基于ActiveX技术的组态软件Web服务功能的设计和实现

随着Internet／Intranet技术的不断发展，要求组态软件能够实现B／S（Browse／Server）体系结构，从而实现工业过程中应用越来越广泛的远程监控功能。从功能的角度分析了组态软件对于Web服务功能的需求，并据此选择了ActiveX控件客户＋Socket通信的实现方案。介绍了Web服务的系统设计，客户端ActiveX控件的开发和Socket通信的具体实现方案。在实现过程中充分考虑了工业过程控制监控系统中对于数据实时性的要求，从许多方面对此做了优化。

Design and Realization of Web Services on Configuration Software with ActiveX Technology

With the development of Internet/Intranet technology,it＇s essential for configuration software to implement B/S structure to realize remote monitoring and control,which is more and more used in industrial processes.The paper analyzes the requirement of web services of configuration software in the way of function,based on which a solution is provided to realize the web services function,that is,ActiveX control client plus communication through socket.After that the system design, the implementation of ActiveX control and the detailed solution of communication through socket are introduced.In the realization period,the requirement for real-time data in industrial supervisor system is fully considered,multiple optimizations are implemented.
