摘要
某新型大型船舶采用以太网进行各个设备之间的信息交互,且联网设备的网络特性相对复杂。因此针对大型船舶的联网设备的网络特性,提出一种用于研发联网设备网络协议和检测网络运行状态的模拟器设计方案。该方案采用PC104作为硬件架构,在Linux平台上使用面向对象技术对各联网设备的网络特性进行建模,实现对各联网设备网络特性的模拟;并采用编写脚本文件的方法增强了模拟器的仿真灵活性和软件扩展能力。该模拟器构建的网络实验平台,能够加快联网设备和网络协议的研发速度、检测网络性能和降低开发费用。
A new type of large vessel takes advantage of Ethernet to communicate with other equipments and the network properties of the equipments are relatively complex. Based on the characteristic of networking equipments in large vessel, a scheme for net protocol research and network performance detection is introduced. In this system, PC104 is adopted as hardware framework. And the modeling of the network equipments＇ characteristic is accomplished on Linux with the thought of object-oriented programming. Moreover, the adoption of script file enhances the flexibility and expandability of the simulator. And the net experimental platform, which is constructed by simulator, is testified to be efficient to shorten the research time of net protocol and equipment, detects the net performance and reduces research costs.
