Zofunika Kwambiri
Zigawo Zofunikira za Serial Port
Kumvetsetsa mbali za doko la serial kumatithandiza kuwona momwe zimagwirira ntchito komanso zomwe zimagwiritsidwa ntchito. Zolumikizira ndi zingwe zomwe zimagwiritsidwa ntchito potumiza deta ndizofunikira. Cholumikizira cha D-subminiature ndichofala kwambiri, chokhala ndi mitundu ngati DE-9 ndi DB-25 pazogwiritsa ntchito zosiyanasiyana.
Kumvetsetsa Zolumikizira Zamtundu
Zingwe za seri, monga chingwe cha null modem, ndizofunikira pakulankhulana kwa chipangizo. Ali ndi mapini enieni otumizira ndi kupeza deta. Izi ndizofunikira kuti zida zizilankhulana.
Kuwongolera magawo amagetsi ndikofunikira pamtundu wa data. Kuthamanga kwa baud, kapena liwiro la data, kumakhudza momwe zida zimagwirira ntchito limodzi. Nayi tebulo lomwe likuwonetsa zolumikizira zofananira:
| Mtundu Wolumikizira | Pin Count | Common Use Cases | Miyezo ya Voltage | Chiyerekezo cha Baud |
| D-subminiature (DE-9) | 9 | Ma PC Akale, Zida Zambiri | -12V mpaka +12V | 300 mpaka 115200 bps |
| DB-25 | 25 | Printers, Modem | -12V mpaka +12V | 300 mpaka 115200 bps |
Kodi ma Seri Ports Amagwira Ntchito Motani?
Kodi Serial Port Amagwiritsidwa Ntchito Bwanji?
Ma serial madoko ndi ofunikira m'malo ambiri, makamaka pamakina opanga makina komanso kulumikizana ndi zida. Amagwirizanitsa mbali zosiyanasiyana za hardware, kupanga kulankhulana bwino. Izi ndi zoona kwa machitidwe akale ndi atsopano, kuonetsetsa kuti akugwira ntchito bwino.
Zolemba ndi Zogwiritsa Ntchito
M'mafakitale, ma serial madoko amalumikiza makina kuti aziwongolera machitidwe. Izi zimawonjezera kuwunika ndikupangitsa kuti ntchito ziziyenda bwino. Ndiwofunikanso pakuwongolera, kuthandiza kupeza ndi kukonza zolakwika panthawi yachitukuko.
Ngakhale machitidwe akale amagwiritsira ntchito madoko a serial, kusonyeza kuti teknolojiyi imakhala yayitali bwanji. Makina ophatikizidwa, monga omwe amalandila GPS, amadaliranso iwo. Ichi ndi chifukwa iwo ayenera kulumikiza zipangizo zosiyanasiyana kutsatira malo.
Kutsanzira kwa Terminal kumagwiritsa ntchito ma doko a serial kuyang'anira zotonthoza. Izi ndizofunikira pakuyendetsa malamulo ndikuwunika makonda adongosolo. Ndikofunikira pakuwongolera zida ndikuwongolera machitidwe bwino.
Ma Seri Ports mu Modern Computing
Madoko a seri angawoneke akale, koma akadali ofunikira lero. Zida zambiri, monga ma adapter a USB, zimapangitsa kuti zikhale zosavuta kuzigwiritsa ntchito ndi machitidwe atsopano. Izi zikutanthauza kuti machitidwe akale ndi zida zambiri zitha kugwiritsabe ntchito ma serial ports.
Chisinthiko ndi Kufunika Kwamakono
Madera ena ofunikira, monga machitidwe owongolera, amafunikirabe ma serial ports. Iwo ndi osavuta ndi odalirika. Njira zatsopano zolumikizira zida zimapangitsa kuti ma serial madoko agwire ntchito ndiukadaulo wamakono. Nayi tebulo lomwe likuwonetsa chifukwa chake ma serial ports akadali othandiza lero.
