zvigadzirwa

IS200VAICH1C iVME Analog Input/Output (VAIC) Board yakagadzirwa neGeneral Electric sechikamu cheMark VI Series inoshandiswa mumagetsi ekudzora turbine. Iyo Analog Input/Output (VAIC) bhodhi inogamuchira makumi maviri eanalogi yekupinda uye inodzora 4 kubuda kweanalogi. Imwe neimwe terminal board inogamuchira gumi ekuisa uye 2 zvabuda. Matambo anobatanidza terminal board kune VME rack uko VAIC processor board iripo. VAIC inoshandura izvo zvinopinda kuita zvedhijitari uye zvinozviendesa pamusoro peVME backplane kune VCMI board, uyezve kune controller. Kune zvinobuda, iyo VAIC inoshandura dhijitari madhijitari kuita analog currents uye inotyaira izvi kuburikidza neiyo terminal board kupinda mutengi wedunhu. VAIC inotsigira ese ari maviri simplex uye katatu modular redundant (TMR) application. Kana ichishandiswa mukumisikidzwa kweTMR, masaini ekuisa pane terminal board anofefeterwa kune matatu VME board racks R, S, uye T, imwe neimwe iine VAIC. Zviratidzo zvekubuda zvinofambiswa nedunhu remuridzi rinogadzira yazvino inodiwa uchishandisa ese matatu maVAIC. Muchiitiko chekukundikana kwehardware, iyo VAIC yakaipa inobviswa kubva pane zvakabuda uye mabhodhi maviri akasara anoramba achibudisa chaiyo ikozvino. Kana ichishandiswa mune simplex kumisikidzwa, iyo terminal bhodhi inopa masaini ekuisa kune imwe chete VAIC, iyo inopa ese emazuvano ezvinobuda.
KUSVIRANA

Kune zvizvarwa zviviri zveVAIC board ine anowirirana terminal mabhodhi. Iyo yekutanga VAIC inosanganisira ese mavhezheni asati uye kusanganisira VAICH1C. VAICH1B inosanganisirwa muchizvarwa chino. Paunenge uchityaira 20 mA zvinobuda mabhodhi aya anotsigira kusvika ku500 mutoro wekupokana pakupera kwe1000 ft ye#18 waya. Ichi chizvarwa chebhodhi chinoda terminal bhodhi TBAIH1B kana kumberi kwekushanda kwakaringana. Ivo vanoshandawo nemazvo neadzokororo ese eDTAI terminal mabhodhi. Iyo nyowani VAICH1D uye chero inoteedzerwa inoburitswa yakagadzirirwa kutsigira yakakwirira mitoro ye20 mA inobuda drive voltage: inosvika 18 V inowanikwa kune terminal board screw terminals. Izvi zvinobvumira kushanda mumitoro ye800 ine 1000 ft ye #18 waya ine margin. Ichi chizvarwa chebhodhi chinoda TBAIH1C kana gare gare, kana chero kudzokorora kweSTAI.

INSTALLATION

• Simbisa pasi VME processor rack

• Svetera mubhodhi uye sundira kumusoro uye kuzasi levers mukati nemaoko ako kuti ugadzike mupendero zvibatanidza

• Simbisa masiruuru ehusungwa kumusoro uye pasi pepanera repamberi

OPERATION

Iyo VAIC board inogamuchira makumi maviri eanalog mapimendi, inodzora 4 analog zvinobuda, uye ine masaini conditioning, analog MUX, A/D converter, uye D/A converter. Mhando yeanalog yekupinda, ingave voltage, 4-20 mA, kana terminal board. Maviri emaseketi mana eanalogi anobuda 4-20 mA uye mamwe maviri anogona kugadzirwa 4-20 mA kana 0-200 mA. Zvinopinza uye zvinobuda zvine ruzha rwekudzvanya sekita kudzivirira kubva pakuvhiya uye ruzha rwepamusoro-frequency.

Mune TMR system, analog inopinza fan kunze kune matatu ekudzora racks kubva JR1, JS1, uye JT1. Iyo 24 V dc simba kune ma transducer anobva kune ese matatu VME racks uye i diode OR yakasarudzwa pane terminal board. Imwe neimwe analog ikozvino inobuda inodyiswa nemhepo kubva kune ese matatu maVAIC. Iyo chaiyo inobuda ikozvino inoyerwa neyakatevedzana resistor, iyo inodyisa voltage kumashure kune yega yega VAIC. Kubuda kunobuda ndiyo yakavhoterwa yepakati kukosha (yepakati) yemafungu matatu. Nhamba inotevera inoratidza VAIC muhurongwa hweTMR. Transmitters/transducers inogona kupihwa simba neiyo 24 V dc sosi mune yekutonga system kana inogona kuvezwa yakazvimirira. Diagnostics inotarisisa yabuda yega uye yekuzviuraya relay inobvisa inoenderana inobuda kana chikanganiso chisingakwanisi kucheneswa nemurairo kubva kune processor. Hardware mafirita paterminal board anodzvanyirira yakakwira-frequency ruzha. Yekuwedzera mafirita esoftware paVAIC anopa inogadziriswa yakaderera pass kusefa.

