Chidule cha 485 Communication Industrial Computer ndi IO Interface

Monga maziko a makina odziyimira pawokha, makompyuta a mafakitale samangofunika kukhala ndi luso lokhazikika komanso lodalirika la makompyuta, komanso kukhala ndi kulumikizana kwabwino kuti agwirizane ndi malo osiyanasiyana ovuta amakampani. Pakati pawo, makompyuta amakampani okhala ndi ma IO interfaces ndi chithandizo cha ma protocol 485 olumikizirana ndi ofunikira kwambiri pakukwaniritsa kusinthana kwa deta ndi kutumiza chizindikiro pakati pa zipangizo.

1. Tanthauzo ndi ntchito ya mawonekedwe a IO

Ma interface a IO, kapena mawonekedwe olowera ndi otulutsa, ndi njira yeniyeni yomwe makompyuta amafakitale amalumikizirana ndi zida zakunja. Kudzera mu ma interface awa, makompyuta amafakitale amatha kulandira zizindikiro kuchokera ku masensa, ma actuator owongolera, ndikusinthana chidziwitso ndi makompyuta ena.

Ma interface a IO nthawi zambiri amakhala ndi ma I/O a digito, ma I/O a analog, ndi ma interface ovuta kwambiri olumikizirana monga ma port otsatizana ndi ma port a Ethernet.

2. Chiyambi cha 485 Communication Protocol

Njira yolumikizirana ya RS-485 ndi njira yofala kwambiri yotumizira ma signali osiyanasiyana. Imathandizira kulumikizana kwakutali komanso kwa ma node ambiri. Chifukwa cha luso lake labwino kwambiri loletsa phokoso komanso ntchito yolumikizirana ya ma node ambiri, njira ya 485 ndi yoyenera kwambiri m'malo opangira mafakitale, makamaka m'malo omwe kutumiza deta kokhazikika komanso kodalirika kumafunika ndipo zida zingapo ziyenera kulumikizidwa.

3. Ubwino

Kugwiritsa ntchito njira yolumikizirana ya 485 ndi makompyuta a mafakitale kuphatikiza ndi mawonekedwe a IO kuli ndi zabwino zambiri mumakina odziyimira pawokha amakampani:

Choyamba, zimathandiza makompyuta a mafakitale kulankhulana ndi masensa ndi ma actuator osiyanasiyana patali, zomwe zimakulitsa kwambiri kufunika kwa ulamuliro.

Chachiwiri, kuthekera kwake kolumikizirana ndi mfundo zambiri kumatanthauza kuti chingwe chimodzi cholumikizirana chingalumikize zida zingapo, zomwe zimachepetsa zovuta komanso mtengo wa mawaya.

Nthawi yomweyo, njira yolumikizirana ya 485 imapereka njira yokhazikika yotumizira deta yamakina odziyimira pawokha a mafakitale, kuonetsetsa kuti kutumiza deta kudalirika komanso kusunga zolakwika zochepa ngakhale m'malo ovuta amakampani.

4. Malangizo a malonda

Chitsanzo cha malonda: SIN-S2010MB-XH81MC

Iyi ndi kompyuta yamakampani yokhala ndi rack ya 2U yomwe imagwirizanitsa ma IO interfaces olemera komanso imathandizira kulumikizana kwa 485. Imathandizira ma VGA+VGA+HDMI triple displays, ma Gigabit Ethernet ports awiri, ma USB ports 10, ndi ma serial ports 12, kuphatikiza ma RS485 serial ports awiri, omwe ndi oyenera kwambiri kulumikiza masensa ndi owongolera osiyanasiyana, zomwe zimapangitsa kuti kusonkhanitsa deta ndi kuwongolera zida zikhale zolondola komanso zogwira mtima.

Pokhala ndi purosesa ya Core 4, ndi yoyenera zochitika zamafakitale; imathandizira machitidwe osiyanasiyana ogwiritsira ntchito monga Windows 7/10, Linux, ndipo imagwirizana ndi mapulogalamu osiyanasiyana, kupatsa ogwiritsa ntchito njira zosiyanasiyana zosinthira ndi njira zina zopititsira patsogolo.

5. Mapeto

Mwachidule, popanga njira yodalirika komanso yothandiza yowongolera zochita zokha, makompyuta a mafakitale Monga SINSMART, yokhala ndi ma interface a IO komanso yothandizira kulumikizana kwa 485, mosakayikira ndi chisankho chabwino kwambiri. Ma PC opanda fan ndi Ma PC a mafakitale ophatikizidwa kuchokera ku SINSMART kungathandize kupanga makina mosavuta, kukonza bwino kulumikizana, ndikuwonetsetsa kuti makinawo ndi okhazikika komanso odalirika. Izi zimathandiza makina odziyimira pawokha amakono kuti akwaniritse kulamulira kwanzeru komanso kwapamwamba. Kuphatikiza apo, Makompyuta a Advantech mafakitale perekani mphamvu yamphamvu yogwiritsira ntchito makompyuta kuti igwiritsidwe ntchito m'mafakitale ovuta.

Pakuwongolera ndi kuyang'anira mafoni, Ma PC a mapiritsi a mafakitale okhala ndi Windows ndi mapiritsi a mafakitale opangira perekani mayankho osinthasintha komanso olimba. Pa ntchito zomwe zimafuna makonzedwe okulirapo, ma PC okhazikika a mafakitale onetsetsani kuti zipangizo zamagetsi zikuyendetsedwa bwino. Komanso, makompyuta a laputopu a mafakitale imapereka makompyuta odalirika a m'manja m'munda, oyenera kugwira ntchito patali.

Monga wodalirika wopanga makompyuta a mafakitale, SINSMART imaonetsetsa kuti mayankho onsewa apangidwa kuti akwaniritse zosowa zofunika kwambiri zamafakitale amakono.
