Ukuhlolwa Kwenzwa Ye-Quartz ngaphambi kokufakwa ku-Weigh-In-Motion

I-Weigh-In-Motion (WIM) ubuchwepheshe obukala isisindo sezimoto ngesikhathi zihamba, okuqeda isidingo sokuma kwezimoto. Isebenzisa izinzwa ezifakwe ngaphansi kwendawo yomgwaqo ukuze ithole izinguquko zengcindezi njengoba izimoto zidlula kuzo, ihlinzeka ngedatha yesikhathi sangempela ngesisindo, i-ekseli yomthwalo, nesivinini. Amasistimu e-WIM asetshenziswa kakhulu ekuphathweni kwethrafikhi, ekuphoqeleleni ukugcwala ngokweqile, kanye nokuhlelwa kwezinto ukuze kuthuthukiswe ukusebenza kahle nokuphepha.

I-WIM inikeza izinzuzo ezibalulekile, ezihlanganisa ukuphazamiseka kwethrafikhi okuncishisiwe, ukuqapha kwesikhathi sangempela, nokuphepha emgwaqeni okuthuthukisiwe ngokuthola izimoto ezigcwele kakhulu. Phakathi kwezinhlobo ezihlukahlukene zezinzwa, izinzwa ze-quartz zifaneleka kakhulu i-High-Speed ​​Weigh-In-Motion (HSWIM) ngenxa yokunemba kwazo okuphezulu, ukuqina, kanye nekhono lokumelana nezimo zemvelo ezinzima. Izinzwa ze-quartz, njenge-CET8312-A, zinikeza ukusebenza okungaguquki ngisho nangesivinini esiphezulu, okuzenza zilungele izinhlelo zokusebenza ezidinga ukukala isisindo esinembile nesithembekile kuzimo zethrafikhi ezihamba ngokushesha.

Okulandelayo kwethula izindlela ezimbili ezibalulekile zokuhlola okufanele zenziwe ngaphambi kokufaka inzwa ye-Quartz: Ukuhlolwa Kokushunqisiswa Nokuhlola I-Waveform.

1. Indlela Yokuhlola I-Insulation

1) Faka ikhanda lenzwa ye-Q9 esokhethi ye-megohmmeter

2) Setha i-megohmmeter ibe yi-1000V isikhundla (akuvunyelwe ukusebenzisa isikhundla esingu-2500V)

3) Vula bese ucindezela inkinobho yokuhlola ngokwewashi, uzwe umsindo othi "beep", isibani esibomvu kwesokudla sikhanyisa ukuze uqale ukuhlola, isikhathi sokuhlola akufanele sibe ngaphansi kwamasekhondi angu-5.

1) Imiphumela yokuhlolwa njengoba kukhonjisiwe:

Isibonisi seyunithi ye-OL (GΩ): Ukusebenza okuphezulu

Umphumela wokubonisa iyunithi engu-163 (MΩ): Ayikwazi ukusetshenziswa

IQINISO ELIBALULEKILE!!! Ngemva kokuhlola izinzwa nge-megohmmeter, izinzwa ziqongelela amanani amakhulu kagesi. Izinzwa kufanele zifinyezwe ukuze zikhiphe amandla agciniwe. Ukuxhuma ekutholweni kwedatha noma okokusebenza kokukala ngaphandle kokuyikhipha ngemva kokuhlolwa kwe-insulation kuzolimaza okokusebenza okunamandla kagesi aphezulu, kuyenze ingakwazi ukusetshenziswa.

1.Indlela Yokuhlola I-Waveform

1) Faka ikhanda lenzwa ye-Q9 ku-oscilloscope "CH1" isokhethi, lungisa isikhathi sibe ngu-200ms kanye ne-voltage ibe ngu-500mv, noma ulungise ngokuvumelana nezimo zesayithi.

2) Inzwa yokushaya nganoma yisiphi isikhathi ngesando serabha, i-oscilloscope kufanele ibonise ukuphuma kwesignali ye-waveform

Akukho okukhiphayo kwesignali njengoba kukhonjisiwe ngenhla

Okukhipha isignali njengoba kuboniswe ngenhla

I-waveform enhle

I-waveform engalungile

1.Ukuhlola Ikhwalithi Yezinzwa

Amazinga Okuhlola Okuvikela:

• Iyunithi ye-OL GΩ: Ukusebenza okuphezulu
• Kukhulu kuno-10 GΩ: Isimo esihle
• Ngaphansi kuka-1 GΩ: Iyasebenziseka
• 300MΩ nangaphansi: Ayinasici (Isicucu)
