疏浚仿真器分布式并行智能接口系统

Distributed Intelligent Interface System of Dredging Simulator

介绍了我国首台1 750 m3/h绞吸式挖泥船疏浚作业仿真训练器分布式并行智能I/O接口系统的组成和I/O数据通信原理,分析了这种I/O接口系统的特点,说明了接口驱动器和接口数据库的设计思想和使用方法以及计算机之间的数据管理和数据通信等.为确保计算机之间的实时通信,采取数据集中管理模式对系统大量实时交换数据进行高效管理,多进程、共享内存等计算机应用及仿真技术的综合运用有效提高了系统高效性和实时能力.

The paper introduces the components and I/O data communication principle of the distributed intelligent I/O interface system of 1750 m3/h dredging processing training simulator, which is firstly developed in China. It analyses the features of this system and discusses the programming thinking on interface driver and management database program. In order to insure the real-time com- munication among the computers, dredging process training simulator adopted the integrative data manage mode to handle a mass of the real-time interactive data in the system efficiently. Some com- puter technologies and simulation technologies, such as multi-thread, shared EMS memory and so on, are employed synthetically to improve the efficiency and real-time quality effectively.
