Iye zvino zvave kuwedzera uye zvakajairika kushandisa zvemagetsizvikero zverori. Kana zviri zvekugadzirisa nekugadzirisa zvakazara zvemagetsi marori zvikero / weighbridge, ngatitaurei nezve inotevera informaton seanoyeresa bhiriji rekutengesa:
Iyo yemagetsi rori chiyero inonyanya kuumbwa nezvikamu zvitatu: iyo loadcell, chimiro uye dunhu. Kurongeka kunobva pa1/1500 kusvika 1/10000 kana pasi. Iko kushandiswa kwekaviri yakakosha A / D yekushandura dunhu inogona kusangana nezvinodiwa uye ine zvakanakira simba rakasimba rinopesana nekupindira uye mutengo wakaderera. Mukuitwa kwemitemo yenyika metroology, zvikanganiso zveyerori yemagetsi chiyero pachayo uye zvikanganiso zvekuwedzera mukushandiswa inyaya dzinofanirwa kutariswa nevagadziri nevashandisi.
Kutanga, nzira yekudzikisa zvikanganiso mukugadzira uye kugadzirwa kwemagetsi weighbridge:
1. Guarantee ye loadcell technical zviratidzo
Ndiyo kiyi yekuve nechokwadi chemhando yerori yemagetsi chiyero chekusarudza loadcells ane akasiyana ehunyanzvi zviratidzo anozadzisa zvinodiwa. Linearity, creep, no-load tembiricha coefficient uye senitivity tembiricha coefficient zviratidzo zvakakosha zveloadcells. Kune rimwe nerimwe batch reloadcells, kuongorora sampling uye yakakwirira uye yakaderera tembiricha kuyedza kunofanirwa kuitwa zvinoenderana nechiyero chesampling inodiwa neakakodzera nyika zviyero.
2. Temperature coefficient of electronic truck scale circuit
Theoretical ongororo uye zviedzo zvinoratidza kuti tembiricha yekushisa kwekupokana kweiyo yekupinza amplifier uye kuramba mhinduro zvinhu zvakakosha zvinokanganisa tembiricha yeyemagetsi rori yekunzwa, uye simbi firimu resistor ine tembiricha coefficient ye5 × 10-6. inofanira kusarudzwa. Yepamusoro tembiricha bvunzo dzinofanirwa kuitwa kune yega yega yemagetsi rori chiyero chinogadzirwa. Kune zvimwe zvigadzirwa zvine hushoma hwekunze-kwe-kushivirira tembiricha coefficient, metal film resistors ine tembiricha coefficient isingasviki 25 × 10-6 inogona kushandiswa kubhadhara. Panguva imwechete sekuyedzwa kwekushisa kwepamusoro, chigadzirwa chakaiswa pasi pekuchembera kwekushisa kuti kugadzirise kugadzikana kwechigadzirwa.
3. Non-linear muripo we electronic truck scale
Mumamiriro ezvinhu akanaka, huwandu hwedhijitari hweyerori yemagetsi chiyero mushure mekushandurwa kweanalog-kusvika-dhijitari uye huremu hwakaiswa pachiyero cherori yemagetsi hunofanira kunge hwakatsetseka. Paunenge uchiita calibration chaiyo panguva yekugadzira, shandisa iyo yemukati komputa chirongwa cheimwe-point calibration. Verenga mutserendende pakati penhamba nehuremu zvinoenderana nekwakanaka mutsara wakatwasuka woichengeta mundangariro. Izvi hazvigone kukunda kukanganisa kusiri-mutsara kunogadzirwa ne sensor uye musanganisi. Kushandisa kururamisa-mapoinzi akawanda, kushandisa mitsara yakati wandei kuenzanisa curve zvinonyatso dzikisa chikanganiso chisiri-mutsara pasina kuwedzera mutengo wehardware. Semuyenzaniso, chiyero cherori yemagetsi ine 1/3000 chaiyo inotora 3-point calibration, uye chiyero cherori yemagetsi ine 1/5000 yakarurama inotora 5-point calibration.
