IiNgcaciso zobuGcisa

Inkqubo yoNxibelelwano yeGPIB

Iimpawu zombane kunye noomatshini

Iimpawu zombane zeGPIB ziqinisekisa ukuba imiyalezo ingena ngokucacileyo. Ineempawu ezifana nokuchasa ingxolo kunye nomgangatho wophawu, obalulekileyo kuseto lomsebenzi. Iimpawu zemishini ye-GPIB ziquka izihlanganisi ezinamandla kunye neentambo. Ezi zenziwa ukuba zihlale ngokusebenzisa ezininzi kunye neemeko ezinzima.

Iiprothokholi zonxibelelwano zeGPIB zisebenzisa zombini ugqithiso lwedatha oluhambelanayo kunye noluthotho. Ukuxhawula iintambo ezintathu kweGPIB ngundoqo kwiintetho ezingenazimpazamo. Ikwasebenzisa i-ASCII yemiyalelo kunye nedatha, iyenza isebenze ngezixhobo ezininzi.

Iindidi eziphambili ze-GPIB zokudibanisa zi-24-pin ye-Amphenol connectors. I-GPIB pinout imiselwe ukuphatha idatha kunye nemiyalelo kakuhle. Inemiqolo emibini yezikhonkwane zemisebenzi eyahlukeneyo njengedatha kunye nomhlaba.

Ukwazi ngeempawu zombane ze-GPIB, iindlela zokudlulisa idatha, kunye neentlobo zekhonkco kubalulekile. Inceda ukuqinisekisa ukuba izixhobo zithetha omnye komnye ngokuthembekileyo nangempumelelo kwiindawo ezahlukeneyo.

ULungiselelo lweNkqubo kunye neTopology

Ukumisela inkqubo ye-GPIB kuthetha ukulungisa izixhobo zonxibelelwano olusebenzayo. Kukho ii-topology ezimbini eziphambili: umgca okanye umise okwenkwenkwezi. Kuzo zombini, isixhobo esinye ngumlawuli, ngokuqhelekileyo ikhompyutha, kwaye ezinye zizixhobo.

Umlawuli, okanye umntu othethayo, uqala unxibelelwano kwaye alawule idatha. Izixhobo, okanye abaphulaphuli, benza imisebenzi efana nemilinganiselo kwaye bathumele idatha.

Uqwalaselo olulungileyo lweGPIB luqwalasela izinto ezininzi. Oku kubandakanya idilesi yesixhobo, ukupheliswa, kunye nokuphepha ukubonakalisa uphawu. Itopology yeGPIB ekhethiweyo ichaphazela ubude bekhonkco kunye nenani lezixhobo. Oku kunokutshintsha amazinga okudluliselwa kwedatha.

Impumelelo yofakelo lwe-GPIB ixhomekeke kucwangciso olucokisekileyo. I-hardware efanelekileyo kunye nesofthiwe iqinisekisa ukusebenza kakuhle. Oku kwenza izixhobo zeGPIB zisebenze kakuhle kunye.

Izinto ezilungileyo zeGPIB

Ujongano lweGPIB lukhetho oluphezulu kuvavanyo kunye nehlabathi lokulinganisa. Iyaziwa ngokuthembeka kwayo kwe-GPIB, ngenxa yemigangatho engqongqo. Oku kuthetha ukuba izixhobo zithetha omnye komnye ngokuthembekileyo, zikunika iziphumo ezichanekileyo ngalo lonke ixesha.

Ukuguquguquka kweGPIB kukhanya ngokukwazi ukudibanisa izixhobo ezininzi ezahlukeneyo ngokulula. Oku bhetyebhetye kukuvumela ukuba usete iinkqubo ngeendlela ezininzi, ukwenza uvavanyo lube nezinto ezininzi. Kwaye, ukusetyenziswa kwayo ngokubanzi kuwo wonke amashishini kubonisa ukuba ngumgangatho wonke umntu anokuxhomekeka kuwo.

