摘要
阐述了船用网关的主要功能:实现上层网(以太网)与下层网(现场总线网)之间的信息交换;实现现场总线网实时报警的中文图形显示;提出船用网关的方案设计方法、硬件组成、软件组成和具体实现;在PC/104上用嵌入式实时操作系统VxWorks实现船用网关的功能并给出了关键代码。
This paper explains the main function of ship-used gateway： information communication between the top net （Ethernet） and the lower net （Fieldbus） ,graphic display in Chinese for Fieldbus realtime alarm. It presents the scheme of project design, specified hardware, software structure and detailed realization of the ship-used gateway. The function of the ship-used gateway is realized on PC/104 by use of the embedded real time operation system VxWorks, and the key codes are provided.
