Ukulayishwa ngokugqithisileyo kunye nokugqithwa kwemida yezithuthi zohola wendlela kubangela umonakalo omkhulu kwimigangatho yendlela kwaye kubangela umngcipheko omkhulu weengozi zokhuseleko, umba onzima ngakumbi kwilizwe lethu apho i-70% yezehlo zokhuseleko ezindleleni zibalelwa kukugcwala kwezithuthi kunye nokugqithiswa kwemida. Oku kubangela ilahleko yezoqoqosho ngokuthe ngqo ephantse ibe yi-3 yeebhiliyoni zeerandi, kunye nelahleko evela kumthwalo ogqithisiweyo wezithuthi kunye nokugqithiswa kwemida kwiindlela eziphezulu ezidlula i-30 yezigidigidi zee-RMB ngonyaka. Ke ngoko, kubaluleke kakhulu ukubeka iliso kunye nokubeka iliso kwizithuthi ezigcwele kakhulu koohola bendlela.
Ukuze kulawulwe ukulayisha ngaphezulu kwezithuthi ngaphandle kokuphazamisa ithrafikhi, inkqubo yeWeighting In Moving (WIM) yendlela eguqukayo yokuweyisha iye yavela. Le nkqubo isebenzisa i-piezoelectric quartz sensors ukulinganisa ngokukhawuleza ubunzima besithuthi njengoko izithuthi zidlula phezu kwendlela ngesantya esiphezulu (<120km / h) kwaye ziqalise iikhamera zokubeka esweni ukufota.
Izinzwa ze-quartz ze-Enviko ziyilelwe ngokukodwa i-quartz enexabiso eliphantsi, i-piezoelectric sensors ye-quartz ephezulu yokulinganisa ubungakanani bendlela kunye nokukhusela ibhulorho. Yakhiwe nge-alloy ye-aerospace ye-aluminium ephezulu kunye nomatshini ochanekileyo, ezi zinzwa zinoxinzelelo oluphezulu, ukuqina, ukugoba, ukucheba, kunye nokumelana nomthwalo wokudinwa. Ngonyango lokuguga, uvakalelo lwenzwa luhlala luzinzile amashumi eminyaka.
Ngaphakathi izaliswe nge-elastic insulating paste ekhethekileyo, iinzwa ze-quartz ze-Enviko zigcina uxinzelelo lwangaphakathi oluzinzile, luthintela ngokufanelekileyo umswakama, ngexabiso eliqhelekileyo le-impedance ye-200GΩ.
Ifakwe kwindlela, xa izithuthi zidlula, iivili zicinezela phantsi kwi-sensor ye-bearing surface, ebangela ukuba i-quartz crystals ngaphakathi kwe-sensor ivelise intlawulo ngenxa yempembelelo ye-piezoelectric. Intlawulo ke inyuswe yi-amplifier yentlawulo yangaphandle ibe ngumqondiso we-voltage, ehambelana ngokuthe ngqo noxinzelelo olusetyenziswe kwinzwa. Ngokubala umqondiso woxinzelelo, ubunzima bevili ngalinye kwaye ngoko ke ubunzima obupheleleyo besithuthi bunokufumaneka.
Umlinganiselo we-pressure-charge ratio ye-piezoelectric quartz sensors uhlala ungatshintshi kungakhathaliseki ukuba ubushushu, ixesha, ubungakanani bomthwalo kunye nesantya somthwalo. Ngoko ke, nangona izithuthi zidlula kwindawo yokulinganisa ngesantya esiphezulu, iinzwa ze-quartz zinokugcina ukuchaneka komlinganiselo ophezulu.
Emva kokuba izinzwa ze-WIM zifakwe kwindlela, zichanabeka ekukhanyeni kwelanga, imvula, kunye noxinzelelo lwamavili, nto leyo eyenza ukuba uvavanyo lokuthembeka lubaluleke kakhulu.
