Study On Optimum Selection Of Power Supply Scheme For Building Surveillance System

With the promotion of building digital technology,the development of security surveillance system is very rapid.The importance of surveillance system is highlighted in building security,and it has been widely used in various building systems.Because of the continuous working characteristics of the system,the power supply to it has become an important part of the intelligent building.Therefore,from the perspective of construction investors,in order to maximize energy and cost savings,this study establishes an optimum selection model of power supply scheme in building security surveillance system for decision-making reference.Through literature review and analysis,as well as investigation and discussion of the application site,this paper obtains the influencing factors in the optimum selection of power supply scheme for building surveillance system.In this study,through the formulation of rules,DELPHI method is used to select,filter and organize,forming the index system of the optimum selection.In order to construct the optimum selection model,the weight of each evaluation indicator is calculated by AHP.And then combined with the fuzzy evaluation method,the results are ranked to optimize.Additionally,the judgment of the model in practical applications is illustrated to enhance its practicability and feasibility.Finally,two projects with different conditions are evaluated,calculated and analyzed by using the model,and the results are compared and verified with the actual application effect.It proves the validity of the model.
