Fault diagnosis system design of image motion compensation circuit for aerial camera

Abstract

In order to solve fault diagnosis problems about process cumbersome, time-consuming, low operation efficiency due to its own characteristics of the image motion compensation circuit, the fault diagnosis system of image motion compensation circuit based on improved ant colony algorithm (ACO) and virtual instrument technology is designed. Aiming at established model after the detailed theoretical analysis, the real-time and automatic chip level testing to image motion compensation circuit can be realized, which not relying on any standard equipment and additional measuring points. All results of theoretical analysis and actual test to the designed fault diagnosis system shows that the fault coverage, average reliability and location rate to fault devices can reach 100%, 97.73% and 98% respectively. The characteristics of fast speed, high efficiency and high reliability in fault diagnosis show that the researched method can also be used for fault diagnosis of the other electronic equipment system.
