Design And Implementation Of Embedded Smart Home System

With the continuous advancement of technology,the Internet of Things technology has developed by leaps and bounds.People’s requirements for the home environment are also getting higher and higher.In this environment,smart home products have emerged.The smart home system connects independent household appliances and security equipment into one whole,which can realize intelligent management and remote monitoring of the home.High-tech companies related to smart homes are also constantly increasing R&D efforts to achieve rapid market occupation.A safe,intelligent,convenient and efficient smart home system is also the primary goal of current research.Based on system cost,power consumption,reliability and actual demand,this paper proposes a set of embedded smart home system solutions.The program mainly includes four modules:client,embedded network server,wireless network transmission,and home appliance simulation.It realizes the remote control of LED lights,fans and buzzers,as well as the collection of temperature,humidity,illumination and camera information.The client interface design adopts Qt technology,and completes the connection with the server through TCP/IP protocol,realizing user registration,login,and monitoring of the home environment.The embedded network server part adopts Samsung’s exynos-4412(ARM Cortex-A9 core)as the core processor,and the open source Linux system as the embedded operating system,which mainly completes the data analysis of the client and home appliance analog end.The wireless network transmission part uses ZigBee technology to realize communication between the server and the home appliance analog end.The analog terminal of the home appliance adopts the LPC11C14(ARM Cortex-M0 core)microprocessor to realize the control and collection of the simulated home appliance and home environment information by the operation of the LED lamp,the fan,the buzzer,the temperature and humidity touch sensor,and the photosensitive sensor.Finally,a systematic test was conducted.The results show that the system is stable and able to achieve the desired goals and achieve all of the expected functional requirements.At the same time,the system also embodies its low cost,low power consumption,practicability,reliability and other characteristics,and has certain market application prospects and use value.
