Abstract

This paper describes the design of the circuit card assembly to eliminate the communication error on a servo control unit installed in the automated resupply vehicle K56. K56 is a weapon system that automates the supply and loading of ammunition on the K-55A1 self-propelled artillery. As the core item responsible for ammunition movement control, the servo control unit is required to have good communication stability and reliability, but the conventional unit has recognized a problem that communication error intermittently occurs, resulting in an emergency stop phenomenon. We analyzed the communication signal of the servo control unit and identified the failure cause of the circuit card assembly to solve this problem. In addition, the signal interference in data/address line of the circuit card assembly was confirmed through analysis of the failure cause, and redesigned to avoid the interference, such as adjustment of the distance between communication lines and position change. Finally, the proposed cause analysis and redesign were verified through the component of servo control unit and attachment test on K56. We expected these study results to be used as reference for the design of other similar items.

본 논문은 K56 탄약운반장갑차에 장착되는 서보제어기의 통신오류를 제거하기 위한 회로카드조립체의 설계에 대한 연구이다. K56 탄약운반장갑차는 K-55A1 자주포에 탄약 보급 및 적재를 자동화한 무기체계로써, 탄약운반장갑차의 서보제어기는 탄약이동 제어를 담당하는 핵심적인 기능품이다. 따라서, 서보제어기는 K-55A1 자주포의 운용성을 위해 높은 통신 안정성 및 신뢰성이 요구된다. 그러나, 기존의 서보제어기는 간헐적인 통신오류가 발생하는 문제점이 확인되었으며, 이로 인한 긴급정지 현상이 발생한 바 있다. 본 논문은 이러한 문제를 해결하기 위해 서보제어기의 통신신호 분석 및 서보제어기의 회로카드조립체에 대한 고장원인을 식별하였다. 또한 고장원인 분석을 통해 회로카드조립체의 Data/Address 라인에 의한 신호간섭이 발생하는 현상을 확인하였으며, 각 통신회선 간의 이격거리 조정, 위치변경 등의 신호간섭을 회피하는 재설계를 수행하여 통신오류 현상을 해소하였다. 마지막으로 제안된 원인 분석 및 설계의 유효성을 서보제어기 단품시험과 체계장비 부착시험을 통해 입증하였다. 따라서, 서보제어기의 신뢰성 확보를 통한 방위력 향상과 더불어, 통신의 신뢰성이 필요한 유사품목의 설계에도 참고자료가 될 것으로 기대된다.
