摘要：针对船舶传统通信系统存在的问题，提出了基于控制器局域网络（CAN）总线的通信系统网络化方案，分析了磁罗经数据采集模块、无线数据CAN总线接入模块、PCICAN总线接口卡模块、步进式方位仪舷角测量模块的设计理念，给出了最基本的CAN总线接口电路原理图，采用了TTCAN协议和双冗余设计理念，最后设计了防雷抗干扰和脉冲群测试实验以测试数据通信系统的可靠性。研究结果表明,系统的可靠性在很大程度上得到了提高，该设计在船用高精度数字磁罗经的项目中得到了成功的应用。

Abstract: Aiming at the shortages existing in the traditional communication system of the marine ship, a network method based on controller area network(CAN) bus was presented. And the design ideas of the magnetic compass data acquisition module，wireless data CAN bus access module, PCICANbus interface card module, stepbystep direction side angle measurement instrument module were given. Then the most basic CAN bus interface circuit schematic was given, and the TTCAN agreement, dual redundant design concept were introduced. Finally, lightningproof and antijamming test, pulse group test were used to test systems reliability. The results indicate that the reliability of the system has been enhanced. This design has been successfully applied in the marine highprecision digital magnetic compass.
