摘要
声纳上传的数据需要高速的具有合适采集频率的数据采集系统才能够实现对船舶声纳数据的提取和分析,文章设计了基于CAN总线的声纳数据采集系统,完整的给出了数据采集系统的总体结构和采集节点的硬件构成,在此基础上重点分析了数据采集系统采样频率和CAN总线接口电路的设计,对于船舶声纳数据采集系统的研究具有一定的借鉴意义。
The data that upload by sonar needs suitable data acquisition system, which owns high transmission speed and appropriate acquisition frequency, so that computer could extract and analyze the sonar data. This paper designed sonar data acquisition system that based on CAN bus, and the complete structure and the hardware of acquisition node were both pointed out, and the key technology problems, like data acquisition frequency and CAN bus communication circuit were also discussed. All this work is significative for researching the sonar data acquisition system that used in boat.
