Wisdom Fire Protection Technology And Application Based On Wireless Sensor Network

Fire is one of the most common disaster in major disasters.Once a fire breaks out,it usually cause property damage under normal circumstances and result a large number of casualties in severe cases.So the research of the fire detection technology becomes one of the important topics on preventing and strangling the occurrence and development of fire.At present,the design of the many existing fire detection systems' structure is relatively simple,thus it leads to the transmission of fire information is not timely or the occurrence of error alarm and missed alarm,and this brings great difficulties to the fire rescue work.Therefore,this paper studies and builds a set of intelligent fire alarm system based on wireless sensor network,which is cost-effective and can warn in time.First of all,according to the characteristics of the application scene about fire alarm,we carry out a full range of needs analysis and feasibility analysis of the system combined with the wireless sensor network technology and data fusion technology.Then we build the overall architecture of the system and introduce the hardware and software implementation of each function module carefully.Therefore,the acquisition,transmission and integration of the fire information data are achieved.Secondly,through considering the non-structural characteristics of the fire process,we make improvements for multi-sensor data fusion technology and propose an intelligent fire detection algorithm based on wireless sensor network.It's increasing a pre-processing module based on one of the artificial intelligence algorithm to achieve the multi-level hierarchical fusion of the original fire data.Simulation results show that the algorithm effectively improves the efficiency of the system monitoring and has obvious advantages.Finally,combining the analysis of system requirements,we complete the building of the prototype system's platform and test the function and related performance of the system.The test shows that the intelligent fire alarm system designed in this paper can detect the occurrence of fire and warn in time.It meet the design requirements both in the speed and accuracy of recognition.The test shows that the system can achieve the acquisition,processing and analysis of the signal in the fire-rescuing scene,and it also reflects the broad application prospect of the intelligent fire alarm system further.
