一种输电铁塔塔材振动位移实时监测方法
摘要：
本发明公开了提供一种输电铁塔塔材振动位移实时监测方法，步骤1，获取铁塔塔材的加速度信号；步骤2，利用傅里叶变换，将加速度时域信号转换为频域信号，对加速度频谱除以ω2，ω为角频率；步骤3，选取高通频道对步骤2得到的频域信号进行截断滤波后转换为位移频谱；步骤4，将所述位移频谱进行傅里叶反变换为位移时域信号，得到铁塔塔材的实时位移。本发明能够实时监测杆塔塔材的振动位移，在输电导线舞动状态下，便于电力工作人员实时监测杆塔位移量大小，依此来对杆塔的安全状态进行判断，一旦杆塔有发生危险的趋势，能够及时采取补救措施。
摘要（英）：

The invention discloses a tower material vibration displacement real time monitoring method for a power transmission iron tower. The tower material vibration displacement real time monitoring method includes the steps: 1) acquiring an acceleration signal of the tower material of an iron tower; 2) utilizing Fourier transform to convert an acceleration time domain signal into a frequency domain signal, and divided an acceleration frequency spectrum by omega 2, wherein omega is an angular frequency; 3) selecting a Qualcomm high channel to perform filtering truncation on the obtained frequency domain signal in the step 2 and then convert the frequency domain signal into displacement frequency spectrum; and 4) performing Fourier inversion on the displacement frequency spectrum to convert the displacement frequency spectrum into a displacement time domain signal so as to obtain the real time displacement of the tower material of the iron tower. The tower material vibration displacement real time monitoring method for a power transmission iron tower can monitor the vibration displacement of the tower material of the tower in real time, thus being convenient for monitoring the magnitude of the displacement of the tower in real time for a power worker when a transmission conductor is galloping so as to determine the safety state of the tower, wherein once the tower has the trend of danger, remedial action can be taken timely.
