摘　　要：为解决分布式数据传输丢包率过高的问题,建立更加稳定的异构信息同步共享环境,设计基于XML的分布式异构数据同步系统。借助数据转化模块,制定必要的XML生成与解析语句,利用异构模式提取模块,将分布式信息转存至数据库主机中,完成同步系统硬件执行环境的搭建。在此基础上,定义异构数据的分布型格式,根据已知的异构参数设定标准,建立同步性查询规则,完成系统软件执行环境的搭建,结合相关硬件设备结构,实现基于XML的分布式异构数据同步系统设计与应用。实验结果显示,与FPGA多通道型系统相比,基于XML语言的处理系统在面对传输分布式数据时,明显具备更低的丢包率水平,符合维护稳定性异构信息同步共享环境的实际应用需求。In order to solve the problem of high packet loss rate in distributed data transmission,a more stable heterogeneous information synchronization sharing environment is established,and a distributed heterogeneous data synchronization system based on XML is designed.With the help of the data conversion module,the necessary XML generation and parsing statements are formulated,and the heterogeneous mode extraction module is used to transfer the distributed information to the database host,completing the construction of the hardware execution environment of the synchronization system.On this basis,the distributed format of heterogeneous data is defined,the synchronization query rules are established according to the known standards of heterogeneous parameters,the software execution environment of the system is built,and the design and application of XML⁃based distributed heterog⁃eneous data synchronization system is realized combining with the structure of related hardware devices.Experimental results show that compared with FPGA multi⁃channel system,XML⁃based processing system has significantly lower packet loss rate when transmitting distributed data,which meets the practical application requirements of maintaining stable and heterogeneous information synchronization and sharing environment.
