摘　　要：介绍了基于过程控制领域中应用的一种新技术-OPC技术的发展、技术规范及其在控制系统中的应用.在此基础上,结合先进控制软件技术,提出了基于OPC过程回路的客户端软件包的基本框架和设计思想.该软件包相当于OPC的客户端,其应用程序的开发工具采用Visual Basic 6.0,通过OPC自动化接口,利用OPC协议来读写服务器数据,实现了客户端的数据采集.最后给出了结论,展望了基于OPC的客户软件的开发与应用前景.Based on OPC technology applied to process control field, this paper introduces its development, specification and application in control system. And then, integrated with advanced control software technology, the design idea and basic framework of client software package based on OPC process loops are put forward. The OPC client is exploited under Visual Basic environment that communicates with OPC server through OPC automation interfaces with OPC specification, and client data acquisition is implemented. Finally, the conclusions are drawn and the development and application of client software package based on OPC are forecasted.
