4. Ulwakhiwo lweenkosi ezininzi, imo elinganayo yazo zonke iindawo, uthungelwano lwengingqi olufanelekileyo, ukusetyenziswa kweebhasi eziphezulu;
5. Itekhnoloji ye-arbitration yebhasi yexesha langempela, engonakalisiyo, akukho kulibaziseka kwiinodi ezibaluleke kakhulu;
6. I-NOde ye-CAN engafanelekanga iya kuvala ngokuzenzekelayo kwaye inqumle uxhulumaniso kunye nebhasi, ngaphandle kokuchaphazela unxibelelwano lwebhasi;
7. Umyalezo ungobume besakhelo esifutshane kwaye une-hardware ye-CRC yokutshekisha, kunye namathuba aphantsi okuphazamiseka kunye nereyithi yephutha yedatha ephantsi kakhulu;
8. Khangela ngokuzenzekelayo ukuba umyalezo uthunyelwe ngempumelelo, kwaye i-hardware inokuphinda ithumele ngokuzenzekelayo, ngokuthembeka okuphezulu kokudluliselwa;
9. Umsebenzi wokucoca umyalezo we-hardware unokufumana kuphela ulwazi oluyimfuneko, ukunciphisa umthwalo we-CPU, kwaye wenze lula ukulungiswa kwesofthiwe;
10. Izibini eziphothiweyo eziqhelekileyo, intambo ye-coaxial okanye i-fiber optical ingasetyenziswa njengemidiya yonxibelelwano;
11. Inkqubo yebhasi ye-CAN inesakhiwo esilula kunye nokusebenza kweendleko eziphezulu.
Iimpawu eziphambili zeRS485
1. Iimpawu zombane ze-RS485: i-logic "1" imelwe ngu-+ (2-6) umahluko wombane we-V phakathi kwemigca emibini;Ingqiqo "0" imelwe ngumahluko wombane phakathi kwemigca emibini - (2-6) V. Ukuba inqanaba lesignali yojongano lingaphantsi kweRS-232-C, akukho lula ukulimaza i-chip yesekethe yojongano, kwaye eli nqanaba lihambelana nenqanaba le-TTL, elinokuthi liququzelele uxhulumaniso kunye nesekethe ye-TTL;
2. Ubuninzi bezinga lokudluliselwa kwedatha ye-RS485 yi-10Mbps;
3. I-RS485 i-interface yindibaniselwano yomqhubi olungeleleneyo kunye ne-receiver umahluko, okwandisa ukukwazi ukuxhathisa ukuphazamiseka kwemodi eqhelekileyo, oko kukuthi, ukuphazamiseka kwengxolo elungileyo;
4. Ixabiso eliphezulu lomgama wothumelo lomgangatho we-RS485 interface yi-4000 yeenyawo, enokufikelela ngokwenene kwi-3000 yeemitha.Ukongezelela, i-transceiver enye kuphela ivunyelwe ukuba idibaniswe ne-RS-232-C interface kwibhasi, oko kukuthi, umthamo wesikhululo esisodwa.I-RS-485 interface ivumela ukuya kwi-128 i-transceivers ukuba idibaniswe kwibhasi.Oko kukuthi, inamandla ezikhululo ezininzi, ngoko ke abasebenzisi banokusebenzisa ujongano olulodwa lweRS-485 ukuseka ngokulula inethiwekhi yesixhobo.Nangona kunjalo, isinye kuphela isidluliseli esinokusasaza kwibhasi yeRS-485 nangaliphi na ixesha;
5. Ujongano lwe-RS485 lujongano olukhethwayo lwe-serial ngenxa yokugonywa kwengxolo elungileyo, umgama omde wothumelo kunye nekhono lezitishi ezininzi.;
6. Ngenxa yokuba uthungelwano oluyihafu ye-duplex eyenziwe lujongano lwe-RS485 lufuna ngokubanzi iingcingo ezimbini kuphela, ujongano lwe-RS485 lusasazwa ngeperi ejijekileyo ekhuselekileyo.
