Ukubuka konke kwe-485 Communication Industrial Computer ene-IO Interface

Njengomgogodla wohlelo lokuzenzakalela, amakhompyutha ezimboni awadingi nje kuphela ukuba namakhono okusebenzisa ikhompyutha azinzile futhi athembekile, kodwa futhi anokuhambisana okuhle kokuxhumana ukuze azivumelanise nezimo ezahlukahlukene zezimboni eziyinkimbinkimbi. Phakathi kwawo, amakhompyutha ezimboni ane-interface ye-IO kanye nokusekelwa kwezinqubo zokuxhumana ezingu-485 kubaluleke kakhulu ekufezeni ukushintshaniswa kwedatha kanye nokudluliswa kwesignali yokulawula phakathi kwamadivayisi.

1. Incazelo kanye nomsebenzi wesixhumi esibonakalayo se-IO

Isixhumi esibonakalayo se-IO, noma isixhumi esibonakalayo sokufaka nokuphuma, siyindlela ebonakalayo yamakhompyutha ezimboni yokusebenzisana namadivayisi angaphandle. Ngalezi zixhumi, amakhompyutha ezimboni angathola amasignali avela kuzinzwa, ama-actuator okulawula, kanye nokushintshana ngolwazi nezinye izinhlelo zekhompyutha.

Izixhumi ze-IO zivame ukufaka i-digital I/O, i-analog I/O, kanye nezixhumi zokuxhumana eziyinkimbinkimbi njengezixhumi ze-serial kanye nezixhumi ze-Ethernet.

2. Isingeniso ku-485 Communication Protocol

Iphrothokholi yokuxhumana ye-RS-485 iyindlela yokudlulisa isignali yokuhlukanisa esetshenziswa kabanzi. Isekela ukuxhumana okuqondile okude, okunama-node amaningi. Ngenxa yekhono layo elihle kakhulu lokuvimbela umsindo kanye nomsebenzi wokuxhumana onama-point amaningi, iphrothokholi ye-485 ifaneleka kakhulu ezindaweni zezimboni, ikakhulukazi kulezo zimo lapho kudingeka khona ukudluliselwa kwedatha okuzinzile nokuthembekile futhi kudinga ukuxhunywa amadivayisi amaningi.

3. Izinzuzo

Ukusetshenziswa kwephrothokholi yokuxhumana engu-485 ngamakhompyutha ezimboni kuhlanganiswe ne-interface ye-IO kunezinzuzo eziningi ezinhlelweni zokwenza izinto ngokuzenzakalela kwezimboni:

Okokuqala, kuvumela amakhompyutha ezimboni ukuthi axhumane nezinzwa ezahlukahlukene kanye nama-actuator amabanga amade, okwandisa kakhulu ukumbozwa kokulawula.

Okwesibili, ikhono layo lokuxhumana elinamaphoyinti amaningi lisho ukuthi umugqa owodwa wokuxhumana ungaxhuma amadivayisi amaningi, okunciphisa ubunzima kanye nezindleko zokuxhuma izintambo.

Ngesikhathi esifanayo, iphrothokholi yokuxhumana ye-485 inikeza indlela yokudlulisa idatha ezinzile yezinhlelo zokwenza izinto ngokuzenzakalela kwezimboni, iqinisekisa ukuthembeka kokudluliselwa kwedatha futhi igcina izinga lamaphutha eliphansi ngisho nasezindaweni ezinzima zezimboni.

4. Izincomo zomkhiqizo

Imodeli yomkhiqizo: SIN-S2010MB-XH81MC

Lena ikhompyutha yezimboni ene-rack engu-2U ehlanganisa izixhumanisi ze-IO ezicebile futhi isekela ukuxhumana okungu-485. Isekela izibonisi ezintathu ze-VGA+VGA+HDMI, amachweba amabili e-Gigabit Ethernet, amachweba ayi-10 e-USB, kanye namachweba ayi-12 alandelanayo, kufaka phakathi amachweba amabili e-RS485 alandelanayo, afaneleka kakhulu ukuxhumanisa izinzwa nabalawuli abahlukahlukene, okwenza ukuqoqwa kwedatha kanye nokulawulwa kwemishini kube nenembile futhi kusebenze kahle.

Ifakwe iprosesa ye-Core 4, ifaneleka emicimbini evamile yezimboni; isekela izinhlelo zokusebenza eziningi ezifana ne-Windows 7/10, i-Linux, futhi iyahambisana nesofthiwe yezinhlelo zokusebenza ezahlukahlukene, inikeza abasebenzisi izinketho eziningi zokwenza ngokwezifiso kanye nezinketho zokuthuthukiswa kwesibili.

5. Isiphetho

Ngamafuphi, lapho kwakhiwa uhlelo lokulawula oluzenzakalelayo oluthembekile nolusebenzayo, amakhompyutha ezimboni njenge-SINSMART, ehlonyiswe ngezixhumi ze-IO futhi esekela ukuxhumana kwe-485, ngokungangabazeki iyisinqumo esifanele. Ama-PC angenawo ama-fan aqinile futhi ama-PC ezimboni afakiwe I-SINSMART ingenza kube lula ukwakheka kwesistimu, ithuthukise ukusebenza kahle kokuxhumana, futhi iqinisekise ukuzinza nokuthembeka kwesistimu. Lokhu kusiza ukuzenzekela kwezimboni zesimanje ukuthi kufezwe ukulawula okuhlakaniphile nokuyinkimbinkimbi. Ngaphezu kwalokho, Ama-PC ezimboni e-Advantech hlinzeka ngamandla aqinile ekhompyutha ukuze kusetshenziswe izinhlelo zokusebenza zezimboni ezidinga kakhulu.

Ukulawula nokuqapha kweselula, ama-PC ethebhulethi yezimboni ane-Windows futhi amaphilisi ezimboni okukhiqiza inikeza izixazululo eziguquguqukayo nezihlala isikhathi eside. Ngemisebenzi edinga ukusethwa okunwebekayo, ama-racks e-PC ezimboni qinisekisa ukuphathwa kwehadiwe okusebenzayo. Futhi, amakhompyutha ezincwadi zamabhuku ezimboni ukuletha ikhompyutha yeselula ethembekile ensimini, efanelekela imisebenzi ekude.

Njengomuntu othembekile umkhiqizi wamakhompyutha ezimboni, i-SINSMART iqinisekisa ukuthi zonke lezi zixazululo zenzelwe ukuhlangabezana nezidingo ezidingakalayo zokwenza izinto ngokuzenzakalela kwezimboni zanamuhla.
