摘要
为了满足船舶上越来越多的电子控制单元对信息共享的需求,采用基于CAN总线的网络结构,利用SAE J1939的通信报文格式,并且结合船舶上实际的动力设备运行情况,制定出可应用于船舶动力设备上的部分通信协议,以飞思卡尔MC9S12单片机为核心设计了系统的软硬件,通过搭建仿真实验平台,实现所设计系统能满足设计功能。基于SAE J1939在船舶动力应用中的软硬件设计方法,其他工作技术人员也可以利用此方法设计制定船舶上其他一些设备的通信协议。
In order to investigate the information sharing requirement of increasing electronic control units. The network structure of CAN and the message format of SAE J1939 are adopted, combining with actiial utility equipment running status on the ship to develop a part of communication protocols for ship applications. The hardware and software of the system mainly based on Freescale MC9S12 single-chip microcomputers are designed. Following, the simulation experiment platform is conducted to achieve the designed system and satisfy the design requirement. Based on SAE J1939 application in Marine power of hardware and software design , the other technical staffs can also use this method to design communication protocols for other equipments on ships.
