RJ45 interface ndeye network network network yekubatanidza interface, iyo inoshandiswa kubatanidza makomputa, switch, routers, modem uye zvimwe zvishandiso kune yemunharaunda nharaunda network (LAN) kana wide area network (WAN). Iine pini sere, pakati peiyo 1 uye 2 inoshandiswa kutumira zviratidzo zvakasiyana, uye 3 uye 6 inoshandiswa kugamuchira zviratidzo zvakasiyana-siyana maererano, kuvandudza kukwanisa kwekudzivirira-kupindira kwekutumira zviratidzo. Pini 4, 5, 7 uye 8 inonyanya kushandiswa kugadzira pasi nekudzivirira, kuve nechokwadi kugadzikana kwekufambiswa kwechiratidzo.
Kuburikidza neRJ45 interface, piritsi-yakaiswa mumotokari inogona kutumira data nemamwe maturusi etiweki (senge ma routers, switch, nezvimwewo) nekumhanya kwakanyanya uye kwakadzikama, kusangana nezvinodiwa zvetiweki kutaurirana uye multimedia varaidzo.
RS485
RS485 interface ihafu-duplex serial yekutaurirana interface, iyo inoshandiswa kune maindasitiri otomatiki uye data kutaurirana. Iyo inotora musiyano wechiratidzo chekufambisa modhi, kutumira uye kugamuchira data kuburikidza nembiri yemasaini mitsara (A uye B). Iyo ine yakasimba anti-kupindira kugona uye inogona kunyatso kurwisa kukanganiswa kwemagetsi, kukanganiswa kweruzha uye masaini ekukanganisa munharaunda. Iyo yekufambisa kureba kweRS485 inogona kusvika ku1200m isina inodzokorora, izvo zvinoita kuti ive shasha mumashandisirwo anoda kureba data data. Iyo yakawanda nhamba yezvishandiso iyo bhasi yeRS485 inogona kubatanidzwa ndeye 32. Tsigira michina yakawanda yekutaurirana pabhazi rimwe chete, izvo zviri nyore kune centralized management uye kutonga. RS485 inotsigira kukurumidza-kumhanyisa data kutapurirana, uye chiyero kazhinji chinogona kusvika ku10Mbps.

RS422 interface ndeye yakazara-duplex serial yekutaurirana interface, iyo inobvumira kutumira uye kugamuchira data panguva imwe chete. Yakasiyana masaini ekufambisa modhi inogamuchirwa, mitsara miviri yechiratidzo (Y, Z) inoshandiswa kutapurirana uye mitsara miviri yechiratidzo (A, B) inoshandiswa pakutambira, inogona kunyatso ramba kukanganiswa kwemagetsi uye kupindira kwepasi loop uye kuvandudza zvakanyanya kugadzikana uye kuvimbika. yekutumira data. Iyo yekufambisa kureba kweRS422 interface yakareba, inogona kusvika 1200 metres, uye inogona kubatanidza anosvika gumi zvishandiso. Uye High-speed data transmission ine chiyero chekutumira che 10 Mbps inogona kuitika.
· RS232
RS232 interface ndeye yakajairwa interface yekutaurirana pakati pemidziyo, inonyanya kushandiswa kubatanidza data terminal michina (DTE) uye data yekutaurirana michina (DCE) kuona kutaurirana, uye inozivikanwa nekureruka kwayo uye kuenderana kwakakura. Nekudaro, iyo maximun yekufambisa kureba ingangoita 15 metres, uye mwero wekutapurirana wakaderera. Iyo yakanyanya kutapurirana mwero inowanzoita 20Kbps.
Kazhinji, RS485, RS422 uye RS232 ese ese serial kutaurirana interface zviyero, asi maitiro avo uye mamiriro ekushandisa akasiyana. Muchidimbu, iyo RS232 interface inokodzera maapplication ayo asingade kure-kure kukurumidza kufambisa data, uye ine kuenderana kwakanaka nemimwe michina yekare uye masisitimu. Kana zvichidikanwa kuendesa data mumativi ese panguva imwe chete uye nhamba yemidziyo yakabatana iri pasi pegumi, RS422 inogona kunge iri sarudzo iri nani. Kana midziyo inodarika gumi ichida kubatanidzwa kana kukurumidza kutapurirana chiyero ichidikanwa, RS485 inogona kunge yakanyanya kunaka.
· GPIO
GPIO seti yepini, inogona kugadzirwa mune yekuisa modhi kana yekubuda modhi. Kana iyo GPIO pini iri mune yekuisa modhi, inogona kugamuchira masaini kubva kune sensors (senge tembiricha, humidity, kuvhenekera, nezvimwewo), uye kushandura aya masaini kuita masaini edhijitari ekugadzirisa piritsi. Kana iyo GPIO pini iri mune yekubuda modhi, inogona kutumira masaini ekudzora kune actuators (senge motors uye mwenje weLED) kuti uwane chaiwo kudzora. GPIO interface inogona zvakare kushandiswa seyemuviri layer interface yemamwe maprotocol ekutaurirana (seI2C, SPI, nezvimwewo), uye mabasa akaomarara ekutaurirana anogona kuitika kuburikidza neakawedzerwa maseketi.
3Rtablet, semutengesi ane ruzivo rwemakore gumi nemasere mukugadzira nekugadzirisa mahwendefa akaiswa mumotokari, yave kuzivikanwa nevadyidzani vepasirese nekuda kweakagadziridzwa masevhisi uye rutsigiro rwehunyanzvi. Kunyangwe ichishandiswa mukurima, mugodhi, manejimendi ezvikepe kana forklift, zvigadzirwa zvedu zvinoratidza kuita kwakanakisa, kuchinjika uye kusimba. Aya ekuwedzera ma interfaces ataurwa pamusoro (CANBus, RS232, nezvimwewo) anogoneka mune zvigadzirwa zvedu. Kana iwe uri kuronga kukwidziridza mafambiro ako uye nekuvandudza kuburitsa nesimba rehwendefa, usazeza kutibata kuti udzidze zvakawanda nezve chigadzirwa uye mhinduro!
