Tilmaamaha iyo Farqiga u dhexeeya Baska CAN iyo RS485

Tilmaamaha baska CAN:

1. Heerka caalamiga ah ee heerka warshadaha baska, gudbinta la isku halayn karo, waqtiga dhabta ah ee sare;

2. Fogaanta gudbinta dheer (ilaa 10km), heerka gudbinta degdega ah (ilaa 1MHz bps);

3. Hal bas ayaa isku xidhi kara ilaa 110 nood, tirada noodhkana si fudud ayaa loo ballaadhin karaa;

4. Qaabdhismeedka sayidkiisa badan, heerka siman ee dhammaan qanjidhada, isku xidhka gobolka ku habboon, isticmaalka baska sare;

5. Tiknoolajiyada gar-qaadidda baska-waqtiga-dhabta ah ee-sare, aan wax-burburin, dib-u-dhac uma laha noodhka leh mudnaanta sare;

6. Noodka CAN ee khaldan ayaa si toos ah u xidhi doona oo jaraya xidhiidhka baska, iyada oo aan wax saamayn ah ku yeelan xidhiidhka baska;

7. Fariintu waa qaab dhismeed gaaban waxayna leedahay hubinta qalabka CRC, oo leh suurtogalnimada faragelinta hoose iyo heerka khaladka xogta aad u hooseeya;

8. Si toos ah u ogow in farriinta si guul leh loo diray iyo in kale, qalabkuna si toos ah ayuu u gudbin karaa, iyada oo la isku halleyn karo gudbinta sare;

9. Shaqada shaandhaynta fariinta qalabku waxay heli kartaa oo kaliya macluumaadka lagama maarmaanka ah, waxay yaraynaysaa culayska CPU, waxayna fududaynaysaa diyaarinta software-ka;

10. Lammaanaha qalloocan ee caadiga ah, fiilada coaxial ama fiber indhaha ayaa loo isticmaali karaa warbaahinta isgaarsiinta;

11. Nidaamka baska CAN wuxuu leeyahay qaab-dhismeed fudud iyo waxqabad qiimo sare leh.

 

RS485 sifooyinka:

1. Tilmaamaha korantada ee RS485: macquulka "1" waxaa matalaya + (2-6) V farqiga u dhexeeya laba xariiq;Logic "0" waxaa ka dhigan farqiga danab u dhexeeya laba khadadka sida - (2-6) V. Haddii heerka signal interface ka yar yahay RS-232-C, ma fududa in la dhaawaco chip ee wareegga interface ah, iyo heerkani wuxuu la jaan qaadayaa heerka TTL, kaas oo fududayn kara isku xirka wareegga TTL;

2. Heerka gudbinta xogta ugu badan ee RS485 waa 10Mbps;

3. RS485 interface waa isku-darka darawalka dheellitiran iyo qaataha kala duwan, kaas oo kor u qaadaya awoodda looga hortagayo faragelinta qaabka caadiga ah, taas oo ah, faragelinta dhawaaqa wanaagsan;

4. Masaafada ugu badan ee gudbinta qiimaha caadiga ah ee RS485 waa 4000 cagood, taas oo dhab ahaantii gaari karta 3000 mitir.Intaa waxaa dheer, hal transceiver oo keliya ayaa loo oggol yahay in lagu xiro RS-232-C interface ee baska, taas oo ah, awoodda hal saldhig.Interface-ka RS-485 waxa uu ogolaanayaa ilaa 128 transceivers in lagu xidho baska.Taasi waa, waxay leedahay awooda saldhigyo badan, markaa isticmaalayaashu waxay isticmaali karaan hal RS-485 interface si ay si sahlan u abuuraan shabakada qalabka.Si kastaba ha ahaatee, hal gudbiye kaliya ayaa ku gudbin kara baska RS-485 wakhti kasta;

5. Interface RS485 waa interface serial la door biday sababtoo ah xasaanadda qaylada wanaagsan, fogaanta gudbinta dheer iyo awoodda saldhigyo badan;

6. Sababtoo ah shabakadda laba-laabka ah ee ka kooban RS485 interfaces waxay guud ahaan u baahan tahay laba fiilo oo keliya, RS485 interfaces waxaa lagu kala qaadaa lammaane qalloocan oo gaashaan leh.

Farqiga u dhexeeya baska CAN iyo RS485:

1. Xawaaraha iyo fogaanta: Fogaanta u dhaxaysa CAN iyo RS485 ee la isugu gudbiyo xawaarihiisa sare ee 1Mbit/S kama badna 100M, taas oo la odhan karo waxay la mid tahay xawaaraha sare.Si kastaba ha ahaatee, xawaaraha hooseeya, marka CAN uu yahay 5Kbit/S, masaafada ayaa gaari karta 10KM, iyo xawaaraha ugu hooseeya ee 485, wuxuu gaari karaa oo kaliya 1219m (masixiye).Waxaa la arki karaa in CAN ay leedahay faa'iidooyin dhammaystiran xagga gudbinta fogaanta;

