UBelden HirschmannIinethiwekhi zoshishino zibonelela ngesiseko sonxibelelwano esithembekileyo kakhulu, esiphantsi kwexesha, nesilungelelaniswe nokusingqongileyo kwiinkqubo zokubonisana zezithuthi zikaloliwe, zixhasa uphuhliso lweenkqubo zeebhloko ezihambayo ezifana ne-CBTC kunye ne-TACS. Ukusebenza kunye nokhuseleko ngexesha langempela kuqinisekiswa ngokuphindaphindwa kwezixhobo, iiprotokholi zokutshintsha ngokukhawuleza (ezifana ne-MRP/PRP/HSR), ukuvumelanisa ixesha (PTP/TSN), kunye nokwahlulwa okune-layer logical (VLAN/ACL). Zinezakhono zokunyamezelana nokusingqongileyo kubandakanya uluhlu olubanzi lobushushu, ukumelana nothuli kunye nokugqwala, kunye nokuhambelana kwe-electromagnetic, ukuxhasa ukwanda kwemodyuli, ukuxilongwa okukude, kunye nokuhlolwa okulandelekayo. Zisetyenziswe kwiiprojekthi zesitimela esingaphantsi komhlaba ezingaphezu kwe-120, zibonelela "ngenkqubo yeemvakalelo" ezinzileyo neyonganyelwayo kwinkqubo engaphantsi kwesignali, ukuqinisekisa ukhuseleko lokusebenza kunye nokusebenza kakuhle.
Ekusetyenzisweni kwenethiwekhi yeenkqubo zokubonisa kwishishini lezothutho lukaloliwe eTshayina, izisombululo zihlala zijongene nemingeni emininzi enxulumene "nokhuseleko nokusebenza kakuhle":
Iindawo ezinobungozi zomzimba neze-electromagnetic: Indawo yokufakela uthutho lwesitimela iyinkimbinkimbi kwaye iyaguquguquka. Iinethiwekhi zoshishino zinokumelana nokungcangcazela okuqhubekayo, uthuli, ukufuma, kunye nokutshintshatshintsha kobushushu phakathi kweendawo zangaphakathi nezangaphandle, ukuqinisekisa imiqondiso ecacileyo nezinzileyo nokuba iphantsi kokuphazamiseka okukhulu kwe-electromagnetic.
Ukuthembeka kunye nokuFumaneka: Ngokusebenzisa uyilo olungafunekiyo kwiileya ezibonakalayo nezenethiwekhi, amanqaku okusilela asuswa kwi-hardware ukuya kwinqanaba le-protocol elingafunekiyo, nto leyo enika isiqinisekiso sonxibelelwano esingaphazanyiswayo kwinkqubo yokubonisa.
Ubuchule boNxibelelwano lweXesha langempela: Kwimisebenzi ebalulekileyo efana noKhuseleko loQeqesho oluZenzekelayo (i-ATPB), ukubambezeleka kufuneka kuqikelelwe ukuya kwinqanaba le-millisecond okanye kwinqanaba le-microsecond. Inethiwekhi kufuneka ifikelele kwi-latency ephantsi ukuqinisekisa ukuba imiyalelo yokulawula ihanjiswa ngaphakathi kwexesha elichaziweyo.
Iqonga loNxibelelwano oluManyeneyo noluHlangeneyo: Iinkqubo zokubonisana ze-CBTC (Computer-Assisted Train Control) ezisekelwe kunxibelelwano lwanamhlanje zidale imfuno yenethiwekhi emanyeneyo. Inethiwekhi kufuneka iqinisekise ukuba ihlukaniswe ngokukhuselekileyo ngelixa ithwala ukuhanjiswa kwedatha yeshishini phakathi kweenkqubo ezahlukeneyo, iqinisekisa ukufumaneka kunye nokufikeleleka kwedatha ephambili, ilula uyilo ngelixa igcina ukusebenza kakuhle.
I-Belden Hirschmann Inethiwekhi yezoShishino kunye neNkqubo yokuSayina i-Adaptation
Ukuqinisekiswa Okupheleleyo Kokunyamezelana Kwendalo
Iyakwazi ukusebenza kumanqanaba obushushu abanzi (umz., -40℃ ukuya ku +70℃), kunye noyilo lwengubo yokukhusela ukufuma kunye nokumelana nokugqwala.
Ukhuseleko lweeKhemikhali noThuli: Ukhuseleko oluphezulu lwe-IP65/67 lokusetyenziswa ngaphandle, oluthintela ukungena kothuli kunye nokugqwala okuvela kwiigesi eziyingozi.
Ukuthembeka kwexesha elide: Ngokusekelwe kuyilo oluphezulu lwe-MTBF, ixesha eliphakathi phakathi kokusilela (i-MTBF) lidlula iminyaka engama-25, kwaye ezinye iimodyuli zidlula iminyaka eli-100.
Uzinzo lombane: Luneempawu zokuhambelana kwe-electromagnetic kunye noyilo lokwahlulwa kombane, oluqinisekisa ukuthembeka kwesignali phantsi kokuphazamiseka.
