借助红外辐射理论，建立了破损导线的热辐射场和红外传感器对其输入响应的模型。研制和开发了一种新型的导线破损的红外检测与故障诊断仪。提出了基于峰峰值邻域特征参数的综合识别判据在线识别断股故障信号以及用二进小波对突变信号奇异性检测来离线识别断一股信号和股波信号，这种故障识别方法既可以提高故障识别效率又可以保证故障识别的精度。
With the help of infrared radiation theory, a model of the thermal radiation field of damaged conductor and the response of infrared sensor to its input is established. Developed and developed a new type of wire breakage infrared detection and fault diagnosis instrument. A comprehensive identification criterion based on peak-peak neighborhood characteristic parameters is proposed to identify the failure signal on-line and to detect the singularity of the abrupt signal by using the binary wavelet to off-line identify the first-strand signal and the second-strand signal. This fault identification method can either Improve the efficiency of fault identification can ensure the accuracy of fault identification.
