网络环境下B/S技术架构对实时控制的影响

B/S Technology Structure’s Influence upon Real-time Control under Network Circumstances

实时控制所需的网络环境主要包括网络平台、数据库平台、管理软件平台等。网络平台是为实时控制提供信息传递和信息共享的基石;数据库平台是为实时控制提供存储和管理数据的黄金宝库;管理软件平台是为实时控制提供的应用平台。然而,并非将这些要素任意堆积就能够构建起支持实时控制的网络环境,而必须对网络、数据库、管理软件等平台进行有效集成,即研究IT技术架构和应用数据库模式的协同,才能使网络环境真正服务于实时控制。本文分析客户/服务器(C/S)技术架构的原理及其缺点,分析了浏览器/服务器(B/S)技术架构的工作流程及其优点。

Netwok environment that real-time control needs mainly includes the network platform, the database platform, the management software platform etc. To constuct network environment which can support real-time control requires effective integration of these platforms, namely coordina- tion of IT technology structure and database mode can cause the network environment to serve the real-time control. The thesis analyses the principle and defects of client/server (C/S) technology structure, work flow and merits of browser/server (B/S) technology structure, and support on real- time control.
