摘　　要：针对分布式水下爆炸瞬态信号的获取设计了采集与存储系统。整个分布式系统以无线传感器网络为基础,测试节点与主控站之间的数据采用无线方式传输。使用基于SPI总线协议的无线模块,主控站通过发送命令控制节点的数据存储与存储测试,同时各个传感器节点加入时间同步技术,使得各测试节点互不相关且具有记忆重发的功能。In this paper,distributed underwater explosion transient signal acquisition and storage system is designed to capture the signals in the entire distributed system based on wireless sensor networks,data are transmitted between nodes and the master station by wireless network,wireless modules are based on the SPI bus protocol,the master station control nodes by sending commands to store and test the data and each sensor node is subject to the time synchronization,so that each node is independent of each other,and has a memory for data retransmission.

关 键 词：瞬态信号 分布式系统 串行外设接口 时间同步
