Kunamasistimu amaningi asebenzisa amapheya asontekile ezimotweni, njengamasistimu omjovo we-elekthronikhi, amasistimu okuzijabulisa okulalelwayo namavidiyo, amasistimu ama-airbag, amanethiwekhi e-CAN, njll. Amapheya asontekile ahlukaniswe ngamapheya asontekile avikelekile kanye namapheya asontekile angavikelekile.Ikhebula elisontekile elivikelekile linongqimba lwensimbi oluvikelayo phakathi kwekhebula elisontekile nemvilophu engaphandle evikelayo.Ungqimba oluvikelayo lunganciphisa imisebe, luvimbele ukuvuza kolwazi, futhi luvimbele ukuphazamiseka kwamagnetic kwangaphandle.Ukusetshenziswa kwamapheya asontekile avikelekile kunezinga eliphezulu lokudlulisela kunamapheya asontekile angavikelwe afanayo.
Izintambo ezisontekile ezivikelekile, amahhanisi ezintambo ngokuvamile asetshenziswa ngokuqondile nezintambo ezivikelekile eziphelile.Kumapheya asontekile angavikelekile, abakhiqizi abanekhono lokucubungula ngokuvamile basebenzisa umshini wokusonta ukuze basonte.Ngesikhathi sokucubungula noma ukusetshenziswa kwezintambo ezisontekile, amapharamitha amabili abalulekile adinga ukunakwa okukhethekile ibanga elisontekile kanye nebanga elingasonti.
|twist pitch
Ubude bokusonta bepheya elisontekile bubhekisela ebangeni eliphakathi kwamagagasi amabili asondelene noma emikhombeni ku-conductor efanayo (kungabuye kubonakale njengebanga eliphakathi kwamalunga amabili asontekile ohlangothini olufanayo).Bheka Umfanekiso 1. Ubude be-twist = S1 = S2 = S3.
umdwebo ongu-1 wezintambo eziboshiwe
Ubude bokulala buthinta ngqo amandla okudlulisa isignali.Ubude obuhlukile bokulala bunamandla ahlukene okumelana nokuphazamiseka kumasignali wamaza ahlukene.Nokho, ngaphandle kwebhasi le-CAN, izindinganiso ezifanele zamazwe ngamazwe nezasekhaya azisho ngokucacile ubude bokusonta bamapheya asontiwe.I-GB/T 36048 Passenger Car CAN Bus Physical Layer Technical Requirements ibeka ukuthi ububanzi bezintambo ze-CAN bungu-25±5mm (33-50 twist/imitha), obuhambisana nezidingo zobude be-CAN ku-SAE J2284 250kbps ngesivinini esiphezulu. I-CAN yezimoto.okufanayo.
Ngokuvamile, inkampani ngayinye yezimoto inamazinga ayo okumisa ibanga elisontekile, noma ilandela izimfuneko zesistimu encane ngayinye yebanga elisontekile lezintambo ezisontekile.Isibonelo, i-Foton Motor isebenzisa ubude bewintshi obungu-15-20mm;amanye ama-OEM aseYurophu ancoma ukukhetha ubude bewintshi ngokwamazinga alandelayo:
1. CAN ibhasi 20±2mm
2. Ikhebula lesiginali, ikhebuli yomsindo engu-25±3mm
3. Ulayini wokushayela 40±4mm
Ngokuvamile, iphimbo lokusonta lincane, liba ngcono ikhono eliphikisayo lensimu kazibuthe, kodwa ububanzi bocingo nobubanzi bokugobeka bempahla yomgodla wangaphandle kudingeka kucatshangelwe, futhi ibanga elifanele kakhulu lokusonta kufanele linqunywe. ngokusekelwe ebangeni lokudlulisela kanye nobude besiginali.Uma amapheya amaningi asontekile abekwe ndawonye, kungcono kakhulu ukusebenzisa amapheya asontekile anobude obuhlukene bokulala emigqeni yesignali ehlukene ukuze kuncishiswe ukuphazamiseka okubangelwa ukuguquguquka okufanayo.Umonakalo wokufakwa kwezintambo okubangelwa ubude obuqinile bokusonta ungabonakala esithombeni esingezansi:
Umfanekiso 2 Ukuguqulwa kwentambo noma ukuqhekeka okubangelwa ibanga eliqine kakhulu lokusonteka
Ngaphezu kwalokho, ubude be-twist bamapheya asontekile kufanele bugcinwe bulingana.Iphutha lephimbo elisontekile lepheya elisontekile lizothinta ngokuqondile ileveli yakhona yokunqanda ukuphazamiseka, futhi ukungahleliwe kwephutha lephimbo elisontekile kuzodala ukungaqiniseki ekubikezelweni kwe-twisted pair crosstalk.Amapharamitha wemishini yokukhiqiza epheya ephothiwe Isivinini se-angular shaft ezungezayo siyisici esibalulekile esithinta usayizi wokuhlanganisa okufakwayo kokupheya okusontekile.Kufanele kucatshangelwe ngesikhathi senqubo yokukhiqiza epheya esontekile ukuze kuqinisekiswe ikhono lokulwa nokugxambukela lepheya elisontekile.
