摘要:
针对不锈钢废料回收中涂层干扰光谱检测的问题,提出了一种基于激光诱导击穿光谱技术的
涂覆层识别与击穿动态检测方法。该方法利用单点连续脉冲激发,通过监测涂层特征元素与基体铁元素的
相对强度变化,构建了基于滑动窗口统计特性的动态检测判据。在此基础上设定了标准差与均值比值小于
0.1和标准差变化率小于0.01的双重稳定性条件,实现了对涂层击穿时刻的自适应锁定。结果表明,含漆
层与含镀层样本分别在第31和第35个脉冲被精准判定击穿,此时相对强度波动指标低至0.062 7和
0.087 3,标准差变化量分别为-0.005 81和0.001 27,均满足稳定性条件。这验证了该方法能有效规避信
号波动干扰,为不锈钢废料的高效光谱采集提供了可靠的技术支撑。
Abstract:
To address the issue of coating interference in spectral detection during stainless steel waste
recycling, this study proposes a coating identification and dynamic detection method based on laser induced
breakdown spectroscopy technology.This method utilizes single point,continuous laser pulses to
construct a dynamic detection criterion,based on the sliding window statistical characteristics by monitoring
the relative intensity changes between coating characteristic elements and matrix iron elements.On
this basis,a dual stability condition was set with a standard deviation to mean ratio of less than 0.1 and a
standard deviation change rate of less than 0.01,achieving adaptive locking of the coating breakdown time.
The results showed that for the samples containing paint and coating,the breakthrough was precisely identified
at the 31st and 35th pulses,respectively.At these points,the relative strength fluctuation indicators
were as low as 0.062 7 and 0.087 3,with the standard deviation changes of -0.005 81 and 0.001 27,respectively,
all satisfying the established stability conditions.This verifies that the method can effectively avoid
signal fluctuation interference,providing reliable technical support for efficient spectral acquisition of
stainless steel waste.