Ukuthembeka okuphezulu kunye nokufumaneka:
Kwicala lezixhobo zekhompyutha, iimveliso zikaBelden ezikumgangatho wezoshishino zinombane ongafunekiyo kunye noyilo lweemodyuli ezingafunekiyo.
Kwicala lesoftware, iBelden ibonelela ngeetekhnoloji ezahlukeneyo zokuphinda kusetyenziswe izixhobo ukuqinisekisa ukuthembeka kwenethiwekhi yonke, njenge-IEC 62439 standard Industrial Ring Redundancy Protocol (MRP) kunye netekhnoloji yokudibanisa inethiwekhi yeringi ezimbini, nto leyo efezekisa utshintsho lwe-network redundancy ngaphakathi kwe-50ms.
Ixhasa iimodyuli ezitshintshatshintshayo ezishushu, ukuxilongwa okukude, kunye nokugcinwa kwangaphambili, okunciphisa kakhulu ixesha eliphakathi lokulungisa (MTBF).
Udluliselo lwedatha oluphantsi, olune-jitter yexesha langempela:
Izisombululo eziqhelekileyo zisebenzisa iiprotokholi zokuvumelanisa ixesha ezifana ne-SNTP, i-NTP, kunye ne-IEEE 1588 PTP ukubonelela ngeziqinisekiso zonxibelelwano oluqinisekileyo lwe-millisecond, i-microsecond, okanye ne-nanosecond-level kwi-Ethernet.
Iimveliso zenethiwekhi ezikumgangatho wezoshishino ezixhasa itekhnoloji ye-TSN ziqinisekisa ukuhanjiswa kwemiyalelo yolawulo lwesitimela kunye nezigunyaziso zokuhamba ngaphakathi kwexesha elimiselweyo.
Iiprotokholi zonxibelelwano ezingafunekiyo ezifana ne-PRP/HSR zibonelela ngeendlela zonxibelelwano ezingaphazanyiswayo zonxibelelwano olusecaleni kwendlela kunye neenkqubo ezidibanisayo.
Uyilo lonxibelelwano olusekelwe kwingqiqo, oluneenkcukacha zokuzikhusela:
Igubungela ii-LAN ezahlukeneyo zeLayer 2 virtual, kuquka ii-VLAN eziqhelekileyo, ii-VLAN ezisekwe kwizibuko, ii-VLAN ezisekwe kwiprotocol, ii-VLAN zelizwi, ii-VLAN ezisekwe kwi-subnet ye-MAC/IP, kunye nee-VLAN zabucala, ukuhlangabezana neemfuno zokwahlulwa ngokwengqiqo kweenkonzo ezahlukeneyo ngaphakathi kwendawo yomgca.
Ukugubungela iiprotokholi zendlela zeLayer 3 ezifana ne-RIP v1/v2, i-OSPF v2, i-static routing, kunye ne-PIM-DM/SM/SSM kubonelela ngenkxaso ephambili yonxibelelwano oluthembekileyo nolusebenzayo kuzo zonke iingingqi kunye namanqanaba.
Ukusetyenziswa okudibeneyo kwezobuchwepheshe be-ACL, kuquka i-Basic ACL, i-MAC-based ACL, i-IP-based ACL, i-Time-based ACL, kunye ne-VLAN-based ACL, kwakha inkqubo yokhuseleko olunemilinganiselo emithathu kunye nolawulo lwethrafikhi ephucukileyo neguquguqukayo yenkqubo yokubonisa ukusuka kwiimilinganiselo ezahlukeneyo ezifana nexesha, indawo (VLAN), ulwalathiso, kunye ne-bandwidth.
Ngokuxhomekeke kwinkqubo yokuzikhusela enzulu equka ukuqinisekiswa okuthembekileyo kwe-firmware, ulawulo lokufikelela olukrelekrele, kunye nolawulo lwemigaqo-nkqubo eguqukayo, ukuthembeka kunye nokuthembeka kwenkqubo kuqinisekiswa ngokupheleleyo.
Ekuphuculeni okuqhubekayo kunye nophuhliso lweenkqubo zokuhambisa imiqondiso yoololiwe,UBelden HirschmannIzisombululo zobungcali zenethiwekhi yemizi-mveliso ziye zaba lilitye elibalulekileyo lokwakha ngedijithali kushishino. Izisombululo zethu zisetyenziswe kwiiprojekthi zenkqubo yokubonisana yesitimela esingaphantsi komhlaba ezingaphezu kwe-120 kuzwelonke; ezi ndlela zibanzi ziye zakha ukuqonda kwethu okunzulu. Ukuqhubela phambili ngokungapheliyo, uBelden Hirschmann uyaqhubeka nokuzinikela ekwakheni inkqubo yemithambo-luvo ethembekileyo kushishino lwezithuthi zikaloliwe ngokusebenzisa ubuchwepheshe obutsha bokunxibelelana, eqhuba ngokuqhubekayo uphuculo ekuqhubeni ukhuseleko kunye nokusebenza kakuhle, kunye nokuqinisekisa ukuhamba kakuhle kwezothutho zasezidolophini.
