Inkcazelo ye-SN65HVD251
I-HVD251 yenzelwe ukusetyenziswa kwizicelo ezisebenzisa i-Controller Area Network (CAN) unxibelelwano olulandelelanayo umaleko womzimba ngokuhambelana ne-ISO 11898 Standard.I-HVD251 inikezela ngesakhono sokudlulisa okwahlukileyo kwibhasi kunye nokwahluka kokufumana amandla kumlawuli we-CAN ngesantya ukuya kwi-1 megabits ngesekhondi (Mbps).
Yenzelwe ukusebenza kwindawo enzima, isixhobo sibonisa i-cross-wire, overvoltage kunye nokulahleka kokhuseleko lomhlaba ukuya kwi-± 36 V. Kwakhona kubonakaliswe ukukhuselwa kobushushu obugqithisileyo kunye ne-7-V ukuya kwi-12-V yendlela eqhelekileyo, kunye nokunyamezela kwizinto ezidlulayo. ye-± 200 V. I-transceiver idibanisa umlawuli we-CAN onesiphelo esisodwa kunye nokwahlukana kwebhasi ye-CAN efunyenwe kwimizi-mveliso, i-automation yokwakha, kunye nezicelo zemoto.
I-Rs, i-pin 8, ikhetha enye yeendlela ezintathu ezahlukeneyo zokusebenza: isantya esiphezulu, ulawulo lwe-slope, okanye imodi yamandla aphantsi.Imowudi yesantya esiphezulu sokusebenza ikhethwa ngokudibanisa i-pin 8 emhlabeni, ivumela i-transmitter output transistors ukuba itshintshe ngokukhawuleza ngaphandle komda wokunyuka kunye nokuwa kwe-slope.Ukunyuka nokuwa kwe-slope kunokulungiswa ngokudibanisa i-resistor kumhlaba kwi-pin 8;Ithambeka lilingana nemveliso yangoku yesikhonkwane.Ulawulo lwe-slope kunye nexabiso langaphandle le-resistor ye-10 kΩ inika malunga ne-15-V / µs isantya sokubulala;I-100 kΩ inika malunga ne-2-V/µs ireyithi yokubulala.
Ukuba inqanaba eliphezulu le-logic lisetyenziswe kwi-Rs pin 8, isixhobo singena kwimodi yokulinda ephantsi yangoku apho umqhubi ucinyiwe kwaye umamkeli uhlala esebenza.Umlawuli weprothokholi yendawo ubuyisela isixhobo kwimo yesiqhelo xa sithumela ebhasini.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
