    • Methods and systems for discriminating among sparking modes are disclosed. In one embodiment, a method includes receiving light from a spark into a spectrometer, generating a light intensity spectrum using the spectrometer, and classifying the sparking mode based on an analysis of the light intensity spectrum. The light intensity spectrum may be analyzed for the presence of an atomic emission and a broad blackbody emission. In further embodiments, light emitted by the spark may be received into a photodetector, and the classification of the sparking mode may be based on an analysis of an intensity profile, including at least one of a rise-time phase, a peak intensity, and a drop-off phase.
    • 公开了用于区分火花模式的方法和系统。 在一个实施例中,一种方法包括将来自火花的光接收到光谱仪中,使用光谱仪产生光强度光谱,并且基于光强度光谱的分析对火花模式进行分类。 可以分析光强度谱的原子发射和宽黑体发射的存在。 在另外的实施例中,由火花发射的光可以被接收到光电检测器中,并且火花模式的分类可以基于对强度分布的分析,包括上升时间相位,峰值强度和 一个下降阶段。
