【摘要】：随着我国经济的快速发展，社会结构的不断变化，刑事案件不断增多，积累的案件也越来越多。刑事犯罪分子运用的犯罪手段也越来越先进,反侦察能力越来越强。因此，刑事犯罪侦查工作面临严峻的考验,工作方式和手段需要进行必要的调整。近年来，公安刑事侦查信息网络建设发展迅猛，“金盾工程”的实施，为公安刑事侦查部门使用数字化、网络信息化技术奠定了坚实的基础。在公安系统中，通信技术、网络技术和计算机技术为代表的现代化信息技术被越来越广泛地应用，特别是公安信息网络在刑事案件的计算机网络化管理中发挥了巨大作用，提高了公安刑事侦查部门对刑事犯罪信息的处理能力。为了进一步实现信息资源的共享，加大刑事侦查能力，满足刑事侦查部门业务工作的需要，必须使用更先进的信息技术对刑事犯罪信息进行管理和应用。因此，本文设计并实现了联网刑事案件侦查系统。本文联系实际结合刑事侦查部门的实际工作要求，指出传统C/S两层结构的刑事侦查信息系统存在的弊端，确认SSH三层架构能够有效地解决传统架构存在的一系列问题，其逻辑性及交互性更强，更加安全和方便，因此，确定采用基于新一代SSH三层结构来设计警用联网刑事案件侦查系统。本文在计算机软件工程和设计思路的指导下，重点阐述了刑事案件侦查系统的设计思路和实现方法。设计并实现了联网刑事案件侦查系统的数据库ER图，根据数据库ER图，设计了详细的数据库逻辑结构。在此基础上，完成了对联网刑事案件侦查系统的整体设计。本文从业务模型着手，对联网刑事案件侦查系统的需求进行了分析，使用UML设计了业务流程图、用例图、功能结构图等。刑事侦查处理流程主要包括受案、立案、侦查、破案、结案五个阶段。系统用例主要包括接报案件用例、受害人用例、嫌疑人用例、现场勘查用例、案件处理用例等内容。系统融合了刑事案件的人、案、物、证、线索等相关信息。所包括的八个子模块分别是现场勘察、受理登记、仪器设备、公文收发、物证档案、技术人员、单位记事、辅助信息模块。各个功能模块根据实际刑事侦查工作情况相互关联，构成完整的刑侦系统。本系统在设计过程中充分考虑到公安部门对数据管理的实际需求，采用了由省级刑侦库与地区刑侦库二级联网的方案。系统的实现从登录模块开始，通过系统类图、程序代码、程序运行流程图及其操作界面四个方面进行阐述，分别介绍了现场勘查、受理登记、仪器设备、公文收发、物证档案等模块的实现。同时，本文利用SOM网络的聚类功能提供了一种全新的案件分析方式。SOM网络从案发时间、案发区域、作案手段和工具以及袭击目标上寻找刑事案件的相似点。系统测试结果表明，本系统符合设计要求，用户界面简单友好、操作方便，，能够通过用户界面实现对各项相关业务信息的监视、控制与管理。满足了公安部门刑事侦查业务的实际工作需求。
[Abstract]:With the rapid development of China ' s economy , the changing of social structure , the increasing number of criminal cases and the accumulation of criminal cases , the criminal methods of criminal investigation are becoming more and more advanced and the anti - reconnaissance capability is more and more powerful . In recent years , the development of criminal investigation information network is becoming more and more advanced and the anti - reconnaissance capability is more and more powerful . In recent years , the development of criminal investigation information network has become more and more widely applied , especially the public security information network has played a great role in the computer network management of criminal cases . In order to further realize the sharing of information resources , the criminal investigation ability is increased , and the criminal investigation department has to use the advanced information technology to manage and apply the criminal offence information . Therefore , the paper designs and implements the criminal investigation system of the networked criminal case . This paper points out the shortcomings of the traditional C / S two - layer structure criminal investigation information system , and confirms that the three - layer structure of SSH can effectively solve a series of problems existing in the traditional architecture , which is more secure and convenient . In this paper , a new generation of SSH three - layer structure is used to design the investigation system of the criminal case investigation system . According to the database ER diagram , a detailed database logic structure is designed . On this basis , the whole design of the investigation system of the networked criminal case is completed . This paper analyzes the demand of the investigation system of the networked criminal cases from the business model , and uses UML to design the business flow chart , case diagram , function chart and so on . The realization of the system is described in four aspects : system class diagram , program code , program running flowchart and its operation interface . The system test results show that the system meets the design requirements , the user interface is simple and friendly , the operation is convenient , the monitoring , control and management of the relevant business information can be realized through the user interface , and the actual working demand of the criminal investigation service of the public security department is met .
