在本文中，我们提出了一种新的方法来检测和监测挥发性有机化合物（VOC）气体泄漏，通过使用热释电（或被动）红外（PIR）传感器，其光谱范围与VOC气体的吸收带相交。从PIR传感器获得连续时间模拟信号。该信号被离散化并在真实的时间中被分析。在小波域中提取特征参数，并使用基于马尔可夫模型（MM）的分类器进行分类。给出了实验结果。
In this paper, we propose a novel method for detecting and monitoring Volatile Organic Compounds (VOC) gas leaks by using a Pyro-electric (or Passive) Infrared (PIR) sensor whose spectral range intersects with the absorption bands of VOC gases. A continuous time analog signal is obtained from the PIR sensor. This signal is discretized and analyzed in real time. Feature parameters are extracted in wavelet domain and classified using a Markov Model (MM) based classifier. Experimental results are presented.
