摘　　要：为了解决继电保护装置存储空间有限以及多板卡间文件同步的问题,对数据共享技术进行了研究。针对继电保护的实际应用场景,设计了适用于继电保护装置的网络文件系统。该系统基于用户数据报协议(UDP)和传输控制协议(TCP),采用客户端/服务端架构,每个板卡既是客户端又是服务端。客户端是文件操作请求的发起者和结果的接收者,服务端可响应客户端的请求,因此每个板卡只需存储自身必需文件即可,其他数据文件可随时从远方获取。该系统将共享技术应用于继电保护领域,有效节省了保护装置的存储空间,同时解决了装置板卡间的文件同步问题,具有可移植性好、通用性高的特点。该系统已经通过功能、效率和稳定性测试,成功应用于多个型号的继电保护装置,取得了预期的效果。In order to solve the problem of limited storage space of relay protection device and file synchronization between multiple boards and modules,data sharing technology is studied.Aiming at the practical application scenario of relay protection,a network file system suitable for relay protection is designed.The system is based on user datagram protocol(UDP) and transmission control protocol(TCP) communication protocol,and adopts client/server architecture.Each board or module is both client and server.The client is the initiator of file operation request and the recipient of result.The server can respond to the client s request.Therefore,each board or module only needs to store its own necessary files,and other data files can be obtained from a distance at any time.The system applies the sharing technology to the field of relay protection,effectively saves the storage space of the protection device,and solves the problem of file synchronization between boards and modules.It has the characteristics of good portability and high versatility.The system has passed the test of function,efficiency and stability,and has been successfully applied to many types of relay protection devices.The expected results have been achieved.
