The experimental results show that for the continuous AE signal generated from the water pipe leak the improved ICA method can effectively improved the location precision, i. e. , the location precision is controlled under 3% for different leak positions.
实验表明,对于水管泄漏产生的连续型AE信号,通过改进ICA算法分离后的定位精度显著提高,不同泄漏点的定位精度均在3%以内。
