摘　　要：以往为大型警务数据处理系统设计的数据分流平台处于持续开发阶段,其分流速率、分流准确度和分流效果均不佳。因此,设计新型大型警务数据处理系统数据分流平台,其核心设备是ULV处理器。大型警务处理系统拥有三个层次的数据流,平台的ULV处理器使用物理层硬件对三个层次的数据流进行硬件分流,并利用已写入哈希映射函数分流方案的网络服务处理器,对硬件分流结果进行软件分流,给出第一、二层次数据流的分流结果。第三层次数据流经由协议分流进行硬、软件分流结果的细化和修正,以获取其最终分流结果。经实验结果分析可知,所设计的平台具有较高的分流速率和分流准确度,分流效果好。As the previous data distribution platform for large-scale police data processing system is still at the development stage, and its data distribution efficiency, accuracy and effect are poor, a new data distribution platform for large-scale police data processing system was designed, whose core equipment is the ULV processor. The police data processing system has three levels of data streams. The ULV processor of the platform uses the physical hardware to distribute the data streams in three lev- els. The Web services processor written in Hash mapping function distribution scheme is adopted to distribute the result of the distribution hardware by software. The distribution re suhs of the data streams in the first and second levels are given. The data stream in the third level is refined and corrected according to the protocol to acquire final distribution results. The analysis of the experiment result shows that the designed platform has high efficiency, high accuracy and good effect of distribution.
