Ezimbonini zezinqubo ezinzima, lapho ihora elilodwa lokukhiqiza okumisiwe lingabangela izindleko ezingaphezu kuka-$100,000, ikhono lokulandelela iphutha lenethiwekhi liye ekuqhekekeni kwechweba noma ikhebula ngemizuzwana kunokuba amahora ashintshe ngokuphelele indlela yokulungisa. Izinqubo zokuxilonga ezithuthukisiwe ezihlanganiswe ohlelweni lokuxhumana zinikeza ukunemba okuqondile mayelana nempilo yenethiwekhi, zinciphisa ukubambezeleka kokuxazulula izinkinga futhi zikhulise isikhathi sokusebenza.
Kungani ukusebenzisana, ukuzimisela, kanye nokuphepha kwe-cyber kubalulekile
Umehluko oyinhloko wesistimu yokuxhumana yezimboni yi-determinism—isiqinisekiso esiphelele sokuthi umlayezo uzodluliselwa futhi wamukelwe ngesikhathi esiqondile nesibikezelwayo. Ezinhlelweni zokulawula ukunyakaza, njengezingalo zerobhothi ezivumelanisiwe noma imigqa yokupakisha enesivinini esikhulu, i-network jitter kumele igcinwe ngaphansi kwe-microsecond eyodwa ngokuqinile. Ngaphandle kwalokhu kunemba okuqinisekile, ukuhlanganiswa kwe-multi-axis kwehluleka, okuholela ekuphazamisekeni komkhiqizo kanye nokushayisana kwemishini.
Ukusebenzisana kuqinisekisa ukuthi imishini ehlukene evela kubathengisi abahlukahlukene ingakwazi ukuxhumana ngaphandle kwezithiyo ezizimele. Izinqubo ezijwayelekile zivumela izikhungo ukuthi zihlanganise imishini ekhethekile kunethiwekhi ehlangene yesitshalo sonke, kunciphisa izindleko zokukhiya nokuhlanganisa abathengisi. Kodwa-ke, lokhu kuxhumana okwandisiwe kwandisa indawo yokuhlasela. Ukusebenzisa izinyathelo zokuphepha kwe-cyber eziqinile, ikakhulukazi ukunamathela kumazinga e-IEC 62443, akusadingeki. Izinhlelo zokuxhumana zezimboni kumele zifake ukuhlolwa okujulile kwephakethe, ukuhlukaniswa kwenethiwekhi, kanye nokulawulwa kokufinyelela ezingeni le-port ukuvikela kokubili izinsongo ze-cyber zangaphandle kanye nokungalungiselelwa kahle kwangaphakathi.
Lokho Okufakwa Yisistimu Yokuxhumana Yezimboni
Ukwakheka kohlelo lokuxhumana lwezimboni kuhlanganisa izendlalelo eziningi, kuhlanganisa kalula ihadiwe ebonakalayo nezinqubo zesofthiwe eziyinkimbinkimbi. Ngokuhambisana eduze ne-Purdue Enterprise Reference Architecture, lezi zinhlelo zihlukanisa ithrafikhi yenethiwekhi kusukela ku-Level 0 (izinqubo ezibonakalayo) kuze kufike ku-Level 3 (izinhlelo zokusebenza zokukhiqiza) nangaphezulu. Le ndlela ehlanganisiwe iqinisekisa ukuthi idatha yokulawula ebalulekile ihlala ihlukanisiwe nethrafikhi yebhizinisi engazweli kakhulu ngesikhathi.
Izendlalelo eziyinhloko kanye nezingxenye
Ezingeni eliyisisekelo, izingxenye zomzimba zifaka phakathi amaswishi aqinile, ama-router, amasango, kanye nezintambo eziklanyelwe ukumelana namazinga okushisa aphezulu, ukuphazamiseka okukhulu kwe-electromagnetic (EMI), kanye nokudlidliza okuqhubekayo. Amaswishi e-Industrial Ethernet, isibonelo, avame ukuba nezindawo zokuvala ezilinganiselwe yi-IP67, i-conformal coating kumabhodi wesekethe, kanye nokufakwa kwamandla okungafuneki ukuze kuphile ezimweni ezinzima zephansi lesitshalo.
Ngaphezulu kwesendlalelo esibonakalayo, isixhumanisi sedatha kanye nezendlalelo zohlelo lokusebenza zisebenzisaizinqubo ezikhethekile zezimboniukuphatha ithrafikhi. Amadivayisi e-Gateways kanye nama-edge computing asebenza njengabahumushi, eguqula idatha ye-serial yakudala ibe amaphakethe e-Ethernet anamuhla. Lokhu kuvumela imishini emidala, ehlukanisiwe ukuthi ihlanganyele kumasu okuqoqwa kwedatha athuthukile ngaphandle kokudinga ukulungiswa okuphelele kwehadiwe.
Indlela amaphrothokholi, abezindaba, i-topology, kanye nokwakheka kwesimo sesikhathi
Ukukhethwa kwemidiya ebonakalayo kunquma kakhulu amakhono enethiwekhi kanye nemikhawulo. Izintambo zethusi ezijwayelekile zezimboni (i-Cat5e noma i-Cat6a shielded twisted pair) zitholakala yonke indawo kodwa zihlala ziboshwe umkhawulo oqinile wamamitha ayi-100 ubude ngesigaba ngasinye. Ezindaweni ezinkulu noma ezindaweni ezine-EMI enzima, izintambo ze-fiber optic zemodi eyodwa ziyasetshenziswa, ezikwazi ukudlulisa idatha emabangeni angaphezu kwamakhilomitha ayi-10 ngaphandle kokuwohloka kwesiginali.
