GZX网络软件体系结构设计和实现

Design and realization of GZX network architecture

在GZX网络体系结构中,根据网络安全性要求高和客户机是数据处理主体的应用需求,选用成熟而交互性强的C/S架构。为了实现远程客户计算机在中心计算机的控制下进行远程现场数据处理,在中心计算的应用程序中,设计了多线程的黑板系统消息处理机制,解决了多客户、多消息情况下往往会出现消息阻塞系统无法运行的问题。在客户计算机的应用程序中,采用了消息中断处理机制,根据中心计算机的指令消息,进行现场数据处理,并反馈状态消息和数据处理结果。

Based on TCP/IP and GZX network, a novel method of messages processing is designed and applied. In the GZX network, the client-computers are main bodies of the data processing, and at the same time the security and reliability of the GZX network are very important. So the ripe C/S architecture is selected, and the interactive mode of C/S architecture is very good also. In order to accomplish a great deal of data processing by the client-computer under the control of the center-computer, a multi-thread blackboard approach is designed in the application program of the center-computer. It is an effective solution to the problem that message of multi-client is too much to run the system. The method of message interrupt processing is used in the application program of the client-computer. By receiving the control massage from the center-computer, those remote datum are processed by the client-computer, and the results and the status message are sent back to the center-computer.
