1.1.Isishwankathelo

I-Trusted TMR Processor luyilo olunyamezelayo olusekwe kwi-Triple Modular Redundant (TMR) yoyilo olusebenza kwi-lock-step configuration.Umzobo we-1 ubonisa, ngokwemigaqo elula, isakhiwo esisisiseko se-Trusted TMR Processor module.Imodyuli iqulethe imimandla emithathu ye-Processor fault containment (FCR), nganye iqulethe i-Motorola Power PC series Processor kunye nememori ehambelana nayo (EPROM, i-DRAM, i-Flash ROM, kunye ne-NVRAM), i-memory mapped I / O, umvoti kunye neesekethe ze-glue logic.I-Processor FCR nganye ivotele i-2-out-three (2oo3) ukufikelela kokufunda kwezinye iinkqubo ezimbini zeememori ze-FCR zeProsesa ukuphelisa ukusebenza okungafaniyo.Iiprosesa ezintathu zemodyuli zigcina kwaye ziphumeze inkqubo yesicelo, ziskena kwaye zihlaziye iimodyuli ze-I/O kwaye zibone iimpazamo zesistim.Umprosesa ngamnye uphumeza inkqubo yesicelo ngokuzimeleyo, kodwa kwinyathelo lokutshixa ungqamaniso nezinye ezimbini.Ukuba enye yeProcessor iyahlukana, iindlela ezongezelelweyo zivumela uMprosesa ongaphumelelanga ukuba aphinde angqamanise nezinye ezimbini.Iprosesa nganye inojongano olubandakanya umvoti wegalelo, ingqiqo yesixhobo sokungafani, imemori, kunye nojongano lomqhubi webhasi oluphuma kwi-Inter-Module Bus.Isiphumo soMprosesa ngamnye sidityaniswe sisidibanisi semodyuli kumjelo owahlukileyo we-Inter-Module Bus ephindwe kathathu.

3. Isicelo

3.1.Uqwalaselo lwemodyuli I-Trusted TMR Processor ayifuni kubumbeko behardware.Yonke iNkqubo eThenjiweyo ifuna iNkqubo.INI ifayile yoqwalaselo.Iinkcukacha zendlela yokuyila oku zinikwe kwi-PD-T8082 (i-Trusted Toolset Suite).Uqwalaselo luneProsesa eyabelwe kwindawo yasekhohlo yeProsesa ye chassis ngokungagqibekanga.I-Configurator yeNkqubo ivumela ukhetho lweenketho kwizibuko, i-IRIG kunye nemisebenzi yenkqubo.Ukusetyenziswa koMququzeleli weNkqubo kuchazwe kwiPD-T8082.Iinketho zichazwe ngezantsi.

3.1.1.ICandelo loHlaziyo Ukuba i-Auto Protect Network Variables ikhethiwe, oku kuqwalasela iNkqubo eThenjiweyo ukusebenzisa imephu yeProtocol ye-Modbus ecuthiweyo.Jonga inkcazo yemveliso PD-8151B (Imodyuli yoNxibelelwano oluThenjiweyo) ngeenkcukacha ezithe vetshe.I-Inter Group Ukulibaziseka ilingana nomjikelo wohlaziyo lwe-Modbus.Eli lelona xesha lincinane phakathi kwemiyalezo yohlaziyo elandelelanayo ye-Modbus ethunyelwa kwimodyuli nganye yeNxibelelwano yoNxibelelwano.Ixabiso elingagqibekanga (njengoko libonisiwe) yi-50 ms ebonelela ngolungelelwaniso phakathi kwexesha elide kunye nokusebenza.Ulungelelwaniso lwenziwa kwi-32 integer ms increments, okt ixabiso lama-33 liyakulingana no-64 ms njengoko kuya kuba njalo ngaphezu kwe-50 ms, kukho inzuzo encinane ekulungiseni oku kuguquguquka.

3.1.2.ICandelo loKhuseleko Lo mboniso ungentla usetyenziswa ukuqwalasela igama lokugqitha elivumela umsebenzisi ukuba agocagoce iNkqubo eThenjiweyo esebenzisa i-Windows-based HyperTerminal uncedo okanye inkqubo efanayo yeterminal.Igama lokugqitha liqwalaselwe ngokukhetha Igama Lokugqithisa Elitsha iqhosha kwaye ungenisa igama lokugqitha elitsha kabini kwibhokisi yencoko yababini ebonisiweyo.

3.1.3.ICS2000 Icandelo Eli candelo lisebenza kuphela kwiiNkqubo eziThenjiweyo eziqhagamshelwe nge-Trusted ukuya kwi-ICS2000 Interface Adapter kwinkqubo ye-ICS2000.Oku kuvumela imithombo yedatha yeetheyibhile ezintathu zokulinganisa ukuba zikhethwe.Nceda bhekisa kumboneleli wakho oThembekileyo ngolwazi oluthe vetshe.