|Ibanga elingasontiki
Ibanga elingasonti libhekisela kusayizi wengxenye engasontiwe yamakhondatha apheya asontekile adinga ukuhlukaniswa lapho efakwe emgodleni.Bheka Umfanekiso 3.
Umfanekiso 3 Ibanga elingaguquki L
Ibanga elingasontiyo alicacisiwe kumazinga omhlaba.Izinga lemboni yasekhaya i-QC/T29106-2014 "Izimo Zobuchwepheshe Zokubopha Izintambo Zezimoto" libeka ukuthi ibanga elingasonti akumele libe likhulu kuno-80mm.Bheka Umfanekiso 4. I-SAE 1939 ejwayelekile yaseMelika ibeka ukuthi ipheya esontekile yemigqa ye-CAN akumele yeqe u-50mm ngosayizi ongasontiwe.Ngakho-ke, izimiso ezijwayelekile zemboni yasekhaya ayisebenzi emigqeni ye-CAN ngoba mikhulu ngosayizi.Njengamanje, izinkampani ezehlukene zezimoto noma abakhiqizi bezintambo zokuhlanganisa izintambo bakhawulela ibanga elingasontiyo lemigqa ye-CAN enesivinini esikhulu ukuya ku-50mm noma 40mm ukuze kuqinisekiswe ukuzinza kwesiginali ye-CAN.Isibonelo, ibhasi le-CAN laseDelphi lidinga ibanga elingasontiyo elingaphansi kuka-40mm.
Umfanekiso 4 Ibanga elingaguquki elicaciswe ku-QC/T 29106
Ukwengeza, phakathi nenqubo yokucubungula izintambo zocingo, ukuze kuvinjwe izintambo ezisontekile ukuthi zingakhululeki futhi zibangele ibanga elikhulu elingaguquki, izindawo ezingaphenduliwe zezintambo ezisontekile kufanele zihlanganiswe neglue.I-American standard ye-SAE 1939 ibeka ukuthi ukuze kugcinwe isimo esisontekile samakhondatha, amashubhu ancipha ukushisa adinga ukufakwa endaweni engasonti.Izinga lemboni yasekhaya i-QC/T 29106 ibeka ukusetshenziswa kwe-tape encapsulation.
|Isiphetho
Njengenkampani ehambisa isignali, izintambo ezisontekile ezisontekile zidinga ukuqinisekisa ukunemba nokuzinza kokudluliswa kwesignali, futhi kufanele zibe namandla amahle okumelana nokuphazamiseka.Usayizi wephimbo le-twist, ukufana kwephimbo lokusonta kanye nebanga elingasontiyo lentambo esontekile kunomthelela obalulekile ekhonweni layo lokulwa nokuphazamiseka, ngakho-ke kudinga ukunakwa ngesikhathi sokuklama nokucubungula.
