摘　　要：光纤振动传感具有抗电磁干扰、耐腐蚀、体积小、检测范围大等的特点,特别适合应用于周界防入侵系统中.本文基于ARM 和FPGA,建立了一套分布式光纤传感系统中的数据采集和处理终端,完成硬件系统的设计及软件架构的编写.本采集处理系统以高性能FPGA 为采集系统的主控制器,实现了连续波和脉冲波高低速双通道采集;以ARM9 处理器S3C2440 为主控制器,完成数据的分析及存储、报警功能.在ARM9 上移植的Linux 操作系统的驱动层中完成对FPGA 的配置及数据读取,在应用层完成对数据的处理和检测、存储.本设计方法相比于以往的以PC 机＋PCI 采集卡的方案,具有扩展性强、低功耗、可便携等优势,有着广阔的应用前景.The main work of this paper is to develop a data acquisition and processing unit of distributed optical fiber vibration sensingsystem based on ARM and FPGA. The data acquisition system uses FPGA as its main controller to achieve the dual-channelacquisition of pulse wave and continuous wave. The ARM9 microprocessor S3C2440 is used as the main processor in this systemfor data acquiring/processing/storage. Linux OS is ported to the ARM core and Linux device drivers are developed for configuringthe FPGA sub system and transmitting data. Compared to optical fiber vibration data acquisition methods （PC＋PCI card） before,this method has the advantage of low-power, good expansibility and portability, which makes it a broader usage.
