Ho jara le ho feta meeli ea makoloi a litsela tse kholo e baka tšenyo e kholo holim'a litsela 'me e beha kotsi e kholo ea likotsi tsa polokeho, e leng taba e tebileng haholo naheng ea rona moo 70% ea diketsahalo tsa polokeho mebileng e amahanngoang le ho palama ha likoloi le ho tlola meeli. Sena se fella ka tahlehelo e tobileng ea moruo e ka bang limilione tse likete tse 3 tsa RMB, ka tahlehelo e tsoang ho ho palamisa likoloi le ho feta meeli litseleng tse kholo tse fetang RMB tse limilione tse likete tse 30 selemo le selemo. Ka hona, ho bohlokoa haholo ho beha leihlo le ho beha leihlo likoloi tse tletseng litseleng tse kholo.

E le ho laola boima ba makoloi ntle le ho sitisa sephethephethe, ho hlahile sekema sa boima ba tsela e kholo ea Weighting In Moving (WIM). Tsamaiso ena e sebelisa li-piezoelectric quartz sensors ho lekanya ka potlako boima ba koloi ha likoloi li feta holim'a tsela ka lebelo le phahameng (<120km / h) le ho kenya lik'hamera tsa ho shebella bakeng sa ho nka lifoto.

Li-sensor tsa quartz tsa Enviko li etselitsoe ka ho khetheha li-sensor tsa quartz tsa piezoelectric tse theko e tlase, tse sebetsang hantle bakeng sa boima ba 'mila o matla le tšireletso ea borokho. E hahiloe ka alloy ea aluminium ea matla a holimo le machining a nepahetseng, li-sensor tsena li na le khatello e phahameng ea khatello, ho tsieleha, ho kobeha, ho kuta le moroalo oa mokhathala. Ka phekolo ea botsofali, kutloisiso ea sensor e lula e tsitsitse ka lilemo tse mashome.

Ka hare ho tlatsitsoe ka pente e khethehileng ea elastic insulating, Enviko quartz sensors e boloka khatello e tsitsitseng ea ka hare, ka katleho e thibela mongobo, ka mokhoa o tloaelehileng oa ho itšireletsa oa 200GΩ.

E kenngoe ka holim'a tsela, ha likoloi li feta, mabili a hatella holim'a sebaka sa ho beleha ha sensor, e leng se etsang hore likristale tsa quartz ka hare ho sensor li hlahise tefiso ka lebaka la phello ea piezoelectric. Tefiso e ntan'o phahamisoa ke amplifier ea ka ntle ea tefiso ho letšoao la motlakase, le lekanang ka ho toba le khatello e sebelisoang ho sensor. Ka ho bala letšoao la khatello, boima ba lebili le leng le le leng 'me kahoo boima bohle ba koloi bo ka fumanoa.

Khatello-charge tšobotsi tšobotsi ea piezoelectric quartz sensors e lula e sa fetohe ho sa tsotellehe mocheso, nako, boholo ba mojaro, le lebelo la mojaro. Ka hona, esita le ha likoloi li feta holim'a sebaka sa ho lekanya ka lebelo le phahameng, li-sensor tsa quartz li ka boloka ho nepahala ha tekanyo e phahameng.

Kamora hore li-sensor tsa WIM li kenngoe tseleng, li pepesetsoa khanya ea letsatsi, pula le khatello ea mabili, e leng se etsang hore tlhahlobo ea ts'epo e be ea bohlokoa.

Teko ea Libaesekele tsa Mocheso le Mongobo:

Li-sensor tse nang le bokaholimo ba lintho li behiloe ka phaposing ea tlhahlobo ea tikoloho bakeng sa -40 ℃ ho isa ho 85 ℃ liteko tsa mocheso le mongobo oa libaesekele bakeng sa lihora tse 500. Nakong ea tlhahlobo, ho kenella ha li-sensor ha hoa lokela ho ba tlase ho 100GΩ. Ka mor'a tlhahlobo ea libaesekele tsa mocheso le mongobo, li-sensor li kena ts'ireletso ea ho itšireletsa le tlhahlobo ea mokhathala.

Teko ea Moroalo oa Mokhathala:

Teko ea mokhathala oa mojaro e sebetsa khatello ea cyclic ea 6000N e sebelisang hlooho ea khatello ea tšepe e nang le bophara ba 50mm x 50mm libakeng tse tharo lipheletsong tsa sensor le bohareng, ka ho laolla le ho laolla hang ka motsotsoana, e leng kakaretso ea meroalo ea mokhathala oa 1,000,000. Phapang ea kutlo ea maemo a liteko tse jarollotsoeng e tlameha ho ba <0.5%, 'me ha hoa lokela ho ba le ts'enyehelo kapa ts'ebetso ea bokaholimo ba ho beha.

Tšireletso ea Insulation:

Teko ea ts'ireletso ea insulation e kenyelletsa ho qoelisa sensor ka metsing, ho palama baesekele lipakeng tsa mocheso oa kamore le 80 ℃, ka nako ea tlhahlobo ea lihora tse 1000. Ho pholletsa le teko eohle, ho hanyetsa ha sensor ea sensor ha hoa lokela ho ba tlase ho 100GΩ.

Boleng ba matšoao a sensor ea quartz ea piezoelectric ke sesupo sa bohlokoa sa lits'ebetso tsa tlhahiso le ho nepahala. Li-sensor tse ntle tsa quartz tsa piezoelectric li netefatsa FSO <0.5% ho pholletsa le mefuta eohle. Bakeng sa li-sensor tsa WIM, phoso ea kutlo sebakeng sefe kapa sefe ka bolelele ba sensor ha ea lokela ho feta 2%. Ka hona, lisebelisoa tse thata le tse nepahetseng tsa tlhahlobo ea kutlo li bohlokoa bakeng sa tlhahiso ea li-sensor.

The loading character curve e lekanya curve-charge curve le linearity error (% FSO) nakong ea ho kenya le ho laolla ka bophara ba 100mm ho kenya hlooho e sebelisoang ho sensor sebakeng leha e le sefe.

Leha ho le joalo, bahlahisi ba bang ba sebelisa ka boomo hlooho ea khatello ea bophara ba 250mm bakeng sa tlhahlobo ea matšoao a bataletseng, e lekanang le makhetlo a 5 ka karolelano ea sekhahla sa sebopeho, se hlahisang ho nepahala ha 1%. Ke matšoao feela a fumanoang ka ho kenya litekanyo ho sebelisa hlooho ea khatello ea bophara ba 50mm e ka bontšang ho nepahala le boleng ba sensor.
