scalable rau lub subsystem xa xov, ua kom muaj kev nyab xeeb thiab ua haujlwm zoo.
Hauv kev siv network ntawm cov signaling systems hauv Suav teb txoj kev lag luam tsheb ciav hlau, cov kev daws teeb meem yeej ib txwm ntsib ntau yam teeb meem ntsig txog "kev nyab xeeb thiab kev ua haujlwm zoo":
Ib puag ncig lub cev thiab hluav taws xob hnyav: Ib puag ncig teeb tsa rau kev thauj mus los ntawm tsheb ciav hlau yog qhov nyuaj thiab hloov pauv. Cov tes hauj lwm kev lag luam tuaj yeem tiv taus kev co tas mus li, plua plav, av noo, thiab qhov kub thiab txias sib txawv ntawm sab hauv tsev thiab sab nraum zoov, ua kom cov cim meej thiab ruaj khov txawm tias muaj kev cuam tshuam hluav taws xob muaj zog.
Kev Ntseeg Tau thiab Muaj Tau: Los ntawm kev tsim cov khoom siv uas tsis tseem ceeb ntawm cov txheej txheem lub cev thiab cov txheej txheem network, ib qho chaw ua tsis tiav raug tshem tawm ntawm cov khoom siv kho vajtse mus rau qib protocol uas tsis tseem ceeb, muab kev sib txuas lus ze rau qhov tsis muaj kev cuam tshuam rau lub kaw lus teeb liab.
Kev Muaj Peev Xwm Sib Txuas Lus Tam Sim No: Rau cov haujlwm tseem ceeb xws li Kev Tiv Thaiv Tsheb Ciav Hlau Tsis Siv Neeg (ATPB), latency yuav tsum kwv yees tau txog qib millisecond lossis txawm tias microsecond. Lub network yuav tsum ua tiav latency qis kom ntseeg tau tias cov lus txib tswj tau xa tuaj rau hauv lub sijhawm teev tseg.
Kev Sib Txuas Lus Ua Ib Ke thiab Sib Koom Ua Ib Ke: Cov txheej txheem sib txuas lus niaj hnub CBTC (Computer-Assisted Train Control) tau tsim kom muaj kev thov rau lub network sib koom ua ke. Lub network yuav tsum xyuas kom muaj kev sib cais ruaj ntseg thaum nqa cov ntaub ntawv lag luam xa mus los ntawm ntau lub subsystems, lav qhov muaj thiab nkag tau ntawm cov ntaub ntawv tseem ceeb, ua kom yooj yim rau cov qauv thaum tswj kev ua haujlwm zoo.

Kev Txheeb Xyuas Kev Ua Siab Ntev Ib puag ncig
Muaj peev xwm ua haujlwm tau ntau qhov kub thiab txias (piv txwv li, -40 ℃ txog + 70 ℃), nrog rau kev tsim txheej rau kev tiv thaiv dej noo thiab xeb.
Kev Tiv Thaiv Tshuaj Lom Neeg thiab Pluav: Kev tiv thaiv qib siab ntawm IP65/67 rau kev siv sab nraum zoov, tiv thaiv cov plua plav nkag thiab xeb los ntawm cov pa phem.
Kev ntseeg siab mus sij hawm ntev: Raws li kev tsim MTBF siab, lub sijhawm nruab nrab ntawm kev ua tsis tiav (MTBF) tshaj 25 xyoo, nrog rau qee lub modules tshaj 100 xyoo.
Kev ruaj khov hluav taws xob: Muaj cov yam ntxwv siab sib xws electromagnetic thiab kev tsim hluav taws xob cais tawm, ua kom ntseeg tau tias lub teeb liab muaj kev ncaj ncees hauv qab kev cuam tshuam.
Kev ntseeg siab thiab muaj kev nyab xeeb siab:
Nyob rau sab kho vajtse, Belden cov khoom lag luam qib kev lag luam muaj cov khoom siv fais fab redundant thiab cov qauv tsim module redundant.
