Belden HirschmannMa network a mafakitale amapereka maziko odalirika kwambiri, otsika, komanso osinthika pazachilengedwe a machitidwe olumikizirana a sitima, kuthandizira kusintha kwa machitidwe osuntha monga CBTC ndi TACS. Kugwira ntchito ndi chitetezo nthawi yeniyeni kumatsimikiziridwa kudzera mu hardware redundancy, ma protocol osinthira mwachangu (monga MRP/PRP/HSR), nthawi yolumikizirana (PTP/TSN), ndi multi-layer logical isolation (VLAN/ACL). Ali ndi mphamvu zolekerera zachilengedwe kuphatikiza kutentha kwakukulu, kukana fumbi ndi dzimbiri, komanso kugwirizanitsa ma electromagnetic, kuthandizira kukulitsa modular, kuzindikira kutali, ndi kufufuza komwe kungatsatidwe. Amagwiritsidwa ntchito m'mapulojekiti opitilira 120 a sitima yapansi panthaka, amapereka "dongosolo lamanjenje" lokhazikika komanso losinthika la subsystem yolumikizirana, kuonetsetsa kuti chitetezo ndi magwiridwe antchito zikugwira ntchito bwino.
Pakugwiritsa ntchito ma netiweki a ma signaling system mumakampani oyendera sitima ku China, mayankho nthawi zonse amakumana ndi mavuto ambiri okhudzana ndi "chitetezo ndi magwiridwe antchito":
Malo ovuta a thupi ndi ma elekitiromagineti: Malo okhazikitsira sitima ndi ovuta komanso osiyanasiyana. Ma netiweki a mafakitale amatha kupirira kugwedezeka kosalekeza, fumbi, chinyezi, komanso kusintha kwakukulu kwa kutentha pakati pa malo amkati ndi akunja, kuonetsetsa kuti zizindikiro zomveka bwino komanso zokhazikika ngakhale atasokonezedwa kwambiri ndi ma elekitiromagineti.
Kudalirika ndi Kupezeka: Kudzera mu kapangidwe kowonjezera pa zigawo zakuthupi ndi za netiweki, mfundo imodzi yolephera imachotsedwa pa hardware kupita ku mulingo wowonjezera wa protocol, zomwe zimapereka chitsimikizo cholumikizirana chosasokoneza cha makina olumikizirana.
Kutha Kulankhulana Pa Nthawi Yeniyeni: Pa ntchito zofunika kwambiri monga Automatic Train Protection (ATPB), kuchedwa kuyenera kudziwikiratu mpaka mulingo wa millisecond kapena microsecond. Netiweki iyenera kukhala ndi kuchedwa kochepa kuti iwonetsetse kuti malamulo owongolera aperekedwa mkati mwa nthawi yomwe yatchulidwa.
Pulatifomu Yolumikizirana Yogwirizana ndi Yogwirizana: Makina olumikizirana amakono a CBTC (Computer-Assisted Train Control) ogwiritsira ntchito kulumikizana apangitsa kuti pakhale kufunikira kwa netiweki yogwirizana. Netiwekiyo iyenera kuonetsetsa kuti deta ya bizinesi yagawidwa bwino pakati pa ma subsystem osiyanasiyana, kuonetsetsa kuti deta yayikulu ikupezeka komanso ikupezeka mosavuta, komanso kupangitsa kuti kapangidwe kake kakhale kosavuta komanso kogwira ntchito bwino.
Belden Hirschmann Industrial Network ndi Signaling System Adaptation
Kutsimikizira Konse za Kulekerera Kwachilengedwe
Yokhoza kugwira ntchito pa kutentha kwakukulu (monga -40℃ mpaka +70℃), yokhala ndi kapangidwe kophimba kuti isanyowe ndi dzimbiri.
Chitetezo cha Mankhwala ndi Fumbi: Chitetezo chapamwamba cha IP65/67 kuti chigwiritsidwe ntchito panja, kuteteza kulowerera kwa fumbi ndi dzimbiri kuchokera ku mpweya woipa.
Kudalirika kwa nthawi yayitali: Kutengera kapangidwe ka MTBF kapamwamba, nthawi yapakati pakati pa kulephera (MTBF) imapitirira zaka 25, ndipo ma module ena amapitirira zaka 100.
Kukhazikika kwa magetsi: Kuli ndi kugwirizana kwapamwamba kwa ma elekitiromagineti komanso kapangidwe ka magetsi kodzipatula, kuonetsetsa kuti chizindikirocho chili bwino pakasokonezedwa.
