iimveliso

IS200VAICH1C yi-VME Analog Input/Output (VAIC) yeBhodi eyenziwe nguGeneral Electric njengenxalenye yeMark VI Series esetyenziswa kwiinkqubo zokulawula i-injini yegesi. Ibhodi ye-Analog Input / Output (VAIC) iyamkela i-analog inputs ye-20 kunye nokulawula iziphumo ze-4 ze-analog. Ibhodi nganye ye-terminal yamkela amagalelo ali-10 kunye neziphumo ezi-2. Iintambo zidibanisa ibhodi ye-terminal kwi-rack ye-VME apho ibhodi yeprosesa ye-VAIC ikhona. I-VAIC iguqula amagalelo kumaxabiso edijithali kwaye iwadlulisele kwi-backplane ye-VME kwibhodi ye-VCMI, kwaye emva koko kumlawuli. Ngeziphumo, i-VAIC iguqula amaxabiso edijithali kwimisinga ye-analog kwaye iqhube ezi ngebhodi ye-terminal kwisekethe yabathengi. I-VAIC ixhasa usetyenziso lwe-simplex kunye ne-triple modular redundant (TMR). Xa isetyenziswe kuqwalaselo lwe-TMR, imiqondiso yegalelo kwi-terminal board ifakwe kwii-rack ezintathu zebhodi ye-VME i-R, i-S, ne-T, nganye ine-VAIC. Iimpawu zemveliso ziqhutywa ngesekethe yobunini eyenza ikhoyo ngoku efunekayo kusetyenziswa zontathu ii-VAICs. Kwimeko yokungaphumeleli kwe-hardware, i-VAIC embi isuswe kwimveliso kwaye iibhodi ezimbini eziseleyo ziqhubeka nokuvelisa i-current echanekileyo. Xa isetyenziswe kwi-simplex configuration, ibhodi ye-terminal inikezela ngezibonakaliso zegalelo kwi-VAIC enye, ebonelela ngayo yonke imisinga yeziphumo.
UKUHAMBELANA

Kukho izizukulwana ezibini zebhodi ye-VAIC eneebhodi ze-terminal ezihambelanayo. I-VAIC yoqobo ibandakanya zonke iinguqulelo zangaphambili kunye nokubandakanya i-VAICH1C. I-VAICH1B ibandakanyiwe kwesi sizukulwana. Xa uqhuba iziphumo ze-20 mA ezi bhodi zixhasa ukuya kuthi ga kwi-500 ukumelana nomthwalo ekupheleni kwe-1000 ft ye- #18 ucingo. Esi sizukulwana sebhodi sifuna ibhodi ye-terminal TBAIH1B okanye ngaphambili ukuze isebenze ngokufanelekileyo. Bakwasebenza ngokufanelekileyo ngalo lonke uhlaziyo lweebhodi zetheminali ze-DTAI. I-VAICH1D entsha kunye naluphi na ukukhutshwa okulandelayo kuyilelwe ukuxhasa ukuxhathisa komthwalo ophezulu we-20 mA output voltage drive voltage: ukuya kwi-18 V ifumaneka kwi-terminal board screw terminals. Oku kuvumela ukusebenza kwimithwalo ye-800 kunye ne-1000 ft ye-#18 yocingo olunomda. Esi sizukulwana sebhodi sifuna i-TBAIH1C okanye kamva, okanye naluphi na uhlaziyo lwe-STAI.

Umzobo 1: I-VAIC, i-Analog Input Terminal Boards, kunye neCabling (TMR System)

UKUSEBENZA

Ibhodi ye-VAIC iyamkela i-analog inputs ye-20, ilawula iziphumo ze-analog ze-4, kwaye iqulethe i-signal conditioning, i-analog MUX, i-A / D converter, kunye ne-D / A converter. Uhlobo lwegalelo le-analog, nokuba yi-voltage, i-4-20 mA, okanye ibhodi ye-terminal. Iisekethe ezimbini ze-analog ezine ze-4-20 mA kwaye ezinye ezimbini ziyakwazi ukuqwalasela i-4-20 mA okanye i-0-200 mA. Izinto ezifakwayo kunye neziphumo zineesekethe zokucinezela ingxolo ukukhusela ekuzalweni kunye nengxolo ephezulu yefrikhwensi.

Umzobo we-2: I-VAIC kunye ne-Analog Input Terminal Board, i-Simplex System

Kwinkqubo ye-TMR, amagalelo e-analog aphuma kwii-racks ezintathu zokulawula ukusuka kwi-JR1, JS1, kunye ne-JT1. Amandla e-24 V dc kwi-transducers avela kuzo zontathu ii-racks ze-VME kwaye i-diode OKANYE ikhethwe kwi-terminal board. Imveliso nganye yangoku ye-analog yondliwa yimisinga evela kuzo zontathu ii-VAICs. Imveliso yangoku yangoku ilinganiswa kunye ne-resistor series, eyondla i-voltage emva kwe-VAIC nganye. Isiphumo sesiphumo lixabiso eliphakathi elivotelweyo (i-median) lemisinga emithathu. Eli nani lilandelayo libonisa i-VAIC kulungiselelo lwe-TMR. I-Transmitters / i-transducers inokunikwa amandla ngumthombo we-24 V dc kwinkqubo yokulawula okanye inokunikwa amandla ngokuzimeleyo. I-Diagnostics iliso kwisiphumo ngasinye kunye ne-relay yokuzibulala ikhupha isiphumo esihambelanayo ukuba impazamo ayinakucinywa ngumyalelo ovela kwiprosesa. Izihluzi zehardware kwibhodi yetheminali zicinezela ingxolo yefrikhwensi ephezulu. Izihluzi ezongezelelweyo zesoftware kwiVAIC zibonelela ngohluzo lokugqitha olusezantsi oluqwalaselweyo.

