dc.description.abstract | 應變規廣泛使用在許多精密測量系統,這類應用被部署後不希望更動,所以應變感測器需要有很長的電池壽命。最近,這些感測器可用於監測旋轉設備,例如風車和車輪,提供災難性故障的預警,避免危害公共安全。因為無法使用傳統有線的感測器,無線應變感測器就變成相當的重要。
利用脈衝偏壓的方式在電力資源極少的無線感測器上,達到節省能源、拉長使用時間的效果。此外沒有使用恆定的電流,除了可以減少功率消耗,還可以減少應變計的溫度測量誤差。我們利用此技術實際做出無線感測應變規,並且在此架構中進行驗證,在使用32Hz、40%的工作週期下,量測誤差可視為可忽略,在此條件下有效的延長了約50%的使用時間。此研究應用的領域相當的廣泛,目前已經協助風力發電機組葉片應力變化的量測實驗,未來更可以使用在眾多需要監控應力變化的地方,來協助人民保障生命財產安全。 | zh_TW |
dc.description.abstract | This paper presents a pulsed-biasing strain gauge measurement system for wireless sensing applications. The use of pulsed-biasing on the strain gauge can reduce the power consumption of the sensor, which is crucial for low-power wireless sensors. Moreover, without using a constant bias current, power dissipated on the resistive bridge that includes the strain gauge can be reduced. Such reduction can also reduce measurement errors from an increased strain gauge temperature. A strain gauge wireless sensor was constructed using commercially available components. Measurement results show that the pulsed-biasing technique can be implemented with a duty cycle down to around 40% with negligible measurement error at a data rate of 32 Hz. The power saved is equivalent to an increased operation time of 50%. | en |
