imikhiqizo

I-IS200VAICH1C iyibhodi le-VME Analog Input/Output (VAIC) elakhiwe ngabakwaGeneral Electric njengengxenye yochungechunge lwe-Mark VI olusetshenziswa ezinhlelweni zokulawula i-turbine. Ibhodi le-Analog Input/Output (VAIC) lamukela okokufaka kwe-analog okungu-20 futhi lilawula ukuphuma kwe-analog okungu-4. Ibhodi letheminali ngalinye lamukela okokufaka okungu-10 kanye nemiphumela emi-2. Amakhebuli axhuma ibhodi letheminali endaweni yokubeka ye-VME lapho ibhodi lokucubungula le-VAIC likhona. I-VAIC iguqulela okokufaka kumanani edijithali futhi iwadlulisele phezu kwendiza engemuva ye-VME ebhodini le-VCMI, bese kuba isilawuli. Ukuze uthole okuphumayo, i-VAIC iguqula amanani edijithali abe amaza e-analog futhi iwadlulise ebhodini letheminali iwayise kuyisekethe yekhasimende. I-VAIC isekela kokubili izinhlelo zokusebenza ze-simplex ne-triple modular redundant (TMR). Uma isetshenziswa ekucushweni kwe-TMR, amasiginali okokufaka ebhodini letheminali aphenelwa ama-rack amathathu ebhodi e-VME u-R, S, no-T, ngalinye liqukethe i-VAIC. Amasignali okukhiphayo ashayelwa ngomjikelezo wokuphathelene odala owamanje ofunekayo kusetshenziswa womathathu ama-VAIC. Uma kwenzeka ukwehluleka kwe-hardware, i-VAIC embi iyasuswa ekuphumeni futhi amabhodi amabili asele aqhubeka nokukhiqiza okwamanje okulungile. Uma isetshenziswe ekucushweni kwe-simplex, ibhodi letheminali lihlinzeka ngezimpawu zokufaka ku-VAIC eyodwa, ehlinzeka ngawo wonke ama-currents for outputs.
UKUHAMBANA

Kunezizukulwane ezimbili zebhodi le-VAIC elinamabhodi esitheminali ahambisanayo. I-VAIC yoqobo ihlanganisa zonke izinguqulo zangaphambili futhi ezifaka i-VAICH1C. I-VAICH1B ifakiwe kulesi sizukulwane. Uma ushayela okuphumayo okungu-20 mA lawa mabhodi asekela ukumelana nomthwalo okungafika ku-500 ekupheleni kwentambo engu-1000 ft ye-#18. Lesi sizukulwane sebhodi sidinga ibhodi lokugcina i-TBAIH1B noma ngaphambili ukuze lisebenze kahle. Aphinde asebenze kahle ngakho konke ukubuyekezwa kwamabhodi etheminali e-DTAI. I-VAICH1D entsha kakhulu nanoma yikuphi ukukhishwa okulandelayo kuklanyelwe ukusekela ukumelana nomthwalo okuphezulu ku-voltage yedrayivu ephumayo engu-20 mA: kufika ku-18 V iyatholakala kumatheminali isikulufu sebhodi. Lokhu kuvumela ukusebenza emithwalweni engu-800 enezintambo ezingu-1000 ze-#18 ezinomugqa. Lesi sizukulwane sebhodi sidinga i-TBAIH1C noma eyakamuva, noma noma yikuphi ukubuyekezwa kwe-STAI.

Umdwebo 1: I-VAIC, I-Analog Input Terminal Boards, kanye ne-Cabling (TMR System)

UKUFAKA

• Yehlisa i-VME processor rack

• Slayida ebhodini bese ucindezela amalensi aphezulu naphansi ngezandla zakho ukuze uhlalise izixhumi zayo zonqenqema

• Qinisa izikulufo ezibanjiwe phezulu nangaphansi kwephaneli yangaphambili

UKUSEBENZA

Ibhodi le-VAIC lamukela okokufaka kwe-analog okungu-20, lilawula ukuphuma kwe-analog okungu-4, futhi liqukethe isimo sesignali, i-analog MUX, i-A/D converter, kanye nesiguquli se-D/A. Uhlobo lokokufaka kwe-analog, kungaba i-voltage, 4-20 mA, noma ibhodi letheminali. Amasekhethi amabili kwamane akhipha ama-analog angu-4-20 mA kanti amanye amabili angalungiselelwa u-4-20 mA noma 0-200 mA. Okokufaka nokuphumayo kunomjikelezo wokucindezela umsindo ukuze kuvikelwe ekuqhumeni nomsindo wefrikhwensi ephezulu.

Umfanekiso wesi-2: I-VAIC kanye ne-Analog Input Terminal Board, Uhlelo lweSimplex

Kuhlelo lwe-TMR, okokufaka kwe-analog kuphumela kumarack amathathu okulawula ukusuka ku-JR1, JS1, ne-JT1. Amandla angu-24 V dc kuma-transducer avela kuwo womathathu amarack e-VME futhi iyi-diode NOMA ikhethwe ebhodini letheminali. Okukhiphayo ngakunye kwamanje kwe-analog kunikezwa ama-currents asuka kuwo womathathu ama-VAIC. Okukhiphayo kwangempela kwamanje kukalwa nge-resistor yochungechunge, ephakela i-voltage emuva ku-VAIC ngayinye. Umphumela ophumayo uyinani eliphakathi elivotelwe (i-median) lama-currents amathathu. Isibalo esilandelayo sibonisa i-VAIC ngohlelo lwe-TMR. Ama-Transmitter/transducers anganikwa amandla ngumthombo we-24 V dc ohlelweni lokulawula noma anganikwa amandla ngokuzimela. Ukuxilongwa kuqapha okukhiphayo ngakunye futhi i-relay yokuzibulala inqamula okukhiphayo okuhambisanayo uma iphutha lingakwazi ukusulwa ngomyalo ovela kumcubungula. Izihlungi zezingxenyekazi zekhompuyutha ebhodini letheminali zicindezela umsindo wefrikhwensi ephezulu. Izihlungi ezengeziwe zesofthiwe ku-VAIC zinikeza ukuhlunga okulungisekayo kokudlula okuphansi.

