Home Security Based On Wireless Transmission System Design

With the development of science and technology and the progress of society,people’s requirements for the quality of home life have gradually improved.Driven by the rapid development of the Internet of Things and embedded technology,many large enterprises such as Samsung,Haier,xiaomi and so on have stepped into the research and development field of smart home products,and the modern home model has formed a global change.Under the background of the increasing exposure of many safety hazards in the traditional living environment,in order to meet the intelligent,convenient and efficient security needs of modern families,smart home security systems were born.However,in real life,most of the intelligent security systems have problems such as high development costs,inconvenient operation,and poor user experience,which cannot meet the security needs of modern families in the actual situation.Therefore,this thesis designs and develops a home intelligent security system based on embedded technology,which realizes an intelligent security system that combines practicality,reliability and personalization.Combined with the development background and significance of smart home security systems,this thesis designs and develops smart home security systems based on embedded technology on the basis of research results at home and abroad.The system starts from the perspective of low cost and low power consumption for the design of software and hardware modules,and collects temperature and humidity,combustible gas types and concentrations,and camera video signals in an all-round way.The user can switch and control the electrical equipment through the client,and realize real-time video monitoring of the household gas and environment.The design mainly includes four modules: client,server,induction and wireless sensing network.Qt technology is used for client interface design.The server uses the Exynos4412 chip developed by South Korea’s Samsung as the core processor,and uses Linux as an embedded operating system to port the server.The sensing end uses an stm32 microprocessor to collect information through temperature and humidity sensors,MQ-2 smoke sensors,etc.The wireless communication module uses Zigbee wireless sensing network technology to achieve data transmission.Finally,through the above design,the project independently built a test platform for the intelligent security system,and the operation effects of the system basically completed the design expectations.Through the test on the performance and safety of the home intelligent security system,the test results show that the system operation interface is simple and efficient,the user can remotely monitor and manage the home environment according to the camera,sensor and home appliance control function,and the user can take precautions according to the early warning of the fire on the server side.In general,the system operates stably in various tests,basically meets the expected requirements of low development and maintenance costs,convenient operation and reliable operation,and has certain use value in the home intelligent security system industry.