Iqondo lobushushu kunye nokufuma kuVavanyo lokuHamba ngeBhayisikile:
Izinzwa ezinendawo ezithweleyo zibekwe kwigumbi lovavanyo lokusingqongileyo kangange-40℃ ukuya kuma-85℃ ubushushu kunye novavanyo lokuhamba ngebhayisekile nokufuma iiyure ezingama-500. Ngethuba lovavanyo, i-impedance ye-insulation ye-sensor kufuneka ingabi ngaphantsi kwe-100GΩ. Emva kovavanyo lokuhamba ngebhayisikile lokushisa kunye nomswakama, iinzwa zifumana ukukhuselwa kwe-insulation kunye novavanyo lomthwalo wokukhathala.
Uvavanyo lomthwalo wokudinwa:
Uvavanyo lokukhathala komthwalo lusebenzisa uxinzelelo lwe-cyclic ye-6000N usebenzisa intloko yentsimbi yentsimbi kunye nobubanzi be-50mm x 50mm kwiindawo ezintathu ekupheleni kwe-sensor kunye nephakathi, kunye nokulayisha kunye nokukhupha kanye ngesibini, imithwalo ye-1,000,000 yokukhathala. Ukwahluka kobuntununtunu bezithuba zovavanyo ezilayishiweyo kufuneka kube <0.5%, kwaye kungabikho monakalo okanye ukudityaniswa kwendawo yokuthwala.
uKhuseleko lwe-Insulation:
Uvavanyo lokukhusela ukugquma lubandakanya ukuntywiliselwa ngokupheleleyo inzwa emanzini, ukuhamba ngebhayisikile phakathi kobushushu begumbi kunye ne-80 ℃, kunye novavanyo olupheleleyo lweeyure ze-1000. Kulo lonke uvavanyo, ukuchasana kwe-insulation ye-sensor akufanele kube ngaphantsi kwe-100GΩ.
Umgca we-piezoelectric quartz sensor signals luphawu olubalulekileyo lweenkqubo zokuvelisa kunye nokuchaneka. Iinzwa ezigqwesileyo ze-quartz ze-piezoelectric ziqinisekisa i-FSO <0.5% kulo lonke uluhlu. Kwi-WIM sensors, impazamo yovakalelo kuyo nayiphi na indawo kunye nobude be-sensor kufuneka ingadluli kwi-2%. Ke ngoko, izixhobo zovavanyo ezingqongqo nezichanekileyo ziyimfuneko kwimveliso yeenzwa.
Ijika lophawu lokulayisha lilinganisa i-force-charge curve kunye ne-linearity error (%FSO) ngexesha lokulayisha kunye nokukhupha kunye nobubanzi be-100mm yokulayisha intloko esetyenziswe kwinzwa kuyo nayiphi na indawo.
Ijika lophawu lwe-flatness lilinganisa ixabiso lovakalelo ngexesha lokulayisha ecaleni kwendlela yobude benzwa (ngaphandle kwendawo yokuthwala) usebenzisa i-50mm ububanzi bentloko yoxinzelelo kunye ne-force ye-8000N, kunye namaxabiso ovakalelo afunyenwe kwindawo nganye yovavanyo lokulayisha esetyenziselwa ukubala umqondiso. Ukuthe tyaba ecaleni kwendlela yobude boluvo.
Nangona kunjalo, abanye abavelisi basebenzisa ngamabomu i-250mm ububanzi bentloko yokulayisha uxinzelelo lovavanyo lwe-flatness yesignali, elilingana namaxesha e-5 e-avareji ye-curve yeempawu, okubangelwa ukuchaneka kobuxoki kwe-1%. Izibonakaliso kuphela ezifunyenwe ngokulayisha imilinganiselo usebenzisa i-50mm ububanzi bentloko yoxinzelelo lwentloko inokubonisa ngokwenene ukuchaneka kunye nomgangatho wenzwa.
