Hordhaca Waxsoosaarka

Waa maxay Interface Rs-485? Waa maxay astaamaheeda marka la barbar dhigo interface-ka Rs-232-C? Sababo la xiriira muuqaalka hore ee Heerka RS-232-C (2) Xaddiga isgaarsiinta ayaa hooseysa. Gudbinta asynchronon, heerka 'baud' waa 20kbps. (3) Interface-ka waxay isticmaashaa xariiq calaamadaha iyo xariiqda soo laabashada ee calaamadaha si loo sameeyo qaab gudbin ah oo gudbin ah. Isu-gudbinta dhulka ee caadiga ah ayaa u nugul faragalinta qaabka caadiga ah, sidaa darteed caabbinta wacdinta dhawaqa ayaa daciif ah. (4) Masaafada faafinta ayaa xadidan. Qiimaha caadiga ah ee masaafada ugu badan ee gudbinta waa 50 cagood, laakiin waxaa loo isticmaali karaa oo keliya qiyaastii 50 mitir. Marka loo eego wax-ka-ciqaabidda Rs-232-C, qaar ka mid ah heerarka cusub ee is-dhexgalka ayaa soo ifbaxay, oo Rs-485 waa mid ka mid ah. Waxay leedahay astaamaha soo socda: 1. Astaamaha korantada ee Rs-485: caqliga "1" waxaa matalaya farqiga korantada u dhexeeya laba sadar oo ah + (2-6) v; Logic "0" waxaa matalaya farqiga u dhexeeya korantada ee udhaxeysa labada sadar ee - (2-6) V. Heerka calaamadaha isdhaafsiga ayaa ka hooseeya in la jaan qaadayo heerka is dhexgalka, oo si fudud loogu xiri karo wareegga TTL. 2. Heerka gudbinta xogta ugu sareysa ee Rs-485 waa 10 MB PS3. Interface RS-485 waa isku darka isku-dheellitirka darawalka dheelitiran iyo qaataha kaladuwan, kaas oo kor u qaada awooda faragelinta ka hortagga mowduuca caadiga ah, taasi waa, awoodda faragalinta ka hortagga sanqadha ay fiican tahay. 4. Qiimaha heerka ugu sarreeya ee gudbinta ugu badan ee masaafada Rs-485 waa 4,000 cagood, oo runtii gaari kara 3,000 mitir. Intaas waxaa sii dheer, interface Rs-232-C ayaa loo oggol yahay oo keliya inay ku xirato hal transces-ka baska, taasi waa, awoodda keliya ee saldhiga. Interface Rs-485 waxay u oggolaaneysaa xiriirka ilaa 128 ka gudbaya baska. Taasi waa, waxay leedahay awooda sal-dhigno badan, si dadka isticmaala ay si fudud u dhisi karaan shabakadda qalabka iyagoo adeegsanaya hal abuurka Rs-485. Interface rs-485 Interface waa interface-ka la doorbido sababtoo ah faragalinteeda wanaagsan ee ka hortagga dhawaaqa, masaafada dheer ee is-gudbinta iyo awooda saldhiga badan. Sababtoo ah shabakadda badh-nus-ka-badh ee ka kooban Rs485 is-dhexgal guud ahaan waxay u baahan yihiin kaliya laba fiilooyin, Rs485 is-dhexgalka Rs485 9-COME GOST COST OF DB-9 waxaa loo isticmaalaa isku xidhka 'DB488'
