tayala pressure sensor
Momwe ma sensa a tayala amagwirira ntchito
zikugwira
kugawana
Pali mfundo zitatu za sensa ya tayala: 1. Kuwunika kwa tayala molunjika Chida choyang'anira kuthamanga kwa tayala chimagwiritsa ntchito kachipangizo kamene kamayikidwa mu tayala iliyonse kuti ayese mwachindunji kuthamanga kwa tayala, ndipo amagwiritsa ntchito transmitter opanda zingwe kuti atumize kupanikizika kuchokera mkati mwa tayala. .ku gawo lapakati lolandila, ndiyeno wonetsani deta ya kuthamanga kwa tayala lililonse.Pamene kuthamanga kwa tayala kumakhala kochepa kwambiri kapena kutayikira
1 Momwe masensa akuthamanga kwa tayala amagwirira ntchito
Pali mfundo zitatu za sensor ya tayala:
1. Kuwunika kwapang'onopang'ono kwa tayala Kuwunika kwa tayala mwachindunji kumagwiritsa ntchito mphamvu yamagetsi yomwe imayikidwa mu tayala iliyonse kuti iwonetsetse kuthamanga kwa tayala, ndipo imagwiritsa ntchito transmitter yopanda zingwe kuti itumize uthenga wopanikizika kuchokera mkati mwa tayala kupita ku gawo lapakati lolandira, ndipo Kenako Amawonetsa kuchuluka kwa mpweya wa tayala lililonse.Kuthamanga kwa tayala kukakhala kochepa kwambiri kapena kutayikira, makinawo amadzidzimutsa;
2. Kuwunika kwapang'onopang'ono kwa matayala Mfundo yogwira ntchito yowunika kuthamanga kwa tayala ndi: pamene kuthamanga kwa mpweya wa tayala kumachepa, kulemera kwa galimotoyo kumapangitsa kuti gudumu likhale laling'ono, zomwe zimapangitsa kuti liwiro lake likhale lofulumira kuposa mawilo ena.Poyerekeza kusiyana kwa liwiro pakati pa matayala, cholinga chowunika kuthamanga kwa tayala chimakwaniritsidwa.Alamu ya tayala yosadziwika bwino imayang'anitsitsa kuthamanga kwa mpweya powerengera utali wozungulira wa tayala;
3. Mitundu iwiri ya kuwunika kuthamanga kwa tayala Zida ziwirizi zowunikira kuthamanga kwa tayala zili ndi zabwino ndi zovuta zake.Chipangizo choyang'anira kuthamanga kwa tayala mwachindunji chingapereke ntchito yapamwamba kwambiri, kuyeza kuthamanga kwenikweni kwanthawi yomweyo mkati mwa tayala iliyonse nthawi iliyonse, ndipo n'zosavuta kuzindikira tayala lolakwika.Mtengo wosalunjika ndi wotsika kwambiri, ndipo magalimoto omwe ali ndi 4-wheel ABS (1 wheel speed sensor pa tayala) amangofunika kukweza pulogalamuyo.Komabe, chipangizo choyang'anira kuthamanga kwa tayala chosalunjika sichinali cholondola ngati chiwongolero chachindunji, sichingathe kudziwa tayala yolakwika, ndipo kuwongolera kwadongosolo kumakhala kovuta kwambiri, nthawi zina dongosolo silingagwire ntchito bwino, monga chitsulo chofananira 2. kuthamanga kwa tayala ndi otsika Nthawi.
2 Kodi batire ya tyre pressure sensor imatha nthawi yayitali bwanji?
Mabatire a sensor ya tayala amatha kukhala zaka 2 mpaka 3:
1. Sensa yowunikira kuthamanga kwa tayala imatha kusintha batire palokha.Kuwunika kuthamanga kwa matayala kwakhala kofunikira kwambiri pamagetsi pamagetsi kwa eni magalimoto.Pakadali pano, zida zambiri zowunikira kupanikizika kwa matayala zili ndi masensa akunja, ndipo batire ya CR1632 nthawi zambiri imayikidwa mkati mwa sensa yakunja.Palibe vuto kwa zaka 2-3 zogwiritsidwa ntchito mwachizolowezi, ndi zaka 2 Batire imatha pakapita nthawi yayitali;
2. Zomwe zili mu gawo la tayala la TPMS ndi MEMS pressure sensor, sensor sensor, voltage sensor, accelerometer, microcontroller, RF circuit, antenna, LF interface, oscillator ndi betri.Opanga magalimoto amafunikira mabatire okhala ndi TPMS mwachindunji kuti azikhala zaka zopitilira khumi.Batire iyenera kukhala ndi kutentha kwa -40 ° C mpaka 125 ° C, kukhala yopepuka kulemera, yaying'ono kukula ndi mphamvu yaikulu;
3. Chifukwa cha zoperewerazi, maselo a batani nthawi zambiri amasankhidwa m'malo mwa maselo akuluakulu.Batire yatsopano ya batani imatha kufika ku mphamvu ya 550mAh ndipo imalemera magalamu 6.8 okha.Kuwonjezera pa mabatire, kuti akwaniritse ntchito ya moyo wa zaka zoposa khumi, zigawozo ziyenera kukhala ndi ntchito zophatikizika pamene zikusunga mphamvu zochepa;
4. Mtundu uwu wa mankhwala ophatikizika umaphatikizapo kupanikizika kwa mphamvu, kutentha kwa kutentha, mphamvu yamagetsi, accelerometer, mawonekedwe a LF, microcontroller ndi oscillator mu chigawo chimodzi.Dongosolo lathunthu la matayala lili ndi zigawo zitatu zokha - SP30, RF transmitter chip (monga Infineon's TDK510xF) ndi batri.CHISONYEZO CHATHU :
