Using infrared thermography, computer image signal processing and electronic technology, a TIP-I circuit fault detector is developed to detect non-contact faults of the circuit. The detection efficiency is high and the application is simple, which makes up for the shortcomings of the traditional detection methods. The working principle, system composition and basic work process of the detector are introduced. The problem of determining the size of the thermal field of view field is solved and the thermal image is spliced by using the method of “getting in and out”, which takes into account the space of the thermal camera Resolution and field of view size, get satisfactory circuit thermal image, easy to fault diagnosis. The identification test and the actual use of the circuit fault diagnosis rate is high, the detector for the miniaturization, and laid the foundation for practical.
