IS200VAICH1C ndi VME Analog Input/Output (VAIC) Board yopangidwa ndi General Electric monga gawo la Mark VI Series lomwe limagwiritsidwa ntchito pamakina owongolera gasi. Bolodi ya Analog Input/Output (VAIC) imavomereza zolowetsa 20 za analogi ndikuwongolera zotuluka 4 za analogi. Bolodi iliyonse yama terminal imavomereza zolowetsa 10 ndi zotuluka 2. Zingwe zimalumikiza bolodi la terminal ku rack ya VME komwe kuli VAIC processor board. VAIC imasintha zolowera kukhala za digito ndikuzitumiza pa VME backplane kupita ku bolodi la VCMI, kenako kwa wowongolera. Pazotuluka, VAIC imatembenuza ma digito kukhala mafunde a analogi ndikuyendetsa izi kudzera mu board board kupita ku kasitomala. VAIC imathandizira mapulogalamu onse a simplex ndi triple modular redundant (TMR). Mukagwiritsidwa ntchito pakusintha kwa TMR, ma siginecha olowera pa bolodi yama terminal amapangidwa ndi ma VME board rack R, S, ndi T, iliyonse ili ndi VAIC. Zizindikiro zotuluka zimayendetsedwa ndi kagawo kakang'ono komwe kamapanga komwe mukufuna kugwiritsa ntchito ma VAIC onse atatu. Pakachitika kulephera kwa hardware, VAIC yoyipa imachotsedwa pazotulutsa ndipo matabwa awiri otsalawo akupitiliza kupanga zolondola. Ikagwiritsidwa ntchito mu masinthidwe a simplex, bolodi la terminal limapereka zizindikiro zolowera ku VAIC imodzi, yomwe imapereka mafunde onse otuluka.
KUGWIRIZANA

Pali mibadwo iwiri ya board ya VAIC yokhala ndi matabwa ofananira. VAIC yoyambirira imaphatikizapo mitundu yonse isanachitike komanso kuphatikiza VAICH1C. VAICH1B ikuphatikizidwa mum'badwo uno. Mukamayendetsa zotulutsa 20 mA matabwawa amathandizira mpaka 500 kukana katundu kumapeto kwa 1000 ft pa #18 waya. M'badwo uno wa bolodi umafunika TBAIH1B yomaliza kapena yoyambirira kuti igwire bwino ntchito. Amagwiranso ntchito moyenera ndi zosintha zonse zama board a DTAI terminal. VAICH1D yatsopano kwambiri ndi zotulutsa zilizonse zotsatizanazi zidapangidwa kuti zithandizire kukana kwamphamvu kwa 20 mA outputs drive voltage: mpaka 18 V imapezeka pa terminal screw board. Izi zimaloleza kugwira ntchito pazambiri za 800 zokhala ndi 1000 ft pa #18 waya wokhala ndi malire. M'badwo uno wa board umafunika TBAIH1C kapena mtsogolo, kapena kusinthidwa kulikonse kwa STAI.

KUYANG'ANIRA

• Yambitsani choyikapo purosesa ya VME

• Yendetsani mu bolodi ndikukankhira pamwamba ndi pansi ndi manja anu kuti mukhazikitse zolumikizira zake zam'mphepete

• Limbani zomangira zomangidwa pamwamba ndi pansi pa gulu lakutsogolo

NTCHITO

Bungwe la VAIC limavomereza zolowetsa 20 za analogi, limayang'anira zotuluka 4 za analogi, ndipo lili ndi mawonekedwe azizindikiro, analogi MUX, chosinthira A/D, ndi chosinthira cha D/A. Mtundu wa kulowetsa kwa analogi, mwina voteji, 4-20 mA, kapena board board. Awiri mwa mabwalo anayi otulutsa analogi ndi 4-20 mA ndipo enawo amatha kusinthidwa kukhala 4-20 mA kapena 0-200 mA. Zolowetsa ndi zotulutsa zimakhala ndi zozungulira zochepetsera phokoso kuti zitetezedwe ku mafunde komanso phokoso lambiri.

Chithunzi 2: VAIC ndi Analog Input Terminal Board, Simplex System

Mu dongosolo la TMR, zolowetsa za analogi zimathamangira kumalo atatu owongolera kuchokera ku JR1, JS1, ndi JT1. Mphamvu ya 24 V dc yopita ku transducers imachokera ku ma rack onse atatu a VME ndipo ndi diode OR osankhidwa pa board board. Kutulutsa kulikonse kwa analogi komweko kumadyetsedwa ndi mafunde ochokera ku ma VAIC onse atatu. Zomwe zimatuluka panopa zimayesedwa ndi zopinga zotsatizana, zomwe zimadyetsa voteji kubwerera ku VAIC iliyonse. Zotsatira zake ndi mtengo wapakati wovoteledwa (wapakatikati) wa mafunde atatuwo. Chithunzi chotsatira chikuwonetsa VAIC mu dongosolo la TMR. Ma transmitters / transducers amatha kuyendetsedwa ndi 24 V dc gwero mumayendedwe owongolera kapena akhoza kuyendetsedwa paokha. Diagnostics imayang'anira zotuluka zilizonse ndipo kutumizirana kodzipha kumachotsa zotulukapo ngati cholakwika sichingathetsedwe ndi lamulo lochokera kwa purosesa. Zosefera za Hardware pa board board zimatsitsa phokoso lambiri. Zosefera zowonjezera pa VAIC zimapereka kusefa kocheperako kosinthika.

