Kuyesa kwa Sensor ya Quartz musanayike mu Weigh-In-Motion

Weigh-In-Motion (WIM) ndi teknoloji yomwe imayesa kulemera kwa magalimoto pamene akuyenda, kuthetsa kufunika koyimitsa magalimoto. Imagwiritsa ntchito masensa omwe amaikidwa pansi pa msewu kuti azindikire kusintha kwa kuthamanga pamene magalimoto amadutsa pamwamba pawo, kupereka deta yeniyeni yokhudzana ndi kulemera, kulemera kwa axle, ndi liwiro. Machitidwe a WIM amagwiritsidwa ntchito kwambiri poyang'anira magalimoto, kukakamiza kuchulukirachulukira, komanso kasamalidwe kazinthu kuti apititse patsogolo magwiridwe antchito komanso chitetezo.

WIM imapereka zopindulitsa zazikulu, kuphatikiza kuchepetsedwa kwa kusokoneza magalimoto, kuyang'anira nthawi yeniyeni, komanso kuwongolera chitetezo chamsewu pozindikira magalimoto atadzaza. Pakati pa mitundu yosiyanasiyana ya masensa, masensa a quartz ndi oyenera makamaka kwa High-Speed ​​Weigh-In-Motion (HSWIM) chifukwa cha kulondola kwambiri, kulimba, komanso kutha kupirira zovuta zachilengedwe. Masensa a Quartz, monga CET8312-A, amapereka magwiridwe antchito mosasinthasintha ngakhale pa liwiro lalikulu, kuwapangitsa kukhala abwino kwa mapulogalamu omwe amafunikira miyeso yolondola komanso yodalirika yoyezera kulemera kwamagalimoto othamanga kwambiri.

Zotsatirazi zikuwonetsa njira ziwiri zofunika zoyesera zomwe ziyenera kuchitidwa musanayike Quartz Sensor: Insulation Test ndi Waveform Test.

1. Njira Yoyesera Insulation

1) Ikani sensa Q9 mutu mu megohmmeter socket

2) Khazikitsani megohmmeter kukhala 1000V malo (zoletsedwa kugwiritsa ntchito 2500V malo)

3) Tembenukirani ndikusindikiza sinthani yoyeserera mozungulira, imvani mawu a "beep", kuwala kofiira kumtunda kumanja kumawunikira kuti muyambe kuyesa, nthawi yoyesa siyenera kuchepera masekondi 5.

1) Zotsatira za mayeso monga zikuwonekera:

Onetsani zotsatira za OL unit (GΩ): Kuchita bwino

Onetsani zotsatira za 163 unit (MΩ): Sizingagwiritsidwe ntchito

ZOCHITIKA ZOFUNIKA!!! Pambuyo poyesa masensa ndi megohmmeter, masensa amasonkhanitsa mphamvu zambiri zamagetsi. Zomverera ziyenera kufupikitsidwa kuti zitulutse mphamvu zosungidwa. Kulumikiza ku zida zopezera deta kapena zida zoyezera popanda kutulutsa pambuyo poyezetsa kutchinjiriza kumawononga zida zokhala ndi voteji yayikulu, kupangitsa kuti zisagwiritsidwe ntchito.

1.Waveform Mayeso Njira

1) Ikani kachipangizo Q9 mutu mu oscilloscope "CH1" zitsulo, kusintha nthawi 200ms ndi voteji kuti 500mv, kapena kusintha malinga ndi malo malo

2) Kumenya sensa nthawi iliyonse yokhala ndi nyundo ya rabara, oscilloscope iyenera kuwonetsa kutulutsa kwa mawonekedwe

Palibe chizindikiro chotulutsa monga tawonera pamwambapa

Kutulutsa kwa siginecha monga tawonera pamwambapa

Positive waveform

Negative waveform

1.Sensor Quality Assessment

Miyezo ya Insulation Assessment:

• Gawo la OL GΩ: Kuchita bwino
• Kuposa 10 GΩ: Makhalidwe abwino
• Pansi pa 1 GΩ: Yogwiritsidwa ntchito
• 300MΩ ndi pansipa: Zolakwika (Zopanda)
