A Smart Home Control System Design And Implementation Based On ZigBee And OpenWrt

With the rapid development of Internet technology, Internet technology has been more comprehensive application.Belongs to apart of the Internet of things smart home industry is with the continuous improvement of people’s living standard and rushed to heat up, according to the related media to interview and survey,"Internet+" topic smart home has been in the top three.Smart Home (Smart Home), also known as Home Automation, Home Automation), is based on residential and integrate building Automation, network communication, information appliances, equipment, structure, system, management, service as one of the efficient, safe, comfortable, convenient, environmental protection and energy saving living environment;Use of network communication technology, integrated wiring technology, security technology, audio and video technology, automatic control technology, will and household life of the various subsystems organically combined together the wisdom of highly intelligent family. Smart home is still in its infancy in our country, belongs to the rising sun industry, potentially huge consumer groups, especially the youth group with purchasing power.In this paper, through investigation and research about the present situation of smart home at home and abroad, analyzes some problems of the smart home system appears stage.Part of the in order to solve these problems, by looking at data and related technical specification, the design of smart home system based on ZigBee and OpenWrt.This paper according to the functions of smart home products in the market now, and the user’s requirements, after clear principles of good design, determines the network communication protocol of the whole system needs to adopt the technology, and then according to the selection of communication protocol to determine the development platform and external application circuit is designed.Consider to reduce the cost of system solutions, not the traditional way of ZigBee smart home unique gateway solution, selected the OpenWrt as gateway system, on the basis of the compilation and transplantation of OpenWrt and without loss of routing functions as a way to ZigBee gateway, the last WEB interaction design the user interface and APP software easy to use.
