Abstract: | 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. |
