中文摘要: 随着数控技术的进步, 数控系统由单机系统向分布式系统发展, 机床存储介质的容量不能满足复杂数控程序存储的需求. 在分布式数控系统中应用NFS可以解决存储空间限制的问题, 而且便于用户管理共享文件. 介绍了NFS技术, 并结合实际需求将NFS服务由传统的使用IP分配资源改进为依据用户信息分配资源.

中文关键词: 网络文件系统 NFS 分布式数控系统资源分配

Abstract:With the progress of CNC(Computer Numerical Control) technology, CNC system has developed from a stand-alone system to a distributed system. The capacity of the machine storage can't meet the needs of complex numerical control program. Applying NFS(Network File System) service to the distributed CNC system can solve the problem of limited storage space, and is convenient for users to manage the shared files. This paper introduces the key technology of NFS and changes the resource allocation strategy from using IP address to using user information.

keywords: network file system NFS distributed CNC system resource allocation
