3. High-Speed ​​Serial Link (HSSL) da Parallel Processing Capability

Bayanin Aiki:
Wannan sigar sa hannu ce wacce ke bambanta UCSCH1B daga wasu samfura. HSSL ka'idar sadarwar sadarwa ce ta GE mai girma da ake amfani da ita don kafa tashoshi masu sauri-zuwa-matu, tashoshi na bayanai masu sauri tsakanin mai sarrafawa da takamaiman na'urorin I/O (misali, wasu na'urorin haɗin gada).

Ka'idar Aiki:

• Halayen Protocol: HSSL ƙa'idar sadarwa ce ta aiki tare da ta dogara akan Layer na zahiri na Ethernet. Ba kamar asynchronous TCP/IP sadarwar IONet ba, HSSL yana kafa bututun bayanai na sadaukarwa, ƙayyadaddun lokaci-lokaci tsakanin mai sarrafawa da tsarin I/O. Ana watsa bayanai a cikin sauri mai girma tare da ƙananan ƙa'ida.

• Rarraba Bayanan Daidaitawa: Mai kula da UCSCH1B yana tallafawa har zuwa tashoshi na HSSL masu zaman kansu guda 10 (3 akan gaban panel: R/SL1, S/SL2, T/SL3, da 7 fadada tashar jiragen ruwa da ake samu ta hanyar UCECH1x fadada module). Wannan yana nufin mai sarrafawa zai iya sadarwa a cikin cikakken sauri tare da na'urorin HSSL daban-daban 10 a lokaci guda, tare da kowane tashoshi yana aiki da kansa, yana haifar da babban adadin bandwidth. Wannan ya dace musamman don aikace-aikacen da ke buƙatar musayar bayanai mai sauri tare da tsarin ƙasa masu zaman kansu da yawa, kamar a cikin tsarin jujjuyawar wutar lantarki.

• Ƙayyadaddun Ƙaddara: Kasancewar sadarwa ta aiki tare, jinkirin watsa bayanai akan tashar HSSL yana ƙayyadaddun kuma ana iya faɗi. Wannan yana da mahimmanci don kewayon sarrafa madauki da ke buƙatar lokutan amsawa cikin sauri. Lokacin da aka ɗauka don bayanai don tafiya daga tsarin I/O zuwa mai sarrafawa ya tsaya tsayin daka, yana ba da damar sarrafa algorithms daidai don ramawa ga jinkirin sadarwa, don haka inganta ingancin sarrafawa.

• Haɗin Hardware: Sau da yawa ana taimakawa sarrafa HSSL ta kayan aikin sadaukarwa (misali, FPGA) akan mai sarrafawa, wanda ke sauke babban CPU, yana ba shi damar mai da hankali kan aiwatar da dabarun sarrafawa.

4. Wakilin Filin Embedded (EFA) da Haɗin gwiwar Cloud-Edge

Bayanin Aiki:
EFA ita ce ƙofar UCSCH1B zuwa Intanet na Abubuwa (IIoT). Yana gudana a cikin Linux VM na mai sarrafawa, wanda ke da alhakin tattara bayanan gefen gajimare amintacce da samar da dandamalin kwamfuta na gefe.

Ƙa'idar Aiki:

• Amintaccen Bututun Bayanai:

1. Samun Bayanai: Karatun EFA kawai yana biyan kuɗin da ake buƙata na ainihin lokacin da ake buƙata daga ƙwaƙwalwar ajiyar Mark VIe Control VM ta hanyar hanyar sadarwar kama-da-wane ta ciki. Gine-ginen tsarin yana tabbatar da EFA ba za ta iya rubuta kowane bayanai zuwa ga VM Sarrafa ba, wanda ya ƙunshi ƙira mai aminci.

