Kuchulutsa ndi kupitirira malire a magalimoto a pamsewu kumayambitsa kuwonongeka kwakukulu kwa misewu ndikuyika ngozi zoopsa za chitetezo, nkhani yaikulu kwambiri m'dziko lathu momwe 70% ya ngozi zapamsewu zimachitika chifukwa cha kuchuluka kwa magalimoto ndi kupitirira malire. Izi zimabweretsa kuwonongeka kwachuma kwapafupifupi 3 biliyoni RMB, ndikutayika kwa magalimoto odzaza kwambiri komanso malire opitilira misewu yayikulu yopitilira 30 biliyoni RMB pachaka. Chifukwa chake, ndikofunikira kwambiri kuyang'anira ndi kuyang'anira magalimoto odzaza kwambiri m'misewu yayikulu.
Pofuna kuwongolera kuchuluka kwa magalimoto popanda kusokoneza kuchuluka kwa magalimoto, njira yoyezera misewu yayikulu ya Weighting In Moving (WIM) yatulukira. Dongosololi limagwiritsa ntchito masensa a piezoelectric quartz kuti ayese msanga kulemera kwa galimoto pamene magalimoto amadutsa pamsewu pa liwiro lapamwamba (<120km/h) ndi kuyambitsa makamera oyang'anira kujambula.
Masensa a Enviko quartz adapangidwa mwapadera kuti akhale otsika mtengo, ochita bwino kwambiri a piezoelectric quartz sensors kuti azitha kuyeza pamsewu waukulu komanso kuteteza mlatho. Zopangidwa ndi aluminiyamu yamphamvu kwambiri yamlengalenga komanso makina olondola, masensawa amakhala ndi kuponderezana kwakukulu, kolimba, kupindika, kumeta ubweya, komanso kukana kutopa. Kupyolera mu chithandizo cha ukalamba, kukhudzidwa kwa sensa kumakhalabe kokhazikika kwa zaka zambiri.
Mkati wodzazidwa ndi phala wapadera zotanuka insulating, Enviko quartz masensa amakhala khola mkati kuthamanga, bwino kutsekereza chinyezi, ndi mmene kutchinjiriza Impedans mtengo wa 200GΩ.
Ophatikizidwa mumsewu, magalimoto akamadutsa, mawilo amakankhira pansi pamtunda wa sensa, zomwe zimapangitsa kuti makristasi a quartz mkati mwa sensa apange ndalama chifukwa cha piezoelectric effect. Mlanduwo umakulitsidwa ndi amplifier yakunja yamagetsi mu siginecha yamagetsi, yomwe imagwirizana mwachindunji ndi kukakamiza komwe kumagwiritsidwa ntchito ku sensa. Powerengera chizindikiro chokakamiza, kulemera kwa gudumu lililonse ndipo motero kulemera kwa galimoto kungapezeke.
Kuthamanga kwa chiŵerengero cha ma sensor a piezoelectric quartz kumakhalabe kosasintha mosasamala kanthu za kutentha, nthawi, kukula kwa katundu, ndi liwiro la katundu. Chifukwa chake, ngakhale magalimoto akadutsa pamtunda woyezera pa liwiro lalikulu, masensa a quartz amatha kusunga muyeso wolondola kwambiri.
Masensa a WIM akayikidwa mumsewu, amakumana ndi kuwala kwa dzuwa, mvula, komanso kuthamanga kwa magudumu, zomwe zimapangitsa kuyesa kudalirika kukhala kofunikira.
Mayeso a Kutentha ndi Chinyezi cha Panjinga:
Zomverera zokhala ndi malo onyamula zimayikidwa muchipinda choyesera zachilengedwe kwa -40 ℃ mpaka 85 ℃ kutentha ndi kuyezetsa njinga kwa chinyezi kwa maola 500. Pakuyesa, kutsekereza kwa masensa kuyenera kukhala kotsika kuposa 100GΩ. Pambuyo pakuyesa kwapanjinga kwa kutentha ndi chinyezi, masensa amakumana ndi chitetezo chotchinjiriza ndikuyesa kutopa.
Kutopa Katundu Mayeso:
Kuyesa kutopa kwa katundu kumagwiritsa ntchito kuthamanga kwa cyclic kwa 6000N pogwiritsa ntchito chitsulo chopondereza mutu ndi m'lifupi mwake 50mm x 50mm pa malo atatu kumapeto kwa sensa ndi pakati, ndikutsitsa ndi kutsitsa kamodzi pa sekondi imodzi, yokwana 1,000,000 kutopa. Kusiyanasiyana kwamphamvu kwa malo oyesedwa odzaza kuyenera kukhala <0.5%, ndipo pasakhale kuwonongeka kapena kutsekeka kwa malo onyamula.
Chitetezo cha Insulation:
Kuyesa kwachitetezo cha insulation kumaphatikizapo kumizidwa kwathunthu m'madzi, kuyendetsa njinga pakati pa kutentha kwa chipinda ndi 80 ℃, ndikuyesa kwathunthu kwa maola 1000. Pakuyesa konse, kukana kwa sensor sikuyenera kukhala kotsika kuposa 100GΩ.
Mzere wa piezoelectric quartz sensor sensor ndi chizindikiro chofunikira cha njira zopangira ndi zolondola. Masensa abwino kwambiri a piezoelectric quartz amatsimikizira FSO <0.5% pamitundu yonse. Kwa masensa a WIM, cholakwika cha sensitivity pamalo aliwonse kutalika kwa sensor sichiyenera kupitirira 2%. Chifukwa chake, zida zoyeserera zowoneka bwino komanso zolondola ndizofunikira pakupanga sensa.
Mapiritsi amtundu wonyamula amayesa kukakamiza-charge curve ndi linearity error (% FSO) panthawi yotsitsa ndi kutsitsa ndi m'lifupi mwa mutu wa 100mm wotsegulira womwe umagwiritsidwa ntchito pa sensa pamalo aliwonse.
Chizindikiro cha flatness khalidwe pamapindikira amayesa kukhudzika kwamphamvu pakukweza mbali yautali wa sensa (popanda kunyamula pamwamba) pogwiritsa ntchito 50mm m'lifupi kukakamiza mutu ndi mphamvu ya 8000N, yokhala ndi zomverera zomwe zimapezeka pamalo aliwonse oyeserera omwe amagwiritsidwa ntchito kuwerengera chizindikiro. flatness motsatira kutalika kwa sensa.
Komabe, ena opanga dala amagwiritsa ntchito dala 250mm m'lifupi pokweza mutu woponderezedwa poyesa kukhazikika kwa chizindikiro, chofanana ndi kuchulukitsa ka 5 kwa mapindikidwe ake, zomwe zimapangitsa kuti 1% ikhale yolondola. Zizindikiro zokha zomwe zimapezedwa pokweza miyeso pogwiritsa ntchito mutu wa 50mm m'lifupi mwake zimatha kuwonetsa kulondola komanso mtundu wa sensor.
