ibicuruzwa

IS200VAICH1C nubuyobozi bwa VME Analog Yinjiza / Ibisohoka (VAIC) byakozwe na General Electric nkigice cya Mark VI Series ikoreshwa muri sisitemu yo kugenzura gaz turbine. Ubuyobozi bwa Analog bwinjiza / Ibisohoka (VAIC) byakira ibyinjira 20 bigereranya kandi bigenzura ibisubizo 4 bisa. Buri cyicaro cyanyuma cyakira ibyinjira 10 nibisohoka 2. Intsinga zihuza ikibaho cya terefone na VME aho ikibaho cya VAIC giherereye. VAIC ihindura inyongeramusaruro kubiciro bya digitale ikohereza hejuru yindege ya VME kubuyobozi bwa VCMI, hanyuma ikabigenzura. Kubisubizo, VAIC ihindura indangagaciro ya digitale igereranya kandi ikayitwara binyuze mukibaho cyanyuma mukuzunguruka kwabakiriya. VAIC ishyigikira byombi simplex na triple modular redundant (TMR). Iyo ikoreshejwe muburyo bwa TMR, ibimenyetso byinjira kumurongo wanyuma byashyizwe kumurongo wa VME eshatu R, S, na T, buri kimwe kirimo VAIC. Ibisohoka bisohoka bitwarwa numuzunguruko wihariye ukora ibyifuzwa ukoresheje VAIC zose uko ari eshatu. Mugihe habaye gutsindwa ibyuma, VAIC mbi ikurwa mubisohoka kandi imbaho ​​ebyiri zisigaye zikomeza gutanga umusaruro ukwiye. Iyo ikoreshejwe muburyo bworoshye, ibibaho byanyuma bitanga ibimenyetso byinjiza kuri VAIC imwe, itanga inzira zose ziva mubisubizo.
KUBONA

Hariho ibisekuru bibiri byubuyobozi bwa VAIC hamwe nibibaho byanyuma. VAIC yumwimerere ikubiyemo verisiyo zose mbere kandi harimo VAICH1C. VAICH1B iri muri iki gisekuru. Iyo utwaye 20 mA isohoka izi mbaho ​​zishyigikira kwihanganira imitwaro igera kuri 500 kurangiza 1000 ft ya # 18 wire. Iyaruka ryibibaho risaba ikibaho cya TBAIH1B cyangwa mbere kugirango gikore neza. Bakora kandi neza nibisubirwamo byose byubuyobozi bwa DTAI. VAICH1D nshyashya nibisohoka byose byateguwe kugirango bishyigikire imitwaro iremereye kuri 20 mA isohoka ya moteri ya voltage: kugeza kuri 18 V iraboneka kumurongo wanyuma wa screw. Ibi byemerera gukora mumitwaro ya 800 hamwe na 1000 ft ya # 18 wire hamwe na margin. Iki gisekuru cyinama gisaba TBAIH1C cyangwa nyuma, cyangwa gusubiramo STAI.

Igishushanyo 1: VAIC, Ikigereranyo cyinjiza Ikibaho cya Terminal, na Cabling (Sisitemu ya TMR)

GUSHYIRA MU BIKORWA

• Shyira hasi VME itunganya rack

• Shyira mu kibaho hanyuma usunike hejuru no hepfo hejuru ukoresheje amaboko yawe kugirango wicare impande zombi

• Komeza imigozi yabanyagwa hejuru no hepfo yumwanya wimbere

GUKORESHA

Ubuyobozi bwa VAIC bwakiriye inyongeramusaruro 20 zigereranya, bugenzura ibisubizo 4 bisa, kandi bikubiyemo ibimenyetso byerekana ibimenyetso, igereranya MUX, A / D ihindura, hamwe na D / A. Ubwoko bwikigereranyo cyinjiza, haba voltage, 4-20 mA, cyangwa ikibaho cyanyuma. Babiri muri bane basohokana ibintu bisohoka ni 4-20 mA naho izindi ebyiri zishobora gushyirwaho kuri 4-20 mA cyangwa 0-200 mA. Ibyinjira nibisohoka bifite urusaku rwo guhagarika urusaku kugirango birinde urusaku rwinshi n urusaku rwinshi.

Igishushanyo 2: VAIC na Analog Iyinjiza Terminal Board, Sisitemu yoroshye

Muri sisitemu ya TMR, analog yinjiza umufana hanze yuburyo butatu bwo kugenzura kuva JR1, JS1, na JT1. Imbaraga za 24 V dc kuri transducers ziva mubice bitatu bya VME kandi ni diode CYANGWA byatoranijwe kurubaho. Buri kigereranyo kigezweho gisohoka gitangwa ningaruka ziva VAIC zose uko ari eshatu. Ibisohoka nyabyo byapimwe hamwe nuruhererekane rurwanya, rugaburira voltage kuri buri VAIC. Ibisubizo bivamo ni amajwi yatowe hagati (median) yingendo eshatu. Igishushanyo gikurikira cyerekana VAIC muburyo bwa TMR. Transmitters / transducers irashobora gukoreshwa nisoko ya 24 V dc muri sisitemu yo kugenzura cyangwa irashobora gukoreshwa mu bwigenge. Kwipimisha bikurikirana buri gisohoka kandi kwiyahura bihagarika ibisohoka bijyanye niba ikosa ridashobora gukosorwa n itegeko ryaturutse kuri processor. Ibyuma byungurura kumurongo wanyuma birahagarika urusaku rwinshi. Porogaramu yinyongera muyunguruzi kuri VAIC itanga igenamigambi rito ryo kuyungurura.