UKUTHOLAKALA KWESITILI SE-COMPRESSOR

I-firmware ye-VAIC ihlanganisa ukutholwa kwesitendi se-compressor ye-gas turbine, esetshenziswa ku-200 Hz. Ama-algorithms amabili wetafula angakhethwa. Zombili zisebenzisa okokufaka kokuqala okune kwe-analog, okuskenwe ku-200 Hz. I-algorithm eyodwa ingeyamaturbine egesi e-LM amancane futhi isebenzisa iziguquli zengcindezi ezimbili (bheka umfanekiso, i-Small (LM) Gas Turbine Compressor Stall Detection Algorithm). Enye i-algorithm eyenzelwe izinjini zegesi ezisindayo futhi isebenzisa ama-transducer amathathu (bheka umfanekiso, i-algorithm ye-Heavy Duty Gas Turbine Compressor Stall Detection Algorithm). Okokufaka kwesikhathi sangempela kuhlukaniswe kumapharamitha amisiwe ukuze acaciseleke. Ipharamitha i-CompStalType ikhetha uhlobo lwe-algorithm edingekayo, kungaba ama-transducer amabili noma amathathu. I-PS3 iyingcindezi yokukhipha i-compressor. Ukwehla kwalokhu kucindezela (ukwehla kwe-PS3) kukhombisa indawo ye-compressor engaba khona. I-algorithm iphinda ibale izinga lokushintsha kokucindezela kokukhipha, i-dPS3dt, futhi iqhathanise lawa manani namapharamitha amisiwe wesitolo (KPS3 constants). Uhambo lwe-compressor stall luqalwa yi-VAIC, ethumela isignali kusilawuli lapho isetshenziselwa ukuqalisa ukuvala shaqa. Isignali yokuvala shaqa ingasetshenziswa ukusetha wonke ama-valve okuvala uphethiloli (i-FSOV) ngokusebenzisa noma yikuphi ukuphuma kwe-relay.

Ama-LED amathathu phezulu kwephaneli yangaphambili ye-VAIC ahlinzeka ngolwazi lwesimo. Isimo esijwayelekile se-RUN siluhlaza okotshani, futhi i-FAIL ibomvu okuqinile. I-LED yesithathu ibonisa STATUS futhi ngokuvamile icishiwe, kodwa ibonisa okusawolintshi okungashintshi uma isimo se-alamu yokuxilonga sikhona ebhodini. Ukuhlolwa kokuxilonga kuhlanganisa okulandelayo:

• Okokufaka kwe-analogi ngakunye kunokuhlola umkhawulo wezingxenyekazi zekhompuyutha ngokusekelwe kumazinga amisiwe (okungalungiseki) aphezulu naphansi asethwe eduze kwamaphethelo obubanzi bokusebenza. Uma lo mkhawulo weqiwe isignali enengqondo iyasethwa futhi okokufaka akusaskenwa. Uma ikhona i-L3DIAG_VAIC, ebhekisela kulo lonke ibhodi. Imininingwane yokuxilonga ngakunye iyatholakala ebhokisini lamathuluzi. Izimpawu zokuxilonga zingaxhunywa ngazodwana, bese zisethwa kabusha ngesignali ye-RESET_DIA.

• Okokufaka ngakunye kunokuhlola umkhawulo wesistimu ngokusekelwe kumazinga aphezulu naphansi alungisekayo. Le mikhawulo ingasetshenziselwa ukukhiqiza ama-alamu futhi ingalungiselelwa ukunika amandla/ukukhubaza, nanjengama-latching/non-latching. I-RESET_SYS imisa kabusha okungaphandle kwemikhawulo.

• Ezinhlelweni ze-TMR, uma isignali eyodwa ihluka enanini elivotiwe (inani elimaphakathi) ngaphezu komkhawulo onqunywe kusengaphambili, leyo siginali iyatholwa bese kwakhiwa iphutha. Lokhu kunganikeza inkomba yokuqala yenkinga ekhulayo esiteshini esisodwa.

• Gada imiphumela ye-D/A, imisinga yokuphumayo, inani lamanje, ukudluliselwa kokuzibulala, kanye nokudluliselwa kwesikali okungu-20/200 mA; lezi zihlolelwa ukucabangela futhi zingadala iphutha.

• I-TBAI inedivayisi yayo ye-ID ephenywa nge-VAIC. I-ID yebhodi ifakwe ikhodi ku-chip efundwayo kuphela equkethe inombolo ye-serial yebhodi letheminali, uhlobo lwebhodi, inombolo yokubuyekeza, kanye nendawo yesixhumi se-JR, JS, ne-JT. Uma i-chip ifundwa iphrosesa ye-I/O futhi kuhlangabezana nokungafani, kwakheka iphutha lokungahambelani kwezingxenyekazi zekhompyutha.