UKUFUMANA KWECOMPRESSOR STALL

I-firmware ye-VAIC ibandakanya ukubonwa kwe-stall ye-turbine compressor yegesi, eyenziwa kwi-200 Hz. Ii-algorithms ezimbini zokumisa zinokukhethwa. Zombini zisebenzisa igalelo le-analog yokuqala, eskenwe kwi-200 Hz. Enye i-algorithm yeyee-injini zegesi ze-LM ezincinci kwaye isebenzisa ii-transducers zoxinzelelo ezimbini (jonga kumfanekiso, i-Algorithm encinci ye-Turbine ye-Gas Turbine Compressor Stall Detection). Enye i-algorithm yeye-injini yegesi enzima kwaye isebenzisa ii-transducers zoxinzelelo ezintathu (jonga kumfanekiso, i-Algorithm ye-Heavy Duty Gas Turbine Compressor Stall Detection Algorithm). Amagalelo exesha langempela ahlulwe kwiiparamitha ezicwangcisiweyo zokucaca. Ipharamitha yeCompStalType ikhetha uhlobo lwe-algorithm efunekayo, nokuba ziitransducer ezimbini okanye ezintathu. PS3 luxinzelelo lokukhupha icompressor. Ukuhla kolu xinzelelo (i-PS3 drop) ibonisa i-compressor stall enokwenzeka. I-algorithm iphinda ibale ireyithi yokutshintsha koxinzelelo lokukhupha, i-dPS3dt, kwaye ithelekisa la maxabiso kunye neeparitha ezicwangcisiweyo ze-stall (KPS3 constants). Uhambo lwe-compressor stall luqalwa yi-VAIC, ethumela isignali kumlawuli apho isetyenziselwa ukuqalisa ukuvala. Isignali yokuvala ingasetyenziselwa ukuseta zonke iivalvu zokuvala i-fuel (FSOV) ngokusebenzisa nayiphi na imveliso ye-relay.

Ii-LED ezintathu phezulu kwiphaneli yangaphambili ye-VAIC zibonelela ngolwazi lobume. Imeko ye-RUN eqhelekileyo ikhazimla eluhlaza, kwaye i-FAIL ibomvu eqinileyo. I-LED yesithathu ibonisa i-STATUS kwaye iqhelekile, kodwa ibonisa i-orenji ezinzileyo ukuba imeko ye-alamu yokuxilonga ikhona ebhodini. Ukuhlolwa koxilongo kubandakanya oku kulandelayo:

• Igalelo ngalinye le-analog linokujongwa komda we-hardware ngokusekelwe kwi-preset (engalungisekiyo) kumanqanaba aphezulu naphantsi abekwe kufutshane neziphelo zoluhlu lokusebenza. Ukuba lo mda ugqithwe isignali yengqiqo iyasetwa kwaye igalelo alisaskenwa. Ukuba nayiphi na i-L3DIAG_VAIC, ebhekisa kwibhodi iphela. Iinkcukacha zoxilongo lomntu ngamnye ziyafumaneka kwibhokisi yesixhobo. Iimpawu zokuxilonga zinokuqhotyoshelwa ngabanye, kwaye emva koko zisetwe ngokutsha nge-RESET_DIA isignali.

• Igalelo ngalinye linokuhlolwa komda wenkqubo ngokusekelwe kumanqanaba aphezulu naphantsi aqwalaselweyo. Le mida ingasetyenziselwa ukuvelisa ii-alam kwaye ingaqwalaselwa ukulungiselela/ukukhubaza, nanjengokuqhotsa/ukungaxhuzuli. RESET_SYS iphinda imisele ingaphandle kwemida.

• Kwiinkqubo ze-TMR, ukuba umqondiso omnye uyahluka kwixabiso elivotelweyo (ixabiso eliphakathi) ngaphezu komda omiselweyo, loo mqondiso uchongiwe kwaye iphoso yenziwe. Oku kunokubonelela ngesalathiso sakwangoko sengxaki ekhulayo kumjelo omnye.

• Ukubeka iliso kwiziphumo ze-D/A, ii-currents ze-output, i-total current, ii-relays zokuzibulala, kunye ne-20/200 mA yokukala ukuhanjiswa; ezi zikhangelwa ukuba zikhona kwaye zinokudala impazamo.

• I-TBAI inesixhobo sayo se-ID esigocagocwa yi-VAIC. I-ID yebhodi ifakwe kwi-chip yokufunda kuphela equkethe inombolo ye-serial yebhodi ye-terminal, uhlobo lwebhodi, inombolo yokuhlaziya, kunye ne-JR, JS, kunye ne-JT yokudibanisa indawo. Xa i-chip ifundwa yi-I / O iprosesa kunye nokungahambi kakuhle kuhlangatyezwana nayo, impazamo ye-hardware yokungahambelani iyadalwa.
