摘要
介绍了光纤电流传感器的性能特点，详细地论述了光纤电流传感器的噪声根源及如何准确无误地检测出掩埋于噪声中的微弱信号。着重介绍了数字多点平均技术，并给出了基于数字多点平均技术的检测电路和程序流程图。
The characteristics of a fiber optic current sensor (FOCS) are described in this paper. The noise source in FOCS and accurate detection of the weak signal lurking in the noise are discussed in detail. The paper puts emphasis on signal digital multiple - point averaging technique(SDMAT) and the detecting circuit and procedure flow - chart based on SDMAT are given.
