Kulawar Hasashen da Motoci

Riba:

• Ability don bayyana yanayin bas ɗin CAN, telematics da na'urar firikwensin firikwensin da ƙimar kulawar tsinkaya a duk tsawon rayuwar jirgin ruwa / abin hawa.
• Ikon kafa tsarin aiki na hankali na wucin gadi a cikin gano anomaly, ƙimar rayuwa mai amfani (RUL) da fassarar lambar kuskure
• Ikon tabbatar da fitowar ƙorafin tsinkaya ta hanyar daidaita farashin ƙararrawa na ƙarya, taga tabbatarwa da gefen aminci

Kuna iya kula da abin hawa ko jirgin ruwa (motar kasuwanci, babbar mota, bas, rukunin kayan gini) ta hanyoyi uku. Gyaran gyarawa: gyara shi idan ya karye (mafi tsada saboda yana kawo gazawar kwatsam da rufewa). Kulawa na rigakafi: maye gurbin kowane kilomita 15,000 (aminci amma ɓatacce, saboda ku ma jefar da ɓangaren mai kyau). Kulawa da tsinkaya: duba bayanan kuma kuyi hasashen "wannan bangare zai gaza bayan kusan kilomita 2,000" kuma ya shiga tsakani a daidai lokacin. Hankali na wucin gadi shine fasaha da ke ba da damar kiyaye tsinkaya. A cikin wannan rukunin, za mu ga yadda bayanan abin hawa ke gudana, yadda aka kafa samfuran kulawa da tsinkaya, da yadda ake amfani da waɗannan tsinkaya cikin aminci.

Daga ina bayanan abin hawa ke fitowa? CAN, OBD da telematics

Kayan aiki koyaushe suna samar da bayanai:

• CAN bas (Controller Area Network): Ita ce cibiyar sadarwa ta ciki inda na'urorin sarrafa lantarki (ECU) a cikin abin hawa suke magana da juna. Daruruwan sigina kamar saurin injin, gudu, zafin jiki, kwararar matsayin gas daga nan.
• OBD-II (Akan-Board Diagnostics): Daidaitaccen tashar jiragen ruwa; Yana ba ku damar karanta lambobin kuskure da ake kira DTCs (Lambar Matsala na Ganewa, misali P0301 = skip na silinda na farko).
• Telematics / telemetry: Motar tana aika wannan bayanan ba tare da waya ba (ta hanyar tsarin katin SIM) zuwa tsakiya. Ana lura da matsayi, halin tuƙi, yanayin injin nesa.

Wannan bayanan yawanci jerin lokuta ne: jerin ƙimar da aka auna a ƙayyadaddun tazara (misali, kowane daƙiƙa). Wannan shine albarkatun kasa na kiyaye tsinkaya.

Hankali: Wuri, halin tuƙi da VIN (lambar chassis) bayanai ne na sirri/m. Rashin ɓoyewa, rage bayanai da bin KVKK/GDPR suna da mahimmanci yayin aiki tare da na'urar wayar hannu (bayanan bayanai a cikin naúrar 10). Kar a aika da ɗanyen VIN zuwa kayan aikin AI na gabaɗaya.

Manyan ayyuka guda uku na kiyaye tsinkaya

1. Ganewar anomaly: Ɗaukar karkata daga halin al'ada. Alal misali, zafin jiki na turbo yana ci gaba da kasancewa 15 ° C fiye da yadda ake tsammani a karkashin irin wannan yanayi. Samfurin ya koyi "al'ada", yana nuna karkatacciyar hanya.
2. Ƙimar Rayuwa Mai Amfani (RUL): Ƙididdigar kiyasin ragowar lokacin aiki/nisa na kayan aiki har zuwa gazawa. "Wannan kama yana kaiwa ga lalacewa mai mahimmanci bayan kusan kilomita 3,500."
3. Rarraba kuskure / tushen tushen: Hasashen wane nau'in laifin ya samo asali daga tsarin firikwensin da hada shi da DTCs.

Mataki-mataki: tsarin aiki mai tsinkaya

1. Bayyana tambayar kasuwanci. Me muke tsinkaya (wanne bangare, wanne rashin aiki)? Yaya nisa a gaba ana buƙatar faɗakarwa da wuri?
2. Tattara da daidaita bayanai. Tamburan lokaci na firikwensin daban-daban dole ne a daidaita su, dole ne raka'a su kasance masu daidaituwa.
3. Tag / bayanin taron. Alama kurakuran da suka faru a baya; samfurin yana koya daga waɗannan. Idan babu lakabin, juya zuwa gano abin da ba shi da kyau.
4. Injiniyan fasali. Cire fasalulluka masu ma'ana daga siginar ɗanyen aiki: matsakaita motsi, abubuwan mitar girgiza, ƙimar haɓakar zafin jiki.
5. Samfurin gini da tabbatarwa. Kula da bambance-bambancen da suka gabata / na gaba a cikin jerin lokaci (haɗarin zubewar bayanai!).
6. Matsakaicin ƙararrawa da dabaru. Yaushe ƙararrawar "cirewa da ake buƙata" zata bayyana?
7. Fitowa da saka idanu. Bibiyar daidaiton ƙararrawa; rage ƙimar ƙararrawa na ƙarya.

Tukwici: Kada ku yi amfani da horo na gaba lokacin kimanta samfurin a cikin jerin lokaci. Ba za a iya sanin sifa kamar "matsakaicin mintuna 5 masu zuwa" a lokacin tsinkaya; wannan ƙwanƙwasa bayanai ne kuma yana sa ƙirar ta yi girma a cikin lab amma mara amfani a fagen.

Amfani da ƙimar RUL daidai

Kodayake RUL na iya zama kamar lamba ɗaya, haƙiƙa ƙima ce kuma tana ɗauke da rashin tabbas. Daidaitaccen amfani:

• Gabatarwa tare da kewayon rashin tabbas. "3,000-4,200 km (80% amincewa)" maimakon "3,500 km". An yi tsarin kulawa bisa ga mafi munin yanayi.
