Isishwankathelo seKhompyutha yoNxibelelwano ye-485 yezeShishini kunye ne-IO Interface

Njengesiseko senkqubo yokwenza izinto ngokuzenzekelayo, iikhompyutha zoshishino azidingi nje kuphela ukuba nezakhono zokubala ezizinzileyo nezithembekileyo, kodwa zikwafaneleka ukunxibelelana kakuhle ukuze zilungelelanise iimeko ezahlukeneyo zoshishino ezintsonkothileyo. Phakathi kwazo, iikhompyutha zoshishino ezine-interfaces ze-IO kunye nenkxaso yeenkqubo zonxibelelwano ezingama-485 zibaluleke kakhulu ekufezekiseni utshintshiselwano lwedatha kunye nokudluliselwa kwesignali yokulawula phakathi kwezixhobo.

1. Inkcazo kunye nomsebenzi we-interface ye-IO

Ujongano lwe-IO, okanye ujongano lokufaka kunye nokuphuma, yindlela ebonakalayo yokuba iikhompyutha zoshishino zinxibelelane nezixhobo zangaphandle. Ngale ndlela yojongano, iikhompyutha zoshishino zinokufumana imiqondiso evela kwiisensa, ii-actuators zolawulo, kunye nokutshintshiselana ngolwazi nezinye iinkqubo zekhompyutha.

Ii-interface ze-IO zihlala ziquka i-digital I/O, i-analog I/O, kunye nee-interfaces zonxibelelwano ezintsonkothileyo ezifana nee-serial ports kunye nee-Ethernet ports.

2. Intshayelelo kwiProtokholi yoNxibelelwano engama-485

Iprotokholi yonxibelelwano ye-RS-485 yindlela yokudlulisa imiqondiso eyahlukeneyo esetyenziswa kakhulu. Ixhasa unxibelelwano olude olunee-node ezininzi. Ngenxa yesakhono sayo sokunciphisa ingxolo esibalaseleyo kunye nomsebenzi wonxibelelwano olunee-point ezininzi, iprotokholi ye-485 ifanelekile kakhulu kwiindawo zoshishino, ingakumbi kwezo meko apho kufuneka khona ukudluliselwa kwedatha okuzinzileyo nokuthembekileyo kwaye kufuneka kuqhagamshelwe izixhobo ezininzi.

3. Iingenelo

Ukusetyenziswa kweprotocol yonxibelelwano ye-485 ziikhompyutha zoshishino kunye ne-interface ye-IO kuneengenelo ezininzi kwiinkqubo ze-automation zoshishino:

Okokuqala, ivumela iikhompyutha zoshishino ukuba zinxibelelane nee-sensors ezahlukeneyo kunye nee-actuators kumgama omde, nto leyo eyandisa kakhulu ukugcinwa kolawulo.

Okwesibini, amandla ayo onxibelelwano olunamanqaku amaninzi athetha ukuba umgca omnye wonxibelelwano unokudibanisa izixhobo ezininzi, nto leyo enciphisa ubunzima kunye neendleko zokufakelwa kweengcingo.

Kwangaxeshanye, iprotocol yonxibelelwano ye-485 ibonelela ngendlela ezinzileyo yokudlulisa idatha kwiinkqubo zokwenza izinto ngokuzenzekelayo kwimizi-mveliso, iqinisekisa ukuthembeka kokudluliselwa kwedatha kunye nokugcina izinga eliphantsi leempazamo nakwiindawo ezinzima kwimizi-mveliso.

4. Ingcebiso yemveliso

Imodeli yemveliso: SIN-S2010MB-XH81MC

Le yikhompyutha yemizi-mveliso ene-rack ye-2U edibanisa ii-interfaces ze-IO ezityebileyo kwaye ixhasa unxibelelwano lwe-485. Ixhasa ii-VGA+VGA+HDMI triple displays, ii-port ze-Ethernet ze-Gigabit ezi-2, ii-port ze-USB ezili-10, kunye nee-port ze-serial ezili-12, kuquka ii-port ze-RS485 ezi-2, ezifanelekileyo ngokukodwa ukuqhagamshela ii-sensors ezahlukeneyo kunye nabalawuli, okwenza ukuqokelelwa kwedatha kunye nolawulo lwezixhobo luchaneke ngakumbi kwaye lusebenze kakuhle.

Ixhotyiswe ngeprosesa yeCore 4, ifanelekile kwimicimbi yemizi-mveliso ngokubanzi; ixhasa iinkqubo zokusebenza ezininzi ezifana neWindows 7/10, iLinux, kwaye iyahambelana nesoftware eyahlukeneyo yesicelo, inika abasebenzisi uluhlu olubanzi lwezinto zokwenza ngokwezifiso kunye neendlela zophuhliso lwesibini.

5. Isiphelo

Ngamafutshane, xa kusakhiwa inkqubo yolawulo oluzenzekelayo oluthembekileyo nolusebenzayo, iikhompyutha zoshishino njenge-SINSMART, exhotyiswe nge-IO interfaces kwaye ixhasa unxibelelwano lwe-485, ngokuqinisekileyo lukhetho olufanelekileyo. IiPC ezingenafeni eziqinileyo kwaye iiPC zoshishino ezifakwe ngaphakathi I-SINSMART ingenza lula uyilo lwenkqubo, iphucule ukusebenza kakuhle konxibelelwano, kwaye iqinisekise uzinzo kunye nokuthembeka kwenkqubo. Oku kunceda ukuzilawula kwemizi-mveliso yanamhlanje ukuba kufezekise ulawulo olukrelekrele nolunobungcali. Ukongeza, Iikhompyutha ze-Advantech zoshishino inika amandla ekhompyutha aqinileyo kwizicelo zoshishino ezifuna amandla.

Ukulawula nokubeka esweni izinto eziphathwayo, iiPC zeethebhulethi zoshishino ezineWindows kwaye iipilisi zemizi-mveliso zokwenza zibonelela ngezisombululo eziguquguqukayo nezihlala ixesha elide. Kwimisebenzi efuna ukuseta okunokwandiswa, iirakhi zePC zoshishino qinisekisa ulawulo olusebenzayo lwezixhobo zekhompyutha. Kwakhona, iikhompyutha zelaptop zoshishino inika ikhompuyutha ethembekileyo yeselfowuni kweli candelo, ifanelekile kwimisebenzi ekude.

Njengomntu othembekileyo umenzi weekhompyutha zoshishino, I-SINSMART iqinisekisa ukuba zonke ezi zisombululo zenzelwe ukuhlangabezana neemfuno ezifunekayo zokwenza izinto ngokuzenzekelayo kwimizi-mveliso yanamhlanje.
