摘要
无线光纤光栅振动传感器在未来桥梁及大型基础设施健康监测中有着广泛的应用前景,如何降低能耗是亟待解决的问题。采用曲线拟合技术,可以提取振动波形的特征参数,从而有效降低数据在无线传输中的能耗。通过模拟仿真实验,上述方法可以很好地实现数据压缩,并保证数据传输的准确性。
Wireless Fiber Brag Grating Vibration Sensor will play an important role in the deployment of next-generation, health-monitoring systems for bridges and civil infrastructures. The key problem is how to save energy on wireless data transmition. By using the technology of curve simulating, eigan parameter can be extracted in order to .save the energy exhausted in data transmition. Simulating experiment results show that the proposed technology realizes data compression and preserves the presicion of data.
