The SPEEDTRONIC™ Mark V Gas Turbine Control System ndiye chotuluka chaposachedwa kwambiri pamndandanda wopambana kwambiri wa SPEEDTRONIC™. Machitidwe am'mbuyomu anali ozikidwa pa makina opangira ma turbine, chitetezo ndi njira zotsatirira kuyambira chakumapeto kwa zaka za m'ma 1940, ndipo adakula ndikupangidwa ndiukadaulo womwe ulipo. Kugwiritsa ntchito mphamvu zamagetsi zamagetsi, kuteteza ndi kutsatizana kunayamba ndi dongosolo la Mark I mu 1968. Dongosolo la Mark V ndi kukhazikitsidwa kwa digito kwa njira zopangira makina opangira turbine zomwe zaphunziridwa ndikuyengedwa zaka zoposa 40 zachidziwitso chopambana, pa 80% yomwe yakhala ikugwiritsidwa ntchito pogwiritsa ntchito zipangizo zamakono zamagetsi.

SPEEDTRONIC ™ Mark V Gas Turbine Control System imagwiritsa ntchito luso lamakono lamakono, kuphatikizapo olamulira katatu a 16-bit microprocessor, awiri-otatu mwa atatu omwe amavotera voti pazigawo zoyendetsera chitetezo ndi chitetezo ndi Software-Implemented Fault Tolerance (SIFT). Zowongolera zovuta komanso zodzitchinjiriza ndizosowa katatu ndipo zimavoteredwa ndi ma processor onse atatu. Zizindikiro zotulutsa kachitidwe zimavotera pamlingo wolumikizana ndi solenoids yovuta, pamlingo wamalingaliro pazotsatira zotsalira zolumikizana ndi mavavu atatu a coil servo azizindikiro zowongolera za analogi, motero kukulitsa kudalirika kwachitetezo komanso kuthamanga. Module yodzitchinjiriza yodziyimira payokha imapereka kuzindikirika kolumikizidwa ndi ma waya katatu ndikuzimitsa mothamanga kwambiri komanso kuzindikira lawi. Module iyi imagwirizanitsanso jenereta ya turbine ku dongosolo lamagetsi. Kuyanjanitsa kumathandizidwa ndi cheke mu ma processor atatu owongolera.

Mark V Control System idapangidwa kuti ikwaniritse zofunikira zonse zowongolera ma turbine. Izi zikuphatikiza kuwongolera kwamadzi, gasi kapena mafuta onse onse molingana ndi zomwe zimafunikira liwiro, kuwongolera katundu pansi pazigawo zolemetsa, kuwongolera kutentha pansi pazimene zimatha kapena panthawi yoyambira. Kuphatikiza apo, ma inlet guide vanenes ndi jakisoni wamadzi kapena nthunzi amawongoleredwa kuti akwaniritse zotulutsa ndi zofunikira zogwirira ntchito. Ngati kuwongolera mpweya kumagwiritsa ntchito njira za Dry Low NOx, mawonekedwe amafuta ndi kuyaka amayendetsedwa ndi dongosolo la Mark V, lomwe limayang'aniranso momwe zimakhalira. Kutsatizana kwa othandizira kuti alole kuyambika kwathunthu, kutseka ndi kuzizira kumayendetsedwanso ndi Mark V Control System. Chitetezo cha turbine ku zovuta zogwirira ntchito komanso kutchulidwa kwazovuta zimaphatikizidwa mu dongosolo loyambira.

Mawonekedwe ogwiritsira ntchito amakhala ndi chowunikira chojambula chamitundu ndi kiyibodi kuti apereke mayankho okhudzana ndi momwe akugwirira ntchito. Malamulo olowetsa kuchokera kwa woyendetsa amalowetsedwa pogwiritsa ntchito chipangizo choyika cholozera. Njira yotsatsira mkono/exe-cute imagwiritsidwa ntchito poletsa tur-bine kugwira ntchito mosadziwika bwino. Kulankhulana pakati pa mawonekedwe ogwiritsira ntchito ndi kuwongolera kwa turbine kumadutsa mu Common Data processor, kapena , kwa atatu olamulira mapurosesa otchedwa , ndi . Ogwiritsa ntchito mawonekedwe amathandizanso com-
ntchito zamafoni ndi zida zakutali ndi zakunja. Makonzedwe osasankha, pogwiritsa ntchito mawonekedwe osafunikira, amapezeka pamapulogalamu omwe kukhulupirika kwa ulalo wa data wakunja kumaonedwa kuti ndi kofunikira kuti ntchito zamafakitale zipitirire. Ukadaulo wa SIFT umateteza kulephera kwa gawo ndikufalitsa zolakwika za data. Sewero la opareta woyikira kumbuyo, lolumikizidwa mwachindunji ndi makina owongolera, limalola kupitiliza kugwira ntchito kwa turbine ya gasi pokhapokha ngati mawonekedwe oyambira alephera kapena moduli.

Zowunikira zomwe zimapangidwira kuti zithetse mavuto ndizochuluka ndipo zimaphatikizapo "mphamvu-mmwamba," njira zakumbuyo komanso zodziwikiratu zomwe zimatha kuzindikira zolakwika za gulu lowongolera ndi sensa. Zolakwika izi zimazindikiridwa mpaka pamlingo wa board wa gululo komanso pagawo ladera la sensa kapena zida za actuator. Kuthekera kwa kusintha kwa matabwa pa intaneti kumapangidwira pamapangidwe amagulu ndipo kuli
kupezeka kwa masensa a turbine omwe mwayi wokhala ndi thupi komanso kudzipatula kumatheka. Khalani
mfundo, magawo akukonzekera ndi zowongolera zosinthika zimasinthidwa panthawi yogwira ntchito pogwiritsa ntchito chitetezo
dongosolo lachinsinsi kuti mupewe mwayi wosaloledwa.
