Design And Implementation Of Home Security System Based On Sensor Network

With the development of science and technology,high-tech products can be seen everywhere in modern family life.While improving the quality of people’s life,it also increases unsafe factors to a certain extent,such as home appliances spontaneous combustion,gas explosion and information theft.Intelligent home begins to be applied in people’s life,among which the most important subsystem is the family security system,the stable operation of the system can ensure the safety of people’s life and property.Therefore,it is of great significance to build a perfect family security system to improve people’s living standards and ensure safe home life.The main reasons why the home security system in China cannot be realized and popularized mainly lie in the system false alarm,high cost and inconvenient installation.Under the background of rapid development of Internet of Things technology and wireless sensor network,the home security system has a good opportunity for development.First of all,based on the literature summarizes to the domestic research results,and the content of related family security systems were introduced,this system mainly USES the sensor network,the Android programming techniques and technologies such as WIFI technology,second home security system function,put forward on the basis of demand analysis based on sensor networks of family security system overall design,including design system overall architecture,function module design,design requirements and software functions,etc.,for the follow-up system hardware,software design and practical application to provide direction and guidance.Then,the paper designs the hardware part based on the single-chip microcomputer,clarifies the overall design plan of the system hardware,selects the WIFI node design of the CC3200 chip on this basis,and analyzes the selection and design of each module of the system,mainly including video modules,Smoke sensor module,flame sensor module,gas monitoring sensor module and alarm and GSM Modem module.And design the system software part,including Android client and Windows client,design and analyze the WIFI node software design and the upper computer software design in the system software.Finally,the application and performance of the system are analyzed.The home security system has many functions such as image acquisition,video monitoring,datacloud storage,fire prevention,anti-theft,anti-gas leakage,and instant alarm,etc.,and has exerted good results in the test process.Even for the security difficulties in traditional home security systems-fire prevention and anti-theft,high-precision monitoring effects can be achieved through image recognition and other sensor equipment,and the response time of the entire system is relatively short.Through the above test of the server carrying capacity,we can know that the system server can basically carry 10,000 people online at the same time,and the system can meet the basic needs of home security and has good application value.
