一种变压器运输过程机械冲击损坏的频域分析方法

本发明涉及数据处理技术领域，尤其涉及一种变压器运输过程机械冲击损坏的频域分析方法，首先物资运输在线监测终端通过加速度传感器实时采集变压器运输过程中的振动加速度信号，然后基于数据缓冲区中的加速度数据，采用快速傅里叶变换计算加速度幅值；接着根据加速度幅值计算冲击能量；然后取各个频率下的冲击能量最大值，与变压器损害冲击阀值进行比较；大于变压器损害冲击阀值则判定有损害发生，生成预警报文。本发明为变压器运输行业提供一种频域分析方法，可以更准确的分析变压器的机械冲击损害程度，从而有效避免漏检和误判。 The invention relates to the technical field of data processing, in particular to a frequency domain analysis method for mechanical shock damage in a transformer transportation process, which comprises the following steps of: firstly, acquiring a vibration acceleration signal in the transformer transportation process in real time by a material transportation online monitoring terminal through an acceleration sensor; calculating an acceleration amplitude by adopting fast Fourier transform; impact energy is calculated according to the acceleration amplitude; then, comparing the maximum impact energy value under each frequency with a transformer damage impact threshold value; if the transformer damage impact threshold value is greater than the transformer damage impact
