摘　　要：根据地震预警技术、FBG应力监测技术和FBG加速度传感器特点,指出光纤传感技术是未来地震预警的应用趋势,分析了FBG加速度传感器的基本结构原理,并对地震相关参数的估计方法作了介绍,提出一种基于FBG的高速铁路轨道监测系统和基于FBG地震加速度传感器的高铁地震预警系统的融合组网方案,实现二网合一,简化布网。According to the earthquake early warning technology, FBG stress monitoring technology and the characteristics of the FBG accelerometer, that the optical fiber sensing technology is the trend of application of earthquake early warning is pointed out. The estimation methods of related earthquake parameters are intro- duced, while the basic structure principle of FBG accelerometer is analyzed. Above all, the networking solu- tion of the high-speed railway track monitoring system based on FBG and earthquake early warning system based on FBG earthquake accelerometer is proposed, which realizes two networks into one and simplifies the networking.
