某医用大楼消防及弱电系统设计论文

西南科技大学本科生毕业论文I某医用大楼消防及弱电系统设计摘要：“消防”作为一门学科，正伴随着现代科学技术的发展进入到高科技综合学科的行列，“以防为主，防消结合”，是一个工程技术员必须遵循执行的。本工程为绵阳市中医院灾后重建项目急诊综合楼工程，包括急诊，门诊，体检，住院，办公和食堂。该医用大楼为20层，高86.65m，总建筑面积为18569.8m²，属于一类高层建筑物。地下室为两层主要管理及设备用房。由于该医院层数多，高度过高，结构复杂，用电设备多，负荷大，人口比较集中，一旦发生火灾，火灾蔓延快，疏散困难，扑救难度大，所以必须配置一套完善的消防系统。消防系统包括三大主要部分：火灾自动报警系统、灭火自动控制系统、避难诱导系统。弱电系统包括有线电视系统、通信系统、楼宇对讲系统、消防系统。显然，本设计采用控制中心报警系统，控制器采用两线制。同时在考虑接线方式的简单、安全、可靠，选材必须要防火耐燃，具有应急电源，且从电源端至负荷端的消防用电设备的供电系统与非消防设备供电系统截然分开。关键词：消防系统；火灾自动报警系统；弱电系统；供电系统；西南科技大学本科生毕业论文IIDesignofamedicalbuildingfire-fightingandweakelectricitysystemAbstract:fireasasubject,isaccompaniedbythedevelopmentofmodernscienceandtechnologyintohigh-techcomprehensivedisciplineranks,givingprioritytoprevention,combiningpreventionwithelimination,isanengineeringtechnicianmustfollow.Thisprojectisacomprehensivebuildingengineeringemergencyreconstructionprojectsafterdisaster,MianyangHospitalofTraditionalChineseMedicine,includingemergency,outpatient,medical,hospital,officeanddiningroom.Themedicalbuildingis20storieshigh,86.65meter,foratotalconstructionareaof18569.8squaremeter,belongstoaclassofhigh-risebuildings.Thebasementfortheroomwithtwolayersofmanagementandequipment.Becausethehospitalnumber,toohigh,complexstructure,electricalequipments,largeload,populationisrelativelyconcentrated,oncethefire,thefirespreadfast,difficultevacuation,rescuedifficult,youmustconfigureasetofperfectfirecontrolsystem.Fireprotectionsystemconsistsofthreemainparts:automaticalarmsystem,fireautomaticcontrolsystem,fireevacuationguidancesystem.WeakcurrentsystemincludesacableTVsystem,communicationsystem,buildingintercomsystems,firesystems.Obviously,thisdesignusesthecontrolcenteralarmsystem,thecontrollerwithtwowiresystem.Atthesametime,consideringtheconnectionmodeissimple,safe,reliable,selectionmustbeflameresistance,withemergencypower,andpowerfromtheendtotheloadendofthefirepowersupplysystemforelectricequipmentandnonfireequipmentsupplysystemapart.Keywords:firecontrolsystem;automaticfirealarmsystem;electricalsystem;powersupplysystem;西南科技大学本科生毕业论文III目录第1章绪论.................................................................................................................11.1概述................................................................................................................11.2国内外研究现状及存在的问题....................................................................11.3设计依据........................................................................................................21.4设计流程图....................................................................................................3第2章火灾自动报警系统设计.................................................................................42.1火灾自动报警系统的概述............................................................................42.1.1火灾报警系统的发展.........................................................................42.1.2火灾自动报警系统的组成.................................................................42.2建筑物的特点及相关区域的划分................................................................42.2.1建筑物的保护等级及保护范围.......................................................42.2.2建筑耐火等级划分...........................................................................52.2.3报警区域的划分...............................................................................52.2.4探测区域的划分...............................................................................52.3火灾探测器的选择......................................................................................52.3.1火灾探测器的作用...........................................................................52.3.2火灾探测器的分类...........................................................................52.3.3火灾探测器的选用...........................................................................62.4火灾报警控制器..........................................................................................92.5火灾报警系统附件......................................................................................92.5.1编码手动报警按钮.............................................................................92.5.2消火栓报警按钮.................................................................................92.5.3现场模块...........................................................................................102.5.4编码型声光报警盒...........................................................................102.5.5报警门灯和诱导灯...........................................................................102.5.6总线中继器、总线隔离器和总线驱动器.......................................112.5.7区域显示器.......................................................................................112.6本章小结......................................................................................................11西南科技大学本科生毕业论文IV第3章消防联动控制的设计...................................................................................123.1消防联动控制的概述................................................................................123.1.1设备组成...........................................................................................123.1.2联动控制的总体构架..........................
