Gwajin Sensor na Quartz kafin shigarwa a Weigh-In-Motion

Weigh-In-Motion (WIM) fasaha ce da ke auna nauyin abin hawa yayin da suke cikin motsi, wanda ke kawar da bukatar ababen hawa su tsaya. Yana amfani da na'urori masu auna firikwensin da aka sanya a ƙarƙashin saman hanya don gano sauye-sauyen matsa lamba yayin da motocin ke wucewa a kansu, suna ba da bayanan ainihin lokacin kan nauyi, nauyin axle, da sauri. Ana amfani da tsarin WIM sosai a cikin sarrafa zirga-zirga, tilastawa yin aiki da yawa, da dabaru don inganta inganci da aminci.

WIM yana ba da fa'idodi masu mahimmanci, gami da rage cunkoson ababen hawa, sa ido na ainihin lokaci, da ingantacciyar hanyar tsaro ta gano abubuwan hawa da suka yi yawa. Daga cikin nau'ikan firikwensin daban-daban, na'urori masu auna firikwensin quartz sun dace musamman don Ma'aunin Ma'aunin-In-Motion (HSWIM) saboda tsayin daka, tsayin daka, da iya jure yanayin yanayi mai tsauri. Na'urori masu auna firikwensin ma'adini, irin su CET8312-A, suna ba da daidaiton aiki ko da a cikin manyan sauri, yana mai da su manufa don aikace-aikacen da ke buƙatar daidaitattun ma'aunin nauyi amintacce a cikin yanayin zirga-zirga mai sauri.

Mai zuwa yana gabatar da mahimman hanyoyin gwaji guda biyu da za a gudanar kafin shigar da Sensor Quartz: Gwajin Insulation da Gwajin Waveform.

1. Hanyar Gwajin Insulation

1) Saka firikwensin Q9 kai cikin soket megohmmeter

2) Saita megohmmeter zuwa matsayi 1000V (an hana amfani da matsayi na 2500V)

3) Juya kuma danna maɓallin gwadawa a gefen agogo, jin sautin "beep", haske mai nuna alama ja a hannun dama yana haskakawa don fara gwaji, lokacin gwaji bai kamata ya zama ƙasa da daƙiƙa 5 ba.

1) Sakamakon gwaji kamar yadda aka nuna:

Nuna sakamakon OL naúrar (GΩ): Mafi kyawun aiki

Sakamakon nuni 163 naúrar (MΩ): Ba za a iya amfani da shi ba

MUHIMMAN NOTE!!! Bayan gwada na'urori masu auna firikwensin da megohmmeter, na'urori masu auna firikwensin suna tara yawan makamashin lantarki. Dole ne a yi gajeriyar kewayawa na'urori masu auna firikwensin don sakin kuzarin da aka adana. Haɗawa zuwa siyan bayanai ko kayan aunawa ba tare da fitarwa ba bayan gwajin rufewa zai lalata kayan aiki tare da babban ƙarfin lantarki, yana mai da shi mara amfani.

1.Waveform Test Method

1) Saka firikwensin Q9 a cikin oscilloscope "CH1" soket, daidaita lokaci zuwa 200ms da ƙarfin lantarki zuwa 500mv, ko daidaitawa bisa ga yanayin rukunin yanar gizon.

2) bugun firikwensin a kowane wuri tare da guduma na roba, oscilloscope yakamata ya nuna fitowar sigina na sigina.
