摘要: 为了实现将CAN总线网络应用于鱼雷制导系统中，通过对基于CAN总线网络的鱼雷制导系统信息传输的试验验证与硬件设计，形成了在进行鱼雷制导系统CAN总线结构网络设计时，应该从制导系统CAN总线协议规划及报文制定、供电体制规划、CAN总线终端阻抗匹配及输入输出隔离设计以及电磁环境要求等方面来提高CAN总线数据传输可靠性的经验和设计方法。初步试验表明，CAN总线网络技术可以满足鱼雷电子系统的通信需求。Abstract: To apply CAN-bus network to torpedo control and homing systems, we verified the data transmission of torpedo control and homing systems based on CAN-bus network via test, and designed the corresponding hardware. Attentions were paid to improve reliability of data transmission of CAN-bus network in such design sections as determining CAN-bus protocol and CAN message, planning power supply, matching CAN-bus terminal impedance, setting input-output isolation, and satisfying requirement of electromagnetic environment, etc. Experimental result shows that the CAN-bus network can meet the communication requirement of torpedo electronic system.
