Abstract

The distributed measurement and control system require technology to solve complex synchronization problem among distributed devices. It can be solved by using IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems to synchronize real-time clocks incorporated within each component of the system. In this paper, we implemented the IEEE 1588v2 PTP emulator on BlueScope BL6000A using a delay request-response mechanism to measure clock synchronization.

분산 환경의 계측 및 제어 시스템에서 분산된 디바이스들의 복잡한 동기화 구조를 해결하기 위한 기술의 필요성이 요구되며 그러한 분산시스템 환경에서 시간 동기화를 위해 IEEE 표준인 정밀 클럭 동기화 프로토콜(Precision Clock Synchronization Protocol)을 사용함으로써 문제를 해결 할 수 있다. 본 논문에서는 정확한 시간 동기화를 계측하기 위해 지연 요청-응답(Delay Request-Response) 메커니즘을 이용하여 IEEE 1588v2 PTP를 계측하고 제어 할 수 있는 기능을 BlueScope BL6000A에 구현하였다.
