Kuteteza basi ya CAN yagalimoto kuti isabedwe - zabwino ndi zoyipa
Zamkatimu
Pafupifupi m'galimoto iliyonse yamakono, mayunitsi amagetsi "amalumikizana" wina ndi mzake kudzera pa basi ya digito ya CAN. Njinga, chiwongolero, mabuleki ndi zida zina zamagetsi zitha kulumikizidwa ndi gawoli. Wowukira amatha kulembetsa kiyi, kulumikiza "choyambitsa" (chipangizo choyambira injini popanda kiyi), kudutsa loko ya CAN - yambitsani galimotoyo modekha ndikuyendetsa. Kuteteza basi yagalimoto ya CAN kuti isabedwe ndi imodzi mwazinthu zomwe cholinga chake ndikuteteza katundu wanu. Kutsekedwa kwa gawoli sikumakhudza kuyendetsa galimoto, ndi "zosaoneka" (wobera sangathe kudziwa chifukwa cha kutsekereza kowonekera), amatha kuchotsedwa pogwiritsa ntchito pini kapena pini yofunikira.

Kodi module ya CAN ndi chiyani
Kuti mumvetse zomwe basi ya CAN ndi momwe imaperekera chitetezo chakuba galimoto, m'pofunika kuphunzira mfundo za gawoli ndi zoikamo zake. Tiyeni tiwone chifukwa chake owukira sangathe kugwiritsa ntchito galimotoyo.
Mfundo ya ntchito ya CAN-module
Basi ndi gawo lolumikizirana lomwe limalumikizana ndi chitetezo chagalimoto ndikukulolani kuti muwongolere galimotoyo pogwiritsa ntchito mapulogalamu apadera. Node zonse zamakina zimatsatira malamulo okhazikitsidwa omwe amafalitsidwa kudzera pa firmware.
CAN dongosolo chipangizo
Pamene alamu yatsegulidwa, lamulo lofanana limatumizidwa ku basi. Zomwe zimachitika kenako zalembedwa mu pulogalamu ya module iyi. Zambiri zimalowetsedwa pamenepo pogwiritsa ntchito firmware.
Kukhazikitsa gawo la CAN
Mfundo za kukhazikitsa module pamakina zimadalira alamu yomwe yayikidwa. Starline iyenera kulumikizana ndi batani la ntchito, koma izi zisanachitike, mawonekedwe amapulogalamu amayatsidwa. Chidziwitso chokhudza ma siginecha amawu chikufotokozedwa mu malangizo achitetezo.
Momwe mungasinthire magawo a module:
- Dinani batani la service kuti muyambe kupanga.
- Tsegulani gawo lomwe mukufuna, kusankha kudzatsimikiziridwa ndi beep.
- Sankhani njira chimodzimodzi.
- Yembekezerani kuti phokoso likudziwitse kuti dera lomwe mwasankha likhoza kusintha.
- Ngati beep imodzi ikumveka, ndiye kuti parameter imatsegulidwa, awiri - imatsekedwa.
Ngati woyendetsa galimoto asankha kusintha magawo ena, ndiye kuti ayenera kubwereza sitepe 2 ndi yotsatira.
Momwe magalimoto amabedwa kudzera pa basi ya CAN
Njira yoyamba yozembera galimoto ndikuyika "bug" ku waya wagalimoto. Malowo si ofunikira kwambiri, chinthu chachikulu ndikufikira. Kungakhale nyali yakutsogolo, nyali za mchira, zizindikiro zotembenukira. Izi zimangofunika kulimbikitsa ndi kutumiza malamulo ku netiweki wamba. Pambuyo pake, node imodzi kapena zingapo zimapanga lamulo lomwe lafotokozedwa mu chinthu chatsopano cha netiweki.
Kuthyola galimoto chifukwa chakuba
Njira ina ndi maukonde akunja. Nthawi zina ngakhale foni yamakono imagwiritsidwa ntchito ngati makina a multimedia agalimoto omwewo alibe intaneti. Ndikokwanira kulankhulana ndi wailesi kudzera pa Bluetooth. Chokhacho chokha cha njira iyi ndi kusowa kwa foni yam'manja m'galimoto pamene mulibe dalaivala mmenemo.
Njira yomaliza yomwe imagwiritsidwa ntchito ndikuwunikira ma alarm unit. Iyi ndiyo njira yowononga nthawi kwambiri, koma code yoyipa idzatumizidwa pa basi kupita kumalo omwe mukufuna, ndipo idzapereka lamulo la olanda. Kotero izo zalamulidwa kutsegula zitseko, kuyambitsa injini, kuyatsa nyali. Zingwe za pulogalamuyo zimachotsedwa pamene owukirawo amaliza ntchito yawo. Palibe katswiri amene adzawapeza poyang'ana galimotoyo, pamene idzagulitsidwa pamsika wachiwiri ndi zikalata zabodza.
