摘要
目前,OPC技术在工厂级的监测与控制系统中获得了广泛的应用,但是在远程监控系统SCADA中的应用则要困难很多。本文结合Internet技术,提出了基于Web服务器的远程监控系统的设计思路和体系架构方法。通过Visual Basic语言编程制作了OPC客户端的COM组件,然后将COM组件嵌入到Web网页中,采用ActiveX、ASP、HTML等相关的Web技术就可以实现数据的Web发布和远程工业实时数据监控,从而实现了管理层通过标准的浏览器就可以达到异地管理工业生产现场的目的。该套监控程序已经成功应用于辽宁省教育厅高等学校科学研究项目《工业现场智能化设备的嵌入式软件构件平台研究》中,并且即将应用于化学、石油、钢铁等工业控制领域。
Now OPC is applied widely in factories,but it is more difficuh to be implemented in SCADA system.In the paper , integrated with Internet technology,the design concept and structure organization methods of remote supervisory system based on Web Server are presented.The COM component of OPC client as Web Server is designed in Visual Basic and embedded in the Web . Adopting the related Web technologies such as ActiveX,ASP,HTML, Web release of data and remote industrial real-time monitoring are achieved,and the object of which supervising layer manages the industrial locale by using standard IE browse is alse achieved .It is successfully applied to the research of embedded software component platform of industrial field instruments and is applying in the control fields of chemistry,oil,steel.