Nyob rau sab software, Belden muab ntau yam thev naus laus zis redundancy los xyuas kom meej tias tag nrho lub network muaj kev ntseeg siab, xws li IEC 62439 tus qauv Industrial Ring Redundancy Protocol (MRP) thiab dual-redundant ring network coupling technology, ua tiav network redundancy switching hauv 50ms.
Txhawb nqa cov modules modular hot-swappable, kev kuaj mob deb, thiab kev txij nkawm kwv yees, txo lub sijhawm kho (MTBF) ntau heev.
Low-latency, low-jitter real-time data transmission:
Cov kev daws teeb meem ib txwm siv cov txheej txheem sib dhos lub sijhawm xws li SNTP, NTP, thiab IEEE 1588 PTP los muab kev sib txuas lus millisecond, microsecond, lossis txawm tias nanosecond-level deterministic lav rau Ethernet.
Cov khoom siv tes hauj lwm qib kev lag luam uas txhawb nqa TSN thev naus laus zis ua kom ntseeg tau tias kev xa cov lus txib tswj tsheb ciav hlau thiab kev tso cai txav mus los hauv lub sijhawm txwv nruj.
Cov txheej txheem sib txuas lus tsis muaj kev cuam tshuam xws li PRP / HSR muab cov kev sib txuas lus tsis muaj kev cuam tshuam rau kev sib txuas lus hauv txoj kev thiab cov kab ke sib txuas lus.
Cov qauv kev sib txuas lus uas muaj ntau txheej txheem, kev tiv thaiv tob tob:
Npog ntau yam Layer 2 virtual LANs, suav nrog tus qauv VLANs, chaw nres nkoj VLANs, protocol-based VLANs, suab VLANs, MAC/IP subnet-based VLANs, thiab Private VLANs, ua tau raws li cov kev xav tau sib cais ntawm cov kev pabcuam sib txawv hauv thaj chaw kab.
Kev them nqi ntawm cov txheej txheem kev teeb tsa txheej txheem txheej txheem 3 xws li RIP v1 / v2, OSPF v2, kev teeb tsa static, thiab PIM-DM / SM / SSM muab kev txhawb nqa tseem ceeb rau kev sib txuas lus txhim khu kev qha thiab ua haujlwm tau zoo thoob plaws thaj tsam thiab ntau qib.
Kev siv cov thev naus laus zis ACL ua ke, suav nrog Basic ACL, MAC-based ACL, IP-based ACL, Time-based ACL, thiab VLAN-based ACL, tsim kom muaj kev ruaj ntseg peb-seem thiab kev tswj hwm tsheb khiav zoo thiab dynamic rau lub kaw lus signaling los ntawm ntau qhov ntev xws li lub sijhawm, qhov chaw (VLAN), kev coj, thiab bandwidth.
Kev vam khom rau lub kaw lus tiv thaiv tob tob uas muaj kev txheeb xyuas firmware ntseeg siab, kev tswj hwm kev nkag mus ntse, thiab kev tswj hwm txoj cai dynamic, kev ncaj ncees thiab kev ntseeg siab ntawm lub kaw lus tau lees paub tag nrho.
Hauv kev txhim kho tas mus li thiab kev hloov pauv ntawm cov kab ke qhia kev tsheb ciav hlau,Belden HirschmannCov kev daws teeb meem kev lag luam hauv network tau dhau los ua lub hauv paus ruaj khov rau kev tsim kho digital hauv kev lag luam. Peb cov kev daws teeb meem tau siv rau ntau dua 120 qhov project subway signaling system thoob plaws lub tebchaws; cov kev coj ua dav dav no tau ua rau peb nkag siab tob. Mus tom ntej tsis tu ncua, Belden Hirschmann txuas ntxiv mob siab rau kev tsim kom muaj lub paj hlwb txhim khu kev qha rau kev lag luam tsheb ciav hlau los ntawm kev siv cov thev naus laus zis sib txuas tshiab, txuas ntxiv tsav tsheb txhim kho kev tsav tsheb kev nyab xeeb thiab kev ua haujlwm zoo, thiab xyuas kom meej tias kev thauj mus los hauv nroog du.
