【Abstract】 Based on the conventional X-Ray lacuna-detection device and image collection analysis technique this paper deals with the X-Ray automatic detection system design by using digital control technology. The mechanical device with 4 free-degree coordinative motion is designed and step-by-step electric motors are controlled by using EPROM of combing software with hardware where by the automatic detection by the computer 2-dimentional image formation with low cost can be realized so as to be able to determine the accurate space locations of defects within the inner metal structure components. The in-situ application indicates that the system designed in this paper is stable and reliable to satisfy the requirements of non-destructive automatic detection of the products.更多还原
