疏浚仿真器的数据管理和数据通信

Data Management and Communication of Dredging Process Training Simulator

介绍了我国首台 1 75 0 m3/h绞吸式挖泥船疏浚作业仿真训练器的数据管理模式和数据通信流程 ,分析了所采用的系统数据集中管理模式的特点 ,说明了利用客户 /服务器模型进行计算机网络数据通信的方法 .其中数据管理用到共享内存技术 ,所有需要使用系统数据的进程均与共享数据库相连 ;数据通信中主模型计算机作为服务器端 ,其他仿真计算机作为客户端 ,运用 TCP/IP协议及 socket套接字 ,各通信程序以后台方式运行 。

This paper briefly introduces the data management mode and communication process of 1750m 3/h dredging processing training simulator which is firstly developed in China. It analyses the centralized management mode's features of the system data, and explains the method of the computer net data communication by using client/server model. The share EMS memory is used in data management. All of the processes that need to use the system data are connected with the share database. In data communication, the main model computer is by way of the server, the other simulation computers are by way of the clients, and TCP/IP and socket are employed. Each communication program runs by means of background to realize the net data communication.
