Design And Implementation Of Smart-home Control System Based On Linux System

With the continuous progress of science and technology,the continuous improvement of people's living standard.People are beginning to pursue a higher quality of life,while smart home-related products have also got rapid development.In order to quickly occupy the market,major and smart home-related high-tech companies continue to increase R & D investment.A set of safe,intelligent,convenient,efficient,high-quality smart home system is their primary goal that they pursue.Continuous development of artificial intelligence,networking,cloud technology,embedded,wireless sensor networks and other technologies and smart home market huge demand.Especially in the country,in the field of intelligent home research and design,it has got an unprecedented development.However,the inconsistent communication protocol standards and software compatibility issues limit the development of smart home.This design takes into account the system cost,power consumption,performance,scalability,reliability,etc.,but also taking into account the user's excellent experience.The system uses the embedded system,single chip,ZigBee wireless network transmission,sensor,graphical interface Qt and other technologies.A set of intelligent home control system solutions completed on the basis of previous studies.At the same time,the design of the relevant hardware circuit modules,hardware drivers,and graphical interface of the Qt application,and Linux system transplant,verify the feasibility of this program.From the functional composition,the system consists of four parts,which are the main controller,intelligent gateway,sensor nodes,ZigBee wireless sensor network.By reading a large number of intelligent home-related literature,completed a lightweight intelligent home solutions.The system uses the S5PV210 host controller,2.6.35 version of the Linux kernel,Qt graphical interface application.The ZigBee wireless sensor network technology is used in the network.The CC2530 chip produced by TI is used as the sensor node(including the ZigBee coordinator and the ZigBee terminal node),and uses a simple star network topology and ZigBee protocol stack.Finally,the function and performance of the whole intelligent home control system were tested.The results showed that the system was stable and completed all the functional requirements of the intelligent home control system.The system is excellent to reflect its low cost,low power consumption,practicality,convenience,scalability,high reliability and so on.
