O le a le foliga o le I/O port o se komepiuta fa'apisinisi?

2025-01-06 10:35:45

I le avea ai o se alalaupapa mo komepiuta faʻapisinisi e fegalegaleai ma masini fafo, I / O ports e taua tele ma e fesoʻotaʻi saʻo i le faʻatinoga ma le mautu o le faiga atoa. O le mea lea, o se malamalama loloto o latou ituaiga ma uiga e taua mo tagata faʻapipiʻi ma faʻalapotopotoga. O lenei tusiga o le a suʻesuʻeina ituaiga ma uiga o komipiuta I/O ports ma la latou matafaioi autu i talosaga tau alamanuia.

1. Vaaiga lautele o ports I/O

I/O ports, po'o feso'ota'iga fa'aoga ma fa'aulufalega, o auala ia mo komepiuta fa'apisinisi e maua ma lafo fa'amatalaga. O nei fesoʻotaʻiga e mafai ona faʻafesoʻotaʻi masini eseese, gaioiga, masini fesoʻotaʻiga, ma isi mea e ausia ai le aoina o faʻamaumauga, faʻatonuina le faʻatonuga, ma le mataʻituina o tulaga.

2. Ituaiga I/O uafu

1. Digital I/O

O le ituaiga sili lea ona taatele o le I / O, faʻaaogaina e faʻaogaina ai faʻailoga sui, e pei o le faʻaogaina ma le faʻaogaina o faʻasalalauga, le tulaga tatala ma tapunia o masini, ma isi. Digital I / O e faigofie ma faʻatuatuaina, talafeagai mo le faʻaogaina o le faʻaogaina faigofie ma le mataʻituina o tulaga.

2. Analog I/O

E mafai e le analog I/O ona fa'agasolo fa'asolo suiga fa'ailo, e pei o le voltage po'o fa'ailo o lo'o iai nei e ala i masini e pei o le vevela, mamafa, ma le tafe. O lenei ituaiga o I / O uafu e masani ona manaʻomia le faʻaaogaina ma se A / D converter e ausia ai le liua i le va o faʻailoga analog ma faʻailoga numera.

3. Fa'asalalauga feso'ota'iga fa'asologa

E pei o le RS-232 ma le RS-485, o nei fesoʻotaʻiga e masani ona faʻaaogaina e iloa ai le tuʻuina atu o faʻamatalaga i le va o komipiuta faʻapisinisi ma masini fafo, e pei o PLC, faʻaliliu taimi, ma isi fesoʻotaʻiga fesoʻotaʻiga Serial e talafeagai mo le mamao, maualalo le saoasaoa o faʻasalalauga faʻamatalaga, ma e faigofie le uaea.

3. I/O uafu uiga

1. Uiga eletise: e aofia ai le voltage faʻaogaina, o loʻo i ai nei, faʻalavelave, ma isi. O nei taʻiala e fuafua ai le ituaiga faʻailoga ma le tulaga maualuga e mafai ona taulimaina e le I / O port.

2. Tele faʻaletino: O le tele o le tino ma foliga o le I / O port, e pei o le DB9, DB25, RJ45, ma isi, e aʻafia ai le filifilia o fesoʻotaʻiga ma le faʻaogaina o uaea.

3. Faʻailoga faʻailoga: O le ituaiga faʻailoga e lagolagoina e le I / O port, e pei o le numera numera, faʻailoga analog, faʻamaumauga faʻasologa, ma isi mea, e fuafua ai lona fanua faʻaoga ma le ituaiga o meafaigaluega fesoʻotaʻi.

4. Puipuiga masini o I/O uafu

1. Tu'u'ese'esega fa'aa'oa'oga: E maua le fa'a'ese'esega fa'aeletise e ala i le fa'aulu fa'atasiga e puipui ai ports I/O mai le fa'ate'ia eletise ma le fa'alavelave leo.

2. Puipuiga i luga ole laiga: E fa'aogaina mea fa'apipi'i voltase fe'avea'i po'o fa'asologa o le diode e puipuia ai le fa'aleagaina o ports I/O e mafua mai i le uila po'o le fesuiaiga o le eletise.

5. Faaiuga

Mo i latou o loʻo suʻeina le tulaga maualuga Advantech alamanuia PC filifiliga, o lo'o i ai fofo fa'apitoa e maua. Afai e mana'omia e lau talosaga le fa'aleleia atili o tomai fa'atusa, mafaufau i se PC pisinisi ma le GPU mo galuega mamafatu. E le gata i lea, o pisinisi o loʻo sailia ni fofo faʻapitoa e mafai ona suʻesuʻe pisinisi PC ODM 'au'aunaga e fa'amalieina mana'oga fa'apitoa.

Mo seti fa'apipi'i fa'amau, Advantech rackmount PC faiga e ofoina atu fofo malosi talafeagai mo talosaga server. Galulue faatasi ma se faatuatuaina fa'atau oloa PC fa'apisinisi rackmount fa'amautinoa le avanoa i faiga maualuga ma tumau. E lē gata i lea, tagata gaosi komepiuta fa'apipi'i tu'uina atu faiga fa'apitoa ma lelei mo si'osi'omaga fa'atapula'aina avanoa.

Afai e te manaʻomia mautu ma faʻatuatuaina fale gaosi oloa Saina, e mafai ona e valaʻau fale gaosi oloa komepiuta SINSMART auaunaga fa'atau ma tautuaina oe ma le loto atoa.

Muamua: Malamalama fa'avae ma su'esu'ega ole komipiuta fa'apisinisi 232 fa'aoga

Sosoo ai: E fa'afefea ona filifili le PPU mo komepiuta fa'apisinisi?
