基于异构Web服务的虚拟实验平台

目前大部分虚拟实验平台缺乏对异构组件的支持。为此，提出一种基于异构Web服务的虚拟实验平台，该平台采用Web服务技术，以其语言独立性、平台无关性等特点，将异构组件进行Web服务化封装，解决异构组件的通信问题，提高开发效率，实现组件重用。介绍系统平台的架构模型和系统实现的关键技术，讨论对异构组件进行服务化封装及实验流程执行引擎的设计与实现过程，并以该平台为基础，通过Web服务封装将C++和Matlab开发的图像处理组件集成到系统中，构建数字图像处理虚拟实验室。

Virtual Experimental Platform Based on Heterogeneous Web Service

At present,most of the virtual experimental platform lack support for heterogeneous components.To solve this problem,this paper presents the virtual experimental platform of a new idea.As known,Web service has some advantages such as language independence and platform independence.This platform can use this technology to convert a heterogeneous component to a Web service component.In this way,this platform realizes the communication of heterogeneous components and improves the efficiency of development and achieves the component reuse.It introduces the architecture model of the platform and the key technology of the system realization,and then discusses how to convert a heterogeneous component to a Web service component,and also discusses the design and implementation for the experiment execution engine.It takes this platform as the foundation and uses Web service technology,some C＋＋ and Matlab components are integrated into this platform to achieve a digital image processing virtual lab