UMWANDITSI WO GUHAGARIKA

Porogaramu ya VAIC ikubiyemo gaze ya turbine compressor stall detection, ikorerwa kuri 200 Hz. Imyanya ibiri ihagaze algorithms irashobora gutoranywa. Byombi ukoreshe bine byambere byinjira, bisikana kuri 200 Hz. Algorithm imwe ni ya turbine ntoya ya LM kandi ikoresha transducers ebyiri (reba ishusho, Ntoya (LM) Gas Turbine Compressor Stall Detection Algorithm). Ubundi algorithm ni ya gaz turbine ziremereye kandi ikoresha transducers eshatu (reba igishushanyo, Heavy Duty Gas Turbine Compressor Stall Detection Algorithm). Ibihe-nyabyo byinjira bitandukanijwe nibipimo byagenwe kugirango bisobanuke. Ibipimo CompStalType ihitamo ubwoko bwa algorithm isabwa, haba transducers ebyiri cyangwa eshatu. PS3 nigitutu cyo gusohora compressor. Igitonyanga cyumuvuduko (igitonyanga cya PS3) cyerekana compressor ishobora guhagarara. Algorithm kandi ibara igipimo cyimpinduka zumuvuduko wogusohora, dPS3dt, ikanagereranya izo ndangagaciro hamwe nibikoresho byahagaritswe (KPS3 constants). Urugendo rwo guhagarika compressor rutangizwa na VAIC, yohereza ibimenyetso kumugenzuzi aho ikoreshwa mugutangiza ihagarikwa. Ikimenyetso cyo kuzimya kirashobora gukoreshwa mugushiraho lisansi zose zifunga (FSOV) binyuze mubisohoka byose.

LED eshatu hejuru yumwanya wa VAIC imbere zitanga amakuru yimiterere. Imiterere isanzwe ya RUN irabagirana icyatsi, kandi KUNANUKA ni umutuku ukomeye. LED ya gatatu yerekana STATUS kandi mubisanzwe irazimye, ariko irerekana icunga rihamye niba imiterere yo gutabaza ibaho kurubaho. Igenzura ryo gusuzuma ririmo ibi bikurikira:

• Buri analogi yinjiza ifite ibyuma bigenzurwa bigendeye kubiteganijwe (bitagereranywa) murwego rwo hejuru kandi ruto rwashyizwe hafi yimpera yimikorere. Niba iyi mipaka irenze ibimenyetso byumvikana byashyizweho kandi ibyinjira ntibikibisikana. Niba hari L3DIAG_VAIC, bivuga ikibaho cyose. Ibisobanuro birambuye byo kwisuzumisha birahari uhereye kubikoresho. Ibimenyetso byo kwisuzumisha birashobora gufungwa kugiti cyawe, hanyuma bigasubizwa hamwe nikimenyetso cya RESET_DIA.

• Buri cyinjijwe gifite sisitemu ntarengwa yo kugenzura ishingiye ku gipimo cyo hejuru kandi kiri hasi. Izi mipaka zirashobora gukoreshwa mugutanga impuruza kandi zirashobora gushyirwaho kugirango ushoboze / uhagarike, kandi nkugufunga / kudafunga. RESET_SYS igarura imipaka.

• Muri sisitemu ya TMR, niba ikimenyetso kimwe gitandukana nagaciro katowe (agaciro gaciriritse) kurenza urugero rwateganijwe, icyo kimenyetso kiramenyekana kandi harakozwe amakosa. Ibi birashobora gutanga ibimenyetso byerekana ikibazo gitera imbere mumuyoboro umwe.

• Gukurikirana D / A ibisohoka, ibisohoka, ibyuzuye byose, kwiyahura, hamwe na 20/200 mA ibipimo byerekana; ibi birasuzumwa kubwimpamvu kandi birashobora gutera amakosa.

• TBAI ifite igikoresho cyayo bwite kibazwa na VAIC. Indangamuntu yubuyobozi yanditse muri chip isomwa gusa irimo nimero yuruhererekane yumubare wanyuma, ubwoko bwibibaho, nimero yisubiramo, hamwe na JR, JS, na JT. Iyo chip isomwe na I / O itunganya kandi idahuye, hagaragaye amakosa yibikoresho bidahuye.