Ukuhambelana kweGPIB yenye into enkulu. Isebenza kakuhle ngezixhobo ezininzi, kunye nezindala, ezizenza zihlale ixesha elide. Oku kuthetha ukuba ufumana ixabiso elingakumbi kwitekhnoloji yakho, ukongela imali ekuhambeni kwexesha.

Isantya se-GPIB siyakhawuleza, siyenza ibe nkulu kugqithiso lwedatha olukhawulezayo. Oku kungundoqo xa ujongene nedatha eninzi ngokukhawuleza. Ukusebenza kwayo okuqinileyo kwe-GPIB kwiindawo ezinzima kwenza ukuba kubaluleke kakhulu kwiilebhu kunye namaziko ovavanyo.

I-GPIB iyintandokazi phakathi kweengcali ngenxa yokuthembeka kwayo, ukusetyenziswa ngokulula, kunye nokwamkelwa okubanzi. Ihlala ihlangabezana nemigangatho ephezulu, iyenza ibe lukhetho kuninzi.

Imida kunye nemingeni

I-General Purpose Interface Bus inemida yayo. Omnye umda omkhulu we-GPIB ubukhulu bayo bomzimba. Inokudibanisa kuphela inani elithile lezixhobo kanye. Oku kwenza kube nzima ukukhulisa inkqubo yakho.

Omnye umba kukuthintelwa kwebhasi yeGPIB enobude bentambo. Iintambo ezinde zinokonakalisa iiseti ezinkulu. Kwaye, uyilo oludala lweGPIB lucotha kunojongano lwanamhlanje olukhawulezayo.

Ukulungisa iingxaki ze-GPIB zokusombulula ingxaki kunzima. Ukufumana kunye nokulungisa iimpazamo kuthatha ixesha elininzi kunye nobuchule. Uyilo oluntsonkothileyo lwebhasi lwenza kubenzima ukusombulula iingxaki kunetekhnoloji entsha.

Uvavanyo lwe-GPIB nalo lunzima ngakumbi. Oku kwenza ukufumana kunye nokulungisa iingxaki kucotha. Njengoko itekhnoloji ibangcono, ukufumana iindawo ezihambelanayo kuya kuba nzima. Oku kubonisa ukuba sifuna izisombululo ezintsha okanye iindlela zokuqhubela phambili.

IiNdlela ezizezinye zangoku kwi-GPIB

Itekhnoloji iqhubeka ihambela phambili, izisa iinketho ezintsha zokuthatha indawo yeGPIB. I-USB lukhetho oluphezulu lokulula kunye nokulula ukuyisebenzisa. Iziguquli ze-USB ze-GPIB zenza kube lula ukudibanisa iinkqubo ezindala kunye nezixhobo ezitsha, ezinikezela ngokukhawuleza ukudluliselwa kwedatha.

Olunye utshintsho olukhulu zizisombululo ezisekelwe kwi-Ethernet. I-GPIB Ethernet ivumela abasebenzisi ukuba baqhagamshele izixhobo kuthungelwano, okwenza kube lula ukufikelela kwizixhobo ezikude. Oku kukulungele ukuseta ezifuna ukufikelela kude kunye nokudluliselwa kwedatha ngokukhawuleza. I-GPIB ukuya kwi-Ethernet converters inceda ukudibanisa iinkqubo ezindala kwiinethiwekhi zanamhlanje.

I-PXI (i-PCI eXtensions for Instrumentation) nayo iyazuza. Iyaziwa ngoyilo lwayo lweemodyuli kunye nokusebenza okuphezulu. Le teknoloji ifanelekile kwizicelo ezifuna ukuphathwa ngokukhawuleza kwedatha kunye nohlalutyo. Ibonisa ukuba kubaluleke kangakanani ukugcina iinkqubo zisebenza kakuhle ngelixa usebenzisa itekhnoloji yamva nje.
