摘要
由于以太网拥有良好的性价比,易连易扩等优点,以及在办公自动化、信息处理、工业控制领域的成功应用经验,选择以太网作为舰载武器系统互连的介质已成为不争的事实。但是,传统以太网总线式拓扑结构、载波监听和碰撞检测通信机制所带来的时间不确定性问题,如果不采取有效的措施,就会对舰载武器系统的实时性带来不可预测的后果。本文针对舰载武器系统和以太网的技术特点,提出几种解决实时和可靠性的实用技术。
Choosing Ethernet as internet media for shinbone weapon systems is a definite fact, because it is good at function/cost rate, easy connecting and expanding, and a lot of application experience in auto-office, information processes and industry control. But there is a time indefinite problem brought by topologic structure of traditional Ethernet bus, carrier monitoring and the mechanic of communication collision check. If no effective measure is implemented, an unexpected result of time reality in shipboard weapon systems will come out. This paper introduces several methods to resolve this problem in accordance with the technical feature of shipboard weapon systems and the Ethernet.
