Quartz Sensor Test isati yaiswa mu Weigh-In-Motion

Weigh-In-Motion (WIM) inyanzvi inoyera huremu hwemotokari padzinenge dzichifamba, zvichibvisa kukosha kwekuti mota dzimire. Inoshandisa masensa akaiswa pasi pemugwagwa kuti aone kudzvanywa kwekuchinja sezvo mota dzichipfuura pamusoro padzo, ichipa chaiyo-nguva data pahuremu, axle mutoro, uye kumhanya. Masisitimu eWIM anoshandiswa zvakanyanya mukutonga kwetraffic, kuwandisa kwekuita, uye zvigadziriso zvekuvandudza mashandiro nekuchengetedza.

WIM inopa mabhenefiti akakosha, anosanganisira kuderedzwa kwekuvhiringidzwa kwemotokari, kutarisa-nguva chaiyo, uye nekuvandudza kuchengetedzwa kwemigwagwa nekuona mota dzakawandisa. Pakati pemhando dzakasiyana-siyana dze sensor, ma sensor e quartz anonyanya kukodzera High-Speed ​​Weigh-In-Motion (HSWIM) nekuda kwepamusoro-soro, kusimba, uye kukwanisa kutsungirira mamiriro ekunze akaoma. Quartz sensors, senge CET8312-A, inopa kuita kwakafanana kunyangwe pakumhanya kwakanyanya, ichiita kuti ive yakanakira maapplication anoda chaiwo uye akavimbika huremu kuyerwa mune inokurumidza-inofamba traffic traffic.

Izvi zvinotevera zvinosuma nzira mbiri dzakakosha dzekuedza dzinofanirwa kuitwa usati waisa iyo Quartz Sensor: Insulation Test uye Waveform Test.

1. Insulation Test Method

1) Isa sensor Q9 musoro mune megohmmeter socket

2) Seta megohmmeter kune 1000V chinzvimbo (inorambidzwa kushandisa 2500V chinzvimbo)

3) Tendeuka uye wodzvanya bvunzo switch wachi, inzwa "beep" ruzha, dzvuku chiratidzo chemwenje kumusoro kurudyi chinovhenekera kuti utange bvunzo, nguva yekuyedza haifanirwe kunge isingasviki 5 masekonzi.

1) Migumisiro yekuedza sezvakaratidzwa:

Ratidza mhedzisiro OL unit (GΩ): Kunyatsoita

Ratidza mhinduro 163 unit (MΩ): Haikwanise kushandiswa

CHINOKOSHA CHINOKOSHA!!! Mushure mekuedza ma sensors ane megohmmeter, ma sensors anounganidza akawanda emagetsi emagetsi. Masensa anofanirwa kunge ari pfupi-yakatenderedzwa kuti isunungure yakachengetwa simba. Kubatanidza kutorwa kwedata kana kuyera michina isina kuburitswa mushure mekuyedzwa kwekudzivirira kunoparadza midziyo ine yakakwira voltage, zvichiita kuti isashande.

1.Waveform Test Method

1) Isa sensor Q9 musoro mune oscilloscope "CH1" socket, gadzirisa nguva kusvika 200ms uye voltage kusvika 500mv, kana gadzirisa zvinoenderana nesaiti mamiriro.

2) Kurova sensor pane chero nguva nesando yerabha, oscilloscope inofanirwa kuratidza chiratidzo che waveform kubuda

Hapana chiratidzo chinobuda sezvaratidzwa pamusoro

Signal kubuda sezvaratidzwa pamusoro

Positive waveform

Negative waveform

1.Sensor Quality Assessment

Insulation Assessment Standards:

• OL unit GΩ: Zvakakwana kuita
• Yakakura kupfuura 10 GΩ: Mamiriro akanaka
• isingasviki 1 GΩ: Inogona kushandiswa
• 300MΩ uye pazasi: Yakashata (Chikafu)
