i危险化学品信息系统设计与实现摘要化学品是人类生产和生活中不可缺少的一部分,但它具有易燃、易爆、有毒、有害等特点,因而,我们称之为危险化学品。扎实做好危险化学品的管理,避免因危险化学品的存储或使用不当而引发危害公共安全的事故、案件,实现危险化学品管理工作由传统模式向基于科技化手段的现代模式转变,建立一个实用性强、技术先进、符合公安机关有关危险化学品管理工作规范的信息系统,是一项非常重要且势在必行的工作。本文通过对国内外危险化学品管理现状分析,根据公安局危险化学品管理工作的要求,从实际情况出发,对危险化学品信息系统进行设计并予以实现。主要工作体现在系统分析、系统设计和系统实现三个部分。在系统分析部分,一是进行了需求分析,要求性能准确及时,具备开放性、可扩展性,易用性和易维护性等特点;二是可行性分析,从管理、技术、经济三方面论证了可行性;三是采用E-R模型表示概念结构,通过对用户需求的综合、归纳与抽象,将在需求分析阶段得到的现实世界对象抽象为概念模型;四是分析系统涉及到的实体及各实体对象之间管理与被管理的逻辑关系以及系统主要处理模式之间的数据流程;五是功能需求分析,明确系统需要建立的登记、管理制度,实现各种监控、服务功能。在系统设计部分,对数据库、输入输出界面进行了详细设计。在系统实现部分,本系统的整体开发采用ASP.NET和MVC技术,实现了数据与视图的分离,后台数据库使用的是SQLServer,并通过公安VPN网络实现公安端和企业端的安全联通。所用的开发工具有VS.Net2013、DreamWeaverCS5、VSS(版本控制)、Firework及PhotoShop;编程语言采用的是C#3.0。系统完成后,经过危险化学品信息监管系统(公安端)、危险化学品信息系统(企业端)的黑盒测试,证明系统在功能性、正确性、可靠性、安全性4个方面符合应用要求。关键词:危险化学品,公安机关,ASP.NET,MVC,信息系统iiDESIGNANDIMPLEMENTATIONOFDANGEROUSCHEMICALINFORMATIONSYSTEMABSTRACTChemicalisanindispensablepartofpeople’sproductionandliving,butithasmanycharacteristicssuchasinflammable,explosive,toxicandharmfulsowecallitadangerouschemical.Itisaveryimportantandnecessaryjobtosolidlymakeamanagementofdangerouschemicals,avoidtheaccidentsandcasesendangeringpublicsecuritycausedbystorageorimproperuseofdangerouschemicals,implementthedangerouschemicalsmanagementshiftingfromtraditionalmodeltomodernmodelbasedonthemeansofscienceandtechnologyandestablishainformationsystemwithstrongpracticability,advancedtechnologyandmeetingthepublicsecurityorgan’sregulationsrelatedtodangerouschemicalsmanagement.Withtheanalysisonthepresentsituationofdangerouschemicalmanagementathomeandabroad,thethesis,startingfromtheactualsituation,designsandimplementstheinformationsystemofdangerouschemicalsaccordingtotherequirementsofdangerouschemicalsmanagementofthepublicsecuritybureau.Theworkembodiesmainlyinthreepartsofanalysis,designandrealizationofsystem.Asforsystemanalysis,thefirstoneisaboutdemandanalysis,requiringtheperformanceaccuratelyandtimelyandhavingthecharacteristicsofopenness,scalability,usabilityandmaintainability;thesecondoneisaboutfeasibilityanalysis,demonstratingthefeasibilityinthreeaspectsofmanagement,technologyandeconomy;thethirdoneis,usingE-Rmodeltoshowtheconceptualstructure,toabstracttherealworldobjectsobtainedinthedemandanalysistoaconceptualmodelthroughsynthesis,inductionandabstractionofuserdemand;thefourthoneistoanalyzetheentityinvolvinginthesystemandthelogicalrelationshipofmanagingandbeingmanagedamongtheentityobjectsandthedataflowamongthemainprocessingmodesinthesystem;thefifthoneisthefunctionalrequirementanalysis,makingregistrationandmanagementsystemneedingtoestablishinthesystemcleartorealizethefunctionsofmonitoringandservices.Asforsystemdesign,ithascarriedonthedetaileddesignofdatabase,inputandoutputinterface.Asforsystemimplementation,theoveralliiidevelopmentofthesystemusesthetechnologyofASP,NETandMVC,realizingtheseparationofthedataandtheviewandthebackgrounddatabaseisSQLServer,realizingthesafeconnectionbetweenpublicsecurityandenterprisebythepublicsecurityVPNnetwork.ThedevelopmenttoolsusedareVS,Net2013,DreamWeaverCS5,VSS(versioncontrol),FireworkandPhotoshop;theprogramminglanguageisC#3.0.Aftercompleted,thesystemisprovedtoconformtotheapplicationrequirementsinfouraspectsoffunctionality,correctness,reliabilityandsecurityaftertheblackboxtestingofthesupervisionsystem(publicsecurity)andinformationsystem(enterprise)ofdangerouschemicals.KeyWords:Hazardouschemicals,thepublicsecurityorgans,ASP.NET,MVC,informationsystem1目录摘要..........................................................................................................................................i第一章绪论.............................................................................................................................11.1项目研究背景和意义.........................................................................................................................11.2国内外发展现状及其趋势.................................................................................................................21.2.1危险化学品管理国外发展现状及趋势...........................................................................................21.2.2危险化学品管理国内发展现状及趋势...........................................................................................31.3论文的主要工作及创新之处.............................................................................................................41.4论文章节安排.....................................................................................................................................6第二章相关技术简介.................................................................................................................72.1ASP.NET概述....................................................................................................................................72.1.1ASP.NET的主要内容......................................................................................................................72.1.2ASP.NET的主要优点..................................................................................................................
