摘要
在对通用加速度传感器与低频加速度传感器在低频响应上的性能进行频谱检测与对比分析的基础上,对拉索基频检测的基频法和倒谱法进行组合的混合基频拾取技术进行了优化,提出了适用于斜拉桥索力基频分析的新型混合算法;该算法在保证基频分析进度不变的前提下,有效地提高了基频识别的速度和抗干扰能力,而且在嵌入式系统中进行开发实现更为有效和容易,具有较强的工程实用价值。
The paper carries out a comparing analysis about general acceleration sensor and low acceleration transducer at low--frequency response performance. At the same time, an optimization of the mixed fundamental frequency technology is given. And this paper presents a new composite algorithm which is suitable in the fundamental frequency analysis of the tension of cable. Under the same progress of analyzing fundamental frequency, this method is not only improving the speed of the base frequency identification but also making Embedded System Development more effective and easier. This algorithm has a practical engineering value.
