在探伤中经常遇到以脉冲形式出现的伤信号,伴有大小随机变化的连续噪声,包括某些因为仪器平衡点漂移产生的趋势项.有时噪声绝对值可能相当大,甚至超过伤信号.作者提出一种简便有效的方法,可以将伤信号分离出来,并对此方法作了一定的理论分析
In defect detecting
defect signals appear in the form of impulses
accompanied with continuous random noises
including some trend terms produced due to balance drift. Sometimes
the amplitude of noises may be rather large
even larger than the amplitude of the defect signals.The authors put forward a simple and effective method
which can separate the defect signals from noises
and make a preliminary theoretic analysis. At the end of this article
the method is verified by some examples of defect signals in the detection of wire ropes.