Umklamo we-Topology ubuye wakhe ukuqina kwesistimu. Ngenkathi i-IT yebhizinisi ivame ukuthembela ku-topology yezinkanyezi, amanethiwekhi ezimboni avame ukusebenzisa ukucushwa kwendandatho noma kwe-daisy-chain ukuze kuthuthukiswe ukusebenza kwezintambo futhi kuqinisekiswe ukungasebenzi kahle. Amaphrothokholi afana ne-Media Redundancy Protocol (MRP) noma i-Device Level Ring (DLR) avumela i-topology yendandatho ukuthi ilulame ekuqhekekeni kwekhebula ngaphansi kwama-millisecond angu-50. Ngaphezu kwalokho, isikhathi esinembile siphoqelelwa nge-IEEE 1588 Precision Time Protocol (PTP), evumelanisa amawashi edivayisi kunethiwekhi yonke ukuze kube nokunemba kwe-sub-microsecond, okuyisidingo sokulawula ukunyakaza okuhlelekile kakhulu.

Amazinga ethangi lokuqapha isitshalo esisebenzisa inqubo ezenzakalelayo angadinga kuphela izikhathi zomjikelezo emakhulwini ama-millisecond, okwenza ukuxhumana okujwayelekile kwe-TCP/IP kwanele. Ngakolunye uhlangothi, umshini wokunyathelisa osheshayo udinga izikhathi zomjikelezo ngaphansi kwe-millisecond eyi-1.
Esinye isici esibalulekile ukusebenza kahle kweprothokholi yokulayisha umthwalo. Amanye amaphrothokholi anezindleko ezinkulu zokuqondisa kanye nokuxilonga, okwamukelekayo kumanethiwekhi amakhulu e-SCADA kodwa okulimaza ukulawulwa kwezinga lomshini okunqunyiwe kakhulu. Ukukhetha iphrothokholi nakho kuthinta kakhulu izindleko zehadiwe, njengoba amanye amazinga okusebenza okuphezulu adinga ama-Application-Specific Integrated Circuits (ASICs) akhethekile noma ama-Field-Programmable Gate Arrays (FPGAs) ngaphakathi kwedivayisi ngayinye yasensimini.
I-Industrial Ethernet vs i-fieldbus
Ukwakhiwa kwe-fieldbus yakudala, njenge-PROFIBUS DP noma i-Modbus RTU, kusebenza ekuxhumaneni okulandelanayo (isb., i-RS-485). Lawa manethiwekhi aqinile kakhulu futhi aqinisekile kodwa ahlushwa ukulinganiselwa okukhulu kwe-bandwidth, ngokuvamile afinyelela ku-12 Mbps ye-PROFIBUS futhi aphansi kakhulu kwamanye. Anezinga eliphezulu futhi alwela ukuphatha inani elikhulu ledatha yokuxilonga edingekayo ezinhlelweni zokulungisa izibikezelo zanamuhla.
Izinqubo ze-Industrial Ethernet, okuhlanganisa i-PROFINET, i-EtherNet/IP, kanye ne-EtherCAT, zithathe indawo ye-fieldbus kakhulu ekusetshenzisweni okusha. Isebenza ku-100 Mbps kuya ku-1 Gbps, i-Industrial Ethernet inikeza i-bandwidth edingekayo ukuze kudluliselwe idatha yokulawula yesikhathi sangempela kanye nedatha yokuxilonga engeyona yesikhathi sangempela ngentambo efanayo ebonakalayo. Ngenkathi amanethiwekhi e-fieldbus evame ukukhawulelwa kuma-node angu-32 noma angu-128 ngengxenye ngayinye, amanethiwekhi e-Industrial Ethernet angakhula ngokwengqondo abe yizinkulungwane zamadivayisi axhunyiwe, uma nje inethiwekhi ihlukaniswe kahle.
Ukushintshana kokulibaziseka, ukuguquguquka, kanye nokuqina
Ukufinyelela ukubambezeleka okuphansi kakhulu kuvame ukudinga ukuguquguquka ekuvumelaneni kwenethiwekhi okujwayelekile. Isibonelo, i-EtherCAT ifinyelela izikhathi zomjikelezo ezingaphansi kwama-microsecond ayi-100 kuma-I/O amaphuzu ayi-1,000 asatshalaliswa ngokusebenzisa indlela "yokucubungula ngokushesha". Kodwa-ke, lokhu kudinga ihadiwe ekhethekile kuma-slave node futhi akusebenzisi ukushintshana kwe-Ethernet okujwayelekile ngaphakathi kwesigaba se-EtherCAT.
Ngakolunye uhlangothi, amaphrothokholi afana ne-EtherNet/IP athembele ngokuphelele kuhadiwe ye-Ethernet ejwayelekile, engashintshiwe kanye ne-TCP/UDP/IP suite. Lokhu kukhulisa ukusabalala kanye nokuhlanganiswa kwe-IT/OT okungenamthungo kodwa kwenza ukufeza ukunqunywa kwe-sub-millisecond kuncike kakhulu ekucushweni kwenethiwekhi okucophelelayo, ukubekwa phambili kwe-Quality of Service (QoS), kanye nokushintsha okuphethwe okuphezulu.
| Iphrothokholi | Ubuchwepheshe Obuyisisekelo | Isikhathi Esijwayelekile Somjikelezo | Isidingo Sehadiwe | Icala Lokusetshenziswa Okuyinhloko |
|---|---|---|---|---|
