Design And Safety Analysis Of Automatic Fire Alarm System For High Rise Residential Buildings

Since the reform and opening up,China’s national economy and urbanization construction has been greatly developed,more and more tall and complex buildings are emerging.However,contrary to the speed of development is the problem of high-rise building fire prevention and control,not only China,but also the whole world has been troubled by it all the time.Building fires are inherently complex,because of the height,volume,personnel density and other reasons,high-rise buildings are more dangerous than ordinary buildings.Once a fire accident occurs,the consequences will be unimaginable and cause huge losses.But there is a safe and reliable automatic fire alarm system in the building,which can greatly improve people’s ability of fire prevention,and also can bring security for people’s life and property.Therefore,this situation requires people to strengthen fire prevention and control,and also put forward higher requirements for the fire automatic alarm system in high-rise buildings,and the safety of the system needs to be analyzed.This article selects the most common high-rise residential buildings in high-rise buildings for design and analysis.Firstly,the fire risk of high-rise residential buildings is carried out,highlight the importance of automatic alarm system for high-rise residential fire prevention.Then,select the example project to carry on the pertinence and accord with the actual situation of automatic fire alarm system design.At the same time,in the design process,combined with the relevant foreign fire standards and specifications.After the completion of the system framework,the equipment layout and type selection are carried out according to the fire protection plan.Afterwards,the Analytic Hierarchy Process(AHP)and Fuzzy Comprehensive Analysis(FCA)are used to analyze the safety of the automatic fire alarm system of high-rise residential buildings,using AHP to establish the safety index system of automatic fire alarm system for high-rise residential buildings,established three first level indicators,twelve secondary indicators and fifty-two tertiary indicators,and get the weight value of each index through calculation.Finally,the FCA is applied to the safety analysis,on this basis,established the FCA of automatic fire alarm system for high-rise residential buildings,and through the corresponding calculation,the security of the system is in the general level and needs to take some measures to improve.This article through the selection of high-rise residential to design and safety analysis of automatic fire alarm system.It effectively solves the problem that system design and security analysis work separately,avoid the situation that design of alarm system into a template and make the result of security analysis worthless.In the process of getting the results,through the AHP and FCA,it can be known that there are many risks in the system and the parts with high risks,also it can be proceed from the design aspect to carry on the improvement.It is not only convenient,but also safe and scientific.It can reduce the workload and improve efficiency when reanalyzing...
