摘　　要：论文介绍了一种数据交换技术在船舶电站监控系统中的应用方案,能够实现电站监控数据的实时同步交换。阐述了船舶电站监控系统的通信网络架构、数据交换流程和实时通信设计,对实时数据同步交换的实现过程进行了重点说明。该监控系统通过分层分布式通信网络连接多个嵌入式功能模块,由各模块共同协作完成监控功能。为实现监控数据的实时同步交换,嵌入式模块之间采用双口RAM作为共享的数据缓存区,并采用了同步读写触发机制和统一的通信协议。同时还具有很好的兼容性和扩展性。This paper introduces an application scheme of the data exchange technology in monitoring system of ship power station, which can realize the function of real-time synchronous exchange of the power station monitoring data. Integrated Supervisory Control Plat form of ship power station, which is based on synchronous exchange of real-time data. The structure of communication network and the process of data exchange and the design of real-time communication are presented, emphasis on the realization process of synchronous ex- change of real-time data technology. Many embedded modules are connected though the distributed communication network in the monitoring system. The function of monitoring is implemented by cooperation of multi embedded modules. To implement real time synchronous exchange of monitoring data, dual port RAMs are used as shared data buffer among the embedded modules and synchronous R/W trigger mechanism and unified communication protocol are used. In addition, the monitoring system possesses good compatibility and expansibility.
