Study on Wavelet Filtering Method of Pressure in Concrete Pump Transport Pipe

准确的混凝土泵输送管道压力信号是混凝土泵实时监控和故障诊断的关键。通过小波变换的快速分解和重构算法,对混凝土泵输送管道压力信号进行滤波,有效去除了输送管道压力测量信号中的噪声,取得了良好的滤波效果,为混凝土泵实时监控和故障诊断提供处理和识别依据。

The accurate pressure signal in the concrete pump transport pipe is the key factor of concrete pump on-line controlling and fault diagnosis.Through the fast decomposition and reconstruction algorithm of wavelet transform,the pressure signal in the transport pipe was filtered,the noise in the pressure signal was removed,and good filter result was obtained.It provides the basis of processing and identifying for concrete pump on-line controlling and fault diagnosis.