KUDZIWA KWA COMPRESSOR STALL

Firmware ya VAIC imaphatikizapo kuzindikiridwa kwa malo opangira makina opangira ma turbine, ochitidwa pa 200 Hz. Ma algorithms awiri osungira amatha kusankhidwa. Onse amagwiritsa ntchito zolowetsa zinayi zoyambirira, zojambulidwa pa 200 Hz. Njira imodzi ndi ya makina ang'onoang'ono a gasi a LM ndipo amagwiritsa ntchito makina osindikizira awiri (onani chithunzi, Small (LM) Gas Turbine Compressor Stall Detection Algorithm). Njira ina ndi ya ma turbine a gasi olemera kwambiri ndipo amagwiritsa ntchito ma transducer atatu (onani chithunzi, Heavy Duty Gas Turbine Compressor Stall Detection Algorithm). Zolowetsa zenizeni zimasiyanitsidwa ndi magawo okonzedwa kuti amveke bwino. CompStalType parameter imasankha mtundu wa algorithm yofunikira, ma transducers awiri kapena atatu. PS3 ndiye mphamvu yotulutsa kompresa. Kutsika kwapanikizi iyi (kudontha kwa PS3) kukuwonetsa kutsika kwa kompresa. Ma aligorivimu amawerengeranso kuchuluka kwa kusintha kwa kuthamanga kwa kutulutsa, dPS3dt, ndikufanizira zikhalidwe izi ndi magawo okhazikika osungira (KPS3 constants). Ulendo wa compressor stall umayambitsidwa ndi VAIC, yomwe imatumiza chizindikiro kwa wolamulira kumene amagwiritsidwa ntchito poyambitsa kutseka. Chizindikiro chotseka chingagwiritsidwe ntchito kukhazikitsa ma valve onse otseka mafuta (FSOV) kudzera muzotulutsa zilizonse zotumizirana.

Ma LED atatu pamwamba pa gulu lakutsogolo la VAIC amapereka chidziwitso. Mkhalidwe wamba wa RUN umakhala wobiriwira, ndipo FAIL ndi yofiira kwambiri. LED yachitatu imawonetsa STATUS ndipo nthawi zambiri imakhala yozimitsa, koma imawonetsa lalanje wokhazikika ngati pali vuto la alamu pa bolodi. Macheke a diagnostic ndi awa:

• Kuyika kulikonse kwa analogi kumakhala ndi kuwunika malire a hardware kutengera zomwe zakhazikitsidwa kale (zosasinthika) zapamwamba komanso zotsika zomwe zimayikidwa pafupi ndi malekezero amtundu wogwirira ntchito. Ngati malirewa apyola chizindikiro cha logic chimayikidwa ndipo zolowetsazo sizimafufuzidwanso. Ngati pali L3DIAG_VAIC, zomwe zikutanthauza gulu lonse. Tsatanetsatane wa diagnostics payekha likupezeka pa Toolbox. Zizindikiro zowunikira zimatha kulumikizidwa payekhapayekha, ndikuyambiranso ndi chizindikiro cha RESET_DIA.

• Kulowetsa kulikonse kumakhala ndi malire a dongosolo kutengera milingo yokhazikika komanso yotsika. Malirewa angagwiritsidwe ntchito kupanga ma alamu ndipo akhoza kukonzedwa kuti athe kuyatsa / kulepheretsa, komanso ngati latching / osatsegula. RESET_SYS imakhazikitsanso malire.

• M'machitidwe a TMR, ngati chizindikiro chimodzi chikusiyana ndi mtengo wovotera (mtengo wapakati) ndi kupitirira malire okonzedweratu, chizindikirocho chimadziwika ndipo cholakwika chimapangidwa. Izi zitha kupereka chidziwitso choyambirira chavuto lomwe likukula munjira imodzi.

• Yang'anirani zotuluka za D/A, mafunde otuluka, zonse zomwe zilipo, zotumizirana zodzipha, ndi ma 20/200 mA makulitsidwe; izi zimafufuzidwa ngati zili zomveka ndipo zimatha kupanga cholakwika.

• TBAI ili ndi ID yakeyake yomwe imafunsidwa ndi VAIC. ID ya board imayikidwa mu chipangizo chowerengera chokha chomwe chili ndi nambala ya serial board, mtundu wa board, nambala yokonzanso, ndi malo olumikizirana a JR, JS, ndi JT. Chipchi chikawerengedwa ndi purosesa ya I / O ndipo kusagwirizana kukuchitika, cholakwika chosagwirizana ndi hardware chimapangidwa.
