摘要
Abstract
As the neural network of the plane, the working condition of the airborne electrical circuit directly determines the re?liability of the aircraft electrical system platform. By the analysis of actual airborne electrical wiring cabling, the physical and mathe?matical model is built based on thermal state. Based on the infrared thermal imaging, the method to get the information of wiring fault by detecting the distribution of surface temperature is proposed. Combining the concrete analysis of the infrared characteristic of the line and allowance processing, it shows that the maximum temperature and relatively stable temperature difference in the tempera?ture field are accurately to describe the sensitivity to the heat factory. According to the analysis of the model and the experiment, the technology of infrared thermal imaging is effective for qualitative analysis and diagnosis.关键词