Kudalirika kwakukulu ndi kupezeka kwake:
Kumbali ya zida zamagetsi, zinthu za Belden zapamwamba kwambiri zimakhala ndi magetsi osafunikira komanso mapangidwe a ma module osafunikira.
Kumbali ya mapulogalamu, Belden imapereka ukadaulo wosiyanasiyana wowonjezera mphamvu kuti zitsimikizire kudalirika kwa netiweki yonse, monga IEC 62439 standard Industrial Ring Redundancy Protocol (MRP) ndi ukadaulo wolumikizira ma netiweki awiri owonjezera mphamvu, zomwe zimapangitsa kuti netiweki isinthe pang'onopang'ono mkati mwa 50ms.
Imathandizira ma module osinthika modular, kuzindikira kutali, komanso kukonza zinthu moganizira zomwe zikuchitika, zomwe zimachepetsa kwambiri nthawi yokonzanso (MTBF).
Kutumiza deta nthawi yeniyeni pogwiritsa ntchito kuchedwa kochepa, komanso nthawi yeniyeni yofulumira:
Mayankho achikhalidwe amagwiritsa ntchito ma protocol ogwirizanitsa nthawi monga SNTP, NTP, ndi IEEE 1588 PTP kuti apereke chitsimikizo cha kulumikizana kwa millisecond, microsecond, kapena nanosecond-level deterministic kwa Ethernet.
Zogulitsa zama netiweki zamafakitale zomwe zimathandiza ukadaulo wa TSN zimaonetsetsa kuti malamulo owongolera sitima ndi zilolezo zoyendera zimaperekedwa mkati mwa nthawi yokhwima.
Ma protocol olumikizirana osasinthika monga PRP/HSR amapereka njira zolumikizirana zosasokoneza za kulumikizana kwa m'mbali mwa msewu ndi machitidwe olumikizana.
Kapangidwe ka kulankhulana kodzipereka kokhazikika komanso kodziteteza:
Imaphimba ma LAN osiyanasiyana a Layer 2, kuphatikiza ma VLAN wamba, ma VLAN okhala ndi ma port, ma VLAN okhala ndi protocol, ma VLAN a mawu, ma VLAN okhala ndi ma subnet a MAC/IP, ndi ma VLAN achinsinsi, zomwe zimakwaniritsa zofunikira zodzipatula za mautumiki osiyanasiyana mkati mwa mzere.
Kuphunzira njira zoyendetsera zinthu za Layer 3 monga RIP v1/v2, OSPF v2, static routing, ndi PIM-DM/SM/SSM kumapereka chithandizo chachikulu pakulankhulana kodalirika komanso kogwira mtima m'madera ndi m'magawo osiyanasiyana.
Kugwiritsa ntchito ukadaulo wa ACL pamodzi, kuphatikizapo Basic ACL, MAC-based ACL, IP-based ACL, Time-based ACL, ndi VLAN-based ACL, kumamanga njira yowongolera chitetezo cha magawo atatu komanso yowongolera magalimoto yamakina olumikizirana kuchokera kumitundu yosiyanasiyana monga nthawi, malo (VLAN), njira, ndi bandwidth.
Podalira njira yodzitetezera yokhazikika yomwe ili ndi kutsimikizira kodalirika kwa firmware, kuwongolera mwayi wolowera mwanzeru, komanso kasamalidwe ka mfundo zosinthika, umphumphu ndi kudalirika kwa dongosololi ndizotsimikizika mokwanira.
Mu kukonzanso kosalekeza ndi kusintha kwa machitidwe operekera zizindikiro za mayendedwe a sitima,Belden HirschmannMayankho aukadaulo a maukonde a mafakitale akhala maziko odalirika pakupanga ma digito amakampaniwa. Mayankho athu agwiritsidwa ntchito pamapulojekiti opitilira 120 a sitima zapamtunda padziko lonse lapansi; machitidwe akuluakulu awa atipangitsa kumvetsetsa bwino. Popita patsogolo, Belden Hirschmann akupitilizabe kudzipereka popanga makina odalirika amitsempha yamagalimoto a sitima kudzera muukadaulo watsopano wolumikizirana, kupitilizabe kuwongolera chitetezo ndi magwiridwe antchito, ndikuwonetsetsa kuti mayendedwe akumatauni akuyenda bwino.
