The Design Based On The Atmega128Smart Home Controller

Along with the rapid spread of the electronic computers and electronic technology rapid development. People started to do not satisfy the traditional family living environment. This paper tries to introduce intelligent household control system.Basically is to satisfy user intelligent household control requirements and design.On analyzed the current smart home controller,the paper designed a solution based on AVR Microcontroller Smart Home Controller._First introduced overall composition of the system, And then discusses the hardware design in detail. This system takes the Atmega128microcontroller as a core,uses the designer of modular and analysis the function of each module and hardware circuitry and how to write software.It also presents method of system’s debugging as well as the question which the design process needs to pay attention.The intelligence controller integrates prevention of burglary,fireproof and household electrical appliances as a whole.When something happened,the system can send text messages to host through GSM network.It also could upload the data and information to area controller by information of RS485.It is suitable for use in subdistrict which the function of RS485that is simply hardware,communication stability and transmission distance.Use of GSM network SMS platform is even more obvious advantages, there is no distance limit line, basically two-way communication anytime, anywhere.Exception the system can also record unusual historical data,that power-downs is not lost.Which could provide the primitive date for analysis police and fire alarm.When the master need to control the electrical appliances at home,who can momentarily carry on the wireless remote controller,which the wireless remote controller could not be influence in certain range of obstacles,the use is very convenient.If the master goes out,he also can use cell phone text messages to check the devices on the home and switch the remote control.This article designs the smart home controller that the structure is relatively simple,low cost,high reliability,and strong anti-interference,which has a practical effect.Our life quality conld be improved in a some extent.
