(1) Mlingo wa siginecha wa mzere ndi kuchuluka kwa ma voliyumu omwe amapangidwa pa sekondi imodzi yowonetsedwa mu bps (bits pamphindikati).
Zizindikiro zina zonse ndi katundu wa eni ake
Chithunzi cha SN65HVD251
HVD251 idapangidwa kuti igwiritsidwe ntchito pamapulogalamu omwe ali ndi Controller Area Network (CAN) serial communication layer molingana ndi ISO 11898 Standard.HVD251 imapereka mwayi wotumizira mosiyanasiyana ku basi ndikulandila kosiyanasiyana kwa wowongolera CAN pa liwiro la 1 megabits pamphindi (Mbps).
Chopangidwa kuti chizigwira ntchito m'madera ovuta, chipangizochi chimakhala ndi waya wodutsa, kuwonjezereka komanso kutayika kwa chitetezo cha pansi ku ± 36 V. Zomwe zimawonekeranso ndi chitetezo cha kutentha kwambiri komanso -7-V mpaka 12-V wamba wamba, komanso kulolerana ndi nthawi yochepa. ya ± 200 V. Transceiver imagwirizanitsa wolamulira wa CAN wamtundu umodzi ndi kusiyana kwa basi ya CAN yomwe imapezeka m'mafakitale, zomangamanga, ndi ntchito zamagalimoto.
Rs, pini 8, imasankha imodzi mwa njira zitatu zosiyana zogwirira ntchito: kuthamanga kwambiri, kuwongolera kotsetsereka, kapena mphamvu zochepa.Njira yogwirira ntchito yothamanga kwambiri imasankhidwa ndikulumikiza pini 8 pansi, kulola ma transmitter output transistors kuti asinthe mwachangu momwe angathere popanda malire pakukwera ndi kugwa kotsetsereka.Kukwera ndi kutsika kotsetsereka kungasinthidwe mwa kulumikiza chopinga pansi pa pini 8;otsetsereka ndi molingana ndi pini yotulutsa pano.Kuwongolera kotsetsereka ndi mtengo wakunja wotsutsa wa 10 kΩ kumapereka pafupifupi 15-V / µs kupha;100 kΩ imapereka pafupifupi 2-V/µs kuphedwa.
Ngati mulingo wapamwamba wamalingaliro umagwiritsidwa ntchito pa Rs pin 8, chipangizocho chimalowa mumayendedwe otsika apano pomwe dalaivala amazimitsidwa ndipo wolandila amakhalabe achangu.Woyang'anira protocol wam'deralo amabwezera chipangizocho kumayendedwe abwinobwino akamadutsa basi.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
