摘要
桥梁振动信号检测具有十分重要的研究意义,针对当前桥梁振动信号检测误差大等难题,为了提高桥梁振动信号检测正确率,提出了光电测量技术的桥梁振动信号检测方法。首先分析当前国内外桥梁振动信号检测的研究进展,找到引起桥梁振动信号检测效果差的原因,然后采用光电测量技术采集桥梁振动信号,并采用傅里叶变换对振动信号进行变换,去除桥梁振动信号中的噪声,然后提取去噪后的桥梁振动信号检测特征,并采用数据挖掘技术对特征和桥梁振动信号类型之间的关系进行拟合,建立桥梁振动信号检测模型,最后与其它方法进行了桥梁振动信号检测仿真实验,结果表明,本文方法的桥梁振动信号检测正确率高,桥梁振动信号检测误差明显小于其它桥梁振动信号检测方法,同时加快了桥梁振动信号检测的速度,具有更高的实际应用价值。
The bridge vibration signal detection is of great research significance.In order to improve the accuracy of bridge vibration signal detection,a bridge vibration signal detection method based on photoelectric measurement technology is proposed.First of all,the research progress of bridge vibration signal detection at home and abroad is analyzed,and the causes of poor detection effect of bridge vibration signal are found.Then,the photoelectric measurement technology is used to collect bridge vibration signal,and the Fourier transform is used to transform the vibration signal to remove the noise in bridge vibration signal.And then,the detection features are extracted from the denoised bridge vibration signal.According to the mining technology,the relationship between the characteristics and the bridge vibration signal type is fitted,and the bridge vibration signal detection model is established.At last,other methods are used to carry out the bridge vibration signal detection simulation experiment.The results show that the bridge vibration signal detection accuracy of this method is high,the error is obviously smaller than other methods,and at the same time,the speed of bridge vibration signal detection has been accelerated and has higher practical value.
