The Design And Implementation Of An Intelligent Management System For Public Security Criminal Case Information

Under the background of rapid development of information technology,criminal investigation comprehensive information is an important factor in the detection,prevention and control of public security criminal cases,and the degree of informationization and criminal cases of related links such as collection,integration and extraction can be timely and accurate.The detection has a direct relationship.The traditional criminal case information management system has a relatively narrow channel for information collection,low extraction efficiency a nd single integration means,which has a serious impact on the detection efficiency of criminal investigation cases.This topic is based on the above difficulties,rationalized use of information fusion,intelligent retrieval and other technologies,to bui ld a criminal case information management system based on the local area network,to design an information system to meet the development of the public security criminal case detection line in the new era.The main research contents of this subject include the research work on information construction and standard attributes in the criminal case information management system,which lays a solid foundation for the standardization and standardization of criminal case information collection.Study the types an d workflows of information collected in the current public security criminal case information management system,and build a relatively standardized data processing process to ensure data integrity and legitimacy.Through the in-depth mining of data and the relevant requirements of public security criminal investigation work,a model for intelligently processing criminal investigation comprehensive information data is constructed.The system will design a criminal case information management system architecture based on the internal LAN based on the current work flow of the public security system and hardware and software facilities.This paper takes the development of public security criminal case information management system as the background.In the process of system requirements analysis,the software engineering development method is used as the theoretical guidance,combined with the current public security criminal case information management needs,using UML modeling technology and flow chart analysi s to carry out the process.Based on detailed analysis and modeling,a comprehensive analysis of system functional requirements and non-functional requirements was completed.In the system design process,starting from the background of the construction of the current three-and four-line network of the Public Security Bureau,the network security and the relatively strong processing capacity,the GIAP platform is used as the development tool of the system to complete the system design and finally follow the system.Different sub-modules are developed and analyzed,and the work is prospected and summarized under the premise of current work.