2. Ka faa'iidaysiga baska: RS485 waa hal sayid oo ah qaab-dhismeedka addoonta, taas oo ah, waxaa jiri kara hal sayid oo keliya baska, xidhiidhkana waxaa bilaabay.Ma bixiso amar, qanjidhada soo socdaa ma soo diri karaan, waxayna u baahan tahay inay soo dirto jawaab degdeg ah.Ka dib markii la helo jawaab, martigeliyaha wuxuu weydiinayaa noodhka xiga.Tani waa si looga hortago noodhyo badan inay u diraan xogta baska, taasoo keenta jahawareer xogta.Baska CAN waa qaab-dhismeed addoon ah oo badan, oo nood kastaa wuxuu leeyahay kantaroolaha CAN.Marka qanjidhada badan ay soo diraan, waxay si toos ah u garqaadi doonaan lambarka aqoonsiga ee la soo diray, si xogta baska ay u noqoto mid wanaagsan oo qallafsan.Kadib hal nood soo diro, noodh kale ayaa ogaan kara in baska uu xor yahay oo isla markiiba soo diri kara, kaas oo kaydiya waydiinta martida loo yahay, wanaajisa heerka isticmaalka baska, korna u qaado xawaaraha.Sidaa darteed, baska CAN ama basaska kale ee la midka ah ayaa loo adeegsadaa nidaamyada leh shuruudaha waxqabadka sare sida baabuurta;

3. Habka ogaanshaha qaladka: RS485 kaliya waxay qeexaysaa lakabka jireed, laakiin maaha lakabka isku xirka xogta, sidaas darteed ma aqoonsan karto khaladaadka ilaa ay jiraan qaar ka mid ah wareegyada gaaban iyo khaladaadka kale ee jirka.Sidan oo kale, way fududahay in la burburiyo noodhka oo loo diro xogta baska si quus ah ( diritaanka 1 mar kasta), taas oo curyaami doonta baska oo dhan.Sidaa darteed, haddii noodhka RS485 uu ku guuldareysto, shabakada baska ayaa xirmi doonta.Baska CAN wuxuu leeyahay kantaroolaha CAN, kaas oo ogaan kara khalad kasta oo baska.Haddii ciladku dhaafto 128, si toos ah ayaa loo xiri doonaa.Ilaali baska.Haddii noodhka kale ama khaladaadkooda la ogaado, khaladaadka xidhmooyinku waxa loo diri doona baska si loo xasuusiyo noodhadhka kale in xogtu khaldan tahay.Iska jir qof walba.Sidan oo kale, mar alla markii barnaamijka noode CPU ee baska CAN uu cararo, koontaroolayaashiisu si toos ah ayuu u xiri doonaa oo u ilaalin doonaa baska.Sidaa darteed, shabakada leh shuruudaha amniga sare, CAN waa mid aad u xoogan;

4. Qiimaha iyo kharashka tababarka: Qiimaha qalabka CAN wuxuu ku saabsan yahay laba jeer ka badan 485. Sidan, 485 isgaarsiineed ayaa aad ugu habboon marka la eego software.Ilaa inta aad fahanto isgaadhsiinta taxanaha ah, waad barnaamij kartaa.Halka CAN ay u baahan tahay injineerka hoose si uu u fahmo lakabka adag ee CAN, iyo kombuyutarka sare ee software sidoo kale wuxuu u baahan yahay inuu fahmo borotokoolka CAN.Waxa la odhan karaa kharashka tababarku wuu badan yahay;

5. Baska CAN waxa uu ku xidhan yahay baska jidhka ee dhex mara CANH iyo CANL ee labada terminal ee wax soo saarka ee CAN controller interface chip 82C250.Terminalka CANH waxa uu noqon karaa mid heer sare ah ama la hakiyay, halka CANL-na waxa ay noqon kartaa mid heer hoose ah ama la hakiyay.Tani waxay hubinaysaa in, sida shabakada RS-485, marka nidaamku leeyahay khaladaad iyo noodes badan ayaa u soo dira xogta baska isku mar, basku wuxuu noqon doonaa mid gaaban oo wareeg ah, sidaas darteed waxyeello u geysanaya qanjidhada qaarkood.Intaa waxaa dheer, qanjidhada CAN waxay leedahay shaqo ah inay si toos ah u xirto wax soo saarka marka qaladku uu yahay mid halis ah, si aan u saameynin shaqada qanjidhada kale ee baska, si loo hubiyo in aysan jirin wax dhibaato ah oo ku saabsan shabakada, iyo basku waxa uu ku jiri doonaa xaalad "xirnaan" sababtoo ah dhibaatooyinka qanjidhada gaarka ah;

6. CAN waxay leedahay nidaam isgaarsiineed oo qumman, kaas oo lagu xaqiijin karo chip kontoroolka CAN iyo chip interface, sidaas darteed si weyn u yareynaya dhibka horumarinta nidaamka iyo soo gaabinta wareegga horumarinta, taas oo aan la barbar dhigi karin RS-485 oo kaliya oo leh borotokoolka korantada.

 

Shenzhen Zhongling Technology Co., Ltd., tan iyo markii la aasaasay ee 2013, waxaa ka go'an in warshadaha robot wheel, horumarinta, soo saarista iyo iibinta wheel hub servo matoorada iyo darawallada leh waxqabadka xasilloon.Darawalada servo hub ee waxqabadka sare leh, ZLAC8015, ZLAC8015D iyo ZLAC8030L, waxay qaataan isgaarsiinta baska CAN/RS485, siday u kala horreeyaan waxay taageertaa nidaamyada hoosaadka CiA301 iyo CiA402 ee borotokoolka CANopen/modbus RTU; kor u qaadi kara aaladaha 16Waxay taageertaa xakamaynta booska, xakamaynta xawaaraha, xakamaynta qulqulka iyo hababka kale ee shaqada, waxayna ku habboon tahay robots waqtiyo kala duwan, si weyn u kor u qaadaya horumarinta warshadaha robotka.