Kuyimitsa injini kudzera pa basi ya CAN
Kuteteza basi ya CAN yagalimoto ya inshuwaransi kuti isabedwe ndi njira imodzi yotetezera katundu wanu. Koma madalaivala ena amadziletsa okha kutsekereza magetsi, poganiza kuti oberawo sangawutsenso alamu, koma amangoyesa kulumikiza ndi kutumiza chizindikiro chomwe akufuna.
Momwe mungalumikizire alamu kudzera pa basi ya CAN
Kuteteza basi ya CAN kuti isabedwe kumaphatikizapo kuyilumikiza ku alamu. Malangizo:
- Ikani alamu ndikuyilumikiza ku mfundo zonse.
- Pezani chingwe cha lalanje, ndicho chachikulu kwambiri, chimazindikira basi ya CAN.
- Gwirizanitsani adaputala yachitetezo kwa iyo.
- Ikani chipangizocho kuti chikhale chokha komanso chokhazikika.
- Khazikitsani njira zoyankhulirana ndi ma node kuti muteteze bwino galimotoyo.
Ngati woyendetsa alibe chidziwitso chokwanira pa izi, ndi bwino kukaonana ndi ntchito yapadera.
Ubwino wosainira ndi basi ya CAN
"Zowonjezera" zazikulu zoyika basi kuti zisayine:
- Woyendetsa galimoto aliyense amene wawerenga malangizo kuchokera kwa wopanga alamu adzatha kupirira kuyika ndi kukonza mapulogalamu.
- Ma nodewo amalankhulana mofulumira kwambiri moti oloŵerera sangathe kutenga galimotoyo.
- Kusokoneza kunja sikumakhudza machitidwe a dongosolo.
- Multilevel monitoring and control systems zilipo. Izi zidzateteza chizindikiro ku zolakwika panthawi yotumiza deta.
- Kuchita bwino kwa module kumatsimikiziridwa ndi kuthekera kwake kugawa liwiro pamakina onse oyikidwa.
- Kusankha kwakukulu. Wokonda galimoto adzatha kusankha njira iliyonse yachitetezo ndi basi ndikuyiyika pagalimoto yake. Zogulitsa pali zinthu zoteteza magalimoto ngakhale magalimoto akale apanyumba.
Mapangidwe a zinthu za CAN
Pali "zowonjezera" zambiri za alamu yotere, koma chachikulu ndikutsutsa olanda.
Kuipa kosayina ndi CAN bus
Ndi mbali zonse zabwino zachitetezo chotere, palinso zoyipa:
- Zoletsa kusamutsa deta. Chiwerengero cha node ndi zipangizo m'magalimoto amakono zikungowonjezereka. Ndipo zonsezi zimagwirizana ndi basi, zomwe zimawonjezera kwambiri katundu pa chinthu ichi. Chifukwa cha kukhudzidwa koteroko, nthawi yoyankha imasintha kwambiri.
- Sikuti zonse zomwe zili m'basi ndizothandiza. Ena a iwo ali ndi mtengo umodzi wokha, zomwe sizimawonjezera chitetezo cha katundu wosunthika.
- Palibe standardization. Opanga amapanga zinthu zosiyanasiyana ndipo zovuta zake zimatengera izi.
Pali "minus" yocheperako, yomwe imafotokoza kufunikira kwakukulu kwa machitidwe otere.
CAN chitetezo mabasi
Kuteteza basi yagalimoto ya CAN kuti isabedwe kumaphatikizapo kukhazikitsa ma diode. Amalepheretsa kutulutsa kwa electrostatic komanso kuthamanga kwamagetsi. Ndi iwo, overvoltage panthawi ya ntchito zina sizimaphatikizidwanso.
CAN kuthyolako basi
Imodzi mwa misonkhanoyi ndi SM24 CANA. Cholinga chake chachikulu ndikuchotsa kutulutsa kobwerezabwereza kwa electrostatic, ngati mulingo wawo uli wapamwamba kuposa wolembedwa mulingo wapadziko lonse lapansi.
Misonkhano yotereyi imapangidwa ndi opanga osiyanasiyana, koma chofunikira kwambiri kwa iwo ndi chiphaso. Chifukwa chovuta ichi ndi kuthekera kolumikizana ndi maulamuliro a "bokosi", injini ndi chitetezo.
Ubwino waukulu wa chitetezo chofotokozedwa:
- chitetezo chapamwamba cha electrostatic discharge - mpaka 30 kV;
- kuchepetsa kukana kwamphamvu - mpaka 0,7 OM;
- kuchepetsa chiopsezo cha kutayika kwa deta;
- kuchepetsa kutayikira panopa;
- kuthekera koyika ngakhale pamagalimoto akale apanyumba.
CAN chitetezo cha mabasi sichofunikira, koma chimakulolani kuti musakhale ndi chikoka cha anthu ena pa dongosolo, zomwe zikutanthauza kuti zimawonjezera chitetezo cha katundu wosunthika. Choncho, unsembe wake akadali analimbikitsa.
