UBelden HirschmannAmanethiwekhi ezimboni ahlinzeka ngesisekelo sokuxhumana esithembeke kakhulu, esiphansi, nesivumelana nemvelo sezinhlelo zokubonisana zokuhamba ngesitimela, esisekela ukuvela kwezinhlelo zamabhulokhi ahambayo njenge-CBTC ne-TACS. Ukusebenza nokuphepha kwesikhathi sangempela kuqinisekiswa ngokusebenzisa i-hardware redundancy, amaphrothokholi okushintsha okusheshayo (njenge-MRP/PRP/HSR), ukuvumelanisa isikhathi (PTP/TSN), kanye ne-multi-layer logical isolation (VLAN/ACL). Anamandla okubekezelelana kwemvelo afaka phakathi ububanzi bokushisa, ukumelana nothuli nokugqwala, kanye nokuhambisana kwe-electromagnetic, ukusekela ukwanda kwe-modular, ukuxilongwa okukude, kanye nokuhlolwa okulandelekayo. Asetshenziswa kumaphrojekthi angaphezu kuka-120 esitimela esingaphansi komhlaba, ahlinzeka "ngohlelo lwezinzwa" oluzinzile nolunwebekayo lwesistimu encane yokubonisa, ukuqinisekisa ukuphepha nokusebenza kahle kokusebenza.
Ekusetshenzisweni kwenethiwekhi kwezinhlelo zokubonisana embonini yezokuthutha izitimela yaseShayina, izixazululo zihlala zibhekene nezinselele eziningi ezihlobene "nokuphepha nokusebenza kahle":
Izindawo eziqinile zomzimba kanye nezama-electromagnetic: Indawo yokufaka ezokuthutha ngesitimela iyinkimbinkimbi futhi iyahlukahluka. Amanethiwekhi ezimboni angamelana nokudlidliza okuqhubekayo, uthuli, umswakama, kanye nokushintshashintsha kwezinga lokushisa phakathi kwezindawo zangaphakathi nezangaphandle, okuqinisekisa izimpawu ezicacile nezizinzile ngisho nangaphansi kokuphazamiseka okukhulu kwama-electromagnetic.
Ukuthembeka Nokutholakala: Ngokuklama okungadingekile ezingqimbeni ezibonakalayo nezenethiwekhi, amaphuzu okuhluleka okukodwa ayasuswa kusukela kuhadiwe kuya ezingeni lephrothokholi elingadingekile, okunikeza isiqinisekiso sokuxhumana esingaphazanyiswa kakhulu sohlelo lokubonisana.
Amandla Okuxhumana Ngesikhathi Sangempela: Emisebenzini ebalulekile efana nokuvikelwa kwesitimela okuzenzakalelayo (i-ATPB), ukubambezeleka kumele kubikezelwe ezingeni le-millisecond noma ngisho nele-microsecond. Inethiwekhi kufanele ifinyelele ukubambezeleka okuphansi ukuqinisekisa ukuthi imiyalo yokulawula ilethwa ngaphakathi kwewindi lesikhathi esibekiwe.
Ipulatifomu Yokuxhumana Ehlanganisiwe Nehlanganisiwe: Izinhlelo zokubonisana ze-CBTC (Computer-Assisted Train Control) ezisekelwe kwezokuxhumana zanamuhla zidale isidingo senethiwekhi ehlanganisiwe. Inethiwekhi kufanele iqinisekise ukuhlukaniswa okuphephile ngenkathi ithwala ukudluliswa kwedatha yebhizinisi phakathi kwezinhlelo ezingaphansi ezahlukene, iqinisekise ukutholakala nokufinyeleleka kwedatha eyinhloko, yenza lula ukwakheka kwayo ngenkathi igcina ukusebenza kahle.
I-Belden Hirschmann Industrial Network kanye Nokujwayela Uhlelo Lokusayina
Ukuqinisekiswa Okuphelele Kokubekezelelana Kwemvelo
Iyakwazi ukusebenza ebangeni elibanzi lokushisa (isb., -40℃ kuya ku-+70℃), ngomklamo wokumboza wokumelana nomswakama nokugqwala.
Ukuvikelwa Kwamakhemikhali Nothuli: Isilinganiso sokuvikelwa esiphezulu se-IP65/67 sokusetshenziswa ngaphandle, okuvimbela ukungena kothuli nokugqwala okuvela kumagesi ayingozi.
Ukuthembeka kwesikhathi eside: Ngokusekelwe kumklamo we-MTBF ophezulu, isikhathi esimaphakathi phakathi kokwehluleka (i-MTBF) sidlula iminyaka engama-25, kanti amanye amamojula adlula iminyaka eyi-100.
Ukuzinza kukagesi: Kufaka ukuhambisana kukagesi okusezingeni eliphezulu kanye nomklamo wokuhlukanisa ugesi, okuqinisekisa ubuqotho besiginali ngaphansi kokuphazamiseka.
