实时Web工业控制系统原型的设计与实现

摘要

Considering the fact that traditional industrial control system generally adopts C/S structure and the Web technology fails to act because of HTTP' s incapability to achieve real-time full-duplex communication,a Web system prototype with B/S structure and based on HTML5' s Web Socket technology was designed to meet real-time requirements of industrial control,meanwhile,on this basis,a solution to upgrading an existing industrial control system to the Web-based system was presented.%传统的工业控制系统多采用C/S架构,Web技术难以发力的主要原因在于HTTP技术无法实现实时全双工通信.基于HTML5中Web Socket技术,设计并实现了基于B/S架构且能够满足工业控制应用实时性要求的Web系统原型,同时在此基础上给出了一种现有工业控制系统Web化升级的解决方案.
