自动化仪表与控制系统摘要本部分首先介绍了自动化仪表与控制系统当前的基本现状，指出信息安全、安全、过程自动化、环境和质量控制、无线与网络通信、企业集成六方面是本领域的主要关注；相对于国内自动化仪表市场销售额的高速增长而言，自动化仪表新产品的推出显得稍慢；困扰发展的主要技术问题有：仪表、系统和通信的信息保密和安全，微程序和软件的可靠性可互操作问题，及智能仪表信息的利用问题。然后本部分介绍了国内外的发展趋势，说明在控制系统在企业信息化及围绕工程项目的全局和全生命周期信息集成方面的进展，功能安全、无线通信和控制网络当前的发展动向，以及在新技术快速发展的条件下国际标准化成为各国和各跨国公司技术竞争的前沿，集中展示了各项对未来会产生重大影响的成熟和不完全成熟的新技术。本部分第三章是有关国内本领域近两年的进展的，分别介绍温度、流量等测量仪表及阀门和执行机构产品的进展。同时介绍了国内系统产品的发展以及在各项重大工程中成功应用的情况。最后本部分就国内自动化仪表与控制系统的未来发展提出了建议。AbstractAtfirst,thecurrentsituationaboutprocessautomationinstrumentsandcontrolsystemsisintroducedinthispart.Andsecurity,safety,processautomation,environmentandqualitycontrol,wirelessandnetworkcommunication,andenterpriseintegrationaresixfocusesindicatedinthisarea.Processautomationinstruments’marketisexpendedquicklyinChina,whilethedevelopmentofnewproductsisalittleslowly,forwhich,securityandsafetyaboutinstruments,systemandcommunication,reliabilityaboutmicroprogramandsoftware,interoperability,andhowtousetheinformationinintelligentinstrumentsarethemaintechnicalreasons.ThenthedevelopmenttrendinChinaandoverseaonenterpriseinformationmodelandintegration,engineeringsystemprojectsglobalscopeandwholelifetimeinformationintegration,functionsafety,wirelesscommunicationandcontrolnetworkareintroduced.Becauseofhigh-techfastdevelopment,internationalstandardizationbecomefrontareaoftechnologicalcompetitionbothfornationsandmultinationalcorporations,Besidestheinfluenceofnewtechniquesforfuture,matureornot,isfullyexpressed.Domesticdevelopmentstateinrecenttwoyeariscontainedinthethirdchapterofthispart.Productssituationontemperature,flowandothermeasurementinstruments,valvesandactuators,controlsystemdevelopmentandsuccessfulappliedinsomeimportantprojectsareintroduced.Atlastseveralsuggestionstofuturedevelopmentofprocessautomationinstrumentsandcontrolsystemsaregiven.目录自动化仪表与控制系统............................................................................................................1一、自动化仪表与控制系统的基本现状.............................................................................1二、自动化仪表与控制系统的发展趋势.............................................................................3（一）自动化仪表与企业的信息化.....................................................................................3（二）自动化仪表工程项目全局信息和全生命周期信息的整合.....................................5（三）功能安全.....................................................................................................................7（四）无线通信...................................................................................................................10（五）控制网络...................................................................................................................12（六）国际标准化..................................................................................................................
