基于Web服务的E-Police系统架构

传统电子警察系统由于过分依赖单一服务器,在系统运算、网络传输以及存储容量上难以满足海量数据的需求.将Web Service技术应用到电子警察系统,设计了各前端节点对等的集群式服务器加单一后端客户处理机模式的E-Police电子警察系统架构,提出了计算服务、存储服务和查询服务;松散耦合的E-Police系统以3种服务的实现为核心,系统依靠大量前端节点承担主要工作,提高了资源利用率;通过Web服务的准备、发布和建立3步流程,实现了一套完整的任务、资源和数据流管理方案,解决了传统系统计算性能、存储容量与图像质量三者难以平衡的问题. 

Electronic-police system architecture based on Web Service

The traditional electronic-police system cannot adapt well to the requirements of enormous data in terms of compute speed,network-transport speed and storage capacity due to its excessive dependence on single server.Based on Web Service technology,the E-Police system architecture contained cluster-servers of peer-to-peer industrial computers and single back-end client.The compute service,storage service and query service were introduced.The implement of three services was the core of incompact E-Police system,which carried out the work by cluster-servers to increase the resource utilization.A integrated management scheme of assignment,resource and data flow was implemented depending on the preparation,release and establishment of Web Service,which resolved the imbalance among system compute performance,storage capacity and quality of the image.
