基于CAN总线的船舶声呐数据采集系统研究

Research on ship sonar data acquisition system based on CAN data transmission bus

船舶的声呐系统是获取水下信息的重要途径,在海洋资源勘测、军事侦察和目标追踪等领域有广泛的应用,尤其在军事潜艇中,声呐系统可以获取敌军舰艇的准确信息。由于船舶的声呐系统运行时容易受海浪等外界环境的干扰,导致声呐数据采集的精度降低,影响船舶的勘测能力,因此,研究性能良好的船舶声呐数据采集系统具有重要意义。本文基于CAN数据总线技术和自动化控制技术,设计和开发一种新型的船舶声呐数据采集系统,并对该系统的硬件结构和软件程序进行详细介绍。

The ship's sonar system is an important way to acquire information under the water, have been widely used in ocean resources exploration, military reconnaissance and target tracking and other fields, especially in military submarines, sonar system can get accurate information of enemy ships. Due to the interference of waves and other external environment running sonar system of ships, which leads to the decrease of sonar data acquisition accuracy, influence of survey ship capacity, therefore, it is important to study the good performance of the ship sonar data acquisition system. Based on CAN data bus technology and automatic control technology, a new data acquisition system for ship sonar is designed and developed. The hardware structure and software program of this system are introduced in detail.
