Abstract

본 발명은 다축포터블스캐너를 이용한 간이자동 초음파탐상장치 구조에 관한 것이다. 종래에는 작업자의 수작업에 의존하고 있어, 신뢰성확보에 대단히 어려움을 겪지만, 본 발명장치는 초음파탐촉자(33)의 위치를 정밀하게 검출할 수 있도록 6개의 상호 다른 독립적 운동방향을 갖도록 6축포터블스캐너(100)을 채택한 초음파탐촉자(33)을 검사할 구조물의 소정의 위치에 놓게 되면, 상기 초음파탐촉자(33)에서 주사된 초음파가 반사되어 나온 신호를 처리함과 아울러 상기 탐상기기의 각축의 회절각을 검지하여 검사위치를 처리하는 각종 위치센서와 인터페이스 그리고 컴퓨터 메인메모리에 탑재된 결함 및 위치신호 분석 소프트웨어는 신호처리장치를 통해 PC의 메인 메모리에 입력된 엔코더 카운터값과 결함 신호의 디지털 데이터를 이용해, 초음파 탐촉자(33)의 위치는 엔코더 카운터의 계수값을 이용하여 포터블스캐너(100)의 정기구학적 계산을 수행하면 결정할 수 있으며, 시험 대상체에 대한 상대적 위치는 좌표변환을 통하여 얻음으로서, 결함의 위치는 앞에서 구한 결함 위치를 초음파 탐촉자의 스캐닝 운동과 연동시켜 3차원 결함 이미지를 구축할 수 있다. 결함의 종류는 초음파 형성 인식 기법과 신경회로망기법을 적절히 활용하면 결정할 수 있다. 이와 같이 본 발명의 시스템을 활용하면 초음파 탐상시험의 신뢰성을 획기적으로 제고하게 되어 이를 바탕으로 대형 구조물의 안전성 해석과 수명평가의 신뢰성을 높일 수 있을 것으로 기대한다.The present invention relates to a simple automatic ultrasonic flaw detector using a multi-axis portable scanner. Conventionally, it depends on the manual operation of the operator, and very difficult to secure the reliability, but the present invention is a six-axis portable scanner to have six different independent movement directions to accurately detect the position of the ultrasonic probe 33 When the ultrasonic probe 33 adopting the 100 is placed at a predetermined position of the structure to be inspected, the ultrasonic wave scanned by the ultrasonic probe 33 processes a signal reflected by the ultrasonic probe 33 and the diffraction angle of each axis of the flaw detector Various position sensors and interfaces for detecting and processing the test position, and the fault and position signal analysis software installed in the main memory of the computer use the encoder counter value and the fault data inputted into the main memory of the PC through the signal processing device. The position of the ultrasonic transducer 33 is a static kinematics of the portable scanner 100 using the count value of the encoder counter. And to determine when to perform the acid, obtaining a relative position of the test object, through the coordinate transformation, by the fault location is obtained in front of the location of the defect in conjunction with the scanning motion of the ultrasonic probe can be constructed three-dimensional image of the defect. The type of defect can be determined by properly using ultrasonic shaping recognition and neural network techniques. As such, utilizing the system of the present invention significantly improves the reliability of the ultrasonic flaw test and is expected to increase the reliability of the safety analysis and the life assessment of large structures based on this.