COMPRESSOR STALL DETECTION

VAIC firmware inosanganisira gasi turbine compressor stall yekuona, inourayiwa pa200 Hz. Maviri stall algorithms anogona kusarudzwa. Ose ari maviri anoshandisa mana ekutanga analog ekuisa, akaongororwa pa200 Hz. Imwe algorithm ndeyediki LM gasi turbines uye inoshandisa maviri ekumanikidza transducer (tarisa kumufananidzo, Diki (LM) Gasi Turbine Compressor Stall Detection Algorithm). Imwe algorithm ndeyeheavy-duty gas turbines uye inoshandisa matatu ekudzvanya transducer (tarisa kumufananidzo, Heavy Duty Gas Turbine Compressor Stall Detection Algorithm). Real-time inputs inoparadzaniswa kubva kune yakagadziriswa parameters yekujekesa. Iyo parameter CompStalType inosarudza rudzi rwegorgorithm inodiwa, ingave matransducer maviri kana matatu. PS3 ndiyo compressor discharge pressure. Kudonha mukumanikidza uku (PS3 kudonha) kunoratidza inogona kuitika compressor stall. Iyo algorithm inoverengerawo chiyero chekuchinja kwekuyerera kudzvanywa, dPS3dt, uye inoenzanisa izvi zvakakosha nematanho akagadziriswa paramita (KPS3 constants). Iyo compressor stall rwendo inotangwa neVAIC, iyo inotumira chiratidzo kune controller uko inoshandiswa kutanga kudzima. Chiratidzo chekuvhara chinogona kushandiswa kuseta ese mavharuvhu ekuvhara mafuta (FSOV) kuburikidza nechero relay inobuda.

Matatu ma LED kumusoro kweVAIC kumberi kwepaneru anopa ruzivo rwemamiriro. Yakajairika RUN mamiriro ari kupenya girini, uye FAIL itsvuku yakasimba. Yechitatu LED inoratidza STATUS uye kazhinji inodzima, asi inoratidza yakadzikama orenji kana yekuongorora alarm mamiriro aripo pabhodhi. Diagnostic cheki dzinosanganisira zvinotevera:

• Yega yega analogi yekupinda ine hardware yekumisikidza yekutarisa zvichibva pane preset (isina-inogadziriswa) yakakwirira uye yakaderera mazinga akaiswa padyo nekumagumo kweiyo inoshanda renji. Kana muganho uyu ukapfuudzwa chiratidzo chepfungwa chinogadzikwa uye iyo yekuisa haichatariswi. Kana paine L3DIAG_VAIC, iyo inoreva bhodhi rose. Ruzivo rwekuongororwa kwemunhu wega rwunowanikwa kubva mubhokisi rekushandisa. Iwo masaini ekuongorora anogona kusungirirwa ega, uye wozogadziridzwa neiyo RESET_DIA chiratidzo.

• Yega yega inopinza ine system yekumisikidza yekutarisa zvichibva pane inogadziriswa yakakwirira uye yakaderera mazinga. Iyi miganho inogona kushandiswa kugadzira maaramu uye inogona kugadzirwa yekugonesa / kudzima, uye seyatching/isina-latching. RESET_SYS inogadzirisa zvakare kunze kwemiganhu.

• Mumasisitimu eTMR, kana chiratidzo chimwe chichisiyana kubva paukoshi yakavhoterwa (yepakati kukosha) nekupfuura muganhu wakatemerwa, chiratidzo ichocho chinoonekwa uye kukanganisa kunogadzirwa. Izvi zvinogona kupa chiratidzo chekutanga chedambudziko ririkuitika mune imwe chiteshi.

• Monitor D/A zvinobuda, kubuda mariri, zvazvino zvino, kuzviuraya relay, uye 20/200 mA scaling relays; izvi zvinoongororwa kuti zvine musoro here uye zvinogona kukonzera kukanganisa.

• TBAI ine ID yayo mudziyo inobvunzurudzwa neVAIC. Iyo ID yebhodhi inoiswa mukuverenga-chete chip ine terminal board serial nhamba, bhodhi mhando, nhamba yekudzokorora, uye iyo JR, JS, uye JT yekubatanidza nzvimbo. Kana iyo chip ichiverengwa neI / O processor uye kusawirirana kunosangana, kukanganisa kwehardware kusawirirana kunogadzirwa.
