Research On Intelligent Home Control System Based On Internet Of Things

In recent years,with the rapid development of science and technology and the continuous improvement of the living standards,people's demands for the quality of life are also increasing.They begin to pursue a more comfortable and convenient way of life.Smart home can provide great convenience for people's life.Although smart home has been developing for more than ten years in China,it has not really entered the life of the general public.The application of smart home mainly appears in some high-end markets.The main reason is that the price is very high,and it can not really meet the actual needs of the ordinary people.In our daily life,Monitoring cameras are everywhere.A lot of video data are generated every day,left too much redundant data in storage space.If all these data are saved,it will be a waste of resource.To solve the above problem,a set of smart home solution based on the internet of things has been proposed.A smart home system has been designed by using the technology of internet of things,wireless sensor network technology and embedded control system.On the hardware side,the S3C2440 from Samsung is selected as the main chip of the system to set up the home gateway.CC2530 from TI is select as Zig Bee RF chip to organize wireless sensor network.Zig Bee wireless sensor network is connected to gateway by serial port.And gateway is connected to internet by ethernet.In terms of software,embedded technology is used to build gateway platform based on ARM,and Web technology is used to design user-interface.Users can remotely detect and control home appliances by mobile phones and other intelligent terminalsat at any time and anywhere.At the same time,I study the intelligent storage of surveillance video in home security system in detail.It is proposed that adding computing power in surveillance camera.When detecting moving objects in the video screen,the monitoring information will be stored,and when there is no moving object,it will not be stored.On the one hand,it can save a lot of storage space,on the other hand,reduce the pressure of data transmission to network bandwidth.According to the test,the system can realize the overall control and the remote access.Moreover,the man-machine interface is easy to operate.The cost of the system is relatively low,and it can meet the basic needs of the general public.Which will have an impact on the development of smart home market.The experimental results of intelligent storage show that the algorithm can detect the complete moving target and achieve selective storage of video,which can save a lot of storage space and save mach time in locating abnormal behavior.
