Design of Infrared Image Detection System for Large-scale Analog Circuit Faults Based on Adaptor Matching
Abstract:In order to improve the effect of analog circuit fault detection, accurately locate and determine the circuit fault area, a large-scale analog circuit fault infrared image detection system with adapter matching is designed. The infrared imaging range of large-scale analog circuit is determined through the three-dimensional precision electric platform; The infrared image edge of the circuit is depicted by positioning marks; use the adapter to uniformly match the input and output interface signals of the circuit under test. Through the three-dimensional precision electric platform, positioning mark and adapter, the thermal imager is jointly controlled to scan the circuit to be tested and obtain the infrared image of the circuit; using the image memory card to store the infrared image of the circuit obtained by scanning; Through the infrared image preprocessing module, filter and process the infrared image, the large-scale analog circuit fault diagnosis module uses the mutual information registration method to register the circuit infrared image in the image memory card, preliminarily determines the circuit fault area through the differential detection method, and uses the thermal sequence detection method to accurately detect the circuit fault components. The communication of the whole system is realized by using the Internet. Experiments show that the system can effectively collect and preprocess the infrared image of the circuit and improve the definition of the infrared image. The system can effectively determine the circuit fault area and accurately diagnose the circuit fault components.
