摘要
针对电力系统的实际应用,开发光纤光栅温度解调仪表。以DSP和ARM芯片为核心,利用光纤法布里—珀罗(Fiber Fabry-Perot,FFP)解调方法。其中DSP芯片主要用于波长计算,ARM芯片主要用于数据通信。仪表实现100Hz扫描速率,同时计算出16通道,320个光纤光栅温度传感器的温度值。
This paper presents a multi-channel FBG temperature interrogator for power systems. Utilizing fiber Fabry-Perot（FFP） wavelength interrogating method, developed with core. The DSP chip is used in wavelength calculation, while the ARM chip communication. The interrogator can calculate 320 FBG temperature simultaneously with 100Hz scanning rate. DSP and ARM chips as the is mainly used for the data sensors in 16 channels
