为满足船舶综合信息平台对全船各子系统或设备网络互联的需求，针对某型船网络结构，基于W7100A网络微处理器+CAN控制器SJA1000，设计船舶网络综合网关，给出具体的软硬件设计方法。移植μC/OS-II嵌入式操作系统，使数据传输具有很高的实时性，实现船舶以太网、CAN和RS485三种网络的互联及数据的共享，该网关全部采用双冗余的网络结构，具备很高的可靠性。
In this paper, a marine network protocol converter based on W7100A is designed to meet the demand of the Integrated Platform Management System for each subsystem or device internetworking. Ethernet, CAN and RS485 protocol conversion is realized. The hardware design and software program design of related interfaces are described. The μC/OS-II embedded operating system is successfully transplanted and this can achieve the high real-time transmission of field data. The design achieves interconnection of the three networks and data sharing. The protocol converter uses dual-redundant network structure with very high reliability.
