摘　　要：针对船舶声纳信号采集区域广、传输数据量大的问题,设计了一种基于双层CAN总线的声纳数据通信系统。系统以PIC18F4580单片机作为中间控制器,利用自身集成的CAN控制器与各采集单元节点进行通信,通过外部扩展CAN控制器MCP2510与上位机进行通信,以双CAN总线接口实现双层、多区域数据通信。通过实验检测,无数据传送出错和数据丢失现象,性能稳定可靠。In view of the problems existing in boat sonar signal acquisition of regional broad and large volumes of data,we present a data communication system for sonar based on two-double can bus.At the heart of system is a PIC18F4580 MCU controller,it uses its own integrated CAN controller to communication with the acquisition unit node,and uses an external CAN controller MCP2510 to communicate with the computer.CAN bus interface to realized two-double and multi-regional data collection.Experimental results show that no data transmission error or loss,the system performance is stable and reliable.
