文章介绍了一种基于位总线的舰载武器系统试验数据采集系统的设计。系统由主采集器和五个采集节点组成 ,主采集器完成对系统的控制、串行数字量采集、节点采集数据的汇总、数据实时处理和存贮、采集节点完成模拟信号的采集。主采集器与采集节点间采用位总线通信 ,用双绞线连接 This paper introduces a design of the test data acquisition system of shipborne weapon system based on bit bus. The system consists of a main collector and five acquisition nodes. The main collector completes the control of the system, serial digital acquisition, summary of data collected by the nodes, real-time data processing and storage, and collection of nodes to collect analog signals. The main collector and acquisition nodes using bit bus communication, with twisted pair connection
