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.
