Aikace-aikacen na'urori masu auna zafin jiki a cikin cajin tudu da cajin bindigogi

Na'urori masu auna zafin jiki na NTC suna taka muhimmiyar rawa wajen tabbatar da aminci a cikin cajin tudu da cajin bindigogi. Ana amfani da su da farko don kulawa da zafin jiki na ainihin lokaci da hana kayan aiki fiye da kima, don haka kiyaye aminci da amincin tsarin caji. A ƙasa akwai nazarin takamaiman aikace-aikace da ayyukansu:

1. Yanayin aikace-aikace

• Daidaita Yanayin Zazzabi da Linearization:Halayen NTC marasa kan layi suna buƙatar diyya ta hanyar da'irori (misali, masu rarraba wutar lantarki) ko software algorithms (teburan bincike, daidaiton Steinhart-Hart).
• Zane Mai Ragewa:Aikace-aikace masu ƙarfi na iya amfani da na'urori masu auna firikwensin NTC da yawa don tabbatar da gazawar maki ɗaya ba ta yin lahani ga aminci.
• Hanyoyin Sadarwa da Amsa:Ana watsa bayanan zafin jiki ta hanyar bas na CAN ko siginar analog zuwa Tsarin Gudanar da Baturi (BMS) ko mai sarrafa caji, yana haifar da ka'idojin kariya masu daraja (misali, rage wuta → ƙararrawa → rufewa).

4. Matsayin Masana'antu da Kalubale

• Takaddun Takaddun Tsaro:Yarda da ka'idoji kamar IEC 62196 da UL 2251 don buƙatun kula da zafin jiki.
• Matsanancin Kalubale:Tsayawa a yanayin zafi sama da 120°C ko ƙasa da -40°C na buƙatar ci gaban kayan (misali, fim mai kauri NTC).
• Binciken Laifi:Dole ne tsarin ya gano gazawar NTC (misali, buɗaɗɗen da'irori) don guje wa abubuwan da ke haifar da kariyar karya.

5. Yanayin Gaba

• Haɗin Kai:Haɗuwa tare da algorithms AI don kiyaye tsinkaya (misali, tsinkayar lalata lamba ta hanyar bayanan tarihi).
• Yanayin Ƙarfin Ƙarfi:Kamar yadda caji mai sauri (350kW+) ya zama tartsatsi, NTCs dole ne su inganta saurin amsawa da juriya mai zafi.
• Madadin Magani:Wasu aikace-aikacen na iya ɗaukar PT100 ko firikwensin infrared, amma NTCs sun kasance masu rinjaye saboda ingancin farashi.