| Mbali | Zithunzi za seri | USB ndi Ethernet |
| Kugwirizana kwa Legacy | Wapamwamba | Zosintha |
| Njira Yotumizira Data | Seri Data Mitsinje | Paketi-Yotengera |
| Malo Ofunsira | Zida, Control Systems | General Data Transfer |
| Thandizo la Chipangizo | Zodziwika mu Legacy Systems | Zothandizidwa Kwambiri |
| Kumasuka kwa Kuphatikiza | Zimatengera Hardware Abstraction | Nthawi zambiri Zosavuta |
Kukhazikitsa ndi Kukhazikitsa Serial Port
Kukonza doko la serial ndikofunikira kuti zida zizilankhulana. Kukonzekera koyenera kwa doko kumatsimikizira kuti deta yasinthidwa bwino. Choyamba, dziwani zomwe chipangizo chanu chimafuna.| Kukhazikitsa | Kufotokozera |
| Chithunzi cha COM Port | Nambala yadoko yodziwika yoperekedwa ndi opareshoni. |
| Mtengo wa Baud | Liwiro la kutumiza kwa data limayezedwa mu bits pa sekondi iliyonse. |
| Ma Data Bits | Chiwerengero cha ma bits mu paketi iliyonse ya data; muyezo ndi 8 bits. |
| Parity | Njira yowunikira zolakwika, zosankha siziphatikiza, ngakhale, kapena zosamvetseka. |
| Imani Bits | Imawonetsa kutha kwa paketi ya data; kawirikawiri 1 kapena 2 bits. |
| Kuwongolera Kuyenda | Njira yoyendetsera kufalitsa kwa data; zosankha zikuphatikizapo hardware ndi mapulogalamu. |
| Kusintha kwa Signal | Njira zoyendetsera ndikuwongolera kukhulupirika kwa kutumizirana ma data. |
| Mbali | Seri Port | Parallel Port | USB | Efaneti |
| Kutumiza kwa Data | Zotsatizana | Kufanana | Universal (zochokera ku seri) | Phukusi-kusintha |
| Kuchepetsa Kutalikirana | Kutali popanda kunyozeka | Chachidule chifukwa cha crosstalk | Wapakati | Long (ndi kapangidwe ka cabling) |
| Mtundu Wolumikizira | Daisy-chaining | Mfundo ndi mfundo | Hub topology | Network topology |
| Common Use Cases | Zida zamafakitale | Osindikiza akale | Zotumphukira zamakono | Networking ndi intaneti |
Zida ndi Chalk kwa Serial Port Communication
Kulankhulana kogwira mtima kudzera m'madoko angapo kumafunikira zida zapadera ndi zowonjezera. Chipangizo chofunikira ndi serial breakout box, yomwe imathandiza ogwiritsa ntchito kuyang'anira ndi kuthetsa milingo yazizindikiro panthawi yotumizira deta. Chida ichi ndi chofunikira kwambiri pozindikira zovuta munthawi yeniyeni ndikuwonetsetsa kuti ma siginecha akukwaniritsa zofunikira. Kwa malo ovuta, a piritsi lolimba ndi Windows 11 imapereka yankho kunyamula pothana ndi mavuto patsamba.
Zida Zofunika
M'malo opangira mapulogalamu, debugger ndiyofunikira kuti mupeze ndikukonza zolakwika zamapulogalamu zomwe zingakhudze kulumikizana kwanthawi yayitali. Olemba ma data a serial nawonso ndi ofunikira pojambula ndi kusanthula mitsinje ya data, kupereka zidziwitso zamtengo wapatali pamayendedwe anthawi. Pazofunika kuchita bwino kwambiri, a PC yamafakitale yokhala ndi NVIDIA GPU kapena a kompyuta yolimba ya rackmount imatha kuthandizira kusanthula kwakukulu kwa data ndikukonza ntchito.
Mukamagwira ntchito ndi ma microcontrollers ndi zida zina, zoyesa ma cable ndizofunikira kwambiri kuti zitsimikizire kukhulupirika ndi magwiridwe antchito a zingwe za serial. Kuti muwone mawonekedwe a mafunde azizindikiro ndikutsimikizira mitengo ya baud, oscilloscope ndiyofunikira. Pamakhazikitsidwe amakampani, a mafakitale PC Advantech imapereka masanjidwe odalirika, pomwe a PC yolimba kwambiri amapereka njira yaying'ono komanso yolimba. Pazambiri zamagulu ankhondo, lingalirani a makompyuta ankhondo akugulitsidwa kwa mphamvu zowonjezera.
Kumvetsetsa Universal Asynchronous Receiver-Transmitter (UART) ndikofunikiranso pakuwongolera ndi kukhathamiritsa kulumikizana kwa serial moyenera. Chida chilichonse chimathandizira kupanga njira yolumikizirana yolimba kwambiri, kupangitsa kuti kulumikizana pakati pa zida kukhale kosavuta. Kuti mupeze mayankho apamwamba kwambiri, fufuzani zosankha kuchokera kwa odalirika mafakitale opanga makompyuta zimatsimikizira kugwira ntchito ndi kudalirika.
