Marine environment information monitoring system based on CAN bus

针对目前海洋环境噪声测量中测噪节点连接多类型、多传输协议传感器造成数据传输通道错综复杂的现状,提出了一种多测噪点分别采集数据后通过CAN总线方法进行实时、有序的统一数据传输。每个测噪点通过一片STM32单片机来解析不同协议传感器采集的数据,综合处理后通过搭载CAN总线与信息处理接收单元进行通信,并研制了配套的硬件系统。详细阐述了系统工作基本原理、CAN总线通信协议传输方案及软件设计流程,并给出了典型的实验验证结果。

Aiming at the complex situation of data transmission channel caused by the multi-type and multi-transmission protocol sensor in marine environment noise measurement,a new method of real-time and orderly unified data transmission by CAN bus is proposed.After data collection,each noise point is analyzed by a STM32 MCU,communicate with receiving unit by carrying CAN bus,and the corresponding hardware system is developed.The basic principle of the system,the transmission scheme of CAN bus communication protocol and the software design flow are described in article,and typical test result is given.
