摘要
以嵌入式处理器ARM7为核心,结合CAN总线通信技术,设计了一套电弧光保护及监控系统。系统实时检测电弧光,可在弧光发生时以最快速度切断电路,并将弧光信息通过CAN总线传送给上位计算机。给出了系统的硬件组成与程序流程。实验表明,本系统比传统保护系统响应快、可靠性高,而且通信距离远,可在极大程度上降低弧光发生带来的灾难性后果。
This paper introduces a fault arc protecting and monitoring system based on ARM7 and the CAN bus. The system can cut the circuit quickly as fault arc occurs. In addition, the system can send the arc information to PC via CAN bus. The hardware of the system and the flow chart of program are also provided.