Umahluko phakathi kwebhasi ye-CAN kunye ne-RS485:
1. Isantya kunye nomgama: Umgama phakathi kwe-CAN kunye ne-RS485 ehanjiswe kwisantya esiphezulu se-1Mbit / S ayikho ngaphezu kwe-100M, enokuthi ifana ne-high-speed.Nangona kunjalo, ngesantya esiphantsi, xa i-CAN i-5Kbit / S, umgama ungafikelela kwi-10KM, kwaye ngesantya esisezantsi se-485, inokufikelela kuphela malunga ne-1219m (akukho relay).Ingabonwa ukuba i-CAN ineenzuzo ezipheleleyo ekuhanjisweni komgama omde;
2. Ukusetyenziswa kwebhasi: I-RS485 sisakhiwo esinye sekhoboka eliyintloko, oko kukuthi, kunokubakho inkosi enye kuphela ebhasini, kwaye unxibelelwano luqaliswa yiyo.Ayiwukhuphi umyalelo, kwaye iinodi ezilandelayo azikwazi ukuyithumela, kwaye kufuneka ithumele impendulo ngokukhawuleza.Emva kokufumana impendulo, umamkeli ubuza indawo elandelayo.Oku kukuthintela iindawo ezininzi zokuthumela idatha kwibhasi, kubangela ukudideka kwedatha.Ibhasi ye-CAN sisakhiwo samakhoboka amaninzi, kwaye indawo nganye inomlawuli we-CAN.Xa ii-nodes ezininzi zithumela, ziya kulamla ngokuzenzekelayo ngenombolo ye-ID ethunyelwe, ukwenzela ukuba idatha yebhasi ibe yinto enhle kwaye ingcolile.Emva kokuba enye i-node ithumele, enye i-node inokubona ukuba ibhasi ikhululekile kwaye iyithumele ngokukhawuleza, egcina umbuzo womninimzi, iphucula izinga lokusetyenziswa kwebhasi, kwaye ikhulise ukukhawuleza.Ke ngoko, ibhasi ye-CAN okanye ezinye iibhasi ezifanayo zisetyenziswa kwiinkqubo ezineemfuno ezisebenzayo ezifana neemoto;
3. Indlela yokubona impazamo: I-RS485 ichaza kuphela umaleko womzimba, kodwa hayi ikhonkco ledatha, ngoko ayikwazi ukuchonga iimpazamo ngaphandle kokuba kukho iisekethe ezimfutshane kunye nezinye iimpazamo ezibonakalayo.Ngale ndlela, kulula ukutshabalalisa i-node kwaye uthumele idatha kwibhasi ngokukhawuleza (ukuthumela i-1 ngamaxesha onke), eya kukhubaza yonke ibhasi.Ngoko ke, ukuba indawo ye-RS485 ayiphumelelanga, inethiwekhi yebhasi iya kuxhoma.Ibhasi ye-CAN inomlawuli we-CAN, onokubona nayiphi na impazamo yebhasi.Ukuba impazamo idlula i-128, iya kuvalwa ngokuzenzekelayo.Khusela ibhasi.Ukuba ezinye ii-nodes okanye iimpazamo zazo zifunyenwe, izakhelo zeempazamo ziya kuthunyelwa ebhasini ukukhumbuza ezinye iindawo ukuba idatha ayichanekanga.Lumka, wonke umntu.Ngale ndlela, nje ukuba inkqubo ye-CPU ye-node ye-CAN ibhasi ibaleke, umlawuli wayo uya kuzitshixa kwaye akhusele ibhasi.Ke ngoko, kwinethiwekhi eneemfuno eziphezulu zokhuseleko, i-CAN yomelele kakhulu;
4. Ixabiso kunye neendleko zoqeqesho: Ixabiso lezixhobo ze-CAN liphindwe kabini kwi-485. Ngale ndlela, unxibelelwano lwe-485 lulungele kakhulu ngokwe-software.Ngethuba nje uqonda unxibelelwano olulandelelanayo, unokucwangcisa.Ngelixa i-CAN ifuna ukuba injineli esezantsi iqonde umaleko onzima we-CAN, kunye nesoftware yekhompyuter ephezulu kufuneka iqonde iprotocol ye-CAN.Kunokuthiwa iindleko zoqeqesho ziphezulu;
5. Ibhasi ye-CAN ixhunywe kwibhasi ebonakalayo nge-CANH kunye ne-CANL yee-terminals ezimbini zokuphuma kwe-CAN controller interface chip 82C250.I-terminal ye-CANH ingaba kumgangatho ophezulu kuphela okanye unqunyanyisiwe, kwaye i-terminal ye-CANL ingaba kumgangatho ophantsi okanye unqunyanyisiwe.Oku kuqinisekisa ukuba, njengoko kuthungelwano lwe-RS-485, xa inkqubo ineempazamo kwaye ii-nodes ezininzi zithumela idatha kwibhasi ngexesha elifanayo, ibhasi iya kuba yifutshane, ngaloo ndlela yonakalise ezinye iindawo.Ukongeza, i-CAN node inomsebenzi wokuvala ngokuzenzekelayo imveliso xa impazamo inzima, ukwenzela ukuba ukusebenza kwamanye ama-node kwibhasi akuyi kuchaphazeleka, ukwenzela ukuba kuqinisekiswe ukuba akukho ngxaki kwinethiwekhi, kwaye ibhasi iya kuba kwindawo "yokufa" ngenxa yeengxaki zeendawo zokuhlala;
6. I-CAN ine-protocol yonxibelelwano egqibeleleyo, enokuthi iphunyezwe yi-CAN isilawuli chip kunye ne-chip interface yayo, ngaloo ndlela inciphisa kakhulu ubunzima bokuphuhliswa kwenkqubo kunye nokunciphisa umjikelezo wophuhliso, ongenakuqhathaniswa ne-RS-485 kuphela ngeprotocol yombane.
I-Shenzhen Zhongling Technology Co., Ltd., ukususela ekusekweni kwayo ngo-2013, izibophelele kushishino lwerobhothi yamavili, ukuphuhlisa, ukuvelisa nokuthengisa iinjini ze-servo hub yevili kunye nabaqhubi abanomsebenzi ozinzileyo.Abaqhubi bayo beemoto ze-servo hub eziphezulu, i-ZLAC8015, i-ZLAC8015D kunye ne-ZLAC8030L, bamkele unxibelelwano lwebhasi ye-CAN/RS485, ngokulandelelanayo ukuxhasa i-CiA301 kunye ne-CiA402 i-protocol ephantsi ye-CANopen protocol/modbus RTU protocol, kwaye inokunyuka ukuya kwizixhobo ze-16;Ixhasa ulawulo lwesikhundla, ukulawula isantya, ukulawula i-torque kunye nezinye iindlela zokusebenza, kwaye ifanelekile kwiirobhothi kwiimeko ezahlukeneyo, ukukhuthaza kakhulu ukuphuhliswa kweshishini le-robot.
