Uhlolojikelele Lomkhiqizo Othenjwayo we-TMR

I-Trusted® Processor iyingxenye yokucubungula eyinhloko Kusistimu Ethembekile. Kuyimojula enamandla, elungiseka umsebenzisi ehlinzeka ngezinsiza zokulawula nokuqapha kohlelo lonke futhi icubungule idatha yokufaka nokuphumayo etholwe ezinhlobonhlobo zamamojula we-analogue nawedijithali Okokufaka / Okuphumayo (I/O) kulo lonke Ibhasi Le-Trusted TMR Inter-Module Communications. Ibanga lezinhlelo zokusebenza ze-Trusted TMR Processor liyahlukahluka ngezinga lobuqotho futhi lihlanganisa ukulawula umlilo negesi, ukuvala shaqa kwesimo esiphuthumayo, ukuqapha nokulawula, nokulawula i-turbine.

Izici:

• I-Triple Modular Redundant (TMR), umsebenzi wokubekezelela amaphutha (3-2-0). • I-Hardware Implemented Fault Tolerant (HIFT) yezakhiwo. • Izingxenyekazi zekhompuyutha ezizinikele kanye nezinhlelo zesofthiwe zokuhlola ezihlinzeka ngokubonwa kwamaphutha ngokushesha kanye nezikhathi zokuphendula. • Ukuphatha iphutha okuzenzakalelayo ngaphandle kokuphazamiseka okwesabisayo. • Isazi-mlando samaphutha esinesikhathi. • Ukushintshwa okushisayo (asikho isidingo sokulayisha kabusha izinhlelo). • Uhlelo olugcwele lwezilimi zokuhlela ze-IEC 61131-3. • Izinkomba zephaneli yangaphambili ezibonisa impilo nesimo semojuli. • Iphaneli yangaphambili ye-RS232 imbobo yokuxilongwa kwe-serial yokuqapha uhlelo, ukumisa nokuhlela. • I-IRIG-B002 kanye namasiginali wokuvumelanisa wesikhathi esingu-122 (atholakala ku-T8110B kuphela). • Iphutha leprosesa elisebenzayo nelibekwe eceleni kanye nokwehluleka koxhumana nabo. • Izixhumanisi ezimbili ze-RS422 / 485 ezilungisekayo ezi-2 noma ezi-4 (zitholakala ku-T8110B kuphela). • Uxhumano lwezintambo olulodwa lwe-RS485 2 (lutholakala ku-T8110B kuphela). • I-TϋV Certified IEC 61508 SIL 3.

1.1. Uhlolojikelele

I-Trusted TMR Processor iwumklamo obekezelela iphutha osuselwe esakhiweni se-Triple Modular Redundant (TMR) esisebenza ekucushweni kwesinyathelo sokukhiya. Umfanekiso 1 ubonisa, ngamagama enziwe lula, ukwakheka okuyisisekelo kwemojula ye-Trusted TMR Processor. Imojula iqukethe izifunda ezintathu zokuqukatha iphutha leProsesa (i-FCR), ngayinye equkethe i-Motorola Power PC series Processor kanye nenkumbulo yayo ehlotshaniswa nayo (EPROM, DRAM, Flash ROM, ne-NVRAM), inkumbulo efakwe kumephu ye-I/O, i-voter kanye ne-glue logic circuits. Iphrosesa ngayinye i-FCR ivotele ukufinyelela kokufunda okubili kokuthathu (2oo3) kwezinye izinhlelo ezimbili zememori ye-FCR yeProsesa ukuze kuqedwe ukusebenza okuhlukene. Amaphrosesa amathathu emojuli agcina futhi asebenzise uhlelo lohlelo, askene futhi abuyekeze amamojula e-I/O futhi abone amaphutha esistimu. Iphrosesa ngayinye yenza uhlelo lohlelo ngokuzimela, kodwa ngokuvumelanisa isinyathelo sokukhiya nezinye ezimbili. Uma kwenzeka enye Iphrosesa ihluka, izindlela ezengeziwe zivumela Iphrosesa ehlulekile ukuthi iphinde ivumelanise nezinye ezimbili. Iphrosesa ngayinye inesixhumi esibonakalayo esihlanganisa umvoti ofakayo, ingqondo yesitholi sokungafani, inkumbulo, kanye nesixhumi esibonakalayo sebhasi eliphumayo eliya ku-Inter-Module Bus. Okukhiphayo kweProsesa ngayinye kuxhunywe yisixhumi semojula esiteshini esihlukile sebhasi le-Inter-Module eliphindwe kathathu.

