Research And Implementation Of Digital Virtual Workplace System Based On Cloud Computing

This paper designs and implements a digital virtual workplace system based on cloud computing.The system is dedicated to changing the traditional service mode through emerging information technology,building a workplace with strong interactive digital service construction capability,and provides a unified service display and delivery platform.Service demanders can obtain all kinds of services they need at any time and anywhere through a unified service display platform.At the same time,personalized recommendation of services can be realized through the service recommendation mechanism.In the process of constructing digital virtual workplace system,the main research work of this subject has the following points: 1)Design and implement a DSDFS distributed file system,realize high availability of files through copying,realize fast storage and access of large files by file segmentation,and realize the infinite expansion of cluster storage capacity by means of node expansion.It provides a solution for the digital virtual workplace system of large file storage.2)A 3D model retrieval method based on shape distribution and curvature is proposed,which combines global and local features of the model to construct more descriptive feature descriptors.It provides a fast and accurate method for the selection of resources when building system services.3)An improved personalized recommendation algorithm is proposed.By introducing the weight of time and the weight of popular items in the calculation of user similarity,and finally calculating the similarity between K-means clustering algorithm and object,the final recommendation set is obtained.To improve the personalized recommendation service function in the service display platform.This topic uses 3D modeling technology,virtual reality technology and component technology to realize the rapid construction of digital virtual service,and has strong human-computer interaction function.At the same time,it uses cloud service theory and technology to construct an open,collaborative and shared cloud service environment,which integrates various digital virtual services into a unified access platform through the cloud service model.Application and testing finally show that the cloud computing-based digital virtual workplace system researched in this paper can build immersive and interactive digital virtual service for service providers without software knowledge,change the traditional service mode and enhance thedigital service.Interactivity,while sharing service resources and data,and promoting the development of digital services.
