Kuremerwa uye kudarika miganho yemotokari dzemumigwagwa inokonzera kukuvadzwa kukuru kwenzvimbo dzemigwagwa uye kunoisa njodzi huru yetsaona dzekuchengetedza, inyaya yakakomba munyika medu umo 70% yezviitiko zvekuchengetedza mumigwagwa zvinokonzerwa nekuremerwa kwemotokari uye kudarika miganho. Izvi zvinoguma nekurasikirwa kwakananga kwehupfumi kweanoda kusvika 3 bhiriyoni RMB, nekurasikirwa kubva mukuremerwa kwemotokari uye kudarika miganho mumigwagwa mikuru inodarika 30 bhiriyoni RMB pagore. Nekudaro, zvakakosha zvakanyanya kutarisa uye kutarisa mota dzakaremerwa mumigwagwa mikuru.
Kuti zvigadzirise kuwandisa kwemotokari pasina kukanganisa traffic, chirongwa cheWeighting In Moving (WIM) chemagetsi chehuremu chakabuda. Iyi sisitimu inoshandisa piezoelectric quartz sensors kuti ikurumidze kuyera huremu hwemotokari sezvo mota dzichipfuura pamusoro pemugwagwa nekumhanya kwakanyanya (<120km/h) uye kukonzeresa makamera ekutarisa kutora mifananidzo.
Enviko quartz sensors dzakagadzirirwa zvakachipa-mutengo wakaderera, yakakwirira-inoshanda piezoelectric quartz sensors yemugwagwa mukuru wehuremu uye kudzivirira bhiriji. Yakagadzirwa neakakwira-simba aerospace aluminium alloy uye chaiyo machining, aya masensa ane yakakwirira compressive, tensile, kukotama, shear, uye kuneta mutoro kuramba. Kuburikidza nekurapa kwekuchembera, sensor senitivity inoramba yakagadzikana kwemakumi emakore.
Mukati yakazadzwa neyakasarudzika elastic insulating paste, Enviko quartz sensors inochengetedza yakagadzikana yemukati kudzvanywa, inonyatso kuvharira unyoro, ine yakajairika insulation impedance kukosha kwe200GΩ.
Yakamisikidzwa mumugwagwa wepamusoro, kana mota dzichipfuura, mavhiri anotsikirira pasi pesensor inotakura nzvimbo, zvichiita kuti makristasi equartz ari mukati me sensor abudise kuchaja nekuda kweiyo piezoelectric athari. Iyo yekuchaja inozowedzerwa neyekunze yekuchaja amplifier muchiratidzo chevoltage, iyo yakanangana nekudzvanywa kunoshandiswa kune sensor. Nekuverenga chiratidzo chekumanikidza, huremu hwevhiri rega rega uye nekudaro huremu hwese hwemotokari hunogona kuwanikwa.
Iyo yekumanikidza-chaji reshiyo hunhu hwepiezoelectric quartz sensors inoramba isina kuchinjika zvisinei nekupisa, nguva, saizi yemutoro, uye kumhanya kwemutoro. Naizvozvo, kunyangwe mota dzichipfuura pamusoro pekuyeresa nekumhanya kwakanyanya, ma sensors e quartz anogona kuchengetedza yakakwirira kuyerwa kwechiyero.
Mushure mekunge ma sensors eWIM akaiswa munzira, anovhenekwa nechiedza chezuva, mvura, uye vhiri remavhiri, zvichiita kuti kuyedzwa kwekuvimbika kuve kwakakosha.
Tembiricha uye Humidity Cycling Test:
Masensore ane nzvimbo inotakura anoiswa mukamuri yekuyedza yezvakatipoteredza kwe -40 ℃ kusvika 85 ℃ tembiricha uye humidity bhasikoro bvunzo kwemaawa mazana mashanu. Munguva yekuyedzwa, iyo yekuvharisa impedance ye sensors haifanire kunge yakaderera pane 100GΩ. Mushure mekushisa uye humidity bhasikoro bvunzo, ma sensors anochengeterwa kudzivirira uye kuneta mutoro kuyedzwa.
Kuneta Load Test:
Muedzo wekuneta kwemutoro unoshandisa cyclic pressure ye6000N uchishandisa simbi yekumanikidza musoro ine hupamhi hwe50mm x 50mm panzvimbo nhatu pamagumo e sensor uye nepakati, nekurodha nekuburitsa kamwe pasekondi, inokwana zviuru gumi zvekuneta. Kusiyana kwekunzwa kwenzvimbo dzakaremerwa dzebvunzo dzinofanirwa kunge dziri <0.5%, uye hapafanirwe kuve nekukuvadzwa kana kuvharika kweiyo inotakura nzvimbo.
Insulation Dziviriro:
Iyo yekudzivirira yekudzivirira bvunzo inosanganisira kunyudza zvizere sensor mumvura, kuchovha pakati pekamuri tembiricha uye 80 ℃, ine yakazara bvunzo yenguva ye1000 maawa. Muyedzo yese yese, iyo yekuvharisa ye sensor haifanire kunge yakaderera pane 100GΩ.
Iyo mutsara wepiezoelectric quartz sensor masaini chiratidzo chakakosha chekugadzira maitiro uye huchokwadi. Yakanakisa piezoelectric quartz sensors inovimbisa FSO <0.5% mukati mese siyana. Kune WIM sensors, kukanganisa kwekunzwa pane chero chinzvimbo pamwe nehurefu hwe sensor haifanire kudarika 2%. Naizvozvo, yakasimba uye yakarurama senitivity yekuongorora michina yakakosha pakugadzira sensor.
Iyo yekurodha maitiro curve inoyera iyo yekumanikidza-chaji curve uye mutsara kukanganisa (% FSO) panguva yekurodha uye kurodha nehupamhi hwe100mm yekurodha musoro wakaiswa kune sensor pane chero chinzvimbo.
Chiratidzo che flatness hunhu curve inoyera kukosha kwekunzwa panguva yekurodha pamwe nekureba kutungamira kwe sensor (isina iyo inotakura nzvimbo) uchishandisa 50mm hupamhi hwekumanikidza musoro nechisimba che 8000N, ine hunhu hwekunzwa hunowanikwa pane imwe neimwe yekurodha test point inoshandiswa kuverenga chiratidzo. flatness pamwe nekureba kutungamira kwe sensor.
Nekudaro, vamwe vagadziri vanoshandisa nemaune 250mm hupamhi hwekuremedza kumanikidza musoro wechiratidzo chekuyedza kubhururuka, zvakaenzana nekashanu kuenzana kweavhareji curve, zvichikonzera kukanganisa kwechokwadi kwe1%. Zviratidzo chete zvakawanikwa nekurodha zviyero uchishandisa 50mm hupamhi hwekumanikidza musoro musoro unogona kunyatsoratidza kurongeka uye kunaka kwe sensor.
