摘要
本文论述了以多重冗余设计的微机局域网络应用于舰船控制系统中的可靠性,介绍了以此为原则设计的CY8800系统。CY8800系统采用改进的星形网络,即双重树形实时网络,该网络具有节点双重冗余设计,分级树形结构和网络服务器分散到各节点等特点,其可靠性和抗干扰性高。本文还简略介绍了CY8800系统中的控制级、操作级和管理级微机的特点和功能。
The paper expounds the reliability of the micro-computer local network multi-redundant design for marine control system and gives an introduction to CY-8800 system which is designed according to the priciple. A modified star network, i.e. daul tree real-time network, is adopted to CY-8800. It has the features of dot daul-redundant design, levelized tree structures and net servicers discarted to dots, ets. Therefore, it has high reliability and strong anti-interference ability. The paper then gives a brief introduction of the characteristics and the function of the microcomputers of control level, operating level and management level, used in CY-8800. Finally, the reliability of CY-8800 system is calculated and analysed and the application of the system on a 5000t special cargo vessel is presented.
