Research On Fire Monitoring System Of High-rise Building

With the acceleration of urbanization,people’s requirements for the quality of the living environment continue to improve,the development of high-rise buildings with each passing day,but in its rapid development at the same time,a series of high-rise building safety problems with fire safety as the main body also appear.In view of the current high-rise buildings,most of the use of single temperature measurement,no fire linkage fire monitoring system,there are problems such as high false alarm rate,existing fire equipment can not be effective rescue.Therefore,based on Zig Bee technology,this paper studies the fire monitoring and fire extinguishing technology of high-rise buildings.The research content of this paper includes:(1)A technical scheme of fire monitoring system for high-rise buildings is proposed.Aiming at the special application scenarios of high-rise buildings,a Zig Bee-based fire monitoring system for high-rise buildings is proposed,and a design scheme combining "indoor and outdoor" dual modules,"monitoring and fire fighting" is constructed,which improves the problems such as high false alarm rate of traditional fire monitoring system and ineffective rescue of existing fire fighting equipment.(2)Indoor monitoring module design based on Zig Bee.The multi-sensor fusion numerical probability algorithm is proposed to make up for the shortage of a single sensor,expand the time and space observation range,and develop the monitoring system interface.(3)Outdoor infrared detection module design.Combined with the robotic arm system,the infrared fire source detection law and the common infrared temperature measurement algorithm are analyzed,and an improved bilinear interpolation algorithm based on local weighted regression is proposed,combined with the environmental temperature compensation algorithm,to realize the infrared temperature acquisition optimization of fire.(4)Kinematics and workspace analysis of the outdoor manipulator module.MATLAB is used to model the manipulator mechanism,and the kinematics is simulated and analyzed,the motion trajectory is reasonably planned and the working space is solved.(5)The structure of mechanical arm and the design of protective cover.Combined with the working conditions,CATIA was used to complete the physical modeling of the manipulator.Comprehensive cost and material characteristics,study all kinds of fireproof materials,determine ceramic fiber and polyimide mixed braided composite material as protective cover material,and design the shape of protective cover.(6)System test.The performance test of the fire monitoring system designed in this paper shows that the parameters and performance of the monitoring system meet the expectations and meet the design requirements of the system.This paper studied the Zig Bee-based fire monitoring system for high-rise buildings,completed the design of the hardware and software system,and set up experiments to verify the feasibility and effectiveness of the proposed method.On the basis of meeting the requirements of high-rise building fire monitoring,it achieved high efficiency and low cost,providing practical reference and theoretical support for the development of high-rise building fire protection.This paper has 68 figures,3 tables and 87 references.
