Abstract

Safety and security system have been internationally enhanced in a field of shipping logistics. Accordingly, techniques for safety and security have been studied steadily. The need of portable radiation detection device is increasing by the search of the container is enhanced. In this paper, we propose to study on the application of the temperature compensation algorithm to the platform to improve the accuracy and the realization of portable radiation detection device based on Cortex-A9. Analog board deforms signal output from the sensor. And Cortex-A9 platform analyzes the signal received and displays the results. Additionally we use the temperature compensation algorithm and thereby we ca look the same results even if the temperature changes.

국제적으로 해운물류의 안전과 보안이 강화되고 있다. 이에 맞추어 국내에서 해운물류의 안전과 보안을 위한 기술에 대한 연구가 꾸준히 진행되고 있다. 관련한 기술 중에 컨테이너 검색의 강화에 따라 휴대용 방사선 검출장치의 필요성이 증가하고 있다. 본 논문에서는 Cortex-A9을 기반으로 한 휴대용 방사선 검출 장치의 구현에 관한 연구와 온도보상 알고리즘의 적용으로 결과의 정확도를 향상하는 연구를 제안하고자한다. 센서의 신호를 아날로그 보드를 통해서 준석에 용이하도록 변형시키고 Cortex-A9 플랫폼에서는 신호를 받아 분석하고 결과를 출력한다. 추가로 온도보상 알고리즘을 적용하여 온도가 변해도 같은 결과를 나타낼 수 있도록 한다.
