舰船综合监控中上层计算机网络的冗余设计

通过网络实现舰船综合监视、控制和管理是当前舰船自动化的发展方向。现有的舰船综合监控产品一般由多台地理分散的下位机和一台上位监控管理计算机组成 ,尚未形成网络化的上层监视、控制与管理。为了灵活地实现舰船仪器和设备的综合监控 ,同时解决高可靠性、高实时性和可诊断性等问题 ,针对上述不足 ,结合相关项目的研究与开发 ,在现场网络的基础上设计了上层计算机网络 ,给出了其中的软件分布 ,并对系统中的工控、监控、网络和数据库等方面的冗余设计和实现进行了详细的叙述。

Redundancy Design of the Upper Layer Computer Network in Ship Integrated Monitoring and Control System

It is the world's trend in ship automation development to integrate the monitoring, control and management of the instruments, equipment and system both on the bridge and in an engine room by a network. The products currently used for monitoring and control usually consist of many distributed micro computer units and one management personal computer. The monitoring and control functions are performed not on a computer network but in an independent computer. To overcome the disadvantage and to improve the reliability, real time and diagnosis abilities, we present a feasible design of the computer network for the system based on a field network and give the distribution of software of the system with high performance. The redundancy design of software and its implementation are described in detail.
