Design And Implementation Of GPS Mobile Law Enforcement System Based On Smart Phone

In the mobile law enforcement system, it's essential to record maritime law enforcement information and terminal location. Develop a scientific, advanced mobile law enforcement system, to facilitate the resolution of existing maritime law enforcement process appears such as difficult to protect the crime scene and get evidence, the information recorded incomplete and not timely reflect. GPS mobile law enforcement system integrating global satellite positioning system, database technology, computer network, communication technology, and based on the concept of"mobile information platform", to design a set of advanced mobile law enforcement management system.First of all, the key technologies used in GPS mobile law enforcement system are introduces. And through analyze the system requirements; design the overall scheme of the system, software architecture and application architecture. Analyze the detailed function of service management system and client system respectively according to the adopted design scheme which is combined of B/S mode and C/S mode.Secondly, discuss difficulties and realization of the key technologies of the system. Use the mobile database to store basic data to ensure the client application still running normally when mobile devices offline. Use the Direct Push Email technology to automatic push information tip in order to ensure mobile device can normally sending and receiving tip while distribute task. Use the WCF distributed communications technology to build system solutions to realize data synchronization between remote database and mobile database. Also use GPS positioning technology to realize the terminal's location at real-time.Finally, complete function testing of the client system and testing of the overall system, test run results are analyzed, and point out the areas for improvement.