2. Gudanar da Edge: Kafin aika bayanai zuwa gajimare, EFA na iya aiwatar da jerin ayyukan da ake aiwatarwa a cikin gida, gami da: Tacewar bayanai (cire hayaniya), Matsalolin bayanai (rage watsa bandwidth), Caching Data (ma'amala da katsewar hanyar sadarwa), da Aikace-aikacen Timestamp (tabbatar da tarihin bayanai).

3. Rufewa da Watsawa: Ana rufaffen bayanan da aka sarrafa ta amfani da ka'idodin TLS/HTTPS na masana'antu kuma ana watsa su cikin amintaccen dandamalin girgije na GE's Predix ko wasu sabis na girgije masu goyan baya ta hanyar tashar tashar jiragen ruwa ta IICS na ƙasan mai sarrafawa.

• Ƙididdiga na Edge: Babban darajar EFA ita ce ƙarfin lissafin gefensa. Masu amfani za su iya tura aikace-aikacen da aka haɓaka akan Predix ko aikace-aikacen kwantena na al'ada akan EFA. Waɗannan aikace-aikacen na iya aiki kai tsaye a tushen bayanai, misali:

• Binciken Bayanai na lokaci-lokaci: Yin bincike na FFT na ainihi akan girgizawa da siginar zafin jiki don gano kuskuren kayan aikin injiniya da wuri.

• Ƙimar AI: Gudanar da ƙirar koyo na inji don ba da damar kiyaye tsinkaya dangane da bayanan lokaci-lokaci.

• Haɓaka Ma'ana ta Gida: Yin aiwatar da hadaddun, algorithms ingantawa na latency da ciyar da sakamakon baya ga dabarun sarrafa Mark VIe ta hanyar hanyar sadarwa ta kama-da-wane don tunani.

• Haɗin kai da Sabis na Nisa: EFA tana ba da izini ma'aikata tare da amintaccen rami mai nisa. Injiniyoyin sabis na iya haɗawa cikin aminci zuwa mai sarrafa UCSCH1B da aka tura filin ta hanyar intanit ta amfani da kwamfyutoci ko na'urorin hannu don duba bayanan lokaci na ainihi, zazzage tarihin, ko yin bincike, haɓaka saurin amsa sabis da inganci.

Ƙa'idar Aiki:

• Ƙunƙarar zuciya da Sauyawa a cikin Tsarin Dual:

• Masu kula da UCSCH1B guda biyu suna ci gaba da lura da yanayin lafiyar junansu ta hanyar musayar siginonin '' bugun zuciya '' akan cibiyoyin sadarwar IONet da UDH.

• Suna gudanar da shirye-shiryen sarrafawa iri ɗaya kuma suna sarrafa bayanan shigarwa iri ɗaya. Koyaya, ɗaya kaɗai, wanda aka ayyana azaman Mai Kula da Farko, yana da ikon fitar da umarni zuwa masu kunnawa filin.

• Mai sarrafa madadin yana ci gaba da kwatanta yanayinsa na ciki (sakamakon ƙididdigewa, matsakaicin matsakaici) tare da mai sarrafawa na farko. Idan mai kula da ajiyar ajiya ya gano asarar bugun bugun zuciya na farko, ya tantance ta hanyar binciken kansa cewa jiharsa ta fi girma, ko kuma ta karɓi umarnin sauyawa na waje, tsarin yana haifar da dabarar sauyawa. Tsarin sauyawa yana ƙare a cikin millise seconds. Mai sarrafa ajiyar ajiya yana kunna da'irori na fitarwa kuma yana ɗaukar sarrafa tsarin, tare da ƙarancin damuwa ga tsarin, cimma matsaya mara nauyi.

• Ƙa'idar Haƙuri Laifi a Tsarin TMR:

• Wannan shine mafi girman matakin sakewa. UCSCH1B masu kula da su sun samar da naúrar ma'ana guda ɗaya.

• Ana aika bayanan shigarwa lokaci guda zuwa duka ukun. Kowane mai sarrafawa da kansa yana aiwatar da dabaru kuma yana samar da sakamakon fitarwa.
