Maumbirwo ehukuru hwerori uye nzira dzekuderedza kushivirira

Iye zvino zvave kunyanya kushandiswa kwemagetsizviyero zveroriNezvekugadzirisa nekugadzirisa zvese zvema "electronic truck scales/weighbridge", ngatitaurei nezveruzivo runotevera semutengesi we "weighbridge":

Chikero chemotokari yemagetsi chinoumbwa nezvikamu zvitatu: loadcell, chimiro uye circuit. Kurongeka kwacho kunobva pa1/1500 kusvika 1/10000 kana pasi. Kushandiswa kwe double integral A/D conversion circuit kunogona kusangana nezvinodiwa zvekururama uye kune mabhenefiti ekudzivirira kukanganiswa kwakasimba uye mutengo wakaderera. Mukushandisa mitemo yenyika ye metrology, zvikanganiso zve electronic truck scale pachayo uye zvimwe zvikanganiso zviri kushandiswa inyaya dzinofanirwa kutariswa nevagadziri nevashandisi.

Chekutanga, nzira yekuderedza zvikanganiso mukugadzirwa uye kugadzirwa kweweighbridge yemagetsi:

1. Vimbiso yezviratidzo zvehunyanzvi zve loadcell

Ndiyo kiyi yekuona kuti masero emagetsi emota akagadzirwa zvakanaka kuti asarudze masero ane zviratidzo zvakasiyana-siyana zvehunyanzvi zvinosangana nezvinodiwa nemazvo. Linearity, creep, no-load temperature coefficient uye sensitivity temperature coefficient zviratidzo zvakakosha zvemasero emota. Paboka rega rega remasero emota, kuongororwa kwemasampuli uye kuyedzwa kwekupisa kwakakwira nekwakaderera kunofanirwa kuitwa zvichienderana nehuwandu hwesampuli hunodiwa nemitemo yenyika yakakodzera.

2. Kupisa kwakakwana kwedunhu remagetsi remarori

Kuongorora kwedzidziso uye kuyedza zvinoratidza kuti chiyero chekupisa chekudzivirira kwekupinda kweamplifier yekupinda uye chiyero chemhinduro zvinhu zvakakosha zvinokanganisa chiyero chekupisa chechiyero chemagetsi, uye chinodzivirira firimu resimbi chine chiyero chekupisa che5×10-6 chinofanira kusarudzwa. Miedzo yekupisa kwakanyanya inofanirwa kuitwa kune yega yega electronic truck scale inogadzirwa. Kune zvimwe zvigadzirwa zvine chiyero chidiki chekupisa chisina kushivirira, zvinodzivirira firimu resimbi zvine chiyero chekupisa chisingasviki 25×10-6 zvinogona kushandiswa kutsiva. Panguva imwe chete nekuyedzwa kwekupisa kwakanyanya, chigadzirwa chakaiswa mukukwegura kwekupisa kuti chivandudze kugadzikana kwechigadzirwa.

3. Kubhadhara kusingaenzaniswi kwehukuru hwerori yemagetsi

Mumamiriro ezvinhu akanaka, huwandu hwedhijitari hwechikero chemotokari yemagetsi mushure mekushandurwa kweanalog-to-digital uye huremu hunoiswa pachikero chemotokari yemagetsi hunofanira kunge hwakatsetseka. Paunenge uchiita calibration yekururamisa panguva yekugadzira, shandisa purogiramu yekombuta yemukati kuti utarise nzvimbo imwe chete. Verenga mutserendende uri pakati penhamba nehuremu zvichienderana nemutsetse wakatwasuka wakakodzera uye uuchengete mundangariro. Izvi hazvigone kukunda chikanganiso chisina kutsetseka chinogadzirwa ne sensor ne integrator. Uchishandisa multi-point correction, kushandisa multi-straight lines kuti ufungidzire curve zvinobudirira zvinoderedza chikanganiso chisina kutsetseka pasina kuwedzera mutengo wehardware. Semuenzaniso, chikero chemotokari yemagetsi chine 1/3000 accuracy chinoshandisa 3-point calibration, uye chikero chemotokari yemagetsi chine 1/5000 accuracy chinoshandisa 5-point calibration.
