Design And Realization Of The Police Material Evidence Management System

The police material evidence management refers to the public security of evidencemanagement department receive all items involved, identification and preservation, as well ashandle the case involved evidence migrate work along with the case, and also contains repeland destroy some items. With the social economy development, the difficulty of the caseinvestigation is increasing, and the number of involved physical evidence increases itsextraction, preservation, transfer the management of all aspects of the workload into doublesheets. At present, the management level of evidence is very limited, management tools arelagging behind, and some even stay on the pattern of a few years ago, labor and artisanal alsooccupy a major position. The traditional manual registration operation is time-consuming,high error rate, inefficient queries that can not meet the evidence management actual needs ofthe current public security work. With the public security golden shield project graduallyestablish and improve, the degree of information of public security work is rising, andbuilding efficient, practical evidence management information system, is the need ofeffectively improving the evidence management level. The use of information, intelligentmanagement will significantly improve the work efficiency, make the material evidencemanagement process informatization, automation and standardization.This paper makes a detailed analysis of the business needs of the police materialevidence management, describes the actual business process of the police material evidencemanagement, architecture the whole process modeling and design and implement a efficientand practical material evidence management information system, to meet the basic publicsecurity material evidence management department of the actual need of work. The mainwork includes the following aspects. (1)Through the analysis of the material evidence management business process and theactual needs, use the workflow technology for system modeling. The police evidencemanagement mainly includes the extraction and registration of the involved physical evidence,fill in the identification of a power of attorney, carries on the material evidence pointsinspection operation, and then came into the professional inspection process, evidence storagemanagement (borrow, transfer, destruction and so on, there is a fixed program and approvalprocess, in line with the characteristics of workflow technology. This system based onworkflow technology of material evidence management process modeling, make the materialevidence management process curing, through the realization of workflow technology ofmaterial evidence management business monitoring, ensure the safety of material evidenceitself, to strengthen the material evidence management standardization and improve theefficiency of the management of public security departments of material evidence.(2)Through division and refining the needs of the material evidence management, designeach function module of the material evidence management system.The main functionmodules of the system including the material evidence accepted module, material evidencesorting module, professional inspection module and material evidence library tube module.The whole system based on the MVC model struts and hibernate three layer framework, usesOracle database. Through the independent data interface layer, separate the data layer andmodel layer, achieved with the database of independence.(3)Complete the design of the public security material evidence management system, andtest the final design management system. In eclipse programming environment, use objectoriented programming language Java for writing, and use The Hebernate technology andStruts technology to achieve material evidence management system of web page design andfunctional response. This system based on B/S (Browser/Server) mode, and realize the userthrough the Browser in different site visit, and enhance the flexibility of checking data. and atthe same time, in order to facilitate the inventory system management and search, use thetechnology of the bar code.In the modern society, with the rapid development of Internet information technology,the public security material evidence management information system based on the publicsecurity network engineering construction foundation，standardize the public security materialevidence professional inspection business process, avoid the past the loopholes inmanagement, and monitor the material evidence from the beginning to the end, to ensure thatthe work efficiency and safety. The police material evidence management system plays animportant supplementary role to carry out other business informatization of the public securitydepartment.
