Design And Implementation Of Smart Home Gateway Based On MIPS Architecture

In recent years,with the Internet of Things technology,Internet technology,the rapid progress of embedded technology,and chip and related devices more and more integrated,performance and functionality more powerful,coupled with Internet and large data platform technology Rapid development,for the embedded network provides a perfect support.All kinds of communication technology with embedded technology will make intelligent home-related equipment disruptive development,contributed to the intelligent home equipment Internet,full of wisdom.If you want to choose an application to the embedded,Internet of things and Internet technology fully integrated together,then the smart home application is a good choice.This paper first introduces the history of the development of intelligent home gateway and the development at home and abroad,and then discusses the overall design of smart home systems.In this paper,a detailed combing the gateway-related needs,in view of the current needs of the relevant intelligent home,focused on the gateway used in a number of hardware technology.These hardware technologies mainly include AR9331 processor module circuit,Ethernet communication module circuit,touch screen circuit,audio output circuit,AC-DC circuit,DC-DC circuit,ZigBee communication circuit meter,RS485 communication circuit,sensor circuit and so on.Later introduced the gateway software design,mainly Openwrt open source operating system transplantation,Sedona middleware porting,field communication bus software protocol design.Finally,the function and performance of the gateway are debugged and tested.The so-called debugging main debugging gateway hardware circuit,ensure its function easy to use,performance to achieve good results.The test is to test the gateway hardware circuit performance and indicators to see if it can meet the needs of smart home environment.The intelligent home gateway designed in this thesis is very rich in function,and can meet the needs of most users for intelligent home.Hardware,the gateway to consider the construction workers to facilitate the installation of lead,the use of electricity supply.Gateway with ZigBee wireless and RS485 field bus communication capabilities,the hardware can be as much as possible to compatible third-party smart home equipment to facilitate the expansion of the latter part of the device.Gateway with a liquid crystal touch screen,the user can easily control the localization,real-time effective.Gateway also comes with WiFi and Ethernet Internet access,intelligent home gateway in the data and Ethernet server communication,remote control.The gateway integrates a number of sensors,so that the gateway can monitor its surrounding environment index.These hardware features combined with advanced Openwrt operating system and modular Sedona development framework,the smart home gateway scalability,flexibility,ease of use has been greatly improved.System integrators use this gateway to quickly meet user needs and extend third-party devices.Users can use this gateway to achieve local and remote intelligent home control.
