Based On The Design And Development Of Smart Home System Hardware Platform For DFRuino

Smart home will be the future development trend of home and the technical basis for intelligent community and smart cities.Smart home puts the advanced network communication technology,computer technology,the sensor electric elements characteristic design and embedded technology together.It sets the video surveillance, environmental monitoring, home control and other functions as a whole to meet the current demand for high quality of life and information life.Based on " Chinese smart home equipment industry development environment and analysis of market demand forecast forward " analysis, facing the huge domestic market demand, forecasting an average annual growth rate of the industry up to19.8%, the output value of smart home will reach124billion yuan in2015.Smart Home in China has just begun to enter the high-speed development period,there will be a huge potential consumer market.This paper knows about the research of smart home systems at domestic and abroad and analyzes the current smart home system problems.The past realization of smart home ansmission technique is single, the technology is difficult,and it does not favor the user involvement. In order to solve the above problem, this article plans to use the Web long-distance observation and control system and the Open Wrt gateway system and lives at home the system using the DFRuino hardware platform realization intelligence.This article includes the following four parts:The first part has carried on principle of design clearly and analyses user needs, has carried on the multiplex design of the overall system transmission technology.Using combination of wired and wireless networks overcomes the last application for cable transmission in intelligent home design barriers.At the same time, this transmission mode has increased the signal cover scope,it can be better applied in the original home furnishing structure.The second part carries on the design and the development to the DFRuino hardware platform periphery electric circuit equipment, and debugs showing off to be supposed the software realization design function.From the user’s point of view which is designed touch switch with feedback function,the function can not overcome the traditional home switch control platform using the direct control of the problem, while addressing the past smart home system confined to switch control, but it could not monitor the switching state of the problem. This feature can also be used in smart socket function module.The third part of the OpenWrt a secondary gateway system developed on the basis of the original code has been modified according to the needs of smart home system, and prepares the remote Web server configuration and control system in the home gateway,thereby being easy for users in different networks environment, use and maintenance.This compares with the previous smart home system,separating the control platform and gateway system and placing separately the user-friendly devices and the gateway are convenient.The fourth part carries on the design to the long-distance Web observation and control system.Regarding the problem of gateway memory space is small, under the premise without affecting the system function,it uses the static language to carry on the compilation.And aimed at the question of DFRuino UNO R3to control the platform are not able simultaneously to carry on net mouth receiving and dispatching,and the cross territory visits problem realise carry on the design structure change and the procedure.
