Design And Implementation Of A Law Enforcement Supervision System

ABSTRACT:With the development of video surveillance technology, workflow technology, wireless communication technology, computer network technology and geographic information system technology, we can realize the Public Security Bureau law enforcement supervision networkization and digitalization. So far, the Public Security Bureau online law enforcement supervision system has been built and put into use in more than50cities in China.This article base on the city Public Security Bureau law enforcement supervision project’s requirement, analyze the background and the significance of the project, and discuss the project’s current situation and existing problems, ultimately according to the city Public Security Bureau current situation conclude online law enforcement supervision building’s necessity, target and construction ideas.Then based on the city Public Security Bureau online law enforcement supervision routine work’s workflow ideas design the overall system architecture, obtain the subsystem analysis and function decomposition results, and discuss the system the required software and hardware environment for system running.Then according to the principle of system design and system structure, design the online law enforcement supervision system function’s system sequence diagram, system activity diagram and system class diagram, several major parts in the law enforcement supervision system is designed in detail, including inspector case obtention subsystem, police affairs supervision subsystem, integrated information querying subsystem and system management subsystem etc.. Also based on the principle of system realization stipulate the user interface and external interface required of the system, detailedly design the system’s data structure and relevant database architecture, analyze and realize police affairs case tracking, data exchange service and affairs management etc. transactions content, detailedly illustrate the key technology of the system’s data accession.Finally, take the city Public Security Bureau online law enforcement supervision system specific affairs as an example to operate the system and verify. Through the city Public Security Bureau online law enforcement supervision system using practices demonstrate online law enforcement supervision system has strong vitality, by means of informationization realize fine management target, are effectively promoting online law enforcement supervision and management work development towards higher, faster, more precise.