3. Isicelo

3.1. Ukucushwa Kwemojuli Iphrosesa ye-TMR Ethembekile ayidingi ukucushwa kwehadiwe. Yonke Isistimu Ethembekile idinga ifayela lokumisa le-System.INI. Imininingwane yokuklama lokhu inikezwe ku-PD-T8082 (I-Trusted Toolset Suite). Ukucushwa kunoMprosesa onikezwe indawo engakwesokunxele ye-chassis Yephrosesa ngokuzenzakalelayo. I-System Configurator ivumela ukukhethwa kokukhethwa kukho kumachweba, i-IRIG nemisebenzi yesistimu. Ukusetshenziswa kwe-System Configurator kuchazwe ku-PD-T8082. Izinketho zichazwe ngezansi.

3.1.1. Isigaba Sokuvuselela Uma Kukhethwa Okuguquguqukayo Kwenethiwekhi Yokuvikela Ngokuzenzakalelayo, lokhu kulungiselela Uhlelo Oluthembekile ukuthi lusebenzise imephu ye-Modbus Protocol encishisiwe. Bona incazelo yomkhiqizo PD-8151B (Imojuli Yesixhumi Esibonakalayo Esithenjwayo) ukuze uthole imininingwane eyengeziwe. I-Inter Group Ukubambezeleka kulingana nomjikelezo wokubuyekeza we-Modbus. Lesi isikhathi esincane phakathi kwemilayezo yokubuyekeza ye-Modbus elandelanayo ethunyelwa ku-Communications Interface Modules ngayinye. Inani elizenzakalelayo (njengoba libonisiwe) lingu-50 ms okunikeza ukuvumelana phakathi kokubambezeleka nokusebenza. Ukulungiswa kwenziwa ngo-32 integer ms increments, okusho ukuthi inani lika-33 lizolingana no-64 ms njengoba lizokwenza 64. Lokhu kungase kukhushulwe noma kwehliswe njengoba kudingekile, nokho njengoba kuthunyelwa umlayezo owodwa wokubuyekeza ngokuskena kwesicelo ngasinye, futhi ukuskena kohlelo lokusebenza kungase kuvame ukwenziwa. ngaphezu kuka-50 ms, kunenzuzo encane ekulungiseni lokhu okuguquguqukayo.

3.1.2. Isigaba Sokuphepha Lesi sibonisi esingenhla siphinde sisetshenziselwe ukulungisa igama-mfihlo elivumela umsebenzisi ukuthi aphenye Uhlelo Oluthembekile esebenzisa i-Windows-based HyperTerminal facility noma uhlelo olufanayo lwetheminali. Iphasiwedi ilungiswa ngokukhetha inkinobho Yephasiwedi Entsha bese ufaka iphasiwedi entsha kabili ebhokisini lengxoxo elibonisiwe.

3.1.3. Isigaba Se-ICS2000 Lesi sigaba sisebenza kuphela Kuzinhlelo Ezithenjwayo ezixhunywe Nge-Trusted to ICS2000 Interface Adapter ohlelweni lwe-ICS2000. Lokhu kuvumela imithombo yedatha yamathebula okulingisa amathathu ukuthi akhethwe. Sicela ubheke umphakeli wakho Othenjwayo ukuze uthole ulwazi olwengeziwe.