Ukuthembeka okuphezulu kanye nokutholakala:
Ngasohlangothini lwehadiwe, imikhiqizo yezinga lezimboni yaseBelden ifaka izinsiza zikagesi ezingadingeki kanye nemiklamo yamamojula angadingeki.
Ngasohlangothini lwesofthiwe, iBelden inikeza ubuchwepheshe obuhlukahlukene bokuphindaphindwa kwedatha ukuqinisekisa ukuthembeka kwenethiwekhi yonke, njenge-IEC 62439 standard Industrial Ring Redundancy Protocol (MRP) kanye nobuchwepheshe bokuxhumanisa inethiwekhi yendandatho ephindwe kabili, okufeza ukushintshana kwenethiwekhi okuphindaphindwa kwedatha ngaphakathi kwama-50ms.
Isekela amamojula ashintshashintshayo aguquguqukayo, ukuxilongwa okukude, kanye nokugcinwa kokubikezela, okunciphisa kakhulu isikhathi esimaphakathi sokulungisa (i-MTBF).
Ukubambezeleka okuphansi, ukudluliswa kwedatha kwesikhathi sangempela okuphansi:
Izixazululo ezivamile zisebenzisa amaphrothokholi okuvumelanisa isikhathi njenge-SNTP, i-NTP, kanye ne-IEEE 1588 PTP ukuhlinzeka ngeziqinisekiso zokuxhumana eziqondile ze-millisecond, microsecond, noma ngisho ne-nanosecond zezinga le-Ethernet.
Imikhiqizo yenethiwekhi yezinga lezimboni esekela ubuchwepheshe be-TSN iqinisekisa ukulethwa kwemiyalo yokulawula isitimela kanye nezimvume zokuhamba ngaphakathi kwemingcele yesikhathi esiqinile.
Izinqubo zokuxhumana ezingafuneki zokushintsha okungenamthungo ezifana ne-PRP/HSR zihlinzeka ngeziteshi zokuxhumana ezingaphazanyiswa zokuxhumana ezingaphakathi kwebhodi kanye nezinhlelo ezixhumene.
Ukwakhiwa kokuxhumana okunezigaba ezinengqondo, okujulile nokuzivikela:
Ihlanganisa ama-LAN ahlukahlukene e-Layer 2 virtual, kufaka phakathi ama-VLAN ajwayelekile, ama-VLAN asekelwe echwebeni, ama-VLAN asekelwe kuphrothokholi, ama-VLAN ezwi, ama-VLAN asekelwe ku-MAC/IP subnet, kanye nama-VLAN azimele, okuhlangabezana nezidingo zokuhlukanisa ezinengqondo zezinsizakalo ezahlukene ngaphakathi kwendawo yomugqa.
Ukumbozwa kwezinqubo zokuqondisa ze-Layer 3 njenge-RIP v1/v2, i-OSPF v2, i-static routing, kanye ne-PIM-DM/SM/SSM kunikeza ukwesekwa okuyisisekelo kokuxhumana okuthembekile nokusebenzayo kuzo zonke izifunda kanye namazinga.
Ukusetshenziswa okuhlangene kobuchwepheshe be-ACL, okuhlanganisa i-Basic ACL, i-MAC-based ACL, i-IP-based ACL, i-Time-based ACL, kanye ne-VLAN-based ACL, kwakha uhlelo lokuphepha olucwengekile nolunamandla olunezinhlangothi ezintathu kanye nokulawula ithrafikhi lwesistimu yokubonisa kusukela ezilinganisweni eziningi njengesikhathi, isikhala (i-VLAN), isiqondiso, kanye nomkhawulokudonsa.
Ngokuncika ohlelweni olujulile lokuzivikela oluqukethe ukuqinisekiswa okuthembekile kwe-firmware, ukulawulwa kokufinyelela okuhlakaniphile, kanye nokuphathwa kwenqubomgomo enamandla, ubuqotho nokuthembeka kohlelo kuqinisekisiwe ngokuphelele.
Ekuthuthukisweni okuqhubekayo kanye nokuguquka kwezinhlelo zokubonisana zokuhamba ngesitimela,UBelden HirschmannIzixazululo zenethiwekhi yezimboni zobungcweti sezibe yitshe lesisekelo elithembekile lokwakhiwa kwedijithali embonini. Izixazululo zethu zisetshenziswe kumaphrojekthi esistimu yokusayina yesitimela esingaphansi komhlaba angaphezu kuka-120 ezweni lonke; le mikhuba ebanzi isenze saqonda ngokujulile. Ukuqhubekela phambili ngokungaphezi, uBelden Hirschmann uyaqhubeka nokuzinikela ekwakheni uhlelo lwezinzwa oluthembekile embonini yezokuthutha yesitimela ngokusebenzisa ubuchwepheshe obusha bokuxhumana, eqhuba njalo intuthuko ekushayeleni ukuphepha nokusebenza kahle, kanye nokuqinisekisa ukuhamba kahle kwezokuthutha zasemadolobheni.
