【摘要】 对目前贵重仪器设备共享中存在的问题进行分析,提出并实现了基于Web的贵重仪器设备共享系统。该系统不仅能够实现贵重仪器设备信息的共享,而且能够实现贵重仪器设备的远程操作,支持多用户的协同工作。针对贵重仪器设备地理位置分布和软硬件平台异构问题对共享模式进行研究,提出了混合式共享模式,该模式能够保证系统的鲁棒性、通用性和可扩展性;为了保证数据和系统的安全性,对访问控制技术进行研究,提出采用基于角色的访问控制技术实现“用户-角色-权限”管理模式,该管理模式能够满足不同用户的多样化需求;为保证系统通用性,提出采用桌面共享技术实现仪器设备的远程操作和共享,支持多用户远程协同工作。更多还原

【Abstract】 Web-based valuable apparatus sharing system is presented and implemented to solve the problems of valuable apparatus sha-ring.Through the system,information is shared and apparatus is operated remotely,at the same time,users work cooperatively.In order to resolve the problem of location distribution and platform heterogeneity,composite sharing model is presented,which ensure robustness,generality and extensibility of this system.The role-based access control technology is introduced and the "user-role-privilege" management pattern is realized to satisfy different users’ requirement and system security is ensured.Furthermore,the system adopts screen-sharing technology to operate the valuable apparatus remotely,which ensures the generality of system.更多还原
