The Research And Implementation Of Network Virtual Laboratory Platform

With the fast development of the computer technology and the network technology, the virtual laboratory takes the impetus education pattern evolution one effective method, it gradually becomes in the last few years the domestic and foreign experimental teaching and the long-distance teaching research hot spot. The virtual laboratory platform is the virtual laboratory support platform, it can collect the virtual experiment, the virtual laboratory management, the experimental teaching, the on-line cooperation, the teaching organization management , may reduce on the virtual laboratory difficulty and the work , reduces the development cycle, realizes in wide range large-scale resources sharing.The paper mainly targets at in the virtual laboratory platform the laboratory report and laboratory Assessment the research. The former laboratory report system all is in inlays in the virtual experiment, it lacks the versatility, the laboratory report management function is weaker. Therefore, the paper proposes the research and development general laboratory report production system,which is all virtual experimental the public module, assists the virtual experiment to complete the laboratory report the production, and comments to the laboratory report management (including teacher Comment and information inquiry). In the research process, carries on the analysis to the laboratory report form and the content and the processing flow, base on "general" design thought, propose the general laboratory report template method and take the standard data connection as the foundation data acquisition method. finally separately introduced two methods designs and the realization.Analyzing the flow and the experiment assessment method when the research virtual experiment. Among the traditional experiment assessment the teacher can carry on the monitoring to the process. But at present, majority virtual experiment assessment is for result assessment. User's experimental process is similar to the black box,does not have the feedback and the monitoring. The paper proposes through to laboratory the process modelling, thus carries on the monitoring and the assessment mentality to the process. Introduced to laboratory the process modelling with the aid of the petri net model the method, to laboratory the process track and the control carries on the design, and uses based on the Socket technology real-time data Communication,unified data exchange standard. At the same time, the paper also introduces the partition scoring and the minute value accumulation and so on the many kinds of assessment appraisal method, to evaluates based on the experimental process result with evaluates based on the experimental result has separately carried on the design and the description.
