摘要
本文给出了钢丝绳断丝信号分析中小波基的选取条件，阐述了B－小波的特点及线性B－小波在钢丝绳断丝信号分析中应用的理论依据。实验结果表明，应用B－小波分析成功地区分了内外部断丝，同时也提高了数字信号处理的信噪比和实时性及定量识别的准确性和鲁棒性。
The paper gives the selection conditions of wavelet base in broken wires signal processing. Feature of B -Wavelet and theoretic foundation of broken wires signal processing based on B - Wavelet are set forth. Then internal and external broken wires are successfully separated by identification with B - wavelet. It improves accuracy and robustness of quantum identification. It still improves signal-noise ratio and real-time nature of data signal processing.
