【摘要】 实验是科学研究的重要技术手段,实验教学是工程教育中必不可少的一部分。随着工程教育形式的丰富以及高等院校招生规模的不断扩大,常规的实验教学模式已经不能满足教学需求,对新实验模式的探索日益显得重要,建立网上实验仪器设备共享与协作的平台是一种有益的尝试。目前国内,将教学实验尤其是将真实实验设备作为资源发布到网上,提供跨学科、跨院系所之间共享的研究工作,尚在起步阶段。从国外远程实验平台的实现技术发展来看,实现实验资源共享的关键就要解决分布式异构的实验设备能被整合为系统,与用户进行交互。本文通过研究远程实验平台的最新进展,提出了以面向服务体系结构来构建在线实验平台的方案,为实现分布在Internet/Intranet上实验的访问和集成提供了一种框架模型。在此架构中,本文定义了一组实验服务的通用接口,提出了一种实验服务动态调用的实现方法。在此架构的实验客户代理组件中,提出了一种基于XML直接面向用户描述实验信息及数据,且支持实验服务调用结果缓存的用户交互模式,此外完成了实验信息中心数据库的逻辑设计。应用面向服务在线实验平台的框架,本文以一块电子教学实验板VI 1508的共享为例,描述了一个在线实验平台原型系统的实现。通过这个原型系统,实践了Web服务相关技术在实验平台中的应用,实现了各实验系统及辅助资源在平台中的整合。最后通过对原型系统进行压力测试,获得系统中实验服务的性能数据,证明了该系统实现不仅在功能上是有效的,也具有稳定性和可靠性。更多还原

【Abstract】 Experiment is an important approach of scientific research,and experiment teaching is an essential part of the engineering education. With the diversification of engineering educational styles and the enlargement of the university enrollment,normal experiment teaching methods can not meet the demand of the teaching. Hence it is dramatically important to pursue new teaching models,and it is a good way to build up a platform to share and collaborate experiment resources via Internet. Up to the present, the work at home focusing on releasing the teaching-experiment devices, especially the real-experiment devices to the network as sharing resources for the cross-subject and cross-department research, has just started. Concluded from the development of technologies used by international online experiments, the key for the share of experiment resources is to incorporate distributed heterogonous ones into a platform for the interaction with users.After researching the latest progresses of remote experiment platform, this paper proposes a scheme of online experiment platform based on service oriented architecture which is a framework for accessing and integrating the experiments on Internet or Intranet. A group of general service interfaces was defined in this framework and a method of invoking experiment service dynamically was put forward in this paper. A set of interacting policy using XML, with experiment information and data facing experiment customer directly, is also defined in the component of experiment client broker in the framework. Additionally, a logical design of experiment information center is completed.According to the service oriented online experiment platform,taking the online sharing of electronic experiment board called VI 1508 as an example, a prototype of online experiment system is introduced in this paper. In this prototype, web service technologies are applied in the system, and different kinds of experiment resources and assistant resources are integrated. Finally a pressure test on the system is carried on to get the running performance of experiment service in the system,which is proved to be effective, also of great stability and reliability.更多还原
